Description

Technical Field

[0001] This invention relates to the field of pepper shell and seed separation, specifically to a pepper air-separation auxiliary heat drying and deseeding device and method. Background Technology

[0002] Sichuan pepper is a traditional plant used for both food and medicine. It belongs to the genus Zanthoxylum in the Rutaceae family. Currently, there are many imperfections in the Sichuan pepper industry. For example, there is still a great demand for Sichuan pepper seed removal. This is due to a variety of reasons: traditional seed removal processes rely on manual labor or semi-mechanized equipment, resulting in low efficiency, low seed removal rate, and high breakage rate, which makes it difficult to meet the needs of large-scale production.

[0003] The outer shell of Sichuan peppercorns is hard and tightly adhered to the kernel. Traditional mechanical shelling easily leads to kernel breakage, resulting in low separation efficiency (less than 60% shell-kernel separation rate) and difficulty in large-scale production. Currently, in addition to traditional manual sorting of peppercorn shells and peppercorns with seeds, various sorting methods have emerged, some of which have been well-developed and used for many years. The first method is mechanical vibrating sieving. This method uses a vibrating sieve to separate peppercorns based on the size difference between the shells and seeds. The sieve aperture is typically set at 1.5~2.5mm. Because the peppercorn shell diameter is relatively large (approximately 3~4mm), it remains in the upper layer, while the seeds and impurities fall through the sieve. This method is suitable for medium to large-scale industrial production, is technically mature, and has been used for many years. The second method is air separation. The principle is to place the peppercorns into an air separator; the lighter peppercorn shells are blown further away by the airflow and collected, while the heavier seeds fall to the nearest point due to gravity. The separation accuracy can be controlled by adjusting the airflow speed. This method is non-contact separation, reducing breakage, and using airflow instead of mechanical friction prevents the peppercorn shells from breaking, keeping the seeds intact. The third method is water separation. The principle is to soak the peppercorns in water, stir, and then let them stand. The seeds, due to their higher density, sink to the bottom, while the shells float on the surface. However, it is important to note that after removing the floating shells, they must be dried promptly to prevent mold growth.

[0004] Currently, there are three main threshing methods: The first is the rolling threshing method, which separates the shell from the seed through mechanical pressure or rolling friction. Dried peppercorns are laid flat and rolled with a stone roller or drum, breaking the shell and releasing the seed. However, this method suffers from a high shell breakage rate, and the mechanical pressure easily causes the peppercorn shells to break, reducing the appearance and quality of the finished product and affecting its price. The second method is the mechanical vibration threshing machine, which uses vibration and friction to mechanically separate the shell from the seed. The machine has multiple layers of screens, and high-frequency vibration separates the shell from the seed. This method is complex to maintain, as the vibration motor, screens, and other components are prone to wear and require regular replacement. The third method is the drying and opening threshing method, which uses hot air drying to reduce the moisture content of the peppercorns, causing them to open naturally and separating the shell from the seed. This method reduces mechanical damage, retains intact grains, and the natural opening during drying reduces the physical pressure on the shell caused by traditional rolling or vibration, resulting in a low shell breakage rate and an intact appearance in the finished product.

[0005] Therefore, the present invention provides a device and method for wind-selection and auxiliary heat drying of Sichuan pepper seeds. Summary of the Invention

[0006] The purpose of this invention is to provide a pepper air-separation auxiliary heat drying and deseeding device and method to overcome the shortcomings of existing technologies such as low efficiency, high labor intensity, incomplete separation of seed coats, and high deseeding breakage rate of traditional deseeding machines.

[0007] To achieve the above objectives, the present invention provides the following technical solutions: In a first aspect, the present invention provides a pepper air-separation auxiliary heat drying and deseeding device, comprising a collection bucket, wherein a sieve bucket is coaxially arranged inside the collection bucket; a power device is connected to the first end of the sieve bucket, and a drying box is connected to the second end; a drying device is connected to the bottom of the drying box, and a feeding device is connected to the top of the drying box; the feeding device includes a feeding pipe, and air-separation devices and pepper shell outlets are arranged opposite each other on both sides of the feeding pipe. The sieve barrel has a number of sieve holes evenly distributed on it. The size of the sieve holes is larger than the pepper seeds and smaller than the pepper shells. The bottom of the collection barrel is provided with a pepper seed outlet and a pepper shell outlet.

[0008] Furthermore, the screen barrel is generally conical in shape, with the inlet size smaller than the outlet size and the inlet height higher than the outlet size; a hollow screen barrel shaft is provided at the center of the screen barrel, and screen barrel connecting rods are provided on the upper and lower side walls of the screen barrel, which enable the screen barrel and the screen barrel shaft to rotate synchronously; a main shaft is connected inside the screen barrel shaft through screen barrel shaft bolts, and the main shaft is connected to a power unit.

[0009] Furthermore, the power unit includes a large pulley connected to the main shaft, one end of a belt is fitted on the large pulley, the other end of the belt is connected to a small pulley, the small pulley is connected to the output end of a reducer, and the input end of the reducer is connected to the main shaft motor.

[0010] Furthermore, the drying device includes a hot air control system, with a hot air pipe connected to one side and a hot air blower connected to the other side; the hot air pipe is connected to a hot air box, which is connected to a drying box; a hot air motor is connected to the hot air blower, which dries the peppercorns in the drying box under the action of the hot air control system; and the drying box is provided with a drying box outlet connected to a sieve barrel.

[0011] Furthermore, the hot air box and the drying box are connected by a strip-shaped air outlet, the opening of which is smaller than the size of the peppercorn.

[0012] Furthermore, the feeding device also includes a feeding hopper, with a feeding pipe connected below the feeding hopper. A pull-out baffle is provided at the connection between the feeding hopper and the feeding pipe. A feeding hopper vibrator is provided on the feeding hopper, and a feeding pipe vibrator is provided on the feeding pipe.

[0013] Furthermore, the air separation device includes an air duct, which is arranged opposite to the pepper shell outlet on both sides of the feed pipe. The air duct is connected to a fan, which is connected to a motor. The fan generates airflow that blows into the feed pipe through the air duct.

[0014] Furthermore, the collection bucket is equipped with a collection bucket vibrator.

[0015] Furthermore, it also includes a supporting frame, to which the collection bucket, power unit, feeding device, and air separation device are all connected.

[0016] Secondly, the present invention provides a method for using a Sichuan pepper wind-separation auxiliary heat drying and seed-removing device, which includes the following steps: The raw peppercorns are placed into the feeding device, and the peppercorn shells are blown into the peppercorn shell outlet one by the air separation device, while the peppercorns with seeds enter the drying box. The drying device dries the peppercorns with seeds in the drying box. The dried peppercorns with seeds will become a mixture of peppercorn shells, peppercorn seeds and peppercorns with seeds. The mixture enters the sieve barrel, which is rotated by a power device, causing the peppercorns with seeds in the mixture to be deseeded. The peppercorn seeds fall through the sieve holes into the collection barrel and are discharged from the peppercorn seed outlet, while the peppercorn shells are discharged from the peppercorn shell outlet.

[0017] Compared with the prior art, the present invention has the following beneficial technical effects: This invention provides a peppercorn air-separation auxiliary heat drying and deseeding device. Through air-separation devices positioned opposite each other on both sides of the feed pipe and the peppercorn shell outlet, the peppercorn shells in the raw peppercorn can be initially separated. The combination of the drying box and the drying device achieves the peppercorn drying function, preventing the damp peppercorns from clumping and affecting subsequent deseeding. A sieve barrel and a collecting barrel are coaxially arranged, allowing peppercorn seeds to fall into the collecting barrel through the sieve holes during the rotation of the sieve barrel, while the peppercorn shells are discharged from the sieve barrel outlet. This forms a processing procedure of first removing the peppercorn shells, then drying, and finally deseeding, fundamentally solving the problem of the dispersed nature of traditional peppercorn processing where screening, drying, and deseeding need to be operated separately, laying the foundation for subsequent efficiency improvement and quality assurance. This invention, through the combination of mechanical structure and hot air drying, evaporates the moisture inside the peppercorn shells, loosening the bond between the peppercorn shells and seeds, allowing the seeds to be naturally expelled. A drum screen is used to separate the peppercorn shells and seeds, achieving rapid and low-loss separation of the peppercorn shells and seeds.

[0018] Specifically, the conical design of the sieve barrel, with a small inlet and a large outlet, and a high inlet and low outlet, utilizes the dual effects of gravity and centrifugal force: after the material enters the sieve barrel, it will flow naturally along the inclined inner wall towards the outlet, while continuously tumbling during rotation, increasing the collision frequency between the peppercorns and the inner wall of the sieve barrel, thus promoting the removal of seeds from peppercorns with seeds; the structure of a small inlet and a large outlet can prevent material from accumulating at the inlet, and the lower outlet design accelerates the discharge of material, thereby improving the seed removal efficiency and reducing the residence time of material in the sieve barrel, thus reducing the risk of mold.

[0034] Example 1 See Figures 1 to 5 This invention provides a pepper air-separation auxiliary heat drying and deseeding device, including a collection bucket 15. A sieve bucket 13 is coaxially arranged inside the collection bucket 15. The sieve bucket 13 is installed inside the collection bucket 15. Both the sieve bucket 13 and the collection bucket 15 are thin-walled structures with their central axes coincident. A power device is connected to the first end of the sieve bucket 13, and a drying box 9 is connected to the second end. A drying device is connected below the drying box 9, and a feeding device is connected above the drying box 9. The feeding device is used to transport pepper raw materials and includes a feeding pipe 5. Air-separation devices and pepper shell outlets 3 are arranged opposite each other on both sides of the feeding pipe 5. The air-separation devices are used to perform preliminary sorting of the pepper raw materials, blowing away the lighter pepper shells and collecting them through the pepper shell outlets 3. Heavier peppercorns with seeds enter the drying box 9. The drying device removes moisture from the peppercorns in the drying box 9, causing the unremoved peppercorns to open due to reduced moisture, weakening the bond between the peppercorn seeds and shells, or even causing them to spit out directly. The sieve barrel 13 has several evenly distributed sieve holes 14, the size of which is larger than the peppercorn seeds but smaller than the peppercorn shells. Driven by a power device, it can rotate, causing the dried peppercorns to detach from the seeds, becoming peppercorn seeds and shells. The peppercorn seeds are smaller than the size of the sieve holes 14 and fall into the collection barrel 15. The bottom of the collection barrel 15 is provided with a peppercorn seed outlet 16 and a peppercorn shell outlet 17. The peppercorn seeds are discharged from the collection barrel 15 through the peppercorn seed outlet 16 and collected, while the peppercorn shells are discharged through the peppercorn shell outlet 17.

[0035] In this embodiment, the screen barrel 13 is generally conical in shape, with the inlet size smaller than the outlet size and the inlet height higher than the outlet size. A hollow screen barrel shaft 22 is provided at the center of the screen barrel 13, and screen barrel connecting rods 21 are provided on the upper and lower side walls of the screen barrel 13. The screen barrel connecting rods 21 enable the screen barrel 13 and the screen barrel shaft 22 to rotate synchronously. A main shaft 23 is connected inside the screen barrel shaft 22 through screen barrel shaft bolts 24. The main shaft 23 is connected to a power device, which provides power for the rotation of the screen barrel 13.

[0036] Example 2 See Figures 1 to 5 Based on Embodiment 1 of the present invention, the power device is further described.

[0037] The power unit includes a large pulley 29 connected to the main shaft 23. One end of a belt 30 is fitted on the large pulley 29. The other end of the belt 30 is connected to a small pulley 28. The small pulley 28 is connected to the output end of a reducer 26. The input end of the reducer 26 is connected to a main shaft motor 27. The reducer 26 is driven by the main shaft motor 27. The output end of the reducer 26 drives the small pulley 28, which drives the large pulley 29 through the belt 30. The large pulley 29 drives the main shaft 23, which in turn makes the sieve barrel 13 rotate. In the rotating sieve barrel 13, the peppercorns with seeds jump and collide continuously, causing the peppercorns with seeds to separate into peppercorn shells and peppercorn seeds. The peppercorn seeds fall into the collection barrel 15 through several evenly distributed sieve holes 14 on the sieve barrel 13. Since the inlet size of the sieve barrel is smaller than the outlet size and the inlet height is higher than the outlet height, the peppercorn shells can fall into the collection barrel 15 from the end of the sieve barrel 13. The peppercorn seeds and peppercorn shells are collected from the bottom of the collection barrel 15 through the peppercorn seed outlet 16 and the peppercorn shell outlet 17, respectively.

[0038] Example 3 Based on Embodiment 2 of the present invention, the drying device is further described.

[0039] The drying device includes a hot air control system 25, which is connected to a hot air pipe 8 on one side and a hot air blower 20 on the other side; the hot air pipe 8 is connected to a hot air box 10, which is connected to a drying box 9; the hot air blower 20 is connected to a hot air motor 33, and the hot air blower 20 dries the peppercorns in the drying box 9 under the action of the hot air control system 25; the drying box 9 is provided with a drying box outlet 12 connected to a sieve barrel 13.

[0040] When the peppercorns with seeds left by the air separation device enter the drying box 9, the hot air control system 25 sends a command to the hot air motor 33 to drive the hot air blower 20 to run. The hot air generated by the hot air blower 20 is delivered to the hot air box 10 through the hot air pipe 8, so that a continuous high temperature airflow environment is formed inside the hot air box 10, providing the heat source required for drying the drying box 9.

[0041] In a preferred embodiment of the present invention, the hot air box 10 and the drying box 9 are supplied with air through the strip-shaped air outlet 11, the opening of which is smaller than the size of the peppercorn; the high-temperature airflow in the hot air box 10 enters the interior of the drying box 9 through the strip-shaped air outlet 11.

[0042] Example 4 Based on Embodiment 3 of the present invention, the feeding device and the air separation device are further described.

[0043] The feeding device also includes a feeding hopper 1, which is cone-shaped with rectangular cross-sections at both the top and bottom, the upper cross-section being larger than the lower cross-section. A feeding pipe 5 is connected to the bottom of the feeding hopper 1. A pull-out baffle 2 is provided at the connection between the feeding hopper 1 and the feeding pipe 5. The flow rate of the pepper raw material is controlled by moving the pull-out baffle 2 back and forth. A feeding hopper vibrator 4 is provided on the feeding hopper 1. The feeding hopper vibrator 4 can prevent the pepper from piling up and ensure smooth feeding. A feeding pipe vibrator 7 is provided on the feeding pipe 5. Under the action of the feeding pipe vibrator 7, the pepper can enter the drying box 9 and the cone 13. The air separation device includes an air duct 19, which is arranged on both sides of the feed pipe 5 opposite to the pepper shell outlet 3. The air duct 19 is connected to a blower 18, which is connected to a motor 32. The blower 18 generates airflow that is blown into the feed pipe 5 through the air duct. The airflow generated by the blower 18 acts on the pepper raw material in the feed pipe 5, causing the lighter pepper shells to be collected through the pepper shell outlet 3, while the relatively heavier peppers with seeds enter the next process.

[0044] In some embodiments of the present invention, a collection bucket vibrator 6 is provided on the collection bucket 15, which allows the pepper seeds and pepper shells to flow smoothly out of the collection bucket 15 through the pepper seed outlet 16 and the pepper shell outlet 17.

[0045] In some embodiments of the present invention, a supporting frame 31 is also included, and the collection bucket 15, power unit, feeding device and air separation device are all connected to the frame 31.

[0046] Example 5 This invention also provides a method for using a Sichuan pepper wind-separation auxiliary heat drying and seed-removing device, which includes the following steps: The raw peppercorns are placed into the feeding device, and the peppercorn shells are blown into the peppercorn shell outlet 1 by the air separation device. The peppercorns with seeds enter the drying box 9. Open the pull-out baffle 2 of the feed hopper 1 and slowly pour the peppercorn raw material to be processed into the feed hopper 1. Adjust the opening degree of the pull-out baffle 2 according to the amount of peppercorn raw material to control the feeding speed and avoid the device from being blocked due to excessive feeding.

[0047] Start the feed hopper vibrator 4 and the feed pipe vibrator 7. The feed hopper vibrator 4 prevents the peppercorn raw material from accumulating in the feed hopper 1, ensuring that the raw material falls evenly into the feed pipe 5; the feed pipe vibrator 7 prevents the peppercorns from getting stuck in the feed pipe 5, ensuring stable material conveying.

[0048] Start the motor 32 corresponding to the blower 18. The blower 18 generates airflow, which is blown into the feed pipe 5 through the air duct 19. Since the air duct 19 and the pepper shell outlet 3 are arranged opposite each other on both sides of the feed pipe 5, the airflow will blow the lighter pepper shells in the raw pepper material toward the pepper shell outlet 3 and discharge them from the outlet; while the relatively heavier peppers with seeds are not affected by the airflow and continue to fall down along the feed pipe 5 into the drying box 9.

[0049] The drying device dries the peppercorns with seeds in the drying box. The dried peppercorns with seeds will become a mixture of peppercorn shells, peppercorn seeds and peppercorns with seeds. Based on the moisture content of the Sichuan peppercorn raw materials, the appropriate drying temperature and hot air force are set through the hot air control system 25. Different moisture levels of Sichuan peppercorns require different drying conditions; setting the parameters appropriately can ensure the drying effect while avoiding excessively high temperatures that could damage the quality of the Sichuan peppercorns.

[0050] When the hot air motor 33 is started, the hot air blower 20 begins to work. The hot air generated is delivered to the hot air box 10 through the hot air pipe 8 under the control of the hot air control system 25. The hot air box 10 evenly sends the hot air into the drying box 9 through the strip-shaped air outlet 11, and performs auxiliary heating and drying on the peppercorns with seeds that have entered the drying box 9 to obtain a mixture.

[0051] The mixture enters the sieve barrel 13, which is rotated by a power device, causing the peppercorns with seeds in the mixture to be deseeded. The peppercorn seeds fall through the sieve holes into the collection barrel 15 and are discharged from the peppercorn seed outlet 16, while the peppercorn shells are discharged from the peppercorn shell outlet 17.

[0052] After drying, the mixture enters the screen barrel 13 through the drying box outlet 12 on the drying box 9. Since the screen barrel 13 is conical in shape and the inlet size of the screen barrel 13 is smaller than the outlet size and the inlet height is higher than the outlet size, the mixture will move along the inner wall of the screen barrel 13 towards the outlet under the action of gravity.

[0053] The main shaft motor 27 is started, and the power is transmitted to the small pulley 28 after being reduced in speed by the reducer 26. The small pulley 28 drives the large pulley 29 to rotate through the belt 30. The main shaft 23 connected to the large pulley 29 rotates accordingly, which in turn drives the screen barrel 13 to rotate synchronously through the screen barrel shaft 22 and the screen barrel connecting rod 21. During the rotation of the screen barrel 13, the peppercorns with seeds in the mixture are subjected to centrifugal force and collision, achieving seed removal. At the same time, the screen holes 14 evenly distributed on the screen barrel 13 are larger than peppercorn seeds but smaller than peppercorn shells, allowing peppercorn seeds to fall through the screen holes into the collection barrel 15, while peppercorn shells and peppercorns with seeds that have not been completely removed continue to move towards the outlet as the screen barrel 13 rotates. The collection barrel vibrator 6 is started, and the vibration of the collection barrel 15 prevents the peppercorn seeds from accumulating and clogging inside the barrel, ensuring that the peppercorn seeds can be smoothly discharged from the peppercorn seed outlet 16 at the bottom of the collection barrel 15. When the peppercorn shells and peppercorns with seeds that have not been completely deseeded move to the outlet of the sieve barrel 13, the peppercorns with seeds that have not been completely deseeded will be further deseeded during the subsequent rotation process. Finally, the peppercorn shells are discharged from the peppercorn shell discharge port 2 17 at the bottom of the sieve barrel 13, completing the entire process of peppercorn air separation, drying and deseeding.

[0054] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
