Method for far-infrared heating and baking of tobacco leaves

Abstract

The invention discloses a method for far-infrared heating and baking of tobacco leaves, as for the method, a plurality of groups of far-infrared carbon fiber electric heating pipes are mounted in a tobacco leaf loading room of a baking room, a far-infrared electric heating system is further constituted, and a temperature and humidity automatic controller and a power supply controller are used for control; in the heating system, the far-infrared carbon fiber electric heating pipes are fixed in a housing of the far-infrared carbon fiber electric heating pipes and uniformly mounted at a basement on the periphery of the ground of the tobacco leaf loading room of the baking room; a circulating fan is mounted in a heating room as a hot air circulating channel; the far-infrared carbon fiber electric heating pipes are matched and mounted on the inner wall of a wall; and all the far-infrared carbon fiber electric heating pipes are connected by conducting wires in groups, and a heating control system is formed through the temperature and humidity automatic controller and the power supply controller. The method has the advantages of high temperature control precision, simpleness in operation, low heat loss, no emission of harmful gas and the like; by adopting the method, the utilization rate of heat can be effectively improved, the labor intensity for baking can be reduced, the amount of labor used is small, and the contemporary requirements on energy conservation, environmental protection and reduction of carbon emission can be met.

Description

technical field [0001] The invention relates to a device and a process method for drying tobacco, in particular to a heating method for a dense barn. Background technique [0002] The traditional flue-cured tobacco intensive curing room mainly includes a tobacco loading room and a heating room. The heating room is composed of a metal stove, a heat exchanger and a circulation fan. The heating energy is mainly coal, and the heat of coal combustion is transferred through the heat exchanger. Under the action of the hot air circulation channel, the heat is transferred to the smoke chamber. This heating method must manually control the addition of coal at any time, the operation frequency of the baking process is high, and the temperature and humidity are not easy to control. The coal used in the traditional intensive barn is mostly bituminous coal. The combustion of bituminous coal will produce a large amount of harmful gases such as sulfur dioxide and carbon monoxide. On the on...

Problems solved by technology

This heating method must manually control the addition of coal at any time, the operation frequency of the baking process is high, and the temperature and humidity are not easy to control

The coal used in the baking of traditional intensive barns is mostly bituminous coal. The combustion of bituminous coal will produce a large amount of harmful gases such as sulfur dioxide and carbon monoxide. On the one hand, these harmful gases are easy to corrode metal stoves, heat exchangers and chimneys, reducing the service life of equipment , these harmful gases are discharged into the atmosphere through the chimney, which will also cause great pollution to the environment

Although people continue to transform the tobacco leaf curing room, some technical solutions have applied for Chinese patents, such as: No. ZL200410030848.5 "Scattered Leaf Stacked Tobacco Curing Room and Its Tobacco Leaf Curing Method", No. ZL200620135295.4 "General Reform Based on Natural Ventilation Dense Tobacco Curing Room”, No. ZL200820069376.8 “Cured Tobacco Airflow Translating Intensive Curing Room”, No. 200710077840.8 “Method for Curing Tobacco Leaves in an Intelligent Small-scale Intensive Curing Room” and No. 200920042876.7 “Tobacco Leaf Curing Room”, etc., but these patented technologies Generally, it can only reduce the amount of coal used, but not completely eliminate the use of coal

So far, there is no patent for the method of far-infrared curing tobacco leaves
