Heat-exchange dehumidification method of tobacco baking device

Abstract

The invention relates to a heat-exchange dehumidification method of a tobacco baking device, and relates to the technical field of tobacco baking. According to electric power consumed in the running process of a sealed dehumidification heat pump, due to a power conservation principle, one part of energy is finally converted into heat so as to be carried into a drying room along air circulation, so that the temperature of a drying room is improved; and in addition, according to a tobacco drying process, constant temperature and constant humidity need to be kept in a specific time period, a surface air cooler is additionally arranged in a drying system, and heat is taken away through circulating water in the surface air cooler and a cooling tower, so that on one hand, the temperature in the drying room is ensured to be adjustable and a baking process of tobacco leaves is met, and on the other hand, most sensible heat of return air is taken away, the cooling capacity of a dehumidification system is indirectly increased, and finally the dehumidification efficiency of the dehumidification heat pump is improved.

Description

technical field [0001] The invention relates to the technical field of tobacco curing, in particular to a cooling tower cooling system for tobacco curing heat pump equipment and a heat exchange and dehumidification method for a tobacco curing device. Background technique [0002] As the main raw material of cigarettes or other similar products, tobacco itself is a plant, so before making cigarettes, multiple processes are required to make it reach a predetermined state. Among them, drying, as one of the many processes, directly determines the quality of tobacco. quality. [0003] The process of tobacco drying needs to maintain a constant temperature and constant humidity for a specific period of time. Too high temperature and too low humidity will cause excessive drying of tobacco, resulting in the problem of brittleness and sticky taste of tobacco. Similarly, too low temperature and humidity If it is too high, the moisture in the tobacco will exceed the standard, and probl...

AI Technical Summary

Problems solved by technology

[0003] The tobacco drying process needs to maintain a constant temperature and constant humidity state for a specific period of time. If the temperature is too high and the humidity is too low, the tobacco will be dried too much, causing the tobacco to become brittle and burnt. Similarly, if the temperature is too low and the humidity If it is too high, the moisture in the tobacco will exceed the standard, and problems such as mold will easily appear in the later storage. The above two situations will affect the taste of the product after it is made into finished cigarettes
