[0004] To address this, the present invention provides an intelligent tobacco dehumidification and humidification module and a tobacco curing device, which overcomes the problems of high energy consumption caused by directly heating tobacco leaves and reduced curing effect due to excessively low humidity in the prior art.

[0005] To achieve the above objectives, this utility model provides a tobacco curing device, including a housing, and further comprising:

[0006] A heating mechanism, connected to the housing, is used to heat the tobacco leaves;

[0007] A cooling and dehumidifying mechanism, which is connected to the heating mechanism, is used to absorb heat from high-humidity and high-temperature gas and remove water vapor from the high-humidity and high-temperature gas.

[0011] A condenser, located at the top of the casing, is used to heat the tobacco storage space;

[0012] A liquid storage tank, which is connected to the condenser, is used to store the condensate in the condenser;

[0013] A gas-liquid separator, connected to the storage tank, is used to separate low-pressure, low-temperature gas and liquid from the condensate.

[0014] A compressor, connected to the gas-liquid separator, is used to compress the low-pressure, low-temperature gas into a high-pressure, high-temperature gas.

[0015] Furthermore, the first heat absorption and dehumidification component includes:

[0016] An air inlet is used to introduce high-humidity and high-temperature gas from the tobacco storage space into the first space inside the shell;

[0017] A dehumidifying evaporator, which is connected to the core heat exchanger, is used to absorb heat and dehumidify the high-humidity and high-temperature gas in the first space to form the low-temperature and low-humidity gas and deliver it to the core heat exchanger.

[0018] A core heat exchanger, which is connected to the dehumidifying evaporator, is used to exchange heat between the high-humidity and high-temperature gas and the low-temperature and low-humidity gas to form high-humidity and low-temperature gas and low-humidity and high-temperature gas respectively.

[0019] A dehumidifying fan, connected to the core heat exchanger, is used to transfer the low-humidity, high-temperature gas to the condenser.

[0020] Furthermore, the second heat-absorbing component includes:

[0021] A dehumidifying fan is installed on the condenser side near the dehumidifying evaporator to introduce the high-humidity, high-temperature gas in the first space into the second space inside the casing;

[0022] A heat-absorbing evaporator is disposed on the inner wall of the housing away from the air inlet, for absorbing heat and dehumidifying the high-humidity and high-temperature gas in the second space to form a low-temperature and low-humidity gas;

[0023] Several external rotor evaporator fan units are installed on the outer wall of the casing away from the air inlet, for discharging the low-temperature, low-humidity gas in the second space to the outside of the casing.

[0024] Furthermore, each of the aforementioned external rotor evaporator fan units includes a first external rotor evaporator fan and a second external rotor evaporator fan, and each external rotor evaporator fan unit is arranged at equal intervals along the vertical direction;

[0026] Furthermore, the angle between the upper surface of the condenser and the upper surface of the shell is an acute angle.

[0027] Furthermore, the pressure detection mechanism includes a plurality of pressure gauges, wherein the sensing connectors of the pressure gauges are respectively disposed on the inner wall of the gas-liquid separator, the inner wall of the compressor, the interior of the core heat exchanger, the inner wall of the shell in the first space, the inner wall of the shell in the second space, and the interior of the condenser.

[0028] Furthermore, the gas-liquid separator is equipped with a gas-liquid separation copper tube for discharging low-pressure, low-temperature gas from the condensate into the second space.

[0029] Furthermore, the humidification mechanism includes:

[0030] A humidifying copper pipe, which is connected to the condenser, is used to discharge the high-temperature, low-humidity gas in the condenser to the tobacco storage space;

[0031] An air inlet is located on the upper surface of the housing to allow low-temperature, low-humidity gas from outside the housing to enter the housing and mix with the high-temperature, low-humidity gas in the condenser.

[0032] This utility model also provides an intelligent dehumidification and humidification module, including a cooling and dehumidification mechanism and a humidification mechanism in a tobacco curing device.

[0033] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting up a heating mechanism, a cooling and dehumidifying mechanism, a humidifying mechanism, and a pressure detection mechanism, this utility model absorbs heat and cools and dehumidifies the high-temperature and high-humidity gas containing water vapor evaporated from the tobacco leaves, thereby reducing the humidity of the tobacco storage space and increasing the curing effect. By absorbing the heat from the high-temperature and high-humidity gas, the temperature of the heating mechanism is increased, reducing the energy consumption caused by directly heating the tobacco storage space. The low-humidity gas introduced by the humidifying mechanism avoids the decline in the curing effect caused by excessively low humidity, maintains the appropriate humidity of the tobacco leaves, and thus improves the quality of the cured tobacco. By setting up a pressure detection mechanism, the pressure status inside the tobacco curing device is monitored in real time, thereby improving the stability and safety of the tobacco curing process.

[0034] Furthermore, the device described in this utility model effectively condenses and recovers the high-temperature and high-humidity gas generated during the tobacco curing process by setting up a condenser, a liquid storage tank, a gas-liquid separator, and a compressor. The condenser releases the heat absorbed from the high-temperature and high-humidity gas into the tobacco storage space, improving heat exchange efficiency. The liquid storage tank stores the condensate, ensuring the continuity and stability of the device's operation. The gas-liquid separator further separates the gas and liquid, reducing the damage caused by liquid entering the compressor. The compressor recompresses the gas, increasing its temperature and pressure, so that it can be recycled back into the heating mechanism, thereby improving energy utilization.

[0035] Furthermore, the device described in this utility model, by setting up an air inlet, a dehumidifying evaporator, a core heat exchanger, and a dehumidifying fan, allows high-humidity and high-temperature external air to enter the tobacco curing device and exchange heat with the low-humidity and low-temperature gas output by the internal dehumidifying evaporator to achieve a cooling function; the dehumidifying evaporator uses the condensation principle to condense water vapor in the humid and hot air into water droplets and discharge them, further reducing humidity; the low-humidity and low-temperature gas in the core heat exchanger absorbs heat from the high-humidity and high-temperature gas and transfers it to the condenser, realizing internal circulation heat exchange and reducing the energy consumption of the tobacco curing device.

[0036] Furthermore, the device described in this utility model is equipped with a dehumidifying fan, a heat-absorbing evaporator, and an external rotor evaporating fan unit. The dehumidifying fan discharges the incompletely treated high-humidity and high-temperature gas inside the tobacco curing device to maintain a dry internal environment. The heat-absorbing evaporator further absorbs the heat from the discharged air and recovers and utilizes the heat through a condensation process, thereby reducing heat waste. The external rotor evaporating fan unit maintains a uniform distribution of temperature and humidity inside the device through air circulation, thus improving the efficiency of tobacco curing.

[0037] Furthermore, the device of this invention improves the processing efficiency and uniformity of high-humidity gases by setting up external rotor evaporation fans arranged at equal intervals to process the gas at corresponding positions in the second space.

[0038] Furthermore, the device of this invention, by setting an inclined condenser, allows the condensate to be discharged more quickly during operation due to gravity, reducing the accumulation of condensate inside the condenser. This improves the condensate circulation efficiency and reduces the corrosive effect of condensate on the condenser material. At the same time, it prevents air from accumulating inside the condenser, improving heat exchange efficiency. The inclined condenser occupies less parallel space while the inclined surface of the condenser improves heat exchange efficiency. The inclined condenser also prevents heat dissipation from directly facing the tobacco leaves, reducing the decrease in the tobacco curing effect caused by direct roasting of tobacco leaves near the curing device, thus improving heat exchange efficiency.

[0039] Furthermore, the device described in this utility model uses several pressure gauges to detect the pressure at various locations within the device, thereby determining the pressure in each space. Since the flowing gases within the device exchange heat with each other to achieve the dehumidification effect of condensing water vapor, pressure changes occur within the device, which in turn impacts the internal structure. By detecting the pressure, the stability of the device's operation is improved.

[0040] Furthermore, the device described in this utility model is equipped with a gas-liquid separation copper pipe, a humidification copper pipe, and an air inlet. The gas-liquid separation copper pipe prevents gas from entering the compressor and causing damage to the compressor. The humidification copper pipe humidifies the tobacco leaves by supplying gas containing water vapor to the tobacco storage space, ensuring that the tobacco leaves maintain a suitable humidity during the curing process and avoiding the impact of low humidity on the quality of the cured tobacco. This increases the stability of the tobacco curing device and the curing effect. Attached Figure Description

[0051] A heating mechanism, which is connected to the housing 14, is used to heat the tobacco leaves;

[0052] A cooling and dehumidifying mechanism, which is connected to the heating mechanism, is used to absorb heat from high-humidity and high-temperature gas and remove water vapor from the high-humidity and high-temperature gas. It includes a first heat-absorbing and dehumidifying component for first cooling and dehumidifying the high-humidity and high-temperature gas to discharge high-temperature and low-humidity gas, and a second heat-absorbing and dehumidifying component connected to the first heat-absorbing and dehumidifying component for second cooling and dehumidifying the high-humidity and high-temperature gas to form low-temperature and low-humidity gas.

[0053] A humidification mechanism, connected to the heating mechanism, is used to humidify the tobacco leaves;

[0054] A pressure detection mechanism, which is connected to the dehumidification mechanism, the humidification mechanism and the heating mechanism, is used to detect the pressure inside the housing 14.

[0055] Specifically, the device described in this utility model further includes:

[0056] The electrical box (not shown in the figure) is connected to the housing 14 and is used to supply power to the internal components of the device;

[0057] Electrical box door 19, which is connected to housing 14, is used to seal the electrical box space inside housing 14.

[0058] The LCD screen 18 is connected to the electrical box door 19 and is used to display the working status of the device;

[0059] The operating status of the device includes: voltage detected by several voltmeters, power of dehumidifying evaporator 4, speed of dehumidifying fan 2, speed of exhaust fan 12, power of heat absorption evaporator 11, and speed of external rotor evaporating fan 10.

[0060] Specifically, the working process of the device described in this utility model is as follows: the air inlet 15 introduces the high-humidity and high-temperature gas from the tobacco storage space into the first space inside the shell 14. The high-humidity and high-temperature gas is cooled by the core heat exchanger 3 to form high-humidity and low-temperature gas. A portion of the high-humidity and low-temperature gas and a portion of the high-temperature and high-humidity gas that has not fully exchanged heat enter the dehumidification evaporator 4 for heat absorption and dehumidification, and the low-temperature and low-humidity gas is discharged. The low-temperature and low-humidity gas enters the core heat exchanger 3 to exchange heat with the subsequently entering high-humidity and high-temperature gas to form low-humidity and high-temperature gas, which is then discharged to the condenser 1 by the dehumidification fan 2. A portion of the high-humidity and low-temperature gas passing through the first space... A portion of the high-temperature and high-humidity gas that has not fully exchanged heat is introduced into the second space by the exhaust fan 12, and is cooled and dehumidified by the heat-absorbing evaporator 11 to form low-humidity and low-temperature gas. The low-humidity and low-temperature gas is discharged to the outside of the shell 14 by the external rotor evaporator fan 10. The heat absorbed by the heat-absorbing evaporator 11 and the dehumidifying evaporator 4 is transferred to the condenser 1. The humidification mechanism introduces the low-temperature and low-humidity gas outside the shell 14, and the humidification copper pipe 13 outputs the high-temperature and low-humidity gas in the condenser 1. The low-temperature and low-humidity gas outside the shell 14 and the high-temperature and low-humidity gas in the condenser 1 are mixed and output to the tobacco storage space for humidification through the heat exhaust port 16.

[0061] Specifically, the dehumidification process of the heat-absorbing evaporator 11 and the dehumidifying evaporator 4 is as follows: high-humidity gas enters the heat-absorbing evaporator 11 or the dehumidifying evaporator 4 and flows and absorbs heat in it. The water vapor in the high-humidity gas gradually evaporates into steam, and the steam content increases. When it flows to the outlet of the heat-absorbing evaporator 11 or the dehumidifying evaporator 4, it forms low-humidity gas. When it reaches the end of the heat-absorbing evaporator 11 or the dehumidifying evaporator 4, it continues to absorb heat and forms superheated steam.

[0062] Specifically, the heating mechanism includes:

[0063] Condenser 1, which is located on the top of housing 14, is used to heat the tobacco storage space;

[0064] A liquid storage tank 6, which is connected to the condenser 1, is used to store the condensate in the condenser 1;

[0065] Gas-liquid separator 8, which is connected to the liquid storage tank 6, is used to separate low-pressure, low-temperature gas and liquid in the condensate.

[0066] The compressor 9, which is connected to the gas-liquid separator 8, is used to compress the low-pressure, low-temperature gas into a high-pressure, high-temperature gas.

[0067] In practice, this invention utilizes a heating mechanism, a cooling and dehumidification mechanism, a humidification mechanism, and a pressure detection mechanism. These mechanisms absorb heat from the high-temperature, high-humidity gas containing water vapor evaporated from the tobacco leaves, thereby reducing the humidity in the tobacco storage space and improving the flue-curing effect. By absorbing heat from the high-humidity, high-temperature gas, the temperature of the heating mechanism is increased, reducing energy consumption caused by directly heating the tobacco storage space. The introduction of low-humidity gas through the humidification mechanism prevents a decline in flue-curing effect due to excessively low humidity, maintaining suitable humidity for the tobacco leaves and thus improving the quality of the flue-cured tobacco. Finally, the pressure detection mechanism monitors the internal pressure of the flue-curing device in real time, improving the stability and safety of the flue-curing process.

[0068] Specifically, the first heat absorption and dehumidification component includes:

[0069] The air inlet 15 is used to introduce the high humidity and high temperature gas in the tobacco storage space into the first space inside the housing 14;

[0070] The dehumidifying evaporator 4 is connected to the core heat exchanger 3 and is used to absorb heat and dehumidify the high-humidity and high-temperature gas in the first space to form the low-temperature and low-humidity gas and transport it to the core heat exchanger 3.

[0071] The core heat exchanger 3 is connected to the dehumidifying evaporator 4 and is used to exchange heat between the high humidity and high temperature gas and the low temperature and low humidity gas to form high humidity and low temperature gas and low humidity and high temperature gas respectively.

[0072] The dehumidifying fan 2 is connected to the core heat exchanger 3 and is used to transfer the low-humidity, high-temperature gas to the condenser 1.

[0073] In practice, the device of this utility model is equipped with an air inlet 15, a dehumidifying evaporator 4, a core heat exchanger 3, and a dehumidifying fan 2. The air inlet 15 allows high-humidity and high-temperature air from outside to enter the tobacco curing device and exchange heat with the low-humidity and low-temperature gas output from the internal dehumidifying evaporator 4 to achieve a cooling function. The dehumidifying evaporator 4 uses the condensation principle to condense water vapor in the humid and hot air into water droplets and discharge them, further reducing humidity. The low-humidity and low-temperature gas in the core heat exchanger 3 absorbs heat from the high-humidity and high-temperature gas and transfers it to the condenser 1, realizing internal circulation heat exchange and reducing the energy consumption of the tobacco curing device.

[0074] Specifically, the second heat-absorbing component includes:

[0075] A dehumidifying fan 12 is located on the side of the condenser 1 near the dehumidifying evaporator 4, and is used to introduce the high humidity and high temperature gas in the first space into the second space inside the housing 14;

[0076] A heat-absorbing evaporator 11 is disposed on the inner wall of the housing 14 away from the air inlet 15, for absorbing heat and dehumidifying the high-humidity and high-temperature gas in the second space to form a low-temperature and low-humidity gas.

[0077] A plurality of external rotor evaporator fans 10 are arranged on the outer wall of the housing 14 away from the air inlet 15, for discharging the low-temperature and low-humidity gas in the second space to the outside of the housing 14.

[0078] In practice, the device of this invention uses external rotor evaporators 10 arranged at equal intervals to process the gas at corresponding positions in the second space, thereby improving the processing efficiency and uniformity of high-humidity gas.

[0079] In practice, the device of this utility model is equipped with a dehumidifying fan 12, a heat-absorbing evaporator 11, and 10 sets of external rotor evaporating fans. The dehumidifying fan 12 discharges the untreated high-humidity and high-temperature gas inside the tobacco curing device to maintain a dry internal environment. The heat-absorbing evaporator 11 further absorbs the heat from the discharged air and recovers and utilizes the heat through a condensation process, thereby reducing heat waste. The 10 sets of external rotor evaporating fans maintain a uniform distribution of temperature and humidity inside the device by circulating air, thus improving the efficiency of tobacco curing.

[0080] Specifically, each of the 10 sets of external rotor evaporators includes a first external rotor evaporator and a second external rotor evaporator, and each 10 sets of external rotor evaporators is arranged at equal intervals along the vertical direction.

[0081] The first external rotor evaporator and the second external rotor evaporator are axially symmetrical about the vertical line of symmetry of the outer wall of the housing 14 away from the air inlet 15.

[0082] Specifically, the number of external rotor evaporator fans 10 is positively correlated with the length and width of the surface of the housing 14 connected to them. For example, if the length of the surface of the housing 14 connected to the external rotor evaporator fan 10 is 1.5m and the width is 1.1m, and the diameter of the external rotor evaporator fan 10 is 0.2m, then the external rotor evaporator fans 10 are arranged symmetrically with two fans per row for a total of three rows.

[0083] Specifically, the angle between the upper surface of the condenser 1 and the upper surface of the housing 14 is an acute angle.

[0084] In practice, the device of this utility model, by setting an inclined condenser 1, allows the condensate to be discharged more quickly during operation due to gravity, reducing the accumulation of condensate inside the condenser 1. This improves the condensate circulation efficiency and reduces the corrosive effect of condensate on the condenser 1 material. At the same time, it prevents air from accumulating inside the condenser 1, improving heat exchange efficiency. The inclined condenser 1 occupies less parallel space while the inclined surface of the condenser 1 improves heat exchange efficiency. The inclined condenser 1 also prevents heat dissipation from directly facing the tobacco leaves, reducing the decrease in the tobacco curing effect caused by direct roasting of tobacco leaves near the curing device, thus improving heat exchange efficiency.

[0085] Specifically, the upper surface of the housing 14 near the condenser 1 is provided with a heat exhaust port 16 for discharging the low-humidity, high-temperature gas.

[0086] Specifically, the pressure detection mechanism includes a plurality of pressure gauges 5, wherein the sensing connectors of the pressure gauges 5 are respectively disposed on the inner wall of the gas-liquid separator 8, the inner wall of the compressor 9, the interior of the core heat exchanger 3, the inner wall of the housing 14 in the first space, the inner wall of the housing 14 in the second space, and the interior of the condenser 1.

[0087] In practice, the device described in this utility model uses several pressure gauges 5 to detect the pressure at various locations within the device, thereby determining the pressure in each space. As the flowing gases within the device exchange heat with each other to achieve the dehumidification effect of condensing water vapor, pressure changes occur within the device, which in turn impacts the internal structure. By detecting the pressure, the stability of the device's operation is improved.

[0088] Specifically, the gas-liquid separator 8 is equipped with a gas-liquid separation copper tube 7 for discharging low-pressure, low-temperature gas from the condensate into the second space.

[0089] Specifically, the humidification mechanism includes:

[0090] Humidifying copper pipe 13 is connected to the condenser 1 to discharge the high-temperature, low-humidity gas in the condenser 1 to the tobacco storage space;

[0091] Air inlet 17 is provided on the upper surface of the housing 14 to allow low-temperature, low-humidity gas from outside the housing 14 to enter the housing 14 and mix with the high-temperature, low-humidity gas in the condenser 1.

[0092] In practice, the device of this utility model is equipped with a gas-liquid separation copper pipe 7, a humidification copper pipe 13, and an air inlet 17. The gas-liquid separation copper pipe 7 prevents gas from entering the compressor 9 and causing damage to the compressor 9. The humidification copper pipe 13 humidifies the tobacco leaves by supplying gas containing water vapor to the tobacco storage space, ensuring that the tobacco leaves maintain a suitable humidity during the curing process and avoiding the impact of low humidity on the quality of the cured tobacco. This increases the stability of the tobacco curing device and the curing effect.

[0093] This utility model also provides an intelligent dehumidification and humidification module, including a cooling and dehumidification mechanism and a humidification mechanism in a tobacco curing device.

[0094] The technical solution of this utility model has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
