Description

Technical Field

[0001] The invention relates to the technical field of tobacco leaf baking, and in particular to a partitioned dense baking room with variable tobacco loading density. Background Art

[0002] Tobacco leaf baking is a key link in tobacco production. The baking quality of tobacco leaves is directly related to the flavor and grade of cigarettes. The intensive tobacco leaf baking room is the carrier of tobacco leaf baking technology, which is very important to ensure the baking quality of tobacco leaves. my country's intensive tobacco leaf baking room has two forms: rising airflow and falling airflow. The intensive tobacco leaf baking room includes a loading room and a heating room, which are separated by a heat insulation wall. Air inlets and return air outlets are respectively opened on the heat insulation wall to connect the loading room and the heating room. The fan is used to force hot air circulation in the baking room, and the dry and cold air in the environment is sucked into the heating room, and sent to the loading room after heating, and the water vapor evaporated from the tobacco leaves is brought to the external environment. The fresh tobacco leaves hung on the hanging rack lose water and turn yellow in the circulating hot air environment, and the baking of the tobacco leaves is completed in this cycle. However, under the structure of the existing intensive baking room, the temperature of the tobacco leaves baking in the loading room is vertical. In the vertical direction, there is a phenomenon of decreasing gradient from the air inlet to the return air outlet and from the farthest to the nearest distance to the insulation wall in the horizontal direction. Due to the uneven temperature field, the yellowing degree of the overall tobacco leaves will be asynchronous and the water loss state will be inconsistent during baking. During the baking process, the tobacco leaves in the high-temperature zone will wither and collapse first, resulting in the wind speed between the withered and collapsed tobacco leaves being greater than the wind speed between the non-withered and collapsed tobacco leaves in the low-temperature zone. Under the dual effects of different temperatures and different wind speeds, the degree of inconsistent yellowing and water loss of the tobacco leaves is aggravated, causing the tobacco leaves in the high-temperature zone to be over-baked and the tobacco leaves in the low-temperature zone to be incompletely baked, thereby reducing the overall baking quality of the tobacco leaves. At the same time, when the existing baking room bakes the tobacco leaves, in order to make the entire tobacco leaves turn yellow, the tobacco leaves that have been baked and turned yellow need to wait for the green tobacco leaves to turn yellow, further extending the total baking time of the tobacco leaves, increasing the energy consumption of tobacco baking, and making it inconvenient to use. Summary of the invention

[0003] In view of the defects and problems existing in the above-mentioned defects and problems, the present invention provides a partitioned intensive curing room with variable tobacco loading density, which has a unique structure and is easy to use. The tobacco loading room is divided into different areas according to the temperature gradient, and the tobacco rods on which tobacco leaves are hung can be adjusted by a tobacco rod adjustment unit. By utilizing the pitch difference between multiple spiral sheets on the shaft rod, multiple tobacco rods can be made to be dense or sparse on the shaft rod. Operators can flexibly adjust the density of the tobacco rods according to the curing capacity of each area. The tobacco leaf hanging density is increased in the high-temperature zone to reduce the air flow rate and temperature between the leaves, and the tobacco leaf hanging density is reduced in the low-temperature zone to increase the air flow rate and temperature between the leaves, thereby achieving relatively uniform temperature in each area of ​​the tobacco loading room, keeping the dehydration speed and yellowing degree of the overall tobacco leaves in the tobacco loading room relatively consistent, thereby improving the quality of tobacco leaf baking, reducing the total time of tobacco leaf baking, and saving energy consumption for tobacco baking.

DETAILED DESCRIPTION

[0027] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0028] Example 1: When tobacco leaves are baked in an existing intensive drying room, the temperature of the tobacco leaves in the tobacco loading room decreases gradually from the air inlet to the air return outlet in the vertical direction and from the insulation wall in the horizontal direction. Due to the uneven temperature field, the yellowing degree of the overall tobacco leaves will be asynchronous during baking, and the water loss state will be inconsistent. During the baking process, the tobacco leaves in the high-temperature zone will wither and collapse first, resulting in the wind speed between the withered and collapsed tobacco leaves being greater than the wind speed between the non-withered and collapsed tobacco leaves in the low-temperature zone. Under the dual effects of different temperatures and different wind speeds, the degree of inconsistent yellowing and water loss of the tobacco leaves is aggravated, causing the tobacco leaves in the high-temperature zone to be over-baked and the tobacco leaves in the low-temperature zone to be incompletely baked, thereby reducing the overall baking quality of the tobacco leaves.

[0029] In view of the above problems, this embodiment provides a partitioned dense baking room with variable smoke density, such as Figure 1-3As shown, it includes a baking room, which is provided with a smoke loading chamber 1 and a heating chamber 4, a partition plate 8 is arranged between the smoke loading chamber 1 and the heating chamber 4, an air inlet 9 is opened through the top of the partition plate 8, and a return air port 10 is opened through the bottom of the partition plate 8, the heating chamber 4 and the smoke loading chamber 1 are connected through the air inlet 9 and the return air port 10, and a dehumidification window 11 is opened on the outer side of the bottom of the heating chamber 4, and a fresh air valve is arranged on the side of the heating chamber 4, and the baking room can dehumidify the interior through the dehumidification window 11, an axial flow fan 5 is arranged in the heating chamber 4, a fan frame is arranged below the axial flow fan 5, the axial flow fan 5 is fixedly installed on the fan frame, and the fan frame is fixedly connected to the inner wall of the heating chamber 4, and the axial flow fan 5 can suck the outside air into the heating chamber 4 through the fresh air valve after starting, a condenser 6 is arranged below the axial flow fan 5, and an air source heat pump is arranged outside the heating chamber 4 12. The output end of the air source heat pump 12 is connected to the input end of the condenser 6. Through the cooperation between the air source heat pump 12 and the condenser 6, the airflow entering the heating chamber 4 can be heated to form hot air. An auxiliary heating element 7 is arranged under the condenser 6. The auxiliary heating element 7 is an electric heating wire or a heating tube. The airflow can be auxiliary heated by the auxiliary heating element 7. The air source heat pump 12 enables the condenser 6 to release high-temperature heat in the heating chamber 4. The refrigerant completes the gaseous pressure and temperature increase process in the air source heat pump 12, releases high-temperature heat after entering the condenser 6, and is cooled and converted into a liquid state. After circulating to the air source heat pump 12, the liquid absorbs heat and evaporates and is converted into a gaseous state again. At the same time, the temperature can drop to -20℃~-30℃. The air around the air source heat pump transfers heat to the refrigerant, and the refrigerant is then transported to the condenser 6 for circulation.

[0030] A plurality of cigarette hanging racks 301 are evenly arranged in the cigarette loading chamber 1, and the plurality of cigarette hanging racks 301 evenly divide the cigarette loading chamber 1 into three equal parts, and the cigarette hanging racks 301 are arranged up and down to divide the cigarette loading chamber 1 into three layers, and each cigarette hanging rack corresponds to each area divided by temperature; a fixing seat 302 is fixed on the top of the cigarette hanging rack 301, and the upper and lower adjacent cigarette hanging racks 301 are fixedly connected by the fixing seat 302, and a first shaft seat 304 and a second shaft seat 305 are symmetrically arranged on the inner side of the cigarette hanging rack 301, and the first shaft seat 304 corresponds to the second shaft seat 305, and a shaft rod 306 is rotatably mounted between the first shaft seat 304 and the second shaft seat 305, and the left end of the shaft rod 306 extends A first shaft seat 304 is extended out, and a driving motor 303 is fixedly installed on the left side of the cigarette hanging rack 301. The output end of the driving motor 303 is connected to the shaft rod 306 extending out of the first shaft seat 304. After the driving motor 303 is started, the shaft rod 306 can rotate in the first shaft seat 304 and the second shaft seat 305. A plurality of spiral pieces 307 are arranged on the shaft rod 306 in sequence from left to right. The spiral rings of the spiral pieces 307 are the same. An isolation plate 308 is arranged between adjacent spiral pieces 307. The isolation plate 308 is fixedly sleeved on the shaft rod 306. The difference between the pitch of each spiral piece and the pitch of the adjacent spiral piece in the previous section is ∆2cm. Figure 3 As shown, the length D2 of the second spiral sheet on the shaft 306 is greater than the length D1 of the first spiral sheet, and the pitch of the second spiral sheet increases by ∆2 cm compared to the pitch of the first spiral sheet. The calculation formula for each spiral sheet 307 is D1=D1, D2=D1+∆2, D3=D1+2∆2, D4=D1+3∆2....D n =D1+(n-1)∆2, the pitch of each spiral piece is increased by ∆2cm compared with the pitch of the previous adjacent spiral piece, so that the spiral piece 307 on the shaft 306 is in a state from tight to loose, and the multiple spiral pieces and the isolation plate 308 on the shaft 306 are prefabricated; Figure 8-9 As shown, the smoke loading chamber is divided into five temperature zones from high to low according to the temperature in the smoke loading chamber, namely zone A, zone B, zone C, zone D and zone E. The smoke loading density of each zone decreases successively, among which the temperature in zone A is the highest, the temperature in zone E is the lowest, the temperature in zone B is lower than that in zone A, the temperature in zone C is lower than that in zone B, and the temperature in zone D is lower than that in zone C, that is, the smoke loading density in zone A is the densest state, and the smoke loading density in zone E is the loosest state, and each smoke hanging rack 301 corresponds to each temperature zone.

[0031] When the tobacco leaves are being roasted, the door 2 is opened, and the operator hangs the tobacco leaves on the braided tobacco rod 15, and sequentially places the braided tobacco rod 15 in each spiral piece 307 on the shaft 306. After the braided tobacco rod 15 is hung, the operator controls the drive motor 303 in each temperature zone of the tobacco loading chamber 1 to start, so that the drive motor 303 is reversed to drive the shaft 306 to rotate, and the shaft 306 rotates to drive the spiral piece 307, and the spiral piece 307 pushes the braided tobacco rod 15 to the left, and the braided tobacco rod 15 in the spiral piece 307 is pushed to the left. When the maximum stroke is reached, it will be limited by the isolation plate 308 and will no longer move. Since the difference between the pitch of each spiral sheet and the pitch of the adjacent spiral sheet in the previous section is ∆2cm, when the braided cigarette rods in the current spiral sheet are rotated to the maximum stroke, the braided cigarette rods in the previous spiral sheet are limited by the isolation plate and rotate in place. At this time, the braided cigarette rods in the adjacent subsequent spiral sheet are still in a rotated state until they are rotated to the maximum stroke. When all the braided cigarette rods are rotated to the maximum stroke, the density of hanging cigarettes on the cigarette rack is in the densest state.

[0032] The smoke loading density is adjusted according to the baking temperature of zones A, B, C, D and E, so that the smoke loading density in zone A is the densest, the smoke loading density in zone B is smaller than that in zone A, the smoke loading density in zone C is smaller than that in zone B, the smoke loading density in zone D is smaller than that in zone D, and the smoke loading density in zone E is smaller than that in zone D, so that the smoke loading density in zones A to E decreases successively.

[0033] The density of smoke in area A has been adjusted to the tightest state. When adjusting the density of smoke in area B, the operator controls the driving motor of area B to rotate forward, and the shaft drives the spiral piece, so that the spiral piece pushes the cigarette rod to the right. Since the difference between the pitch of each spiral piece and the pitch of the adjacent spiral piece in the previous section is ∆2cm, the distance between the cigarette rods in adjacent spiral pieces will gradually increase. The operator adjusts the cigarette rod to the optimal baking density of area B, so that the density of smoke in area B is less than that in area A. When adjusting the density of smoke in area C, the operator controls the cigarette rod in area C to rotate forward. The driving motor rotates forward, causing the spiral slices to push the cigarette rods to the right, and the distance between the cigarette rods in adjacent spiral slices will gradually increase. The operator adjusts the cigarette rods to the optimal baking and smoking density in zone C, so that the smoking density in zone C is less than that in zone B. When adjusting the smoking density in zone D, the operator controls the driving motor in zone D to rotate forward, causing the spiral slices to push the cigarette rods to the right, and the distance between the cigarette rods in adjacent spiral slices will gradually increase. The operator adjusts the cigarette rods to the optimal baking and smoking density in zone D, so that the smoking density in zone D is less than that in zone C.

[0034] When adjusting the cigarette density of zone E, the operator controls the driving motor of zone E to rotate forward, so that the spiral slice pushes the cigarette rod to the right, and the distance between the cigarette rods in adjacent spiral slices gradually increases until the cigarette rods in the spiral slices are pushed to the maximum stroke. When the cigarette rods in the spiral slices are pushed to the maximum stroke, they will be limited by the isolation plate and will no longer move. Since the difference between the pitch of each spiral slice and the pitch of the adjacent spiral slice in the previous section is ∆2cm, when the cigarette rods in the current spiral slice are pushed to the maximum stroke, the cigarette rods in the previous spiral slice are limited by the isolation plate and rotate in place. At this time, the cigarette rods in the adjacent subsequent spiral slices are still in the pushed state until they are pushed to the maximum stroke. Stroke, when all the braided tobacco rods are rotated and pushed to the maximum stroke, the hanging density of the tobacco on the hanging rack is adjusted to the loosest state, so that the tobacco loading density in area E is in the loosest state; the operating personnel flexibly adjust the density of the braided tobacco rods according to the baking temperature of each area, increase the hanging density of tobacco leaves in the high temperature area to reduce the air flow rate and temperature between the tobacco leaves, and reduce the hanging density of tobacco leaves in the low temperature area to increase the air flow rate and temperature between the tobacco leaves, so as to achieve relatively uniform temperature in each area of ​​the tobacco loading room, so that the dehydration speed and yellowing degree of the overall tobacco leaves in the tobacco loading room remain relatively consistent, thereby improving the quality of tobacco leaf baking, shortening the time for yellow tobacco leaves to wait for green tobacco leaves to turn yellow, and reducing the total baking time of tobacco leaves.

[0035] Example 2, a partitioned dense baking room with variable smoke density in this embodiment is described centering on the differences from Example 1.

[0036] In this embodiment, Figure 5As shown, the multi-segment spiral pieces 307 on the shaft 306 are symmetrically arranged, and the spiral directions of the spiral pieces 307 are opposite. The symmetrically arranged spiral pieces 307 use the center of the shaft 306 as the dividing line. The multi-segment spiral pieces 307 are sequentially outward from the center of the shaft 306. The difference between the pitch of each segment of spiral pieces and the pitch of the previous segment of adjacent spiral pieces is ∆2. The multi-segment spiral pieces 307 are in a state from tight to loose. The operator places a plurality of braided cigarette rods 15 in each spiral piece. When the driving motor starts to reverse, the shaft drives the spiral piece, and the spiral piece rotates and pushes the braided cigarette rod toward the center of the shaft, so that the braided cigarette rod moves from the outside to the inside. When the braided cigarette rods 15 in the spiral sheet 307 are rotated to the maximum stroke, they are limited by the isolation plate 308 and no longer move. Since the difference between the pitch of each spiral sheet and the pitch of the adjacent spiral sheet in the previous section is ∆2cm, when the braided cigarette rods in the current spiral sheet are rotated to the maximum stroke, the braided cigarette rods in the previous spiral sheet are limited by the isolation plate and rotate in place. At this time, the braided cigarette rods in the adjacent subsequent spiral sheet are still in the state of being rotated until they are rotated to the maximum stroke. When all the braided cigarette rods are rotated to the maximum stroke, the density of hanging cigarettes on the cigarette hanging rack is in the densest state.

[0037] When the driving motor starts to rotate forward, the spiral slices push the cigarette rods toward both ends of the shaft rod, so that the cigarette rods move from the inside to the outside, and the distance between the cigarette rods in adjacent spiral slices gradually increases until the cigarette rods in the spiral slices are pushed to the maximum stroke. When the cigarette rods in the spiral slices are pushed to the maximum stroke, they will be limited by the isolation plate and will no longer move. Since the difference between the pitch of each spiral slice and the pitch of the adjacent spiral slice in the previous section is ∆2cm, after the cigarette rods in the current spiral slice are pushed to the maximum stroke, the cigarette rods in the previous spiral slice are limited by the isolation plate and rotate in place. At this time, the cigarette rods in the adjacent subsequent spiral slices are still in a pushed state until they are pushed to the maximum stroke. When all the cigarette rods are pushed to the maximum stroke, the cigarette hanging density on the cigarette hanging rack is adjusted to the loosest state; the operator can flexibly adjust the cigarette rods according to different cigarette loading densities and adjust the cigarette rods to the appropriate position, so that the density of multiple cigarette rods on the cigarette hanging rack can be flexibly adjusted.

[0038] Example 3, a partitioned dense baking room with variable smoke density in this embodiment is described centering on the differences from Example 1.

[0039] In this embodiment, Figure 6As shown, a temperature sensing assembly is arranged on the shaft 306, and the temperature sensing assembly includes a hook 13, and the hook 13 is hung on the isolation plate at the center of the shaft 306. A temperature sensor 14 is arranged at the bottom of the hook 13. When the tobacco leaves are roasted, the temperature in each temperature zone can be monitored in real time through the temperature sensor 14. When the temperature in a certain zone increases, the temperature sensor 14 sends a signal to the external controller, and the external controller starts the driving motor in the zone, and the driving motor reverses to drive the shaft, and the spiral piece 307 pushes the braided tobacco rod 15 to the left, shortening the distance between the braided tobacco rods 15 in adjacent spiral pieces, thereby improving the temperature. High tobacco leaf hanging density reduces the air flow rate and temperature between leaves; when the temperature in a certain area decreases, the temperature sensor 14 sends a signal to the external controller, and the external controller starts the drive motor in the area. The drive motor rotates forward to drive the shaft rod, and the spiral sheet 307 pushes the braided tobacco rod 15 to the right, increasing the distance between the braided tobacco rods 15 in adjacent spiral sheets, reducing the tobacco leaf hanging density, and increasing the air flow rate and temperature between leaves, thereby ensuring that the tobacco leaves in the entire tobacco baking process in the loading chamber 1 turn yellow and lose water synchronously and the baking quality is uniform, and the tobacco leaf hanging density is automatically adjusted, saving time and effort and improving the tobacco leaf baking efficiency.

[0040] Example 4, a partitioned dense curing barn with variable smoke density in this embodiment is described centering on the differences from Example 1.

[0041] In this embodiment, an arc-shaped guide plate 16 is provided above the fan 5 in the heating chamber. The arc-shaped guide plate 16 is fixedly connected to the inner top of the heating chamber 4. The arc-shaped guide plate 16 can guide the airflow blown out by the fan 5, so that the airflow can better enter the smoke loading chamber 1 through the air inlet 9, thereby improving the use efficiency of the fan 5.

[0042] Example 5, a partitioned dense baking room with variable smoke density in this embodiment is described centering on the differences from Example 1.

[0043] In this embodiment, Figure 10-11As shown, the spiral piece 307 is arranged on the fixed sleeve 17, the fixed sleeve 17 is connected with the shaft 306, the spiral rings of the spiral piece 307 are the same, and a separation plate 308 is arranged between adjacent fixed sleeves 17, and the separation plate 308 is connected with the shaft 306. The difference between the pitch of the spiral piece on each section of the fixed sleeve 17 and the pitch of the adjacent spiral piece in the previous section is ∆2cm. The operator sequentially fixes the fixed sleeve 17 on the shaft 306 according to the pitch of each section of the spiral piece, so that the pitches of adjacent spiral pieces are in an increasing or decreasing relationship in sequence; When it is necessary to make the pitch of the spiral piece 307 on the shaft rod 306 change from tight to loose from left to right, first fix the spiral piece with the largest pitch on the shaft rod 306 through the fixed sleeve 17, and then fix the pitches of adjacent spiral pieces on the shaft rod 306 in a decreasing relationship through the fixed sleeves 17 in sequence, and the isolation plate 308 between adjacent fixed sleeves 17 is fixed on the shaft rod; when it is necessary to make the pitch of the spiral piece 307 on the shaft rod 306 change from loose to tight from left to right, first fix the spiral piece with the smallest pitch on the shaft rod 306 through the fixed sleeve, and then fix the pitches of adjacent spiral pieces on the shaft rod 306 in an increasing relationship through the fixed sleeves in sequence, and the isolation plate 308 between adjacent fixed sleeves is fixed on the shaft rod, and the operator can also flexibly combine the spiral pieces 307 according to needs, and fix the spiral pieces 307 on the shaft rod 306 through the fixed sleeves 17, which is flexible to use.

[0044] Example 6, a partitioned dense baking room with variable smoke density in this embodiment is described centering on the differences from Example 1.

[0045] In this embodiment, Figure 12-13As shown, a plurality of rotary push units are sequentially arranged on the shaft, and the rotary push unit includes two symmetrically arranged spiral pieces 307, the spiral directions of the spiral pieces 307 are opposite, and the pitches of adjacent spiral pieces 307 are the same, and a partition plate 308 is arranged between adjacent spiral pieces 307, and the partition plate 308 is fixedly mounted on the shaft 307, and the spiral piece 307 is fixedly connected to the shaft 307 through a fixed sleeve 17, and the rotary push unit A1=rotary push unit A2, and the adjacent rotary push units have the same structure; the operator hangs the tobacco rods in the symmetrically arranged spiral pieces 307 respectively, and controls The control driving motor 303 starts to rotate forward and drives the shaft 306 to rotate forward. Under the action of the spiral blade 307 in the opposite direction of the spiral, the braided cigarette rod 15 in the spiral blade 307 is rotated from outside to inside until the braided cigarette rod in the spiral blade is rotated to the maximum stroke. When the braided cigarette rod in the spiral blade is rotated to the maximum stroke, it will be limited by the isolation plate and will no longer move. At this time, the distance between adjacent braided cigarette rods in the rotary push unit is the closest state. The driving motor 303 is reversed again, and the driving shaft 306 is reversed. Under the action of the opposite direction of the spiral 307, the braided tobacco rod 15 in the spiral sheet 307 is pushed from the inside to the outside until the braided tobacco rod in the spiral sheet is pushed to the maximum stroke. When the braided tobacco rod in the spiral sheet is pushed to the maximum stroke, it will be limited by the isolation plate. At this time, the distance between adjacent braided tobacco rods in the rotary push unit is in the loosest state. By driving the forward and reverse rotation of the motor 303, the braided tobacco rods in the rotary push unit can be made to move back and forth, approaching and moving away from each other, so that the braided tobacco rods are always in a continuous motion state, and the tobacco leaf hanging density is continuously changed, so that the adjacent tobacco leaf hanging density is changed from tight to loose, and then from loose to tight. It is flexible to use. After the driving motor 303 is pre-set with the forward and reverse rotation numbers, it is no longer necessary to manually control the driving motor, which saves time and effort, and keeps the dehydration speed and yellowing degree of the overall tobacco leaves in the tobacco loading room relatively consistent, thereby improving the quality of tobacco leaf baking, reducing the phenomenon of tobacco leaf browning and green tobacco and other bad tobacco, reducing the total time of tobacco leaf baking, and improving the tobacco leaf baking efficiency.

[0046] The above description is only a preferred embodiment of the present invention and does not limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
