Heat circulation device for central baking tobacco leaves

Abstract

The invention provides a heat cycle device for intensively curing tobacco leaves, which includes a coal-fired stove, a heat exchanger located above the coal-fired stove, and a baking chamber, wherein the hot gas outlet at the lower part of the heat exchanger and the hot gas channel at the bottom of the baking chamber It is characterized in that the hot air channel is set as a ventilating surface adapted to the shape of the bottom surface of the baking chamber, and an air inlet connected to the baking chamber is arranged at intervals above it, and the air inlet on the upper part of the heat exchanger is provided with Two, one of which is arranged in the channel connecting the heat exchanger and the baking chamber, and the other is arranged on one side of the heat exchanger, and two air inlets are provided with cover plates. It can conveniently realize forced ventilation and hot air circulation, timely and effectively control the temperature and humidity in the curing room, ensure the accurate execution of the high-quality tobacco curing process, improve the overall curing quality of tobacco leaves, and make the tobacco leaves baked better than ordinary curing rooms. The color of the tobacco leaves is uniform, the saturation is good, the color difference between the front and back of the tobacco leaves is small, the quality level of the whole house tobacco is uniform, and the overall quality is improved. The invention has good mechanical properties, high stability, strong operation and controllability, and saves labor and time. The invention is very suitable for providing thermal cycle heating for large-capacity baking chambers.

Description

technical field [0001] The invention relates to a thermal cycle device, in particular to a thermal cycle device for intensively roasting freshly picked tobacco leaves. Background technique [0002] At present, the baking of tobacco leaves is still at a low level of family-style baking, and most of the baking equipment are backward soil curing houses that almost every family has. Due to many defects in the structural design and configuration of the soil curing houses, the actual In use, only the experience of the operator can be used to adjust the temperature and humidity during the baking process. Not only is it labor-intensive and occupies extremely limited land resources, but also frequent opening and closing of the baking room door will easily lead to increased heat loss and temperature fluctuations. At the same time, the waste heat air after curing tobacco leaves can no longer be used, thereby increasing the consumption of coal resources. What is more serious is that it ...

[0002] At present, the baking of tobacco leaves is still at a low level of family-style baking, and most of the baking equipment are backward soil curing houses that almost every family has. Due to many defects in the structural design and configuration of the soil curing houses, the actual In use, only the experience of the operator can be used to adjust the temperature and humidity during the baking process. Not only is it labor-intensive and occupies extremely limited land resources, but also frequent opening and closing of the baking room door will easily lead to increased heat loss and temperature fluctuations. At the same time, the waste heat air after curing tobacco leaves can no longer be used, thereby increasing the consumption of coal resources. What is more serious is that it is difficult to control the temperature and humidity in the curing room in a timely manner, which affects the curing quality of tobacco leaves and reduces the quality of tobacco leaves. The hard work of tobacco farmers for a year will not be compensated economically, and it will also affect the production of high-quality products of tobacco companies
