Valve mechanism for stevia confectionery powder processing

Abstract

The invention discloses a valve mechanism for processing stevioside fruit powder. The valve mechanism is mounted at a discharging opening in the bottom of a drying box and comprises a shell, an upper seat plate, a lower seat plate, a threaded rod, two valves, sliding grooves and a nut. The shell is connected to the bottom of the drying box. The upper seat plate is arranged at the upper end of an inner chamber of the shell, and the lower seat plate is arranged at the lower end of the inner chamber of the shell. The threaded rod is vertically arranged in the center of the inner chamber of the shell. The upper end of the threaded rod is connected to the upper seat plate in a rotary manner, and the lower end of the threaded rod is connected to the lower seat plate in a rotary manner. The two valves are arranged at the two sides of the threaded rod correspondingly and symmetrically hinged to the bottom of the upper seat plate. The two sides, in the radial direction, of the nut are each provided with a protruding block, and the two sides in the radial direction perpendicular to the radial direction are each provided with a push plate extending in the direction of the corresponding valve. The two sliding grooves are formed in the two sides of the threaded rod correspondingly and correspond to the positions of the protruding blocks on the nut. The nut is connected to the threaded rod in a rotary manner, and each protruding block is connected into the corresponding sliding groove in a sliding manner. The valve mechanism is large in discharging area.

Description

technical field [0001] The invention relates to plant crushing and processing equipment, in particular to a valve mechanism for processing 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 s...

[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
