Types of Water Spray Retort
The water spray retorts produced by our company mainly include the following types

Automatic Water Spray Autoclave
Water Spray Retort Canning Olive Retort Food Canning Rotary Sterilization Food Sterilizer Retort Machine is mainly composed of the horizontal body, the heat exchanger, the circulating water pump, the pipeline and various valves, as well as the automatic control system.

Rotary Type Water Spray Retort
Automatic rotary type water spray retort is widely used in the sterilization process of filling porridge/Congee, fruit milk, beverage, sauce and other products, especially for high viscosity and large capacity food. During the sterilization process, the rotating cage continuously rotates to ensure that the sterilized product does not layer or settle within its shelf life.

Shake Type Water Spray Retort
The shake type water spray retort is a type of oscillating sterilizer that allows the product to move back and forth, thereby accelerating heat transfer inside the packaging, reducing heating and heat penetration time, and improving the taste of food.
Advantages of Water Spray Retorts
Precise temperature control
Water spray retorts allow for precise temperature control, which is crucial for heat treating different types of materials. This precision allows for consistent results and can help reduce the risk of defects.
Faster heat-up and cool-down times
Water spray retorts typically have a faster heat-up and cool-down time compared to other heat treatment methods. This can be an advantage when processing large quantities of materials or when working with materials that require quick temperature changes.
High temperature capacity
Water spray retorts are capable of handling higher temperatures than some other heat treatment methods. This can be useful for heat treating materials that require higher temperatures for the desired outcome.
Easy to use and operate
Water spray retorts are relatively easy to operate, and require minimal maintenance. This makes them a cost-effective option for heat treating materials in many industries.
Wide Range of Applications
Water spray retorts can be used to treat a wide range of materials, including chemicals, plastics, and organic compounds.

Operation Steps of Water Spray Reactor
Loading
Canned or packaged foods are systematically loaded into the retort chamber.
Sealing
The chamber is hermetically sealed, creating an airtight environment.
Heating & Sterilizing
Unlike traditional methods where cans might be fully submerged in water, the Water Spray Retort uses steam to heat the water, which is then sprayed onto the cans. This technique ensures uniform temperature distribution, effectively killing off any potential pathogens.
Cooling
Post-sterilization, the retort introduces cool water in a spray form to bring down product temperatures, thus preventing overcooking and ensuring the desired product quality.
Unloading
Upon completion, the chamber’s pressure is normalized, and products are readied for unloading.
Packaging and Shipping
|
Packaging |
Using wooden boxes, tarpaulins or other packing methods to meet customer requirements. Regardless of the packaging method, we will reinforce the retorts and their accessories before delivery to ensure that the retorts will not receive damage during transportation. |
