Fruit Canned Food Sterilization Retort

The fruit canned food sterilization retort is specially designed for the sterilization of various fruit-based canned products, such as peach halves, pineapple slices, mixed fruit cocktails, and other similar items. It is suitable for a wide range of high-temperature resistant packaging materials, including metal cans, glass jars, and heat-resistant plastic containers.

This equipment is widely used in the food processing industry, particularly in fruit canning factories, to ensure efficient, uniform, and safe sterilization that preserves the natural flavor, color, and texture of fruits while extending shelf life.

• Loading the autoclave and injecting water
  First, load the product to be sterilized into the autoclave and close the door. Depending on the product’s filling temperature requirements, inject process water at the preset sterilization temperature from the hot water tank into the autoclave until the process set liquid level is reached. A small amount of process water can also be injected into the spray pipe through the heat exchanger.
• Heating Sterilization
  The circulation pump circulates the process water on one side of the heat exchanger and sprays it while steam is injected on the other side of the heat exchanger to heat the water to the set temperature. The control valve adjusts the steam flow to stabilize the temperature. Hot water is atomized and sprayed onto the product surface to ensure uniform sterilization. Temperature sensors and PID function control the temperature fluctuations.
• Cooling and Temperature Reduction
  After sterilization is completed, stop the steam injection, open the cold water valve, and inject cooling water into the other side of the heat exchanger to achieve temperature reduction of the process water and products inside the kettle.
• Drainage and Completion
  Drain the remaining water, release pressure through the exhaust valve, and complete the sterilization process.

The retort system reduces heat loss through a double-layer structure, and the circulating water is strictly treated and purified. The pressure sensor and regulating device precisely control the pressure. The automatic control system realizes full automation and also has functions such as fault diagnosis.
