INTRODUCTION

Tamarinds belong to the family of leguminous plants called Fabaceae, which means

that they comprise of fruits with seeds enclosed within an encapsulated pod. Tamarind is one

of the most common and important trees of India, where it is widely used in cooking. India is

the leading producer, exporting several thousands of seed, seed power and fruit pulp every

year.

Tamarinds are tropical or semi-tropical evergreen trees that can reach a maximum

height of 80 feet, however most of the tamarind that grows in tropical regions usually reaches

a maximum height of 20 feet. The tamarind grows very slowly and withstand drought for

extensive period of time. The bark is thick and is usually brown in colour with dense foliage

that can often extend for a length of 20 to 30 feet.

The tamarind pulp separator machine works on intending to ease the traditional

method and saves both time and labour. The food industry is growing because of demand

both in the country and abroad. However the food processing industry needs tamarind juice

as an important ingredient. The Thailand Institute of Scientific and Technological Research

(TISTR) with support from the German Technical cooperation (GTZ) worked on the project

to develop the process for the food industry in Thailand, to enable the industry to compete

abroad. J M Industry Co. Ltd., a major food producer exporting to Europe, United States and

the Middle East, has also joined in that project.

OBJECTIVES

The traditional method of preparation of this pulp is a hand process that becomes

tedious and lengthy task to separate the pulp and seed from tamarind. Preparation of tamarind

pulp is one of the joint house hold work in most of the villages. The traditional method

consumes lot of time and man force. So our project “design and fabrication of tamarind pulp

separator machine” will help the farmers to separate the seeds and pulp efficiently in less

time. Since the machine will be economical and efficient in separating tamarind pulp and

seeds so most of the farmers can afford it. The machine will also reduce human labour, labour

cost, and time keeping the quality of the pulp more or less unchanged.

METHODOLOGY

Working principle

Presently, tamarind pulp and seeds are being separated by manual method that is hand

process, in which a mallet is used to apply impact load on tamarind. This involves heavy

manual work, requires more time and is tedious task to separate out pulp and seed. The

important feature of this machine is to reduce extra manual work as well as time

consumption.

In this machine, 1 HP motor of 1440 rpm with intermediate pulleys of suitable

diameter, which reduces the speed and substantially increases the torque output, are used.

Initially the dry tamarind without cover is put into the feed hopper. Then the feed

rollers guide the dry tamarind to the rim arrangement and also avoid jamming of tamarinds

in the rim arrangement. The feed roller is connected by pulley arrangement which rotates

the rollers in opposite direction so as to guide tamarind in downward direction in constant

flow. The rim arrangement of the mechanism which is driven by the motor takes the coming

tamarind from feed hopper and shears the tamarind pulp neatly over the blades arranged

opposite of the rim. Due to centrifugal force the tamarind is moved along the length of

blades. After shearing, the tamarind is passed through two rollers which are just arranged

below the rim arrangement. Here the seeds are removed from the pulp due the compression

action between the two rollers. After passing through these rollers the tamarind pulp and

seeds fall into a thin plate. The same motor is used to drive rim arrangement, feed rollers,

compression rollers and cam arrangement through belt drives.

Material used

Mild steel

Mild steel is used to make the supporting base and casing. The base and casing should be

made up of hard material. In metallurgy. Mild steel is defined as steel alloy with

approximately 0.05% to 0.25% carbon content with up to% mangnese content. Mild steel also

knows as plane carbon steel, is the most common form of steel because its price is relatively

low while it provides material properties that are acceptable for many application, more so

than iron. Mild steel contents approximately 0.05 to 0.25% carbon making it malleable and

ductile. Mild steel has irrelatively low tensile strength, but it is cheap and malleable surface

hardness can be increased through carburising. The density of mild steel is approximately

7850 kg/m3 and Young’s Modulus is 210GPA.

EN8 Steel

EN8 also known as 080M40. It is an unalloyed medium carbon steel. EN8 is a medium strength steel, good tensile strength. It is suitable for shafts, stressed pins, studs, keys etc. it is also available as normalised or rolled. EN8 is supplied as round drawn/turned, round hot rolled, hexagon, square, flats and plate

Raw materials:

A raw material is the basic material used in the productions of the goods, finished

products. The term “raw material” is used to denote material which is unprocessed.

Raw material

Marking:

Marking is the process of making visible impressions on the metal surface so that

required operations can be carried out as per the dimensions

Marking

Cutting:

The raw material cut into the required dimensions using a grinding wheel cutter.

Metal cutting is done by a relative motion between the work and piece and the hard edge

cutting tool, which is multi point cutting tool.

Cutting

Welding:

The assembly of base table are done by the process of welding. In this case the

process is done by “Arc Welding”. Arc welding is type of welding that uses a welding power

supply to create an electric arc between an electrode and the base material to melt the metal at

the welding point. They can use either direct or alternating current, and consumable or non

consumable electrode.

Welding

Drilling:

Drilling

Drilling is easily the most common machining process. Drilling involves the creation

of holes that are right circular cylinders. This is accomplished most typically by using the

twist drill. The chips must exit through the flutes to the outside of the tool. The cutting front

is embedded within the work piece, making cooling difficult. The cutting area can be flooded,

coolant spray mist can be applied, or coolant can be delivered through the drill bit shaft.

Hand Grinding:

Hand Grinding is the finishing process used to improve surface finish, abrade hard

materials, and tighten the tolerance on the flat and cylindrical surface by removing the small

amount of material..

Grinding

In grinding the abrasive material rubs against the metal part and removes the tiny

pieces of material. The abrasive material is typically on the surface of the wheel or belt and

abrades in a way similar to sanding. On a microscopic scale, the chip formation in grinding is

same as that found in other machining processes.

Testing Testing is an important phase of the project. It tells us whether the project is working to meet

the objectives or not. RESULT AND CONCLUSION

CONCLUSION

After the completion of the project work we tried it in our college machine shop and

we were pleased to note that it does meet the requirement for what it is meant.

We conclude that the mechanism adopted in the Design and Fabrication of tamarind

pulp separator machine is successful, because depending upon the climatic condition the

performance can be improved. This machine reduces human effort as well as time involved in

the manual operation of people so that improving their working method.

FUTURE SCOPE OF THE PROJECT

We feel the project that we have done has a good future scope in AGRICULTURAL

SECTORS. The main constraint of this device is the high initial cost but has low operating

costs.

The device affords plenty of scope for modifications, further improvements &

operational efficiency, which should make it commercially available.

Some heating arrangement can be integrated in the machine so that wet tamarinds can

also be separated in the machine, the weight of the machine can be reduced so as tho make it

portable.

Some mechanism can be adopted for removing the cover of tamarind pod initially in

the machine itself so that there is further reduction of labour and time required for separating

the tamarind pulp and seeds, thus increasing the output of the machine by some extent.
