Abstract
Abstract A machine for producing soybean curd comprises a conveyor having coagulating buckets, a device for filling a mixture of soybean milk and a coagulant into the buckets, means for heating the mixture in the buckets to coagulate the mixture into soybean curd, and a device for withdrawing the soybean curd from the buckets. A preheater for preheating the buckets to a temperature higher than the temperature of the mixture to be filled is disposed for a path of travel of the buckets at a position upstream from the filling device.
