Autoclaves & Sterilization Retorts
Providing high-temperature thermal sterilization at ~121°C to extend canned food shelf life and satisfy strict safety standards.
Autoclaves and sterilization retorts are high-temperature, pressurized vessels used for thermal sterilization after packaging. Also known as retort sterilizers, they are suitable for canned meat, poultry, fish, egg products, and certain canned vegetables that require high-temperature sterilization.
The sterilization process is typically carried out at around 121°C, helping ensure stable and safe processing for canned food production lines.
- Principle: Steam is used directly as the sterilization medium.
-
Applications
- Metal containers: Tinplate cans, such as luncheon meat cans and canned fish
- Flexible packaging: Aluminum foil pouches and high-temperature retort pouches for lightweight products
- Glass containers: Not recommended
- Plastic containers: PP bottles are not recommended
- Other sterilization applications: Medical waste, edible fungi, wood, soil, and related materials
Main Features: A small amount of circulating process water is used as the sterilization medium for spray sterilization. The temperature is gradually increased and decreased through a heat exchanger, supporting controlled heating and cooling during the sterilization process.
- Principle and Features: Water immersion sterilization is used to heat and sterilize packaged products evenly during the retort process.
-
Applications
- Plastic containers: PP bottles, such as coconut milk bottles and soy milk bottles; HDPE bottles
- Flexible packaging: Aluminum foil pouches, transparent pouches, and vacuum pouches, including food pouches, condiment sauce pouches, wet pet food, corn, chicken feet, dried tofu, meat products, and related packaged foods
