Description

Technical Field

[0001] This invention relates to the field of berry tea production technology, specifically to an integrated machine for fermenting, drying, and enhancing the aroma of berry tea, as well as a berry tea production process and control method. Background Technology

[0002] Berry tea, also known as small-leaf vine tea, is made from a plant that contains the natural active ingredient flavonoids. It has the highest flavonoid content of all discovered plants and is known as the "King of Flavonoids". Because the cells are broken during the processing, the active flavonoids contained in the cells penetrate to the surface and form a layer of white microcrystals, hence the name "berry tea".

[0003] After being re-rolled, the berry tea undergoes a series of fermentation processes: piling, drying, and aroma enhancement. Piling involves packing the loosened berry tea leaves into frames for fermentation until light white spots appear on the surface of the leaves, indicating that piling is complete. Drying is done using a rotary dryer at 100℃, where the fermented berry tea leaves are placed in layers and dried until the dryness is ≤95%. Aroma enhancement involves pouring the dried berry tea leaves into an aroma enhancement machine to enhance their fragrance.

[0004] It can be seen that in the existing berry tea production process, the fermentation, drying and aroma enhancement of berry tea are completed in different places. The berry tea needs to be transferred between processes. The transfer process can easily lead to the loss of white microcrystals and aroma, affecting the quality of the berry tea produced.

[0035] Compared with the prior art, the integrated machine for fermenting, drying and enhancing aroma of berry tea, the berry tea making process and control method provided by the present invention have the following beneficial effects:

[0036] (1) When the berry tea fermentation, drying and aroma enhancement integrated machine is used for berry tea production, the heat generated by the first air compressor and the second air compressor can regulate the temperature of the processing room. The oxygen generation device and the atomizing device can regulate the oxygen and humidity of the processing room respectively. The condensing device can condense the air in the processing room and discharge the condensate to the outside of the processing room to achieve the dehumidification effect.

[0045] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0046] In the existing berry tea production process, the fermentation, drying, and aroma enhancement of berry tea are completed in different places. The berry tea needs to be transferred between processes, which can easily lead to the loss of white microcrystals and aroma, affecting the quality of the berry tea.

[0047] To address the aforementioned technical problems, this embodiment provides an integrated machine for fermenting, drying, and enhancing the aroma of berry tea. Please refer to [link / reference]. Figure 1 and Figure 2 As shown, Figure 1 This is a schematic diagram of the integrated fermentation, drying, and aroma-enhancing machine for berry tea, as shown in the embodiment. Figure 2 This is a structural block diagram of the integrated machine for fermenting, drying, and enhancing the aroma of berry tea, as shown in the embodiment.

[0048] The integrated machine for fermenting, drying, and enhancing the aroma of berry tea in this embodiment includes: a processing chamber 1, a heating device 2, a condensing device 3, a first air compressor 4, a second air compressor 5, an oxygen generating device 6, and an atomizing device 7.

[0049] The processing chamber 1 is provided with an internal space 11 for placing raw materials, an airflow channel 12 connected to the internal space 11, and a dehumidification port 13 and an air inlet 14 connected to the internal space 11 and capable of being opened and closed.

[0050] The aforementioned processing chamber 1 can be a warehouse made of polyurethane sandwich panels. The internal space 11 can be used to place raw materials through shelves 18. The airflow channel 12 is used for airflow circulation inside the processing chamber 1, allowing the airflow in the internal space 11 to circulate through the airflow channel 12. The exhaust port 13 is used to discharge the airflow with high humidity inside the processing chamber 1, reducing the internal humidity. The air inlet 14 is used to introduce external airflow. The upper air inlet 14 and the exhaust port 13 can be opened and closed through a door panel, which can be an automatic door and controlled by the control module 9.

[0051] The heating device 2 is located inside the airflow channel 12.

[0052] The heating device 2 mentioned above is used to increase the internal temperature of the processing chamber 1, and can be an electric heating device 2 installed inside the processing chamber 1.

[0053] The condenser 3 is located in the airflow channel 12 and is configured to condense the air in the treatment chamber 1 and discharge the condensate to the outside of the treatment chamber 1.

[0054] The aforementioned condensing device 3 can be a condensing pipe or condensing plate installed inside the airflow channel 12. The hot air in the airflow channel 12 condenses into water upon contact with the condensing device 3, thereby achieving the effect of dehumidification.

[0055] The first air compressor 4 is located inside the processing chamber 1.

[0056] The first air compressor 4 can be placed at the bottom of the processing chamber 1 to compress the gas in the processing chamber 1 and discharge it, increase the gas flow speed in the processing chamber 1, and transfer the heat generated by the compressed gas to the interior of the processing chamber 1, thereby increasing the temperature inside the processing chamber 1 and improving the tea drying efficiency.

[0057] The second air compressor 5 is located outside the processing chamber 1 and is equipped with a guide fan 8. The guide fan 8 is used to dissipate heat from the second air compressor 5 and discharge the heat into the processing chamber 1 through the air inlet 14.

[0058] The aforementioned second air compressor 5 can be installed inside the casing, which can be fixed to the outside of the processing chamber 1. The second air compressor 5 is used to compress the gas outside the processing chamber 1 and discharge the compressed gas to the outside of the processing chamber 1. The heat generated by the compressed gas is transported to the inside of the processing chamber 1 through the guide fan 8. The guide fan 8 can be installed outside the processing chamber 1, with its air intake side facing the second air compressor 5 and its air exhaust side facing the air inlet 14 of the processing chamber 1. When the air inlet 14 is open, it can discharge hot air into the processing chamber 1. When the air inlet 14 is closed, it can blow the hot air to the outside of the casing.

[0059] The oxygen generating device 6 is connected to the second air compressor 5 via a pipeline, and the oxygen generating device 6 discharges oxygen into the processing chamber 1 when it is in operation.

[0060] The aforementioned oxygen generator 6 is used to extract pure oxygen from the air. Its working principle can be based on molecular sieve adsorption (PSA) technology or condensation separation technology. When based on PSA technology, compressed air from the second air compressor 5 enters the adsorption tower of the oxygen generator 6. The adsorption tower is filled with molecular sieve adsorbent, which selectively adsorbs impurity gases such as nitrogen, leaving oxygen in an unadsorbed state. When compressed air passes through the adsorption tower, impurity gases are adsorbed onto the molecular sieve, while pure oxygen flows out through the tower. When the adsorption tower is saturated, it needs to be regenerated, and the oxygen generator will stop supplying compressed air. The oxygen generator should release most of the compressed air to expel the adsorbed gas from the adsorbent. After that, the oxygen generator switches to another adsorption tower to ensure the continuous production of pure oxygen. When based on condensation separation technology, the oxygen generator 6 first pressurizes the air through the second air compressor 5 to increase its temperature and pressure. Then, the compressed air is cooled by the cooler, and due to the reduced temperature, the water vapor in it condenses into liquid water, which is then separated and removed. The cooled air enters the separator, where impurity gases such as nitrogen are separated through a membrane or other separation device, while the pure oxygen is collected and transported to the interior of the processing chamber 1.

[0061] The atomizing device 7 is configured to deliver atomized liquid to the processing chamber 1.

[0062] The aforementioned atomizing device 7 is used to increase the humidity in the processing chamber 1. It can be a compression atomizer and is supplied with compressed air through the second air compressor 5.

[0063] It is understandable that the integrated machine for fermenting, drying and enhancing the aroma of berry tea also includes a control module 9 for controlling the heating device 2, the condensing device 3, the first air compressor 4, the second air compressor 5, the oxygen generating device 6 and the atomizing device 7. The control module 9 is electrically connected to the above-mentioned components.

[0064] When the above-mentioned integrated machine for fermenting, drying, and enhancing the aroma of berry tea is used for the production process, the heat generated by the first air compressor 4 and the second air compressor 5 can regulate the temperature inside the processing chamber 1. The oxygen generating device 6 and the atomizing device 7 can respectively regulate the oxygen content and humidity inside the processing chamber 1. The condensing device 3 can condense the air inside the processing chamber 1 and discharge the condensate to the outside of the processing chamber 1 to achieve a dehumidification effect. The fermentation, drying, and aroma enhancement of berry tea can all be completed inside the processing chamber 1. There is no need to transfer berry tea between processes, which reduces the loss of white microcrystals and aroma and improves the quality of berry tea.

[0065] Meanwhile, the first air compressor 4 and the second air compressor 5 of the above-mentioned integrated machine for fermenting, drying and enhancing aroma of berry tea are respectively located inside and outside the processing chamber 1 and work together. They can work simultaneously during fermentation, room temperature drying and low temperature drying to improve the heat conversion rate. They can also shut down the first air compressor 4 during high temperature aroma enhancement to protect the first air compressor 4 from high temperature. The second air compressor 5 and the heating device 2 work together to achieve the temperature required for high temperature aroma enhancement.

[0066] Last but not least, the second air compressor 5 of the above-mentioned integrated machine for fermenting, drying and enhancing the aroma of mulberry tea has multiple functions. It can be used as a temperature regulating component of the processing chamber 1; it can also be used as an air compression component of the oxygen generating device 6, delivering compressed air through pipelines to the oxygen generating device 6 to achieve the oxygen generating function; and it can also be used as an airflow acceleration component of the atomizing device 7, delivering compressed air to the atomizing device 7 to atomize water through high-speed airflow.

[0067] In one embodiment of the above-mentioned processing chamber 1, the airflow channel 12 of the processing chamber 1 includes a transverse section 121 and a longitudinal section 122. The transverse section 121 is located at the top of the processing chamber 1, and the longitudinal section 122 extends from the transverse section 121 along the inner side of the processing chamber 1 to the bottom of the processing chamber 1. The exhaust port 13 is located at the connection between the transverse section 121 and the internal space 11. The condensing device 3 is located in the longitudinal section 122, and the heating device 2 is located at the connection between the transverse section 121 and the longitudinal section 122. The air inlet 14 is located at the bottom of the longitudinal section 122, and the longitudinal section 122 is provided with an air supply channel 123 communicating with the internal space 11 at the position opposite to the air inlet 14. The first air compressor 4 is located between the air inlet 14 and the air supply channel 123. With this setup, during the fermentation, drying, and low-temperature drying of the berry tea, the cooling fan can transport the heat from the first air compressor 4 and the second air compressor 5 to the internal space 11 through the air supply channel 123 to heat the berry tea. Then, the heat enters the airflow channel 12 for circulation. The condensing device 3 and the heating device 2 in the airflow channel 12 improve the condensation and heating efficiency of the airflow in the processing chamber 1. At the same time, during the drying process, the moisture is directly discharged from the internal space 11 to the exhaust port 13. Overall, the above setup can improve the heating speed, circulation efficiency, and dehumidification efficiency of the processing chamber 1.

[0068] In order to automatically monitor the temperature, humidity and oxygen content in the processing chamber 1, the processing chamber 1 is equipped with a temperature sensor 15, a humidity sensor 16 and an oxygen content sensor 17. The temperature sensor 15, humidity sensor 16 and oxygen content sensor 17 are electrically connected to the control module 9 and are used to feed back the temperature information, humidity information and oxygen content information to the control module 9. The control module 9 sends control commands to each component according to the corresponding information.

[0069] In order to improve the condensation efficiency of the condensing device 3, the condensing device 3 is equipped with a condensing fan 30. The condensing fan 30 is configured to blow the gas in the internal space 11 toward the condensing device 3. The condensing fan 30 can be installed on the airflow channel 12, with the side that draws in the airflow facing the internal space 11 and the side that blows out the airflow facing the condensing device 3.

[0070] In one embodiment of the atomizing device 7, the atomizing device 7 is a compression atomizing device 7, and is connected to the compressed air output end of the second air compressor 5 through a pipeline. The pipeline is equipped with a valve, such as a solenoid valve. In this case, the atomizing device 7 and the oxygen generating device 6 can be connected in parallel to the second air compressor 5. The liquid in the atomizing device 7 is pumped from the storage tank and transported to the nozzle through the pipeline. The second air compressor 5 provides compressed air, which is transported to the nozzle through the pipeline to produce an atomization effect. At the nozzle, the liquid and compressed air meet and mix. The high-speed flow of the compressed air disperses the liquid into a mist of small particles. The atomized liquid forms small droplets, which are then sprayed out from the nozzle.

[0071] This embodiment provides a process for making berry tea, using the aforementioned integrated berry tea fermentation, drying, and aroma-enhancing machine, including the following steps:

[0072] S1: Fermentation: The first air compressor 4, the second air compressor 5, the oxygen generator 6 and the atomizing device 7 are working, the vent 13 is closed, and the raw material is in the treatment chamber 1 at a temperature of 40-50℃, a humidity of 90%-96% and an oxygen content of 95-96% for 1.5-2 hours until white microcrystals are visible on the surface of the raw material.

Then, the temperature in the treatment chamber 1 is 63-67℃, and the moisture content is dried to 18%-22%. Finally, the temperature in the treatment chamber 1 is 73-77℃, and the moisture content is dried to 9%-10%.

[0075] S4: Aroma Enhancement and Drying: Air compressor No. 1 stops, air inlet 14 is closed, air compressor No. 2 and heating device 2 operate, the temperature in processing chamber 1 is 115-125℃, and it lasts for 5-8 minutes.

[0076] Understandably, the fermentation process can also include steps such as harvesting, withering, blanching, and rolling.

[0077] In some embodiments, in step S1, the humidity of the treatment chamber 1 during fermentation is 90% and the oxygen content is 96%; in step S3, during low-temperature drying, the temperature inside the treatment chamber 1 is 40°C, and the drying is carried out to a moisture content of 40%; subsequently, the temperature inside the treatment chamber 1 is 65°C, and the drying is carried out to a moisture content of 20%; finally, the temperature inside the treatment chamber 1 is 75°C, and the drying is carried out to a moisture content of 10%; in step S4, the temperature of the treatment chamber 1 during aroma extraction drying is 120°C.

[0078] The above technical solution for berry tea production includes fermentation, room temperature drying, low temperature drying, and high temperature aroma enhancement. During fermentation, humidity and oxygen content are strictly controlled. The berry tea is dried at room temperature for 2-3 hours. During low temperature drying, the berry tea is dried in stages to the preset moisture content through a temperature gradient. The aroma is then enhanced quickly and at high temperature. All of the above steps are completed in processing chamber 1. As a result, the white microcrystals in the berry tea are clearly precipitated and do not easily fall off, improving the appearance and quality, and giving it a rich aroma.

[0079] This invention also provides a control method for an integrated machine for fermenting, drying, and enhancing the aroma of berry tea, applied to the aforementioned integrated machine, comprising the following steps:

[0080] The control module 9 sends corresponding control signals to the heating device 2, condensing device 3, first air compressor 4, second air compressor 5, oxygen generator 6, and atomizing device 7 based on the temperature data, humidity data, and oxygen concentration data collected by the temperature sensor 15, humidity sensor 16, and oxygen content sensor 17. The control signals are configured so that the heating device 2, condensing device 3, first air compressor 4, second air compressor 5, oxygen generator 6, and atomizing device 7 perform corresponding operations according to the control signals.

[0081] In some implementation schemes, the control method for the integrated fermentation, drying, and aroma-enhancing machine for berry tea includes the following steps:

[0082] S10: Control module 9 controls the operation of the first air compressor 4, the second air compressor 5, the oxygen generator 6 and the atomizing device 7 to maintain the temperature of the treatment chamber 1 at 40-50℃, humidity at 90% and oxygen content at 96% for 1.5-2 hours.

[0083] S20: Control module 9 controls the operation of the first air compressor 4, the second air compressor 5 and the condenser fan 30 for 2-3 hours.

[0084] S30: Control module 9 controls the first air compressor 4 and the second air compressor 5 to operate, so that the temperature in the processing chamber 1 is maintained at 40℃, 65℃ and 75℃ for a period of time in sequence.

[0085] S40: Control module 9 controls air compressor 1 to stop, and controls air compressor 2 and heating device 2 to operate, so that the temperature in processing chamber 1 is 120℃ for 5-8 minutes.

[0086] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
