Technical Field

[0001] The present invention relates to the field of tea processing, and particularly to an integrated piling fermentation and drying multifunctional machine and its control method. Background Art

[0002] With the development of the times, drinking tea is popular among people of all ages, which greatly promotes the development of the tea processing industry. At present, there are various tea processing methods. Among them, piling, fermentation, and drying of tea are relatively common processing methods in tea processing. These three methods are completely different, that is, the temperature and humidity environments required during processing are different. Therefore, in order to ensure the processing environments of these three methods, in the prior art, the above three different tea processing methods are carried out in different spaces. In this way, it is necessary to move the tea, and a large tea processing site is required. Moreover, the accuracy and convenience of the existing equipment for controlling the temperature and humidity of the tea processing environment are also relatively limited. Therefore, it is very necessary to propose an integrated piling fermentation and drying multifunctional machine and its control method. Summary of the Invention

[0003] The purpose of the present invention is to provide an integrated piling fermentation and drying multifunctional machine and its control method, which can better adapt to and control the temperature and humidity environments required for different processing methods, and can more accurately and conveniently complete the temperature and humidity control of the tea processing environment, so as to solve the existing technical defects and unmet technical requirements.

[0004] To achieve the above purpose, the present invention provides the following technical solution: An integrated piling fermentation and drying multifunctional machine, including:

The humidification water tank is arranged on the steel frame, and an ultrasonic atomizer is arranged therein. The humidification fan is arranged outside the humidification water tank and is communicated with the humidification water tank. One end of the humidification pipeline is connected to the humidification water tank, and the other end extends into the fermentation chamber or the drying room. After the ultrasonic atomizer atomizes the water in the humidification water tank, the humidification fan transports the atomized water into the fermentation chamber or the drying room through the humidification pipeline;

The heating component includes a heat conduction oil tank, a heat conduction oil pipeline, a heat conduction oil pump, an explosion-proof heater, a heat exchanger, a circulation fan, and an air supply pipeline. The heat conduction oil pump, the explosion-proof heater, and the heat exchanger are sequentially connected in a head-to-tail cycle through the heat conduction oil pipeline. The input end of the heat conduction oil pump is connected to the heat conduction oil tank through the heat conduction oil pipeline. The air supply pipeline is connected to the heat exchanger, and a circulation fan is arranged thereon;

[0008] In this application, it should be further explained that the above description can be understood as follows: the heat-conducting oil tank is connected to the input end of the heat-conducting oil pump, the output end of the heat-conducting oil pump is connected to the input end of the explosion-proof heater, the output end of the explosion-proof heater is connected to the input end of the heat exchanger, and the output end of the heat exchanger is connected to the heat-conducting oil pump. The above connections are all made through heat-conducting oil pipes, so as to complete the circulation of the heat-conducting oil in the heat-conducting oil pump, the explosion-proof heater and the heat exchanger. The heat-conducting oil pump transports the oil in the heat-conducting oil tank to the explosion-proof heater through the heat-conducting oil pipe, then transports the oil heated by the explosion-proof heater to the heat exchanger, and finally transports the oil in the heat exchanger back to the heat-conducting oil pump. The circulation fan transports the air in the fermentation chamber or drying room to the air supply pipeline, and the air in the supply pipeline is discharged back into the fermentation chamber or drying room after heat exchange through the heat exchanger;

[0010] In this application, when the humidity in the tea space is relatively high, but the tea processing requires a relatively low humidity environment, the moisture exhaust fan in the moisture exhaust component is turned on, and the moisture in the fermentation chamber or drying room is discharged through the moisture exhaust channel to reduce the humidity in the tea space.

[0011] The integrated piling fermentation and drying multifunctional machine has different working modes, which can meet the piling fermentation of tea, the fermentation of black tea, and the drying process of tea cakes.

[0012] Because there are certain commonalities in the temperature and humidity control and ventilation control among the three processes of piling fermentation, black tea fermentation, and tea cake drying, the integrated piling fermentation and drying multifunctional machine integrates them in an innovative way. In the operation mode setting interface of the equipment, the user can select the piling fermentation mode, black tea fermentation mode, and drying mode of the equipment to switch the usage method of the integrated piling fermentation and drying multifunctional machine, so as to complete the piling fermentation of tea, the fermentation of black tea, and the drying of tea cakes.

[0020] Preferably, it further includes a central controller. The circulation fan, ultrasonic atomizer, heat conduction oil pump, humidifying fan, dehumidifying fan and detection component are all electrically connected to the central controller. A touch display screen is also connected to the controller, which is used to display the data content detected by the detection component, as well as to display and control the operation parameters and operation status of each fan.

[0021] In this application, the combination of the central controller and the touch display screen can be understood as another form of computer, that is, a computer, which is equipped with a control system and can be manually operated and automatically regulated according to the actual use situation.

[0022] Among them, the display content on the touch display screen includes but is not limited to: the operation status and data parameters of each motor, the data content detected by each detection component, the parameter range during the operation of each motor, the set range of the parameters detected by each detection component, historical operation data, alarm records after the parameters exceed the set range, historical information of manual operations, the operation permissions of operators and the verification of the identities of operators. Among them, the parameter range and equipment operation can be manually set by humans.

[0023] Preferably, a distribution box is also arranged on the steel frame. A power supply switch is arranged in the distribution box. One end of the power supply switch is electrically connected to each electrical appliance, and the other end is electrically connected to a power supply component for supplying power to each electrical appliance. The controller is arranged in the distribution box, and the touch display screen is arranged on the door of the distribution box.

[0024] Preferably, the following are also arranged on the steel frame:

[0025] Water filling port, which is communicated with the humidifying water tank. A float valve is arranged at one end of the water filling port close to the inside of the humidifying water tank, which is used to ensure the normal water level of the humidifying water tank;

[0026] Humidifying port, which is arranged at one end of the humidifying pipeline far from the humidifying water tank and is used to transport the atomized water into the fermentation chamber or drying room;

[0027] First dehumidifying port, which is arranged at one end of the dehumidifying pipeline extending into the fermentation chamber or drying room;

[0028] The second row of moisture outlets, and the second row of moisture outlets are arranged at one end of the moisture exhaust pipe far from the fermentation chamber or the drying room.

[0029] Preferably, the air delivery pipe includes:

[0030] An air inlet pipe, one end of the air inlet pipe is communicated with the heat exchanger, and the other end is communicated with the air inlet opening arranged on the steel frame;

[0031] An air outlet pipe, one end of the air outlet pipe is communicated with the air inlet pipe through the heat exchanger, and the other end is communicated with the air outlet opening arranged on the steel frame.

[0032] Preferably, it further includes a heat exchanger cleaning port, and the heat exchanger cleaning port is opened on the outer wall of the heat exchanger.

[0033] Preferably, the temperature and humidity sensor is arranged at the center of the fermentation chamber or the drying room and is far from the steel frame.

[0034] Preferably, an exhaust pipe is further connected to the explosion-proof heater, one end of the exhaust pipe far from the explosion-proof heater is connected to the heat conduction oil tank, and an air valve is arranged on the exhaust pipe.

[0035] Preferably, it further includes an alarm, the alarm is arranged on the door of the distribution box, one end of the alarm is connected to the controller, and the other end is connected to the power supply switch.

[0036] A control method for an integrated piling fermentation and drying multifunctional machine includes the following steps:

[0037] 1. Detect the current temperature and humidity data in the fermentation chamber or the drying room through the temperature and humidity sensor;

[0038] 2. Set the target temperature and humidity parameters in the fermentation chamber or the drying room respectively according to the temperature and humidity processing environments required for the piling fermentation of tea leaves, the fermentation of tea leaves, and the drying of tea cakes;

[0039] 3. Compare the target temperature and humidity parameters in step 2 with the current temperature and humidity data in step 1. If the current temperature and humidity data do not meet (are lower than) the target temperature and humidity parameters, continue the regulation through step 4. If the current temperature and humidity data are higher than the target temperature and humidity parameters, conduct the regulation through step 5;

[0040] 4. Start the humidification component and the heating component to regulate the temperature and humidity in the fermentation chamber or the drying room

[0041] 4.1) Turn on the ultrasonic atomizer. The ultrasonic atomizer atomizes the water in the humidification water tank, and the humidification fan inputs the atomized water into the fermentation chamber or the drying room through the humidification pipe, while ensuring that there is enough water in the humidification water tank;

[0042] Among them, a water filling port and a float valve are provided in this application. The water filling port is always connected to a water source. When the ultrasonic atomizer consumes the water in the humidifying water tank, the water level in the humidifying water tank drops. When the water level in the humidifying water tank is lower than the set height, the float valve opens, and the water filling port replenishes water to the humidifying water tank. When the water level reaches the preset height, the float valve closes to prevent the water level from being too high and overflowing the humidifying water tank, ensuring that the water level in the humidifying water tank is always at a reasonable height.

[0043] 4.2), sequentially turn on the explosion-proof heater, heat exchanger, heat-conducting oil pump, and circulation fan, so that the heat-conducting oil circulates through the heat-conducting oil pipe among the heat-conducting oil pump, explosion-proof heater, heat exchanger, and heat-conducting oil pump in sequence. The circulation fan inhales the air in the fermentation chamber or drying room to the heat exchanger for heat exchange, and then conveys the heat-exchanged air back to the fermentation chamber or drying room;

[0044] When the heating component or the humidifying component is started, the detection component is started accordingly. Among them, the temperature and humidity sensor is always in a working state. And it needs to be further explained that when the current temperature and humidity data is lower than the target temperature and humidity parameters, the central control system will automatically identify the difference between the two and generate other equipment parameters during the temperature and humidity regulation, such as the operating parameters of the humidifying fan, the parameters of the ultrasonic atomizer, the operating parameters of the heat-conducting oil pump, the parameters of the oil temperature, the flow parameters in the oil pipe, the oil pressure parameters in the oil pipe, the operating parameters of the explosion-proof heater, and the operating parameters of the circulation fan, etc. When setting the above parameters, the operating states of some parameters and equipment need to be adjusted in real time according to the real-time feedback of the detection component.

[0045] 4.3), when the temperature and humidity sensor detects that the temperature and humidity data in the fermentation chamber or drying room reaches the target temperature and humidity parameters, stop the temperature and humidity regulation in steps 4.1) and 4.2);

[0046] V. Start the moisture exhaust fan to exhaust the air in the tea space out of the fermentation chamber or drying room. When the temperature and humidity sensor measures that the temperature and humidity data in the fermentation chamber or drying room is the same as the target temperature and humidity parameters, turn off the moisture exhaust fan.

[0047] Compared with the prior art, the beneficial effects of the present invention are:

[0048] 1. In this application, by setting a heating component, a humidifying component, a detection component, and a moisture exhaust component, and through the intelligent regulation of the touch display screen and the controller with a control system, the temperature and humidity regulation can be completed more accurately through the detection component. Through the setting of intelligent control, the regulation of temperature and humidity can be made more convenient, enabling this integrated device in this application to simultaneously regulate the temperature and humidity of the same fermentation chamber or drying room, adjust the parameters of the tea piling, fermentation, and drying processing environments according to different usage situations, improve adaptability, and reduce the usage space.

[0049] 2. By setting up a heating component and adopting the principle of hot air heating, the whole machine can uniformly, stably and rapidly raise the temperature of the production chamber, greatly improving the processing quality and significantly increasing the utilization rate of electric energy. At the same time, the production efficiency of tea is greatly improved, and the production cost is also greatly saved.

[0050] 3. The principle of ultrasonic atomization humidification in this application is to convert electric energy into mechanical energy by the atomizer module at the bottom of the water tank, adopt electronic ultra-high frequency oscillation, and generate atomized water through the high-frequency resonance of the atomizing sheet, so as to achieve the purpose of isenthalpic humidification of air. Ultrasonic atomization humidification is uniform, the relative humidity increases rapidly, and the humidification efficiency is high. BRIEF DESCRIPTION OF THE DRAWINGS

[0064] In this embodiment, by combining the humidifying assembly using atomizing humidification and the heating assembly for air supply and heating, the temperature of the production chamber of the whole machine can rise evenly, stably and quickly, greatly improving the processing quality, and at the same time greatly improving the utilization rate of electric energy; the production efficiency of tea is greatly improved, and of course the production cost is also greatly saved. At the same time, the principle of ultrasonic atomizing humidification is to convert electric energy into mechanical energy by the atomizer module at the bottom of the water tank, adopt electronic over-frequency oscillation, generate atomized water through the high-frequency resonance of the atomizing sheet, so as to achieve the purpose of isenthalpic humidification of air. And ultrasonic atomizing humidification is uniform, the relative humidity increases rapidly, and the humidification efficiency is high.

[0065] The detection assembly includes:

[0066] A pipeline pressure gauge, the pipeline pressure gauge is arranged on the heat-conducting oil pipe 5 for detecting the internal pressure of the heat-conducting oil pipe 5;

[0067] A flowmeter 10, the flowmeter 10 is arranged on the heat-conducting oil pipe 5 for detecting the flow rate in the heat-conducting oil pipe 5;

[0068] An oil temperature sensor, the oil temperature sensor is arranged on the explosion-proof heater 7 for detecting the temperature of the oil in the explosion-proof heater 7;

[0071] It further includes a central controller. The circulation fan 9, the ultrasonic atomizer, the heat conduction oil pump 6, the humidifying fan, the dehumidifying fan and the detection component are all electrically connected to the central controller. A touch display screen 11 is also connected to the controller, which is used to display the data content detected by the detection component, and display and control the operation parameters and operation states of each fan.

[0072] In this embodiment, through the intelligent regulation and control of the touch display screen 11 and the controller with a control system, the detection component can more accurately complete the regulation of temperature and humidity. Through the setting of intelligent control, the regulation of temperature and humidity can be made more convenient, enabling the integrated device of this application to simultaneously regulate the temperature and humidity of the same fermentation chamber, and adjust the parameters of the pile-fermentation, fermentation and drying processing environments of tea according to different usage situations, improving adaptability and reducing the usage space.

[0073] A distribution box 12 is further arranged on the steel frame 1. A power supply switch is arranged in the distribution box 12. One end of the power supply switch is electrically connected to each electrical appliance, and the other end is electrically connected to a power supply component for supplying power to each electrical appliance. The controller is arranged in the distribution box 12, and the touch display screen 11 is arranged on the door of the distribution box 12.

[0074] Specifically, in this embodiment, the three-phase power line in the distribution box 12 must be made of copper wire with a diameter of not less than 6mm 2 , the neutral wire is not less than 4mm 2 , and the grounding protection wire is not less than 4mm 2 , and the voltage of the power supply component is 380V.

[0075] The following are also arranged on the steel frame 1:

[0076] A water filling port 13, which is communicated with the humidifying water tank 2. A float valve is arranged at one end of the water filling port 13 close to the inside of the humidifying water tank 2 to ensure the normal water level of the humidifying water tank 2; and a filter (60 - 80 meshes) is installed on the pipeline of the water filling port 13.

[0077] A humidifying port 14, which is arranged at one end of the humidifying pipeline 3 far from the humidifying water tank 2 and is used to convey the atomized water into the fermentation chamber;

[0078] A first dehumidifying port 15, which is arranged at one end of the dehumidifying pipeline extending into the fermentation chamber;

[0079] The second row of moisture outlets 16 is provided at one end of the moisture exhaust pipe away from the fermentation chamber. The steel frame 1 is further provided with:

[0080] The air delivery pipe includes:

[0081] An air inlet pipe, one end of which is communicated with the heat exchanger 8, and the other end is communicated with the air inlet 17 provided on the steel frame 1;

[0082] An air outlet pipe 18, one end of which is communicated with the air inlet pipe through the heat exchanger 8, and the other end is communicated with the air outlet 19 provided on the steel frame 1, and a hot air sensor is arranged at the air outlet 19.

[0083] It further includes a heat exchanger cleaning port 20, which is opened on the outer wall of the heat exchanger 8.

[0084] After long-term operation, there may be sundries on the heat exchanger 8, and too many will affect the operation of the heat exchanger 8. Therefore, the heat exchanger cleaning port 20 is provided for easy operation.

[0085] The temperature and humidity sensor is arranged at the center of the fermentation chamber and away from the steel frame 1.

[0086] An exhaust pipe 21 is further connected to the explosion-proof heater 7. One end of the exhaust pipe 21 away from the explosion-proof heater 7 is connected to the heat conduction oil tank 4, and an air valve is arranged on the exhaust pipe 21.

[0087] The air valve is a manual valve. When exhausting air, the air valve needs to be opened first to exhaust air. Before the equipment is heated, the air valve needs to be closed to work. Otherwise, the oil pressure will be too low. Thus, the heat conduction oil tank 4 has the functions of refueling and exhausting air.

[0088] It further includes an alarm 22, which is arranged on the door of the distribution box 12. One end of the alarm 22 is connected to the controller, and the other end is connected to the power supply switch.

[0089] In this embodiment, the temperature and humidity sensor is hoisted at the center of the fermentation chamber. Such a setting is to ensure that the measured data is more accurate. Setting it at the center is to ensure that the measured temperature and humidity are closer to the average temperature and humidity in the fermentation chamber. And being away from the steel frame 1 is to avoid the influence of the air near the air outlet or the humidifying port 14 on the detection of temperature and humidity.

[0090] A heat conduction oil pipe 5 is further connected to the explosion-proof heater 7 and is connected to the heat conduction oil tank 4, so that after work, the oil can return to the heat conduction oil tank 4.

[0091] Working principle: When heating, the explosion-proof heater 7 converts electrical energy into heat energy to heat the heat-conducting oil. The heat-conducting oil pump 6 works, and the heat-conducting oil circulates between the heat-conducting oil pump 6 → explosion-proof heater 7 → heat exchanger 8 → heat-conducting oil pump 6 through the heat-conducting oil pipe 5. After the heat-conducting oil is heated to the target temperature, the explosion-proof heater 7 stops working, and continues to circulate and work after the heat-conducting oil is lower than the target temperature. (There are oil temperature, flow rate, and oil pressure sensors on the pipeline to monitor the working conditions of the heat-conducting oil.)

[0092] At the same time, the circulation fan 9 works. The air inlet 17 sucks in the air in the fermentation chamber and enters the heat exchanger 8 through the air inlet pipe. The air exchanges heat at the heat exchanger 8 and blows the hot air into the fermentation chamber from the air outlet 19 on the air outlet pipe 18. At the same time, a temperature sensor is provided at the air outlet 19 to control the upper limit temperature of the hot air. The indoor temperature is monitored through the temperature and humidity sensor at the center of the fermentation chamber. Based on the information of these two sensors, the temperature intelligent control system automatically controls the explosion-proof heater 7 to stabilize the temperature of the heat-conducting oil. The hot air temperature is proportional to the heat-conducting oil temperature.

[0093] Among them, for the principle of the heat-conducting oil, the heat is generated and transmitted by the electric heating element immersed in the heat-conducting oil. Taking the heat-conducting oil as the medium and using the heat-conducting oil pump 6, the heat-conducting oil is forced to conduct liquid-phase circulation, and the heat is transferred to the heat exchanger 8. After being unloaded by the heat exchanger 8, it returns to the explosion-proof heater 7 through the heat-conducting oil pump 6 again, absorbs heat again, and transfers it to the heat-using equipment. In this way, the continuous transfer of heat is realized, the temperature of the heated object is increased, and the heating process requirements are met.

[0094] When humidifying, the humidifying water tank 2 stabilizes the water level to the working water level automatically through the float valve through the external water inlet. Through ultrasonic atomization, a large amount of atomized water is generated in the humidifying water tank 2. The humidifying fan presses the atomized water in the humidifying water tank 2 to the humidifying port 14 through the humidifying pipeline 3. The atomized water exits through the humidifying port 14 to the processing workshop. The indoor humidity is monitored through the temperature and humidity sensor at the center of the fermentation chamber (drying room), and the intelligent control system automatically and stably controls the humidity.

[0095] Among them, the principle of ultrasonic atomization humidification

[0096] The principle of ultrasonic atomization humidification is that the atomizer module at the bottom of the water tank converts electrical energy into mechanical energy, adopts electronic ultra-high-frequency oscillation, and through the high-frequency resonance of the atomizing sheet, atomized water is generated, so as to achieve the purpose of humidifying the air with equal enthalpy.

[0097] Specifically, the equipment parameters in this embodiment are as follows:

[0098]

[0099] The equipment is preferably used in places with an ambient temperature of 10°C to 40°C, a relative humidity of 40% to 85% (no condensation), and an altitude below 2000M.

[0100] As Figure 3 shown: A control method for an integrated piling fermentation and drying multifunctional machine, characterized by comprising the following steps:

[0101] I. Detect the current temperature and humidity data in the fermentation chamber through temperature and humidity sensors;

[0102] II. Set the target temperature and humidity parameters in the fermentation chamber respectively according to the temperature and humidity processing environments required for the piling fermentation of tea leaves, the fermentation of tea leaves, and the drying of tea cakes;

[0103] III. Compare the target temperature and humidity parameters in step II with the current temperature and humidity data in step I. If the current temperature and humidity data do not meet the target temperature and humidity parameters, continue the regulation through step IV. If the current temperature and humidity data are higher than the target temperature and humidity parameters, conduct the regulation through step V;

[0104] IV. Start the humidification component and the heating component to regulate the temperature and humidity in the fermentation chamber

[0105] 4.1) Turn on the ultrasonic atomizer. The ultrasonic atomizer atomizes the water in the humidification water tank, and the humidification fan inputs the atomized water into the fermentation chamber through the humidification pipeline, while ensuring that there is enough water in the humidification water tank;

[0106] 4.2) Sequentially turn on the explosion-proof heater, heat exchanger, heat conduction oil pump, and circulation fan, so that the heat conduction oil circulates sequentially between the heat conduction oil pump, explosion-proof heater, heat exchanger, and heat conduction oil pump through the heat conduction oil pipeline. The circulation fan sucks the air in the fermentation chamber to the heat exchanger for heat exchange, and then conveys the heat-exchanged air back to the fermentation chamber;

[0107] 4.3) When the temperature and humidity sensors detect that the temperature and humidity data in the fermentation chamber reach the target temperature and humidity parameters, stop the temperature and humidity regulation in step 4.1) and step 4.2);

[0108] V. Start the dehumidification fan to discharge the air in the tea leaf space out of the fermentation chamber. When the temperature and humidity sensors measure that the temperature and humidity data in the fermentation chamber are the same as the target temperature and humidity parameters, turn off the dehumidification fan.

[0109] In this embodiment, the environment for the piling fermentation of tea leaves is adjusted in the above manner, and the environment in the fermentation chamber is adjusted to: a temperature of 40 - 45 °C and a humidity of 70 - 90%, so that the leaf temperature is 53 - 54.9 °C and the ventilation is controlled (ventilation for 5 - 10 minutes every 1 hour).

[0110] Specifically:

[0111] Startup steps: Control loop power on → Touch screen power on → System login → Operation settings → Piling fermentation mode → Manual mode (Automatic mode)
