Food
Non-Food
When bottling beverages, cosmetic or pharmaceutical products, the bottle is at first evacuated before being filled to make sure the product reaches the customer in good quality. Machines used for applications in the food industry are, in most cases, made from stainless steel.
Air and the oxygen that air contains have harmful effects on the quality and durability of fresh food. For this reason many processes need evacuation. The classic vacuum application in this field is vacuum packaging. Before sealing, a vacuum pump evacuates the air out of the packet. Vacuum pumps are used in numerous packaging machines for industrial use, e.g. Chamber machines, Forming machines, Carousel machines and Tray sealing machines.
For vacuum forming, an additional pump is needed at that part of the machine.
The surrounding pressure exerts a mechanical influence on the product that can greatly alter the external shape. For this reason, the MAP process has been the method of choice in many application areas. In this process, products are packaged in modified atmosphere and the oxygen removed. The product is enclosed in a blister package, placed in the vacuum chamber and evacuated. The modified atmosphere is then injected and the blister package and food are sealed with a protective film. Using this method the food retains its original shape and meats present a suitably red appearance to customers, even after extended storage.
Vacuum technology is used for the following applications: pellet drying, pellet conveying, extruder degassing, injection molding of performs, preform removal and handling, preform drying, blow molding of bottles, plasma treatment to deposit a barrier layer, pneumatic conveying of bottles, filling, labeling, Packaging and palleting, recycling
The film strips that are cut off are sucked into a container with our radial fan range CEVF. The collected film strips can be recycled.
Film tubes are inflated with compressed air and welded together to form cushions. These cushions can be used as protective filling material.
Blister packaging is often vacuum generated.

Chamber machines
Rolling machines
For vacuum forming, an additional pump is needed at that part of the machine.
When packing products, prior to sealing a vacuum pump would be used to evacuate the air from the packaging. Correct packaging provides the best transportation protection and ensures that products such as electronic parts, pharmaceuticals, etc, can be shipped to the customer aseptically and free of dust.
The L-Series is used for folding paper bags.
Vacuum packaging of clothes. The brand new clothes are shrink-wrapped to be able to charge trucks and containers to maximum capacity.
