Technical Field

[0001] This utility model relates to the technical field of starch processing, and in particular to a hot air convection drying device for starch milk. Background Technology

[0002] Even after gelatinization and dehydration, starch still contains a large amount of moisture and requires drying before storage. Existing technology announcement CN207963334U discloses a starch drying rack for sweet potato starch production, including a base plate, an illumination lamp, support rods, a drying rack, a fixing mesh, air outlets, an air inlet pipe, a reflector plate, and a reflective groove. The base plate has support rods and an illumination lamp, the support rods have a drying rack and a reflector plate, the drying rack has an air inlet pipe, air outlets, and a fixing mesh, and the reflector plate has a reflective groove. However, starch is prone to clumping and difficult to disperse, making it difficult to dry the inside of the starch clumps, thus affecting product quality. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a starch emulsion hot air convection drying device that can agitate starch, ensure drying efficiency, break up clumps of starch, and allow it to be fully dried.

The lifting component is installed on the outer wall of the drying cylinder, the holding component is installed on the lifting component, and the stirring component is installed on the holding component. The drying component is installed inside the drying cylinder. Starch milk is placed into the holding component, and the lifting component moves the holding component up and down, facilitating the addition and removal of starch from the drying cylinder, thus improving work efficiency. The stirring component agitates the starch, ensuring drying efficiency and breaking up clumps of starch, allowing it to be fully dried and improving practicality.

[0005] Preferably, the holding component includes a top plate, two vertical plates, a sealing ring, and multiple holding plates. The top plate is located above the drying cylinder, with vertical plates installed at the left and right ends of the bottom of the top plate. A sealing ring is installed at the bottom of the top plate, and the sealing ring is sealed to the top of the drying cylinder. Multiple holding plates are evenly installed between the two vertical plates, and a discharge port is provided on one side of the bottom of each holding plate.
