Tobacco leaf baking equipment

Abstract

The invention aims to provide tobacco leaf baking equipment. The tobacco leaf baking equipment comprises a heating apparatus, a humidity discharging apparatus and a controller, wherein the heating apparatus comprises a biomass combustion furnace, a heat exchanger connected with an exhaust gas outlet pipe of the biomass combustion furnace, a circulating fan used for conveying hot air, and a feeding apparatus used for feeding to the biomass combustion furnace; the feeding apparatus comprises a hopper and a helical conveying part for conveying the material in the outlet of the hopper to the material inlet of the biomass combustion furnace; the humidity discharging apparatus comprises a humidity discharging opening and a humidity discharging window formed in the humidity discharging opening; and an oxygen supplying device, the circulating fan and the helical conveying part in the biomass combustion furnace are all connected with the controller. By adoption of the technical scheme, the tobacco leaf baking equipment has the advantages as follows: the overall tobacco leaf baking equipment is simple in structure; due to the integrated design of the heating apparatus, the humidity discharging apparatus and the controller, the tobacco leaf baking equipment is high in practicability; and the biomass combustion furnace is adopted for providing heat energy, so that the tobacco leaf baking equipment is green and environment friendly.

Description

technical field [0001] The invention relates to the technical field of tobacco leaf processing, in particular to a tobacco leaf curing equipment. Background technique [0002] Before the early 1970s, the tobacco leaf curing barn was a naturally ventilated air-flow ascending barn, with a modulation capacity of about 2 to 3 mu. The chimney is connected to the back of the combustion furnace. The high-temperature gas generated by fuel combustion passes through the ceramic fire pipe network laid at the bottom of the barn, and is discharged from the chimney. The air circulation system only has underground holes and skylights. Cold air enters from the underground holes, and heated air flows from the bottom. It flows naturally above the heated combustion furnace and the surface of the fire tube, and continues to rise with heat to heat the tobacco leaves and stabilize the temperature in the barn. Open the skylight, and the hot air will naturally flow out from the skylight to achieve ...

Problems solved by technology

[0004] In the early 1990s, Guizhou Tobacco Research Institute developed the downflow barn, which has the following characteristics: first, there is no fire pipe on the ground of the smoke chamber, which makes it more convenient and safe to install and unload smoke; second, The temperature and humidity in the smoking room are less affected by environmental conditions, and some hot air circulates; third, the temperature difference between the upper and lower floors of the barn is large, and the dehumidification effect is not good

Intensive curing barns have the advantages of easy color determination, shortened brewing cycle, and high consistency of tobacco leaf appeara...
