Description

The continuous tobacco curing barn of solar energy subregion

Technical field

The invention belongs to the processing of farm products field, relates to baking equipment for preparatory treatment of tobacco, proposes the continuous tobacco curing barn of a kind of solar energy subregion.

Background technology

1, traditional tobacco curing barn is the room formula building that assembles with sun-dried mud brick or masonry, the air channel, ground is left in the bottom of perimeter walls, the highest point of ridge or wall leaves skylight or upper exhaust passage, one end of indoor backer's wall is built the stove that has for coal combustion, the indoor fiery ridge and the chimney that goes out wall that has for the hot gas cycle full chamber heating of stove.Be carved with groove on indoor two eaves walls, purlin is equipped with in the centre in room, can hang over after small bamboo on groove one end and purlin for tobacco leaf.After bright cigarette is filled barn, light a fire and heat, first little fire, rear moderate heat, then big fire.First block lower air duct, then adjust and open upper lower air duct, block again at last.Make that tobacco leaf is wilting, flavescence, cured leaf, dried muscle again, be roasted into smoke through an a heatable brick bed cigarette after 4-5 days.Whole bake process with people's sensation and experience, so the cigarette quality that bakes is difficult for assurance, or is baked green grass or young crops or roasting black entirely, or dust.Flue cured tobacco quality can't guarantee in a word, energy resource consumption, and roasting one kilogram of dried cigarette needs 2.5 kilograms of coals.

2, in recent years, the barn of cigarette has very much progress, and as Canadian " close-packed tobacco barn ", its space availability ratio improves a lot.The dried cigarette quantity that bakes of every cubic metre is more than 5 times of traditional baking chamber.Be to force Wind Volume to ventilate with traditional baking chamber than it, with coal, aqueous medium heated, then by heat exchanger with air heat.The wet and dry bulb temperature instrument of sensing is housed in barn, and can be according to the size of humidity automatic control heat supply and ventilation.Coal can be saved the dried cigarette of each kilogram and consume 1.5 kilograms of coals.But this barn is also to fill a cigarette to need baking in 4-5 days just can go out dried cigarette, due to the Wind Volume forced ventilation, the air that aroma substance in fresh tobacco leaf is flowed has blown away, so the fragrance that flue-cured tobacco is strong is thin out, the attenuation of blade identity, and the quality of the cigarette that bakes is bad, because large-scale dress cigarette clip has substituted pole on artificial volume cigarette, tens kilograms of the bright cigarettes of every secondary cigarette clip, be afraid of that again smoked sheet drops in the flue-cured tobacco process, so the cigarette folder is very tight to bright cigarette folder, causes Wind Volume to pass through, and meat muscle phenomenon often occurs.

Summary of the invention

The applicant is in the manufacturing business activities of being engaged in for many years the tobacco planting processing equipment, find that traditional tobacco curing barn and close-packed tobacco barn exist certain defect, the personnel of organizational technology are through constantly exploring and improving, purpose is to provide a kind of solar energy subregion continuous tobacco curing barn, can utilize energy-saving solar, can divide the section temperature control wet baking, improve Flue-cured tobacco Quality, can work continuously, enhance productivity.

the technical scheme that the invention is taked is the continuous tobacco curing barn of a kind of solar energy subregion of design, its structure comprises: barn, comprise that hot-water boiler and solar water heater unite by the heat exchanger heating system, comprise the air channel, ventilation fan, moistureproof window, the ventilating system of humidifier, the tobacco leaf holder suspension mechanism, wherein, described barn adopts composite insulation boards to be assembled into bending tunnel-like barn, and the observation road between the tunnel, described bending tunnel-like barn is divided into some sections: comprise 1. tobacco leaf pretreating zone, 2. blade flavescence district, 3. offshoot flavescence district, 4. master pulse flavescence district, 5. fragrance is synthetic distinguishes, 6. dried muscle district and 7. moisture regain district, wherein said heating system adopts 1., 2., 3., 4., 5. heat exchanger is located at described section bottom in section, the ventilation fan of described ventilating system is contained in described section top, wind passage mouth is located at the bottom, at 6. section, heat exchanger is located at this section top, moistureproof window is located at this section bottom, and ventilation fan is located on this section sidewall, at suitable section two ends respectively and air curtain is set between adjacent sections, be provided with the moisture regain humidifier at 7. section, wherein said tobacco leaf holder suspension mechanism adopts at the end to end track of bending tunnel top fixing suspention C type, along stretching tobacco leaf frame link under the chain of track.

Described moistureproof window is communicated with to the humidification port of relevant section by pipeline.

technique scheme and measure are adopted in the invention, to existing " close-packed tobacco barn " in addition larger improvement, due to barn design bending tunnel-like barn, can realize producing continuously with fashionable dress cigarette, smoke, enhance productivity, tobacco flue-curing season is the very strong time of the sun just, owing to having utilized solar energy and boiler combined heat, solar water heater efficient is very high, except cloudy day, evening, the period such as rain use hot-water boiler, the coal consumption amount of one kilogram of dried cigarette is dropped to below one kilogram, saved the energy, due to curved tunnels shape barn is divided into some sections roasting between, be convenient to respectively by regulating and controlling temperature, humidity, air quantity, wind speed, can follow the plant characteristic of tobacco leaf and the quality requirements of flue-cured tobacco, segmentation divides the order baking, thereby guarantee the quality of flue-cured tobacco, significantly improve as color and luster, fragrance, identity etc., increased tobacco grower's income, and provide quality raw materials for tobacco product, due to heat supply, the heat exchanger of ventilating system, ventilation fan, wind passage mouth, the Reasonable Arrangement of moistureproof window and air curtain, and relevant parameter is set, not only take full advantage of heat energy, rheumatism, and be convenient to realize automatic control, because the tobacco leaf holder suspension mechanism adopts the C type end to end track consistent with the tunnel-like barn, along stretching tobacco leaf frame link under the track chain, not only filling the cigarette smoke can carry out outside barn, easy and simple to handle, improved working condition, alleviated labour intensity, and replace artificial pole or the large-scale dress cigarette clip on cigarette of compiling with tobacco leaf frame link, tobacco leaf each position is evenly ventilated, dried by the fire or got damp again, Flue-cured tobacco Quality and presentation quality have further been improved.In a word, the continuous tobacco curing barn of this solar energy subregion of the invention, compare with traditional tobacco curing barn or the external close-packed tobacco barn of introducing, have continuous production, energy savings is convenient to control, improve working conditions, the science flue-cured tobacco effectively improves and guarantees the flue-cured tobacco product quality, and then increases the remarkable advantage such as peasant income.
