The food packaging industry has dual requirements for production cycle and food safety. Traditional oil-lubricated vacuum pumps generate oil mist during operation, posing a risk of contaminating food, packaging materials, and the workshop environment. They also require regular oil changes and maintenance, affecting continuous production. Leynow oil-free vacuum pumps adopt an oil-free lubrication structure to prevent oil contamination from entering the vacuum system from the source, and have become the preferred configuration for multiple processes such as vacuum packaging, modified atmosphere packaging, skin packaging, blister packaging, and vacuum feeding.
Challenges Faced by the Industry
The requirements of food packaging production for vacuum systems are not just about "pumping fast", but more importantly, cleanliness, stability, and resistance to continuous operation. In practical applications, customers often encounter the following types of problems:
Risk of Oil Contamination
Oil-lubricated vacuum pumps generate oil mist during exhaust, which may contaminate food, packaging materials, and the workshop environment, affecting food safety.
Pumping Speed Cannot Keep Up with the Cycle
Food packaging production lines have fast cycles. Insufficient pumping speed will lead to decreased packaging efficiency, and substandard vacuum degree will affect sealing quality.
Unstable Continuous Operation
Food packaging equipment often needs to operate continuously for two or three shifts. Pump body overheating or vacuum fluctuations will directly affect the packaging finished product rate.
High Maintenance Costs
Vacuum pump oil needs to be replaced regularly, and the downtime for maintenance and consumable costs add up, affecting overall production efficiency.
Leynow Food Packaging Industry Solutions
Targeting the actual working conditions of the food packaging industry, Leynow provides overall vacuum solutions centered on oil-free vacuum pumps, forming a complete service closed loop from equipment selection and installation and commissioning to post-maintenance.
Clean and Oil-free Vacuum Acquisition Method
Oil-free vacuum pumps adopt a self-lubricating structure, and the inner wall of the cylinder is specially treated. They do not generate oil mist or exhaust gas, preventing lubricating oil from entering the vacuum system, meeting the cleanliness requirements of food, pharmaceutical, and daily chemical packaging.
Selection Solutions Matched to Packaging Cycles
Based on the packaging machine model, pumping speed requirements, packaging chamber volume, and production cycle, professional engineers provide selection suggestions to avoid efficiency and lifespan issues caused by "using a large pump for a small job" or "overloading a small pump".
Guarantee of Stable and Continuous Operation
For food packaging production lines operating continuously in two or three shifts, the heat dissipation and lubrication structures are optimized to reduce the risk of pump body overheating, maintain stable vacuum degree output, and ensure sealing and forming quality.
Full-cycle Service and Parts Guarantee
Providing installation and commissioning, regular follow-up visits, and maintenance contract services. Repair parts are Leynow original genuine parts. All repair projects come with a 12-month warranty to reduce unplanned downtime.
