Description

Technical Field

[0001] This invention relates to the field of processing equipment technology, and more specifically, to a potato pulp and residue separation and processing device. Background Technology

[0002] In the potato starch processing, potatoes are crushed to form a pulp mixture, which needs to be separated to remove potato fiber residue, resulting in a starch-rich slurry. Existing potato pulp-residue separation equipment mainly includes a frame, a feeding crushing chamber, a horizontal cylinder, and a drive shaft. The horizontal cylinder contains a cylindrical screen frame, with a filter screen covering the outside. The crushed potato pulp enters the cylindrical screen frame, and under the agitation and pushing action of the drive shaft and its associated pushing structure, the starch slurry seeps through the filter screen, thus completing the pulp-residue separation operation.

[0003] In actual production, after the potato slurry seeps through the filter screen covering the outside of the cylindrical screen frame, the resulting slurry still contains some potato fiber or small clumps of residue. These impurities mixed into the starch slurry not only reduce its purity but also affect the quality of the finished starch product obtained from subsequent processing, thus requiring improvement. Summary of the Invention

[0004] The purpose of this invention is to provide a potato pulp residue separation and processing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A potato pulp and residue separation and processing device includes a frame, The crushing box is located at the rear of the frame. The top of the crushing box has a feeding port, and the front side wall of the crushing box has a port. The crushing component is rotatably mounted inside the crushing chamber and is used to crush potatoes fed into the crushing chamber into pulp. The connecting cylinder has one end extending into the crushing chamber from the port. The connecting cylinder has a feed inlet on the circumferential side wall inside the crushing chamber. The feed inlet is connected to the upper end of the crushing chamber. The crushed slurry enters the connecting cylinder through the feed inlet. The front baffle is located on the front side of the frame, and a slag outlet is provided on the side wall of the front baffle. The separation component is located between the front baffle and the connecting cylinder. The separation component is used to separate the potato residue and slurry that enter the connecting cylinder. The separated potato residue is discharged from the residue outlet. The horizontal cylinder is located between the front baffle and the crushing chamber. The horizontal cylinder includes two semi-cylindrical bodies, which are fastened together. After the two semi-cylindrical bodies are fastened together, a cavity is formed to accommodate the separation components. A slurry outlet pipe is provided on the outer wall of the lower semi-cylindrical body to discharge the separated slurry. The filter assembly is located below the horizontal cylinder and is used to filter the discharged slurry again.

[0006] Furthermore, the separation component includes a cylindrical frame disposed between the front baffle and the connecting cylinder. A drive shaft is rotatably disposed inside the cylindrical frame. One end of the drive shaft extends into the connecting cylinder and protrudes from the rear side wall of the crushing chamber, while the other end protrudes from the front baffle. Multiple sets of connecting plates are fixedly disposed on the drive shaft, and push plates are fixedly disposed on the connecting plates. The push plates are used to push the potato residue to the residue outlet for discharge.

[0007] Furthermore, the outer side of the cylindrical frame is covered with a filter screen, which allows the slurry to penetrate through the filter screen into the cavity of the horizontal cylinder, and finally be discharged outward through the slurry outlet pipe.

[0008] Furthermore, the pusher plates are arranged in a spiral inclination along the drive shaft axis, and several pusher plates are connected in sequence to form a continuous spiral pushing surface. The pusher plates rotate with the drive shaft to push the potato residue to the residue outlet.

[0009] Furthermore, the push plate is equipped with bristles that come into contact with the filter screen. The bristles rotate synchronously with the push plate and scrape the filter screen to keep the filter screen pores clear.

[0010] Furthermore, the filter assembly includes a receiving frame located below the horizontal cylinder. The bottom wall of the receiving frame has a square trough, and a filter cloth is provided in the square trough. The filter cloth is used to filter the slurry discharged from the slurry outlet pipe again.

[0011] Furthermore, support plates located on the frame are provided at the lower corners of the receiving frame. A lead screw is rotatably provided between the support plates on one side, and a guide rod is fixedly provided between the support plates on the other side. A movable frame is provided below the receiving frame. One end of the movable frame is slidably engaged with the guide rod, and the other end is threadedly engaged with the lead screw. A cleaning brush is fixedly installed on the movable frame. The cleaning brush is used to maintain the smooth flow of the filter cloth pores.

[0012] Furthermore, a guide frame is provided between the support plates, located below the receiving frame. The guide frame is inclined, and a slurry outlet is provided on the lower side wall of the guide frame, with a slurry outlet groove at the outlet. Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, by setting a filter assembly below the horizontal cylinder, allows the slurry, after initial separation by the filter screen, to undergo secondary filtration through the filter cloth. This further intercepts residual fine potato fibers and micro-clumps in the slurry, effectively reducing the impurity content in the slurry, improving the purity of the starch slurry, and reducing the mixing of impurities during the subsequent starch precipitation process. This improves the quality of the finished starch product and reduces the processing burden of the subsequent precipitation process.

[0013] 2. The present invention, by setting up a filter cloth cleaning mechanism consisting of a lead screw, a guide rod, a moving frame and a long strip cleaning brush, drives the lead screw to rotate, causing the cleaning brush to move back and forth along the lower surface of the filter cloth, which can unclog the filter cloth, ensure that the filter cloth maintains good liquid permeability, and reduce the intensity of manual cleaning.

Detailed Implementation

[0020] To further understand the content of this invention, a detailed description of the invention will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative and not limiting of the invention.

[0021] The following is in conjunction with the appendix Figures 1-5 This embodiment will be described in further detail.

[0022] Please see Figures 1-5 The potato pulp and residue separation and processing device in this embodiment includes a frame 100, which is a frame structure. The crushing box 101 is fixed to the rear side of the frame 100. The top of the crushing box 101 is provided with a feeding port as a channel for feeding potato raw materials. The front side wall of the crushing box 101 is provided with a circular port for connecting the connecting cylinder 102 structure.

[0023] The crushing assembly includes a spiked roller and a feeding roller, which are rotatably mounted in the internal cavity of the crushing chamber 101 via bearing seats. An external drive motor is connected to the rotating shaft of the crushing assembly for transmission. Potato raw materials are fed into the chamber through the feeding port, and the crushing assembly grinds and crushes the potatoes into a slurry-residue mixture. The connecting cylinder 102 is arranged horizontally, with its rear end penetrating through the circular port on the front side wall of the crushing chamber 101 and extending into the interior of the crushing chamber 101. The connecting cylinder 102 has an inlet on the circumferential side wall of the crushing chamber 101, which is connected to the upper crushing chamber inside the crushing chamber 101. The crushed slurry-residue enters the connecting cylinder 102 through the inlet.

[0024] A front baffle 103 is fixed to the front side of the frame 100, and a slag outlet 104 is provided on the side wall of the front baffle 103 as a channel for discharging potato residue. The separation assembly is assembled between the front baffle 103 and the connecting cylinder 102. A horizontal cylinder 105 is installed on the frame 100 between the front baffle 103 and the crushing box 101, and is composed of two symmetrically interlocked upper and lower semi-cylinders. After splicing, the interior forms a cylindrical sealed cavity for accommodating the separation assembly and collecting the separated slurry. A slurry outlet pipe 106 is provided at the lowest position of the lower semi-cylinder for discharging the separated slurry. The filter assembly is fixed to the area of ​​the frame 100 directly below the horizontal cylinder 105, and can perform secondary filtration on the separated slurry.

[0025] Please see Figures 1-3 In this embodiment, the cylindrical frame 200 is coaxially fixed between the front baffle 103 and the connecting cylinder 102. The drive shaft 201 is horizontally and coaxially inserted inside the cylindrical frame 200. The rear end of the drive shaft 201 passes through the cavity of the connecting cylinder 102 through a sealed bearing and finally extends out from the rear side wall of the crushing box 101. The extended end is connected to an external drive motor for driving. The front end of the drive shaft 201 passes through the front baffle 103 through a bearing and extends to the outside. Multiple sets of connecting plates 202 are fixedly installed on the drive shaft 201. Push plates 203 are fixedly installed on the connecting plates 202. The push plates 203 are used to push the potato residue to the residue outlet 104 for discharge.

[0026] Push plates 203 are uniformly arranged at a spiral inclination angle along the axial direction of the drive shaft 201. The inclination angle of a single push plate 203 is set to 15°-25°. Multiple sets of push plates 203 are connected sequentially along the length of the drive shaft 201, overlapping end to end, forming a continuous spiral pushing surface. The push plates 203 rotate synchronously with the drive shaft 201, and the spiral pushing surface rotates towards the slag outlet 104 near the front baffle 103. The potato residue can move forward under the action of the spiral thrust and is finally discharged from the slag outlet 104 outside the equipment.

[0027] Please see Figures 1-5In this embodiment, the entire outer circumference of the cylindrical frame 200 is fully covered with a filter screen 204. The starch slurry that seeps through the filter screen 204 can be directly collected in the bottom cavity of the horizontal cylinder 105 and finally discharged through the slurry outlet pipe 106.

[0028] Each push plate 203 is fixedly equipped with wear-resistant nylon bristles 205. The length of the bristles 205 is adapted to the gap between the push plate 203 and the filter screen 204, and the tips of the bristles 205 are always in close contact with the inner surface of the filter screen 204. The bristles 205 rotate synchronously with the push plate 203 and the drive shaft 201, and continuously scrape the surface of the mesh of the filter screen 204 during the rotation, so as to continuously ensure the screening permeability and screening efficiency of the filter screen 204.

[0029] Please see Figure 1 and Figure 4 In this embodiment, the receiving frame 300 is fixedly installed below the horizontal cylinder 105. Connecting columns 308 are fixedly installed on both sides of the receiving frame 300. The connecting columns 308 on both sides are fixedly connected to the front baffle 103 and the side wall of the crushing box 101, respectively. A square groove is opened on the bottom wall of the receiving frame 300. Food-grade filter cloth 301 is tensioned and laid inside the square groove. The mesh number of the filter cloth 301 is higher than that of the filter screen 204. The filter cloth 301 is fixed to the receiving frame 300 by pressure strips and bolts to ensure that the filter cloth 301 is flat, taut and wrinkle-free.

[0030] The slurry discharged from the slurry outlet pipe 106 falls onto the surface of the filter cloth 301, where it undergoes secondary filtration to intercept residual fine potato fibers and micro-clumps. The slurry, after secondary filtration, seeps downwards through the square trough. This secondary filtration by the filter cloth 301 further intercepts residual fine potato fibers and micro-clumps, effectively reducing the impurity content and purity of the slurry. This reduces the likelihood of impurities being introduced during subsequent starch precipitation, thereby improving the quality of the finished starch product and lessening the processing burden on subsequent precipitation steps.

[0031] Please refer to the figure. Figure 1 , Figure 4 and Figure 5In this embodiment, four support plates are correspondingly arranged at the four corners of the receiving frame 300, and the four support plates are symmetrically fixed to the frame 100 in pairs. One set of opposing support plates is connected to a lead screw 302 via bearings. One end of the lead screw 302 extends to the outside of the support plate and is connected to a drive motor to drive the lead screw 302 to rotate. The other set of opposing support plates is fixedly connected to a guide rod 303, which is arranged parallel to the lead screw 302. The guide rod 303 is provided with a first block 305, which has a through hole that slides with the guide rod 303. The first block 305 is fixedly connected to one side of the moving frame 304. The lead screw 302 is provided with a second block 306, which has a threaded hole that threadedly engages with the lead screw 302. The second block 306 is fixedly connected to the other side of the moving frame 304. By rotating the lead screw 302 forward and backward, the moving frame 304 can be driven to make horizontal reciprocating linear motion along the guide rod 303.

[0032] A long cleaning brush 307 is bolted to the upper surface of the movable frame 304. The top of the cleaning brush 307 fits tightly against the lower surface of the filter cloth 301, and the length of the cleaning brush 307 matches the width of the filter cloth 301, thus fully covering the filtration area of ​​the filter cloth 301. After each potato pulp separation operation, the drive motor connected to the lead screw 302 can be started. The lead screw 302 drives the cleaning brush 307 to move back and forth, clearing the mesh on the surface of the filter cloth 301. During the operation of the cleaning brush 307, water can be used to rinse the filter cloth 301 simultaneously, ensuring the permeability of subsequent filtration.

[0033] Please see Figure 1 , Figure 4 and Figure 5 In this embodiment, the guide frame 400 is inclinedly arranged and fixed between four support plates, and is located directly below the receiving frame 300 and the filter cloth 301. The guide frame 400 is inclined in a front-low and rear-high state. The lower front side wall of the guide frame 400 has a slurry outlet in the center. The slurry outlet is connected and fixed to the outside of the slurry outlet, and the slurry outlet 401 extends downward at an inclination, which can guide the filtered slurry to the subsequent slurry storage equipment.

[0034] In summary, the above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made within the scope of the claims of the present invention should be covered by the present invention.
