Embodiment Construction

[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0020] look first figure 1 , figure 1 A schematic structural view showing an embodiment of the present invention: As can be seen from the figure, the curing room of the present invention is composed of the first-level curing room 3, the second-level curing room 8 and the third-level curing room 13 in series in sequence, and the tobacco curing The order of roasting is also carried out from the first-level oven 3 to the third-level oven 13; an overhead layer is provided at the lower part of the third-level oven, and the overhead layer is composed of a waste heat air layer 15 and a new air layer 17 stacked from bottom to top. And waste heat air layer two 19 forms.

[0021] The new air layer 17 runs through the three-stage barn, and the front end of the new air layer 17 communicates with the heat pump unit room (i.e. figure 1 The frontmost spac...

Abstract

The invention discloses a tobacco curing method with heat used in a grading-circulating mode and a system structure. A curing chamber structure is formed by three grades of curing chambers for curing tobacco in different stages in a series-connecting mode. At least one set of curing frame is arranged in each grade of curing chamber. The curing frames operate between the three grades of curing chambers through communication tracks. Through an air circulating channel formed by an empty-space layer arranged on the lower portion of each grade of curing chamber and a drying system and an air extracting device in each grade of curing chamber together, heat of air is used between the three grades of curing chambers in a grading-circulating mode. Air energy is used as a heat source, a body structure is designed to be a three-grade-curing-chamber system based on the characteristics of a tobacco curing technology process, bottom empty space layer design is achieved, the tracks are communicated with water flow work, the effect of heat step-by-step circulating using is achieved, waste heat using rate is greatly improved, and the energy loophole of the current rural area tobacco curing technology is filled.

Description

technical field [0001] The invention relates to a tobacco curing production system, in particular to a tobacco curing method and a system structure for rural tobacco curing using graded and recycled heat. Background technique [0002] Tobacco is a common consumer product in modern society. The output of flue-cured tobacco in China accounts for more than 80% of the total tobacco products. The production of flue-cured tobacco is mainly concentrated in Yunnan, Henan, Guizhou, Shandong and other provinces. The production process of flue-cured tobacco can be roughly divided into three stages: seedling raising, field growth and tobacco leaf curing. Tobacco curing is one of the key links to reflect and determine the quality and production benefits of flue-cured tobacco. It involves the organic cooperation of many factors such as the quality of tobacco leaf harvesting, curing room equipment, curing process and practical experience. Therefore, the curing of tobacco leaves is a syst...
