Mixed-flow mosquito-repellent incense drying device and mosquito-repellent incense drying system

Abstract

The invention provides a mixed-flow mosquito-repellent incense drying device and a mosquito-repellent incense drying system and relates to the technical field of mosquito-repellent incense drying. The mixed-flow mosquito-repellent incense drying device comprises a heat pump unit, a first air supply duct, a second air supply duct, a shared air return duct and a drying channel, wherein the heat pump unit drives air to flow, part of air passes through a first air supply opening to enter the drying channel, the other part of air passes through a second air supply opening to enter the drying channel, and the two parts of air meet in the drying channel and pass through the shared air return duct to enter a shared air return opening so as to realize circulation. Compared with a mosquito-repellent incense drying device in the prior art, the mixed-flow mosquito-repellent incense drying device has the advantages that the heat pump unit which feeds air into the two ends of the drying channel and collects air from the middle is adopted to realize bidirectional drying of a mosquito-repellent incense, the bidirectional air supply humitures can be independently controlled to meet the demand on humiture in the mosquito-repellent incense drying process, and accordingly, the mosquito-repellent incense drying quality and efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of mosquito-repellent incense drying, in particular to a mixed-flow mosquito-repellent incense drying device and a mosquito-repellent incense drying system. Background technique [0002] Mosquito-repellent incense is a mosquito-repelling and sterilizing medicinal product that prevents insect damage. It has been an essential thing for urban and rural consumers to repel mosquitoes in summer and autumn for a long time. However, the production technology and processing technology of mosquito-repellent incense require high requirements, especially the drying operation of mosquito-repellent incense. In the existing tunnel-type mosquito-repellent incense drying process, hot air is usually used to accelerate the evaporation of moisture in mosquito-repellent incense to achieve the purpose of drying mosquito-repellent incense. [0003] At present, the mosquito coils in the tunnel are dried by means of countercurrent h...

AI Technical Summary

Problems solved by technology

The inventors have found that with this method, when the mosquito coils first enter the drying room, the temperature of the hot air at the entrance of the tunnel drying room is relatively low, which is not conducive to the rapid drying of the mosquito coils; Easier to dry, while mosquito coils on the leeward side dry slower

In this way, the drying time of mosquito coils is prolonged and the drying efficiency of the tunnel drying room is reduced.
