Enzymes

Enzymes are some of the most important and complex proteins found in nature and are vital to all biological systems. Brewing could not exist without the enzymatic actions activated from grains during the malting process. Understanding these natural enzymatic systems allows brewers to apply them to the betterment of the art of brewing.

Novozymes, the world’s largest manufacturer of enzymes to the food industry, developed the fi rst commercial enzyme for beverage processing over 35 years ago. Together, Novozymes and Gusmer have since dedicated many years of research and application development to the continued advancement of enzyme preparations for use in brewing. Today, enzymes are used by commercial brewers to increase extract and attenuation, control diacetyl, improve fi ltration, and more. They are a fundamental tool for consistent production of high quality beer.

Novozymes produces brewing enzymes through natural fermentation processes, which are purifi ed and standardized on these key activities. These enzymes can be applied throughout the brewing process to increase process effi ciencies, brew to brew consistency, and overall quality. They can also allow for the creation of unique and alternative-style beers.

Enzymes in brewing:Enzymes are a protein molecule with a characteristic sequence of amino acids that folds into itself to produce a distinct 3-D structure. The complexity of the structure creates very specific activities for each enzyme. Brewer’s grain contains inactive enzymes that through the malting process become active and available to react with specific substrates in the grain. Some of the critical enzymatic activities developed during malting that are essential for brewing are amylases, proteases, lipases, and cellulases.

Cask Ale

Cask Ale Preparation Preparing beer for cask packaging is a key part of the overall process for producing quality and consistent beer that will always delight your customers.

After fermentation is complete and the temperature reduced to between 6°C and 8°C (43°F - 46°F), and brink yeast has been recovered, the residual ale yeast will naturally flocculate within the fermenter and can be drawn off, or else a portion of beer can be run through a centrifuge and a residual yeast count of around 1x106 cells obtained by bypassing some of the flow.

The green beer is then moved to racking tanks and is stored at this stage for typically no more than 24 hours. As the green beer is transferred, auxiliary finings are added. These are typically silicates or alginates and these bind and fine out residual protein from the beer and protect the beer from producing a haze. The fermentable residue can also be controlled by the addition of priming sugar, usually sucrose.

Beer is then run to the packaging line where each cask has a small quantity of isinglass finings added.

Upon delivery to the retail outlet the casks are stillaged on their bellies, the keystone tapped and a soft spile is inserted in the hole in the bung. Secondary fermentation takes place in the cask producing natural carbonation of the beer and the degree of fermentation can be judged by the level of gas escape through the soft spile.

Once the level of carbon dioxide production slows then the soft spile is replaced with a hard one which ensures that the entrained carbonation in the beer remains in solution and provides a perfectly conditioned beer.

Once the beer has stopped ‘working’, the isinglass plays its part in the process. This removes the residual yeast as isinglass has a net positive electrostatic charge while the yeast is predominantly negative and this facilitates the rapid and complete settling of the yeast into the belly of the cask.

The keystone lies just above the cask belly, and as beautifully conditioned and sparkling clear beer is drawn off, the sediment remains undisturbed in the cask. Once the cask is below half full, it is gently stooped forward so that all but the last few pints can be dispensed. It is important to replace the hard peg between sessions to maintain condition.

Finings

AB Vickers Finingsand Antifoam AB Vickers is the premier name in antifoam, and both kettle and cellar finings. Their roots are in the United Kingdom where the importance of finings both in the brewhouse and cask are well understood. Gusmer Enterprises is proud to offer these finings in North America.

Cryofine (CRY 151) Cryofine is purified isinglass in a convenient powder form. It is added to beer at the end of fermentation to speed maturation and improve filtration by removing yeasts and protein particles. For the purposes of rapid dissolving, enhanced performance, and long shelf life, the isinglass in Cryofine has been pre-hydrolyzed and freeze-dried. Cryofine also contributes to the actions of both silica gels and PVPP.

pack size: 1 lb dose rate: 1 - 5 g/hl; 0.05 - 0.2 oz/10 bbls

Breakbright Super Tablets (BST 311) Breakbright Super Tablets are an extremely convenient way to promote a bright and flocculent kettle break. Breakbright Super Tablets consist of kappa carrageenan derived from the red seaweed Eucheuma cottonnii. Simply drop these tablets into the kettle 10 minutes before the end of boil and experience brilliantly clear wort at knockout. Beer will benefit from this product from wort cooling through filtration.

pack size: 25 kg dose rate: 3 - 5 g/hl; 0.1 - 0.2 oz/10 bbls

Foamsol S (FCS 130) Foamsol S silicone antifoam is an inert polymer which is highly effective in foam suppression in both the kettle and fermenter. Foamsol S preserves foam positive proteins which contribute to the head retention quality of beer. One of the most important benefits of Foamsol S is the increased iso-α-acid utilization from hops. The effect of controlling foam in the fermenter will retain iso-α-acid and allow a reduction of up to 15% of the kettle hops. Other benefits include increased kettle and fermenter utilization, as well as eliminating the loss of product from foam during fermentation.

pack size: 25 kg dose rate: 1 - 8 ml/hl; .03 - 0.3 oz/10 bbls


Chill Proofing

PQ Silica GelsCustomers will judge your beer on a number of different parameters: aroma, flavor, head retention, and clarity. These last two are not mutually exclusive. You can have one and not the other. Chill haze is caused by the com-plexing of proteins and polyphenols which are insoluble at cold serving and storage temperatures. PQ’s BRITESORB Silica Gels remove only the proteins that cause haze. These highly selective adsorbents leave the larger proteins that contribute to the brilliant, long lasting foamy head that you have worked so hard to achieve.

BRITESORB A100 For chillproofing lighter style beers, BRITESORB A100 is the most effective choice you can make. The surface of BRITESORB A100 is engineered with moderately sized pore openings that block the entry of larger foam-enhancing proteins. At the same time, the large surface area inside the pores ensures the adsorption of virtually all proteins that cause chill haze. Because BRITESORB A100 is a hydrogel, it is non-dusting and has a minimal content of fine particles. As a result, you should expect higher filtration rates and longer filter runs. Available in 50 lb bags.

dose rate: beers up to 65% malt ratio: 40-50 g/hl; 1.4 - 1.8 oz/10 bbls beers greater than 65% malt ratio: up to 80 g/hl; 2.8 oz/10 bbls

BRITESORB D300 For chillproofing a wide range of higher malt ratio beers, BRITESORB D300 can’t be equaled. This silica xerogel uses the same adsorption principles as BRITESORB A100. In addition, the surface structure is activated by a pat-ented process that increases chillproofing effectiveness. Filtration is also improved because, unlike other xerogels, BRITESORB D300 is manufactured to a larger particle size that won’t slow flow rates. Available in 40 lb bags.

dose rate: beers up to 70% malt ratio: 25-40 g/hl; 0.9 - 1.4 oz/10 bbls beers greater than 70% malt ratio: up to 60 g/hl; 2.1 oz/10 bbls

Preparation of BRITESORB BRITESORB should be slurried with deaerated water at 10 percent of total slurry weight (100 grams per liter). The slurry should be continuously agitated during mixing and dosing to keep it in suspension. Carbon dioxide should be bubbled through the slurry to minimize oxygen pick-up.

Dosing Continuous In-line Method The BRITESORB slurry is proportioned into the beer on its way to final filtration. In order to provide a minimum contact of 10 minutes, a buffer tank is recommended. The BRITESORB manufacturing process optimizes particle size for compatibility with your current filter aid usage.

batch Method Add BRITESORB slurry to beer while filling the finishing tank. Slurry should be proportioned into the beer through-out the entire filling operation. Once the adsorption process is complete, particles settle and are easily removed dur-ing tank cleaning. Inadvertent over-dosing or contact time of several days causes no negative effects in the beer.

• Reduces haze-causing polyphenols • Extends shelf life • Easy to use Even after filtration, beer, no matter how clear, contains dissolved phenolic compounds and proteins derived from the raw materials. After a relatively short time, these compounds form complexes which later cause turbidity.

Haze in beer is caused mainly by polyphenol-protein complexes. Divergan F PVPP (polyvinylpolypyrrolidone) selectively adsorbs the polyphenols that cause turbidity. Removing the excess polyphenols responsible for this problem considerably improves the colloidal stability of beer. There is evidence that this also improves the stability of the taste, as the flavonoid polyphenols, in particular, are prone to polymerize to products of higher molecular weight that have a bitter flavor.

UsageThe preferred method of introducing Divergan F is to meter it continuously into the beer stream with a metering pump. Divergan F can also be added together with the filtration agent. Provision must be made for a contact time of at least 3 minutes. In calculating the contact time, the sludge capacity of the filter must also be taken into account.

For breweries without continuous metering capabilities beer can be treated in the tank in a batch method. This is best done the day prior to filtration. Mix enough Divergan F with deaerated water to treat the amount of beer in the tank. Depressurize the tank and introduce

the Divergan F to the beer through the spray ball. Flush the spray ball line with a small amount of deaerated water to make sure all of the slurry is added and so not to clog the line. Repressurize and bung the tank. Allow the Divergan F to sediment out to the bottom. Filter beer as you would normally.

In some breweries, silica gel is added together with the PVPP to the same supply tank. This gives a highly efficient combination of filtration and stabilization effects that also saves on capital investment, as no further equipment is required.

DosageThe optimum rate depends on many factors; contact your Gusmer Representative for a recommendation. Stability, raw materials, cellar equipment, degree of clarification prior to filtration, and the type and quantity of other stabilizing auxiliaries used are all considered when determining dosage. General recommendations are found in the table below.

PackagingDivergan F is available in 1 kg or 5 kg packs, as well as 20 kg drums.

A Reusable Form of Divergan PVPPDivergan RS is intended for reuse and is a highly economical option due to recycling of the PVPP. The recycling process does require special filtration and regeneration equipment. Consult your Gusmer Representative for further regeneration options.


D.D. Williamson Caramel for Brewing

Caramel in the Brewing Process A valuable brewing ingredient for more than a century, caramel contributes to the character of beer on every continent. Caramel provides color, flavor, and consistency in beer. It also has applications in a variety of related products, including cider and non-alcoholic malted beverages.

What is Caramel? Caramel results from the controlled heat treatment of carbohydrates, typically glucose syrup. The glucose and food-grade catalysts are used to facilitate the browning process and provide stability. The finished beer caramel, a long polymer chain, is a positively-charged colloidal solution and thus stable in beer, which is also positively charged (because of proteins). Caramel is inert, physically stable when stored properly, and bacteriastatic if not totally sterile.

Why Use Caramel? Caramel is a great way to adjust beer color throughout any part of the brewing process. Caramel allows you to adjust color in the kettle and as late as final filtration or serving tank. With caramel you can darken your beer without adding the astringent flavors associated with dark malt.

Dosage Dosage will vary by style. Traditional ales contain 0.02% or more of caramel coloring to add color and some flavor character. Certain dark beers, including some Stouts and Bocks, might require higher caramel dosage. Lagers require more minimal caramel amounts for color consistency (typically 0.01%) than other types. Adjusting a lager type beer to a Bock beer color would require an addition of 0.05-0.075%.

Color with Confidence – every day more than 1.5 billion servings of food and beverages containing D.D. Williamson colorants are consumed around the globe. With seven caramel manufacturing sites on five continents, D.D. Williamson is the world leader in caramel color.

Oak

Gusmer’s Oak adjuncts offer the ability to add or supplement oak character, from a wide selection of oak varieties and toast levels, without investing or maintaining any actual wood cooperage. Our American oak lends itself perfectly to Barley Wines, Imperial Stouts or an authentic IPA. Use our French oak products to provide the oak character associated with Lambics, while still keeping any wild yeast or bacteria safely enclosed in a stainless steel vessel.

As producers of granular oak and oak chips for the beverage industries for over 30 years, our commitment to quality and consistency is uncompromising. Only the highest quality American and French oak from premium heartwood qualifi es for our programs. Or proprietary toasting processes brings out very distinct oak attributes, such as vanilla, butterscotch, clove, smoke, and others. Consistent, predictable results are the hallmark of Gusmer’s oak program. Our adjuncts allow brewers more options to compliment fl avors and aromas, tactile characteristics, and color stabilization.

We offer both granular oak and oak chips, in a range of sizes and toast levels, and full product support to assure the proper application in your brews. See page 14 for the complete selection.

Finishing - brite beer Tank: Adjust beer fl avor and aroma during storage in the brite beer tank.

aging / barrel supplementation: Renew oak fl avors and aromas in neutral barrels.

Dose Rate: 70-250 g/bbl (for oak fl avors and aromas thatrange from subtle background notes to bold oak character)

blending beer: Dose at a high rate directly into a smaller volume of beer to make a concentrated blending beer for precise blending back into larger fi nished brews at the brite beer tank.

dose rate: 1,000-2,500 g/bbl

The full fl avor and aroma will be extracted from the oak in 3-5 days. The oak can be easily removed by decanting or fi ltering the beer after extraction. Gusmer also offers oak adjuncts in infusion bags for use in a fi nishing or brite beer tanks. The infusion bags allow for full extraction of the oak, while keeping the oak fully contained for convenient removal.

Filtration

Whether it’s pressure leaf fi lters or candle fi lters, the basis for all good fi lter cakes is a sound pre-coat, and Gusmer has been manufacturing the fi lter pre-coat materials that are used in beer fi ltration for decades. Gusmer’s Cellu-Flo fi lter aids are widely used throughout the industry as a pre-coat material, because of their ability to form a fi brous matrix on the fi lter screens that provides a proper site for fi lter cake formation. This fi brous matrix also serves to protect the fi lter screens, virtually eliminates bleed through, adds cake stability, and allows for a quick and clean cake release at the end of the fi lter cycle.

Cellu-Flo fi lter aids are available in many different fi ber length distributions and formulations, including both cotton and wood pulp formulations, uncharged and charge modifi ed formulations, and fi ber blended products.

Recently introduced is the Cellu-Flo FB series, which is a fi ber/perlite blended pre-coat and bodyfeed material especially designed for quick pre-coat cycles on rotary vacuum fi lters, plate fi lters, pressure leaf fi lters, and candle fi lters. Cellu-Flo FB is available in three different formulations for coarse and polish fi ltrations.

Filter Sheets Filter Sheets

Operation

Typically, a filter press consists of a series of plates equipped with inlet and outlet ports. Depending on the type of press, the ports may be internally or externally ported. When the press is closed and tightened through manual or hydraulic means, the plates, gasketed ports, and sheets are closed to form a tight seal for feed and filtrate passage. The unfiltered product passes through the inlet ports of the plate to the depth filter sheet. The depth filter sheet separates the undesired contaminant and allows the cleaned product to flow to the outlet plate. The outlet plate distributes the cleaned product to the discharge or outlet port.

Advantages of Filter Presses

• Very versatile—full range of beer filtration applications

• Large filter area with additional surface area available with more plates

• Flexible, modular design with ability to conduct two stage filtrations

• Good process scalability from bench to production scale

• Consistent and reliable filtration results

• Low maintenance costs

The versatile sanitary housing line accommodates either 12” or 16” diameter Cellu-Stack fi lter modules with the effective fi ltration surface area ranging from 17.7 ft2 - 160.0 ft2. All housings are available in 1, 2, 3, or 4 stack versions which can be modifi ed with the use of Cellu-Stack take-up adapters to accept fewer stacks for partial batch runs or other applications requiring fewer stacks. ASME code housings are also available if required.

Cellu-Stack Application Notes: • Place a quick acting check valve at the housing outlet to avoid integrity

breaches that can be caused by backpressure

• Double check that all gaskets are in place and in good condition to ensure optimal sealing

• If fi lter life is not fully exhausted by a single fi ltration, DO NOT remove used fi lters from the housing for storage between uses. Instead, used fi lters can be stored IN the housing by following these steps:

• Shut Down: After completion of the fi ltration cycle, sanitize the fi lters with the same method used to prepare the fi lters (ex: steam or hot water fl ush)

• Storage: Drain the housing, apply 2 psi gas pressure (ex: CO2, nitrogen) while the housing is still warm (to avoid a vacuum upon cooling) & close all ports

• Restart: When restarting for another fi ltration cycle, repeat the sanitization procedure just as you would for normal fi lter preparation

Filtration

Installation: • Assure that the housing, pressure gauges, valves,

gaskets, and o-rings are in good working order (housing o-rings should be replaced on a regular basis).

• Carefully remove the cartridge from the packaging material and inspect. Use caution when opening the filter bag – scissors are recommended. Each filter cartridge is stamped with the grade and comes with a quality certificate in the box. Verify that the correct filter is being installed for the intended application.

• Wet the o-rings with water and install into the housing, being careful not to roll the o-rings upon installation.

• Run ambient temperature water* through cartridges under a little back pressure to fully wet out the filter.

Sterilization & Cleaning: • The prefilters and sterile filters should not be sterilized

in-line with the bottling equipment. Bypass the filter housings and sterilize separately. EMD Millipore recommends the use of hot water* (180°F) for 30 minutes for sterilization of filters and filter housings (time period starts when the housing outlet comes to temperature). Once the proper temperature is reached, take care to use only a low hot water flow and low differential pressure, such that it maintains the housing temperature.

• Each hot water cycle should always be preceded and followed by an ambient water* rinse cycle.

• If hot water is not available, the filters are compatible with a wide range of sanitation chemicals. Please consult your Gusmer representative for specific information.

• Ensure that filter housings remain fully vented during cleaning and sterilization.

• Filters can be flushed with warm water* in a forward direction after use to remove any soluble residue on the media. The flow rate should be roughly equal to that of the process flow during operation.

• Some filters can be back flushed. Please consult your Gusmer representative for specific information.

• Avoid pressure shocks and water hammer – especially during cleaning/sanitation with hot fluids.

Operation: • Differential pressure (inlet minus outlet P) should be

monitored regularly. Differential pressure increases as the filters plug, eventually leading to a loss of flow through the filter. Differential pressure increases exponentially. It may take many weeks to reach 80% plugged, but only a few hours for the final plugging to occur.

• A common practice is to terminate the filtration and clean or change the cartridge(s) when the differential pressure reaches 30 psi.

• Operate the process at the lowest, consistent flow rate to have a positive effect on filter performance. A higher face velocity leads to faster plugging.

• Avoid pressure shocks and water hammer on the line.

* Use filtered, softened water for wetting, cleaning, and sterilization to avoid fouling the cartridges.

Application Notes forEMD Millipore Filters


Integrity Testing: • Integrity testing is only conducted on final membrane

cartridges and is conducted per the recommended specifications of the manufacturer for the specific membrane used. Integrity testing is conducted after the sanitation cycle, both prior to and after the bottling run. There are a few different methods for integrity testing, of which the bubble point and pressure hold methods are the most common. The bubble point method is recommended for housings with three or less cartridges and the pressure hold method is recommended for housings with greater than three cartridges. Please consult your Gusmer representative for detailed information on integrity testing methods and specifications.

• Every EMD Millipore sterile membrane filter cartridge is 100% integrity tested by EMD Millipore prior to packaging. Damage caused to cartridges by shipping, installation, process improprieties, or housing and valve issues are usually manifested as a gross integrity test failure.

Cartridge Storage: • Intermediate storage (overnight or over a weekend)

can be done in the filter housing. Flush the filters with warm water, sterilize the housing, and pressurize with 5 psi of nitrogen. The nitrogen keeps the housing under a positive pressure.

• Long term storage is best done outside of the filter housings. Four inch PVC piping capped at both ends is frequently used to store the individual cartridges in a solution of 350 ppm sulfur dioxide that has been adjusted to a pH of 3.5 with citric acid. This solution

should be tested every month and replaced as necessary. Remove o-rings from the cartridges prior to storage in the sulfur dioxide solution and store the o-rings in a clean and dry place (sulfur dioxide solution will make the o-rings swell).

• Reinstall the o-rings, rinse, sterilize, and integrity test stored cartridges prior to resuming bottling filtration.

Total Cost of Filtration: • An efficient brewery must operate on a Total Cost of

Filtration basis. This method of operating recognizes that superior filter performance will yield better process economics over time.

• A Total Cost of Filtration approach also recognizes that factors influenced by filter performance are often more costly than the filters themselves. These factors include:

• Filter Cartridge Cost • Beer Lost or Damaged • Bottling Line Downtime and Labor • Cleaning and Sterilization Water and Chemicals • Quality Assurance Personnel and Materials • Product Holds • Product Spoilage and Recalls

• A high quality filter cartridge is key to maximizing total throughput and reducing the Total Cost of Filtration.

Measurement principle:

The beer sample (10 ml) is sucked into the measuring cells by means of a pump. Alcoholic content, extract, and density are measured by using thermal measuring effects. Derived constituents such as original wort, apparent extract, and osmotic pressure also will be determined.

Calibration:

The device may be calibrated by using a corresponding reference beer. You can store 18 different sets of calibration data (for example Pilsner, strong beer, non-alcoholic beer). You can also change from one product to another without having to undertake a new calibration. Reference beer calibrations can be conducted at our Analytical Laboratory in Napa, CA. See page 43 for information about Gusmer’s Brewing Analytical Services.

Interfaces:

Parallel interface / recording printer: The device has a parallel interface for connecting to a normal commercial printer. A recording printer is also included.

Illustrated Guide to Microbes and Sediments in Wine, Beer and Juice by Dr. Charles G. Edwards

At last, one of the most useful books for beer microbiology is now available…a “must-have” for microscopic examination and tentative identification of microorganisms and sediments in wines, beers, and juices!

Illustrated Guide to Microbes and Sediments in Wine, Beer and Juice is a microscope companion book that includes over 30 different species of yeast, bacteria, and mold commonly associated with beer, as well as frequently encountered sediments. This book is an extensive compilation of photographs and reference information printed on durable, spill-resistant paper and spiral bound so the pictures lie flat when in use with a microscope.

The microorganisms were obtained from culture collections located around the world. Each organism is featured in three photographs: (1) a typical colony grown on commercially available culture media; (2) a color stain; and (3) a phase contrast view of the microorganisms grown in wine, beer, or juice.

This volume includes translations of the following languages: English, French, German, Italian, Spanish, and Chinese. Therefore, it is an essential resource for brewers worldwide. It’s a comprehensive reference book that will quickly become a standard for any technical brewing library.

Brewery Hose

The inner lining of a food or beverage hose must also be resistant to conventional cleaning agents and disinfectants. Chemical resistance tables are a big help in this respect because they include basic cleaning agents like water, steam, and sodium hydroxide solutions, plus various chemical combination preparations, with information on the maximum duration of exposure, working temperature, and concentration.

Ruling out hygiene risks The inner lining should also be extruded instead of being made using the winding process. A wound liner could come apart at its winding seams after being subjected to mechanical pressure or excessive heat, and thus turn into an acute food safety weakness.

Clamp bands and tightening straps are a further hygiene risk. This is due to the fact that the hose nipple can become separated from the hose if the line becomes severely bent at the hose end, forming a so-called dead space in which the medium can collect. In turn, this results in dirt cavities, which may not be possible to adequately rinse and disinfect.

Clamp or segment fittings present a better alternative, for this reason they are used, above all, in the pharmaceutical and chemical industries. They are also available in certain nominal widths for the stainless steel types required in the food industry. Pressed fittings, however, are felt to provide a much higher level of hygiene. In the case of good fitting systems such as “Pagufix 3000”, the pressed sleeve is longer than the hose nipple. This prevents any dead space from forming should the hose be bent. Pressed and clamp fittings provide maximum reliability, moreover, because the hose/fitting connection is stronger than the

Cheap is not always good value for the money Although the durability of the hose material cannot be seen at first glance, as a rule it quickly becomes obvious when the hose is put into service that material which may have seemed to be expensive at the beginning turned out to be a better deal thanks to its service life, reliability, and safety. Therefore when selecting a hose and fitting system, one should take into account not only the purchase price but also the possible follow-up costs resulting from replacement and disposal of material that experiences premature fatigue, in accordance with the total cost of ownership process. And burst hoses can also result in unexpected costs due to production disruptions and even personal injuries.

Suitable for use in the beverage industry? Not all hoses are the same, and that holds true in particular for beverage hoses. Many of the types of rubber, fillers, plasticizers and other anti-aging agents offered on the market are unsuitable for use in the food and beverage industry. Some of them do not conform to the XXI recommendations of the German Federal Institute for Risk Assessment or the internationally recognized directives of the Food and Drug Administration (FDA), quality control reports or certificates of conformity issued by renowned institutes provide the necessary certainty that the hose line materials are indeed suitable for transporting alcoholic and non-alcoholic beverages. The inner lining of a food hose must be smooth, homogenous, and nonporous so that it does not transfer odor or taste to the food being processed.

Don’t cut corners in the wrong places Beverage hose lines take on a wide range of jobs in breweries and the beverage industry, and, in some cases, work under extremely tough conditions. But the importance of these hose lines as production equipment is frequently underestimated. Indeed, extreme care must be taken when choosing a hose to satisfy hygiene requirements and ensure operational reliability.

Reliable hygiene is of the utmost importance in the brewing and beverage industry. The hose material and fittings for beverage hoses must be selected carefully to ensure a high level of hygiene, a long period of service, and minimum need for repairs. The high-quality rubber compounds and pressure carrier materials used in high-grade hoses, such as “Blaudieck” beverage hoses or “Purple Snake”, payout in the end in terms of long, reliable service life. Precise extruding and product-specific braiding technologies and vulcanization processes likewise contribute to the high quality of the hoses.

High Quality Brewing Hose


Brewery Hose

bursting pressure of the hose. Thus, there is no risk of a hose rip-out; it also prevents a pressurized hose from fl ying loose and injuring people or damaging objects inthe area.

Prevention paysHose lines made of rubber and plastic- rubber composites are subject to natural aging. Mechanical and thermal infl uences can accelerate the aging process. Precautionary checks - either in-house, or, if possible, by a professional hose line assembler – can help detect and exclude possible risks early on.

Purple Snake was developed by brewing specialists, in conjunction with its German manufacturer. This hose offers unsurpassed quality in a brewery hose and has experience along with an incredible reputation in world famous breweries across the globe. Purple Snake offers incredible fl exibility in the coldest cellar, and this fl exibility is not provided at the expense of durability. The white inner lining of Purple Snake hose is impervious to brewery chemicals and will not contribute off fl avors or harbor microorganisms. Flexibility, pressure resistance, and long service life - even under extreme working conditions – are additional advantages. Purple Snake is an investment you will make in your brewery that will offer excellent returns for years to come. Gusmer also offers Blaudieck hoses as a high quality option at a lower price.

C = A + B = quantity of mix

c = property of mix

Example: If 85 bbls of water at 120° F are mixed with 55 bbls at 212º F, what is the temperature of the mix?

Let X = ºF of the mix; then

85 x 120 + 55 x 212 = 140 X, and

X =

Example: How many bbls of beer of 3.8% and 3.2% by weight of alcohol, respectively, must be blended in order to obtain 650 bbls of beer of 3.6% alcohol?

Let X = number of bbls of 3.8% beer. Then (650 – X) = number of bbls of 3.2% beer. Substituting in formula:

X x 3.8 + (650 - X) x 3.2 = 650 x 3.6

0.6X = 260

X = 433

Answer: Mix 433 bbls of 3.8% beer with 217 bbls of 3.2% beer.
