Soft ice cream machine, also known as batch freezer, is an automatic equipment specially designed to produce frozen dessert-ice cream. According to the purpose, ice cream machines can be divided into large-scale freezing machines used in factory assembly lines and commercial ice cream machines used in catering industry.
There is also a domestic ice cream machine for family use, which does not contain any electromechanical parts, so it is no longer discussed here. Only the commercial ice cream machines used in restaurants are discussed here.
Some ice cream machines have a pre-cooling function, which is used to keep the temperature in the storage tank at about 5- 10 degrees, thus playing a fresh-keeping role. In actual use, some merchants will claim that their ice cream machines don't need cleaning, which is actually misleading.
We know that the ingredients of ice cream are mainly dairy products, and dairy products are very vulnerable to the destruction of bacteria and quickly corrupt, especially in hot summer. If the machine is not cleaned at night, the bacteria of ice cream will definitely exceed the standard the next day. Once the problem is given to consumers, it is not worth the loss.
Again, we remind the merchants to pay attention to the hygiene problems in the daily operation, and we must ensure hygiene and safety. Another problem of not cleaning the ice cream machine at night is to go back to the liquid slurry for stratification, and the ice cream made in the production the next day has a very bad taste. Because of the natural precipitation of water in the ice cream, some components in some raw materials will react with metal ions, resulting in the blackening of the feed liquid.
