The main functions of sterilizers include food sterilization, sterilization and disinfection, cooking ingredients, heat preservation and steaming, etc. Sterilizers can kill bacteria and viruses in food under high temperature and high pressure to ensure that food reaches commercial sterility, thereby extending the shelf life of food. In addition, sterilizers can also be used to sterilize and disinfect utensils, linens, baby bottles and other items to improve hygiene standards and ensure people's health and safety. For some ingredients that need to be cooked before they can be eaten safely, such as large pieces of meat and eggs, sterilizers can quickly cook these ingredients to ensure the safety of food. At the same time, sterilizers also have the functions of heat preservation and steaming food, so that food remains fresh and nutritious, meeting people's needs for food taste and nutrition.
The working principle of the sterilizer is to heat the food sealed in the container through a closed and pressurized heating process. During the sterilization and cooling process, some systems use overpressure technology to improve the sterilization efficiency by applying pressure exceeding the set threshold. For example, a sterilization system using 25-35psig can operate at higher temperatures and is suitable for a variety of containers, such as semi-rigid plastic containers with heat-sealed lids or bimetallic seam can ends, soft bags, metal trays, cardboard containers, and glass jars.
Different types of sterilizers include fully automatic sterilizers, vertical sterilizers, horizontal sterilizers, etc. Fully automatic sterilizers use advanced technologies such as PLC fully automatic linear control to achieve precise control and management of the sterilization process, improving sterilization efficiency and energy saving. Hot water rotary sterilizers use high-temperature and high-pressure hot water for high-temperature rapid sterilization, which is suitable for the sterilization of various beverages and foods, especially for the sterilization of high-viscosity and large-volume products. Stainless steel sterilizers use saturated steam as the heating medium and perform back pressure operation by supplementing compressed air, which is suitable for sterilization of different packages and different foods.
