Heat circulation device for central baking tobacco leaves

Abstract

The invention provides a thermal circulating device for central tobacco leaf baking, comprising fire coal stove, heat exchanger on upper side of said stove and baking room. The hot gas outlet in lower part of heat exchanger is connected with the hot gas channel on the bottom of baking room. It is characterized in that said hot gas channel is designed as the draught surface adapt to bottom shape of baking room, the upper part is equipped with air inlet connected to baking room, there are two air inlets on upper side of heat exchanger, one is located in channel where the heat exchanger is connected with baking room, the other is fixed on one side of heat exchanger, and the two inlets are covered with board. The device can realize forced ventilation and hot gas circulation, control temperature and humidity in baking room effectively and times, guarantee correct operation of tobacco baking, and increase baking quality. The invention is characterized by good mechanical property, high stability, reliable controllability and suitability for providing heat for large scale baking room.

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
