Thermal circulation rhizoma gastrodiae slice drying device

Abstract

The invention discloses a thermal circulation rhizoma gastrodiae slice drying device comprising a vertically arranged continuous S-shaped medicinal material drying channel. The medicinal material drying channel is externally provided with a continuous S-shaped shell matched with the medicinal material drying channel. The shell comprises an inner shell body and an outer shell body. A heat insulation layer is arranged between the inner shell body and the outer shell body. The inner wall of the inner shell body and the outer side of the medicinal material drying channel form a hot air channel. The surface of the medicinal material drying channel is provided with a plurality of holes communicating with the hot air channel at equal intervals. The top end of the medicinal material drying channel is provided with a feeding hopper through a valve. The lower end of the medicinal material drying channel is provided with a discharging hopper. The bottom end of the hot air channel is provided with an air inlet. The air inlet is connected with the output pipeline. The other end of the output pipeline is connected with a hot air blower through an electromagnetic valve. The top end of the hot air channel is provided with an air outlet. The air outlet is connected with the hot air blower through an input pipeline. According to the thermal circulation rhizoma gastrodiae slice drying device, through the S-shaped medicinal material drying channel, rhizoma gastrodiae slices can be conveyed and dried at the same time, the drying efficiency is high, the flowing direction of hot air in the hot air channel is opposite to the conveyance direction of the medicinal material, and therefore the rhizoma gastrodiae slices are dried more evenly; and after coming out from the air outlet, the hot air is circularly utilized through the input pipeline, so that energy is saved.

Description

technical field [0001] The invention relates to gastrodia elata processing equipment, in particular to a thermal cycle gastrodia elata slice drying equipment. Background technique [0002] The rhizome of Gastrodia elata is used as medicine to treat dizziness, numbness of limbs, and convulsions in children. It is a valuable traditional Chinese medicine. Long-term storage needs to be dried in slices. The traditional drying method is drying in the sun and drying in the shade. It has a long history in my country and is the most economical drying method. The cost is very low, but the corresponding efficiency is also low. The weather has a great influence, and there will be long-term mildew and damage. Contents of the invention [0003] In view of this, the object of the present invention is to provide a drying equipment for gastrodia elata slices with heat circulation, which can evenly and efficiently dry gastrodia elata slices, and can also recycle hot air to save energy.
