Dehumidifying heat pump unit and tobacco-dehumidifying heat pump baking device

Abstract

The invention discloses a dehumidifying heat pump unit and a tobacco-dehumidifying heat pump baking device. The tobacco-dehumidifying heat pump baking device comprises a closed baking box provided with a tobacco baking region and a functional region. A partition is disposed between the tobacco baking region and the functional region. The tobacco baking region is communicated with the functional region through an air supply port and an air return port on the partition. A tobacco support is disposed in the tobacco baking region. The dehumidifying heat pump unit is disposed in the functional region. The tobacco-dehumidifying heat pump baking device has the advantages that tobacco can be dried in a fully closed state, no pollution is emitted, the device is insusceptible to weather and highly energy-saving and consumes energy 0.8kw / h per kilogram of dry tobacco, and standard drying cost of each bake of the tobacco is about 300Yuan, and the baked tobacco is high in quality.

Description

【Technical field】 [0001] The invention relates to the field of roasting equipment, in particular to a dehumidification heat pump assembly and a tobacco dehumidification heat pump roasting device. 【Background technique】 [0002] The current commonly used process for tobacco drying is the flue-cured tobacco three-stage curing process, and realizes the automatic control of temperature and humidity in the intensive curing room and ordinary curing room, but the baking generally uses coal-fired intensive curing room. However, the coal-fired intensive barn is an open drying mode, which is greatly affected by the weather. When the weather is humid, the drying cycle is long, and the quality of the tobacco leaves is reduced; when the ambient temperature is low, the energy consumption is high; the moisture removal takes away a lot of heat; Part of the energy; the energy is operated by manual coal addition, the temperature and humidity control is difficult, and the drying quality is gre...

AI Technical Summary

Problems solved by technology

[0004] However, the high-temperature heat pump tobacco curing room has deficiencies that need to be improved: the open drying mode is greatly affected by the weather, the drying cycle is long when the weather is humid, the quality of the tobacco leaves is reduced, and the energy consumption is high when the ambient temperature is low; the humidity is removed at the same time A lot of heat, large heat loss; limited by the ambient temperature, it is difficult to apply when the temperature is low in the later stage of tobacco leaf picking
