Under vacuum machine

Under-vacuum thermo-welding machine to treat products to be cooked inside thermo-sealing bags and carried with aluminum or stainless steel molds of proper dimensions.
The machine has a pre-loading conveyor belt with false bar, adjustable in height, to support the raised and stretched bag; a treatment tunnel with vertical sliding extremities doors; treated products receiving rolls or belt. The possibility to reach high sealing pressure makes the machine really reliable even in presence of wrinkles; there is moreover the possibility to have two parallel welding that minimize the risks coming from product residuals presence inside the bag.
The sealing bars length is of 1 meter and 40 or of 1 meter and 80, it depends on the model; the loading can be left or right.
The productivity depends from the molds and the bags measures, from the de-aeration cycle time (in function of the vacuum level, the pump type, the chose treatment cycle). It will be possible to insert inside the tunnel suitable injurious volume reducers to decrease the wished vacuum reaching time.
