Stirring members 85 are arranged on both sides of the guide sleeve 83 through a rotating shaft 84. The stirring members 85 rotate with the rotation of the driving shaft 81, and rotate around the rotating shaft 84 under the action of the cold extraction liquid; The cold brew kettle 1 also includes an end cover 11 disposed on the top of the cold brew kettle 1, one side of the end cover 11 is rotatably connected to a sealing cover 12, a sealing handle 13 is disposed on the sealing cover 12, and one end of the driving component 5 is connected to the sealing handle 13 through the clamping assembly 4 to realize the opening and closing of the sealing cover 12.

[0019] The sealing handle 13 is clamped and fixed by the driving component 5 in cooperation with the clamping assembly 4. Under the action of the driving component 5, the sealing cover 12 is opened, and the cold extraction liquid is added to the cold extraction kettle 1. The processed jasmine flowers are added to the cold extraction device 6 in sequence. The cold extraction device 6 is placed inside the cold extraction kettle 1 through the lifting device, so that the cold extraction device 6 is sleeved on the driving shaft 81 under the action of the guide kit 83. The driving component 5 cooperates with the clamping assembly 4 to control the sealing cover 12 to be closed, and is locked by the locking structure on one side. The motor 9 is started, and the motor 9 drives the driving shaft 81 to rotate. The guide kit 83 is installed on the driving shaft 81 and is fixed inside the cold extraction device 6, so that when the driving shaft 81 rotates, it can drive the stirring member 85 installed on the guide kit 83 to stir. The jasmine flowers are turned over inside the cold extraction device 6 by the rotation of the cold extraction device 6. With the action of the stirring member 85, the contact area with the cold extraction liquid can be effectively increased, ensuring that the jasmine flowers are fully in contact with the cold extraction liquid, avoiding uneven cold extraction of the jasmine flowers, and performing The cold extraction effect and quality of jasmine dew are affected. A temperature sensor is provided on the inner wall of the cold extraction device 6, which can detect the temperature inside the cold extraction device 6 in real time to better promote the cold extraction effect of jasmine. When the temperature is higher than the set temperature, the circulation pump is turned on to allow the cold extraction liquid to enter the refrigeration box 2. At the same time, the cold air tank 3 introduces cold air into the refrigeration box 2. The cold extraction liquid enters the circulation pipe 21 and is cooled in the refrigeration box 2 before returning to the cold extraction kettle 1, thereby ensuring the cold extraction temperature of jasmine.

Since the stirring member 85 is arranged at an angle, the cold brew liquid is flowing during the rotation process, so that the cold brew liquid generates a certain thrust on the rotating stirring member 85, thereby causing the stirring member 85 to rotate around the rotating shaft 84, further increasing the fluidity of the cold brew liquid, thereby further increasing the contact with the jasmine flowers, ensuring the uniformity of the cold brew of the jasmine flowers, improving the effect of the cold brew of the jasmine flowers, and effectively shortening the cold brew time of the jasmine flowers.

The cold extraction device for jasmine dew according to claim 5, characterized in that: The clamping assembly (4) comprises a mounting plate (41) and clamping plates (43) slidably connected to both sides of the mounting plate (41); a gear (42) is mounted on the mounting plate (41); an axial end of the gear (42) is connected to a motor (9); the motor (9) is mounted on a side of the bottom plate (57) away from the electric push rod (56); two groups of clamping plates (43) are provided with teeth (44) meshing with the gear (42) on one side close to each other; the two groups of clamping plates (43) clamp the sealing handle (13) from the upper and lower sides respectively, and form a U-shaped structure.

8. The cold extraction equipment for jasmine dew according to claim 1, characterized in that: One end of the cold air tank (3) is connected to a shunt pipe (32) via a connecting pipe (31); the bottom of the shunt pipe (32) is connected to a refrigeration box (2) via an injection pipe; the injection pipe passes through the top of the refrigeration box (2) and is connected to a nozzle (33); the bottom of the refrigeration box (2) is connected to the cold air tank (3) via a return pipe (34).

9. A cold extraction process of jasmine dew, characterized by: Using the cold extraction device according to any one of claims 1 to 8 comprises the following steps: Step 1: Select fresh jasmine flowers as raw materials, perform preliminary screening, and place them in a low-temperature environment for 2-4 hours. Spread the refrigerated jasmine flowers evenly on a sieve and air-dry them for 1-2 hours to further remove moisture from the surface of the jasmine flowers. Step 2: Add cold brew liquid into the cold brew kettle (1), add processed jasmine flowers into three groups of cold brew cylinders (61) in sequence, and install the three groups of cold brew cylinders (61) and the cover plate (7) through interference fit between the clamping portion (65) and the clamping end (64), and use the lifting device to pass the cold brew cylinder (61) through the driving shaft (81) and place it on the limit plate (86), so that the cold brew cylinder (61) is installed inside the cold brew kettle (1); Step 3: Start the cold air tank (3) and the circulation pump on the circulation pipe (21) to keep the temperature of the cold brew liquid at the set cold brew temperature. The temperature sensor provided inside the cold brew kettle (1) can detect the temperature inside the cold brew kettle (1) in real time and transmit it to the control system connected thereto. During the cold brew process, the motor (9) controls the drive shaft (81) to drive the S-shaped stirring element (85) and the cold brew cylinder (61) to rotate, thereby increasing the contact area and contact efficiency between the jasmine flowers and the cold brew liquid. Step 4: After the cold extraction is completed, the jasmine dew obtained after the cold extraction is drained and collected through the drainage tube, the clamping component (4) clamps and fixes the sealing handle (13), and the driving component (5) drives the clamping component (4) to move to open the sealing cover (12), and the cold extraction cylinder (61) and the jasmine flowers inside are taken out through the lifting device.
