Drying device for stevia powder

Abstract

The invention discloses a stevioside fruit powder drying device which comprises a drying mechanism and a smashing mechanism. The drying mechanism and the smashing mechanism communicate with each other through a corresponding pipeline. The drying mechanism comprises a drying box, a drying plate, a conveyor packing auger, a stirring shaft, stirring rods, a refrigerant pipe and a heating pipe, wherein the refrigerant pipe and the heating pipe are arranged in the drying box. The drying box is a closed cylindrical box capable of achieving vacuumization. A feed inlet is formed in one side of the upper end of the drying box. The drying plate is spirally arranged in the drying box and connected with the inner wall of the drying box. The stirring shaft is vertically arranged in the center position of the drying box. The multiple stirring rods are movably arranged in multiple axial positions of the stirring shaft in the mode of moving in the radial direction. The stirring rods can stir materials remaining on the drying plate, and the drying efficiency is improved.

Description

technical field [0001] The invention relates to plant crushing and drying equipment, in particular to a drying device for stevia candy powder. Background technique [0002] In order to change the bitter taste of stevia, the applicant in this case designed a fruit-flavored compound sweetener, which used fruit powder, such as blueberry fruit powder, so the production of sweeteners involves the drying and milling of fruit plants. [0003] In the patent of invention with the patent number ZLCN201310678847.0, the applicant of this case discloses a processing device that integrates independent drying and milling equipment. Nutrients and unique flavors can be continuously produced in a flow-type manner during the milling process without generating dust and affecting the production environment; however, the above-mentioned processing device has the following problems: when the friction between the material and the drying plate is large, the material is easy to It stays on the dryin...

[0003] In the patent of invention with the patent number ZLCN201310678847.0, the applicant of this case discloses a processing device that integrates independent drying and milling equipment. Nutrients and unique flavors can be continuously produced in a flow-type manner during the milling process without generating dust and affecting the production environment; however, the above-mentioned processing device has the following problems: when the friction between the material and the drying plate is large, the material is easy to It stays on the drying plate all the time, resulting in low drying efficiency; the discharge valve is composed of a relatively rotating valve seat and valve core. When the valve is opened, there is still a nearly half area of ​​the blocking surface, and the discharge efficiency is low; the crushing mechanism only exists A set of grinding discs, the crushing effect is not ideal
