Automatic sand removing dryer without damage to rhizoma coptidis

Abstract

The invention discloses an automatic sand removing dryer without damage to rhizoma coptidis. The automatic sand removing dryer comprises a rack and a reducer motor, wherein the mounting surface of the rack is an inclined surface; the reducer motor is arranged on the mounting surface of the rack; the inclination angle of the rack is 15-45 degrees; a main shaft of the reducer motor is in transmission connection with a feed end of a pipe cage which is formed by bundling a plurality of steel pipes; an electric heating pipe connected with a power supply is arranged in each steel pipe of the pipe cage; an obliquely arranged sand receiving disk is arranged below the pipe cage; the tail end of the sand receiving disk is connected with a sand receiving hopper; the pipe cage is in sliding fit with the rack; a plurality of baffle plates evenly distributed along the axial direction of the pipe cage are arranged on the inner wall of the pipe cage; the baffle plates are semicircular thin plates; the phase difference between the adjacent baffle plates on the inner wall of the pipe cage is 90 degrees; a feed port is formed in the feed end of the pipe cage; a discharge port is formed in a discharge end of the pipe cage; and the discharge port of the pipe cage is connected with a screw conveyer. The automatic sand removing dryer has the advantages of simple structure, high efficiency, good aeration-drying effect, and no damage to rhizoma coptidis, and has the advantage of separating dirt from rhizoma coptidis during drying.

Description

technical field [0001] The invention relates to the field of processing machinery, in particular to an automatic desand drying machine which does not damage Coptis chinensis. Background technique [0002] Coptis chinensis, also known as Chuanlian, Weilian, and Jizhulian, is a perennial herbaceous plant belonging to the family Ranunculaceae and Coptis genus. It has leaf bases, firm paper, ovate triangles, three entire lobes, and the central lobe is ovate and diamond-shaped, pinnately deeply lobed, Edges are sharply serrated, lateral lobes ranging from 2-parted; petiole 5-12cm long. Wild or cultivated in cool and humid shaded forests in valleys at an altitude of 1000-1900m. It has the effects of clearing away heat and dampness, purging fire and detoxifying. Undried rhizomes of Coptidis rhizomes are commonly known as "Coptis chinensis Mao Tuo". The rhizomes have a large number of root hairs, and a large amount of soil is attached to the root hairs, which are extremely difficu...

AI Technical Summary

Problems solved by technology

The water content of the freshly excavated Coptis chinensis and the soil it contains is about 90%, if it is not dried in time, it is prone to mildew, which will affect the quality of Coptis chinensis

In the prior art, Coptis chinensis is dried in a closed space, and the ventilation effect in the drying room is poor, which is not conducive to the discharge of water vapor and affects the drying effect, and the soil attached to Coptis chinensis remains in the drying room, and it is dried There is a certain damage to Coptidis itself
