The plurality of rotating hopper structures are circumferentially arranged on the outside of the rotating cylinder. One side of the rotating hopper structure is in contact with the inner wall of the partition cylinder. The rotating hopper structure is configured such that when the rotating cylinder rotates, the partition cylinder rubs the rotating hopper structure to rotate.

[0011] A freezing device is used to freeze the moisture in the material inside the rotating hopper structure; the cold air generated by the freezing device passes through a gas channel opened in the middle of the rotating cylinder and exchanges heat with the rotating hopper structure; when the cold air flows, it drives the rotating cylinder to rotate through blades, and the blades are axially connected in the gas channel.

[0012] A vacuum sublimation device is used for the vacuum sublimation of ice crystals in the material within the rotating hopper structure. The air inlet of the vacuum sublimation device is connected to several of the rotating hopper structures.

[0013] Optionally, the separator is fixed inside the housing, and the separator has a rotating cavity that runs through the left and right sides in the middle.

[0014] The separator cylinder is made of thermally conductive metal.

[0015] Optionally, the rotating cylinder has an I-shaped cross-section; both ends of the rotating cylinder are used for sealing cooperation with the rotating cavity;

[0016] The rotating cylinder is made of thermally conductive metal.

[0017] Optionally, a crossbar is rotatably connected to the middle of the rotating cylinder. The crossbar is disposed in the gas flow channel. One end of the crossbar is fixed to the housing.

[0021] Optionally, a limiting ring is fixedly connected to the separator cylinder, the limiting ring is located inside the air intake chamber, and the limiting ring is in a limiting engagement with the rotating cylinder.

[0022] Optionally, a permeable ring plate is fixedly connected inside the vacuum sublimation chamber, and the permeable ring plate is coaxially arranged with the rotating chamber.

[0023] Optionally, the rotating hopper structure includes a second crossbar, which is fixed to the outside of the rotating cylinder and located between the two ends of the rotating cylinder;

[0029] In use, after the rotating drum slides out from the feeding port on one side of the shell, the leech material is placed into several rotating hopper structures. Then, the rotating drum is pushed back, and the freezing device is started. The freezing device generates a low-temperature airflow that circulates inside the shell. Specifically, the airflow enters the shell from one end through the gas channel of the rotating drum to the other end. As the airflow passes through the gas channel, the cold air exchanges heat with the material in the rotating hopper structure, carrying away heat and freezing the moisture in the material. At the same time, as the cold air flows, the blades cause the rotating drum to rotate. The rotation of the rotating drum drives the rotating hopper structure to move relative to each other, and under the action of rubbing against the inner wall of the partition cylinder, it rotates, causing the leeches inside to turn over, thus avoiding uneven freezing.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] Reference Figures 1 to 2 This invention discloses a freeze-drying device for producing freeze-dried leech powder, comprising:

[0037] Casing 1;

[0038] The partition cylinder 10 is fixedly connected inside the housing 1;

[0039] Rotating cylinder 17 is rotatably disposed in the middle of dividing cylinder 10, and rotating cylinder 17 is configured to slide out from the feeding port opened on one side of housing 1;

[0040] Several rotating hopper structures are used to hold Hirudo medicinalis material. Several rotating hopper structures are arranged circumferentially on the outside of the rotating cylinder 17. One side of the rotating hopper structure is in contact with the inner wall of the partition cylinder 10. The rotating hopper structure is configured such that when the rotating cylinder 17 rotates, the partition cylinder 10 rubs the rotating hopper structure to rotate.

[0041] The freezing device 4 is used to freeze the moisture in the material inside the rotating hopper structure. The cold air generated by the freezing device 4 passes through the gas channel opened in the middle of the rotating cylinder 17 and is heat exchanged with the rotating hopper structure. When the cold air flows, it drives the rotating cylinder 17 to rotate through the blades 9. The blades 9 are axially connected in the gas channel.

[0042] Vacuum sublimation device 3 is used for vacuum sublimation of ice crystals in materials within a rotating silo structure. The air inlet of vacuum sublimation device 3 is connected to several rotating silo structures.

[0043] In use, after the rotating cylinder 17 slides out from the feeding port on one side of the shell 1, the leech material is placed into several rotating hopper structures, and the rotating cylinder 17 is pushed back. The freezing device 4 is then started, and the freezing device 4 generates a low-temperature airflow that circulates within the shell 1. Specifically, the airflow enters the other end of the shell 1 through the gas channel of the rotating cylinder 17 from one end of the shell 1. As the airflow passes through the gas channel, the cold air exchanges heat with the material in the rotating hopper structure, carrying away heat and freezing the moisture in the material. At the same time, as the cold air flows, the rotating cylinder 17 rotates through the blades 9. The rotation of the rotating cylinder 17 drives the rotating hopper structure to move relative to each other, and it rotates under the action of rubbing against the inner wall of the partition cylinder 10, causing the leeches inside to turn over, thereby avoiding uneven freezing.

[0044] As an optional implementation, the separator 10 is fixedly connected to the housing 1. The separator 10 has a rotating cavity that runs through the left and right sides in the middle. The rotating cylinder 17 is rotatably disposed in the rotating cavity. The separator 10 divides the interior of the housing 1 into an air inlet cavity 12 on the left, a vacuum sublimation cavity 13 in the middle, and an exhaust cavity 14 on the right. The side wall of the rotating cavity is provided with a number of air holes 11 for communicating with the vacuum sublimation cavity 13.

[0045] The separator 10 is made of thermally conductive metal.

[0046] As an optional implementation, the rotating cylinder 17 has an I-shaped cross-section; both ends of the rotating cylinder 17 are used for sealing cooperation with the rotating cavity;

[0047] The rotating cylinder 17 is made of thermally conductive metal.

[0048] The middle of the separator cylinder 10 is provided with a rotating cavity that runs through the left and right sides. The rotating cylinder 17 is rotatably arranged in the rotating cavity. Therefore, the air inlet cavity 12 and the exhaust cavity 14 are connected through the gas flow channel. Neither the air inlet cavity 12 nor the exhaust cavity 14 are connected to the vacuum sublimation cavity 13, which facilitates the formation of a vacuum environment in the vacuum sublimation cavity 13.

[0049] The rotating cylinder 17 has an I-shaped cross-section. The end of the rotating cylinder 17 is sealed at the end of the rotating cavity. A sealing ring can be installed at the end of the rotating cylinder 17, which not only does not affect the rotation of the rotating cylinder 17 in the rotating cavity, but also ensures the isolation between the air inlet cavity 12 and the vacuum sublimation cavity 13.

[0050] As an optional implementation, a crossbar 5 is rotatably connected to the middle of the rotating cylinder 17. The crossbar 5 is set in the gas flow channel. One end of the crossbar 5 is fixed in the housing 1, and the other end of the crossbar 5 is detachably connected to a cover plate 16 for sealing the feed port. The blade 9 is rotatably connected to the crossbar 5.

[0051] The rotating cylinder 17 is slidably engaged with the crossbar 5, and the crossbar 5 is provided with a limiting mechanism that engages with the blade 9.

[0052] As an optional implementation, the limiting mechanism includes a limiting block 8, which is axially connected to the crossbar 5, and the limiting block 8 is in a limiting engagement with the blade 9.

[0053] As an optional implementation, an air distribution plate 2 is fixedly connected inside the air intake chamber 12. The air distribution plate 2 is located near the air intake end of the gas flow channel, and one end of the crossbar 5 is fixedly connected to the air distribution plate 2.

[0054] As an optional implementation, a limiting ring 18 is fixedly connected to the separator cylinder 10. The limiting ring 18 is located inside the air intake chamber 12 and is in a limiting engagement with the rotating cylinder 17.

[0055] As an optional implementation, a venting ring plate 15 is fixedly connected inside the vacuum sublimation chamber 13, and the venting ring plate 15 is coaxially arranged with the rotating chamber.

[0056] A feeding port is provided on one side of the housing 1. When in use, the cover plate 16 is removed and the rotating cylinder 17 is pulled out. The rotating cylinder 17 slides along the crossbar 5. The limiting block 8 and the blade 9 are matched to prevent the rotating cylinder 17 from coming off the crossbar 5. After the material is filled, it is pushed back into the rotating cavity. The limiting ring 18 is matched with the rotating cylinder 17. Then the cover plate 16 is installed. The end of the cover plate 16 and the crossbar 5 can be connected by threads. A sealing ring is set at the contact point between the edge of the cover plate 16 and the feeding port.

[0057] The end of the separator cylinder 10 is flared. The air distribution plate 2 is fixed to the air inlet side of the separator cylinder 10 so that the cold air can be evenly distributed and then enter the flared mouth of the separator cylinder 10 to converge and blow into the gas flow channel, driving the blades 9 to rotate, so that the rotating cylinder 17 rotates synchronously.

[0058] As an optional implementation, the rotating hopper structure includes a second crossbar 6, which is fixed to the outside of the rotating cylinder 17 and located between the two ends of the rotating cylinder 17.

[0059] Several ball cages 7 for holding leech material are rotatably connected to the crossbar 2 6, and the ball cages 7 are in contact with the inner wall of the rotating cavity.

[0060] As an optional implementation, the air inlet of the refrigeration device 4 is connected to the exhaust chamber 14, and the air outlet of the refrigeration device 4 is connected to the air inlet chamber 12.

[0061] The vacuum sublimation device 3 is connected to the vacuum sublimation chamber 13;

[0062] The outer wall of shell 1 is covered with a thermal insulation layer.

[0063] The refrigeration device 4 is selected from common refrigeration equipment. The refrigeration device 4 includes at least an air pump. The air outlet of the air pump is connected to the air inlet chamber 12, and the air inlet of the air pump is connected to the exhaust chamber 14. The air pump increases the flow rate in the gas flow channel, so as to facilitate the rotation of the rotating cylinder 17 by the blades 9.
