Tobacco curing vaporization furnace

Abstract

A tobacco curing vaporization furnace comprises a furnace body, a furnace lid, a fuel hopper and an air blowing system, wherein the furnace lid is arranged on the furnace body in a covering mode, the fuel hopper is arranged on the furnace lid, and a steam chamber for generating steam used for tobacco leaf conditioning is formed in the furnace lid. The furnace body comprises an outer wall and a furnace chamber formed inside the outer wall, a water tank is arranged between the outer wall on the upper portion of the furnace body and the furnace chamber, an iron ring is arranged at the bottom of the furnace chamber, a soil ring is placed in the iron ring, and a fire outlet pipe leading to the outside is arranged on the upper portion of the furnace chamber; the furnace lid comprises a combustion chamber and the steam chamber, the vertical wall of the combustion chamber is matched with the water tank, a water inlet pipe and a steam exhaust pipe are arranged at the top of the steam chamber, and a valve is arranged on the water inlet pipe. The tobacco curing vaporization furnace has the functions of combusting straw and coal powder and providing steam for tobacco leaf conditioning; the fuel hopper throws fuel into the furnace chamber from the upside of the furnace lid to ensure sufficient combustion of the fuel; as the steam chamber is formed in the furnace lid, the steam generation efficiency is guaranteed without occupying extra space.

Description

technical field [0001] The invention relates to a flue-cured tobacco furnace, in particular to a flue-cured tobacco gasification furnace. Background technique [0002] The current tobacco leaf baking furnaces generally adopt coal-fired heating, and there are problems of insufficient coal combustion, low efficiency, and high coal-burning costs during use. Straw gasification furnaces and burning coal after pulverization can ensure full utilization of fuel, but there is currently no gasification combustion furnace designed for tobacco leaf baking. [0003] Moreover, after the tobacco leaves are cured, they must go through a moisture regain treatment process so that the moisture content reaches about 18% that meets the requirements. In the traditional technology, the method of moisture regaining of tobacco leaves is generally to open the skylight and furnace door of the flue-curing room after the flue-cured tobacco is finished. Both methods have the disadvantages of long moist...

Problems solved by technology

In the traditional technology, the method of moisture regaining of tobacco leaves is generally to open the skylight and furnace door of the flue-curing room after the flue-cured tobacco is finished. Both methods have the disadvantages of long moisture regain time and difficult control of moisture regain

Chinese patent application 201120429046.7 discloses a "flue-cured tobacco resurfacing device", which includes an atmospheric boiler, a high-pressure water pump and an atomizing nozzle. The high-pressure water pump is connected to the atomizing nozzle through a water pipe, and a steam delivery pipe is drawn from the atmospheric pressure boiler. In this way, the steam delivery pipe and the atomizing nozzle can be connected to the barn at the same time, thereby shortening the time for the flue-cured tobacco to regain moisture, and it is convenient to use. However, the steam in this device depends on the boiling water in the boiler, and the boiler only has a steam supply. role, resulting in waste of equipment

[0004] Chinese Patent Application No. 201310098825.7 discloses a heating furnace for flue-cured tobacco room, which realizes two functions of heat supply and steam supply. and the water inlet are designed outside the furnace body, occupying space

The heating tube is installed at the bottom of the fire chamber, which is easy to be damaged during use, and the temperature at the bottom of the fire chamber is low, and the heating effect is poor
