PURPOSE:To enable effective squeeze without twisting a sponge roller by pressurizing from one end to another end of the sponge roller, and repeating this operation. CONSTITUTION:A pressure roller unit 40 is formed by annularly arranging plural pressure rollers 41. The pressure roller unit is allowed to run back and forth by the chain feed mechanisms 30 and 30 of a running means. The sponge roller P is pressurized from one end to another end of the sponge roller P. By repeating this operation, liquid permeated in the sponge roller P is squeezed. Consequently, human labor can be reduced, a sanitary control can be improved, and efficiency in squeezing can be made better. |
