Description

Technical Field

[0001] The utility model relates to the technical field of food processing, in particular to a multi-stage grinding machine for konjac flour. Background Art

[0002] As the name suggests, konjac flour is a powder made from konjac as raw material. In the process of making konjac flour, grinding equipment is needed to grind the crushed konjac into powder. In this process, konjac flours with inconsistent particle sizes are mixed together; as a result, some konjac flours that have met the crushing requirements are still being ground, affecting the overall efficiency. Therefore, people have designed a multi-stage grinding device; through the setting of the screen, the konjac flour that meets the requirements of each level is discharged downward for processing at the next level, which can improve production efficiency.

[0003] For example, the patent with application number "CN202321658207.9" discloses a multi-stage grinder for konjac flour, including a processing tank, a top plate arranged at the top of the processing tank, and a pouring port opened on the top plate, and the grinder also includes: a filter plate, multiple filter plates are arranged in the processing tank, and the inside of the processing tank is divided into multiple grinding chambers; a grinding roller, multiple grinding rollers are respectively arranged on the upper surface of multiple filter plates; a driving unit, arranged on the top plate, and penetrated on multiple filter plates, and connected with multiple grinding rollers. When grinding, as long as the konjac component is less than the aperture of the current filter plate, it can fall on the next filter plate by itself, until grinding is completed by all filter plates, during which time konjac can be continuously fed, and the ground konjac automatically enters the next grinding chamber for grinding again, and will not be subject to the accumulation of konjac flour, and the entire konjac flour grinding time is greatly reduced.

[0004] The above scheme can significantly improve the grinding efficiency of konjac flour. However, the filter plate directly bears pressure, resulting in a large load and a short life. At the same time, konjac flour is easily accumulated at the edge. In addition, the feeding efficiency is low and the discharging is also troublesome. Utility Model Content

[0049] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0050] Reference Figure 1-10 A multi-stage konjac flour grinding machine comprises a cylindrical shell 1 which is opened at the top and the bottom, and a horizontal U-shaped base 2 is connected to the lower end of the cylindrical shell 1.

[0051] like Figure 1-2 As shown, the circular part of the base 2 overlaps and is connected to the cylindrical shell 1; at the same time, the circular part of the base 2 extends to one side to form a square shell part; the upper part of the square shell part is closed and the lower part is open; accordingly, a sliding plate 3 is obliquely arranged inside the base 2.

[0052] Furthermore, a vibration motor 31 is provided on the lower bottom surface of the sliding plate 3, so that the material can be discharged more smoothly.

[0053] Meanwhile, a multi-layer bucket-shaped sieve plate 4 is arranged inside the shell 1, so that the konjac flour is gathered in the middle position, avoiding the situation that the konjac flour is pushed to the periphery and a large amount of konjac flour is piled up and cannot be operated.

[0054] It can be understood that the aperture of the sieve plate 4 gradually decreases from top to bottom; the konjac flour is subjected to multi-stage grinding and screening operations.

[0055] Correspondingly, a main shaft 5 is rotatably arranged at the center of the cylinder shell 1 , and no less than three grinding rollers 6 are arranged on the main shaft 5 corresponding to the upper part of each layer of the sieve plate 4 ; during operation, the multiple grinding rollers 6 cooperate to grind the konjac flour.

[0056] It is understandable that the main shaft 5 needs to be powered; accordingly, after the lower end of the main shaft 5 passes through the slide plate 3, it is connected to the driving device.

[0057] Preferably, a pulley 51 is provided at the lower end of the main shaft 5 .

[0058] When in use, the konjac flour to be processed is added inwardly through the open space at the top, the opening is large enough, and the feeding is convenient; the konjac flour is crushed on each layer of the sieve plate 4 after being rolled by the grinding roller 6, and falls after screening to be ground at the next level; finally, it falls on the sliding plate 3 and is discharged outward.

[0059] In some embodiments, a raised seat 41 adapted to the main shaft 5 is provided at the center of the sieve plate 4 .

[0060] like Figure 5-6 The raised seat 41 strengthens the stability of the main shaft 5, and at the same time increases the matching surface with the main shaft 5, which can reduce the impact of konjac powder falling into the gap; at the same time, it also avoids more accumulation of konjac powder in the center position.

[0061] In some embodiments, an obliquely extending shaft 52 is fixedly disposed outside the main shaft 5 , and the grinding roller 6 is sleeved on the obliquely extending shaft 52 and rotates.

[0062] like Figure 7 As shown, each layer is provided with three obliquely extending shafts 52 , and each is matched with a grinding roller 6 .

[0063] In some embodiments, the grinding roller 6 includes: a spiral grinding roller 61, a convex ring grinding roller 62, and a smooth grinding roller 63. As shown in the figure, the three grinding rollers 6 have different operation modes and grinding effects, and the grinding effect is further guaranteed by matching each other.

[0064] The spiral grinding roller 61 is provided with spiral strips 611 on the outside of the roller body; while rolling, the konjac flour is also pushed to move along the spiral, thereby avoiding the problem of large lumps and parts that cannot be ground.

[0065] Furthermore, a plurality of notches 612 extending along the axial direction of the roller body are formed on the spiral strip 611 .

[0066] like Figure 8-9 In order to prevent the konjac flour from getting stuck in the spiral, the spiral is cut into multiple small segments by multiple through-cut notches 612, and the konjac flour can cross the notch positions. At the same time, sharp contact points are added after the notches are set, which can enhance the crushing efficiency.

[0067] Correspondingly, raised rings 621 are arranged at intervals outside the roller body of the raised ring grinding roller 62 .

[0068] like Figure 7 , 10 As shown; the raised ring 621 contacts the sieve plate 4 to grind the konjac flour; some larger konjac flour falls between the raised rings 621 and is squeezed and crushed.

[0069] Correspondingly, the outer diameter of the smooth grinding roller 63 is larger, and its outer ring surface is completely in contact with the sieve plate 4; while grinding itself, it can also level the uneven surface of the konjac flour produced by the spiral grinding roller 61 and the convex ring grinding roller 62, and has a good grinding effect.

[0070] In some embodiments, a plurality of triangular supports 7 are disposed around the bottom of the sieve plate 4 .

[0071] As shown in the figure; one long side of the triangular support 7 is fitted under the sieve plate 4 to increase the direct supporting surface; the other long side is fixed on the inner wall of the cylinder shell 1 at an angle downward to the outside to bear the pressure and lift up the sieve plate 4; under the action of the two, not only the supporting effect is reliable, but also the strength of the sieve plate 4 is improved.

[0072] Furthermore, a reinforcement ring 8 is provided below the sieve plate 4 .

[0073] As shown in the figure, the reinforcement ring 8 provides an annular reinforcement effect, so that the screen plate 4 has better deformation resistance.

[0074] When the utility model is used, the konjac flour to be processed is added from the upper part of the cylinder shell 1; the driving component is turned on to drive the main shaft 5 to rotate, and the grinding roller 6 starts to work as the main shaft 5 rotates; under the rolling and crushing of the grinding roller 6, the konjac flour reaching the corresponding particle size passes through the sieve plate 4 and falls into the next layer, and continues to be processed by the grinding roller 6 of the next layer; until the particle size meets the requirements, it falls to the sliding plate 3; the vibration motor 31 below the sliding plate 3 is operated, and the konjac flour is discharged outward along the sliding plate 3.

[0075] In the utility model, the upper part of the cylinder shell 1 is open, the opening is large enough, and the feeding is convenient; the sliding plate 3 at the lower part discharges the konjac powder outward, and the discharging is fast and convenient; the bucket-shaped screen plate 4 makes the konjac powder gather in the middle, avoiding the situation that a large amount of konjac powder is piled up on the periphery; the raised seat 41 is provided to strengthen the stability of the main shaft 5, and at the same time avoid the accumulation of more konjac powder in the center; the three grinding rollers 6 have different operation modes and grinding effects, and the grinding effect is further guaranteed by mutual matching; the triangular support 7 is arranged around the bottom of the screen plate 4, which not only has a reliable supporting effect, but also improves the strength of the screen plate 4; the reinforcing ring 8 is arranged below the screen plate 4 to provide a circumferential reinforcement effect, so that the screen plate 4 has better anti-deformation ability.
