As shown in the table above we want to set up a program which will achieve maintaining of high pasteurization ice-cream mass at 4°C. Program zajema 5 aktivnih korakov (step). The machine starts with slow mixing and heating the mixture of ice cream. When the mixture reaches 55°C fast mixing starts (untill high pasterization – 90°C). With this we will achive a well mixed - conected mass. Rapid mixing is used also in cooling phase untill temperarture of 55°C is reached. In the temperature range (55°C ~ 4°C) we want to have slow mixing and slow cooling of ice-cream mass. With this we prevent the formation of ice on the wals of the basin. When the mass reaches the maintenance temperature (4°C) we want, that the appliance warn us in three periods. For maturation – Maintenance of the mass at 4°C we use slow cooling with slow impulse mixing.

Just a cleaned and desinfected appliance can be used for mass preparation. To get optimal results it is needed to have proper quantity and proper quality of the mixture. The amount of the mixture shall conform to the technical characteristics of the machine. During preparation and loading it is needed to comply with the minimum and maximum mixture ammounts in the basin. They are reported in below table: All performance data is based on standard ice cream mixture production. When producing mixtures, which include ingredients or additives that increase in volume during heating and/or cooking, the maximum mixture quantity must be reduced in accordance with the recipe.

10.7 SMALL AMMOUNTS OF ICE-CREAM MIXTURE

To prepare small amounts of ice mass it is necessary to install a flue damper on the agitator. Mixing smaller quantities without flue dampers cause air suction in the mix. When the mass occupies more than half of the vqasque volume, the flue damper is not needed. For small ammounts of ice-cream mixtures it used reduced heating and cooling. When entering the stage of preparation or refrigeration, the reduction is always off. If the key of curently selected mode is pressed once again for more than 3 seconds the reduction is swithched on or off. If the reduction is activated the led of the active key is blinking.
