Vacuum applications in food production

Packaging, drying, degassing and material conveying: start with the process before choosing a pump.

Vacuum packaging: review cycle time, chamber size, target pressure and the moisture entering the pump.

Drying and freeze drying: assess the required pressure and vapour load across the process, including the need for condensers and protection equipment.

Degassing and moisture removal: consider product characteristics, contamination risks and cleaning requirements.

Pneumatic conveying: assess material properties, transfer distance, air flow and separation equipment.

Compare rotary vane, dry claw, dry screw and side channel technologies against the actual duty point. Central systems can be assessed where several production lines share demand.
