Food Packaging Applications – Oil-Lubricated Vacuum Pumps & Oil-Free Compressors

In modern food packaging lines, vacuum and compressed air systems play a vital role in product preservation, safety, and efficiency.
UNi-CROWN Industrial specializes in oil-lubricated rotary vane vacuum pumps and oil-free compressors, providing high-performance air solutions for vacuum packaging, tray sealing, thermoforming, MAP systems, and pneumatic automation.

Our RV Series rotary vane vacuum pumps offer high pumping speed, stable vacuum, and long service life — ideal for continuous operation in high-throughput packaging lines.
In addition, our oil-free air compressors deliver clean, dry compressed air for control valves, actuators, and other pneumatic devices in packaging systems.

Applications: Vacuum packaging machine, Sealing machine, Filling machine, Vacuum receiver, Labeling machine, Vacuum oven.

Food Packaging Applications
Vacuum Packaging Machines
In vacuum packaging, air is removed from the bag or tray before sealing to preserve freshness and extend shelf life.
The RV Series oil-lubricated rotary vane pumps provide strong suction, fast evacuation, and stable end-vacuum, ensuring reliable sealing and uniform vacuum levels in every cycle.
Recommended models: RV-016, RV-40N, RV-63, RV-100

Tray Sealing & Thermoforming Machines
Thermoforming and tray sealing machines require powerful vacuum performance for forming film, removing trapped air, and achieving perfect seals.
The RV Series pumps maintain constant negative pressure for deep forming molds and high-speed sealing, ensuring wrinkle-free, leak-proof packaging.
Recommended models: RV-63, RV-100, RV-160

MAP (Modified Atmosphere Packaging) Systems
During MAP packaging, vacuum pumps remove residual air before the chamber is backfilled with nitrogen or carbon dioxide.
Consistent vacuum levels from the RV Series allow precise gas mixing ratios, helping preserve color, texture, and flavor for meat, seafood, and ready-meal products.
Recommended models: RV-100, RV-160, RV-200

Vacuum Drying & De-aeration
Vacuum systems are used in food dehydration, coffee bean drying, and flavor extraction to lower the boiling point of moisture and shorten drying time.
Oil-lubricated pumps with high vapor-handling capability are ideal for these applications, delivering steady vacuum under moisture-rich conditions.
Recommended models: RV-63, RV-100, RV-160 (with moisture separator or condenser)

Vacuum Conveying & Powder Handling
Vacuum pumps transfer powders, grains, and fine materials through sealed pipelines, maintaining hygiene and dust control in food production areas.
The RV Series provides continuous vacuum flow for short- to medium-distance conveying systems.
Recommended models: RV-63, RV-100, RV-160

Labeling, Capping & Holding Systems
Vacuum suction supports label positioning, bottle holding, and cap placement during packaging.
Compact oil-lubricated or oil-free pumps ensure stable and clean suction for automation lines.
Recommended models: RV-40N, RV-63, UN-40V (oil-free option)

Compressed Air Applications
Pneumatic Control & Automation
Food packaging machines use compressed air to drive cylinders, sealing bars, and pick-and-place systems.
UNi-CROWN oil-free compressors provide clean, dry air to ensure smooth pneumatic operation without contamination risks.
Recommended models: UN-90P, UN-120P, Q AIR Series

Filling & Dispensing Systems
Clean compressed air is essential for actuating valves and dosing pumps in liquid filling and bottling machines.
Oil-free compressors from the UN and Q AIR series deliver stable pressure and low noise, suitable for hygienic packaging environments.
Recommended models: UN-90P, UN-120P, Q AIR Series

Mixing, Aeration & Agitation
In mixing or fermentation processes, small oil-free compressors supply consistent airflow to maintain uniform blending or gentle aeration.
Recommended models: UN-80P-OXY, UN-90P, Q AIR Series

Scalable Vacuum System Solutions
Small & Medium Food Packaging Lines

Compact RV pump systems or dual-pump modules provide reliable vacuum for packaging machines, sealing stations, and thermoformers with automatic switching control.
Recommended models: RV-63, RV-100

Centralized Vacuum Systems for Large Factories
Multi-pump vacuum stations with buffer tanks and PLC control panels supply stable vacuum to several packaging and MAP lines simultaneously.
Recommended configuration: RV-100×2 + 1000 L Vacuum Tank

Extended Applications
UNi-CROWN vacuum and air systems are also applied in snack packaging, coffee production, dairy processing, seasoning, and frozen-food packaging lines.
Their robust design, stable performance, and low maintenance make them ideal for continuous 24/7 operation in modern food factories.
