Hygienic Pressure Vessel Product Introduction
The hygienic pressure vessel is an advanced stainless steel storage and processing tank widely used in dairy, beverage, food, chemical and bio-engineering industries. It is manufactured from SS304 or SS316L with mirror-polished internal surfaces to meet strict sanitary standards. The system supports single, double and jacketed structures including dimple, full and coil jackets for heating or cooling functions. Designed for aseptic operation, it eliminates dead corners and supports CIP cleaning. With a capacity range from 50L to 20,000L, it is suitable for liquid storage, mixing and temporary buffering in modern industrial production lines requiring high hygiene and reliability.


Working principle
Step 1. Liquid is fed into SS304/SS316L hygienic pressure vessel
Step 2. Aseptic sealed structure prevents external contamination
Step 3. CIP system cleans internal tank automatically online
Step 4. Jacket system provides heating or cooling control
Step 5. Sensors monitor temperature and liquid level in real time
Step 6. Pressure system maintains stable storage conditions
Step 7. Output valves transfer liquid safely to next process stage
