Continuous heat pump drying room and using method thereof

Abstract

The invention relates to the technical field of traditional Chinese medicine machinery, in particular to a continuous heat pump drying room and a using method thereof. The continuous heat pump drying room comprises a plurality of heat drying room units which are connected end to end; heat insulation devices are arranged among the heat drying room units; and each heat drying room unit further comprises a heat pump. In the using process, the hot drying room units are started one by one, so that materials pass through the hot drying room units one by one to be heated and dried; compared with a single sealed drying room in the prior art, feeding and discharging operation does not need to be carried out after the drying room is cooled; energy consumption is reduced; meanwhile, the drying efficiency is improved; compared with a conveyor belt type dryer, on one hand, the sealing performance of the whole mechanism is guaranteed; heat loss is reduced; on the other hand, the whole mechanism does not need to be heated; part of the hot drying room units can be kept in a non-working state when feeding is just carried out and feeding is finished; energy consumption is reduced; and the advantages of being high in drying efficiency and low in energy consumption are achieved.

Description

technical field [0001] The invention relates to the technical field of traditional Chinese medicine machinery, in particular to a continuous heat pump drying room and a use method thereof. Background technique [0002] Drying is an important step in the processing of traditional Chinese medicines. At present, in this technical field, drying rooms are mainly used instead of natural air drying as the main means of drying traditional Chinese medicines. [0003] At present, there are mainly two types of traditional Chinese medicine dryers, one is a single sealed drying room, such as a high-efficiency and energy-saving small traditional Chinese medicine dryer with application number CN201920255786. The interior of the body is divided into the first drying cavity, the first pipeline and the second drying cavity from left to right by vertical partitions, and the inner walls of the first drying cavity and the second drying cavity are from top to bottom. There are multiple sets of b...

Problems solved by technology

The problem with this kind of dryer is that it takes a long time to heat up. When in use, the dryer needs to be heated as a whole, and then the medicinal materials are placed on the conveyor belt to make it slowly move with the conveyor belt. It takes more than ten hours to leave the dryer, so when the dryer is in use for the first ten hours and the last ten hours of operation, the conveyor belt is not filled with materials, which greatly increases the cost of drying. and not conducive to reducing energy consumption
