Vacuum Degasser

Vacuum Degasser for Fruit Juice Processing

A vacuum degasser removes entrained and dissolved gas from fruit juice, dairy products and other liquid foods before downstream processing. In a juice line, deaeration is commonly placed after homogenization and may be positioned before sterilization or filling, according to the process design. Reducing entrained air can help control foaming and limit oxygen exposure; the final effect depends on the product and operating conditions.

Juice Vacuum Degasser Structure and Working Principle

A typical assembly includes a stainless steel vacuum vessel, screw pump, vacuum pump and support frame. A float valve regulates liquid level. Juice enters through a nozzle, spreads into a thin film and flows along the vessel wall while reduced pressure allows gas to escape. A vacuum gauge supports monitoring; the conical outlet connects to the discharge pump. Adjustable feet and a hinged, sealed cover support installation and cleaning.

Vacuum Degassing Machine Features and Options

• The system can be configured with a degassing chamber, condenser and vacuum pump.
• Manual or automatic controls can be selected for the processing line.
• An optional gas-recovery unit can be assessed where the process calls for it.
• The equipment can operate in sequence with downstream sterilization equipment when the line design requires it.
• Degassing time and operating cycle should be set for the product, throughput and target gas removal.

How to Operate the Vacuum Degasser

Start the specified vacuum system and establish the process vacuum before feeding product. Monitor liquid level and feed rate through the controls and sight glass. Once the required vacuum is stable, use the discharge pump to transfer degassed product onward. Maintain the specified balance of vacuum, feed and discharge flow during continuous production. Follow the supplied operating manual for startup and shutdown.

Vacuum Degasser Cleaning and Maintenance

• Clean and sanitize the vessel before and after production according to the validated plant procedure. Where cleaning uses hot water at 90–95 °C and steam, confirm material, seal and utility compatibility before applying those conditions.
• Inspect sealing rings and replace aged or damaged parts.
• Check joints and seals for air leakage during operation.
• Check the vacuum gauge regularly and verify calibration as required by the plant.
