Applicable Product Range and Advantages of Steam Sterilization Kettles

Steam sterilization kettles are widely used for various packaged foods that require long-term shelf stability, typically operating at temperatures between 108°C and 135°C.

I. Applicable Product Range

Steam sterilization kettles are primarily suitable for the following product categories:

1. Canned Foods: Examples include meat products such as luncheon meat, sardines, and canned beef; beverages, fruits, and vegetables like coconut juice, walnut milk, and asparagus cans; as well as condiments like sweet bean sauce and tomato sauce. This equipment is ideal for processing low-acid foods (e.g., most vegetables, meats, aquatic products), as its high-temperature sterilization process effectively eliminates pathogens like Clostridium botulinum.

2. Bottled & Glass Jar Products: These kettles are suitable for products packed in glass jars, such as fruits, vegetables, and sauces. The process ensures container seal integrity without chemical residues. However, precise pressure control during the cooling phase is crucial to prevent glass breakage.

3. Products in High-Temperature Resistant Packaging: They are applicable to metal packaging like tinplate and aluminum cans, as well as special foods like congee with eight treasures and salted duck eggs. Steam provides uniform heat penetration through the containers, helping to maintain the product's texture and flavor. For packages prone to deformation (e.g., semi-rigid plastics, flexible pouches), an "overpressure" function can be used to counteract internal pressure and prevent container distortion.

II. Key Technical Advantages

The core technical advantages of steam sterilization kettles are evident in three main areas:

• Uniform Heat Distribution: The dynamic circulation of saturated steam ensures highly consistent temperature throughout the sterilization chamber, effectively eliminating cold spots and achieving thorough sterilization. This is particularly effective for solid and semi-solid products.

• Energy Efficient & Eco-Friendly: Steam serves as a direct and highly efficient heating medium. Compared to traditional water-bath sterilization methods, steam retorts consume minimal water, significantly reducing both energy and water consumption.

• Precise Control: Equipped with fully automated PLC (Programmable Logic Controller) systems, these kettles allow for precise regulation and monitoring of parameters such as temperature, pressure, and time. This ensures reproducible sterilization results and high product quality, facilitating compliance with strict food safety regulations.
