Industrial Vacuum Deaerator for Juice, Sauce & Dairy Processing
The EasyReal vacuum degassing unit works as a key step in juice, beverage, and dairy processing lines. A vacuum chamber reduces the pressure inside, which makes gases in the product rise and leave quickly. The degassed liquid then moves to the next section with stable quality.
Inside the chamber, a high-vacuum pump maintains precise negative pressure levels. A built-in aroma recovery condenser captures volatile aromas, returning them to the main stream so the drink keeps its natural flavor.
All contact surfaces use food-grade SUS304 or SUS316L stainless steel. The design follows EHEDG and FDA hygienic standards. CIP and SIP connections make cleaning and sterilizing automatic. Operators control everything through a PLC touch screen, where setpoints for flow, temperature, and vacuum are saved as recipes.
Each vacuum deaerator is available from 500 L/h to 50 000 L/h. The compact skid fits easily into existing lines, with minimal floor space and short installation time.
EasyReal builds industrial vacuum deaeration systems for fruit and vegetable juice, tea drinks, plant milk, dairy, and flavor-sensitive beverages.
Common uses include:
• Fruit juice before sterilization(apple, mango, pineapple, orange, tomato).
• Tea, coffee, and herbal infusions before hot filling.
• Milk and plant-based drinks to reduce foam and oxidation.
• Fermented drinks and enzyme liquids before cooling or storage.
Removing air improves product color, prevents foaming during filling, and extends shelf life. Factories use EasyReal’s vacuum degassing unit to achieve smooth operation at high throughput. Consistent oxygen removal leads to stable taste, fewer returns, and higher customer satisfaction.
Every liquid behaves differently under vacuum. EasyReal’s engineering team designs each vacuum deaerator to match viscosity and flow rate.
A typical system includes:
• Product inlet pump with variable-frequency drive (VFD) for flow control.
• Vacuum pump，condenser.
• Discharge pump with level control for continuous flow.Process safety is critical. A transparent sight glass lets operators check product condition. All sensors (vacuum, temperature, conductivity) connect to the PLC for smart alarms and trend recording.
Choosing the proper vacuum degassing unit depends on several factors:
1. Capacity: Different capacity will need different size buffer tank and product pump
2. Viscosity: Different viscosity product will affect the choice of product pump
3. Integration: connect sterilizer to realize inline degassing function.
EasyReal offers pilot tests and CFD-based simulations to verify oxygen-removal efficiency before final sizing. Engineers calculate vacuum volume, nozzle design, and residence time to guarantee full degassing without product loss.
Below is a simplified process for industrial juice and beverage degassing:
Feed → Vacuum Chamber → Degassing → Aromatic Substance Recovery → Discharge → Next Processing Stage
1. The feed pump delivers the product to the vacuum chamber,
2. The liquid enters the vacuum chamber through a spray nozzle.
3. Under vacuum negative pressure, non-condensable gas overflows.
4. A condenser collects vapor and volatile aromas.
5. The discharge pump transfers the degassed liquid to the sterilizer or filler.
Each EasyReal deaerator includes automatic vacuum control, condensate removal, and CIP cleaning. Operators monitor performance on the HMI screen. The control system logs vacuum level, and product flow in real time.
The EasyReal vacuum deaerator integrates several essential units to deliver stable, oxygen-free liquid processing.
1. Vacuum Chamber
The vacuum chamber is the core of the system. It operates under −0.05 to −0.09 MPa and provides a wide internal surface for gas release. A glass inspection port allows visual monitoring during operation.
2. Vacuum Pump System
Maintains steady negative pressure.
3. Aroma Recovery Condenser
Volatile aroma compounds often evaporate under vacuum. The condenser captures and returns them to the main liquid flow, keeping natural flavor intact. This feature is essential for high-value fruit juices and teas.
4. CIP / SIP Connections
Built-in spray balls allow complete internal cleaning. Operators can start automatic CIP cycles using hot water and alkaline detergent. The system integrates with the plant’s central cleaning line, reducing downtime between production runs.
5. Instrumentation and Control
Each vacuum degassing unit includes pressure transmitters, temperature sensors, and level detectors. The PLC collects real-time data and displays trends on the HMI. Alarm limits and interlocks protect against product loss or pump overload.
Together, these components create a fully automated and hygienic system with minimal operator intervention. The result is uniform product quality, higher uptime, and lower operating cost.
The EasyReal vacuum deaerator handles a wide range of raw materials and beverage bases.
Input flexibility:
• Fresh or concentrated fruit juice
• Reconstituted puree with fiber or pulp
• Plant-based milks (soy, oat, almond)
• Tea or herbal extract solutions
• Milk and dairy mixtures
Output applications:
• NFC juice (Not-From-Concentrate)
• Juice concentrate lines with aroma recovery
• Ready-to-drink beverages for hot-fill or cold-fill
• Dairy and plant-based drinks before sterilization
• Syrup, enzyme, or fermentation bases requiring oxygen control
Each product type benefits differently. Juices keep bright color and clear flavor. Tea extracts maintain aroma. Milk products avoid air bubbles that disturb filling machines.
Operators can switch between materials in under 30 minutes using automated CIP cleaning. This flexibility supports seasonal production without expensive changeovers.
EasyReal ingrate the control system of vacuum deaerator into the complete line or equip one seperate control system.
The touchscreen HMI allows full process control and record-keeping:
• Recipe management: Save and recall setpoints for temperature, vacuum, and flow.
• Real-time monitoring: Display pressure, liquid level,pump flow rate etc.
• Alarm & interlock logic: Automatic shutdown prevents overflow or vacuum loss.s.
• Remote support: Optional Ethernet module allows EasyReal engineers to assist online.
This system helps operators maintain consistent results and shortens training time. Trend curves show process stability, so supervisors can optimize production without guesswork.
Smart controls also integrate with upstream preheaters and downstream pasteurizers. The complete line operates in sync, which reduces waiting time and energy consumption.
EasyReal supplies complete turnkey solutions from design to commissioning.
The project scope includes:
1. Process design: Capacity calculation, P&ID diagram, and equipment selection.
2. Pilot testing: Oxygen-removal verification using customer raw materials.
3. Fabrication & assembly: All skid units pre-tested in EasyReal’s Shanghai factory.
4. Installation & commissioning: On-site supervision, parameter setup, and vacuum calibration.
5. Training & documentation: Operator manuals, cleaning procedures, and maintenance schedules.
6. After-sales service: Spare-parts stock, remote diagnostics, and yearly technical inspections.
EasyReal’s experience in juice and beverage processing ensures each vacuum degassing unit integrates smoothly into existing plants. Customers in more than 40 countries trust EasyReal for reliable degassing and flavor protection.
