Description

Technical Field

[0001] The utility model relates to the field of flue-cured tobacco baking control, in particular to a novel precise moisture regain device for a baking room. Background Art

[0002] The moisture recovery of tobacco leaves after curing is an important part of the tobacco curing process. Its efficiency and effect have a great impact on the quality, yield and utilization rate of tobacco leaves after curing, especially when the climate is dry and the number of curing rooms is insufficient. The moisture content of tobacco leaves after curing is generally 5% to 7%, which is very easy to break, and it is not convenient for the subsequent operations such as uncuring, unpiling, stacking and grading. Therefore, the tobacco leaves must be treated with moisture recovery after curing to make the moisture content of the tobacco leaves reach 12% to 14%, and the tobacco leaves are slightly softened before uncuring, unpiling, stacking and other operations are carried out to ensure that the quality and yield of the tobacco leaves are not lost.

[0003] In order to increase the humidity after baking and quickly increase the water content of the tobacco leaves after baking, a new type of precise moisture regain equipment in the baking room is needed.

[0004] Currently, natural rehumidification or ultrasonic humidifier rehumidification is usually used for rehumidification of tobacco leaves after curing. Natural rehumidification is to open all the doors and windows of the dense curing room, and the tobacco leaves absorb moisture from the outside air to increase their water content. This method is subject to weather conditions and it is not easy to control the appropriate degree of rehumidification. Ultrasonic humidifier rehumidification is to use ultrasound to atomize water and spray it into the curing room for rehumidification. In this method, the water is not vaporized, but still enters the curing room as liquid, which is easy to adhere to the nearest tobacco leaves, making the tobacco leaves unevenly rehumidified, and failing to utilize the residual heat after curing, and the economic benefit is not high. Therefore, a new type of precise rehumidification equipment for curing rooms is proposed to solve the above problems. Utility Model Content

[0033] Working principle: When you want to quickly increase the humidity in the oven, turn on the rotating motor 8, the output shaft at the top of the rotating motor 8 drives the threaded rod 6 to rotate, the threaded rod 6 drives the threaded block 5 to rise, and the threaded block 5 drives the evaporation frame 4 to rise until the evaporation frame 4 completely blocks the return air outlet. At this time, open the solenoid valve of the water tank 10, and the clean water inside the water tank 10 falls into the water storage tank 11 through the hose 9 under the influence of gravity. The water in the water storage tank 11 is absorbed by the water absorption block 14 and transferred to the humidification plate 13 by rotating the water absorption rod 12, and the intensive oven circulation is started. The fan closes the cold air inlet door to put the curing room in an internal circulation state, and uses the flowing air through the return air port and the residual heat inside the curing room to penetrate the humidifying plate 13 to take away the gaseous water, increase the humidity of the air, and form air with relatively high humidity. When the tobacco leaves are dried by circulating through the tobacco loading chamber, the tobacco leaves have good hygroscopicity, so they absorb water to increase their own water content. The relative humidity of the air after the dried tobacco leaves absorb moisture is therefore reduced, and the gaseous water is again taken away from the return air port Penetrate the humidifying plate 13 to increase the humidity of the air, and this process is repeated to increase the moisture content of the tobacco leaves. When the humidification amount is desired to be controlled, the electric push rod 23 is turned on, and the telescopic end at the right end of the electric push rod 23 drives the connecting bracket 22 to move left and right, and the connecting bracket 22 drives the connecting rod 21 and the connecting block 20 to move left and right, and the connecting block 20 drives the rack 17 to move left and right, and the rack 17 drives the rotating gear 16 to rotate, and the rotating gear 16 drives the humidification plate 13 to rotate through the rotating shaft 15, and the humidification plate 13 will block the evaporation frame 4, control the ventilation area of ​​the evaporation frame 4, and reduce the return air volume, thereby achieving the effect of controlling the humidification degree.
