Abstract
A vacuum apparatus for industrial hide driers with multiple beds (2) includes a circuit with an open end (17) having arranged in a series: a vapor manifold (7) for each bed; a first condenser (8) inserted in each manifold; a first condensate separator (10) at the output of the various condensers (8); a main vacuum pump (16) to gradually reduce the absolute pressure in the circuit to a first upper value (P.sub.s). A particular feature of the system consists of the fact that it has a secondary aspiration device (19) which is arranged upstream of the main vacuum pump (16) to operate in series to this pump when the first value of the absolute pressure (P.sub.s) is reached, so as to further reduce the pressure of the circuit to a second lower value (P.sub.i). The upper value (P.sub.s) of the absolute pressure is 40 to 100 mbar; the second lower value (P.sub.1) of the absolute pressure is 15 to 1 mbar. The device (19) is a high-capacity, low-head blower.
