Description

Technical Field

[0001] This invention relates to the field of raw material processing. More specifically, this invention relates to a system for processing Sichuan pepper leaf powder. Background Technology

[0002] my country has a long history of cultivating Sichuan pepper, but in production and daily life, we mainly utilize its pericarp, with very little utilization and research on other products such as seeds, branches, and leaves. This not only wastes resources but also causes environmental pollution. In recent years, the planting area of ​​green Sichuan pepper has expanded rapidly, and currently, the planting area of ​​green and red Sichuan pepper accounts for nearly 7:3. Moreover, because the harvesting of green Sichuan pepper mostly uses large-branch pruning, a large amount of by-products such as branches and leaves are wasted. Research on the development and utilization of Sichuan pepper by-products is now urgent. These by-products mainly include seeds, leaves, and thorns.

[0003] Sichuan pepper seeds are a major byproduct of Sichuan pepper fruit peel production, with a theoretical yield of 120% of the peel's yield, accounting for about two-thirds of the total weight of Sichuan pepper. However, they have long been underutilized. In production areas, large quantities of Sichuan pepper seeds are used as fuel or fertilizer, or even discarded as waste. The value of Sichuan pepper seeds is far underestimated, even though they are rich in protein, phospholipids, minerals, and vitamin E. Except for a lower level of lysine, the content of other nutrients is higher than that of soybeans, making them a relatively complete protein resource. They can be used as feed for chickens and pigs, but due to the lack of a complete development chain, the industry is incomplete, and most Sichuan pepper seeds are treated as waste and not developed.

[0004] Harvesting Sichuan pepper leaves after the pepper fruits have matured generally does not affect the following year's yield and production. Sichuan pepper buds are rich in protein, fat, cellulose, calcium, phosphorus, and iron, and have a high amino acid content, 13.9 times that of bracken fern. Sichuan pepper leaves also have a high flavonoid content; currently, 16 types of flavonoids have been identified in Sichuan pepper leaves. However, because the leaves cannot be directly collected, they cannot be directly used.

[0005] The chemically active components in Sichuan pepper bark are not much different from those in Sichuan pepper leaves. However, the bark is not as easy to obtain as the leaves, and harvesting the bark causes more damage to the Sichuan pepper tree. Therefore, there has been almost no research on it in China. In practical applications, because the branches still contain bark after being peeled from the trunk, they cannot be used directly. At the same time, when used for recycling, it can easily cause injury to people. The current treatment methods are all landfill rotting or incineration, which have an impact on the environment.

[0020] It should be noted that in the description of this invention, the orientation or positional relationship indicated by the terms is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description. It does not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0021] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed", "equipped", "sleeved / connected", "connected", etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this invention can be understood according to the specific circumstances.

[0022] A system for processing Sichuan pepper leaves into powder, such as Figure 1 As shown, it includes: Harvesting unit 1 is used to separate pepper leaves and peppers from pepper branches. The pepper branches obtained after separation can be fed into a crushing module for processing, and the resulting powder is fermented to form fertilizer raw material. The peeling unit 2 is used to separate the remaining pepper leaves from the pepper branches after harvesting. This allows the pepper leaves to be connected to the subsequent processing unit 6 at this stage to process the pepper leaves. The primary screening unit 3 is connected to the discharge port I of the harvesting unit 1 to initially separate the pepper leaves and peppers. The primary screening unit 3 mainly uses a vibrating sieve to separate the material output from the harvesting unit 1, so that the peppers are separated from the material for further processing. A large amount of pepper leaves and other aggregates flow into the secondary screening unit 4. The secondary screening unit 4 is connected to the discharge port II of the primary screening unit 3 and performs secondary separation of pepper, pepper seeds, pepper thorns, and pepper leaf dust contained in the pepper leaves after the initial separation. It is used to separate pepper, pepper seeds, pepper thorns, and pepper leaf dust, so that the separated pepper leaves can flow directly into the crushing unit, while other aggregates are further processed by the processing unit 6. The crushing unit 5 is connected to the discharge port Ⅲ of the secondary screening unit 4 through the suction pipe to crush the screened pepper leaves. In actual application, the crushing unit 5 includes a front crushing module 50 and a rear drying module 51. The crushing module 50 crushes the green pepper leaves. The processed slurry enters the extraction module for processing to obtain the corresponding extract I. The waste residue is dried and used as raw material for feed. Both extract I and extract II can be used as raw materials for feed preparation, or as raw materials for other insect repellent and bactericidal products. The processing unit 6 is connected to the discharge port V of the secondary screening unit 4 to crush and microwave the separated peppercorns, peppercorn seeds and peppercorn thorns to obtain extract II. It is used to perform secondary deep processing on the by-products so that the raw materials obtained can be directly used as feed and fertilizer raw materials, thereby increasing the utilization rate of peppercorns in the processing process. The mixing unit 7 is used to mix the extract obtained from the processing unit 6 with the pepper leaf powder obtained from the crushing unit 5. Through the action of the mixing unit 7, the raw materials can maintain their original efficacy to a large extent, while facilitating storage and use. In this system, the connection between the units is achieved through a matching screw conveyor or lifting mechanism.

[0023] In the above technical solutions, such as Figures 1-2 The processing unit 6 includes a crushing module 61 and an extraction module 62, wherein the crushing module 61 is configured to include: Two sets of crushing rollers 610 are arranged opposite each other in space. They are used to crush peppercorns, peppercorn seeds, peppercorn thorns and small peppercorn branches, etc., to break down the tough parts of the raw materials, so that the crushing effect is better when they are crushed later. A cutter 611 is installed at the output end of the crushing roller to cut long strips of material into predetermined lengths. It is used to cut long strips of material into predetermined lengths so that it can be directly cooperated with the crusher at the rear end for crushing, reducing unnecessary downtime caused by the material getting tangled in the crushing components. The crusher 612 is set on the discharge side of the cutter. The structure of the crusher is conventional equipment, so the equipment will not be described here. It is only necessary to control the particle size of the crushed material to be 120-200 mesh. The surface of the first set of rollers at the front end is configured to have a planar structure, the surface of the second set of rollers at the rear end is configured to have a corrugated structure, or the surface of the second set of rollers arranged opposite to each other is provided with intermeshing tooth grooves 613.

[0024] Working principle: By crushing the peppercorns, peppercorn seeds, peppercorn thorns, and small peppercorn branches through a flat-structured roller, the material is flattened in space. The corrugated roller, with its uneven structure, can soften the flat material, making it easier to crush in the later stages.

[0025] In the above technical solutions, such as Figure 1 , Figure 3 The extraction module 62 is configured to include: Fermentation tank 620 is used for fermenting the powder output from the crushing module; A filter (not shown) used for filtering fermented materials; A reactor (not shown) is used for microwave extraction of fermentation residue. The reactor is existing technology and is mainly used for pressurizing or heating the residue. The microwave extraction frequency is 500-900MHz and the extraction time is 0.5-1.5h. The fermentation tank is configured to include: The double-layered insulated barrel 6201 has a heating mechanism 6202 on its inner wall to control the temperature inside the barrel. A barrel lid 6204 with a feed pipe 6203a is mounted on the lid. A sealing ring 6205 is mounted on the side wall of the lid that mates with the barrel body. The sealing ring is a hollow I-shaped structure, with one end fitted onto the inner ring of the upper edge of the barrel body and the other end mating with an annular retaining ring on the inner wall of the lid, i.e., the retaining ring is located in the groove of the sealing ring. The barrel body and the lid are connected by a snap lock. A temperature detection mechanism 6206 and a pressure detection mechanism 6207 are mounted on the inner wall of the barrel body. A control panel 6208 is mounted on the outer wall of the barrel body, used to monitor the internal temperature and pressure in real time through the temperature and pressure detection mechanisms, and to control whether to perform evacuation, venting, or heating operations via the control panel. The tilting stirring mechanism 6209 installed inside the barrel is used to stir the materials inside the barrel. Its stirring blade adopts a spiral structure, which allows the materials below to be lifted by the rotation of the stirring shaft to complete the mixing of the materials. At the same time, it makes the temperature inside the barrel uniform. In actual application, the tilting stirring mechanism can be installed at the bottom of the inside of the barrel or on the barrel lid. The air inlet pipe 6203b and air extraction pipe 6203c installed on the barrel lid enable fermentation to take place inside the fermentation barrel at a predetermined temperature and / or a predetermined pressure, thanks to the design of the fermentation barrel.

[0026] The working principle involves adding compound bacteria to crushed Sichuan pepper leaf powder and / or aggregate powder at a ratio of 0.8%-1.5% of the powder, followed by fermentation at 45-55℃ for 18-36 hours. The mixture is then filtered to collect the fermentation residue and fermentation broth separately. The fermentation residue is then extracted using 95wt% ethanol via microwave at a frequency of 900MHz for 1.5 hours. Finally, the extract is obtained by filtration.

[0027] In the above technical solutions, such as Figure 4 - Figure 5 The filter is configured to include: A filter unit 621 is installed upstream; The membrane filtration unit located downstream of the filtration unit is designed to improve the clarity of the extract, making it suitable for direct use as a raw material for other products. In practical applications, it can be selected and used according to the amount of material and the current working mode. For example, if the extract can only be used for granulation later, it can be used directly without the need for membrane filtration, thus improving processing efficiency and ensuring better coordination between the units. The filtration mechanism is configured to include: The support frame 6210 is arranged in a cylindrical shape in space. The support frame includes a plurality of fixing rings 6211 arranged vertically in space. Each fixing ring is integrated into a single structure by a plurality of longitudinally arranged connectors 6212. A plurality of mounting holes 6213 are provided on the inner sidewall of the support frame. The mounting holes are provided on the inner sidewall of the connectors and fixing rings. Multiple mesh-type arc-shaped filter layers 6214 are arranged in a split configuration. Each filter layer has a fixing post 6215 and a fixing ring 6216 on its outer edge that mates with the mounting hole. The fixing post and fixing ring are used to make the edge of the arc-shaped filter layer more rigid, which facilitates installation and fixation. The free end of the fixing post is provided with at least two fixing claws 6217. The size of each fixing claw when it is open is larger than the diameter of the mounting hole, and the size when it is closed is the same as the diameter of the mounting hole. In actual application, the free end of each fixing claw is provided with a fixing part with an arc surface. The outer arc of each fixing part can form a small ball that is directly consistent with the mounting hole after it is spatially enclosed. The interior of each fixing part has a default slope to allow it to pass through the mounting hole better. Each fixing part is turned outward from the fixing claw so that after passing through the fixing hole, it can contact the hole wall of the mounting hole through the outward structure to fix the arc-shaped filter layer.

[0028] Working principle: In this solution, the filtration mechanism is assembled by passing the fixing claws on the free end of the fixed column through the mounting hole, and then using the outward-turned structure of the fixing claws to contact the hole wall of the mounting hole to fix the arc-shaped filter layer, thus obtaining the corresponding filtration mechanism. The filtration mechanism can use centrifugal dewatering or pressing to separate the residue and water, and complete the filtration operation. At the same time, multiple filter mechanisms with different pore sizes can be used continuously during use to accelerate filtration efficiency and filtration effect.

[0029] In the above technical solution, the discharge port of the crushing unit 5 is configured to be connected to the extraction module 62, and the two units are connected by a conveying device to achieve continuous production.

[0030] In the above technical solutions, such as Figure 1 , Figure 8 The harvesting unit 1 includes: Frame 10 with material hopper; A conveying module 11, installed on one side of the frame, is used to fix one end of the pepper branches before transporting them. The fixing function of the conveying module is to press the branches of the pepper bunch onto the conveyor belt, preventing the branches of the pepper bunch from shifting when pulling the branches with pepper leaves. This fixed conveying can be achieved by setting two conveying mechanisms opposite each other, and the fixed conveying is completed by designing the distance between the two. Alternatively, a clamp can be set on a single conveying mechanism to fix the branches. A feeding module I12 is located on the other side of the frame and is used to comb the clamped pepper branches from one end to the other. The feeding module II13 is located above the frame and on the discharge side of the conveying module. It is used to beat or shake the combed pepper branches. Since the structure of the feeding module II13 is existing technology, its structure and connection relationship will not be described. The conveying module is configured to include: a conveying mechanism 111 and a sorting belt 112 with a feeding side of the conveying mechanism.

[0031] Working principle: In actual use, the harvested pepper branches are placed on the sorting belt. The sorting belt is vibrated and / or conveyed by a conveyor belt / chain to send one end of the pepper branch into the fixed conveyor side of the conveying module for fixation. After being fixed, the pepper branch is conveyed forward by the conveying module to the position of the unloading module I12. The unloading module I12 sorts the pepper branch from one end to the other to separate the pepper fruit and pepper leaves from the branch during the sorting process. After separation, the pepper fruits and leaves fall into the hopper below, while the pepper branches that are still clamped move to the location of the feeding module II 13. When they reach the feeding module II 13, the pepper fruits and leaves that have not yet fallen from the pepper branches after being processed by the feeding module I 12 are processed by hitting or shaking so that they can be successfully separated from the branches and fall into the hopper below. In the above technical solutions, such as Figures 6-8 The feeding module I12 includes: The elastic belt, located inside the frame and close to the conveying module, is used to provide elastic guidance force to match the pepper branches with different shapes and structures, ensuring that the space is controllable. The metal plate 122, which is set behind the elastic band, is configured to be 0.25-1.5cm thick. It serves as a workbench to facilitate the combing operation of the comb plate 124. At the same time, its structure is also flexible to prevent damage to the comb plate 124. A conveyor belt 123 is installed on a metal plate, and comb plates 124 are installed on it at predetermined intervals. The comb plate 124 is provided with multiple large teeth 1241 at preset intervals, and multiple medium teeth 1242 are evenly distributed between adjacent large teeth 1241. Multiple small teeth 1243 are evenly distributed between the medium teeth 1242. The extension length of the large teeth 1241 is greater than the extension length of the medium teeth 1242, and the extension length of the medium teeth 1242 is greater than the extension length of the small teeth 1243. Through the cooperation of large teeth 1241, medium teeth 1242, and small teeth 1243 of different sizes and lengths, the branches can be combed in all directions by reaching different positions. For example, the large teeth 1241 can reach deeper and contact the bottom of the branch, while the medium teeth 1242 can comb the middle of the branch, and the small teeth 1243 can comb the upper part of the branch. At the same time, during the combing process, the pepper leaves can be separated into small parts so that the pepper leaves can be separated from the comb after rotation. In actual application, the density of the arrangement of teeth of different sizes varies. Each tooth has multiple closely arranged sharp corners on the side wall that mates with the adjacent teeth. The tooth groove formed by the adjacent sharp corners is arranged opposite or staggered with the sharp corners of the adjacent teeth. Through the design of the sharp corners, the front end can be separated and the fruit-shaped peppercorns can be pulled and separated at the rear end during the combing process, resulting in better combing effect and preventing the fruit from breaking.

[0032] In the above technical solutions, such as Figure 1 , Figure 6 , Figure 9 The stripping unit 2 is configured to include: The unloading module Ⅲ14 is located on the discharge side of the frame and is adjacent to the unloading module Ⅱ13; The hopper of the feeding module Ⅲ14 is spatially adjacent to the hoppers of the feeding module Ⅱ13 and the hopper of the feeding module Ⅰ12, and the bottom of the hopper and the hopper are respectively provided with inclined discharge channels. The feeding module Ⅲ14 is configured to include: Multiple clamps 141 are arranged vertically or horizontally in space. The inner sidewall of each clamp 141 is arranged in an arc shape, and multiple arc-shaped blades 1410 of different sizes are provided on the inner sidewall of each clamp 141. The different sizes of arc-shaped blades 1410 are used to match pepper branches of different diameters so that the processing effect meets the needs of use. The fixing member 142 integrates the clamps 141 on the same horizontal line into a single structure. It is used to integrate multiple clamps 141 into a single structure in space so as to facilitate the linkage control of the drive mechanism. A drive mechanism 143 for adjusting the spatial position of a fixed component.

[0033] Working principle: After being processed by feeding module II13, the pepper branches that are still clamped move to the position of feeding module III14. The drive mechanism first drives the clamp 141 to change its horizontal position so that the clamp 141 comes to the end of the pepper branch with the handle. The drive mechanism then adjusts the spatial height of the clamp 141 so that the multiple clamps 141 arranged vertically or horizontally in space are all in the closed state. The drive mechanism once again drives the clamp 141 to change its horizontal position, moving the clamp 141 from one end of the pepper branch with the handle to the other end. The arc-shaped blade 1410 inside the clamp 141 can separate the pepper thorns, twigs, leaves and other parts from the pepper branch along the outer skin. Finally, the waste flowing out from the stripping unit 2 may contain pepper branches. The pepper branches have no more effective components than pepper leaves and seeds. They can be further processed in the crushing module for crushing and / or fermentation, and then used as biofuel, organic fertilizer and other applications. This realizes the full material application in the pepper harvesting process. The drive mechanism at the end adjusts the spatial height of the clamp 141 again so that the multiple clamps 141 arranged vertically or horizontally in space are all in a separated state, completing one cycle operation.
