[0019] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0020] See also Figures 1 to 10 The present invention provides an extraction device for preparing freeze-dried anthocyanin powder, comprising an outer cylinder 1, to which a driving mechanism is fixedly connected, and an inner cylinder 2 is fixedly connected at a position where the driving mechanism is located inside the outer cylinder 1, and a partition 3 is fixedly connected at the center of the inner cylinder 2, and the partition 3 divides the inner cylinder 2 into two upper and lower cavities, and a through opening 4 is provided on the partition 3, and a compression mechanism for extrusion is fixedly connected at the center of the upper cavity of the inner cylinder 2, and an opening 4 of the partition 3 is equipped with an opening 4 for timely closing the opening 4, and the compression mechanism drives the opening 4 to timely connect the upper and lower cavities, and a feeding pipe 5 is provided on the outer cylinder 1, and the feeding pipe 5 extends into the inner cylinder 2, and a discharging mechanism is provided at the bottom end of the inner cylinder 2.

[0021] The inner cylinder 2 is driven to rotate by the provided driving mechanism, and the rotation of the inner cylinder 2 causes the compression mechanism to perform cyclic lifting and lowering, thereby compressing and crushing the blueberries in the upper cavity. During the rising process of the compression mechanism, the opening and closing mechanism is driven to open, so that the compressed and crushed blueberries enter the lower cavity through the opening 4 on the partition 3. When the compression mechanism continues to rise, the blueberries enter the inner cylinder 2 through the feeding pipe 5 for subsequent compression and crushing. During this process and the subsequent descending process, the opening and closing mechanism will close the opening 4, so that the compression mechanism compresses and crushes the blueberries again. When the compressed and crushed blueberries enter the lower cavity, the rotating inner cylinder 2 separates the juice and residue of the blueberries, and discharges the inner cylinder 2 through the corresponding discharging mechanism, thereby realizing a continuous production process, and the overall production process can be completed without the staff making corresponding changes to the device structure, thereby improving work efficiency and reducing the labor intensity of the staff.

[0022] See also Figure 8 The driving mechanism includes a motor 6 fixedly connected to the top of the outer cylinder 1, and the output end of the motor 6 extends to one end inside the outer cylinder 1 through a connecting shaft and is fixedly connected to a first gear 7. The first gear 7 is meshingly connected to a ring gear 8, and the ring gear 8 is fixedly connected to the top side wall of the inner cylinder 2.

[0023] When the production process is in progress, the motor 6 is started, and the motor 6 drives the first gear 7 to rotate through the connecting shaft. The rotation of the first gear 7 drives the ring gear 8 to rotate, and the rotation of the ring gear 8 drives the inner cylinder 2 to rotate, providing power for the subsequent working process and participating in the production process.

[0024] See also Figure 3 , Figure 5 , Fig. 9 and Fig.10 The compression mechanism includes a fixed sleeve 9 fixedly connected to the top of the inner wall of the outer cylinder 1, and a material discharge through hole 10 is opened on the fixed sleeve 9. A spiral groove 11 is opened at a position of the fixed sleeve 9 away from the gear ring 8. The spiral groove 11 is annular and connected end to end. The spiral groove 11 is slidably connected to a fixed block 12, and a compression plate 13 is fixedly connected to the fixed block 12. The compression plate 13 is inclined near the fixed sleeve 9. The compression plate 13 is slidably connected to the side wall of the inner cylinder 2 A sliding sleeve 14 is symmetrically hinged on one side of the compression plate 13 close to the gear ring 8, a connecting rod 15 is slidably connected in the sliding sleeve 14, an annular groove 16 is provided on one side of the compression plate 13 close to the gear ring 8, the connecting rod 15 is located in the annular groove 16, a sliding groove 17 is provided on one side of the outer cylinder 1 close to the compression plate 13, a closing plate 18 for timely closing the blanking through hole 10 is slidably connected in the sliding groove 17, and the closing plate 18 is hinged to the connecting rod 15 at one end away from the fixed sleeve 9.

[0025] The fixed sleeve 9 is fixedly connected to the outer cylinder 1. When the inner cylinder 2 rotates, the compression plate 13 driven by the inner cylinder 2 rotates, and the fixed block 12 performs a cyclic lifting motion along the spiral groove 11, so that the compression plate 13 performs a cyclic lifting motion. When the compression plate 13 rises, the compression plate 13 will drive the sliding sleeve 14 to move. Initially, there is a certain distance between the sliding sleeve 14 and the connecting rod 15. Before the sliding sleeve 14 contacts the connecting rod 15, when the compression plate 13 rises, the connecting rod 15 will not drive the closing plate 18 to move. When the sliding sleeve 14 continues to rise and moves, it contacts the connecting rod 15 and drives the connecting rod 15 to move. The movement of the connecting rod 15 drives the closing plate 18 to move, so that the closing plate 18 no longer closes the feeding hole 10, so that the blueberries fall into the partition 3 in the inner cylinder 2 through the feeding hole 10, and the partition 3 rotates so that the blueberries can be continuously and automatically moved from the fixed sleeve 9 to the partition 3, thereby realizing the automatic and continuous feeding of blueberries. When the compression plate 13 descends, in contrast to the above process, the closing plate 18 closes the feeding hole 10, and the blueberries no longer enter the inner cylinder 2. The compression plate 13 compresses and crushes the blueberries in the inner cylinder 2, thereby preventing the blueberries from entering the inner cylinder when the compression plate compresses and crushes the blueberries, resulting in incomplete crushing of some blueberries.

[0026] See also Figures 4 to 6 The opening and closing mechanism includes an opening and closing plate 19 rotatably connected to the partition 3, and the opening and closing plate 19 is fixedly connected to a gear shaft 20 at one end close to the inner cylinder 2, and a mounting groove 21 is provided at a position of the inner cylinder 2 close to the gear shaft 20, and a driving gear 22 is fixedly connected to one end of the gear shaft 20 extending into the mounting groove 21, and a sliding plate 23 is slidably connected to a position close to the driving gear 22 in the mounting groove 21, and a rack 24 is fixedly connected to the sliding plate 23, and the rack 24 is meshed with the driving gear 22, and the sliding plate 23 A pushing groove 25 is provided at the end away from the driving gear 22, and a pushing rod 26 is slidably connected in the pushing groove 25. The end of the pushing rod 26 located in the pushing groove 25 is fixedly connected to a first spring 27, and the other end of the first spring 27 is fixedly connected to the sliding plate 23. The mounting groove 21 is located at a position where the gear is away from the sliding plate 23 and is fixedly connected to a limiting block 28. The end of the sliding plate 23 close to the driving gear 22 is fixedly connected to a second spring 29, and the other end of the second spring 29 is fixedly connected to the bottom end of the mounting groove 21.

[0027] In the initial state, under the action of the second spring 29, the sliding plate 23 is in contact with the limiting block, and at the same time, the rack 24 is meshed with the driving gear 22, so that the opening and closing plate 19 closes the through-port 4, so that the compression plate 13 can compress and crush the blueberries. Before the compression plate 13 rises to a certain position, the compressed and crushed blueberries fall into the lower cavity, so that the uncrushed blueberries are prevented from directly entering the lower cavity, causing material waste, and preventing the blueberries from falling through the through-port 4 in the initial state. When the compression plate 13 rises, the compression plate 13 will abut against the push rod 26 and drive the push rod 26 to move, and the movement of the push rod 26 drives the sliding plate 23 to move The movement of the sliding plate 23 drives the rack 24 to move, and the movement of the rack 24 drives the driving gear 22 to rotate. The driving gear 22 rotates and drives the opening and closing plate 19 to rotate through the gear shaft 20, so that the opening 4 is no longer closed, so that the compressed and crushed blueberries enter the lower wall for subsequent processes. When the sliding plate 23 moves to the top of the installation groove 21, the compression plate 13 continues to rise, and the compression plate 13 presses the push rod 26 to overcome the elastic force of the first spring 27 so that the push rod 26 moves into the push groove 25, and the compression plate 13 is separated from the push rod 26. Under the action of the second spring 29, the opening and closing plate 19 is in the initial state, and the blueberries will enter the partition 3 again.

[0028] See also Figure 4 The limit block 28 keeps the opening and closing plate 19 in a state of closing the through opening 4 during the downward movement of the compression plate 13. The limit block 28 limits the sliding plate 23. When the compression plate 13 moves downward and contacts the push rod 26, the push rod 26 enters the push groove 25, so that the compression plate 13 moves below the push rod 26. In this process, the opening and closing plate 19 is in a state of closing the through opening 4.

[0029] See also Figure 6 Both ends of the push rod 26 outside the push groove 25 are inclined and abut against the compression plate 13 in time, so that the compression plate 13 can move to the two ends of the push rod 26 in time during the movement process.

[0030] See also Figure 7 The inner cylinder 2 is fixedly connected to a fixing frame 30 at a position below the partition 3, and a filter screen 31 is fixedly connected to the fixing frame 30, and the filter screen 31 separates the blueberry juice and residue.

[0031] See also Figure 3 The fixed sleeve 9 is fixedly connected to one end of the partition 3 with a collar 32, and the collar 32 is fixedly connected to a fixed rod 33. After the blueberries are compressed and crushed, the fixed rod 33 sweeps the juice and residue to the opening 4 so that the juice and residue fall into the lower cavity.

[0032] See also Figure 3 The fixed sleeve 9 passes through the outer cylinder 1 and is connected to the feed pipe 5 .

[0033] See also Figure 1 The discharging mechanism includes a discharging plate 34 rotatably connected to the fixing frame 30, and a discharging pipe 35 is fixedly connected to the bottom end of the outer cylinder 1 between the fixing frame 30 and the inner wall of the outer cylinder 1. The discharging plate 34 can be timely closed with the fixing frame 30 by a locking structure (such as a lock). When discharging, the discharging plate 34 is opened to discharge the residue, and the discharging pipe 35 can control the discharging through a valve, so that the blueberry juice is discharged in time.
