Background technology

Tobacco flue-curing house is indispensable basic equipment in cured tobacco production.Tobacco flue-curing house, after interior baking modulation, just shows the distinctive color of flue-cured tobacco, type, becomes the quality raw materials meeting cigarette industry needs.Its general principle is after tobacco leaf is heated, and the moisture (Mature Tobacco Leaves water content about about 85%) in tobacco leaf is discharged, and is discharged outside tobacco flue-curing house, thus makes tobacco leaf scalding, drying after moisture vaporization.

Current intensive tobacco curing is mainly built with clay brick or cement brick, the major defect that this mode exists is poor thermal insulation property, construction cost is high, quality is difficult to ensure card and energy consumption cost is high, in prior art when tobacco flue-curing house structure does not make essence change, above-mentioned defect can only be overcome by alternate manner, the arrangement of such as tobacco leaf (peg, thread a needle) improves baking quality, and the mode of heating of tobacco flue-curing (such as burn coal, burn natural gas, even infrared, air energy heat pump etc.) reduces energy consumption cost.But government and tobacco company all will drop into huge fund every year and transform rural area barn, also can leave over down the superseded barn put aside as useless after changing tobacco planting district, this not only adds cost and also wastes land resource, is unfavorable for the sustainable development of tobacco business.

Based on the problems referred to above, the feasible program that some can overcome the problems referred to above has been proposed in prior art, such as publication number is that the Chinese patent literature of CN202819587U discloses one " detachable tobacco flue-curing house ", the room body of this tobacco flue-curing house is made up of combined wall panel, be provided with in drying room multiple can along the cigarette frame of rail moving, the dividing plate fixing blower fan is installed above the radiator in heating clamber, dividing plate is placed between uptake and lower air port, a long limit of dividing plate is connected with partition wall, two minor faces of dividing plate are connected with combined wall panel, fan outlet is connected with the uptake of partition wall is through by transition conduit.When the main crop rotation in tobacco planting district, by mobile for tobacco flue-curing house dismounting, the waste of land resource can be avoided.

Current so-called portable tobacco flue-curing house is only that tobacco flue-curing house (even combustion chamber) can be dismantled, have cost-saving, account for soil less, reduce the advantage such as energy consumption and mobile restructuring, the intensive flue-cured tobacco room of the brick mix structure such as clay brick or cement brick barn can be replaced.

However, still there are problems in the baking of tobacco leaf, such as: 1, fill cigarette, hang cigarette, get the artificial carrying turnover tobacco flue-curing house repeatedly of cigarette process need, this process compares waste of manpower cost, reduces operating efficiency; 2, the amount of flue-cured tobacco is limited to the size of tobacco flue-curing house, want the amount improving flue-cured tobacco, just need to change the volume increasing tobacco flue-curing house or the quantity increasing tobacco flue-curing house, cost obviously has several times increase, production efficiency there is no lifting in essence, thus affect productivity effect.
