The Yasaki ZJ-VM400B2 is a commercial benchtop chamber vacuum sealer that removes air from the sealing chamber and heat-seals bags in a single automatic cycle, preserving food up to three to five times longer and preventing product discolouration. Its stainless-steel chamber measures 280 x 380 x 75mm and runs a complete pack cycle in 10 to 30 seconds. Built for medium to large venues, the unit pairs a stainless-steel housing and chamber with a high transparent lid so operators can watch each seal complete. A 20 m³/h vacuum pump draws a deep vacuum quickly, while twin 400mm seal bars close two bags per cycle to keep pace during batch prep.
