During high‑temperature food sterilization, the primary target of the retort is Clostridium botulinum, which produces a toxin capable of causing fatal harm to humans. Naturally, the higher the temperature, the shorter the survival time of pathogenic microorganisms. Therefore, when sterilizing meat products, we typically maintain a carefully controlled temperature; excessively high temperatures will inevitably have an adverse impact on the food’s flavor.

　　During the high-temperature sterilization of food, Sterilization pot The primary target is Clostridium botulinum, which produces a toxin that can be fatal to humans. Of course, the higher the temperature, the shorter the pathogen’s survival time. Therefore, when sterilizing meat products, we typically keep the temperature within an appropriate range; excessively high temperatures will inevitably have an adverse effect on the food’s flavor.

　　Sterilization pot sterilization mode:

　　1. Hot-water circulation sterilization:

Sterilization pot

　　During sterilization, all food in the sterilizer is immersed in hot water, ensuring relatively uniform heat distribution.

　　2. Steam sterilization:

　　After the food is loaded into the sterilization pot, water is not added first; instead, it is heated directly with steam. This is because, during sterilization, cold spots can form in the air inside the pot, resulting in uneven heat distribution.

　　3. Water-spray sterilization:

　　Hot water is sprayed onto the food through nozzles or spray pipes. During the sterilization process, mist‑like, wave‑shaped hot water is directed onto the product surface via nozzles mounted on both sides or the top of the sterilizer, ensuring uniform temperature with no dead zones and rapid heating and cooling. This enables fast, stable sterilization of products inside the sterilizer, making it particularly well suited for sterilizing soft‑packaged foods.

　　4. Steam‑mixed sterilization:

　　This sterilization method ingeniously combines steam and water spray: a small amount of water is added to the chamber to meet the requirements of continuous spray circulation, while steam is introduced directly into the vessel, enabling short‑cycle, energy‑efficient, and environmentally friendly sterilization of specialized products.

　　For a food processing plant, high-temperature sterilization of food is extremely important! It has the following two characteristics:

　　1. Single‑pass: High‑temperature sterilization is carried out in one continuous step from start to finish, with no interruptions; food must not be subjected to repeated sterilization.

　　2. Abstract of sterilization efficacy: Sterilized food cannot be visually inspected, and bacterial culture tests require a week, making it impossible to verify the sterilization performance of every batch of sterilized products.

　　Based on the aforementioned characteristics, this necessitates that users of sterilization kettles:

　　1. First, it is essential to ensure that the entire food processing chain is hygienic and uniform, so that each bag contains an equal initial microbial load prior to packaging, thereby guaranteeing the efficacy of the prescribed sterilization regimen.

　　2. Secondly, sterilization equipment with stable performance and precise temperature control is required, and the established sterilization protocol must be executed reliably and with minimal deviation, ensuring standardized and consistent sterilization outcomes.
