The present invention relates to a vacuum packaging machine for vacuum sealing by putting food into a vacuum packaging bag, removing air from the vacuum packaging bag, and sealing an open portion of the vacuum packaging bag, and a system for controlling the vacuum packaging machine. The vacuum packaging machine includes a housing (10), a hood (20) and a separation unit (60). The housing (10) has a cover (11b) with a rubber packing (12) attached to a border thereof and an outlet (110b) formed therein, and a heater (16) for sealing a vacuum packaging bag. The hood (20) is hingedly connected to the housing (10) to selectively open and close a top of the housing (10), and has a rubber packing (22). The separation unit (60) communicates with the outlet (110b) through a communicating member and is connected to a vacuum pump. The vacuum packaging machine forms a vacuum through the vacuum pump when the rubber packings (22 and 12) of both the hood (20) and the housing (10) come into contact with each other. The separation unit (60) communicates with a filter means (80) having a filter casing (82) for filtering impurities or oil contained in the vacuum packaging bag, a filter (84) inserted into the filter casing (82) to remove the impurities, and a filter casing cover (86).
Disclosed herein is a vacuum sealer, which exhausts air from a thermal adhesive vacuum bag containing products and then heats and seals the open end of the vacuum bag. The vacuum sealer includes a lower body. An upper body is pivotably mounted to the lower body in such a way as to engage with the lower body. A heater is installed in either or both the lower body or/and the upper body, and heats and seals a vacuum bag. A vacuum space creating member is installed in either or both the lower body or/and the upper body, and isolates an end of the vacuum bag which is evacuated from an exterior, thus creating a vacuum space. A vacuum pump is coupled via a tube to an exhaust hole communicating with the vacuum space created by the vacuum space creating member.
