Description

[0002] Cigar fermentation can bring unique cigar flavor and aroma to tobacco, and make the color of tobacco uniform. The moisture content of just dried cigar leaf is only 18%~20%, which cannot meet the requirements of fermentation on tobacco moisture, and certain measures need to be taken to increase the moisture content of tobacco. Therefore, it is particularly important to select corresponding and efficient humidification and moisture regain process for different types (cigar cover, cigar core), different leaf positions and different volumes of cigar leaf in production.

[0003] Currently, the moisture regain of cigar core tobacco is mostly carried out by artificial spraying humidification. The tobacco is placed downward on a plastic film cloth, and filtered water or pure water is sprayed on the tobacco by a sprayer. The humidified tobacco is transferred to a moisture balance room (equipped with a humidifier to increase the room air humidity) for loose stacking for more than 12 hours, so that the water droplets on the surface of the tobacco are absorbed, and the moisture circulation between the leaves is promoted to achieve balance. The artificial humidification method is not affected by the external environment and is easy to operate, but the spraying is uneven, the outer tobacco of the tobacco stick is easy to condense clear water, and the inner tobacco is not wet. The moisture content uniformity of the tobacco after moisture regain is poor, and the cycle time is long.

DETAILED DESCRIPTION

[0034] The application will be further described below with reference to the drawings. The following examples are only used to more clearly illustrate the technical solutions of the application, and cannot be used to limit the protection scope of the application.

In addition, the terms "first", "second" and the like are only for description purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined with "first", "second" and the like can explicitly or implicitly include one or more of the features. In the description of the present application, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0036] In the description of the present application, it needs to be understood that, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood through specific circumstances.

[0037] Example one:

[0038] As Figures 1-3 The present application provides a cigar leaf humidifying device, which comprises a box, a lifting assembly arranged in the box, a plurality of clamping jaw assemblies 19 for clamping cigar leaves arranged on the lifting assembly, a same dipping assembly arranged below the clamping jaw assemblies 19 on the inner wall bottom of the box, a spraying assembly arranged in the box, one end of the spraying assembly extending to the outside of the box and being in communication with a spraying water tank 29, and a constant temperature and humidity system arranged in the box.

[0039] Specifically, when the cigar leaf needs to be humidified, the clamping jaw assemblies 19 are used to clamp the cigar leaf, and the size of the clamping jaw assemblies 19 can be adjusted to clamp cigar leaves of different sizes. Then, the cigar leaf is humidified through the cooperation of the lifting assembly, the dipping assembly, the spraying assembly and the constant temperature and humidity system, which ensures the stability of the device during operation, accurately controls the humidification amount, temperature and humidity and other parameters, and ensures the practicability of the device.

[0040] In one embodiment, the lifting assembly comprises a sliding table support frame 10 arranged in the box, symmetrical sliding rails 5 arranged on the sliding table support frame 10, a sliding table 8 slidingly connected to the outer wall of the sliding rails 5 and a driving motor for driving the sliding table 8 to lift, a first limit switch 4, a second limit switch 11 and a zero control switch 6 arranged on the outer wall of one of the sliding rails 5, a turnover cylinder 9 arranged on the outer wall of one of the sliding tables 8, a bearing seat 21 arranged on the outer wall of the other sliding table 8, a rotating shaft 20 rotatably connected between the bearing seat 21 and the turnover cylinder 9, and a plurality of clamping jaw assemblies 19 evenly arranged on the outer wall of the rotating shaft 20.

[0041] Specifically, the lifting assembly is used to adjust the height of the cigar leaf. During operation, the driving motor drives the sliding table 8 to lift, the turnover cylinder 9 and the bearing seat 21 move with the sliding table 8, thereby driving the rotating shaft 20 to lift, and the plurality of clamping jaw assemblies 19 move with the rotating shaft 20, thereby driving the cigar leaf to move up and down. According to actual working needs, the turnover cylinder 9 can drive the rotating shaft 20 to rotate, thereby driving the clamping jaw assemblies 19 to rotate, so as to drive the cigar leaf to move, thereby realizing the standing and upside-down work (turnover work) of the cigar leaf, so as to adapt to different working needs and ensure the practicability of the device. When the driving motor drives the sliding table 8 to move up and down, when the sliding table 8 rises to the first limit switch 4 or falls to the second limit switch 11, the movement of the sliding table 8 is stopped or moved in the opposite direction according to the control program. The zero control switch 6 is used to adjust the zero positioning of the sliding table 8. By adjusting the height of the sliding table 8, the height of the cigar leaf is adjusted.

[0042] In one embodiment, the soaking assembly includes a soaking water tank 18 disposed in the box body, an inlet pipe on the outer wall of the soaking water tank 18, a first solenoid valve 13 at one end of the inlet pipe, a water level detection switch 12 inside the soaking water tank 18, an outlet pipe at the bottom of the soaking water tank 18, and a valve 16 at one end of the outlet pipe.

[0043] like Figure 1 As shown, specifically, the soaking water tank 18 is filled with distilled water for wetting and humidifying the cigar tobacco leaves. The soaking depth of the cigar tobacco leaves is controlled by the slide table 8. When the soaking time reaches the set time, the slide table 8 drives the cigar tobacco leaves to rise to the set height, which is the difference between the rising position of the cigar tobacco leaves and the origin control switch 6. The distilled water in the soaking water tank 18 can be automatically replenished through the water inlet pipe and the first solenoid valve 13. When the water level exceeds the water level detection switch 12, the water level detection switch 12 transmits a signal to close the first solenoid valve 13 and stop the water replenishment. When the soaking water tank 18 needs to be drained, the valve 16 can be opened to allow water to be discharged from the soaking water tank 18 through the water outlet pipe.

[0044] In one embodiment, the spray assembly includes a spray pipe 15 disposed within the housing, a second solenoid valve 17 disposed on the outer wall of the spray pipe 15, a plurality of nozzles 14 disposed at an angle toward the gripper assembly 19 on the outer wall of the spray pipe 15, a valve assembly disposed within the nozzles 14, a water outlet valve 23 disposed on one side of the outer wall of the spray tank 29, and one end of the spray pipe 15 being connected to the water outlet valve 23.

[0045] Specifically, when the spray assembly is working, the valve assembly inside the nozzle 14 is opened, and the second solenoid valve 17 is opened, allowing distilled water to be sprayed out from the nozzle 14 through the spray pipe 15. Optionally, there are twelve groups of nozzles 14, which are respectively arranged in front of the upper part, behind the upper part, in front of the lower part, and behind the lower part of the gripper assembly 19. Three nozzles 14 are evenly placed in each direction. Each nozzle 14 is inclined, with the upper nozzle 14 inclined downward and the lower nozzle 14 inclined upward, to ensure that the water mist sprayed from the nozzle 14 is directed towards the gripper assembly. The water sprayed from the nozzle 14 on the cigar tobacco leaf in component 19 is supplied by the spray tank 29. When spraying begins, the water outlet valve 23 is opened, and the nozzle 14 sprays water mist from the upper front, upper rear, lower front, and lower rear of the cigar tobacco leaf, so that the water mist evenly covers the surface of the cigar tobacco leaf. When the spraying time reaches the set value, the water outlet valve 23 is closed, and the nozzle 14 stops spraying. By adjusting the spraying time, the time that the water mist covers the surface of the cigar tobacco leaf can be adjusted, thereby adjusting the humidity of the cigar tobacco leaf and ensuring the practicality of the device.

[0046] like Figure 2As shown in one embodiment, a water pipe is provided on one side of the outer wall of the spray water tank 29, and a third solenoid valve 30 is provided on the outer wall of the water pipe. An upper water level switch 22 and a lower water level switch 27 are provided on the inner wall of the spray water tank 29. A heating tube 31 and a temperature sensor 26 are provided on the inner wall of the spray water tank 29. The lower water level switch 27 is located above the heating tube 31. A drain valve 28 is provided on one side of the bottom of the spray water tank 29. A water tank support 24 is provided at the bottom of the spray water tank 29, and multiple casters 25 are movably connected to the bottom of the water tank support 24.

[0047] In use, the heating element 31 heats the water in the spray tank 29, thereby adjusting the temperature of the water sprayed from the nozzle 14. When the spray tank 29 is automatically replenished, the third solenoid valve 30 opens. When the water level in the spray tank 29 reaches the upper water level switch 22, the third solenoid valve 30 closes. When the water level reaches the lower water level switch 27, the third solenoid valve 30 opens to perform automatic water replenishment. If the temperature of the water mist required for spraying needs to be higher than room temperature, the heating element 31 starts working. When the temperature sensor 26 detects that the water temperature has reached the set temperature, the heating element 31 stops working. To prevent dry burning, the lower water level switch 27 is set above the heating element 31. When the spray tank 29 is not used for a long time, the drain valve 28 can be opened to drain the water in the spray tank 29. The spray tank 29 is fixed on the tank bracket 24. The entire tank bracket 24 can be moved flexibly by the casters 25. When it is moved to the set position, the casters 25 can be locked to fix the position of the spray tank 29.

[0048] like Figure 3 As shown in one embodiment, a first air inlet 1 is provided on one side of the inner wall of the box, a working fan 2 is provided on one side of the inner wall of the box with the first air inlet 1, a first return air inlet 7 is provided on the inner wall of the box below the first air inlet 1, and a temperature and humidity sensor 3 is provided on the inner wall of the box; the constant temperature and humidity system includes an equipment box located inside the box, a compressor 33 is provided inside the equipment box, one end of the compressor 33 is connected to a condenser 34, and one end of the condenser 34 is connected to an evaporator 37, the evaporator... One end of 37 is connected to the compressor 33. A cooling fan 35 is provided on the inner wall of the equipment box on one side of the condenser 34. A second return air vent 36 is provided on the inner wall of the equipment box on one side of the cooling fan 35. A fan 38 is provided on the inner wall of the equipment box on one side of the evaporator 37. An electric heater 39 and a humidifying pipe 40 are provided on the inner wall of the equipment box on one side of the fan 38. A second air inlet 41 is provided on the inner wall of the equipment box on one side of the humidifying pipe 40. One end of the humidifying pipe 40 is connected to a humidifying box 32.

[0049] Specifically, the working fan 2 blows air with the required temperature and humidity into the chamber through the first air inlet 1, thereby adjusting the temperature and humidity inside the chamber. The return air is discharged through the first return air outlet 7. The temperature and humidity inside the chamber are monitored in real time by the temperature and humidity sensor 3. When the temperature and humidity sensor 3 detects that the temperature and humidity inside the chamber have reached the set value, the constant temperature and humidity system operates at a low power level to maintain the temperature and humidity inside the chamber within the set range, so that the cigar tobacco leaves are kept under constant temperature and humidity conditions for a long time. When the temperature and humidity equilibrium time reaches the set time value, the constant temperature and humidity system stops working, and the humidification and re-humidification of the cigar tobacco leaves stops. This function can precisely control the temperature and humidity of the cigar tobacco leaves, as well as the duration of equilibrium conditions. By setting different times, temperatures, and humidity levels, the humidity of the cigar tobacco leaves can be adjusted.

[0050] The working principle diagram of the constant temperature and humidity system is as follows: Figure 3 As shown, this system is the sum of four systems: a cooling system, a dehumidification system, a heating system, and a humidification system. Taking the most commonly used cooling and humidification system as an example, the refrigerant in the equipment box is compressed into a high-temperature, high-pressure refrigerant in the compressor 33, and then transported to the condenser 34 through pipelines. The condenser 34 liquefies the high-temperature refrigerant vapor compressed by the compressor 33, and the released heat is conducted to the external environment by the cooling fan 35. The liquefied refrigerant passes through the expansion valve and enters the evaporator 37. Under the action of the evaporator 37, the refrigerant exchanges heat with the air in the second return air inlet 36, and the refrigerant absorbs heat and vaporizes, returning to the compressor 33 through pipelines. The air that has cooled down after heat exchange is driven by the fan 38 and enters the box through the second air inlet 41. The air inside the box continuously circulates and exchanges heat until it reaches the desired temperature. The system sets the temperature value; when the set humidity value is higher than the humidity of the air inside the chamber, the distilled water in the humidifier 32 is humidified by the humidifier tube 40 and blown into the air by the fan 38, and then enters the chamber with the air circulation until the system set humidity value is reached; when both the temperature and humidity reach the system set temperature and humidity values, the compressor 33 and the humidifier tube 40 reduce their operating power to achieve a stable equilibrium state inside the chamber; if the temperature inside the chamber is lower than the set temperature value, the system does not cool, the electric heater 39 works, the fan 38 draws the air returning from the second return air port 36 and heats it through the electric heater 39 before it enters the chamber through the second air inlet 41; while the air is being heated and circulated, the humidity will decrease. If humidification is required at the same time, the humidifier tube 40 will work simultaneously to achieve the function of heating and humidifying.

[0051] In practice, click "Reset" on the control interface of the chamber. After the chamber is initialized, weigh the cigar tobacco sample and input the sample name and initial weight into the control interface. Fix the cigar tobacco in the gripper assembly 19, secure the rotating shaft 20, and close the chamber. Set the required process actions, including standing, inverting, soaking, standing spray, inverting spray, balancing, etc., which can be randomly combined. When setting each process action, set the corresponding parameters for each action. After setting, click the "Run" button, and the chamber will start working. After all process actions are completed, remove the cigar tobacco and weigh it. Input the current sample weight into the control interface, and the cigar tobacco humidification and rehydration process is complete.

[0052] This invention comprises four parts: automatic soaking, automatic spraying, automatic turning, and automatic temperature and humidity adjustment. Each part is automatically controlled and easy to operate. Through the constant temperature and humidity system, the humidity of cigar tobacco leaves can be controlled within a certain range, thereby achieving precise and controllable temperature and humidity for cigar tobacco leaf fermentation. The entire process can be fully automated, improving work efficiency and ensuring stability during operation. No manual processing is required, which facilitates the generation of quantitative data to support research on the cigar tobacco leaf humidification and rehydration process and fermentation temperature and humidity environmental parameters, ensuring the practicality of the device.

[0053] Example 2:

[0054] like Figure 4 As shown, the present invention provides a method for obtaining process parameters of humidification and rehumidification of cigar tobacco leaves, based on the humidification and rehumidification device of cigar tobacco leaves described in Embodiment 1, including the following steps:

[0055] Step a: Input the preset sample humidification results, and retrieve the dataset that is closest to the preset sample humidification results from the database to obtain the basic parameters;

[0056] Step b: Fine-tune the basic parameters and input the fine-tuned basic parameters into the pre-built and trained RNN model to obtain the predicted sample humidification results;

[0057] Step c: Determine whether the predicted sample humidification results meet the preset range;

[0058] If the judgment result is yes, the work ends, and the fine-tuned basic parameters are obtained;

[0059] If the result is negative, repeat step b until the predicted humidification result of the sample meets the preset range.

[0060] Specifically, the database consists of multiple datasets. The basic parameters in these datasets include: soaking time, water temperature, spraying time, spraying water temperature, spraying pressure, equilibrium time, equilibrium temperature and humidity, measured sample humidification results, sample brand number, and overall experimental plan. When obtaining these basic parameters, the pre-set sample humidification results for this experiment are first confirmed. Then, using these results as the target, the dataset most closely matching the pre-set sample humidification results is selected from the multiple datasets in the database, and its basic parameters are obtained. These basic parameters are then fine-tuned, and the fine-tuned parameters are input into a trained RNN model for calculation to obtain predicted sample humidification results. A pre-set range is obtained based on the pre-set sample humidification results, and it is determined whether the predicted sample humidification results fall within this range. This determines whether the fine-tuned basic parameters meet the experimental requirements. If they do, the basic parameters are confirmed; otherwise, they are readjusted. This fine-tuning process is repeated multiple times until the parameters meet the pre-set range, thus confirming the experimental plan and improving experimental efficiency.

[0061] The fine-tuning of the basic parameters includes: optimizing the basic parameters using a genetic algorithm, that is, optimizing the parameters required for the set temperature and humidity using a genetic algorithm. The genetic algorithm process includes selection, crossover, and mutation, such as... Figure 5 As shown.

[0062] The method for training the RNN model includes: inputting multiple datasets into the RNN model to establish a correlation model of complex nonlinear relationships between basic parameters and measured sample humidification results; the RNN model has a memory function, which can predict the quality changes of tobacco leaves after humidification and re-wetting based on set parameters, and each experiment adds new experimental parameters and results, which can be substituted into the RNN model for training, thereby enabling self-learning and training again, making the system adaptive and continuously iteratively optimizing the model; the training process of the RNN model is as follows: Figure 6 As shown, x represents the basic parameters in the dataset, s represents the hidden model equation, o represents the predicted humidification result, W represents the coefficient of variation from the hidden layer to the hidden layer, U represents the coefficient of variation from the input layer to the hidden layer, V represents the variability data from the hidden layer to the output layer, and t and Δt are preset values.

[0063] Specifically, the main steps of the entire cigar tobacco humidification and rehydration process are: soaking, spraying, and balancing. These three steps can be interleaved and repeated. The soaking step allows setting two parameters: soaking time and water temperature. The spraying step allows setting the spraying time, spraying water temperature, and spraying pressure. The balancing step allows setting the balancing time and balancing temperature and humidity, and the temperature and humidity can also be programmed to increase or decrease at set intervals. Before and after the experiment, each cigar tobacco leaf is weighed, and the system automatically saves the data, including the weight gain ratio before and after the experiment, to evaluate the humidification and rehydration effect. After the experiment, the humidification and rehydration effect is manually evaluated and scored. As experimental data accumulates, multiple datasets can be formed and a database can be created. The system can use an RNN model to train a complex nonlinear relationship model between basic parameters and the measured humidification results of samples, and then assist researchers in optimizing experimental plans to improve research efficiency.

[0064] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
