PURPOSE:To prepare pure powdery soy capable of giving soy having the same quality as the raw soy when reconstituted with hot water, etc., economically, without adding additives, by concentrating the raw soy with a centrifugal thin- layer vacuum concentration apparatus at a low temperature, and drying with a vacuum dryer at a low temperature. CONSTITUTION:The raw soy is supplied from the stock liquid tank 1 to the conical rotor 6 of the vacuum vessel 5 attached to the centrifugal thin-layer vacuum concentration apparatus A. The soy is spread and transferred in the form of a thin layer on the evaporation surface 6' of the rotor 6 by the rotation of the rotor 6, and is heated at a low temperature under reduced pressure to effect the instantaneous concentration. The concentrated soy is discharged from the concentrate discharge tube 12, supplied to the vacuum dryer B, and dried at a low temperature. The obtained powdery soy is delivered from the product outlet port 40. |
