PURPOSE:To make it possible to wash completely, by providing washing liquid- discharge holes in a stirring shaft at predetermined positions corresponding to area to be washed in the stirring tank, said holes being arranged so as to prevent a reverse flow of a liquid due to the pressure in the stirring tank. CONSTITUTION:In washing, a washing liquid is flown from an injector 11 through a liquid-feeding passageway 17 in a stirring blade shaft 2 to nozzle- fitting holes 4. From a liquid hole 10, the washing liquid enters a space 15 in a nozzle casing 5, and the pressurized washing liquid presses a valve 6 against a spring 7. As a result, the valve 6 is moved and a sheet surface 8 is opened, so that the washing liquid is dispersed in the inside of the stirring tank main body 1 and the inside of the tank can be washed. |
