Description

Technical Field

[0001] The utility model belongs to the technical field of cigar tobacco leaf processing, and particularly relates to a cigar tobacco leaf curing barn. Background Technique

[0002] At present, due to the backward breeding, cultivation and modulation technologies, the supply of high-quality wrapper leaf raw materials is insufficient, which hinders the healthy development of the cigar industry. In the past, domestic curing barns mostly referred to burley tobacco and used simple curing barns for curing. In the past decade, in domestic cigar tobacco leaf production areas, the main feature of the curing barns in Hainan production area is that there are windows in the upper part of the curing barn and no windows in the lower part. Such curing barns are prone to poor ventilation in the lower part, local high humidity, and easy to occur mildew and rot. The main curing barns in Hubei production area are large open-plan curing barns with large areas and large capacities. The dehumidification and ventilation are carried out through a pipe placed at the bottom, which is not conducive to the control of the local curing environment, and is more unfavorable for the curing of high-quality cigar raw materials, especially high-quality wrapper leaves.

[0003] During the curing process of cigar tobacco leaves, due to poor ventilation and high humidity in the room, the tobacco leaves are extremely prone to mildew during the curing process. At the same time, the tobacco leaves may turn yellow slowly and unevenly in color, resulting in a significant reduction in the appearance and sensory quality of cigar tobacco leaves, a decrease in industrial usability, and serious economic losses.

[0004] The Chinese patent document with the publication number of CN204540786U discloses a special curing barn for cigar tobacco leaves. The curing barn body is composed of a wall and a roof. There is a tobacco curing rack in the curing barn body. There are ventilation doors and retractable moisture-keeping curtains on the wall. The wall is made of hollow bricks in a lattice pattern. The cross-section of the upper roof of the curing barn body is triangular, and the roof surface of the roof is composed of an outer greenhouse film, a middle thermal insulation cotton, and an inner sunshade net. According to the actual effect, it is found that this curing barn has the disadvantages of slow ventilation, no rapid ventilation setting, no moisture-keeping function of the wall, and no humidification in the curing barn.

[0005] The Chinese patent document with the publication number of CN110897183A discloses a solar cigar tobacco leaf curing barn with automatic temperature and humidity control. However, the position of the doors and windows in this structure will directly affect the tobacco leaves at the corresponding positions. The tobacco leaves in the place without windows will have poor ventilation, and the direct sunlight on sunny days at the window positions will change the curing effect. The excessive arrangement of the fans is likely to cause floating green on the cigar tobacco leaf wrapper that is sensitive to the air volume. The power-consuming equipment configured in the curing barn requires a large number of solar panels for power supply, and the cost of the curing barn is too high, which is not suitable for large-scale promotion in cigar tobacco leaf production areas.

[0006] The Chinese patent document with the publication number CN110810883A discloses a cigar tobacco curing barn. By taking advantage of the different natural temperature and humidity distributions in the upper, middle and lower parts of the multi-layer tobacco drying racks, the tobacco leaves in the withering and yellowing stage are hung on the 1st - 2nd layers, the tobacco leaves in the browning stage are hung on the 3rd - 4th layers, and the tobacco leaves in the stem-drying stage are hung on the 5th - 6th layers. The temperature and humidity of the curing barn are controlled by an automatic control system. However, this structure has too many layers, increasing the operation difficulty and danger inside the curing barn. At the same time, when the fan is installed on the top layer for regulation, it only affects the upper space, resulting in a large wind speed, which has an impact on the curing of the upper-layer tobacco leaves. The lower space is a high-humidity area, often with a small wind speed or even no wind, and the ventilation and moisture removal effects are not good.

[0007] In view of this, how to provide a cigar tobacco curing barn that can achieve rapid ventilation inside the curing barn, and at the same time has functions of moisture retention, humidity control, heat preservation and light shading, so as to provide a guarantee for the production of high-quality cigar tobacco, is a technical problem urgently to be solved in this field.

[0034] Please refer to Figure 1-6, this application provides an embodiment of a cigar drying house, including: a frame 1, a roof 2 covering the upper part of the frame 1, and a side enclosure 3 and a door 4 connected to the frame 1; the side enclosure 3 includes a moisture retention layer 31 and a ventilation and light-shielding layer 32 arranged in sequence from the inside to the outside; the moisture retention layer 31 is disposed on the frame 1 in a retractable manner, and the ventilation and light-shielding layer 32 is composed of a light-shielding material that does not affect ventilation; the door 4 and the roof 2 and the side enclosure 3 jointly enclose a drying space. Unless otherwise specified, the following "inner side" refers to the side close to the drying space, and the "outer side" refers to the side far from the drying space.

[0035] The drying space of this application is enclosed by a roof 2, a side enclosure 3, and a door 4 installed through the frame 1. Among them, the side enclosure 3 is provided with a moisture retention layer 31 to increase the moisture retention and water locking ability, and ensure the drying quality of cigar tobacco leaves. The moisture retention layer 31 is retractable, which is convenient for quickly retracting the moisture retention layer 31 when the humidity in the drying space is too high, so as to achieve rapid ventilation and dehumidification. The ventilation and light-shielding layer 32 of this application can ensure the shading in the drying house while quickly ventilating after the moisture retention layer 31 is retracted, avoid direct sunlight on the tobacco leaves, and ensure the quality of cigar tobacco leaves.

[0036] In this embodiment, the moisture retention layer 31 is disposed on the frame 1 through an electric lifting roller shutter to quickly lift and lower the moisture retention layer 31 to achieve retraction. In other embodiments, manual retraction, side retraction and other setting methods can also be used.

[0037] As Figure 4 The side view of the moisture retention blanket, in this embodiment, the moisture retention layer 31 includes a moisture retention blanket, and the moisture retention blanket includes a fixing layer 311 for maintaining the shape, and moisture retention materials 312 connected to both sides of the fixing layer 311 by stitches. Among them, the fixing layer 311 can be selected from fixing layer materials such as polyester fiber, nylon, etc. with good wear resistance, wrinkle resistance, air permeability, moisture resistance and relatively high strength, which can withstand a certain tensile force and maintain the shape stability. The fixing layer 311 can effectively support the moisture retention layer 31 and maintain the stability of the overall structure. The moisture retention materials 312 can be selected from cotton fiber, bamboo fiber, polyester fiber, geotextile, etc., which have good moisture absorption and air permeability, and can effectively absorb and retain moisture to provide continuous humidity for the drying house. This moisture retention blanket has good heat preservation and moisture retention effects and easy retractability. Specifically, the fixing layer 311 in this example is polyester fiber, and the moisture retention material 312 is cotton fiber. This moisture retention blanket is light in weight and suitable for the structure of this application that is only supported and loaded by the frame 1.

[0038] The applicant found that to quickly increase and adjust the humidity in the drying space, in addition to humidifying the air inside the drying space, it is also crucial to quickly humidify the moisture retention layer 31. Therefore, in this embodiment, as Figure 4Side view of the moisture-preserving blanket. Water-storing cotton 313 is connected to both sides of the moisture-preserving blanket by sewing. The cigar drying house further includes a moisture layer humidifying device 5, which includes a water tank and a water pump that can send the water in the water tank to the water-storing cotton 313. Through the water-storing cotton 313 and the moisture layer humidifying device 5, the moisture layer 31 can be humidified directly and quickly, and in combination with other humidifying means, the humidity in the drying space can be quickly increased. In this embodiment, the water-storing cotton 313 is arranged in evenly distributed horizontal strips and is sewn on both sides of the moisture-preserving material 312.

[0039] In this embodiment, the light-shielding material is light-shielding cloth. The light-shielding cloth has both light-shielding and breathable functions and blocks external light through weaving technology or coating treatment. The light-shielding cloth can be selected from materials such as polyester and cotton-linen blends. In other embodiments, the light-shielding material can also be selected from light-shielding boards, light-shielding films, etc. The light-shielding cloth is light in weight and is suitable for the structure of this application that is only supported and loaded by the frame 1.

[0040] In this embodiment, the light-shielding material is polyester light-shielding cloth, which is hung on a crossbar, that is, connected to the frame 1 through the crossbar. In other embodiments, the light-shielding cloth can also be connected to the frame 1 through an electric lifting rolling shutter, which is convenient for regularly ventilating and exposing the drying space to the sun.

[0041] As Figure 5 , in this embodiment, the door 4 is a fully open sliding door that can completely open one side wall of the drying space. Its fully open state is as Figure 5 . Completely opening one side wall of the drying space is beneficial for further rapid ventilation. The sliding door has better sealing performance compared to the hinge door.

[0042] Preferably, a second moisture-preserving material 41 that moves with the door 4 is provided inside the door 4, which is beneficial for maintaining the moisture-preserving performance of the drying space on one side of the door 4 when it is closed. The second moisture-preserving material 41 can be the same as or different from the moisture-preserving material 312, and can also be connected to the door 4 or be independently arranged from the door 4. In this embodiment, as Figure 6 , the second moisture-preserving material 41 is cotton fiber attached to the inside of the door 4.

[0043] As Figure 5 , preferably, a second light-shielding material 42 that does not move with the door 4 is provided inside the door 4 to block the sunlight in the direction of the door 4 when the door 4 is opened. The second light-shielding material 42 can be the same as or different from the light-shielding material, and can also be connected to the door 4 or be independently arranged from the door 4. In this embodiment, the second light-shielding material 42 is a light-shielding cloth independently and liftably arranged inside the door 4 through an electric lifting rolling shutter, which is convenient for personnel to enter and exit.

[0044] In this embodiment, a ventilation opening 21 is provided at the top of the roof 2, and a fan is provided inside the ventilation opening 21. The top ventilation method is similar to the conditions of natural drying, which can reduce forced ventilation, make the humidity in the entire drying house more uniform, and better meet the needs of cigar drying.

[0045] In this embodiment, the side wall 3 further includes an anti-theft wire mesh layer 33 provided outside the ventilation and light-shielding layer 32 for anti-theft and certain support.
