[0063] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0064] like Figures 1-6As shown, this embodiment provides a liquid nitrogen extraction device 100, which includes a accommodating chamber 13, a crushing device 2, a first driving device, and a separating device 4. The accommodating chamber 13 has a feed port 11 and a discharge port 12. The lower surface of the crushing device 2 has blades 21 for crushing the raw material. The first driving device drives the crushing device 2 to rotate and move in the vertical direction. The separating device 4 is arranged below the crushing device 2. The separating device 4 divides the accommodating chamber 13 into a first chamber 131 connected to the feed port 11 and a second chamber 132 connected to the discharge port 12. The separating device 4 includes a first partition 41 and a second partition 42. The first partition 41 has a first through hole 411, and the second partition 42 has a second through hole 421. The first through hole 411 and the second through hole 421 are staggered. The second partition 42 can move in the vertical direction to fit in with or away from the first partition 41. By providing the liquid nitrogen extraction equipment 100 having the first driving device, the crushing device 2 and the separating device 4, the process of crushing the raw materials and transferring the raw materials to the chamber for soaking the raw materials to extract the active ingredients is automated, thereby reducing the operator's workload and improving work efficiency.

[0065] Specifically, by providing a partitioning device 4, the partitioning device 4 divides the accommodating chamber 13 into two upper and lower chambers. The first chamber 131 is connected to the feed inlet 11, and the second chamber 132 is connected to the discharge port 12. This allows the first chamber 131 to become a smaller crushing space, while the lower second chamber 132 can become a larger extraction space. When the crushing device 2 is used to crush the raw materials in the first chamber 131, the oxygen content in the first chamber 131 is low, which can better prevent the raw materials from oxidizing during the crushing process and save the amount of liquid nitrogen used. By staggering the first through hole 411 and the second through hole 421, and the second partition 42 being able to move relative to the first partition 41 in the vertical direction to fit into or away from the first partition 41, when the second partition 42 fits into the first partition 41, the partition device 4 completely separates the first chamber 131 and the second chamber 132 to prevent the raw materials from entering the second chamber 132 without being crushed. When the second partition 42 is away from the first partition 41, the first chamber 131 is connected to the second chamber 132 through the first through hole 411, the space between the first partition 41 and the second partition 42, and the second through hole 421, so that the liquid nitrogen mixed with the crushed raw materials can flow from the first chamber 131 to the second chamber 132, and then the active ingredients in the raw materials can be extracted in the second chamber 132.

[0066] Specifically in this embodiment, the first driving device is connected to the crushing device 2 via a connecting shaft 32, and the connecting shaft 32 protrudes downward relative to the crushing device 2. Figure 3As shown, the first partition 41 has a clearance hole 412, through which the connecting shaft 32 can abut against the second partition 42, thereby moving the second partition 42 away from the first partition 41. By configuring the connecting shaft 32 to protrude downward relative to the pulverizing device 2, when the second partition 42 needs to move vertically downward to move away from the first partition 41, the first drive device can be used to drive the connecting shaft 32 to continue to descend, causing the connecting shaft 32 to abut against the second partition 42 and push the second partition 42 downward. By using the first drive device to drive the second partition 42 downward, there is no need to provide an additional drive device to drive the second partition 42 away from the first partition 41, thereby simplifying the structure of the liquid nitrogen extraction equipment 100.

[0067] Of course, in other embodiments, an independent driving mechanism may be provided for the second partition plate 42 to drive the second partition plate 42 to move at an appropriate time.

[0068] In this embodiment, if Figure 1 and Figure 2 As shown, the lower surface of the crushing device has a plurality of blades 21 for crushing the raw materials, and the plurality of blades are evenly distributed along the circumference of the crushing device.

[0069] In this embodiment, if Figure 1 As shown, the liquid nitrogen extraction equipment 100 further includes a restoring mechanism 7, which is disposed below the second partition 42. The restoring mechanism 7 exerts a vertical upward restoring force on the partition so that the second partition 42 fits against the first partition 41. By disposing the restoring mechanism 7 below the second partition 42, the second partition 42 can automatically move upward and fit back against the first partition 41 when the connecting shaft 32 no longer abuts against the second partition 42.

[0070] Specifically in this embodiment, the return mechanism 7 is a coil spring. There are two coil springs, which are symmetrically arranged below the second partition plate 42 . One end of the coil spring abuts against the second partition plate 42 , and the other end is fixed to the peripheral wall of the accommodating chamber 13 .

[0071] Of course, in other embodiments, the return mechanism 7 may also be other elastic elements in the prior art or structures with lifting capabilities, such as a leaf spring, an elastic rope, etc., which will not be described in detail here.

[0072] In this embodiment, if Figure 3 As shown, there are multiple first through holes 411, and the first through holes 411 are arranged in a rectangular shape on the first partition 41. Figure 4 As shown, there are also multiple second through holes 421, which are arranged in a rectangular shape on the second separator 42. Specifically, the first through hole 411 and the second through hole 421 are both circular holes, and their sizes can be determined according to the size of the raw material after being crushed, which will not be repeated here.

[0073] Specifically, if Figure 3 As shown, the arrangement area of ​​the first through holes 411 is the first arrangement area, and the first arrangement area is fan-shaped. Figure 4 As shown, the arrangement area of ​​the second through holes 421 is the second arrangement area, and the second arrangement area is fan-shaped. That is, in this embodiment, the first through holes 411 and the second through holes 421 are respectively concentrated in corresponding areas, and the first arrangement area and the second arrangement area are staggered to achieve the staggered arrangement of the first through holes 411 and the second through holes 421.

[0074] Specifically, in this embodiment, there are two first layout areas, which are symmetrically arranged on the first partition 41. There are two second layout areas, which are symmetrically arranged on the second partition 42. The first layout areas and the second layout areas have the same area, and the symmetry axes of the first layout areas are perpendicular to the symmetry axes of the second layout areas.

[0075] Of course, in other embodiments, the first through holes 411 may be evenly arranged throughout the first partition plate 41, and the second through holes 421 may be evenly arranged throughout the second partition plate 42, or the first through holes 411 and the second through holes 421 may be staggered, that is, the first through holes 411 may be arranged with gaps corresponding to the second through holes 421, and the second through holes 421 may be arranged with gaps corresponding to the first through holes 411. In further embodiments, the number of first arrangement areas and second arrangement areas may be greater, and it is only necessary to ensure that the first through holes 411 and the second through holes 421 are staggered, which will not be further elaborated here.

[0076] In this embodiment, if Figure 1 As shown, the liquid nitrogen extraction device 100 includes a main body 1, a receiving chamber 13 formed therein, and a first drive device including a rotational drive device and a translational drive device. The rotational drive device is connected to the pulverizing device 2 via a connecting shaft 32 to drive the pulverizing device 2 to rotate. The translational drive device is connected to the rotational drive device to drive the rotational drive device, the connecting shaft 32, and the pulverizing device 2 to move vertically. By providing the rotational drive device and the translational drive device, the rotation and vertical movement of the pulverizing device 2 can be performed independently.

[0077] Specifically in this embodiment, Figure 1As shown, the rotational drive device is a first motor 31 disposed above the main body 1, connected to the pulverizing mechanism via a connecting shaft 32. The translational drive device includes two second motors 33 fixed to the upper surface of the main body 1, two threaded rods 35, and a connecting plate 34. Each threaded rod 35 is connected to a second motor 33, which drives the threaded rod 35 to rotate. The connecting plate 34 is threadedly connected to the two threaded rods 35. The first motor 31 is fixed to the connecting plate 34. The motor drives the threaded rods 35 to rotate, causing the connecting plate 34 to move vertically, thereby driving the first motor 31 to move vertically.

[0078] Of course, in other embodiments, other structures in the prior art that can drive the crushing device 2 to rise, fall and rotate can also be used as the first driving device, which will not be described in detail here.

[0079] like Figure 1 As shown, the liquid nitrogen extraction equipment 100 further includes a stirring device 5 and a second driving device. The stirring device 5 is disposed at the bottom of the second chamber 132, and the second driving device drives the stirring device 5 to rotate. By providing the stirring device 5 and the second driving device, the raw material can be automatically stirred during the extraction of the active substance, thereby improving the extraction efficiency.

[0080] Specifically, if Figure 1 、 Figure 5 and Figure 6 As shown, the stirring device 5 is a scraper, which gradually becomes thinner from the middle position along both ends. The second driving device is a third motor 6, which is connected to the middle position of the scraper to drive the scraper to rotate.

[0081] In this embodiment, if Figure 1 As shown, the wall of the accommodating chamber 13 has a temperature-controlling interlayer 8, which has a liquid inlet 81 and a liquid outlet 82. By introducing a temperature-controlling fluid such as cold water into the temperature-controlling interlayer 8 with the liquid inlet 81 and the liquid outlet 82, the cooling loss in the accommodating chamber 13 can be reduced.

[0082] Since the extraction process of the active substance takes a long time, the cold loss in the accommodating chamber 13 needs to be minimized during the extraction process so that the raw materials and extractant in the accommodating chamber 13 are kept at a relatively low temperature, which is beneficial to improving the extraction efficiency.

[0083] In this embodiment, if Figure 1 As shown, the liquid nitrogen extraction equipment 100 further includes a surge tank 9, which is in communication with the first chamber 131. By providing the surge tank 9, the surge tank 9 can release pressure when there is too much liquid nitrogen or the liquid nitrogen vaporizes, thereby improving the safety of the liquid nitrogen extraction equipment 100.
