Description

Technical Field

[0001] The invention belongs to the technical field of tea wine production, and particularly relates to a tea wine production process and raw material soaking equipment for brewing the same. Background Art

[0002] Tea wine is a specialty beverage that blends the fragrance of tea with the richness of wine. It combines the natural flavor of tea with the unique taste of wine and is deeply loved by consumers. In the tea wine brewing process, soaking the raw materials is a crucial step. The core of this process is to place the tea leaves and other raw materials in the wine base. After a certain period of soaking, the effective ingredients in the tea, such as tea polyphenols, amino acids, and aroma compounds, are fully dissolved into the base, laying the foundation for the subsequent brewing of harmonious flavor and high-quality tea wine.

[0003] At present, tea leaves are mostly cleaned manually before soaking tea wine raw materials, which is inefficient and uneven in cleanliness, making it difficult to achieve continuous processing. Soaking relies on static soaking in containers, and the tea leaves tend to accumulate at the bottom of the container during the soaking process, resulting in insufficient solid-liquid contact and low dissolution rate of effective ingredients. At the same time, the wastewater generated by washing the tea leaves is directly discharged and cannot be reused, which does not meet the requirements of energy conservation and environmental protection.

[0050] like Figure 3 andFigure 8 As shown, the soaking tank 1 is provided with a cleaning pipe group 7, which includes an inlet pipe 71 and a drain pipe 72. The inlet pipe 71 and the drain pipe 72 are fixedly arranged on the soaking tank 1. A control valve is provided between the inlet pipe 71, the drain pipe 72 and the soaking tank 1. An annular pipe 73 is fixedly provided at one end of the water inlet pipe 71. A nozzle 731 is arranged in an array on the annular pipe 73. The annular pipe 73 is located below the annular screen 6, so that the high-pressure water flow stirs the tea leaves from below, thereby improving the cleaning efficiency. The soaking tank 1 is connected to the constant temperature tank 9 through the cleaning pipe group 7. The constant temperature tank 9 is integrated with a temperature control device. The temperature control device is a prior art, including a heating plate and a temperature sensor, etc., so as to adjust the temperature of the water source in the constant temperature tank 9. The constant temperature tank 9 is provided with a filter screen 91. The filter screen 9 1 is provided with an adsorption layer for further purification, the water inlet pipe 71 and the drain pipe 72 are both connected to the thermostatic tank 9, one end of the water inlet pipe 71 is located below the filter screen 91, and one end of the drain pipe 72 is located above the filter screen 91. A water pump is provided between the water inlet pipe 71 and the thermostatic tank 9, and the water source in the thermostatic tank 9 is extracted by the water pump. The water inlet pipe 71 and the drain pipe 72 of the cleaning pipe group 7 realize the recycling of cleaning water and save water resources; the control valve can flexibly control the water flow and is convenient for operation; the nozzles 731 on the annular pipe 73 are distributed in an array, which can rinse the tea leaves on the annular screen 6 in all directions to ensure the cleaning effect; the thermostatic tank 9 can maintain a stable water temperature, and the filter screen 91 can filter and purify the returned sewage to ensure the cleanliness of the water used again and improve the cleaning quality of the raw materials.

[0051] like Figure 3 and Figure 4 As shown, a temperature control pipe group 8 is provided in the hollow shaft 5, and the temperature control pipe group 8 includes an inlet pipe 2 81 and a drain pipe 2 82. The inlet pipe 2 81 and the drain pipe 2 82 extend into the hollow shaft 5 through the opening at the lower end of the hollow shaft 5, and the inlet pipe 2 81 is connected and communicated with the drain pipe 2 82.

[0052] A tea wine production process, the process flow is as follows:

[0053] S1: Select organic tea and organic liquor that are both medicinal and edible, conduct acceptance inspections, and ensure the quality and safety of the raw materials from the source. Organic tea that is both medicinal and edible not only gives the tea and liquor a unique flavor but also has certain health benefits. Organic liquor ensures the purity of the base liquor, laying the foundation for the subsequent brewing of high-quality tea and liquor.

[0054] S2: The screened tea leaves are placed between the soaking tank 1 and the inner tank 11 through the feed port 10, and fall onto the annular screen 6. The tea leaves on the annular screen 6 are rinsed through the water inlet pipe 1 71 and the annular pipe 73. The tea leaves are placed through the feed port 10, and the annular screen 6 receives them. The tea leaves are then rinsed through the water inlet pipe 1 71 and the annular pipe 73, which can effectively remove impurities and dust on the surface of the tea leaves, thereby improving the cleanliness of the raw materials. The rinsing process is highly automated, saving manpower.

[0055] S3: The washed tea leaves are lifted and drained through the annular sieve 6. When the annular sieve 6 rises to the highest point, it slides down through its slope into the inner tank 11 and falls onto the movable sieve 41. The lifting function of the annular sieve 6 realizes the automatic transfer of the washed tea leaves. The drainage process reduces the amount of excess water entering the inner tank 11, avoiding affecting the concentration of the wine. The inclined surface design uses gravity to make the tea leaves slide automatically into the inner tank 11, without the need for additional power, energy-saving and efficient. The movable sieve 41 receives the tea leaves and prepares them for subsequent soaking.

[0056] S4: The organic wine that has been inspected and accepted is poured into the inner tank 11 in proportion through the liquid inlet pipe 14 to soak the tea leaves. During this period, the movable screen 41 is shaken up and down by rotating the hollow shaft 5 1 to 2 times a day, and the circulating pump 2 is used for circulation and stirring. Each time lasts for 10 to 20 minutes. The hollow shaft 5 drives the movable screen 41 to shake up and down to ensure that the tea leaves are fully in contact with the wine. The circulation stirring of the circulating pump 2 further promotes the fusion of the ingredients. Regular operation every day ensures uniform soaking and improves the quality of the tea wine.

[0057] S5: Connecting the second water inlet pipe 81 and the second drain pipe 82 to the constant temperature tank 9 through valves, so that the organic tea and organic wine in the inner tank 11 are mixed and soaked at 15°C to 30°C for 10 to 15 days. The temperature control system is activated by valve control to stabilize the soaking temperature within the appropriate range of 15°C to 30°C, which is conducive to the full dissolution of the active ingredients in the tea. The 10 to 15 days of soaking ensures that the ingredients are fully extracted, thereby enhancing the flavor and nutrition of the tea wine.

[0058] S6: The solid-liquid mixture is separated into solid and liquid by a movable screen 41, and the separated extract is input into a stainless steel storage tank for standby use, or the separated extract is input into a distillation pot for distillation, and the distilled tea wine is then transported to a stainless steel storage tank for storage;

[0059] S7: Reduce the alcohol content as required and blend;

[0060] S8: Filter the blended product and take samples for inspection after filtration;

[0061] S9: Fill the organic tea and wine products that have passed the inspection.

[0062] It should be noted that the working principle of this scheme is as follows: first, the screened tea leaves are put into the annular screen 6 between the soaking tank 1 and the inner tank 11 through the feed port 10 and the guide pipe 101, and then the cleaning pipe group 7 is started, and the water inlet pipe 1 71 transports the clean water in the constant temperature tank 9 to the annular pipe 73, and the tea leaves on the annular screen 6 are fully rinsed through the array-distributed nozzles 731. The sewage generated by the rinse falls through the sieve holes of the annular screen 6 and flows back to the constant temperature tank 9 through the drain pipe 1 72 for filtration. After the cleaning is completed, the servo motor 2 62 is started to drive the screw rod 621 to rotate, driving the threaded sleeve 61 and the annular screen 6 to slide slowly, and the tea leaves are gradually gathered under the guidance of the concave inclined surface of the annular screen 6, and the telescopic tube 63 is synchronously extended and retracted with the annular screen 6; when the annular screen 6 rises to the highest point, the tea leaves slide into the inner tank 11 along the inclined surface by their own gravity, and finally fall onto the movable screen 41 of the vibrating screen group 4, completing the cleaning and transportation of the raw materials.

[0063] Next, the immersion stage begins. Approved organic liquor is poured into the inner tank 11 in proportion through the liquid inlet pipe 14, completely submerging the tea leaves. Servo motor 1 52 is activated, and the bevel gear B521 at its output engages with the bevel gear A51 at the lower end of the hollow shaft 5, driving the hollow shaft 5 to rotate steadily. The connecting sleeve 43, fixed to the hollow shaft 5, rotates accordingly. The movable screen 41 slides within the chute 431 of the connecting sleeve 43 via the protruding rod 2 421 within the collar 42. Simultaneously, the protruding rod 1 411 on the edge of the movable screen 41 engages within the corrugated groove 44 of the inner tank 11 and slides along the groove. Under these dual effects, the movable screen 41 not only moves in a circular motion with the hollow shaft 5 but also generates a high-frequency up-and-down vibration, prompting the tea leaves to continuously flip within the inner tank 11 and prevent localized accumulation. At the same time, the circulation pump 2 is started, and the liquid at the lower end of the inner tank 11 is pumped to the upper end through the circulation pipes 21 at both ends, forming an up and down circulating liquid flow, accelerating the fusion of the components of tea and organic wine. Each cycle of stirring lasts 10 to 20 minutes, and is performed 1 to 2 times a day.

[0064] During the entire soaking process, the connection between the water inlet pipe 71 and the drain pipe 72 and the soaking tank 1 is closed through the valve, and the water inlet pipe 71 and the drain pipe 72 are connected to the water inlet pipe 2 81 and the drain pipe 2 82 respectively through the three-way valve, and the filtered clean water in the constant temperature tank 9 enters the hollow shaft 5 through the water inlet pipe 2 81. During the rotation of the hollow shaft 5, the clean water exchanges heat with the mixed liquid in the inner tank 11 through the pipe wall, and then flows back to the constant temperature tank 9 through the drain pipe 2 82. It is filtered by the filter screen 91 and then recycled, so that the temperature in the inner tank 11 is always stable at 15℃~30℃, ensuring that the effective ingredients of the tea are fully dissolved at an appropriate temperature. The entire soaking cycle lasts 10~15 days.

[0065] After the soaking is completed, the vibrating screen group 4 is started again. The rotation and shaking of the movable screen 41 separates the solid-liquid mixture. The tea residue is trapped on the movable screen 41, and the extract flows into the bottom of the inner tank 11 through the screen holes. The valve of the drain pipe 13 is opened, and the extract is transported to the stainless steel storage tank for standby. Finally, the sealing cover 3 of the sewage outlet 12 is opened, and the hollow shaft 5 is rotated by the servo motor 52 to change the angle of the movable screen 41, and the tea residue is thoroughly cleaned through the sewage outlet 12, completing a complete soaking process.

[0066] After the soaking is completed, the separated extract is input into a stainless steel storage tank for standby use, or the separated extract is input into a wine distillation pot for distillation, and after obtaining the distilled tea wine, it is transported to a stainless steel storage tank for storage for standby use.

[0067] Finally, the alcohol content is reduced as required, and the blending is carried out. The blended product is filtered, and after the filtration is completed, samples are taken for inspection, and the qualified organic products are bottled.

[0068] The above-described embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
