Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of plant fruit processing, in particular to a centrifugal crushing device and flesh and shell crushing and separation equipment. Background Art
[0002] After drying, the shells of some fruits are brittle and the flesh inside the shell will peel away from the shell. Alternatively, some fruits have naturally brittle shells that separate from the flesh (such as camellia seeds, chestnuts, longans, certain varieties of walnuts, and other nuts). For these fruits, only the flesh is needed, not the shell.
[0003] Here we take tea seeds as an example. Before pressing oil, the hard shell and kernel of the tea seeds need to be separated to prevent the hard shell from absorbing oil during the oil pressing process and affecting the oil yield.
[0004] Since the sizes of tea seeds vary, the separation of the fruits and shells of these plants generally requires screening the size of the fruits, and sending the fruits of different sizes to crushing and separation equipment suitable for fruits of different sizes. In the crushing and separation equipment, the shell of the fruit will be crushed, and then the shell and the pulp will be separated. The current crushing and separation equipment has poor adaptability to fruits of different sizes, and the crushing and separation speed is slow, which is not conducive to rapid production in the factory. Utility Model Content
[0005] The technical problem to be solved by the present invention is to provide a centrifugal crushing device and a meat shell crushing and separation device to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.
[0006] The solution of the utility model to solve its technical problems is:
[0007] Centrifugal crushing device, comprising:
[0008] A crushing shell, wherein the lower end of the crushing shell is provided with a meat and shell mixing outlet;
[0009] A centrifugal disc is installed in the crushing shell, the centrifugal disc comprising a centrifugal shaft, a disc body, and a plurality of centrifugal blades; the centrifugal shaft is rotatably connected to the crushing shell, the disc body is fixedly connected to the centrifugal shaft, the centrifugal blades are arranged above the disc body and fixed to the disc body, and the plurality of centrifugal blades are arranged around the circumference of the centrifugal shaft;
[0010] A centrifugal drive structure, wherein the output end of the centrifugal drive structure is drivingly connected to the centrifugal rotating shaft.
[0011] With the above technical solution, fruit falls into the center of the centrifugal disc after passing through the crushing feed hopper. As the centrifugal disc rotates, the fruit falling into the center of the centrifugal disc is thrown out by the centrifugal blades. After being thrown out by the centrifugal blades, the fruit collides with the inner wall of the crushing equipment housing, breaking the hard shell. Due to the fruit being sun-dried or oven-dried to a certain degree, or due to the characteristics of the fruit itself, the hard shell is separated from the kernel after being broken. This achieves automatic crushing of the fruit hard shell, which can improve the processing efficiency of the factory.
[0012] As a further improvement of the above technical solution, a crushing feed hopper is fixed to the upper end of the crushing shell, and the crushing feed hopper is arranged above the centrifugal disc. A crushing outlet is provided at the lower end of the crushing feed hopper, and the crushing outlet is arranged corresponding to the middle of the centrifugal disc.
[0013] As a further improvement of the above technical solution, the centrifugal disc also includes an annular upper baffle structure, which is arranged above the centrifugal blades and fixed to the centrifugal blades, and the inner wall of the upper baffle structure is in contact with the outer wall of the crushing feed hopper.
[0014] Through the above technical solution, by setting up an upper blocking structure, the seed kernels can be prevented from falling back into the middle of the centrifugal disk, thereby preventing the seed kernels from being thrown out a second time by the centrifugal blades, and preventing the seed kernels from directly colliding violently with the outer shell of the crushing equipment, thereby protecting the seed kernels and avoiding damage to the seed kernels.
[0015] As a further improvement of the above technical solution, the height of the bottom wall of the crushing shell gradually decreases from away from the meat-shell mixing outlet to the meat-shell mixing outlet.
[0016] Through the above technical solution, after the kernels and hard shells of the plant fruits are crushed, they will automatically move to the flesh and shell mixing outlet due to the action of gravity.
[0017] Meat shell crushing and separation equipment, including:
[0018] Equipment housing;
[0019] The centrifugal crushing device as described above;
[0020] Several separation components, the separation components include a separation feed hopper, a separation channel, and a separation fan; the separation feed hopper of at least one of the separation components is arranged below the meat shell mixing outlet; the separation feed hopper is connected to the separation channel, the separation fan is arranged at one end of the separation channel, and the other end of the separation channel is provided with a hard shell blowing outlet and a kernel outlet, and the hard shell blowing outlet is connected to the outer peripheral surface of the equipment casing.
[0021] Through the above technical solution, after the plant fruit is processed by the centrifugal crushing device, the mixture of the seed kernel and the hard shell flows out of the centrifugal crushing device. When the seed kernel and hard shell mixture is in the separation channel, the separation fan blows air to separate the seed kernel and the hard shell, and the lighter hard shell is blown to a place farther away from the separation fan, so that the hard shell can be directly blown out from the hard shell blowing outlet to the outside of the meat shell crushing and separation equipment, thereby realizing the automatic separation of the seed kernel and the hard shell, and improving the production efficiency of the factory.
[0022] As a further improvement of the above technical solution, it also includes a feed elevator, which is provided with a low-position feed end and a high-position feed end, the high-position feed end is arranged above the low-position feed end, and the high-position feed end is arranged above the crushing feed hopper.
[0023] Through the above technical solution, the feed elevator moves the material from the low-position feed end to the high-position feed end to realize the lifting and transfer of the material. The plant fruits transported to the high-position feed end will fall into the crushing feed hopper and then flow out from the crushing outlet.
[0024] As a further improvement of the above technical solution, the number of the separation components is set to at least three, and the multiple separation components are sequentially set to the first separation component, the second separation component and the third separation component, the seed kernel outlet of the front separation component is docked with the separation feed hopper of the rear separation component, and the seed kernel outlet of the last separation component extends out of the equipment casing.
[0025] Through the above technical solution, in the separation component, part of the hard shell is located on the side of the seed kernel close to the separation fan, and the seed kernel blocks part of the hard shell, making it impossible for the hard shell to be completely blown out. Therefore, the second separation component and the third separation component are added after the first separation component to perform secondary and tertiary blowing. When the seed kernel and the hard shell are separated again, the falling posture of the seed kernel and the hard shell will change, thereby making the separation of the seed kernel and the hard shell more thorough.
[0026] As a further improvement of the above technical solution, the second separation component is arranged above the third separation component, and a reflux elevator is provided between the second separation component and the third separation component. The reflux elevator is provided with a low-position reflux end and a high-position reflux end. The third separation component is provided with a reflux outlet, and the reflux outlet is provided on the side of the seed kernel outlet away from the separation fan; the low-position reflux end is connected to the reflux outlet, and the high-position reflux end is connected to the separation feed hopper of the second separation component.
[0027] With the above technical solution, some hard shells or light kernels that have not been blown out of the shell crushing and separation device after multiple blows will enter the return flow elevator through the return outlet and then flow back into the second separation component to continue the blow separation, thereby achieving a more thorough separation of hard shells and kernels.
[0028] As a further improvement of the above technical solution, the height of the second separation component is higher than that of the first separation component, the second separation component is docked with the first separation component through the reflux elevator, and the seed kernel outlet of the first separation component is docked with the low-position reflux end.
[0029] The beneficial effects of the utility model are that the hard shells of certain plant fruits can be automatically broken and the hard shells and kernels can be automatically separated, thereby improving the processing efficiency of the factory.
[0030] The utility model is used in the technical field of plant fruit processing. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Before pressing oil from camellia seeds, the hard shell and kernel of the seeds need to be separated to prevent the hard shell from absorbing oil during the pressing process and affecting the oil yield.
[0041] In the prior art, manual or semi-manual methods are usually used to crush the hard shell of camellia seeds and separate the hard shell and kernel. The separation speed is slow, which is not conducive to rapid production in the factory.
[0042] To address the aforementioned technical issue of low factory production efficiency, a shell crushing and separation device has been developed. The specific structure of the shell crushing and separation device is described in detail below. This device is used to crush and separate camellia seeds as an example. In other embodiments, the device can also be applied to fruits such as chestnuts and walnuts. Those skilled in the art can select the appropriate fruit.
[0043] Reference Figures 1 to 4 The meat shell crushing and separation equipment includes an equipment shell 100, a centrifugal crushing device 200, a separation component, a feed elevator 400 and a return elevator 500.
[0044] The feed elevator 400 is installed inside the equipment housing 100. Since elevators are common devices in the field of mechanical equipment, their specific structure will not be detailed here. The following is a brief description of the feed elevator 400. The feed elevator 400 has a high-level feed end 410 and a low-level feed end 420. The high-level feed end 410 is located above the low-level feed end 420. The feed elevator 400 moves material from the low-level feed end 420 to the high-level feed end 410 to achieve material lifting and transfer. The low-level feed end 420 of the feed elevator 400 is located outside the equipment housing 100.
[0045] The centrifugal crushing device 200 is fixedly installed inside the equipment housing 100 .
[0046] Specifically, the centrifugal crushing device 200 includes a crushing feed hopper 240 , a crushing shell 210 , a centrifugal disc 220 and a centrifugal drive structure 230 .
[0047] A meat-shell mixing outlet 211 is provided at the lower end of the crushing shell 210, and the bottom wall of the crushing shell 210 is inclined. From away from the meat-shell mixing outlet 211 to the meat-shell mixing outlet 211, the height of the bottom wall of the crushing shell 210 gradually decreases. In this way, the kernel and hard shell of the camellia seeds will automatically move to the meat-shell mixing outlet 211 due to the action of gravity after being crushed.
[0048] The crushing feed hopper 240 is fixedly connected to the crushing shell 210 and is arranged below the high-position feed end 410. A crushing outlet is provided at the lower end of the crushing feed hopper 240. The tea seeds transported to the high-position feed end 410 fall into the crushing feed hopper 240 and then flow out of the crushing outlet.
[0049] A rotating shaft connection portion is fixed in the middle of the crushing feed hopper 240 .
[0050] The centrifugal disc 220 is installed in the crushing shell 210 . Specifically, the centrifugal disc 220 includes centrifugal blades 221 , a disc body 222 , a centrifugal shaft 223 and an upper retaining structure 224 .
[0051] The lower end of the centrifugal shaft 223 extends through the crushing shell 210 and is rotatably connected thereto. The upper end of the centrifugal shaft 223 is connected to the shaft connection portion via a bearing. The upper and lower ends of the centrifugal shaft 223 are rotatably connected to different components, ensuring the stability of the centrifugal shaft 223 during rotation. This prevents the upper end of the centrifugal shaft 223 from shaking due to a lack of a connecting structure, thereby reducing noise during operation. Furthermore, the centrifugal shaft 223 is protected, extending its service life and ensuring the proper operation of the centrifugal crushing device 200.
[0052] The centrifugal drive structure 230 is arranged outside the crushing shell 210. The centrifugal drive structure 230 is arranged as a rotating motor. The centrifugal drive structure 230 is connected to the centrifugal shaft 223 through a gear belt, a synchronous belt, a chain sprocket or other structures. The centrifugal drive structure 230 drives the centrifugal shaft 223 to rotate. Those skilled in the art can select the transmission structure between the centrifugal drive structure 230 and the centrifugal shaft 223 according to actual needs.
[0053] The disc body 222 is a disc-shaped structure, and the centrifugal shaft 223 passes through the center of the disc body 222. The disc body 222 is fixedly connected to the centrifugal shaft 223. The crushing outlet is arranged above the center of the disc body 222.
[0054] The centrifugal blades 221 are disposed above the disc 222 and are fixedly connected to the disc 222. The number of the centrifugal blades 221 is set to be multiple, and the multiple centrifugal blades 221 are arranged equidistantly around the circumference of the centrifugal shaft 223.
[0055] Camellia seeds need to be dried or baked to a certain degree before they can be put into the present shell crushing and separation equipment for crushing and separation. The camellia seeds fall into the center of the centrifugal disk 220 through the crushing feed hopper 240. When the centrifugal disk 220 rotates, the camellia seeds that fall in the center of the centrifugal disk 220 will accumulate in the middle of the centrifugal disk 220 and then be thrown out by the centrifugal blades 221. After the camellia seeds are thrown out by the centrifugal blades 221, the camellia seeds will collide with the inner wall of the crushing equipment shell 100, causing the hard shell to break. Since the camellia seeds are dried or baked to a certain degree, the hard shell of the camellia seeds will be broken and the hard shell will be separated from the kernel.
[0056] The upper block structure 224 is arranged above the centrifugal blades 221. The upper block structure 224 is fixedly connected to the centrifugal blades 221. The upper block structure 224 is a circular ring-shaped component. The inner wall of the upper block structure 224 fits with the outer peripheral surface of the crushing feed hopper 240 (fitting here means that the inner wall of the upper block structure 224 is very close to the outer peripheral surface of the crushing feed hopper 240, and a certain gap may be left). By setting the upper block structure 224, the seed kernels can be prevented from falling back into the middle of the centrifugal disk 220, thereby preventing the seed kernels from being thrown out for the second time by the centrifugal blades 221, thereby protecting the seed kernels of the camellia seeds and preventing the seed kernels of the camellia seeds from being damaged.
[0057] The separation assembly includes a separation fan 310 , a separation channel 320 , and a separation feed hopper 330 .
[0058] The lower end of the separation feed hopper 330 is connected to the separation channel 320, the separation fan 310 is arranged at one end of the separation channel 320, and the other end of the separation channel 320 is provided with a seed kernel outlet 340 and a hard shell blowing outlet 350, and the hard shell blowing outlet 350 is connected to the outer peripheral surface of the equipment housing 100.
[0059] When the seed kernel and hard shell mixture is in the separation channel 320, the separation fan 310 blows air to separate the seed kernel and the hard shell, and the lighter hard shell is blown to a place farther away from the separation fan 310, so that the hard shell can be blown out directly from the hard shell blowing outlet 350 to the outside of the meat shell crushing and separation equipment.
[0060] Specifically, in this embodiment, the number of separation components is set to three (in other embodiments, the number of separation components can also be set to four, five, etc., and those skilled in the art can select the number of separation components according to actual needs), and the three separation components are respectively set to the first separation component 301, the second separation component 302 and the third separation component 303.
[0061] The first separation component 301 is arranged below the centrifugal crushing device 200, and the meat-shell mixing outlet 211 of the centrifugal crushing device 200 is arranged above the separation feed hopper 330 of the first separation component 301. The meat-shell mixture flows out from the meat-shell mixing outlet 211 and flows into the separation channel 320 from the separation feed port. The separation fan 310 blows air to separate the seed kernel and the hard shell. The hard shell is blown out of the meat-shell crushing and separation equipment from the hard shell blowing outlet 350, and the seed kernel flows out of the first separation component 301 from the seed kernel outlet 340.
[0062] The return elevator 500 is installed inside the equipment housing 100. Since elevators are common devices in the field of mechanical equipment, the specific structure of the elevator is not detailed here. The return elevator 500 is briefly described below. The return elevator 500 is equipped with a high return end 510 and a low return end 520. The high return end 510 is arranged above the low return end 520. The return elevator 500 moves material from the low return end 520 to the high return end 510 to achieve material lifting and transfer.
[0063] In the separation component, part of the hard shell is located on the side of the seed kernel close to the separation fan 310. The seed kernel blocks part of the hard shell, making it impossible to blow out the hard shell completely. Therefore, the second separation component 302 and the third separation component 303 are added after the first separation component 301 to perform secondary and tertiary blowing. When the seed kernel and the hard shell are separated again, the falling posture of the seed kernel and the hard shell will change, thereby making the separation of the seed kernel and the hard shell more thorough.
[0064] The low-position reflux end 520 of the reflux elevator 500 is arranged below the seed kernel outlet 340 of the first separation component 301, and the high-position reflux end 510 of the reflux elevator 500 is arranged above the separation feed hopper 330 of the second separation component 302 (that is, the separation feed hopper 330 of the second separation component 302 is connected to the seed kernel outlet 340 of the first separation component 301 through the reflux elevator 500). The height of the second separation component 302 is higher than that of the first separation component 301. The low-position reflux end 520 of the reflux elevator 500 can collect the seed kernels and hard shell mixture flowing out of the first separation component 301, and transport the seed kernels and hard shell mixture upward to the separation feed hopper 330 of the second separation component 302. The second separation component 302 can blow the seed kernels and hard shell mixture for a second time so that the seed kernels and hard shell mixture can be separated again.
[0065] The third separation component 303 is arranged below the second separation component 302. The separation feed hopper 330 of the third separation component 303 is connected to the seed kernel outlet 340 of the second separation component 302. The seed kernel and hard shell mixture flowing out of the second separation component 302 flows into the third separation component 303 for three blowing to further blow away the hard shell.
[0066] The kernel outlet 340 of the third separation component 303 extends out of the device housing 100, and the kernels of the crushed and separated camellia seeds flow out of the flesh-shell crushing and separation device from the kernel outlet 340 of the third separation component 303.
[0067] The third separation assembly 303 is further provided with a return outlet 360, which is located above the low-position return end 520 and on the side of the kernel outlet 340 away from the centrifugal blower of the third separation assembly 303. Hard shells or light kernels that have not been blown out of the shell crushing and separation equipment after multiple blows will enter the return elevator 500 through the return outlet 360 and then flow back into the second separation assembly 302 for further blow-through separation, thereby achieving a more thorough separation of the hard shells and kernels.
[0068] Specifically, in this embodiment, in order to reduce the space occupied by the meat shell crushing and separation equipment, the feed elevator 400 and the return elevator 500 in this solution both adopt vertical elevators. In other embodiments, inclined elevators can also be used. Those skilled in the art can select the specific structure of the feed elevator 400 and the return elevator 500.
[0069] The above specifically describes the preferred embodiments of the present invention, but the invention is not limited to the embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
