Energy recycling type edible mushroom drying device

Abstract

The invention discloses an energy recycling type edible mushroom drying device. The drying device comprises an external fresh air introducing device, a total heat exchanger, a multistage pressing type airflow-adjustable air hole, an edible mushroom drying device and an induced draft fan, wherein the total heat exchanger is used for recycling the energy; the edible mushroom drying device sequentially comprises a drying room, an air pre-heater, a flow guiding plate, a variable cross-section air flue, an airflow pressure sensor, a blowing pore plate, an air return pore plate, and flow guiding devices arranged on an inlet of the blowing pore plate and an outlet of the air return pore plate, and the blowing pore plate and the air return pore plate are arranged in the drying room in parallel. According to the energy recycling type edible mushroom drying device, by combining a completely-new air supplying drying mode and a direct return-air self-circulation drying mode with a stairstep-energy-supplying air heating manner and the variable cross-section air flue according to different drying conditions of the edible mushroom, the stable distribution of air in the device is guaranteed, meanwhile, the air supplying temperature is decreased, and the drying quality is guaranteed; air is uniformly processed, and the energy consumption is reduced.

Description

technical field [0001] The invention belongs to the technical field of building environment and equipment engineering, and relates to an energy recovery air treatment system, in particular to an energy recovery type edible fungus drying system. Background technique [0002] The baking room is widely used in the drying of various mechanical equipment and food. The current popular drying technologies are mainly ultraviolet drying, infrared drying, electromagnetic drying and hot air drying. The heating methods mainly include electric heating, steam heating, gas heating, heavy oil heating, etc. These technologies are not only costly, but also sometimes cause environmental pollution. There are also many traditional baking rooms with simple equipment, low initial investment, low baking efficiency, and poor quality of dried food. [0003] The introduction of heat pump technology and the utilization of clean new energy such as solar energy have greatly promoted the development of...

AI Technical Summary

Problems solved by technology

However, the air supply static pressure space and the return air static pressure space are small, and the parallel air supply method in the baking workshop cannot fully achieve the effect of uniform and stable air flow organization, and the drying effect of edible fungi is not good; Wind is used for internal recirculation of the drying device, which does not recover energy to a large extent, nor does it ensure its dryness and cleanliness

Furthermore, conventional air outlets usually have a constant air volume, and the same air volume is used for different quantities of edible fungi, which not only causes waste, but also affects the drying effect of edible fungi
