Description

Technical Field

[0001] The present application relates to the technical field of macadamia nut processing, and in particular to a nut centrifugal shell-kernel separation mechanism. Background Art

[0002] Macadamia nuts, also known as macadamia nuts, are a type of tree nut native to Australia. When macadamia nuts are dried, the lower end of the kernel contacts the shell due to gravity. When the kernel is heated, oil and sugar will seep out and flow to the lower end of the kernel, making the lower end of the kernel stick to the shell. If they are not separated, the kernel will stick to the shell after the shell is opened in half, and the shell and kernel cannot be effectively separated, thus affecting the kernel removal and consumption. For this reason, people have designed some equipment. For example, Chinese patent application number 202311431762.2 discloses a macadamia nut kernel-shell separation device and processing device that can improve the shell-kernel separation effect. The invention relates to a process in which a rotating disk is driven by a variable frequency motor, and the centrifugal force is used to throw out the macadamia nuts, so that the macadamia nuts hit the inner wall, and the impact force is used to separate the kernel from the shell. However, the swinging efficiency of the concave rotating disk is low. When there are many nuts, the nuts cannot be effectively thrown out, and the linear speed of the macadamia nuts is low when being thrown out, resulting in insufficient impact force and poor separation effect of the sticky shell. Therefore, a nut centrifugal shell-kernel separation mechanism is needed, so that the macadamia nuts can be efficiently thrown out to ensure sufficient impact force and improve the efficiency and quality of the sticky shell separation. Utility Model Content

[0003] In order to solve the above problems, the present application proposes a nut centrifugal shell and kernel separation mechanism, so that macadamia nuts can be thrown out efficiently to ensure sufficient impact force and improve the efficiency and quality of sticky shell separation.

[0004] This application is implemented through the following technical solutions:

[0005] The present application proposes a nut centrifugal shell and kernel separation mechanism, comprising: a bottom plate, a throwing channel, and a feed pipe. The throwing channel has multiple channels, and the throwing channels are distributed in a circular array on the upper part of the bottom plate. The inlet sides of the throwing channels are interconnected by a first baffle, and a first cover plate is provided on the upper part of the first baffle. The first cover plate and the first baffle bottom plate mutually form a cavity, the feed pipe is connected to the first cover plate, and the first cover plate is connected to the cavity; the cross-sectional area of ​​the throwing channel gradually decreases from the inlet side to the outlet side.

[0006] Furthermore, a rotating shaft is provided at the lower part of the base plate, the upper part of the rotating shaft is coaxially connected to the base plate, and a pulley is provided at the lower part of the rotating shaft, and the pulley is connected to an external motor through a belt.

[0007] Furthermore, the outlet of the throwing channel is offset backward by 10° to 20° along the rotation direction of the bottom plate.

[0008] Furthermore, the throwing channel includes a first arc plate, a second arc plate, and a second cover plate. The first arc plate and the second arc plate are welded to the upper part of the bottom plate, and the second cover plate is welded to the upper part of the first arc plate and the second arc plate. The bending curvature of the first arc plate is greater than that of the second arc plate.

[0009] Furthermore, a second baffle is provided on the outer periphery of the bottom plate, the second baffle is coaxially installed on the outer periphery of the bottom plate, and the inner diameter of the second baffle is 20 cm to 60 cm larger than the outer diameter of the bottom plate.

[0010] Furthermore, a reinforcing plate is provided on the outer periphery of the bottom plate, the reinforcing plate is welded to the outer periphery of the bottom plate, a through hole is provided on the reinforcing plate, and the outlet side of the throwing channel is connected with the outside through the through hole.

[0011] The beneficial effects of the present application are as follows: by arranging a cavity and a throwing channel on the bottom plate, the bottom plate is rotated at a high speed by being driven by an external motor, and after the macadamia nuts enter the cavity through the feed pipe, they are thrown out at a high speed, thereby hitting the second baffle plate, and the impact force is used to separate the adhered kernels from the shells, which is convenient for consumers to eat or take out the kernels. The cross-sectional area of ​​the throwing channel is gradually reduced, which can extend the time that the macadamia nuts stay in the throwing channel so that they can obtain a sufficient linear speed, thereby improving the efficiency and quality of separation from the shells.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

[0019] like Figures 1 to 3 As shown, an embodiment of the utility model provides a nut centrifugal shell and kernel separation mechanism, comprising: a bottom plate 1, a throwing channel 2, and a feed pipe 3. The throwing channel 2 has multiple channels, and the throwing channels 2 are distributed in a ring array on the upper part of the bottom plate 1. The inlet sides of the throwing channels 2 are interconnected by a first baffle 4. A first cover plate 5 is provided on the upper part of the first baffle 4. The first cover plate 5, the first baffle 4 and the bottom plate 1 mutually surround a cavity 6. The feed pipe 3 is connected to the first cover plate 5, and the first cover plate 5 is communicated with the cavity 6. The cross-sectional area of ​​the throwing channel 2 gradually decreases from the inlet side to the outlet side.

[0020] After the macadamia nuts are dried, they are sent to the separation equipment through the feeder and enter the cavity 6 through the feed pipe 3. The bottom plate 1 rotates at high speed driven by an external motor. After the macadamia nuts enter the cavity 6, they enter the throwing channel 2 under the action of centrifugal force. The cross-sectional area of ​​the throwing channel 2 becomes smaller, and the macadamia nuts squeeze and collide with each other, causing the macadamia nuts to rotate with the bottom plate 1, and then the macadamia nuts gradually move toward the outlet of the throwing channel 2 outside the bottom plate 1, and their linear speed gradually increases. The size of the outlet of the throwing channel 2 can only allow the macadamia nuts to pass one by one, thereby extending the time of the macadamia nuts in the throwing channel 2 so that the macadamia nuts can obtain sufficient linear speed. After being thrown out through the throwing channel 2, the macadamia nuts hit the second baffle 12, and the impact force is used to loosen the kernel in the shell. Consumers usually open the shell or remove the kernel equipment in half, and the kernel is completely separated from the shell after the impact. After opening the shell in half, the kernel can be quickly taken out.

[0021] In a specific embodiment, a rotating shaft 7 is provided at the bottom of the bottom plate 1, the upper part of the rotating shaft 7 is coaxially connected to the bottom plate 1, and a pulley 8 is provided at the bottom of the rotating shaft 7, which is connected to an external motor through a belt. With the external motor as the power source, the rotating shaft 7 drives the bottom plate 1 to rotate through the belt transmission, so that the macadamia nuts are thrown out by centrifugal force.

[0022] Preferably, the outlet of the throwing channel 2 is offset backward by 10° to 20° along the rotation direction of the bottom plate 1. After the outlet of the throwing channel 2 is offset backward, the throwing channel 2 is closer to the path of the macadamia nuts when they are thrown out, and the macadamia nuts can pass through the backward-moving throwing channel 2 more smoothly, avoiding the macadamia nuts from being stuck in the throwing channel 2.

[0023] In a specific embodiment, the throwing channel 2 includes a first curved plate 9, a second curved plate 10, and a second cover plate 11. The first curved plate 9 and the second curved plate 10 are welded to the upper part of the bottom plate 1, and the second cover plate 11 is welded to the upper part of the first curved plate 9 and the second curved plate 10. The inner walls of the first curved plate 9 and the second curved plate 10 are smooth, so that the round macadamia nuts can roll more smoothly in the throwing channel 2. The curvature of the first curved plate 9 is greater than that of the second curved plate 10, so that the outlet of the throwing channel 2 is offset backward after welding is completed.

[0024] Preferably, a second baffle 12 is provided on the periphery of the bottom plate 1, and the second baffle 12 is coaxially installed on the periphery of the bottom plate 1, and the inner diameter of the second baffle 12 is 20 cm to 60 cm larger than the outer diameter of the bottom plate 1. After the macadamia nuts are centrifugally thrown out, they hit the second baffle 12. When hitting, the shell first contacts the second baffle 12, and the shell is hard, so it can stop quickly. After that, the kernel shakes in the internal space of the shell under the action of inertia, thereby separating the place where the kernel is adhered to the shell. After the impact, the macadamia nuts fall into the lower part of the equipment under the action of gravity and are discharged from the outside of the equipment.

[0025] Preferably, a reinforcing plate 13 is provided on the periphery of the bottom plate 1, and the reinforcing plate 13 is welded on the periphery of the bottom plate 1. A through hole is provided on the reinforcing plate 13, and the outlet side of the throwing channel 2 is connected with the outside through the through hole. On the one hand, the reinforcing plate 13 improves the structural strength of the bottom plate 1 to prevent the bottom plate 1 from deforming. At the same time, the reinforcing plate 13 improves the mass of the bottom plate 1, so that it has a higher inertia after rotation, thereby improving the stability of the rotation speed of the bottom plate 1 during rotation.

[0026] Of course, the present application may have many other implementations. Based on the present implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present application.
