Food sterilization equipment Manufacturer: What is high-temperature sterilization equipment like?

　　Food sterilization equipment manufacturer: High‑temperature sterilization is a traditional packaging‑based sterilization method, typically involving treatment at temperatures between 100°C and 130°C. It is primarily suited for low‑acid foods with a pH below 4.5. This method boasts a broad range of applications, making it ideal for sterilizing milk, fruit juices, meat products, seafood, and various other food items. However, the packaging materials must exhibit excellent barrier properties and sufficient resistance to high‑temperature processing.

　　The main types of high-temperature food sterilization equipment are:

　　Food sterilization equipment manufacturer: Steam sterilizers use steam as the heating medium and heat directly. A mechanical system maintains a mixture of steam and air, circulating it throughout the sterilization chamber. During the sterilization process, the presence of air in the chamber can create cold spots, resulting in uneven heat distribution.

　　Spray sterilization pot

　　This method is divided into top immersion, side spraying, and full-spray. It employs nozzles and spray tubes to apply hot water to the food surface, ensuring uniform temperature and eliminating dead zones.

　　Advantages of the spray‑sterilization pot: 1) It employs indirect heating and cooling, with the cooling water kept separate from the process water, thereby preventing secondary contamination of food and eliminating the need for water‑treatment chemicals. 2) It reduces steam consumption by directly mixing the sterilizing mist with the product inside the sterilization chamber, accelerating the cooling process. 3) Pressure is easy to control; throughout the production process, the pressure can be continuously adjusted to accommodate changes in the internal pressure of the product packaging, minimizing package deformation—making it particularly well suited for products packaged in air‑filled containers.

　　Tank-type sterilization pot

　　Food sterilization equipment manufacturer: The water‑bath sterilizer directly injects steam to heat the water in the hot‑water tank to a preset temperature. As the process product is fed into the processing vessel, the process water inside the vessel continues to circulate, with heat supplied by a steam‑water mixer for sterilization. During sterilization, the food is fully immersed in hot water, and pressure combined with a pump ensures continuous circulation, resulting in relatively uniform heat distribution.

　　Advantages of a water‑bath sterilizer: 1) It employs a dual‑loop hot‑water circulation system to preheat the water in the heating tank to the required sterilization temperature, thereby shortening the sterilization cycle and boosting productivity. 2) The temperature inside the sterilization chamber remains stable throughout every stage of the sterilization process.

　　Food sterilization equipment manufacturer: What is microwave sterilization equipment like?

　　Food sterilization equipment manufacturer: Microwave sterilization is a method that, while processing food, leverages both the thermal and specific‑heat effects of microwaves to induce structural changes in proteins and bioactive compounds within microorganisms, thereby delaying their growth and leading to cell death, ultimately achieving food sterilization and preservation.

　　 Food sterilization equipment Manufacturer: Microwave sterilization is short in duration and fast in speed. It works by directly exposing food and microorganisms to microwave energy, with both thermal and specific‑heat effects combining to achieve rapid heating and sterilization, significantly reducing processing time; the typical sterilization cycle for most products is 3–5 minutes. Microwave sterilization is a form of pasteurization that, compared with conventional heat‑based methods, can deliver the required level of microbial inactivation at lower temperatures and in shorter times. Typically, effective sterilization can be achieved at temperatures between 75°C and 80°C, helping to preserve the nutritional content and traditional flavor of the food.
