Industrial preparation method of wheat protein hydrolysate

The invention discloses a method for preparing a wheat protein hydrolysate product. The method takes wet gluten as raw material, comprises the main steps of grinding the gluten, mixing the raw material and enzyme, carrying out an enzymolysis reaction, sterilizing at high temperature, carrying out spray drying and the like, and is realized sequentially by a table type meat mincer, a feeding tank, an enzymolysis tank, a heat insulation tank and a spray drying tower; the wheat protein hydrolysate product is good in water solubility; the method belongs to the field of comprehensive development and application of wheat deep processing. The method solves the problem that the protein hydrolysate is stably and continuously produced by taking the wet gluten as raw material; the product is the extension of the industrial chain on the basis of wheat protein (wheat gluten); the water needed by the reaction is reduced, and the drying cost is lowered; after the method is adopted, the protein hydrolysate which is smaller in
