Abstract
Abstract An apparatus for automatically manufacturing bean curd and at high production efficiency, free from sticking together of the cut pieces of bean curd and from the propagating of germs. This apparatus comprises a coagulating tank, a bean curd cutting device, a separating device and a packing device. Processes by these devices are carried out in hot water of the temperature at which various germs can not live so that bean curd in a germ-free condition can be produced. Unlike previous devices, both the cutting and packing devices function with hot water keeping the bean curd continuously covered. In this manner the integrity and cleanliness of the bean curd is maintained.
