Circumferential multi-section distributed traditional Chinese medicine decoction piece drying and dehumidifying device

Abstract

The invention discloses a circumferential multi-section distributed traditional Chinese medicine decoction piece drying and dehumidifying device, and belongs to the technical field of traditional Chinese medicine decoction piece processing. The drying and dehumidifying device is characterized in that a plurality of groups of circumferentially distributed fan-shaped drying boxes are arranged, traditional Chinese medicine decoction pieces guided into the fan-shaped drying boxes are subjected to drying treatment under the intermittent circulation air guide effect, the traditional Chinese medicinedecoction pieces in the fan-shaped drying boxes can be easily scattered by hot air which is intermittently and circularly introduced, so that the traditional Chinese medicine decoction pieces can move up and down in the fan-shaped drying boxes in a dispersed manner, water in the traditional Chinese medicine decoction pieces can be effectively and quickly dissipated, dried hot air flows into a conical dehumidification cylinder to be dehumidified, dehumidified hot air is guided back to the outer sides of the fan-shaped drying boxes through a waste heat backflow mechanism and finally guided intothe air inlet end of an annular heating box, good waste heat utilization is achieved, on one hand, the heat preservation effect on the outer walls of the fan-shaped drying boxes is achieved, the drying efficiency is improved, and on the other hand, moisture is not prone to condensation on the inner walls of the fan-shaped drying boxes, and the drying time is not easily prolonged due to water drops.

Description

technical field [0001] The invention relates to the technical field of processing Chinese herbal decoction pieces, and more specifically relates to a circumferential multi-stage distributed drying and dehumidification device for decoction pieces of traditional Chinese medicine. Background technique [0002] Chinese herbal medicines are the medicines needed by Chinese medicine to treat patients. Compared with western medicines, although Chinese herbal medicines are slow to take effect and take a long time to treat, they have remarkable therapeutic effects and generally eradicate diseases, so they are widely used by people. When preserving Chinese herbal medicines, in order to prevent the Chinese herbal medicines from becoming moldy and deteriorating, it is necessary to dry the Chinese herbal medicines to remove the moisture on the premise of ensuring the medicinal properties. [0003] The traditional technology for drying Chinese herbal medicines mainly adopts the sun drying ...

Problems solved by technology

[0003] The traditional technology for drying Chinese herbal medicines mainly adopts the sun drying method, but because the sun drying method is greatly affected by the weather, especially for the rainy areas in southern China, it is more restricted

Therefore, the existing drying equipment is often used to dry the Chinese medicinal materials, but when the drying equipment in the prior art is drying the Chinese medicinal materials, there are many Chinese medicinal materials placed, and it is difficult to flatten them in the drying equipment. The internal heat spreads unevenly, so it is difficult for the medicinal materials to dissipate quickly, and it is easy to cause uneven heating of the Chinese medicinal materials, and the drying efficiency is low; in addition, the hot air is introduced into the drying equipment and exhausted from the drying equipment. The temperature of the shell of the drying equipment at the exhaust port is generally lower than the internal drying temperature. When the hot air is close to the shell with a lower temperature, it will condense into water on the surface, and the liquefied water droplets will be reintroduced into the drying machine. equipment, which undoubtedly prolongs the drying time
