Technical Field

[0001] The present invention relates to the technical field of pea protein production, and in particular to an adjustable material collecting device for pea protein production. Background Art

[0002] The adjustable collecting device for pea protein production is a specialized piece of equipment used in food industrial processing and intelligent manufacturing. It is designed for the efficient collection and conveying of pea protein powder. Integrated sensors and an automated control system monitor material conditions (such as moisture and bulk density) in real time, and intelligently integrate with the production line to ensure a stable and efficient collecting process. This modular device, compatible with food-grade materials and compliant with clean production standards, is a key technology for promoting intelligent pea protein processing and reducing manual intervention.

[0003] In conjunction with the patent with announcement number CN115608605B, a pea protein powder screening device is disclosed, including a screening assembly, which includes a turntable and a screening box. A number of connecting blocks are provided around the turntable. The screening box includes a box body, two top plates are slidably provided on the top surface of the box body, a connecting shaft is provided at one end of the box body, a bevel gear is provided on the connecting shaft, a threaded tube is rotatably provided at the other end of the box body, sliders are provided on the bottom surface of the top plate, rotating shafts are provided in the side walls of both sides of the box body, gears are provided on the rotating shafts, avoidance grooves are provided on the sliders, racks are provided on the side walls of the avoidance grooves, a belt is connected between the threaded tube and the rotating shaft, and a screw is sleeved inside the threaded tube. In this way, the invention can complete the screening of pea protein powder and the separate storage of protein powders of different diameters without stopping the machine, and can also realize automatic cleaning of the sieve holes, thereby improving the screening efficiency.

[0004] However, in the prior art, including the aforementioned patents, the long-term storage of protein powder in the partitions can cause the protein powder to adhere to the inner wall of the partitions in the presence of moisture or insufficient drying. Furthermore, since pea protein powder contains fat and is inevitably affected by microbial interference during the production process, the adhered protein powder will remain in the partitions for a long time, making it more susceptible to mold and deterioration. Even if the protein powder is scraped off, it will mix with normal protein powder, causing product quality problems. Summary of the Invention

[0039] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0040] like Figure 1-15 As shown, an adjustable material receiving device for pea protein production includes a hopper 1 driven to move vertically and a positioning cover 3 slidably sleeved thereon. A rotating rod 2 is rotatably provided in the hopper 1. The hopper 1 also includes a filling cylinder 6 for receiving protein powder, an umbrella cover 32 provided on the positioning cover 3, and a first spring 221 provided on the positioning cover 3 for maintaining the positioning cover 3 at a predetermined height.

[0041] The scraper 5 is rotatably arranged in the hopper 1, and comprises a fixed plate 54 and a rotating scraper 51 (such as a fixed plate 54) for scraping the inner wall of the hopper 1. Figure 9 As shown), the fixed plate 54 and the rotating scraper 51 enclose an inclined channel;

[0042] A separation chamber 41 is provided in the hopper 1, which is used to receive the material fed into the inclined channel, and a filter screen 42 is provided at the bottom of the separation chamber 41;

[0043] The rotating blade 43 is rotated in the separation chamber 41, and the hopper 1 is provided with a side outlet 11 communicating with the separation chamber 41;

[0044] The umbrella cover 32 is pushed by the filling cylinder 6 to connect the side outlet 11 with the outside.

[0045] Specifically, it also includes an inner cover 4 for separating the hopper 1 and the separation chamber 41. The area between the inner cover 4 and the inner wall of the hopper 1 is the separation chamber 41 (such as Figure 2 and Figure 4 The inner cover 4 is rotatably arranged in the hopper 1 and is fixedly provided with a triangular fixing seat, the triangular fixing seat is fixedly connected to the rotating rod 2, and the fixing plate 54 is fixedly connected to the triangular fixing seat, and the rotating scraper 51 is rotatably arranged on the triangular fixing seat (such as Figure 9 As shown), a guide groove 44 is provided on the triangular fixing seat (as shown Figure 5 shown).

[0046] Furthermore, it also includes a discharge barrel 12, a side outlet 11 is located on the discharge barrel 12, a side opening 31 is opened on the positioning cover 3, and the two ends of the first spring 221 are fixedly connected to the bottom end of the discharge barrel 12 and the bottom end of the inner wall of the positioning cover 3 (such as Figure 2 As shown), the positioning cover 3 is slidably sleeved on the outside of the discharge barrel 12, and the umbrella cover 32 is fixedly set on the positioning cover 3. An electric telescopic rod or a hydraulic rod can be used to drive the hopper 1 to move in the vertical direction, or other driving methods known to those skilled in the art can be used.

[0047] Further, by driving motor drive rotating rod 2 to rotate, thereby drive scraper 5 to scrape hopper 1 inner wall, the albumen powder of agglomeration is scraped off by rotating scraper 51, avoid the albumen powder of agglomeration to further deteriorate, agglomerate material will enter in inclined channel and finally enter in separation chamber 41 along guide groove 44, in this process, common agglomerate albumen powder rolls and disperses along inclined channel.Under default state, due to the provision of the first spring 221, the spacing of positioning cover 3 and discharging barrel 12 is fixed, now side opening 31 is positioned below side outlet 11, the two are staggered so that side outlet 11 is not communicated with the outside world, now agglomerate material stays in separation chamber 41, by filter screen 42, the albumen powder that part thereof has dispersed is filtered out. In addition to the ordinary agglomerated protein powder in the hopper 1, there are also some agglomerates caused by mold or deterioration. During the agglomeration process of this part of the protein powder, due to microbial contamination or fat oxidation, the protein denatures and forms irreversible lumps (polysaccharides and organic acids produced by mold metabolism combine with proteins to form a complex similar to "biological glue", which is difficult to dissociate after hardening). It is difficult to disperse, so the moldy protein powder agglomerates will be retained above the filter 42, that is, in the separation chamber 41 (such as Figure 4 shown).

[0048] During the filling process, it is necessary to drive the hopper 1 to move the positioning cover 3 downward (the two are connected by the first spring 221 to maintain a fixed distance), and cover the umbrella cover 32 above the filling cylinder 6, so that the port of the filling cylinder 6 is completely shielded by the umbrella cover 32 to prevent dust from rebounding. Then, the hopper 1 is further driven to drive the umbrella cover 32 to move downward, and at the same time, the port of the filling cylinder 6 pushes the umbrella cover 32 upward, thereby driving the positioning cover 3 to move upward, and the first spring 221 contracts in the axial direction, and makes the side outlet 11 correspond to the side opening 31. At this time, the side outlet 11 is connected to the outside world.

[0049] The rotating blade 43 is rotated (the specific principle will be explained later). During the rotation process, the blades of the rotating blade 43 will push the moldy protein powder lumps on the upper side of the filter 42 toward the circumference, and then make this part of the moldy protein powder roll to the outside through the side outlet 11 until it falls on the upper surface of the umbrella cover 32, thereby removing the moldy protein powder. The protein powder that has agglomerated due to moisture is also broken up by the rotating blade 43, so that this part of the protein powder can pass through the filter 42. At the same time, since the side outlet 11 is only open during the filling process, the moisture problem caused by long-term exposure to the outside world can be avoided. A protrusion for intercepting materials is fixed on the edge of the umbrella cover 32. The staff can then take out the intercepted moldy protein powder as a sample for research to understand what kind of microbial contamination it is, thereby reducing the corresponding microbial interference in the production process of pea protein powder and making more targeted protective measures.

[0050] In the above technology, the scraper 5 is used to scrape the inner wall of the hopper 1, and the agglomerated protein powder is scraped off by the rotating scraper 51. The characteristic of the moldy pea protein powder to produce lumps is utilized, and it is more difficult to be broken up than the agglomerated undeteriorated protein powder, and can be screened out by the filter 42. Finally, the rotating blade 43 is used to roll this part of the moldy protein powder onto the upper surface of the umbrella cover 32, so that the staff can obtain samples and understand the cause of the mold of the protein powder.

[0051] As an embodiment further provided by the present invention, a movable block 22 for sealing the port of the hopper 1 is slidably provided at the lower end of the rotating rod 2 .

[0052] Specifically, the movable block 22 is coaxially arranged in the discharge barrel 12, and the movable block 22 is a bucket-shaped structure with a larger upper portion and a smaller lower portion, corresponding to the shape of the inner wall of the port of the hopper 1, that is, the port of the discharge barrel 12, and the lower end of the movable block 22 extends to the bottom surface of the positioning cover 3 (such as Figure 2As shown in FIG. 1 ). During the filling process, the umbrella cover 32 is placed over the filling barrel 6, and then the hopper 1 is further driven to drive the umbrella cover 32 downward, so that the port of the filling barrel 6 is completely shielded by the umbrella cover 32. At the same time, the port of the filling barrel 6 pushes the umbrella cover 32 upward, thereby driving the positioning cover 3 and the lower end of the movable block 22 to move upward simultaneously. The first spring 221 contracts in the axial direction, and the gap between the movable block 22 and the port of the discharge barrel 12 increases, making the port of the discharge barrel 12 (i.e., the port of the hopper 1) unobstructed, and filling begins. The protein powder can only roll downward after the umbrella cover 32 completely closes the port of the filling barrel 6, reducing the problem of protein powder being blown away and overflowing by the falling airflow.

[0053] As another embodiment provided by the present invention, the positioning cover 3 also includes a fixing portion 33, and a plurality of radially sliding snap-in blocks 34 are arranged in a circumferential array on the fixing portion 33, and a plug 23 is movably provided on the port of the fixing portion 33 to slide with the snap-in block 34.

[0054] Specifically, the connection portion between the fixing portion 33 and the umbrella cover 32 is a conical surface with a larger upper portion and a smaller lower portion (e.g. Figure 2 As shown), the positioning cover 3 of the present invention can be applied to filling cylinders 6 with port diameters within a certain range. The plug 23 is slidably arranged on the movable block 22, and a second spring 231 is provided on the plug 23 to maintain a fixed distance with the movable block 22, and the first spring 221 is easier to contract than the second spring 231.

[0055] During the filling process, first, the fixing portion 33 is aligned with the opening of the filling cylinder 6, driving the hopper 1 to move downward. Through the connection of the first spring 221, the hopper 1 moves downward and drives the positioning cover 3 downward at the same time. The umbrella cover 32 covers the top of the filling cylinder 6, and then the hopper 1 is further driven to drive the umbrella cover 32 to move downward, so that the port of the filling cylinder 6 is completely covered by the umbrella cover 32, and the fixing portion 33 extends into the filling cylinder 6. The port of the filling cylinder 6 pushes the umbrella cover 32 upward. At this time, the positioning cover 3 drives the plug 23 to move upward, and the positioning cover 3 and the plug 23 are still kept in close contact. The plug 23 still blocks the port of the fixing portion 33. At the same time, the plug 23 drives the movable block 22 to rise through the support of the second spring 231. The first spring 221 contracts to the limit, so that the port of the discharge cylinder 12 is unobstructed (such as Figure 14 shown).

[0056] The hopper 1 is then driven downwardly, causing the clamping block 34 to be squeezed by the inner wall of the filling barrel 6. At the same time, the clamping block 34 supports the filling barrel 6 from the inside, and can perform centering and positioning for filling barrels 6 with a certain caliber range, thereby avoiding powder leakage caused by caliber mismatch. Multiple clamping blocks 34 move toward the center of the circle, and the ends of the clamping blocks 34 push the plug 23, causing the plug 23 to move upward relative to the fixed portion 33 and push the second spring 231. At this time, the plug 23 and the fixed portion 33 ports are staggered, and the powder enters the filling barrel 6 through the port of the positioning cover 3, so that the powder is always filled in the center position, making the filling barrel 6 more uniform.

[0057] As another embodiment provided by the present invention, the angle between the fixing portion 33 and the umbrella cover 32 is an acute angle, and the fixing portion 33 and the umbrella cover 32 enclose a semi-enclosed space.

[0058] Specifically, the cross section of the semi-enclosed space is as follows: Figure 2 As shown, the enclosure of the fixing portion 33 and the umbrella cover 32 can further improve the anti-puff effect during the filling process. Even if the protein powder flies under the blowing of the downward airflow, it will be intercepted by the umbrella cover 32 during the process of rising along the outer wall of the fixing portion 33, thereby reducing the overflow of the protein powder.

[0059] As another embodiment provided by the present invention, a locking block 24 is slidably provided at the bottom of the rotating rod 2 , and the umbrella cover 32 reaches a high position during the upward movement so that the locking block 24 is coupled with the rotating blade 43 .

[0060] Specifically, an auger 21 is slidably mounted on the rotating rod 2 and positioned within the discharge barrel 12. The upper end of the auger 21 is connected to the rotating rod 2, and the lower end is rotatably connected to the movable block 22. The auger 21 enables precise metering, and a locking block 24 is fixed to the auger 21. By default, the canopy 32 is in a low position. During the downward movement of the hopper 1, the port of the filling barrel 6 pushes the canopy 32 upward to a high position. At this point, the positioning cover 3 drives the block 23 upward. The block 23, supported by the second spring 231, raises the movable block 22, thereby driving the auger 21 and the locking block 24 upward for a distance.

[0061] The rotating leaf 43 is provided with a slot 431 corresponding to the locking block 24 (eg Figure 5 As shown, the locking block 24 rises and couples with the slot 431. Since both the locking block 24 and the auger 21 are slidably mounted on the rotating rod 2, the rotation of the rotating rod 2 drives the locking block 24 to rotate. Therefore, the locking block 24 simultaneously rises and rotates, facilitating alignment and coupling with the slot 431. After coupling, the locking block 24 drives the rotating blade 43 to rotate via the slot 431, eliminating the need for a separate drive mechanism to drive the rotating blade 43, thereby reducing costs.

[0062] As another embodiment provided by the present invention, it also includes a stopper 55 rotatably arranged on the fixed plate 54, which has an introduction station for introducing materials.

[0063] Specifically, a rotating shaft 52 is fixedly provided on the rotating scraper 51, and the rotating shaft 52 is rotatably provided on a triangular fixed seat (such as Figure 9 and Figure 10 As shown in FIG, wherein the fixed plate 54 is L-shaped, and a slide plate 56 is slidably provided on the long side of the fixed plate 54, and the short side of the fixed plate 54 is an arc-shaped structure that always closely contacts the edge of the rotating scraper 51. The first end of the rotating scraper 51 abuts against the inner wall of the hopper 1, and the second end is fixedly provided with a hook-shaped portion 53. The fixed plate 54 is also provided with an elastic member 57, and the deformation potential energy of the elastic member 57 causes the stopper 55 to abut against the rotating scraper 51 (as shown in FIG. Figure 11 As shown). The rotating scraper 51 is deflected by the material on the inner wall of the hopper 1. At this time, the rotating scraper 51 is deflected clockwise as a whole (as shown). Figure 12 As shown), the hook portion 53 swings and pushes the slide plate 56, the slide plate 56 approaches the stopper 55 and pushes the end of the stopper 55, so that the stopper 55 overcomes the elastic force of the elastic member 57 and deflects (as shown). Figure 12 As shown in FIG, the stopper 55 is in the introduction station and forms an introduction port between the stopper 55 and the rotating scraper 51. The material scraped off by the rotating scraper 51 enters the fixed plate 54 along the introduction port, thereby entering the inclined channel. By the provision of the stopper 55, the inclined channel is opened only when the inner wall material is scraped, so that other normal protein powders are prevented from entering the inclined channel. Even if normal protein powder is mixed in, it is a small amount, and these protein powders can re-enter the discharge barrel 12 through the filter screen 42.

[0064] As another embodiment provided by the present invention, a steel ball 432 is fixedly provided on the rotating blade 43 .

[0065] Specifically, the steel ball 432 is located at the end of the rotating blade 43, as shown in FIG. Figure 6 As shown, when the rotating blade 43 rotates, the steel ball 432 is driven to roll on the surface of the filter screen 42, thereby vibrating the filter screen 42 and shaking off the powder on the surface, thereby preventing the filter screen 42 from being blocked. The vibration of the filter screen 42 also accelerates the dispersion of ordinary agglomerated protein powder, further screening out moldy agglomerated protein powder.

[0066] Working principle: The rotating scraper 51 is deflected by the material on the inner wall of the hopper 1. At this time, the rotating scraper 51 is deflected clockwise as a whole (such as Figure 12 As shown), the hook portion 53 swings and pushes the slide 56, the slide 56 approaches the stopper 55 and pushes the end of the stopper 55, so that the stopper 55 deflects (as shown Figure 12 As shown), the stopper 55 is at the introduction station and forms an introduction port between the stopper 55 and the rotating scraper 51. The material scraped by the rotating scraper 51 enters the fixed plate 54 along the introduction port and then enters the inclined channel.

[0067] The agglomerated material will enter the inclined channel and eventually enter the separation chamber 41 along the guide groove 44. During this process, the ordinary agglomerated protein powder rolls and disperses along the inclined channel. At this time, the agglomerated material stays in the separation chamber 41, and the protein powder that has been dispersed is filtered out by the filter screen 42. The moldy protein powder agglomerates will be retained above the filter screen 42, that is, in the separation chamber 41 (such as Figure 4 shown).

[0068] During the filling process, first, the fixing portion 33 is aligned with the opening of the filling cylinder 6, driving the hopper 1 to move downward. Through the connection of the first spring 221, the hopper 1 moves downward and drives the positioning cover 3 downward at the same time. The umbrella cover 32 covers the top of the filling cylinder 6, and then the hopper 1 is further driven to drive the umbrella cover 32 to move downward, so that the port of the filling cylinder 6 is completely covered by the umbrella cover 32, and the fixing portion 33 extends into the filling cylinder 6. The port of the filling cylinder 6 pushes the umbrella cover 32 upward. At this time, the positioning cover 3 drives the plug 23 to move upward, and the positioning cover 3 and the plug 23 are still kept in close contact. The plug 23 still blocks the port of the fixing portion 33. At the same time, the plug 23 drives the movable block 22 to rise through the support of the second spring 231. The first spring 221 contracts to the limit, so that the port of the discharge cylinder 12 is unobstructed (such as Figure 14 shown).

[0069] At the same time, the side outlet 11 corresponds to the side opening 31. At this time, the side outlet 11 is connected to the outside world. During the rotation process, the blades of the rotating blade 43 will push the moldy protein powder lumps on the upper side of the filter 42 toward the circumference, and then make this part of the moldy protein powder roll to the outside through the side outlet 11 until it falls on the upper surface of the umbrella cover 32.

[0070] The hopper 1 is then driven downwardly, causing the clamping block 34 to be squeezed by the inner wall of the filling barrel 6. At the same time, the clamping block 34 supports the filling barrel 6 from the inside, and can perform centering and positioning for filling barrels 6 with a certain caliber range, thereby avoiding powder leakage caused by caliber mismatch. Multiple clamping blocks 34 move toward the center of the circle, and the ends of the clamping blocks 34 push the plug 23, causing the plug 23 to move upward relative to the fixed portion 33 and push the second spring 231. At this time, the plug 23 and the fixed portion 33 ports are staggered, and the powder enters the filling barrel 6 through the port of the positioning cover 3, so that the powder is always filled in the center position, making the filling barrel 6 more uniform.

[0071] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
