Description

Technical Field

[0001] This utility model relates to the technical field of cigar tobacco products, specifically to a device for controlling environmental parameters during the fermentation period of cigar tobacco. Background Technology

[0002] In recent years, the domestic cigar market has experienced rapid growth, with the introduction of Chinese-style cigar flavors that better suit Chinese tastes, gradually gaining popularity among domestic cigar smokers. However, foreign cigars still dominate the high-end market. Compared to high-quality tobacco leaves from foreign producing regions, domestically produced cigar tobacco leaves still lag significantly in terms of aftertaste comfort and aroma. While my country's cigar tobacco leaf production has increased year after year, high-quality cigar tobacco leaves remain scarce. Fermentation technology is a crucial step in shaping the quality of cigar tobacco leaves, softening the smoke and enhancing the aroma, darkening the color of the leaves, reducing their density and water retention, and improving combustibility. Microorganisms play a vital role in fermentation; as they grow and multiply, various macromolecules in the cigar tobacco leaves are decomposed, driving the fermentation process. The fermentation process involves steps such as grading, rehydration, stacking, turning, and re-stacking. Different fermentation stages require different levels of microbial decomposition and transformation capabilities; a suitable microbial growth environment is beneficial for controlling the degree of fermentation and improving the quality of the fermented tobacco leaves.

[0003] A prior art patent with publication number CN221980044U discloses a solution including a fermentation chamber. The fermentation chamber has an exhaust fan on its top, and contains several dehumidifying heat pumps and several fermentation racks. The dehumidifying heat pumps are used to control the temperature and humidity of the fermentation chamber, and the fermentation racks are used to hang tobacco leaves and adjust the gaps between the tobacco leaves. The temperature and humidity in the cigar fermentation chamber are regulated by the dehumidifying heat pumps, and the airflow is created by the exhaust fan, which is beneficial to promoting the fermentation of tobacco leaves. The fermentation racks are used to hang tobacco leaves and adjust the gaps between the tobacco leaves to make the fermentation of tobacco leaves more uniform. This solves the problems of inaccurate temperature and humidity control in current tobacco fermentation, which leads to poor fermentation results, and the inability to adjust the gaps between tobacco leaves, which leads to poor fermentation uniformity.

[0004] As existing devices are used, the shortcomings of this technology have gradually become apparent, mainly in the following aspects:

[0005] Currently, in practical production, most production areas adopt the fermentation method of manual periodic turning of stacks. The fermentation environment is mostly constant temperature and humidity or natural conditions throughout the fermentation period, which makes it difficult to control the uniformity of tobacco leaf fermentation and to achieve suitable fermentation environment conditions at different fermentation stages.

[0006] As can be seen from the above, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0058] The innovation of this device lies in the innovative positional relationship between the various structures. The specific structure and electrical connection method of each structure are well known to those skilled in the art and are not the innovation of this invention, so they will not be described in detail here.

[0059] The working principle of this device is as follows:

[0060] 1. Sample feeding operation of cigar tobacco leaf screening and fermentation device

[0061] After drying, the cigar tobacco leaves are initially selected, choosing leaves of the same variety from the middle or upper parts of the leaves. Leaves with large areas of damage, mold, disease spots, or infectious pathogens are removed. The remaining leaves are bundled into bundles of 25-30 leaves each. After bundling, each bundle is labeled according to the experimental fermentation requirements, and the bundle number is recorded. All bundles are weighed and counted, and every 200 bundles of tobacco leaves are set up as a fermentation stack, with the number of stacks determined based on the total number of bundles. The bundles are placed in sample feeding area 1, with 100 bundles of tobacco leaves placed in each slot 11 of the sample feeding area. Different fermentation racks are set up on control panel 6 for each slot 11 of the sample feeding area. The main pipe rack 52 is connected to the water and air pipes, and the water pump and ventilation pipes are turned on.

[0062] 2. Setting environmental parameters during the fermentation period of cigar tobacco leaves

[0063] Set the fermentation period to 60 days on console 6 and set the following control conditions: 1. Set the temperature and humidity at the center of the tobacco stack as a curve with the fermentation period. Set the temperature and humidity to 30℃ and 60% for days 0-15 after fermentation, 40℃ and 70% for days 15-45, and 30℃ and 60% for days 45-60; 2. Set the turning of the tobacco stack to fixed time. Set the turning to days 8, 15, 23, 30, 38, 45, and 53 after fermentation. Set the tobacco stacks to be evenly rotated each time they are turned, and each tobacco stack is dismantled and re-stacked; 3. Set the gas exchange value of the tobacco stacks to be changed according to the concentration of oxygen and unpleasant odor gases. Set the oxygen concentration range to 5%-20%, and set the air exchange to dilute the sulfur dioxide, ammonia, hydrogen sulfide and other gases when the concentration is greater than 1%; 4. Do not introduce specific fermentation strains.

[0064] 3. Stacking of cigar tobacco leaves before fermentation

[0065] The control console 6 is activated. The movable gripper 16, in coordination with the movable gripper extension rod 15, the movable gripper joint 14, and the movable gripper rotating base 13, reciprocates along the movable gripper track 12, transporting cigarette butts from every two sample loading area slots 11 to the conveyor belt 21 in sequence. The infrared sensor 22 records the movement trajectory and number of cigarette butts at the top of the conveyor belt 21. When a cigarette butt enters the range of motion of the multi-joint robotic arm 23, the multi-joint robotic arm 23 moves the cigarette butt to the fermentation rack placement platform 24. A fermentation rack is pre-placed on the fermentation rack placement platform 24, and the multi-joint robotic arm 23 secures the cigarette butt to the fermentation support frame 45. The control console 6 determines the stacking status of the tobacco piles based on the tobacco bundle count on the infrared sensor 22. Once the tobacco piles are stacked, the telescopic forklift arm 34 inserts into the fermentation rack moving support 48, lifts the tobacco pile along the forklift body 33, and moves it along the forklift moving track 31 to the node corresponding to the tobacco pile on the fermentation rack moving track 42. The tobacco pile is then placed on the node, and the fermentation rack chassis 44 is magnetically connected to the node. The control console 6 receives the wiring connection information and continues stacking the next tobacco pile. After all tobacco piles are stacked, the control console 6 controls the corresponding lifting connection device 53 to descend, rotating and connecting the water and gas pipe 54 to the water and gas channel connection plate 47.

[0066] 4. Environmental parameter control during the cigar stack fermentation period

[0067] Control console 6 adjusts the water-air pipeline, parameter control module 49, and gas exchange pipeline 410, introducing 30°C air for temperature control, and shuts it off once the set temperature is reached. Gas detector 43, temperature and humidity sensor 411, and tobacco leaf color sensor 412 are activated, and gas detector 43 and tobacco leaf color sensor 412 rise along the track. Based on changes in temperature, humidity, and gas composition during tobacco stack fermentation, control console 6 selectively activates the water-air flow function. On the 15th and 45th days of fermentation, the tobacco fermentation environmental parameters are changed according to preset parameters.

[0068] 5. Turning over and repacking cigar stacks

[0069] After the predetermined number of days for turning the stack is reached, the fermentation rack chassis 44 is disconnected from the node, and the water and air pipe 54 is rotated and disconnected from the water and air channel connecting plate 47. The control console 6 controls the telescopic forklift arm 34 to insert one of the fermentation rack moving supports 48, moving the tobacco stack to the fermentation rack placement platform 24. The multi-joint robotic arm 23 removes the tobacco bundles and transports them back to the tobacco leaf sampling area via the conveyor belt 21. The moving gripper 16 moves the tobacco bundles from the upper, middle, and lower parts of the original fermentation stack to different sampling area placement grids 11, and after adjusting the order of the parts, sends them back to the conveyor belt 21, thus changing the position of the tobacco leaves in each part of the stack. After this, the stack is re-stacked. After stacking is completed, the stack returns to the stack fermentation area 4 via the stack moving area 3 to continue the turning of the next stack. During this process, the stacking position of each stack is adjusted, with the stacks originally at the edge being moved to the center, and the original stack orientation is changed via the forklift rotating base 32. After all the tobacco stacks are placed, the fermentation rack base 44 is attached to the node, and the water and gas pipe 54 is rotated and connected to the water and gas channel connecting plate 47.

[0070] 6. Removal and data processing of cigar stacks after fermentation.

[0071] After fermentation is completed on day 60, the fermentation rack base 44 is disconnected from the node, the water-air pipe 54 is rotated and disconnected from the water-air channel connection plate 47, and the main pipe rack 52 is disconnected from the water-air pipe. The control console 6 controls the telescopic forklift arm 34 to insert one of the fermentation rack moving supports 48, moving the tobacco stack to the fermentation rack placement platform 24. The multi-joint robotic arm 23 removes the tobacco bundles and transports them back to the tobacco sample feeding area via the conveyor belt 21. The moving gripper 16 then transports each tobacco bundle back to its corresponding sample feeding area placement grid 11. The control console displays a map showing the positional changes of each tobacco stack during this fermentation period, daily temperature and humidity, gas composition, and tobacco leaf color changes in each stack, as well as records of tobacco leaf position adjustments during each stack turning.
