Medicinal material dryer

Abstract

The invention provides a medicinal material dryer. The medicinal material dryer comprises a box body, a closed-loop rail, a plurality of sets of transportation wheels and net-shaped rotating barrels, wherein hot air is circulated in the box body; the closed-loop rail is covered with the box body; the multiple sets of the transportation wheels pulled with one another are located at the rail; one net-shaped rotating barrel containing medicinal materials is sleeved with each set of the transportation wheels; one ends of the rotating barrels are opened, and the other ends of the rotating barrels are sealed; a motor drives the transportation wheels located at the end of transportation wheel sets to roll on the rail and drives the other transportation wheels to walk; the outline of the box body is matched with the shape of the rail, and the box body is provided with a broken opening used for taking out and placing the rotating barrels. Compared with a traditional dryer, the medicinal materials can be overturned in the transportation process, the heating area of the medicinal materials is increased, and drying is more uniform; the heating time of the medicinal materials can be prolonged by repeated heating through the closed-loop transportation rail on the condition that a transportation line is not lengthened, so that the structure of the dryer is more compact, heat is used more fully, and heat loss is reduced.

Description

technical field [0001] The invention belongs to the technical field of pharmaceutical equipment, in particular to a medicinal material drying machine. Background technique [0002] In the field of traditional Chinese medicine pharmaceuticals, it usually involves drying the raw materials of medicinal materials, that is, heating and drying the raw materials of medicinal materials to a certain water content, and then performing subsequent processing. The above drying process is completed by a dryer. Existing dryers are generally conveyor belt dryers, and the medicinal materials are gradually dried under the action of hot air during the process of conveying along the conveyor belt. The drying speed of the medicinal materials is slow and the drying effect is uneven due to the lack of turning action on the medicinal materials. In order to ensure the degree of drying, it is necessary to prolong the drying time and the length of the conveyor belt, which not only increases energy con...

AI Technical Summary

Problems solved by technology

The drying speed of the medicinal materials is slow and the drying effect is uneven due to the lack of turning action on the medicinal materials. In order to ensure the degree of drying, it is necessary to prolong the drying time and the length of the conveyor belt, which not only increases energy consumption but also makes the dryer equipment too large

[0003] Therefore, there are some compact medicinal material dryers in the prior art, which are heated during the turning of medicinal materials. Although the structure is compact, the drying efficiency is low due to the compact structure and small volume, and the heat loss is serious.
