Description

TECHNICAL FIELD

[0001] The application relates to the technical field of nut processing, and in particular to a nut shell adhesion separation device. BACKGROUND

[0002] Macadamia nut, also known as Hawaiian nut, is a tree nut originally from Australia. After being picked, the macadamia nut needs to be subjected to processes such as green removal, cleaning, shelling, drying, and flavoring. The macadamia nut product mainly has two types of sale, i.e., with shell and kernel. The kernel of the macadamia nut is slightly smaller than the shell. Before drying, the kernel can move in the shell. During drying, the kernel exudes oil and sugar after being heated, so that the kernel and the shell are adhered together. If separation is not performed, the kernel will be adhered to the shell after half shelling, so that the kernel and the shell cannot be effectively separated, thereby affecting kernel taking and eating. Therefore, some equipment is designed to process the kernel and shell adhesion problem after drying. For example, a Chinese patent with the application number 202311431762.2 discloses a macadamia nut kernel and shell separation device and processing technology capable of improving the kernel and shell separation effect. A variable frequency motor drives a rotating disc to separate the macadamia nut by centrifugal force, so that the macadamia nut impacts on the inner wall to separate the kernel and the shell by impact force. However, the rotating disc with a concave shape has low throwing efficiency. When the macadamia nuts are more, the macadamia nuts cannot be effectively thrown out, so that the impact force is insufficient, and the kernel and shell adhesion separation effect is poor. Therefore, a new type of centrifugal disc is needed to efficiently throw out the macadamia nut, and a rotating member rotating in the opposite direction is needed to ensure that the kernel and shell of the macadamia nut after impact are separated by sufficient impact force, so as to improve the efficiency and quality of kernel and shell adhesion separation.

Therefore, the features defined with "first", "second" can explicitly or implicitly include at least one of the features. In addition, the technical solutions among various embodiments can be combined with each other, but it must be based on the realization of the ordinary skilled in the art, when the combination of technical solutions appears contradictory or cannot be realized, it should be considered that the combination of technical solutions does not exist, nor within the protection scope required by the present application.

[0030] As shown in Figures 1 to 7 An embodiment of the present application provides a nut shell adhering separation device, which comprises a shell 1, a centrifugal disc 2 and a feeding hopper 3. The lower part of the shell 1 is connected with the ground through a first support frame 4, and the shell 1 is provided with a second support frame 5. The second support frame 5 is provided with a rotating shaft 6, and the centrifugal disc 2 is installed on the upper part of the rotating shaft 6. The centrifugal disc 2 is provided with a cavity 7 in the middle part, and the upper part of the cavity 7 is provided with a connecting pipe 9. A plurality of throwing channels 8 are arranged on the outer periphery of the cavity 7. One end of the throwing channel 8 is communicated with the cavity 7, and the other end of the throwing channel 8 is opened. The feeding hopper 3 is installed above the shell 1, and the lower part of the feeding hopper 3 is communicated with the cavity 7 through the connecting pipe 9.

[0031] After the macadamia nuts are dried, they are fed into the feed hopper 3 by the feeding machine. Under the action of gravity, the macadamia nuts enter the cavity 7 through the connecting pipe 9. Under the action of the second motor 13, the centrifugal disc 2 rotates at high speed. After the macadamia nuts enter the cavity 7, they enter the throwing channel 8 under the action of centrifugal force. The cross-sectional area of the throwing channel 8 gradually decreases. The macadamia nuts collide with each other, so that the macadamia nuts rotate with the centrifugal disc 2. Then the macadamia nuts gradually move towards the outlet of the throwing channel 8 outside the centrifugal disc 2. The linear speed gradually increases. The size of the outlet of the throwing channel 8 can only allow the macadamia nuts to pass one by one, thereby prolonging the time of the macadamia nuts in the throwing channel 8, so that the macadamia nuts can obtain sufficient linear speed. The linear speed when the macadamia nuts leave is related to the rotating speed of the centrifugal disc 2 and the diameter of the centrifugal disc 2. However, since the macadamia nuts are accelerated and thrown out, the suitable diameter of the centrifugal disc 2 is 60-100 cm. If the diameter of the centrifugal disc 2 is increased beyond the above-mentioned value, the linear speed when the macadamia nuts leave will not be greatly improved, and the weight of the equipment will also be increased. In order to improve the impact force, the device drives the rotating member 101 to rotate in the opposite direction by the first motor 104. After the macadamia nuts are thrown out through the throwing channel 8, they hit the impact plate 105 moving in the opposite direction, thereby improving the impact force to ensure that the macadamia nuts after impact are separated from the shells, thereby improving the efficiency and quality of the shell separation. The consumer shell opening or kernel taking device usually opens the shell by half. The kernel and shell after impact are completely separated. After opening the shell by half, the kernel can be quickly taken out, thereby improving the whole kernel rate of the kernel, so as to improve the sales price of the product.

[0032] The gradually narrowing structure of the throwing channel 8 makes the macadamia nuts leave the throwing channel 8 one by one, thereby prolonging the residence time of the macadamia nuts. The linear speed of the macadamia nuts when leaving the throwing channel 8 is close to the linear speed of the outlet of the throwing channel 8. On the one hand, the throwing channel 8 obtains sufficient kinetic energy to hit the first baffle 10. On the other hand, the consistency of the speed of the macadamia nuts is high. Workers can adjust the rotating speed of the first motor 104 and the second motor 13 to control the impact speed of the macadamia nuts. The kernel can be separated while avoiding the kernel shell from being broken due to high speed, thereby improving the appearance quality of the macadamia nuts sold with shells.

[0033] In a preferred embodiment, the first baffle 10 is arranged in the casing 1 and surrounds the outer periphery of the centrifugal disc 2. The upper portion of the first baffle 10 is provided with a cover plate 11. The first baffle 10 is mainly used to block the macadamia nuts thrown at high speed. When the macadamia nuts hit the first baffle 10, the shell first contacts the first baffle 10 and can quickly stop due to the hard texture of the shell. Then the kernel shakes in the internal space of the shell under the action of inertia, thereby separating the kernel from the shell at the place where they are adhered. The cover plate 11 covers the upper portion of the first baffle 10 to block the macadamia nuts, so that the macadamia nuts fall into the discharge hopper 12 after hitting.

[0034] In a preferred embodiment, as shown in Figure 2 The shell 1 is provided with an outlet hopper 12 below the first baffle 10, and the outlet hopper 12 is connected with the first baffle 10. The outlet hopper 12 is provided with an outlet. The macadamia nuts blocked by the cover plate 11 fall into the outlet hopper 12 and are discharged outside the equipment through the outlet, realizing continuous operation of the equipment.

[0035] In a preferred embodiment, as shown in Figure 2 , Figure 4 , Figure 7 The first baffle 10 is provided with a rotating part 101. The middle part of the first baffle 10 is provided with a slot. The rotating part 101 is rotatably installed on the slot. The cross section of the rotating part 101 is H-shaped. The first baffle 10 is provided with a first roller 102 and a second roller 103. The first roller 102 is rotatably connected with the upper and lower end faces of the rotating part 101. The axis of the second roller 103 is parallel to the axis of the rotating part 101. The second roller 103 is rollingly connected with the outer periphery of the rotating part 101. The lower part of the second roller 103 is provided with a first motor 104. The output shaft of the first motor 104 is fixedly connected with the second roller 103. The rotating part 101 is installed on both sides of the first baffle 10 after passing through the slot. The first roller 102 supports and limits the upper and lower parts of the rotating part 101. Meanwhile, the second roller 103 limits the outer periphery of the rotating part 101. The rotating part 101 can smoothly rotate around the first baffle 10, thereby driving the impact plate 105 to reversely rotate. After the first motor 104 drives the second roller 103 to rotate, the rotating part 101 is driven to rotate through friction. In the mode of friction transmission, when a large number of macadamia nuts impact on the impact plate 105, the friction can play a buffering role, avoiding that the impact force directly acts on the first motor 104.

[0036] Preferably, the inner side of the rotating part 101 extends into the inner cavity of the first baffle 10. The rotating part 101 is provided with a plurality of impact plates 105. The rotating direction of the impact plates 105 is opposite to that of the centrifugal disc 2. After the macadamia nuts are thrown out, the impact plates 105 can impact the macadamia nuts in the opposite direction, improving the impact intensity of the macadamia nuts, thereby further improving the impact intensity, to ensure that there is enough impact force to separate the shells and kernels of the macadamia nuts after impact, improving the efficiency and quality of the shell-kernel separation.

[0037] In a preferred embodiment, the middle part of the cover plate 11 is provided with a first through hole.

The first baffle 10 is provided with a support block. The semicircular plates are installed on the upper part of the first baffle 10 through the support block. Since the connecting pipe 9 rotates with the centrifugal disc 2, the cover plate 11 leaves a certain gap with the connecting pipe 9. The cover plate 11 blocks the macadamia nuts while avoiding affecting the rotation of the centrifugal disc 2.

[0038] Preferably, the diameter of the centrifugal disc 2 is 60-100 cm, so that the macadamia nuts have a certain linear speed when leaving the throwing channel 8, and the inner diameter of the rotating member 101 is 20-60 cm larger than that of the centrifugal disc 2, so that the macadamia nuts have enough impact space.

[0040] Preferably, as shown in the drawings, Figure 6 the second support frame 5 is provided with a second baffle 15 on both sides, the second baffle 15 covers the top and both sides of the belt, and the second baffle 15 can prevent the macadamia nuts from being rolled into the belt pulley 14, so as to ensure the normal operation of the equipment.

[0041] In a specific embodiment, as shown in the drawings, Figure 4 the throwing channel 8 is arranged in an annular array on the centrifugal disc 2, a plurality of throwing channels 8 simultaneously throw out the macadamia nuts, so as to improve the processing efficiency of the equipment, the cross-sectional area of the inlet of the throwing channel 8 is larger than that of the outlet, so that the throwing channel 8 gradually narrows, thereby making the macadamia nuts pass through the outlet of the throwing channel 8 one by one, prolonging the residence time of the macadamia nuts, and thus ensuring that the macadamia nuts obtain a linear speed close to that of the centrifugal disc 2.

[0042] Specifically, as shown in the drawings, Figure 4 the outlet of the throwing channel 8 is offset backward by 10-20° along the rotation direction of the centrifugal disc 2, after the offset of the throwing channel 8, the path of the throwing channel 8 is closer to the throwing direction of the macadamia nuts, and the macadamia nuts can pass through the throwing channel 8 more smoothly, thereby avoiding the macadamia nuts being thrown into the throwing channel 8.

[0043] In a preferred embodiment, the diameter of the lower part of the feeding hopper 3 is smaller than the inner diameter of the connecting pipe 9, so as to avoid friction between the lower part of the feeding hopper 3 and the connecting pipe 9, and make the connecting pipe 9 rotate smoothly, and the lower part of the feeding hopper 3 extends into the connecting pipe 9 by 1-5 cm, so that the macadamia nuts can enter the connecting pipe 9 smoothly after entering the feeding hopper 3.
