How to choose sterilization machine in food and beverage production?
Tube-type and plate-type complete sterilization systems are often used for continuous sterilization of fruit and vegetable puree, raw juice, concentrated juice, milk, juice drinks or similar products; The milk sterilizer is also an important part of the beer packaging production line. The main task of the sterilizer in the beer packaging production line is to kill the yeast and other miscellaneous bacteria remaining in the liquor, ensure the biological stability of the beer, and make it conducive to the long-term preservation of the beer.
working principle
First, the tubular heat exchanger will heat the material. When it is heated to 138~150 ℃, generally 100 ℃ is enough to kill ordinary bacteria and microorganisms, and then keep the material in this high temperature environment for 2~4 seconds to reach the commercial sterile level; Then it is filled in aseptic packaging container in aseptic environment. The sterilization process of the sterilizer is actually high temperature sterilization, which can completely kill the microorganisms and spores that can cause material corruption and deterioration, and the high temperature can greatly preserve the original flavor and nutrition of the food. The sterilizer can not only sterilize the product and its packaging, but also has certain preventive effect. This strict processing technology can effectively prevent the secondary pollution of the food and greatly extend the shelf life of the product. There is also a method of high intensity ultraviolet circulation sterilization, which uses high intensity ultraviolet for sterilization treatment. However, more enterprises generally use high-temperature sterilizers.
Product characteristics
The sterilizer is a machine specially used for sterilization of products and product packaging. There are many functions and types of sterilizers. In short, the characteristics of different sterilizers are not the same. Let’s take the tubular sterilizer as an example to briefly introduce the sterilizer:
1. General sterilizers also have different effects according to the PH value of the environment. Tubular sterilizers are applicable to many products, which can be used under the PH value of 1 to 14. They are suitable for the aseptic production of fresh milk, pasteurized milk, yoghurt, fancy milk, fruit juice, tea drinks, wine, ice cream, soymilk, jam, sauce products and other products. After sterilization, the products are in aseptic packaging, It can still be maintained for 3-6 months at normal temperature, and the cold chain is exempted;
2. Fully automatic computer control, touch LCD screen operation; The heat treatment process of the product is uniform, and the heat recovery rate is up to 90%
3. Efficient and rapid, instantaneous processing, maintaining the original flavor of the product, and using the high-tech PID temperature control system, the sterilization temperature is continuously recorded on the recorder in real time;
4. There is no contact point or sanitary dead angle in the tube of the tubular sterilizer, and the bellows forms high turbulence in the sterilization process, which has self-cleaning effect in the material flow process, saving the cleaning trouble.
