Preparation method of granular essence and granulation device thereof

The invention provides a preparation method of granular essence and a granulation device thereof. The preparation method specifically comprises the following operation steps: S1, pretreatment of raw materials, S2, extraction of the raw materials, S3, treatment of the raw materials, S4, preparation of ingredients, S5, mixing of the materials, and S6, granulation. According to the invention, after being mixed, the materials are rotated through the driving shaft, the spiral blades are driven to rotate to feed materials into the feeding groove, the materials in the feeding groove are extruded to the lower side of the mixing box body through the forming holes and form a cylindrical shape, at the moment, the mixing box body drives the cylindrical materials to rotate, the materials are cut into particle shapes by the cutting blades, and the particles fall onto the surface of the spiral discharging plate, so that granulation is completed; and in the granulating process, the use of carrier powder and essence spraying
