A Taylor 104 Batch Ice Cream Freezer 3 L is a type of refrigeration appliance used in commercial kitchens and food processing industries to rapidly cool or freeze food products. The process involves lowering the temperature of food from a hot or warm state to a safe storage temperature in a short period of time. Blast chillers are typically used to cool cooked food products, such as soups, stews, and sauces, to prevent the growth of bacteria and prolong the shelf life of the food. Shock freezers, on the other hand, are used to freeze food products, such as meats, fish, and vegetables, to preserve their freshness and quality. Both blast chillers and shock freezers work by blowing cold air over the food product, which quickly lowers the temperature of the food. This process is much faster than traditional cooling or freezing methods, which can take hours to bring food products to a safe temperature. The use of blast chillers and shock freezers is particularly important in the food industry, where food safety regulations require that food products be cooled or frozen to safe temperatures as quickly as possible. These appliances also help to maintain the quality and taste of the food, as they prevent the formation of ice crystals and other unwanted textures that can occur with slower cooling or freezing methods.
