SEMI-AUTOMATIC LINE FOR PACKAGING FOOD PRODUCTS IN VACUUM AND/OR THERMALLY SHRUNK BAGS

摘要

The present invention relates to a semi-automatic line for packaging food products in vacuum and/or thermally shrunk bags. The claimed line comprises a vacuum bag packaging equipment (1) and a tank (3) for the thermal shrinkage by immersion into hot water, and also a system for conveying the packets from one equipment to another equipment, which comprises a roller mobile platform (7) and a roller conveyor (2), the actuation of a cover (6) and also the actuation of a sealing rod (8) and of the mobile platform (7) being ensured by some pneumatic cylinders (C, Cand C) actuated by the difference of pressure between the atmospheric pressure and the pressure created by a vacuum pump, some electric valves (EV, EV, EV, EV, and EV) being also controlled by creating a depression, the control system developed around a processor containing some stabilized supplying sources for some position sensors (S, S, Sand S), a processor, some electric valves (EV, EV, EV, EV, and EV), a heat sealing resistor, a processing module, a digital display module, some controlling elements consisting of sensors (S, S, Sand S), electric valves (EV, EV, EV, EV, and EV), the vacuum pump, the heat sealing resistor and also a keyboard for setting the initial parameters.
