Background

Burley tobacco is a raw material of blended cigarettes, and can also be used for cigars, pipe tobacco and chewing tobacco; the main vein is thicker, the water content is higher, the leaves are thin and light, the tissue structure is loose and not coarse, and the elasticity is strong; high filling value and good perfume absorbing performance. Burley tobacco belongs to air-cured tobacco, and the curing is carried out in an air-cured room, and the tobacco leaves are dehydrated, discolored and dried by utilizing air convection, and the contained substances are simultaneously converted. The modulation method is to hang the mature tobacco leaves in a drying room or a drying shed for drying until the mature tobacco leaves are dried, the drying is divided into three stages (namely a color changing period, a color fixing period and a tendon drying period), the drying time is generally 40-50 days, and the method is an important link for forming the quality of the burley tobacco. The existing air-curing house is mainly an 89-type three-layer air-curing house, the number of layers of the air-curing house is too high, the safety risk is high when cigarettes are hung up and down, and the air-curing house is particularly not friendly to middle-aged and old tobacco growers. The air-curing house generally dries burley tobacco leaves in different curing stages in a closed space, increases the difficulty of temperature and humidity control, and often causes the tobacco leaves to mildew in the stem drying period in continuous rainy days. The air-curing house has single use function, so that the actual use cost is higher.

In the prior art, for example, chinese patent application CN112006320A provides a vitrification sun-curing house and a curing method for curing tobacco leaf raw materials of a heated cigarette, wherein a heat insulation plate is arranged at the bottom of the sun-curing house, and a hot air blower, a humidifying atomizer, a kowtow smooth surface and an electric sunshade net are arranged at two sides of the sun-curing house. For example, the chinese granted patent CN203072865U provides a dedicated air-curing room for burley tobacco modulation test, wherein the top and the side surfaces of the room are respectively provided with a light-transmitting plate, and the temperature and humidity are controlled by an exhaust fan, a heater and a humidifier. However, these air-curing houses cannot be adapted to burley tobacco, or the burley tobacco leaves in different stages are hung in one air-curing house for air-curing, and the air-curing house is not designed according to the special air-curing requirement of the burley tobacco leaves in the stem drying period; moreover, the air drying rooms adopt more electronic automation equipment, and are single in use function and high in cost.

The flexible and easily-curled wall body is rolled upwards manually or is rolled upwards by using a film rolling device. The film rolling device is common equipment on the market, is commonly used for automatic film rolling operation of the agricultural greenhouse film, and the equipment structure can also refer to the common rolling gate structure.

Preferably, the bottom of the curtain plate is provided with at least one weight.

More preferably, the weight member is detachably provided on the curtain plate. For example, the weights may be taped to the slats, or pockets may be provided in the slats, with the weights being received in the pockets, or any other form that is easily removable may be used.

The effect of the weight piece is to ensure that the curtain plate can cover the air outlet to a certain degree when the temperature in the air-drying room is in a bottom-crossing state and air convection is not needed, and to form stress balance between the hot air convection and the thrust generated by the hot air, and the opening and closing angle of the curtain plate is controlled by increasing or reducing the weight piece, so that the flow speed of air circulation flow is controlled. The weight pieces can be in a strip or block structure, and the number of the weight pieces made of light materials such as wood, plastics and the like can be selected according to the opening and closing angle of the curtain plate to be controlled. The heavier/more numerous the weight members, the smaller the upward opening and closing angle of the shutter slats.

Preferably, the second wall is higher than the first wall. The second wall is higher than the first wall so as to collect more sunlight energy to be reflected and remain in the airing house.

More preferably, in actual production, the height of the second wall is preferably 3m, and the height of the first wall is preferably 2m.

Preferably, a heat insulation layer is further arranged below the bottom plate. The heat insulating layer can further prevent heat loss.

Compared with the prior art, the beneficial effects of the utility model are that: the air-curing house has a simple structure and can effectively shorten the rib drying period of the burley tobacco; through the design of six surfaces of the airing house and the utilization of the circulating convection generated by heating the air in the airing house by sunlight, the illumination per unit area is increased by more than 30 percent, thereby improving the water vapor diffusion speed in the airing house and shortening the original 21 to 25 days of the burley tobacco to 10 to 15 days; the modulation density of the tobacco leaves in the dry stem period of unit area can be increased by two times; the air-drying house can be used as an air-drying house and a seedling raising pool for floating seedling raising, so that the use efficiency of the air-drying house is increased, and the construction cost of facilities is flattened; by reducing the height of the airing room, the working height of the burley tobacco during airing is reduced from 3.6m originally to reach the tentacle, and the safety risk in burley tobacco production is greatly reduced.
