Tobacco drying device

Abstract

The invention discloses a tobacco drying device. The tobacco drying device comprises a tobacco drying chamber, a humidity control module, a temperature control module, a cooling capacity storage water tank, a heat storage water tank and a water source hot water heat pump. The humidity control module is used for independently controlling the air humidity of the tobacco drying chamber. The temperature control module is used for independently controlling the air temperature of the tobacco drying chamber. The cooling capacity storage water tank is used for supplying a refrigerant for cooling air to the humidity control module. The heat storage water tank is used for recycling heat in the tobacco drying chamber after tobacco is dried. The water source hot water heat pump achieves heat transmission of water in the cooling capacity storage water tank and the heat storage water tank in a heat pump work manner. According to the tobacco drying device, the temperature and humidity in the drying process can be independently controlled, tobacco drying can be conducted completely according to a traditional temperature and humidity control curve, and the taste of tobacco is kept consistent with traditional taste. Meanwhile, the drying process is conducted under the closing condition, the smell of the tobacco is stored well, energy can be cyclically utilized in the drying process, energy saving and environment friendliness are achieved, and cost is low.

Description

Technical field [0001] The invention relates to a tobacco drying device, in particular, to a tobacco drying device with independent temperature and humidity control. Background technique [0002] Tobacco drying is an indispensable processing step in tobacco production. Coal-fired curing tobacco to dry the tobacco is a long-term and widely used curing method for tobacco curing in my country. Tobacco curing requires a lot of energy. Ordinary curing rooms use coal for direct heating, which has low heat utilization rate and high coal consumption. Usually, it takes 1.5-2.5kg standard coal to dry 1kg of tobacco. SO produced by coal combustion 2 , NO x Such harmful substances also seriously pollute the atmosphere and affect people's health. [0003] As China's environmental protection laws and regulations become more stringent, it has become an inevitable trend to find clean tobacco drying technology. At the same time, because the tobacco drying method affects the appearance and taste of...

Problems solved by technology

[0004] (1) Use air energy as the heat source to provide heat source for tobacco drying, and adopt the exhaust method to control humidity; the advantage of this technology is that temperature and humidity can be independently controlled during the tobacco drying process, but the disadvantages are: (1) The influence of environmental temperature and humidity Drying quality, (2) During the exhaust process, the tobacco aroma is discharged to the atmosphere together, (3) After the tobacco is dried, the heat of the tobacco is cooled by natural cooling, which consumes a lot of heat energy

Its disadvantages are: (1) It is difficult to achieve independent control of temperature and humidity during the tobacco drying process, that is, the humidity is always in a state of change during the drying process, and the taste and appearance of dried tobacco are different from those of tobacco dried in a traditional way; (2 ) After the tobacco is dried, the heat of the tobacco is cooled by natural cooling, which consumes a lot of heat energy
