Amylase enzymolysis device and method

The invention relates to the technical field of preparation of spiral dextrin through amylase enzymolysis, in particular to an amylase enzymolysis device and method. The device comprises a device body, the device body comprises a stirring tank, and a first cavity and a second cavity which are communicated are formed in the stirring tank; the first chamber has a first form and a second form; the inner diameter of the first chamber in the first form is wider than that of the second chamber, and the first chamber in the first form is used for stirring and gelatinizing starch; the volume of the first cavity in the second form is smaller than that of the first cavity in the first form, and the first cavity in the second form is used for being matched with the second cavity for starch enzymolysis. When the device is used, the first cavity in the first form is independently used as a stirring cavity for starch gelatinization. The inner diameter of the first chamber is wide, so that deposition in the starch stirring
