2. What Is an Industrial Automatic Electric Vacuum Jacketed Cooking Kettle?

An Industrial Automatic Electric Vacuum Jacketed Cooking Kettle is a closed or semi-closed stainless steel vessel designed for cooking, mixing, concentrating, or processing materials under vacuum conditions while being heated through an external jacket system powered by electricity.

Core Definition:

A vacuum jacketed cooking kettle is a thermally controlled stainless steel vessel that combines vacuum pressure technology with electric heating and jacketed thermal distribution for efficient and uniform cooking or processing.

3. Working Principle of Vacuum Jacketed Cooking Kettle

The operation of this equipment is based on three core technologies:

• Vacuum environment control

• Electric heating system

• Jacket heat transfer system

Step-by-step process:

1. Material Loading

Raw materials such as liquids, sauces, pastes, or semi-solid mixtures are loaded into the kettle.

2. Vacuum Creation

The system removes air from the kettle, creating a low-pressure environment.

3. Heating Phase

Electric heating elements heat the jacket layer, transferring heat evenly to the inner vessel.

4. Cooking or Concentration Phase

Under vacuum conditions, the boiling point decreases, allowing gentle cooking at lower temperatures.

5. Mixing (Optional)

Agitators ensure uniform heat distribution and prevent material sticking.

6. Temperature and Pressure Control

Sensors continuously regulate vacuum pressure and temperature.

7. Discharge

Final processed material is discharged through sanitary valves.

4. Key Features of Industrial Vacuum Jacketed Cooking Kettle

• Fully automatic electric heating system

• Vacuum-controlled cooking environment

• Stainless steel hygienic structure (SS304 / SS316)

• Jacketed heating for uniform temperature distribution
