What is a water spray sterilization retort?

As one of the food sterilization retort, the water spray sterilizer realizes the possibility that a small amount of process water can be recycled during the sterilization process. After an efficient heat exchange, the hot water is sprayed to the surface of the food for sterilization from the nozzle.

In the sterilizer, the heat is evenly distributed, and there is no sterilization dead angle.

The water is heated and cooled through the heat exchanger, and the heating and cooling speed is fast, which can efficiently and comprehensively sterilize the product.

Water Spray Food Retort Structure and Features

  1. Water spray retort consists of horizontal tank, heat exchanger, circulating water pump, cooling water pump, pipeline and various valves and automatic control system.
  2. There are water showers with nozzles both for side spray and top spray. The softened water for sterilization is recycled.
  3. The hot water sprayed through the spray nozzles contacts the surface of the food, which disperses the cold air mass in the retort. The sprayed water mist fills the entire retort space and carries the same temperature, therefor, the temperature distribution in the retort is uniform and free of dead angle.
  4. The temperature rise and cooling process by means of the plate heat exchanger is divided into several step curves, the center and surface temperatures of the sterilization basket are consistent uniformed.
  5. Pressure, temperature and sterilization time are all automatically controlled, which is more precise than manual control.
