Abstract
In order to solve the problems of poor quality and serious pollution in the conventional tobacco flue-curing and realize the informationized management of tobacco flue-curing workshops, the invention discloses a natural gas heating circulating airflow tobacco flue-curing chamber. In the technical scheme, a combustion chamber is arranged outside the flue-curing chamber; a natural gas combustion furnace, an air heat exchanger and a temperature controller are arranged in the combustion chamber; a circulating fan is arranged at an air inlet between the flue-curing chamber and the combustion chamber; a smoke exhaust channel and a humidity-discharging opening are formed in the flue-curing chamber; a temperature sensor and a humidity sensor are arranged in the flue-curing chamber; and a tobacco frame is arranged in the flue-curing chamber. In the natural gas heating circulating airflow tobacco flue-curing chamber, central heating is performed by using natural gas, the temperature control accuracy of each flue-curing house is improved, the intensive flue-curing house is heated flexibly, discharges humidity smoothly and is convenient to operate; flue-cured tobaccos are full in color and luster and uniform in colors, the influence on the quality of the flue-cured tobaccos due to artificial error is avoided, the grade of the flue-cured quality of the tobaccos is improved, the natural gas serving as clean energy is used, and environmental pollution is reduced.
Description
Technical field
The present invention relates to a kind of tobacco flue-curing chamber, specifically a kind of natural gas heating circulating airflow tobacco flue-curing chamber that utilizes belongs to the agricultural byproducts processing field.
Background technology
Mature Tobacco Leaves will in time carry out drying after plucking results processes, traditional drying tobacco processing method is at source to utilize the coal stove Self-dry by the tobacco grower, because the tobacco grower grasps the difference of baking technology level, can make a big impact to Tobacco Product Quality, is difficult to the credit rating that reaches higher.In recent years, China actively promotes in the area that tobacco planting is concentrated and utilizes bulk curing barn to concentrate baking, the index of correlation such as equipment level of processing, barn build guality, method for flue-curing tobacco leaves, baking quality of tobacco, baking energy consumption of bulk curing barn has been had significantly improve, make the quality of tobacco grade obtain certain raising.But when building a large amount of bulk curing barns and curing barn cluster, some have also occurred and needed to be resolved hurrily and improved problem.At first be that environmental pollution is serious, because the concentrated construction of barn, the little Combustion of Hot Air Furnace of existing by hand coal is insufficient in addition, give off a large amount of black flue dust, when tens even a hundreds of baking oven chimney when discharging simultaneously flue dust and flue gas, can form a large amount of black or yellow smogs in flakes, directly have influence on peripheral villager's health; Badly influence the normal growth of crops; Next is complex procedures in the Tobacco Leaf Curing, and recruitment is more, compiles before baking the cigarette, makes a fire, fills cigarette in the flue-cured tobacco process and smoke still takies a large amount of labours; Moreover tobacco leaf to dry by the fire used little hot-blast stove coal combustion insufficient, the thermal efficiency is low, so the coal resources consumption is very big, it is estimated, the annual tobacco flue-curing of China consumes coal up to 3,500,000 tons, serious waste of resources.
Summary of the invention
In order to overcome the problems referred to above that exist in the present tobacco flue-curing; reduce greenhouse gas emission; reduce Fossil fuel consumption; realize low-carbon (LC) tobacco flue-curing; the to protect mankind living environment; realize the information system management at tobacco flue-curing workshop, advance the development process of China's modern tobacco agriculture, the invention discloses a kind of natural gas heating circulating airflow tobacco flue-curing chamber.
The present invention takes following technical scheme to implement to finish:
The baking vessel that several orderings of concentrated setting are consistent, outside each baking vessel, the combustion chamber is set, combustion furnace, air heat exchange machine, temperature controller are set in the combustion chamber, natural gas line is connected with combustion furnace, install natural gas valve between natural gas line and the combustion furnace, have air inlet between baking vessel and the combustion chamber, air inlet is provided with circulating fan, baking vessel is provided with discharge flue and moisture exhausting port, baking indoor set temperature inductor and humidity sensor, the baking vessel both sides are respectively equipped with observation window and baking vessel's door, and what the tobacco leaf frame was orderly is positioned in the baking vessel.
The present invention is owing to adopting the natural gas central heating, each bakery temperature control precision improves, dense roasting room heats up flexibly, and hydrofuge is smooth and easy, convenient operation, the tobacco leaf color and luster is full after the baking, the leaf color uniformity avoids the people to affect flue cured tobacco quality for fault, has conscientiously improved the baking quality grade of tobacco leaf, use the clean energy resource natural gas, reduced environmental pollution.
