Foods

Meat, vegetables, and prepared foods are vacuum-packed or rapidly cooled in a vacuum to retain their quality for a more extended period. We offer the P series oil-sealed rotary piston vacuum pumps, which are rugged and resistant to repeated pump down from atmospheric pressure, and the W series liquid ring vacuum pumps, which are suitable to pump gases containing water vapor.

Vacuum freeze-drying is used to dry foods while preserving heat-sensitive components. For this process, we offer the P series oil-sealed rotary piston vacuum pumps, the W series liquid ring vacuum pumps, and the RD series roots vacuum pumps for boosting pumping speeds.

Vacuum concentration and vacuum distillation are used to concentrate or separate heat-sensitive components. Since these processes involve pumping gases that contain large amounts of water vapor, we offer steam ejectors and combinations of the W series liquid ring vacuum pumps and the RD series roots vacuum pumps.
