PCT No. PCT/EP92/01631 Sec. 371 Date Mar. 25, 1994 Sec. 102(e) Date Mar. 25, 1994 PCT Filed Jul. 17, 1992 PCT Pub. No. WO93/03217 PCT Pub. Date Feb. 18, 1993.An apparatus for preparing a stock wash liquor includes a stock liquor container with a stock liquor container comprising a tub-shaped bottom section and a top section which is hermetically mounted on the bottom section and is fitted with an integral suction fan designed to generate an underpressure or partial vacuum in the bottom section. A suction line leads out of the container and into a container of powder. The aim of the invention is to further develop a device of this kind so that stock liquor can be prepared from cleaning agent powder taken directly from its container without producing any dust, and the stock liquor thus prepared stored for feeding to industrial washing or cleaning machines. This is achieved by locating a secondary suction line end inside the stock liquor container at a point which is remote from the point of entry of a primary suction line into the bottom section. In addition, a fresh water line terminates in the container and has a water outlet aperture disposed so that the water is directed onto the stream of powder passing through the suction line. The container also has a stock liquor feed line which is operatively linked to a pump to permit liquor to be pumped from an inlet near the floor of the bottom section and out of the container.
