[0001] DESCRIPTION

[0002] Trivalve pod shelling module, a shelling machine comprising it, and a shelling process

[0003] OBJECT OF THE INVENTION

[0004] The present invention falls within the agricultural and food sector, describing seed shelling. Specifically, the present invention aims to provide a means capable of shelling moringa pods quickly, easily, and efficiently; and which can be scaled up as needed.

[0005] STATE OF THE ART

[0006] The fruit of the moringa tree is a pod, similar to that of legumes, three-valved and triangular in shape. Those of Moringa oleifera contain winged seeds, which are loosely attached to the valves.

[0007] Moringa seeds yield an oil of similar quality to olive oil. Its use has not become widespread due to the cost of the traditional, manual method of harvesting the seeds. This technique involves a person twisting the pod to open it along the suture between the valves. Once open, a finger is inserted through the opening and pushed forward, all the way to the end, while the other hand holds the pod. The seeds, pushed by the finger, are released and fall out.

[0008] Shelling moringa seeds by hand is a tedious, slow, and repetitive task that can lead to fatigue, physical discomfort, injuries, and infections. Shelling one kilogram of moringa seeds requires about fifteen minutes of manual labor and another five minutes of rest. Consequently, the cost of producing the seeds is high. This situation was already documented in ancient texts, which is why moringa cultivation did not flourish despite the quality of the oil.

[0009] Automating the shelling process would lower the cost of the seeds and could make moringa represent the dry tropics what the olive tree represents the Mediterranean. If the assembly were carried out using field equipment, the volume of material transported would be reduced, resulting in significant cost savings. In terms of volume, five sacks of pods are equivalent to one sack of seeds.

[0010] Several records of moringa-specific shelling machines have been located. For example:

[0011] Invention BR102017001992A2, “Seed and pod shelling device”, a device for shelling Moringa oleifera seeds is described. The device is capable of performing a mechanical compression process by bringing the seeds into contact with two parallel flat bases of the device. Furthermore, the movement of an upper movable base of the machine also provides the shearing mechanism, which allows the broken shells to be separated from the compressed seeds due to the friction generated by the movement.

[0012] Utility model CN204697864U, “Horseradish tree seeds peeling device”, is a device for peeling moringa pods and seeds. From the inlet hopper, two rollers rotating in the same direction and positioned a certain distance from an inclined wall break the pods and hull the seeds. Two screening lines and fans separate the hulls from the peeled seeds.

[0013] On the other hand, the knife technique is used with legumes when the pods are green. In these cases, the knife is used to cut them linearly along the suture line of the valves, thus creating an opening through which the green beans will emerge more easily.

[0014] There are inventions relating to the use of blades, where said blades are intended to perform the household task of peeling green pea pods without having to open the shells with the thumbnail.

[0015] Examples of this type of solution include registration US2616434, which describes a handle with a blade at its end that allows the pods to be cut safely and the peas to be easily extracted.

[0016] Additionally, patent US2807267 proposes a manual device for shelling peas, into which the pods are inserted through a hole. The hole is located at the end of a handle and contains a sharp blade to open the pods linearly, and spring-loaded fingers to guide the pod's seam toward the blade.

[0017] A variant of this solution can be seen in the small household appliance for peeling peas or broad beans, Robito pod from Pelamatic SL (https: / / pelamatic.com / products / robito-vaina).

[0018] In 2014, the article Komolafe, CA, Ikubanni, PP, Okonkwo, CE, Ajao, FO, Alake, AS, & Olayanju, TMA (2020). “Performance evaluation and optimization of a Moringa oleifera depodding machine: A response surface approach”. Heliyon, 6(2). describes a prototype, called the Moringa Pod Stripper, for separating the seeds from the moringa pods. The system used is similar to that of log splitters, in which a hydraulic cylinder pushes the log against a splitting element, a wedge, opening it in two. Two parallel rollers are positioned on a base tray, sending the pods toward the splitting element. Before reaching the element, two blades are positioned, one located on the tray and the other, opposite it, on a frame anchored to the tray. As the pods pass over the blades, they are cut in two. After hitting the splitting element, the pods open and some seeds separate.Seeds and pods fall into a secondary shelling system.

[0019] Invention ES0134380, "Machine for shelling peas and the like," describes the use of blades at the end of rotating fingers to cut the edges of pea pods before they pass between two parallel rollers. Meanwhile, invention ES2003747A, "Apparatus for shelling broad beans," describes a device with very sharp, laminar prongs that make longitudinal incisions in the broad bean pods before they come into contact with a pair of shelling rollers.

[0020] None of these records describe a device that efficiently separates moringa seeds, reducing the cost of manual shelling and avoiding side effects on people's health.

[0021] Therefore, there is a need for developments in the moringa seed shelling sector that improve the separation of the seed from the pod. SUMMARY OF THE INVENTION

[0022] The invention arises from the need to reduce the cost of manual shelling and avoid its adverse health effects. In one aspect, the invention relates to a shelling module for trivalve pods. Examples of this type of pod include the moringa tree, both the Moringa oleifera species and other species of the same genus with similar, trivalve, triangular-shaped pods.

[0023] This type of shelling device features a frame that defines an inlet for closed pods and two outlets: one outlet for open pods and one outlet for seeds, already separated from the open pod.

[0024] Between the closed pod inlet and the two module outlets, the shelling module according to the present invention is located, which also comprises a sheller, a feeder and a pod drag system, supported on the frame.

[0025] The feeder is located connecting the closed pod inlet to the thresher. The feeder includes a pod guide. This pod guide is configured to be contacted by a three-valved or triangular pod with one of its side edges facing the thresher, while the opposite side, facing this edge, is oriented towards the pod feed system of the module. The guide directs the edge until it makes contact with the blade of the thresher.

[0026] On the other hand, the thresher comprises a first zone, or opening zone, and a second zone, or separation zone.

[0027] The first zone, or opening zone, comprises a blade and a wedge. The thresher blade is configured to cut an edge of a pod. Following the blade is a wedge, configured to separate and create an opening between the two valves adjacent to the edge recently opened by the blade. The second zone, or separation zone, comprises a thresher element or finger, designed to simulate a user's finger during manual threshering. The thresher element is configured to penetrate the opening created by the wedge, contacting and separating the seeds from the pod and sending them to a seed collection channel, which is configured to send the separated seeds to the seed outlet.Lateral guides, positioned parallel to the walls of the wedge, ensure that the pods are properly opened and that the threshing element is centered with respect to the line of seeds. Pods that are not straight tend to shift to one side, hindering the threshing process. Thanks to these guides, the pods are forced into the correct position towards the threshing element.

[0028] Finally, the thresher module includes a pod drive system, located opposite the feeder and the thresher. This drive system comprises an input roller with a contact surface. The contact surface is configured to grip a side face of a pod from the feeder and push the pod toward the thresher. Additionally, the contact surface is configured to adjust its position relative to the thresher. Similar to the thresher, the drive system includes an open pod channel configured to send a shelled pod to the open pod outlet of the thresher module.

[0029] In a second aspect, the invention relates to a shelling machine comprising at least one shelling module as previously described. In a further aspect, the invention relates to the process of shelling three-valved pods, such as moringa pods, to obtain the seeds from the pods. This shelling process is carried out linearly, placing the three-valved pods in a V-shape, and opening them with a blade and a wedge. With the pods open, the shelling element penetrates the opening and separates the seeds from the pods, resulting in the collection of the seeds. The pods are then ejected from the rear.

[0030] The objective of the invention is to perform an effective shelling of trivalve pods, such as those of moringa: quickly and easily, without damaging them, separating the seeds from the husks in a single operation and overcoming the complications posed by the triangular shape of the pods and the light weight of the seeds. Thanks to the present invention, in this process, human intervention is limited to feeding the machine, thus reducing the possibility of error and human risk.

[0031] This module is scalable, according to needs. In larger and higher-capacity equipment, the modules are mounted in parallel to form the thresher machine.

[0073] DETAILED DESCRIPTION OF THE INVENTION

[0074] In a first aspect of the invention, a moringa pod shelling module is described.

[0075] As can be seen in Figure 1, the three-valve pod shelling module comprises a frame (100) defining a closed pod inlet (001), an open pod outlet (002) and a seed outlet (003).

[0076] Unlike other known solutions, the shelling module according to the present invention further comprises a feeder (200), a sheller (300), and a drive system (400), supported on said frame. The feeder (200) is located connecting the closed pod inlet (001) to the sheller (300). Said feeder (200) comprises a pod guide (201). Said pod guide (201) is configured to be contacted, in use, by a triangular pod oriented with one of its lateral edges facing the sheller (300) and the opposite face, lateral to said edge, facing the pod drive system (400).

[0077] The thresher (300) comprises a first zone, or opening zone, and a second zone, or separation zone.

[0078] The opening zone comprises a blade (301) configured to, in use, cut an edge of a sheath, and a wedge (302), following the blade (301), configured to separate and create an opening between the two valves adjacent to the edge newly opened by the blade (301).

[0079] The separation zone comprises a thresher element (306) configured to penetrate the opening generated by the wedge (302), contacting and separating the seeds from a pod; and a seed channel (307), which connects the thresher (300) with the seed outlet (003).

[0080] The pod drag system (400), located opposite the thresher (300), has an attack roller (403) comprising a side surface configured to make contact with a side face of a three-valve pod, grip it and push the pod towards the thresher element (306), and an open pod channel (409) configured to send a thresher pod to the open pod outlet (002).

[0081] The threshing module according to the present invention can be presented individually, for small family farms, or with several modules arranged in parallel, in larger and higher-capacity equipment, for larger farms. Thus, in a second aspect, the invention relates to a threshing unit comprising at least one threshing module.

[0082] Thus, thanks to this solution, a safe and efficient seed collection procedure for trivalve pods can be carried out. The procedure comprises the following steps.

[0083] - place a closed pod on the pod guide (201) - correct the orientation of the closed pod so that one edge of the three-valve pod faces the blade (301) of the thresher (300), and the opposite face of the three-valve pod faces the drive roller (403) of the drive system (400),

[0084] - cut with the blade (301) the facing edge of the trivalve sheath,

[0085] - make an opening with the wedge (302) through the cut made in the trivalve sheath,

[0086] - penetrate the opening with a threshing element (306),

[0087] - separate the seeds from the pod, and

[0088] - collect the separated seeds.

[0089] The process involves making a longitudinal cut in the pod, followed by opening it with a wedge (302), positioned immediately after the blade, which passes through the groove created by the cut. This separates the pod's valves, exposing the seeds to the threshing element (306), which separates the seeds from the pod and allows them to fall into a container below via the seed collection channel (307). The threshed pods are then expelled through the pod channel (409).

[0090] In one particular embodiment, the frame of the shelling module is a fixed frame (100). Specifically, the frame (100) is a fixed element that serves as a base, supporting the feeder (200), pod drive system (400), and sheller (300). The frame (100) may comprise two solid side panels (102), so that a user of the device cannot accidentally access elements of the device.

[0091] This fixed frame (100) houses the open pod outlet (002) on one side and the seed outlet (003) on the other. Thus, in a particular embodiment, the area below the threshing element (306) has an open space next to the seed channel (307), which allows the seeds to fall freely into a container.

[0092] In one particular embodiment, the fixed frame (100) includes a space configured to mount, either directly or supported by another structure, the drive element that actuates the rotating shaft of the rollers in the pod drive system (400). This drive element can be an electric motor or a manually operated mechanical system, such as a simple crank or pedal. In one particular embodiment, the threshing module further includes a pivoting frame (401). This pivoting frame (401) is associated with the frame (100) and is configured to support the pod drive system (400) and allow it to tilt about the pivot axis (406).

[0093] In one specific embodiment, the pivoting frame (401) comprises a parallelepiped frame formed by at least two flat surfaces (402). These surfaces are preferably symmetrical and parallel.

[0094] In a further embodiment, the shafts of the rollers in the pod drive system (400) of the threshing module are mounted on these flat surfaces. In one particular embodiment, the input roller (403) includes an associated output roller (405). Thus, in a further particular embodiment, the input roller (403) and the output roller (405) are mounted between the two flat surfaces, resulting in parallel axes of rotation aligned on their axes.

[0095] In the specific case of using a sprocket (408) and chain (407) drive, the connection between the input and output shafts (404, 406) is made outside the pivoting frame (401). The distance between the shafts is determined by the minimum space required for proper seed evacuation, the size of the sprockets (408), and the chain pitch (407).

[0096] The tilting movement of the pivoting frame (401) is limited by a lower stop that prevents the drive roller (403) from contacting other elements of the module. This stop may be equipped with a damping spring. The clearance of the roller base must allow for easy insertion of the sheaths when they come into contact with the first roller (403).

[0097] In the case of a module comprising a single drive roller (403), said roller can be mounted on a pivoting frame (401), similar to the one described, in which the output roller (405) is missing, being replaced, for example, by the use of a sliding surface (106). In a preferred embodiment, the sliding surface (106) has a smooth surface.

[0098] Alternatively, the thresher module may comprise a frame (100) where the tray comprising it is a floating tray (103). The result of employing a floating tray (103) is the ability to control the distance between the thresher (300) and the pod drive system (400). An example of a floating tray (103) is a frame tray comprising a spring system (105) supported on a fixed base of the frame (104). This embodiment may also be configured with different embodiments of the pod drive system (400). Thus, the pod drive system (400) may comprise a roller assembly (input roller assembly (403) - output roller assembly (405)) or an assembly consisting of an input roller (403) and a slide (106).

[0099] As shown in Figure 1b, the thresher (300) is located downstream of the feeder (200). Additionally, Figure 2 shows how the thresher (300) is configured to be mounted on the frame (100).

[0100] The blade (301) is configured to receive the sheath pushed by the attack roller (403) and cut the lower edge of the sheath that has been exposed to the blade (301).

[0101] The wedge (302) separates and opens the freshly cut pods. The wedge (302) has a cross-section of an elongated isosceles triangle with a base similar in size to the threshing finger. In one particular embodiment, the wedge (302) may include lateral guides (303) parallel to it, forming a channel or path for the open pods (304) to facilitate the proper movement of the freshly opened pods toward the threshing element. That is, for controlled opening of the pods, two lateral guides (303) are arranged parallel to the walls of the wedge (302), leaving a path (304) along which the separated pods will move. In one particular embodiment, the lateral guides (303) may be a square rod with sides less than 1 cm.

[0102] The threshing element (306), whose function is to simulate a finger used during manual threshing, comes into contact with the seeds, detaching them from the pods. In one particular embodiment, the threshing element is positioned centrally behind the wedge (302), by means of an extension rod (305) from the tray (101), at a distance that allows the seeds to fall freely. The threshing element (306) must be able to easily enter the opening left by the wedge (302) in the pod once it has been cut.

[0103] In one particular embodiment, the threshing element (306) has a thumb-like shape. The upper end of the finger-shaped threshing element (306) should be close to the inside of the opposite face, the side opposite the cut edge, without touching it. A screw and locknut system can be used to adjust the height of the threshing element (306) for threshing.

[0104] In a particular embodiment, the feeding system or feeder (200) is mounted, directly or indirectly, on said frame.

[0105] As indicated, the feeder (200) comprises a pod guide (201). In a particular embodiment, said pod guide (201) has two surfaces in the pod support area in a V shape such that the pods contact them with one edge facing the thresher (300), located at the height of the vertex of the V, and the opposite side face of the pod is oriented towards the pod drive system (400).

[0106] Thus, in one particular embodiment, the pod guide (201) is designed so that the triangular pods enter the thresher (300) supported on one of their edges and with the opposite face substantially horizontal. This side face is presented to the pod drive system (400), in particular, to the drive roller (403).

[0107] Additionally, the placement of the pods on the guide can be done manually, in small farms, or automated, using conveyor belts (202) and turning guides (204), in large farms.

[0108] As shown in Figure 3, the pod guide (201) can be a tilting guide. Such a tilting guide is a type of pod guide (201) that can be used in thresher modules to increase the module's automation. In the tilting guide, at least one of the pod contact surfaces is displaceable by at least an angle of 50°. e with respect to the horizontal, forming a V between the two surfaces of the support area of ​​the sheath guide (201). The result of the displacement of at least one of the surfaces of the support area is the correction in the orientation of the trivalve sheath.

[0109] Thus, a pod, initially contacting the guide by resting one side face on the guide's support area, is displaced and positioned so that it contacts one side face on each of the two surfaces of the pod guide's support area (201), such that the edge between these two side faces faces the blade (301) arranged in the thresher (300). Alternatively, at least one of the surfaces of the pod guide's support area (201) has a warped profile that, starting approximately from the horizontal, ends symmetrically with respect to the other surface, in order to cause the pods to change position from resting on one face to resting on one of the edges, adopting the V-shaped position equivalent to the final position of the turning in a turning guide.

[0110] The drag system (400) consists of at least one attack roller (403) located at a certain height above the feeder (200) and thresher (300).

[0111] In one particular embodiment, the output roller (405) has a tilting pivot axis (406). By having a tilting pivot axis (406), a user can adjust the height of the input roller (403) relative to the feeder (200) and the thresher (300).

[0112] In one particular embodiment, the drive roller (403) comprises a gripping adhesion system integrated into its surface. This gripping adhesion system acts on the horizontal face of the sheath and pushes it towards the threshing system.

[0113] To facilitate the correct operation of the threshing element (306), the pod, driven on its upper surface by the drive roller (403), is sent towards the open pod outlet (002), with guide elements or means in between. These guide means can be: fixed and smooth, for example, using a slide (106), or movable, such as the exit roller (405), which regulates its position relative to the threshing element (306), preventing it from colliding with said element (306).

[0114] For its part, the pod drag system (400) comprises an open pod channel (409) that allows the easy evacuation of the pods to the outside once they have been shelled.

[0115] In one particular embodiment, the drive system (400) includes a second roller or discharge roller (405). This roller is similar to the drive roller (403) and is located a certain distance above the threshing element (306). Its function is to assist in threshing and to expel the processed pods to the outside of the module through the pod channel (409). In a further particular embodiment, both rollers are mounted on the pivoting frame (401). Additionally, they can be connected by a sprocket (408) and chain (407) system.

[0116] Specifically, for sanitary reasons and to avoid contact with the sheaths, the chain (407) is mounted on the outside of the pivoting frame (401). It may be protected by a safety housing so that a user does not have direct access to these connecting elements. The output shaft (406) is the drive shaft for the output roller (405). This output shaft (406) receives the motion from the drive mechanism and is also the axis on which the pivoting frame (401) pivots. For this purpose, the bushings or bearings of these elements are mounted on the frame (100).

[0117] Alternatively, the rollers (403, 405) can be joined by a belt, which must be equipped with a gripping system. In this case, the chain (407) of the previously described joining system could be omitted.

[0118] As shown in Figures 4 and 5, the pod drive system (400) may include a slide (106). The slide (106) comprises a fixed, smooth surface configured to contact the pod during its shelling in contact with the shelling element (306). It may be arranged in place of the output roller (405).

[0119] On the other hand, in machines with several modules in parallel, as described in a second aspect of the invention, the connection between the modules can be made by means of their respective output shafts (406). Thus, a threshing machine can range from a single output shaft (406) common to all modules to one that is divided and connected into as many parts as there are modules in the threshing machine.

[0120] In a single-module, manually fed shelling machine, the frame (100) is extended, for example, by using a tray (103) to allow the mounting of the pod guide (201) that supports the pods.

[0121] In a threshing machine with more than one module, the feeding of the modules can be automatic. Specifically, feeding can be carried out by means of a conveyor belt (202), in which case the feeding system is mounted on the conveyor belt structure (202) and will contain as many modules or lines as the width of the conveyor belt (202) allows. The drive shaft (406) of the modules can be single, common to all “n” lines; split, for independent modules; or mixed, joining several blocks of several modules on the same machine. Figure 6 shows a threshing machine comprising four threshing modules and four turning guides (204), arranged on a common conveyor belt (202). The turning guides (204) are floating and are mounted on a structure (205) attached to the conveyor belt structure (203) by means of anchor points (206).

[0122] The feeding system of a steam-capture machine may additionally include a receiving hopper, not shown in the figure. This hopper is configured to receive the pods to be shelled and distribute them along channels to each shelling module.

[0123] Following the receiving hopper is the conveyor belt (202), which contacts and transports the pods, resting on one of their sides, and brings them closer to the shelling module, passing them through the pod guide (201). As described above, there are variations of the pod guide (201) used, enabling pods to be fed into the sheller without the need for user interaction.
