Description

Technical Field

[0001] This invention belongs to the field of peeling machine technology, and particularly relates to a continuous discharge peeling machine. Background Technology

[0002] In the process of making nut products, it is often necessary to first peel the kernels of nuts such as peanuts, walnuts, and almonds. Peeling the kernels with a peeling device is a complex and tedious task. Manual peeling is not only slow, but also labor-intensive and inefficient. Therefore, a kernel peeling machine is extremely important.

[0003] Existing nut peeling machines generally operate on a single-feed-out basis, failing to achieve continuous feeding and discharging, resulting in low processing efficiency. Furthermore, existing nut peeling machines typically separate the skin from the kernel embryo through soaking in water or heating and roasting, but these methods have significant drawbacks: 1. Soaking in water: This generates wastewater containing the skin, requiring an additional wastewater treatment process. Since the kernels are wet, the absorbed moisture must be removed through air drying or even baking, further increasing the processing steps. Both wastewater treatment and dehydration processes increase the number of machines in the peeling machine, raising costs and increasing floor space. Insufficient drying can also lead to mold growth. 2. Heating and roasting: This reduces the moisture content of the kernels. Low-moisture kernels cannot meet the taste requirements of some nut products, limiting the use of peeled kernels. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a continuous discharge peeling machine to solve the problems of current nut granule peeling machines, such as inability to process continuously, generation of wastewater, need for dehydration, and limitations in the subsequent application of peeled nuts.

[0005] This invention provides a continuous discharge peeling machine, including a conveying device, which includes a guide pipe and a chain mechanism. The chain mechanism is located in the guide pipe and has multiple sets of baffles. A sealed space is formed between two baffles. The guide pipe has an inlet and an outlet.

[0006] The conveying device is equipped with a drive unit, which drives the chain mechanism to move along the guide pipe to convey the nuts that are put into the sealed space between the baffles from the inlet to the outlet for discharge.

[0007] The conveying device is equipped with a peeling device, which includes a blower. A section of guide pipe located between the inlet and the outlet is a working section. The working section has an air inlet and an air outlet. The air inlet is connected to the blower. The airflow blown by the blower enters the working section through the air inlet, agitates the kernels in the working section, and blows them out of the working section through the air outlet. This is to remove the skin of the kernels that have moved into the working section when the airflow passes through the working section.

[0008] In some embodiments, multiple baffles are connected in series by chains to form a chain mechanism.

[0009] In some embodiments, each of the end faces of the baffle has a boss, and multiple baffles are connected in series by hinges between adjacent bosses to form a chain mechanism, so that the sealed space between the baffles is annular.

[0010] In some embodiments, a feeding device is further included, wherein the feeding device has a feeding pipe connected to a feeding port, and the feeding device has a weighing mechanism for quantitatively adding nuts.

[0011] In some embodiments, the peeling device further includes a sealing sleeve that seals the outer side of the guide tube. A partition fixedly installed inside the sealing sleeve divides the space between the sealing sleeve and the guide tube into two air chambers. The sealing sleeve has an air inlet pipe and an air outlet pipe. The air inlet pipe and the air inlet are both connected to one air chamber, and the air outlet pipe and the air outlet are both connected to the other air chamber. The air inlet pipe is connected to a fan, and there are multiple air inlets and air outlets.

[0012] In some embodiments, multiple air inlets and multiple air outlets are arranged along the axial direction.

[0013] In some embodiments, the air inlet is located at the bottom and the air outlet is located at the top, so that the airflow blown by the fan passes through the working section from bottom to top.

[0014] In some embodiments, the drive device includes a drive motor and a helical drive rod;

[0015] The conveying device includes a guide pipe and a chain mechanism, the chain mechanism having multiple baffles;

[0016] The spiral blades of the spiral drive rod are installed in contact with the baffle. When the drive motor drives the spiral drive rod to rotate, the spiral drive rod drives the chain mechanism to move along the guide tube through the baffle.

[0017] In some embodiments, the helical drive rod includes a first helical drive rod and a second helical drive rod symmetrically arranged and located on both sides of the chain mechanism. The helical blades of the first helical drive rod and the second helical drive rod are simultaneously installed in contact with the same baffle, and multiple baffles are simultaneously installed in contact with the helical blades of the helical drive rod.

[0018] In some embodiments, the first helical drive rod and the second helical drive rod are respectively equipped with a first driven sprocket and a second driven sprocket, the output shaft of the drive motor is equipped with a drive sprocket, and a transmission chain is installed between the drive sprocket and the driven sprocket, the transmission chain surrounding the guide tube.

[0019] Based on the above technical solution, the conveying device driven by the drive device in this embodiment of the invention can continuously convey the kernels. When the kernels move to the working section during the conveying process, the airflow blown by the peeling device removes the kernel skin, thus achieving kernel peeling. Kernel peeling can be continuously processed. During the peeling process, the kernels are not baked or soaked, eliminating the problems of wastewater treatment, dehydration, and reduced kernel moisture content caused by baking or soaking. There is no need to set up the corresponding processing equipment, which reduces equipment costs and equipment footprint. This allows the kernels to meet diverse subsequent processing needs and solves the problems of current kernel granule peeling machines being unable to process continuously, generating wastewater, requiring dehydration, and having limited subsequent applications for peeled kernels.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0041] like Figures 1 to 3 As shown, in an illustrative embodiment of the continuous discharge peeling machine of the present invention, the continuous discharge peeling machine includes a conveying device 1, on which a driving device 2 and a peeling device 3 are mounted.

[0042] The conveying device 1 includes a guide pipe 14 and a chain mechanism 15. The guide pipe 14 is provided with an inlet 11 and an outlet 12. The chain mechanism 15 is located in the guide pipe 14 and moves along the guide pipe 14. The chain mechanism 15 has multiple sets of baffles 16, and a closed space is formed between two baffles 16, all of which are located on the guide pipe 14.

[0043] The guide pipe 14 and the chain mechanism 15 form a tubular chain conveying structure. The drive device 2 drives the chain mechanism 15 to move along the guide pipe 14. When the sealed space between the baffles 16 is aligned with the feed inlet 11, the nuts are put into the sealed space between the baffles 16 through the feed inlet 11. Driven by the drive device 2, the nuts are pushed by the baffles 16 of the chain mechanism 15, and thus move along the guide pipe 14. When the sealed space between the baffles 16 is aligned with the discharge outlet 12, the nuts are discharged from the sealed space between the baffles 16 through the discharge outlet 12, and thus discharged outside the conveying device 1.

[0044] The peeling device 3 includes a blower, and a section of guide pipe 14 located between the feed inlet 11 and the discharge outlet 12 is a working section 13. The working section 13 has an air inlet 131 and an air outlet 132, and the air inlet 131 is connected to the blower.

[0045] When the kernels move to the working section 13 under the push of the baffles 16 in the chain mechanism 15, the sealed space between the baffles 16 is aligned with the working section 13. The airflow blown by the fan enters the working section 13 through the air inlet 131 and blows into the sealed space between the baffles 16, so that the airflow acts on the kernels in the working section 13. Under the action of the airflow, the skin on the kernels is blown off. At the same time, the airflow blows the kernels up. Under the mutual friction between the kernels, the skin that is more firmly attached falls off, thus removing the skin. The airflow blows out of the working section 13 through the air outlet 132, so that the airflow passes through the working section 13. The removed skin is discharged from the guide pipe 14 with the airflow.

[0046] Because a closed space is formed between the baffles 16, when the closed space containing the kernels moves to the working section 13, the airflow blown by the fan enters the closed space through the air inlet 131, blowing up the kernels in the closed space, blowing off the skin, and causing the skin to fall off due to friction between the kernels. Compared to the overall internal space of the working section 13, the closed space between the baffles 16 is relatively small, avoiding the airflow from entering a larger space and dispersing, which would reduce the flow velocity. This allows the kernels to be subjected to a higher flow velocity airflow, thus making the skin detach more completely and thoroughly.

[0047] In the above illustrative embodiment, the conveying device of the continuous discharge peeling machine, driven by the drive device 2, continuously moves the kernels fed in through the inlet 11 along the guide pipe 14 of the conveying device 1 to the outlet 12 for discharge, thereby enabling continuous kernel conveying. During the conveying process, when the kernels move to the working section 13, the airflow blown by the peeling device 3 removes the skin, continuously peeling the kernels in the conveying process, realizing continuous kernel peeling and improving processing efficiency. The skin of the kernels is removed under the action of airflow, and the kernels do not need to be baked at high temperature or soaked, eliminating the problem of low kernel moisture content caused by high temperature baking, which increases the limitations of subsequent processing. This allows the kernels to meet diverse subsequent processing needs and also eliminates the trouble of dehydration and wastewater treatment caused by soaking. There is no need to set up corresponding treatment equipment, reducing the cost and floor space required for kernel peeling equipment, and solving the problems of current kernel granule peeling machines that cannot process continuously, generate wastewater, require dehydration, and have limitations in subsequent applications of peeled kernels.

[0048] The edge of the baffle 16 slides on the inner wall of the feed tube 14, thereby forming a closed space inside the feed tube 14 between the two baffles 16. The two baffles 16 guide the airflow blown out by the peeling device 3, so that it flows radially and passes through the closed space between the baffles 16 in the working section 13, ensuring that the airflow fully acts on the kernels in the closed space.

[0049] In some embodiments, multiple baffles 16 are connected in series via chains 17 to form a chain mechanism. Through the connection of chains 17, the multiple baffles 16 of the chain mechanism 15 move synchronously, and the chain mechanism 15 can rotate with the guide tube 14, making the chain mechanism 15 flexible in its rotation. Furthermore, the chains 17 are located in the middle of the sealed space between the baffles 16. The airflow blown into the sealed space by the peeling device 3 can bypass the chains 17 from both sides. Under the action of the airflow, some kernels move clockwise around the sealed space, while others move counterclockwise. The two groups of kernels moving in opposite directions generate more intense friction, making it easier for the kernel skin to peel off under this intense friction, resulting in more complete and thorough peeling.

[0050] The feed pipe 14 and the chain mechanism 15 are connected end to end, forming a closed-loop structure. This allows the chain mechanism 15 to continuously circulate within the feed pipe 14, constantly conveying the kernels from the inlet 11 through the working section 13 to the outlet 12. To prevent the peeled kernels from spilling, an outlet pipe 18 is installed on the outlet 12 to transport the peeled kernels to an external kernel collection box.

[0051] In some embodiments, such as Figure 9 As shown, each of the two end faces of the baffle 16 has a boss 19. Multiple baffles 16 are connected in series through hinges between adjacent bosses 19 to form a chain mechanism 15. Due to the hinges, the gap between two adjacent bosses 19 is small, which limits the turning angle of the chain mechanism 15, making it easier for the baffles 16 to be kept in the radial direction of the guide tube 14. This allows the baffles 16 to maintain sliding contact with the inner wall of the guide tube 14 around the circumference, maintaining the airtightness of the space between the baffles 16. In addition, the bosses 19 occupy the center of the airtight space between the baffles 16, making the airtight space between the baffles 16 annular. After the gas enters the working section 13, the width of the flow space is smaller, making the airflow more concentrated and faster, enhancing the purging effect on the kernels in the airtight space. Under the action of the airflow, the kernels can move along an arc trajectory. Under the centrifugal force, the kernels can slide more in contact with the inner wall of the working section 13. In addition to the friction between the kernels, the friction received by the kernels is further enhanced, improving the peeling effect of the kernels.

[0052] In some embodiments, the continuous discharge peeling machine further includes a feeding device 4. The feeding device 4 has a feeding pipe 41 connected to the feeding port 11. The feeding device 4 has a weighing mechanism. Nuts are fed into the feeding device 4. The weighing mechanism weighs the nuts that enter it. When the weight of the nuts in the weighing mechanism reaches a set weight, the set weight of nuts is released and sent to the feeding port through the feeding pipe 41, so that the nuts are quantitatively fed into the conveying device.

[0053] The nuts are added in batches and in measured quantities, so that the nuts are evenly distributed on the conveying device 1 from the inlet 11 to the outlet 12. This avoids the nuts being added in excess and clogging the conveying device 1. It also prevents the airflow blown in by the peeling device 3 from being blocked by the excessive nuts, thereby ensuring that the airflow speed is sufficient to blow off the skin and make the nuts jump and rub against each other, ensuring that the nuts are peeled thoroughly.

[0054] When the conveying device 1 has a guide pipe 14 and a chain mechanism 15 that moves in the guide pipe 14, each portion of nuts that have reached the set weight is put into a sealed space between the corresponding baffles 16, so that the weight of nuts in the sealed space between each baffle 16 is the same and moderate, and the airflow blown into each sealed space by the peeling device 3 can have a sufficient flow rate to ensure that the nuts in the sealed space can be peeled completely.

[0055] The weighing mechanism is located inside the feeding device housing 42 of the feeding device 4. The upper part of the feeding device housing 42 has a main hopper 43, and the feeding pipe 41 is located at the lower end of the feeding device housing 42. The weighing mechanism includes a weighing hopper, a weight sensor, and a weighing driver. The nuts fed into the main hopper 43 enter the feeding device housing and fall into the weighing hopper of the weighing mechanism. The weight sensor weighs the nuts falling into the weighing hopper. When the set weight is reached, the weighing driver drives the weighing hopper to flip, thereby pouring out the nuts and letting them fall into the feeding pipe, and then into the conveying device.

[0056] The weighing mechanism of the feeding device 4 can be replaced by a rotary feeding disc 44, such as Figure 7 As shown, the rotary feeding disc 44 is equipped with multiple sub-hoppers 45. When the lower end of the main hopper 43 is movably and sealed to the port at the top of the corresponding sub-hopper 45, the inner wall of the feeding device housing 42 seals the port at the bottom of the sub-hopper 45. Nuts from the main hopper 43 fall into and fill the sub-hopper 45. By rotating the rotary feeding disc 44, the sub-hopper 45 filled with nuts is moved away from the lower end of the main hopper 43. The inner wall of the feeding device housing 42 continues to seal the bottom of the sub-hopper 45 until the port at the bottom of the sub-hopper 45 filled with nuts is movably and sealed to the feeding pipe 41. At this point, the nuts in the sub-hopper 45 fall into the feeding pipe 41 and are then fed into the conveying device 1. Since each sub-hopper 45 has the same volume, the weight of nuts fed into the feeding pipe 41 from each sub-hopper 45 is the same, thus achieving quantitative feeding of nuts.

[0057] The rotary feeding disc 44 achieves quantitative feeding of nuts mechanically, with a simple structure and stable operation. The weighing mechanism achieves quantitative feeding of nuts electronically, making the weight of each feeding more accurate. This avoids the bottom of the main hopper 43 from chopping nuts that have not fully entered the distribution hopper 45 when the rotary feeding disc 44 rotates and detaches from the bottom of the main hopper 43, ensuring that the nuts fed into the conveying device 1 are more intact.

[0058] In some embodiments, such as Figure 8 As shown, the peeling device 3 further includes a sealing sleeve 32, which seals the outer side of the guide pipe 14. A partition 33 fixedly installed inside the sealing sleeve 32 divides the space between the sealing sleeve 32 and the guide pipe 14 into two air chambers 34. The sealing sleeve 32 has an air inlet pipe 321 and an air outlet pipe 322. The air inlet pipe 321 and the air inlet 131 are both connected to one air chamber 34, and the air outlet pipe 322 and the air outlet 132 are both connected to the other air chamber 34. The air inlet pipe 321 is connected to a fan, and both the air inlet 131 and the air outlet 132 have multiple outlets.

[0059] The blower blows air into an air chamber 34 through the air inlet pipe 321, causing the blown air to be blown into the guide pipe 14 through various air inlets 131, and then converged into another air chamber 34 through various air outlets 132, finally being discharged through the air outlet pipe 322. The interlayer between the sealing sleeve 32 and the guide pipe 14 is divided into two spaces by a partition 33, thereby dispersing the air inlet and outlet, allowing multiple air inlets 131 to simultaneously blow the kernels in the guide pipe 14. The kernels can be blown up at various points in the guide pipe, ensuring sufficient friction between the kernels and guaranteeing that the skin is fully removed. The number of air outlets 132 matches the number of air inlets 131 to prevent insufficient air outlets from obstructing the airflow and to avoid excessive air pressure in the guide pipe 14 due to the air inlet being greater than the air outlet, which could cause the chain mechanism to move poorly.

[0060] In some embodiments, multiple air inlets 131 and multiple air outlets 132 are arranged along the axial direction, that is, the air inlets 131 and the air outlets 132 are distributed along the length of the working section 13. When the sealed space between multiple baffles 16 is located within the working section 13, the multiple air inlets can blow air into each sealed space respectively, so that the kernels in the multiple sealed spaces are blown up by the airflow at the same time, and the peeled skin is discharged through each air outlet, thereby improving the efficiency of kernel peeling.

[0061] The partition 33 is located in the middle, evenly distributing the interlayer between the sealing sleeve 32 and the guide tube 14, so that the two air chambers 34 are symmetrically arranged. When multiple air inlets 131 and multiple air outlets 132 are arranged along the arc direction of the corresponding air chambers 34, the airflow can be evenly blown into one half of the guide tube 14 and evenly blown out the other half of the guide tube 14, so that the airflow passing through the guide tube 14 is fully distributed on the cross-section of the guide tube 14, thereby fully blowing up the kernels in all parts of the guide tube 14.

[0062] In some embodiments, the air inlet 131 is located at the bottom and the air outlet 132 is located at the top, so that the airflow blown by the fan passes through the working section 13 from bottom to top. As the airflow passes through the working section 13, it blows the kernels from bottom to top, so that the kernels deposited at the bottom of the working section under the action of gravity can be blown up. This ensures that all the kernels in the working section 13 are in motion under the action of the airflow, with sufficient friction between the kernels. The kernels jump up and then fall down by their own gravity, maximizing the range of movement after the kernels are blown up and increasing the probability of contact and friction between the kernels and other kernels during the movement, thereby ensuring that the kernels are completely and thoroughly peeled.

[0063] The air outlet pipe 322 of the sealing sleeve 32 is connected to the air inlet pipe 51 of the cyclone 5. The peeling skin is discharged from the sealing sleeve 32 through the air outlet pipe 322 and enters the air inlet pipe 51 of the cyclone. The airflow further blows the peeling skin in the air inlet pipe 51 into the cyclone 5, and the airflow is discharged through the air outlet pipe 52 of the cyclone 5. The peeling skin is discharged through the chip discharge port 53 of the cyclone 5, thus realizing the separation of the peeling skin and the airflow.

[0064] like Figure 5 As shown, the slub discharge port 53 is connected to the slub inlet 62 at one end of the auger housing 61. The skin separated from the slub 5 enters the auger housing 61 through the slub inlet 62. The auger 6 is located inside the auger housing 61 and rotates under the drive of the motor, transporting the skin inside the auger housing 61 to the discharge port 63 at the other end of the auger housing 61 for discharge. The skin is then transported to the external skin collection box, realizing the automatic collection of the kernel skin and preventing the waste of useful resources.

[0065] In some embodiments, the drive device 2 includes a drive motor 21 and a screw drive rod 22. The conveying device 1 includes a guide tube 14 and a chain mechanism 15, the chain mechanism 15 having a plurality of baffles 16. The helical blades of the screw drive rod 22 are mounted in contact with the baffles 16. When the drive motor 21 drives the screw drive rod 22 to rotate, the screw drive rod 22 pushes the baffles 16 to move along their axial direction, thereby causing the chain mechanism 15 to move in the guide tube 14.

[0066] If the driving force on the chain mechanism 15 is intermittently interrupted, the connection points between the baffles 16 will be suddenly pulled, easily causing the connection between the baffles 16 to break. In addition, the intermittent driving force causes the friction between the outer edge of the baffle 16 and the guide tube 14 to constantly switch between dynamic and static friction. The nuts pushed by the baffle 16 will also create resistance to its movement, easily causing uneven friction at various parts of the outer edge of the baffle 16. This leads to radial deflection of the baffle 16 relative to the guide tube 14, creating a gap between the baffle 16 and the guide tube 14. Part of the airflow blown into the space between the baffles 16 will flow radially, reducing the blowing effect of the airflow on the nuts between the baffles 16 and reducing the peeling effect of the nuts.

[0067] Therefore, when the spiral drive rod 22 rotates, its spiral blades always maintain sliding contact with the baffle 16, the thrust on the baffle 16 is continuous and stable, and the movement of the chain mechanism 15 is smooth. By driving the baffle 16 through the spiral drive rod 22, it is possible not only to prevent the connection between the baffles 16 from being broken and improve the life of the chain mechanism 15, but also to prevent the baffles 16 from tilting and ensure the airtightness of the space between the baffles 16, thereby ensuring the blowing effect of the airflow on the kernels and ensuring the peeling effect of the kernels.

[0068] In some embodiments, to make the chain mechanism 15 move more smoothly in the guide tube 14, further prevent the baffle 16 from deflecting radially relative to the guide tube 14, and ensure the airtightness of the space between the baffles 16, the spiral drive rod 22 includes a first spiral drive rod 221 and a second spiral drive rod 222 symmetrically arranged. The first spiral drive rod 221 and the second spiral drive rod 222 are respectively located on both sides of the chain mechanism 15, and the spiral blades of the first spiral drive rod 221 and the second spiral drive rod 222 are simultaneously in contact with the same baffle 16. The first spiral drive rod 221 and the second spiral drive rod 222 simultaneously push the two sides of the baffle 16, so that the baffle 16 moves smoothly and remains perpendicular to the axial direction. In addition, multiple baffles 16 are simultaneously installed in contact with the spiral blades of the spiral drive rod 22, so that the two spiral drive rods 22 drive multiple baffles 16 synchronously. The spiral drive rod 22 and the chain mechanism 15 are in a tight meshing state, so that the chain mechanism 15 between the two spiral drive rods 22 is parallel to it, thereby straightening and tightening the chain mechanism 15, so that it can move towards the feed port 11 in a more stable state, avoiding the chain mechanism 15 from becoming loose in the guide tube 14 and causing the baffles 16 to deviate after leaving the drive device 2, and keeping the baffles 16 perpendicular to the axis of the guide tube 14.

[0069] In some embodiments, since the feed tube 14 is a closed-loop structure, the chain mechanism 15 needs to circulate within the feed tube 14, such as... Figure 4As shown, the drive motor 21 is located on one side of the guide tube 14. The first helical drive rod 221 and the second helical drive rod 222 are respectively equipped with the first driven sprocket 25 and the second driven sprocket 26. The output shaft of the drive motor 21 is equipped with the drive sprocket 23. A transmission chain 24 is installed between the drive sprocket 23, the first driven sprocket 25 and the second driven sprocket 25. The transmission chain 24 surrounds the guide tube 14, so that the guide tube 14 passes through the area enclosed by the transmission chain 24.

[0070] To ensure that the transmission chain 24 surrounds the guide tube 14, the first driven sprocket 25 and the second driven sprocket 26 are located on the left and right sides of the guide tube 14, respectively, along with the first helical drive rod 221 and the second helical drive rod 222. The drive device 2 further includes a guide sprocket 27, and the guide sprocket 27 and the drive sprocket 23 are located on the front and rear sides of the guide tube 14, respectively. The transmission chain 24 passes through the four sprockets in sequence, thereby surrounding the guide tube 14.
