Abstract
The utility model provides an air descending type bulk curing barn which is mainly composed of a curing chamber and a control device. A wall body which is opposite to a furnace (5) is provided with an air inlet, an air inlet passage (2) which is communicated with the air inlet (1) is arranged at the inner bottom of the chamber, a circulating fan (3) is arranged above the air inlet passage, the air inlet is provided with an electric air door, a wall body of the furnace which is adjacent to the air inlet is provided with a standby air inlet (12), and at the same time, a wall body which is arranged at the opposite side of the standby air inlet is provided with an air outlet (11); a bottom dragon (4) is communicated with the furnace, a second dragon and a third dragon are both arranged above the bottom dragon with one end being communicated with the bottom dragon and the other end being bended downward to be communicated with a chimney (8), and the circulating fan is arranged just below the bottom dragon. The air descending type bulk curing barn has simple structure, can carry out reconstruction on the basis of the prior ordinary curing barn, and is easy to be popularized in rural areas. By adopting forced heated air circulation, the fume loading amount of the curing barn can be increased by 2.5 to 3 times. The curing barn is suitable for being installed an automation curing system to avoid the bad curing fume phenomenon caused by improper manual operation.
Description
Technical field
The utility model belongs to the tobacco flue-curing technology, mainly proposes a kind of air-flow descending manner bulk curing barn.
Background technology
The research of bulk curing barn starts from mid-term the 1950's.It is purpose that people such as the upright Jonson of university of North Carolina, USA manually drop into, improve flue cured tobacco quality with minimizing tobacco flue-curing, has carried out intensive baking (bulk-curing) experimental study, thereby has caused a revolution of tobacco flue-curing technology.In latter stage in 20th century, the research of bulk curing barn begins to rise in China, and along with popularizing of electronic product, the automation flue-curing device also begins in the whole nation to promote.
By investigation to domestic existing barn, have to be the frame mode of gravity-flow ventilation hydrofuge about 90%, this frame mode has the following disadvantages in actual use: (1) dress cigarette amount is few, can not realize the densification baking; (2) can not realize the automation baking; (3) bake process labour intensity is big.Though other has the barn about 10% to pass through the densification transformation, also has the following disadvantages: (1) firing equipment unreasonable structure is unfavorable for making full use of of heat energy; (2) position of sound production of hot air circulation blower is unreasonable, is unfavorable for hot air circulation; (3) it is bigger influenced by power failure.
Summary of the invention
The purpose of this utility model is to propose a kind of air-flow descending manner bulk curing barn, by the improvement to the barn structure, overcomes the existing existing above-mentioned defective of barn.
The utility model is finished the technical scheme that its invention task taked: it mainly is made of baking vessel and control device, on the body of wall relative, has air inlet with burner hearth, and the air intake duct that is communicated with air inlet is set in indoor bottom, circulating fan is set above air intake duct, air inlet is provided with MOD, on the burner hearth body of wall adjacent, standby air inlet is set, on the body of wall of standby air inlet offside, sets out the air port simultaneously with air inlet.The humidity that control device is measured according to wet bulb sensor is controlled electronic shutter and is opened, and air intake duct forms negative pressuren zone, and extraneous air is introduced, and circulating fan upwards blows air to the opposite air outlet, discharges damp-heat air; End dragon is communicated with burner hearth, and two dragons, three dragons all are positioned at dragon top, end one end and are communicated with end dragon, and the other end bends the back downwards and is connected with chimney, and this structure is beneficial to making full use of of heat energy; Circulating fan be positioned at end dragon under, make heated hot blast stream thus under the effect of circulating fan, from bottom to top, more from top to bottom in indoor formation circulation.Open can natural hydrofuge for standby air inlet when having a power failure, when having a power failure to reduce to the influence of flue-cured tobacco.
The beneficial effects of the utility model are: 1, described barn is simple in structure, can reconstruct on the basis of original traditional flue-curing barn, and newly-built cost is not high yet, probably about 2000, is easy to promote in the rural area.2, described barn adopts forced hot air circulation, and barn dress cigarette amount can be brought up to original 2.5-3 doubly.3, barn be fit to be installed the automation baking system, has avoided causing because of manually-operated is improper roasting bad cigarette phenomenon.4, described end dragon, two dragons and three dragons is rational in infrastructure, and heat energy is made full use of.5, it is very little influenced by power failure, and opening standby air inlet after the power failure can natural hydrofuge.
