[0002] In the preparation of cold-brewed fresh tea beverages, fresh tea leaves are generally first subjected to cell wall breaking and pulverization, and then extracted with ice water at low temperature to obtain the extract.

[0003] In the Chinese Patent Document Database, patent application number 202421192171.4 discloses a cold extraction tank for preparing cold-extracted fresh tea beverages. It discharges the material after cold extraction by setting a slag discharge pipe at the bottom of the filter cylinder. It improves the fluidity of the liquid inside the cold extraction tank by setting a motor and bevel gear at the bottom of the filter cylinder to drive the filter cylinder to rotate, thereby improving the extraction efficiency. However, in actual process, the high-speed rotation of the filter cylinder may reduce the sealing between its outer wall and the contact surface at the bottom of the cold extraction tank, which may lead to liquid leakage, making it impractical.

[0023] Please see Figure 1-4This utility model provides an embodiment of a cold extraction tank for preparing cold-brewed fresh tea beverages, comprising an extraction tank 1, a liquid outlet 6 disposed on the outer wall of the extraction tank 1, and a filter cylinder 3 rotatably mounted at the center of the interior of the extraction tank 1 via a rotary drive mechanism 4. A top cover 2 is detachably mounted on the top of the extraction tank 1. The filter cylinder 3 is a cylindrical structure with both ends open, and filter holes are provided on its side wall. The bottom end of the filter cylinder 3 abuts against the bottom end inside the extraction tank 1, and the top end of the filter cylinder 3 extends to the outside of the top cover 2, forming two relatively independent cavities between the extraction tank 1 and the filter cylinder 3. A sealing cap 5 is detachably mounted on the filter cylinder 3 outside the top cover 2 via threads. The rotary drive mechanism 4 is mounted on the top cover 2 and is used to drive the filter cylinder 3 to rotate. In this embodiment, the rotary drive mechanism 4 includes a first gear 401 fixed on the outer wall of the filter cartridge 3, a second gear 402 disposed on one side of the first gear 401, and a motor 403 that drives the second gear 402 to rotate. The first gear 401 and the second gear 402 mesh with each other. The top of the top cover 2 is provided with a protective cover for covering the first gear 401 and the second gear 402 inside. At the same time, the protective cover is provided with an opening that is adapted to the filter cartridge 3. The motor 403 is installed on the top of the protective cover, and the output end of the motor 403 extends into the inside of the protective cover and is fixedly connected to the second gear 402. It can drive the filter cartridge 3 to rotate at the center of the extraction tank 1. During the cold extraction process, it drives the internal liquid to flow and improves the extraction efficiency.

[0024] In this embodiment, a sealing ring 101 coaxial with the filter cartridge 3 is provided at the bottom of the extraction tank 1, and the sealing ring 101 abuts against the outer wall of the filter cartridge 3 to seal, so as to prevent the material inside the filter cartridge 3 from escaping to the outside of the extraction tank 1.

[0025] In this embodiment, the extraction tank 1 has a cylindrical structure. A second cleaning component 10 for cleaning the inner circumferential wall of the extraction tank 1 is detachably installed on the outer wall of the filter cylinder 3. The second cleaning component 10 includes a clamp 1001, a connecting rod 1002 and a cleaning brush 1003 symmetrically arranged at both ends of the filter cylinder 3. The clamps 1001 are provided with mounting parts on both sides of opposite ends. The mounting parts can be fixedly connected by bolts and nuts to clamp and fix the filter cylinder 3 in the middle. The cleaning brush 1003 abuts against the inner wall of the extraction tank 1. The connecting rod 1002 is used to connect the clamp 1001 and the cleaning brush 1003. During the cold extraction process, the second cleaning component 10 is removed for greater safety and hygiene. After the cold extraction is completed, it is installed on the outer wall of the filter cylinder 3. The rotation of the filter cylinder 3 drives the second cleaning component 10 to rotate, thereby cleaning the inner wall of the extraction tank 1.

[0026] The bottom of the extraction tank 1 is fixed with three support legs 8. The middle of the bottom of the extraction tank 1 is provided with a slag discharge port 7 for discharging the material inside the filter cartridge 3. The slag discharge port 7 is located below the filter cartridge 3, which facilitates the downward discharge of the material inside after the cold extraction is completed.

[0027] A first cleaning component 9 for cleaning the filter cartridge 3 is provided at the center of the extraction tank 1. The first cleaning component 9 includes several support rods 902 vertically fixed to the bottom of the extraction tank 1 and an annular cleaning brush 901 fixed to the top of the support rods 902. The outer peripheral wall of the annular cleaning brush 901 and the outer side wall of the support rods 902 are in contact with the inner side wall of the filter cartridge 3. The support rods 902 can provide support for the filter cartridge 3 and scrape off the material adhering to the inner side wall of the filter cartridge 3 during the extraction process. The annular cleaning brush 901 is located at the top of the filter cartridge 3 to avoid contaminating the extraction liquid during the extraction process. After the extraction is completed, the top cover 2 and the filter cartridge 3 are driven to move upward, which can automatically scrape off the material adhering to the inner side wall of the filter cartridge 3, resulting in a better cleaning effect. Furthermore, for ease of use, an electric push rod or similar device that drives the top cover 2 to move up and down can also be provided on the outside of the extraction tank 1. The extension and retraction of the electric push rod can automatically drive the filter cartridge 3 to move up and down for cleaning.

[0028] In this embodiment, the top of the top cover 2 is provided with a liquid inlet 201, through which extraction water or cleaning water can be added to the interior.

[0029] Working principle: First, crushed tea leaves and other materials are placed inside the filter cylinder 3, and then ice water is poured in for extraction. The sealing cap 5 is closed for sealing. During the extraction process, the filter cylinder 3 is rotated by the rotary drive mechanism 4, which can drive the flow of liquid inside the extraction tank 1 and improve the extraction efficiency. After extraction is completed, the cold extract liquid is discharged through the liquid outlet 6. The rotary drive mechanism 4 drives the filter cylinder 3 to rotate, which can also shake out the cold extract liquid soaked in the material, making the liquid discharge more thorough. The slag outlet 7 is opened to discharge the material inside the filter cylinder 3. Then, the top cover 2 and the filter cylinder 3 can be pulled upwards directly. The inner side wall of the filter cylinder 3 moves relative to the annular cleaning brush 901, which can scrape off the material adhering to the inner side wall of the filter cylinder 3. Clean water is circulated into the extraction tank 1 for rinsing. The second cleaning component 10 is fixed on the outer side wall of the filter cylinder 3. The rotary drive mechanism 4 drives the filter cylinder 3 to rotate, which in turn drives the second cleaning component 10 to rotate, which can clean the inner side wall of the extraction tank 1.
