Description

Technical Field

[0001] This utility model relates to the field of tea processing technology, and more specifically to a tea rolling machine. Background Technology

[0002] The rolling machine is one of the key pieces of equipment in tea processing. It is mainly used to curl tea leaves into strips, simultaneously breaking down the tea's cell structure and causing the tea juice to seep out, laying the foundation for subsequent fermentation and drying processes. Rolling is an indispensable step in tea production, its main functions including shaping the tea leaves, improving their internal quality, and enhancing their brewing endurance. In actual operation, the rolling machine mechanically simulates traditional hand rolling, offering simple operation and high efficiency, effectively freeing up labor and increasing production efficiency. It mainly consists of a rolling drum, rolling discs, a pressure device, and a transmission mechanism. During the rolling process, the tea leaves are subjected to pressure and friction within the rolling drum, gradually curling into strips while simultaneously breaking down cells, causing tea juice to seep out and adhere to the surface of the tea leaves. After drying, this allows the tea to release its color and flavor when brewed.

[0003] While existing tea rolling machines have improved the efficiency and quality of tea processing to some extent, the uncontrollable temperature of these machines also brings many problems. First, it severely impacts tea quality. During green tea rolling, high temperatures easily reactivate polyphenol oxidase, causing browning and loss of the characteristic clear green color, reducing the freshness of the tea soup. For fermented teas such as black tea and oolong tea, high-temperature rolling easily leads to over-fermentation, making it difficult to develop the ideal flavor, such as the golden rings in black tea and the floral and fruity aromas in oolong. Simultaneously, high temperatures soften the tea leaves and cause the tea juice to clump together, resulting in loose leaves, increased broken tea, and a lower proportion of high-grade finished tea. Second, production efficiency and costs are also significantly affected. To prevent excessive temperature rise, the production process requires frequent shutdowns for cooling, interrupting continuous production and reducing efficiency. High temperatures soften the leaves, increasing the breakage rate during rolling and causing raw material waste; the sticky tea stains also significantly increase cleaning difficulty and costs. Finally, poor process stability hinders standardized production. Temperature fluctuations make the rolling effect highly dependent on environmental conditions and human experience, making it difficult to accurately replicate process parameters. The significant differences in quality between different batches of tea severely restrict the stability of product quality and the achievement of large-scale, standardized production goals.

[0004] Therefore, in response to the existing problems, how to provide a tea kneading machine that can accurately control the temperature of the kneading disc and kneading drum to avoid the problems of tea quality decline, reduced production efficiency and unstable process caused by high temperature, and at the same time, achieve efficient kneading, precise pressure and orderly discharge of tea by means of drive, pressurization and discharge components, so as to ensure kneading effect and production continuity, is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] Therefore, this utility model provides a tea kneading machine that can precisely control the temperature of the kneading disc and the kneading drum, avoiding problems such as decreased tea quality, reduced production efficiency, and unstable process caused by high temperature. At the same time, with the help of drive, pressurization, and discharge components, it can achieve efficient kneading, precise pressurization, and orderly discharge of tea, ensuring the kneading effect and production continuity.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

One end of each set of coils is connected to the water inlet of the temperature control component, and the other end is connected to the water outlet of the temperature control component, so as to control the temperature of the kneading disc and the kneading drum.

[0011] Through the above technical solution, this utility model provides a tea rolling machine that achieves precise temperature control during the tea rolling process through the synergistic action of the frame, rolling disc, rolling drum, and temperature control components. The arc-shaped ribs on the rolling disc improve rolling efficiency, the discharge port design facilitates the discharge of tea leaves after rolling, and the cavities inside the rolling disc and rolling drum, combined with the temperature control components, realize the temperature regulation function, thereby improving the rolling effect and production efficiency.

[0021] The beneficial effects of this invention are: the design of the discharge channel enables the kneading machine to efficiently discharge the kneaded tea leaves.

One end of the connecting rod 13 is hinged to the first frame 11, and the other end is hinged to the second frame 12. The mounting end of the rotary motor 61 is fixed to the first frame 11. The pulley 62 is rotatably connected to the second frame 12. The belt 63 is wound around the rotating end of the rotary motor 61 and the pulley 62 respectively, so that the rotary motor 61 can drive the rotation of the second frame 12.

[0045] To further optimize the above technical solution, a pressure cover assembly 7 is also included. The pressure cover assembly 7 includes a support member 71 and a pressure cover 72. One end of the support member 71 is vertically fixed on the second frame 12. The pressure cover 72 is fixed on the other end of the support member 71 and is located above the kneading drum 3.

[0046] To further optimize the above technical solution, the support component 71 includes a sliding column 711, a lead screw, a nut, and a cross arm 712.

The nut is threaded onto the lead screw. One end of the cross arm 712 is sleeved on the outer wall of the sliding column 711 and connected to the nut, while the other end is fixedly connected to a pressure cap 72.

[0047] To further optimize the above technical solution, the kneading disc 2 also includes a baffle 22, which corresponds to the discharge port, with one end hinged to the lower wall of the kneading disc 2 and the other end detachably connected to the lower wall of the kneading disc 2.

[0048] To further optimize the above technical solution, a discharge channel 8 is also included. The discharge channel 8 is arranged at an angle, and one end of it is fixed to the bottom wall of the kneading disc 2 corresponding to the discharge port.

[0049] To further optimize the above technical solution, the temperature control box 4 includes a water tank 41, a water pipe 42, a refrigeration system 43, and a heating system 44. One end of the water pipe 42 is connected to the water tank 41, and the other end is connected to two sets of coils 5. Both the refrigeration system 43 and the heating system 44 are connected to the water pipe 42 to achieve temperature control of the water. See the appendix for details. Figure 6 .

[0050] In one embodiment, the refrigeration system 43 includes a compressor 431, an evaporator 432, a solenoid valve 433, an expansion valve 434, a condenser 435, a sight glass 436, a filter cartridge 437, a filter cartridge support 438, an angle valve 439, a control system 4310, a pressure switch, and a flow switch. Specifically, the compressor 431 draws in low-temperature, low-pressure gas from the evaporator 432, compresses it into high-temperature, high-pressure gas, and then discharges it. The high-temperature, high-pressure gas passes through the filter cartridge 437 to filter impurities and then enters the condenser 435. In the condenser 435, the high-temperature, high-pressure gas releases heat and condenses into a high-pressure liquid. The high-pressure liquid flows to the expansion valve 434 after its flow rate is regulated by the angle valve 439. The expansion valve 434 depressurizes the high-pressure liquid, making it a low-temperature, low-pressure gas-liquid mixture. This low-temperature, low-pressure gas-liquid mixture enters the evaporator 432, where it absorbs heat and evaporates into a low-temperature, low-pressure gas. Finally, the low-temperature, low-pressure gas flows out of the evaporator 432 and returns to the compressor 431, completing the entire refrigeration cycle. Simultaneously, the solenoid valve 433 and angle valve 439 control the refrigerant flow, while the pressure switch and flow switch monitor system pressure and flow, providing feedback to the control system to ensure stable operation of the refrigeration system. A sight glass is used to observe the refrigerant flow, and the filter cartridge 437 and its support 438 filter impurities, protecting the system. The entire system achieves a highly efficient refrigeration cycle through the interaction of these components. See appendix for details. Figure 7 .

[0051] Specifically, the heating system 44 is an electric heating tape, and the outer wall of the electric heating tape is also covered with heat insulation cotton.

[0052] More specifically, the inner walls of the kneading disc 2 and the kneading cylinder 3 are respectively equipped with a first temperature sensor and a second temperature sensor.

[0053] In a specific embodiment, based on feedback from the first temperature sensor 24 and the second temperature sensor 32, when cooling is required, the water in the tank flows through the refrigeration system into the coil 5; when heating is required, the water in the tank flows through the heating system into the coil 5.

[0054] In one specific embodiment, the temperature control box 4 further includes a circulation system 45, which includes a circulation pump 451 and an overflow valve 452. The circulation pump 451 is connected to the water pipe 42, and the overflow valve 453 is also connected in series to the water pipe 42. Meanwhile, a first electric ball valve 46, a second electric ball valve 47, and a third electric ball valve 48 are also installed on the water pipe to ensure normal operation between cold and hot water.

[0055] The method of use and working principle of this utility model are as follows:

[0056] After the tea leaves have been processed (killed), they are evenly placed into the kneading drum 3, ensuring uniform distribution. Based on the age and tenderness of the tea leaves and the requirements of the kneading process, the temperature of the kneading disc 2 and the kneading drum 3 is adjusted to a suitable range using a temperature control component. The height and pressure of the pressure cap component 7 are adjusted to ensure it contacts the tea leaves in the kneading drum 2 and applies appropriate pressure. Then, the rotary motor 61 is started, driving the kneading drum 3 to rotate. During rotation, the tea leaves inside the kneading drum 3 are squeezed and rubbed by the arc-shaped ribs 23 on the kneading disc 2, gradually curling into strips. The cavities inside the kneading disc 2 and the kneading drum 3 are connected to the temperature control box 4 via a coil 5. The temperature control box 4 supplies hot or cold water to the coil 5 through a water pipe, achieving precise temperature control of the kneading disc 2 and the kneading drum 3, avoiding adverse effects of high temperatures on tea quality. The pressure cap component 7 applies uniform pressure to the tea leaves in the kneading drum 3, ensuring even force distribution during kneading and preventing insufficient or excessive kneading. After kneading, the baffle on the kneading disc 2 is opened, and the kneaded tea leaves enter the inclined discharge channel 8 through the discharge port in the center of the kneading disc 2, smoothly exiting the kneading machine. The design of the discharge channel 8 optimizes the smoothness of discharge, reduces tea residue in the kneading machine, and improves the cleanliness and production efficiency of the equipment. The temperature control components include a water tank, water pipes, a refrigeration system, and a heating system. The temperature of the water in the water pipes is regulated by the refrigeration and heating systems to achieve temperature control of the kneading disc 2 and the kneading cylinder 3. This design ensures that the kneading machine can maintain a suitable kneading temperature in different seasons and environments, adapting to the processing needs of different types of tea, while improving the consistency of kneading results.
