Abstract

Abstract A process for producing bean curd comprising the steps of cooling soybean milk and bittern individually to below the coagulating temperature of the milk, mixing the cooled milk and bittern together and filling the mixture into buckets, coagulating the mixture in the buckets by heating, and withdrawing the coagulated milk from the buckets and detwatering the coagulated milk to obtain formed bean curd. An apparatus for practicing the process comprises a mold box and a pressing closure each having in a required portion a multiplicity of holes not passing the coagulated milk therethrough but permitting the water contained in the coagulated milk to pass therethrough.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 161 words
An apparatus for producing bean curd, by coagulating a mixture of soybean milk and bittern producing coagulated soy bean milk, comprising: an intermittently driven bucket conveyor having buckets stoppable one after another at a filling station; a filling device having a delivery opening directed downward to oppose each of the buckets from above when the bucket is at rest at the filling station, a steam chamber enclosing at least the delivery opening of the filling device and the entire bucket conveyor, a forming conveyor disposed outside the steam chamber and having a multiplicity of mold boxes movable along a predetermined path and pressing closures each movable with the mold box, the mold boxes and the pressing closures each having in a required portion a multiplicity of holes for selectively removing water contained in the coagulated soybean milk but preventing the passage of the coagulated soybean milk, and means for transferring coagulated soybean milk from the bucket conveyor to the forming conveyor.
Claim 2
Independent Claim 161 words
An apparatus for producing bean curd, by coagulating a mixture of soybean milk and bittern producing coagulated soy bean milk, comprising: an intermittently driven bucket conveyor having buckets stoppable one after another at a filling station; a filling device having a delivery opening directed downward to oppose each of the buckets from above when the bucket is at rest at the filling station, a steam chamber enclosing at least the delivery opening of the filling device and the entire bucket conveyor, a forming conveyor disposed outside the steam chamber and having a multiplicity of mold boxes movable along a predetermined path and pressing closures each movable with the mold box, the mold boxes and the pressing closures each having in a required portion a multiplicity of holes for selectively removing water contained in the coagulated soybean milk but preventing the passage of the coagulated soybean milk, and means for transferring coagulated soybean milk from the bucket conveyor to the forming conveyor.
Claim 3
Dependent Claim 17 words
An apparatus as defined in claim 1 wherein the holes are 0.6 to 0.9 mm in diameter.
Claim 4
Dependent Claim 34 words
An apparatus as defined in claim 1 wherein the path of travel of the buckets is provided with a breaker downstream from the filling station for breaking the soybean milk coagulated in the buckets.
Claim 5
Dependent Claim 24 words
An apparatus as defined in claim 1 further comprising a closed aseptic chamber in communication with the steam chamber and enclosing the forming conveyor.
