Description
Technical Field
[0001] This utility model relates to the field of tobacco processing equipment, specifically to a tobacco bale rehumidification shed. Background Technology
[0002] Tobacco leaves are a type of commodity whose moisture content is easily affected by external climatic conditions. The moisture content not only affects the physical properties of tobacco leaves, such as weight, breakage resistance, and filling power, but also influences the subsequent aging and fermentation processes, thus affecting the color, aroma, and flavor of the tobacco leaves. If the moisture content of the tobacco leaves is too low, they will easily break, increasing losses during subsequent cigarette processing. Therefore, the rehydration process of tobacco leaves is crucial. Currently, during tobacco rehydration, workers place tobacco bales on racks and use rehydration devices and pipes to spray hot steam onto the tobacco leaves to increase their moisture content. However, existing rehydration devices have the following drawbacks:
[0003] (1) The tobacco packs were stacked on the frame, and the steam was not sprayed in all areas, resulting in uneven moisture reabsorption of the tobacco leaves.
[0004] (2) Water vapor rises to the top of the shed and condenses. Over time, water droplets will drip from the top of the shed, causing excessive moisture in the upper tobacco leaves and affecting the rehumidification effect. Utility Model Content
[0005] To address the aforementioned issues, this application proposes a tobacco pack rehumidification shed, comprising a shed body, a frame, a rehumidification device, and a pipe assembly; the shed body is enclosed and its top is inclined to prevent the external environment from affecting the interior space, and a drainage device is provided at the top of the shed body to guide water droplets from the top of the shed body to collect and flow down.
[0006] The frame includes multiple shelves evenly arranged, each shelf is hollowed out and cigarette packs are evenly placed on each shelf, with the cigarette packs distributed in a single layer on the shelf.
[0007] The rehumidification device is connected to the pipe assembly. The rehumidification device is used to monitor the ambient humidity and temperature and can spray hot steam to humidify the tobacco leaves.
[0008] The tube assembly includes multiple sets of humidifying tubes, which are wound around each layer of the frame. The humidifying tubes are equipped with nozzles for spraying hot and humid gas into the tobacco pack.
[0009] Preferably, the bottom of the frame is meshed, and each layer of the frame is evenly placed with a layer of smoke packs to prevent the smoke packs from piling up and causing the interior to be unable to humidify or to have a poor humidification effect. Setting the bottom of the frame as mesh facilitates the flow of hot steam and increases the humidification effect.
[0010] The rehumidification device includes a control component, a steam injection component, and a hot air component, with the control component connected to the evaporative jet component and the hot air component.
[0011] Preferably, the humidifying pipes are wound from the bottom of the shelf towards the top, with the humidifying pipe distribution area at the bottom of the shelf being larger than that at the top, and the shelf being detachable from the humidifying pipes.
[0012] Alternatively, the pipe assembly can be located on both sides of the frame, with humidifying pipes installed on both sides of each layer of the frame. Alternatively, humidifying pipes can be installed around the perimeter of each layer of the frame. The steam emitted by the humidifying pipes can be evenly distributed, which is beneficial for the uniform humidification of the tobacco leaves.
[0013] Preferably, the frame includes a frame and shelves, the frame is provided with a horizontal track, and the shelves are connected to the track and can move along the track.
[0014] Preferably, the frame and the shelves are connected by a drawer, and the shelves slide within the track.
[0015] Preferably, the water vapor ejected from the nozzle is distributed in a fan shape, increasing the jet area and making the water vapor distribution more uniform;
[0016] Preferably, the nozzles of the humidification pipe located at the bottom of the shelf spray direction are horizontal to increase the contact area between the hot steam sprayed from the nozzles and the bottom of the shelf.
[0017] Preferably, the number of nozzles on the humidification pipe gradually decreases from low to high as the number of shelves increases, in order to conform to the characteristic of hot steam rising to each shelf and to maintain a uniform distribution of moisture in each shelf. Since the hot steam moves upward and rises continuously, it is actually less easy for the hot steam to come into contact with the lower shelves. Therefore, more nozzles can be installed on the lower shelves.
[0018] Preferably, each layer of the pipe assembly is equipped with a hot air component to prevent excessive heat loss of hot steam after it is transported through the pipes. The higher the temperature of the steam, the stronger its activity, which is conducive to the absorption of moisture by the tobacco leaves. The hot air component can also be set according to the length of the frame. If the frame is long, multiple points can be set to ensure that the temperature of the water vapor at each point is similar.
[0019] Preferably, each humidification tube is equipped with a temperature sensor, which is connected to a control component. The control component controls the output of the hot air component based on the feedback from the temperature sensor. The control component can be used to dynamically control the temperature output by the hot air and output the temperature according to actual needs. The control component can be implemented using existing technology.
[0020] Preferably, the nozzle is equipped with an electronically controlled valve, which is connected to the control component. Each humidification tube is equipped with a humidity sensor. The control component controls the number of nozzles that are opened based on the feedback from the humidity sensor. Through the regulation of the control component, precise humidification is achieved, ensuring that the water vapor conditions of the tobacco packs at each location are approximately the same.
[0021] The temperature and humidity sensors can be connected to the control components via wires, but wireless connections, such as Wi-Fi, mobile networks, and Bluetooth, are preferred.
[0022] Preferably, the shed body is foldable so that it can be stored away, reducing the space occupied. The shed body is equipped with a door curtain to increase the airtightness of the shed and reduce the impact of the external environment on the interior space. The bottom of the shed body can also be equipped with casters so that the shed body can be moved.
[0023] Preferably, a water return trough is provided at the lower end of the inner wall of the shed. The water return trough is connected to a dehumidification device through a water pump. Water droplets on the shed flow into the water return trough along the inner wall of the shed, and the water is recycled and reused, saving water resources, preventing water accumulation on the shed floor, and providing a safe environment for tobacco pack transportation.
[0024] Preferably, the diversion component includes a converging part and a guiding part. The converging part is connected to the guiding part, allowing water droplets on the roof to flow into the guiding part along the converging part. The guiding part directs the water droplets toward the side wall of the roof. The converging part is a convex structure extending downward along an arc from the roof. The bottom end of the converging part extends horizontally along an arc to form the guiding part. Both of these components guide the water droplets to the side wall of the roof, preventing water from the roof from falling directly onto the tobacco packs. Furthermore, the water droplets guided to the side wall of the roof can be used in conjunction with the return water tank for water resource recycling.
[0025] The beneficial effects of this utility model are as follows:
[0026] (1) Each shelf is equipped with a humidification pipe. The humidification pipe is set on the shelf according to the characteristics of hot steam to ensure that the tobacco packs are moistened evenly. Humidity sensors and temperature sensors are also set to realize dynamic adjustment of the moistening process.
[0027] (2) A drainage device is provided at the top of the shed to collect water droplets at the top of the shed and flow into the return water trough along the inner wall of the shed, preventing water droplets from dripping directly onto the tobacco packs and causing excessive humidity in the upper tobacco packs, thus ensuring that the upper tobacco packs are evenly moistened.

[0043] like Figure 1-7 As shown, a tobacco pack rehumidification shed includes a shed body 1, a frame 2, a rehumidification device 4, and a pipe assembly 3; the shed body 1 is enclosed and its top is inclined to prevent the external environment from affecting the space inside the shed; the top of the shed body 1 is provided with a drainage component 13 to guide water droplets from the top of the shed body 1 to collect and flow down.
[0044] The frame 2 includes multiple layers of shelves 21 evenly arranged. Each shelf 21 is hollowed out and has cigarette packs evenly placed on it. The cigarette packs are distributed in a single layer on the shelf 21.
[0045] The rehumidification device 4 is connected to the pipe assembly 3. The rehumidification device 4 is used to monitor the ambient humidity and temperature and can spray hot steam to humidify the tobacco leaves.
[0046] The tube assembly 3 includes multiple sets of humidifying tubes 31, which are wound around each layer of the frame 2. The humidifying tubes 31 are equipped with nozzles (not shown in the figure) for spraying hot and humid gas into the tobacco pack.
[0047] Preferably, the bottom of the frame 2 is mesh-like, and each layer of the frame 2 is evenly placed with a layer of smoke packs to prevent the smoke packs from piling up and causing the interior to be unable to humidify or to have a poor humidification effect. The mesh-like bottom of the frame 2 is conducive to the flow of hot steam and increases the humidification effect.
[0048] The rehumidification device 4 includes a control component, a steam injection component, and a hot air component 32, with the control component connected to the evaporation injection component and the hot air component 32.
[0049] Preferably, the humidifying tube 31 is wound from the bottom of the shelf 21 to the top, the distribution area of the humidifying tube 31 at the bottom of the shelf 21 is larger than the distribution area of the humidifying tube 31 at the top of the shelf 21, and the shelf 21 is detachable from the humidifying tube 31.
[0050] Based on the different distributions of frame 2 and pipe group 3, another embodiment is (e.g.) Figure 8As shown): Pipe assembly 3 is located on both sides of frame 2. Humidifying pipe 31 is provided on both sides of each layer of frame 21. As a preferred example, the humidifying pipe 31 is located below the layer of frame 21. Alternatively, humidifying pipe 31 can be provided around each layer of frame 21. The steam sprayed by the humidifying pipe 31 is evenly distributed, which is beneficial to the uniform humidification of tobacco leaves.
[0051] After the jet function of the rehumidification device is turned on, the hot steam humidifies the tobacco leaves layer by layer along the humidification pipe 31 under the heating of the hot air component 32. Since the humidification pipe 31 is evenly distributed in each layer, the water vapor received at each point in each layer is almost the same, so as to ensure that the humidification effect of the tobacco pack is more uniform.
[0052] Preferably, the frame 2 includes a frame 22 and a shelf 21. The frame 22 is provided with a horizontally oriented track, and the shelf 21 is connected to the track and can move along the track.
[0053] Preferably, the frame 22 and the shelf 21 are connected by a drawer, and the shelf 21 slides within the track.
[0054] Preferably, the water vapor ejected from the nozzle is distributed in a fan shape, increasing the jet area and making the water vapor distribution more uniform; the distribution position of the nozzle can be set according to the water vapor received at each position of the tobacco pack to ensure uniform water vapor ejection.
[0055] Preferably, the number of nozzles on the humidification pipe 31 gradually decreases from low to high as the number of layers in the frame 2 increases, in order to conform to the characteristic of hot steam rising to the upper layer 21 and to keep the moisture distribution of each layer 21 uniform. Since the hot steam moves upward and rises continuously, it is actually less easy for the lower layers to come into contact with the hot steam. Therefore, more nozzles can be set in the lower layers.
[0056] Preferably, each layer 21 of the pipe assembly 3 is equipped with a hot air assembly 32 to prevent excessive heat loss of hot steam after it is transported through the pipes. The higher the temperature of the steam, the stronger its activity, which is conducive to the absorption of moisture by the tobacco leaves. The hot air assembly 32 can also be set according to the length of the frame 2. If the length of the frame 2 is too long, multiple points can be set to ensure that the temperature of the water vapor at each point is similar.
[0057] One example is that each shelf 21 can be equipped with two humidification pipes 31 and two hot air assemblies 32, located at opposite ends of the two humidification pipes 31, to ensure that the temperature of the blown water vapor is uniform.
[0058] Another embodiment is as follows: Each humidification tube 31 is equipped with a temperature sensor, which is connected to a control component. The control component controls the output of the hot air component 32 based on the feedback from the temperature sensor. The control component can dynamically control the temperature output by the hot air and output the temperature according to actual needs. The control component can be implemented using existing technology. The nozzle is equipped with an electric control valve, which is connected to the control component. Each humidification tube 31 is equipped with a humidity sensor. The control component controls the number of nozzles that are opened based on the feedback from the humidity sensor. Through the regulation of the control component, precise humidification is achieved, ensuring that the water vapor conditions of the tobacco packs at each location are approximately the same.
[0059] The temperature and humidity sensors can be connected to the control components via wires, but wireless connections, such as Wi-Fi, mobile networks, and Bluetooth, are preferred.
[0060] The temperature and humidity sensors can be connected to the control components via wires, but wireless connection is preferred as it avoids damage in hot and humid environments compared to wired connections.
[0061] If the humidity sensor at the top layer reports excessive humidity, the control component will close some of the upper layer nozzles to balance the humidity. Conversely, if the humidity at the top layer is too low, the number of nozzles that open will increase. If the temperature at the top layer is too high, the control component will also reduce the power of the upper layer hot air component 32. The same applies if the humidity or temperature at other layers is too high or too low.
[0062] Preferably, the shed body 1 is foldable so that it can be stored away, reducing the space occupied. The shed body 1 is equipped with a door curtain 14 to increase the airtightness of the shed and reduce the impact of the external environment on the space inside the shed. The bottom of the shed body 1 can also be equipped with casters so that the shed body 1 can be moved.
[0063] Preferably, a water return trough 11 is provided at the lower end of the inner wall of the shed 1. The water return trough 11 is connected to the dehumidification device 4 through a water pump 12. Water droplets on the shed 1 flow into the water return trough 11 along the inner wall of the shed 1, and the water is recycled and reused, saving water resources, preventing water accumulation on the shed floor, and providing a safe environment for tobacco pack transportation.
[0064] Preferably, the diversion component 13 includes a converging part 131 and a guiding part 132. The converging part 131 is connected to the guiding part 132, so that water droplets on the roof flow into the guiding part 132 along the converging part 131. The guiding part 132 guides the water droplets to the side wall of the roof body 1. The converging part 131 is a convex structure that extends downward along an arc from the roof. The bottom end of the converging part 131 extends horizontally along an arc to form the guiding part 132. The two components guide the water droplets to the side wall of the roof body 1, preventing water from the top of the roof body 1 from falling directly onto the tobacco packs. Furthermore, the water droplets guided to the side wall of the roof body 1 can also be used in conjunction with the return water tank 11 for water resource recycling.
[0065] Water droplets flow down the side wall of the shed 1 and collect in the return water tank 11. The return water tank 11 is inclined so that the water in the final return water tank 11 converges to a point. A water pump 12 is installed at the convergence point, and the water pump 12 sends the water into the water tank of the dehumidification device 4.
[0066] An example: The three sides of the shed body 1 other than the side where the door curtain 14 is located are provided with water return channels 11, namely the first water return channel 111, the second water return channel 112, and the third water return channel 113; the first water return channel 111 is inclined towards the third water return channel 113, the second water return channel 112 is also inclined towards the third water return channel 113, the two ends of the third water return channel 113 are inclined towards the midpoint, and a water pump 12 is provided in the middle of the third water return channel 113, and the water pump 12 sends water into the moisture return device 4.
