A Quick Guide To Ice Cream Machines |
Posted: April 16, 2018 |
The affair of humans with ice cream is centuries old. Though the invention of this sweet dessert is uncertain, perhaps the practice of fruit ices, chill wines and juices gave rise to frozen milk and cream mixtures. This frozen dessert was expensive until the invention of refrigeration. However, with advancement in refrigeration and ice cream machines in UK, ice cream soon became a popular demand. Let us have a look how this sweet, frozen, delicious dessert is made. Materials requiredAt present, ice cream is prepared from a blend of different types of dairy products, like milk, condensed milk, cream, and butterfat. Sugar, flavorings, and additives are added to enhance the taste and property of ice cream. In some flavorings, eggs are also added. Additives act as stabilizers and prevent heat shock and formation of ice crystals during processing. The most common additives used for the preparation of the ice cream is guar gum. If we talk about ice cream flavors, they have come a long way after standard vanilla. Now there are countless flavors of ice cream available. Manufacturing processMixture Milk is refrigerated in large tanker trucks. It is pumped into storage silos with controlled temperature which is further shifted to stainless steel blenders. A pre-measured quantity of eggs, sugar, and additives are blended with the mild for a few minutes. Pasteurization The blended mixture is shifted to pasteurization machine to effectively kill and bacteria. Texture With the application of powerful air pressure, the hot mixture is forced out through a small opening into the homogenizer. This step is done to break down fat particles so that it doesn’t get separated from the rest of the mixture. A homogenizer is essentially a high-pressure piston pump. This recipe is blended for some extra time and is drawn into the pump cylinder. Cooling This blending is piped back to the pasteurizer where it is cooled. Then it is again pumped to tanks where it is allowed to settle for four to eight hours. This stem makes ingredients to blend. Flavoring Ice cream mixture is then shifted to stainless steel vats where flavorings are piped and allowed to blend thoroughly. Freezing This combination is then pumped to freezers where liquid ammonia is used as a freezing agent. To bring the consistency of soft serve ice cream, air is injected into this mixture. The last step in the making of ice cream involves adding sweetened chunks, packaging and bundling of the product.
