Apparatus for the vacuum packaging of food

An apparatus for the vacuum packaging of food, which comprises a base structure which defines a vacuum chamber which is configured to be connected to a vacuum pump, further comprising, between said vacuum chamber and said vacuum pump, at least one air filtration device which has variation means configured for varying at least one thermo-fluid dynamics parameter of a flow of air extracted from said vacuum chamber by said vacuum pump, to enable the elimination, from the air extracted from said vacuum chamber, of water, biochemical liquids, and biological materials, wherein said filtration device comprises an enclosure which has at least one inlet which communicates with said vacuum chamber and at least one outlet which communicates with said vacuum pump, said variation means being interposed along the path of the flow of air inside said enclosure from said inlet to said outlet, wherein at least one air conveyance channel is defined in said enclosure and extends from said inlet to said outlet, along said conveyance channel there being at least one condensation chamber for condensing the water contained in the flow of air that passes through said conveyance channel, said cooling means comprising means configured for circulating a cooling fluid, in a heat exchange relationship with said condensation chamber, at least one discharge port for the water condensed and separated from the flow of air passing through said conveyance channel being defined in said enclosure.
