1. Sterilization.
After we have stirred all the ingredients evenly, we need to use a steam generator to sterilize the ingredients. Of course, we need to control the temperature of the steam generator during the sterilization process. If the temperature is too high, it will affect the quality of the ice cream. Taste, if the temperature is too low, the sterilization will not be complete, so how to effectively kill bacteria without affecting the taste of ice cream?
In fact, the ice cream factory uses a steam generator to sterilize, which is mainly pasteurized. The ice cream factory will use a steam generator to sterilize at a constant temperature. It lasts for about half an hour to completely kill bacteria and germs. , mold, etc. are all killed, which can also fully ensure that the hygiene and cleanliness of the ice cream reaches the standard.
Why use a steam generator for sterilization? What are the benefits? In fact, the ice cream factory can greatly reduce the nutritional loss of the ice cream while using a steam generator for pasteurization, thus ensuring the original taste of the ice cream. And the steam produced by the steam generator is very clean, green and pollution-free, and will not produce any residues during the production process, which is particularly environmentally friendly and healthy.
2. Homogenization treatment.
The pasteurization method also needs to homogenize the raw materials, and the temperature needs to be controlled during homogenization. If the temperature is too low, the viscosity of the mucus will increase, resulting in problems with the homogenization effect. If the temperature is too high, fat accumulation will occur, and the fat rate will also be reduced.
The steam generator is used in the ice cream homogenization process, mainly because the steam generator can accurately control the temperature within the relevant range, and can continuously produce constant temperature steam, and the steam homogeneous ice cream product has a fine texture , Lubrication, stable and long-lasting shape, can improve the expansion rate, reduce ice crystallization, etc., and when the ice cream mixture is mixed, it can be better homogenized with a steam generator.
Of course, temperature is very important in the homogenization process, and there is another point that is also very important, that is, pressure. During the homogenization process, it is necessary to control the pressure vapor pressure within a certain range, and the pressure should not be too low or too high. The steam generator is also a pressure vessel device, and it will generate a certain pressure while heating up, so when using the steam generator to raise the temperature, it is necessary to adjust the pressure to the pressure required for homogeneity, and increase the temperature and pressurize, so that The homogenization effect will be better.
