This relates to raw tofu designed device with a constant supply functions, such as raw water or groundwater The clean, filtered process is put together and soya beans in finely crushed bean grinder hygiene and stay clean can be efficiently crushed, ground beans that are structurally bean water and reverse upward flowing in the process of being separated by a busy to make a film and to improve the accuracy and stable operation of the grinding and separation operations of the beans dramatically. And soybean feeder 10 to be discharged to the lower side of the bean outlet 12 by a technical means for achieving this is added that the beans are designed to be put through the rotation operation input hopper 11 day 14, the number compartment day 35. The dose distribution is inclined arrangement plate 34 is quantified outlet 31 of the motor shaft is installed via the driving motor 41, 42 and the hopper shaft of the closing edge 15 and the dose distribution As the axis of the partition plate 36 is connected to a power source to operate beans passage opening 43 of the bean outlet 12 is beans evenly distributed by the quantitative distribution plate 34 from the swivel base (40) and quantitative divider 30 to be discharged, installed in the upper crushing plate 83 and the lower grinding plate (77) are each of a plurality of grinding blades on the inside, facing each other (84) (78) is a protrusion bean grinding barrel 71 and passing the axis of the upper grinding plate 83 is projected to the outside bean inlet (86) to be screwed into a fixed position while the lower pulverizing casing to the cover (75) crushing plate 77 is the bean grinding barrel 71 sphere 72, and the drive motor 20 is coupled rotatably to the crushing screw rotation shaft 81 of the beans is the amount thereof that is introduced through the distributor 30, the beans are crushed by a crusher crushing the lower plate (70 ) and the upper mill 101 and the lower millstone 108 bean water separation tube (91) engaging
