Description

Technical Field

[0001] The utility model relates to the technical field of cigar tobacco leaf curing, in particular to a cigar tobacco leaf curing barn. Background Art

[0002] As a special tobacco product, cigar is a special tobacco product made by hand-rolling after a series of technological processes for fresh tobacco leaves, including curing, fermentation and aging. Therefore, cigar tobacco leaves have strict requirements for curing humidity, temperature and air fluidity during the curing process.

[0003] As the main place for tobacco leaf curing, the cigar tobacco leaf curing barn must consider the adjustability of the internal humidity, temperature and air fluidity of the cigar tobacco leaf curing barn. At present, most of the designs of cigar tobacco leaf curing barns are relatively simple. The air fluidity is controlled by a fan and by adjusting the opening and closing size of the window, and the humidity and temperature are controlled by a humidifying device and a heating device. Although this can adjust the humidity, temperature and air fluidity of cigar tobacco leaves during the curing process, the power consumption is high, the production cost is high and the economic benefit is low during the curing process.

[0004] In addition, the internal temperature of the curing barn is uneven, which will affect the curing quality of cigar tobacco leaves. The reasons for the uneven internal temperature of the curing barn are as follows: on the one hand, because the density of hot air is small, the roof of the curing barn is exposed to the strongest solar radiation, and the roof temperature is also higher than that of the wall. Therefore, inside the curing barn, the temperature increases with height. On a sunny day in summer, the temperature difference between the upper and lower parts inside the curing barn is about 2-3 °C. On the other hand, during the day, due to the continuous change of the solar illumination angle, the solar radiation intensity received by each wall of the curing barn is different, which will cause the temperature difference of each wall of the curing barn, resulting in the temperature difference of the areas near different walls inside the curing barn.

[0005] The current structure of the cigar curing barn does not have a structure and equipment for adjusting the internal temperature uniformity. Therefore, there is still a technical gap in this aspect, and relevant personnel need to conduct research and improvement. Content of the Utility Model

[0006] The purpose of the utility model is to provide a cigar tobacco leaf curing barn, which can adjust the temperature and air fluidity in the cigar tobacco leaf curing barn by storing cold air, reduce the power consumption during the peak period of time-of-use electricity price, reduce the cost, improve the economic benefit, and can adjust the local temperature and reduce the temperature difference inside the curing barn.

[0007] A cigar tobacco leaf curing barn includes a curing barn main body. The key lies in that the curing barn main body is divided into an upper curing chamber and a lower gas storage chamber. A tobacco leaf curing rack is arranged in the curing chamber, at least one gas storage tank is arranged in the gas storage chamber, the outlet of the gas storage tank is communicated with the inside of the curing chamber through an air outlet, and the inlet of the gas storage tank is communicated with the outside through an air extraction pump.

[0008] The air storage tank extracts cold air at night for storage and releases the cold air into the curing room when cooling is needed at noon, etc., to cool the tobacco leaves and ensure that the temperature in the curing room is controlled within the optimal curing temperature range of the tobacco leaves. At the same time, it can reduce the electricity consumption during the peak period of time-of-use electricity price, reduce the production cost, and improve the economic benefit.

[0009] Further, the air storage tanks are arranged in an array in the air storage chamber;

[0010] Among them, the outlets of all the air storage tanks are communicated with the air outlet through the air outlet pipes, and on-off valves are arranged on the air outlet pipes; the inlets of all the air storage tanks are communicated with the main air inlet pipe through the branch air inlet pipes;

[0011] The main air inlet pipe is connected to the air outlet end of the air extraction pump, and the air inlet end of the air extraction pump communicates with the outside through an air extraction pipe.

[0012] By controlling the opening and closing of the on-off valves, the quantity and position of the cold air released from the air storage tanks can be controlled, the temperature difference in the curing room can be reduced, and the temperature can be controlled within the optimal curing temperature range of the tobacco leaves.

[0013] Further, one end of the air extraction pipe far away from the air extraction pump is successively provided with an insect-proof net, a desiccant, and a filter screen in the air inlet direction.

[0014] Further, the air outlet is arranged on the ground of the curing room.

[0015] Further, the air outlet is arranged on the wall of the curing room.

[0016] Further, the front and rear ends of the curing room have the same structure, and are both provided with an observation door, a ventilation window, a louver window, and a moisture exhaust window;

[0017] The two sides of the curing room have the same structure, and are both provided with a ventilation window and a moisture exhaust window.

[0018] Further, an exhaust fan is installed inside the louver window.

[0019] Further, a temperature sensor, a humidity sensor, a humidifying device, and a heating device are arranged inside the curing room.

[0020] Beneficial effects: The utility model can suck and store cold air at the low valley of the electricity price at night, and release the cold air during the peak period of the electricity price during the day to replace the cooling equipment to reduce the temperature in the curing room, reduce the electricity consumption during the peak period of the electricity price, reduce the production cost, and improve the economic benefit.

[0026] The specific implementation manners and working principles of the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] As Figure 1 shown, a curing barn for cigar tobacco leaves includes a main body of the curing barn, which is divided into an upper curing room 1 and a lower gas storage room 2. Among them, the curing room 1 is higher than the ground, and the gas storage room 2 is lower than the ground.

[0028] As Figure 3 shown, an observation door 16 is centrally arranged on the front of the curing room 1, and one ventilation window 11 and one moisture exhaust window 12 are arranged on both sides of the observation door 16. Among them, the moisture exhaust window 12 is directly above the ventilation window 11; two shutter windows 13 are arranged directly above each ventilation window 11, and an exhaust fan is installed inside the shutter windows 13;

[0029] The back of the curing room 1 has the same structure as the front of the curing room 1.

[0030] As Figure 4 shown, five groups of window combinations are arranged on the side of the curing room 1, and one vertically arranged ventilation window 11 and two moisture exhaust windows 12 are arranged inside the window combinations. Among them, the moisture exhaust windows 12 are above the ventilation window 11, and the center lines of one ventilation window 11 and two moisture exhaust windows 12 coincide;

[0031] The other side of the curing room 1 has the same structure as the above-mentioned side.

[0032] As Figure 1 shown, cigar tobacco leaf curing racks 15, air outlets 14, temperature sensors, humidity sensors, humidifying devices and heating devices are arranged inside the curing room 1;

[0033] Among them, the air outlets 14 are arranged on the ground of the curing room 1 and are arranged in an array; in addition, the air outlets 14 can also be arranged on the wall of the curing room 1.

[0034] As Figure 1 shown, 25 gas storage tanks 25 are arranged in the gas storage room 2, and the 25 gas storage tanks 25 are arranged in a 5×5 array;

[0035] The outlets of all the gas storage tanks 25 communicate with the air outlet 14 through the air outlet pipes 27, and the gas storage tanks 25 correspond to the air outlet 14 one by one; the inlets of all the gas storage tanks 25 are connected to one end of the main inlet pipe 23 through the branch inlet pipes 24, the other end of the main inlet pipe 23 is connected to the air outlet end of the air extraction pump 22, and the air inlet end of the air extraction pump 22 communicates with the outside through the air extraction pipe 21;

[0036] Among them, an opening and closing valve 26 is arranged on the air outlet pipe 27.

[0037] The curing barn 1 is of a cuboid structure. If the curing barn 1 is arranged in a north-south direction, in the morning, the east wall of the curing barn 1 will have a high temperature due to sunlight irradiation, resulting in a relatively high air temperature in the area near the east wall. At this time, the gas storage tank 25 corresponding to the opening and closing valve 26 in the area near the east wall is opened to release cold air, so that the temperature in this area is maintained at a suitable temperature for tobacco leaf curing. In the afternoon, the west wall will have a high temperature due to sunlight irradiation, resulting in a relatively high air temperature in the area near the west wall. At this time, the gas storage tank 25 corresponding to the opening and closing valve 26 in the area near the west wall is opened to release cold air, so that the temperature in this area is maintained at a suitable temperature for tobacco leaf curing.

[0038] If the curing barn 1 is arranged in an east-west direction, the south wall of the curing barn 1 will have a high temperature due to sunlight irradiation, resulting in a relatively high air temperature in the area near the south wall. The gas storage tank 25 corresponding to the opening and closing valve 26 in the area near the south wall is opened to release cold air, so that the temperature in this area is maintained at a suitable temperature for tobacco leaf curing. The north wall of the curing barn 1 will hardly be irradiated by sunlight all day, so the temperature of the north wall is relatively low, and the air temperature in the area near the north wall is also relatively low. The opening and closing valve 26 in this area remains closed. If the temperature is too low, it can also be heated by a heating device to keep the temperature in this area at a suitable temperature for tobacco leaf curing.

[0039] As Figure 1 shown, the end of the air extraction pipe 21 far from the air extraction pump 22 is higher than the ground, and an insect-proof net 211, a desiccant 212, and a filter net 213 are arranged in sequence in the air inlet direction.
