Analysis of the sterilization method of fruit juice beverage production line

There are two types of beverage sterilization methods in fruit juice beverage production line: physical sterilization and chemical sterilization. Chemical sterilization methods use sterilants such as ethylene oxide, hydrogen peroxide, and sodium hypochlorite. Contemporary food sterilization methods are often physical sterilization methods due to the influence of chemical residues. Physical sterilization is divided into heat sterilization and cold sterilization.
  Heat sterilization is divided into microwave sterilization, far infrared heat sterilization, heat sterilization and dry heat sterilization. Cold sterilization is divided into freezing sterilization, ultraviolet radiation sterilization and ionizing radiation sterilization. Moist heat sterilization can be divided into high-temperature short-term sterilization, ultra-high temperature instantaneous sterilization and pasteurization.
  The so-called pasteurization is long-term low-temperature sterilization. The sterilization temperature is lower than 100°C, and the holding time is 30 minutes. High-temperature short-time sterilization (HTST): The sterilization temperature is generally 1000°C, just like milk, the HTST sterilization temperature is 85°C, and it is kept for more than 15 seconds. Ultra-high temperature instant sterilization (UHT), the sterilization temperature of 120°C lasts only a few seconds.
  HTST and UHT sterilization methods not only have high efficiency, but also preserve food structure, appearance, nutrition and flavor better than other sterilization methods. According to the sterilization method of fruit juice beverage production line, there are various types of beverage sterilization equipment developed accordingly, and the forms of processing materials are divided into the following three types:
   (1) Unpackaged dairy products, fruit juices and other materials are fluid beverages of fluid beverage sterilization equipment. Indirect and direct are the sterilization equipment that can be divided into processing such materials. It is an indirect type to heat-exchange and sterilize beverages with a plate and tube heat exchanger, and a direct type to spray steam directly into the material for sterilization.
   (2) Canned beverage sterilization equipment Canned beverages, bottled beverages and other packaging containers can be divided into pressurized sterilization equipment and atmospheric pressure sterilization equipment according to the sterilization temperature. Atmospheric pressure sterilization equipment is used to sterilize beverage products with a pH value of less than 4.5, and the sterilization temperature is below 100°C. The canning sterilization equipment designed according to the pasteurization principle belongs to this category. The pressure of the pressure sterilization equipment is greater than 0.1MPa, and it is generally carried out in a closed equipment, and the temperature is usually around 120°C. Atmospheric pressure sterilization equipment can also be divided into batch type and continuous type. According to the different heat sources used by the sterilization equipment, it can be divided into water heating sterilization equipment, direct steam heating sterilization equipment, continuous flame sterilizer, etc.
   (3) Physical sterilization equipment using electromagnetic waves is a promising sterilization equipment that uses physical radiation such as far-infrared rays, microwaves, and ultraviolet rays for heat sterilization.
