Pet food granulation production equipment

Abstract

The invention belongs to the technical field of pet food granulation, and particularly relates to pet food granulation production equipment. During granulation, powder in the stock bin enters the granulation groove firstly, when the pressing cylinder passes through the eccentric inner arc plate, the powder is extruded firstly, then the powder is extruded into the granulation groove through the feeding roller to complete granulation, and after the pressing cylinder passes through the eccentric inner arc plate, the powder is extruded into the granulation groove through the feeding roller to complete granulation. The contact area of the material particles and the granulation forming area is obviously reduced (the effective adhesion area is reduced by 60-70%), so that the material particles and the granulation forming area can be easily separated, and the problem of blockage is effectively solved.

Description

Technical Field

[0001] The invention belongs to the technical field of pet food granulation, and in particular relates to pet food granulation production equipment. Background Art

[0002] Young pets cannot eat larger pieces of food, so the food sold for young pets is usually in the form of small pellets. In the process of processing such food, the raw materials need to be processed into pellets.

[0003] Existing pet food granulation methods can be categorized into three types: roller compression granulation, roller crushing granulation, and extrusion granulation. Roller compression granulation uses a pair of rollers with semi-granular dies evenly spaced on their surfaces. The rollers rotate at constant speeds relative to each other, compressing the powdered material into granules as the dies close. To facilitate shaping, a granulating liquid is often added. Roller compression granulation is a direct granulation method, offering advantages such as fewer steps, higher throughput, and diverse, dense, and regular granule shapes.

[0004] However, in the existing roller die pressing granulation method, after the pet food raw materials are pressed into the molding chamber, the raw materials contain a certain amount of moisture, which leads to insufficient separation during continuous granulation, such as Figure 16 As shown in the figure, the pelletizing cavity is blocked and compacted, which makes it difficult to clean and affects the processing efficiency. Summary of the Invention

[0021] The other end of the dispersion shaft is fixed with an engaging sleeve, both ends of the engaging sleeve are toothed surfaces, and the outer circumferential sliding sleeve of the engaging sleeve is provided with a toothed part 1 and a toothed part 2, which are distributed on both sides of the engaging sleeve, and the side close to the engaging sleeve is the toothed surface;

DETAILED DESCRIPTION

[0045] The technical solutions in the embodiments of the present invention will be clearly and completely described 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 the embodiments.

[0046] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0047] Example 1

[0048] like Figure 1 、 Figure 2 、 Figure 12 As shown, a pet food granulation production equipment includes:

[0049] A silo 10, wherein bulk material parts 11 are installed in the silo 10;

[0050] The forming assembly includes a granulating roller 12 and a feeding roller 13 symmetrically distributed at the bottom of the silo 10. The feeding roller 13 and the granulating roller 12 rotate in opposite directions and are driven by gears. The gear of the granulating roller 12 is a gear ring with internal and external teeth. The inner side of the gear ring is engaged with a driving gear and a servo motor that drives the driving gear. A central shaft 14 is independently installed inside the granulating roller 12. The granulating roller 12 and the central shaft 14 are connected by a bearing. An eccentric inner arc plate 15 is arranged on the central shaft 14. Granulating grooves are distributed on the surface of the granulating roller 12. 16. A plurality of relatively sliding radial embracing members 17 are distributed circumferentially within the granulation groove 16, and an elastic member 18 is installed on the inner side of the plurality of radial embracing members 17. A pressure member 19 is sleeved on the outer side of one end of the plurality of radial embracing members 17 away from the granulation groove 16. The circumferential positions of the pressure member 19 and the eccentric inner arc plate 15 correspond to each other. When the pressure member 19 passes through the eccentric inner arc plate 15, the radial embracing member 17 is acted upon by the pressure member 19 to radially extrude the powder in the granulation groove 16, and after passing through the eccentric inner arc plate 15, the radial embracing member 17 is separated from the granule embryo by the elastic member 18.

[0051] During the specific implementation, the raw material powder of pet food is put into the silo 10, the bulk material part 11 disperses the raw material, and the feeding roller 13 is evenly distributed with axial edges. The function of the axial edges is to feed the powder to the granulation roller 12. The powder enters the granulation trough 16. When the pressure member 19 passes through the eccentric inner arc plate 15, it will act on the radial embracing member 17 to make it slide radially, thereby initially shaping the internal pellets. The final position of the radial embracing member 17 is the same size as the granulation trough 16, and it cooperates with the feeding roller 13 to continuously feed, completing the high-density pellet forming action. After the pressure member 19 is separated from the eccentric inner arc plate 15, the radial embracing member 17 is automatically reset under the action of the elastic member 18, and the pellets can be separated from the granulation trough 16. At the same time, the pressure member 19 is reset. Since the contact area of ​​the pellets with the shaping area is significantly reduced (the effective adhesion area is reduced by 60-70%), the pellets can basically be completely separated from the granulation trough 16.

[0052] Example 2

[0053] In the device, Figures 2 to 7 As shown, the inner side of the radial embracing member 17 is evenly provided with a mounting groove 171 and a guide groove 172, the elastic member 18 is installed in the mounting groove 171, and the end of the radial embracing member 17 away from the granulation groove 16 is provided with a pressure-bearing cone surface 173;

[0054] The pressure member 19 includes a granulation base plate 191 and a pressure cylinder 192. The granulation base plate 191 slides in the guide groove 172. A cross plate 193 is installed on the side of the granulation base plate 191 facing away from the granulation groove 16. The cross plate 193 is installed on the inner wall of the granulation roller 12. The end of the pressure cylinder 192 away from the granulation roller 12 is a spherical structure. A connecting rod 195 and a plurality of pressure petals 194 circumferentially distributed on the outside of the connecting rod 195 are installed in the pressure cylinder 192. The pressure petals 194 are fixed on the inner wall of the pressure cylinder 192 and a pressure cone 196 is arranged on the end close to the granulation groove 16. The connecting rod 195 passes through the cross plate 193 and is connected to the granulation base plate 191.

[0055] like Figure 6 and Figure 7 As shown, a radial slide groove 198 is arranged on the cross plate 193 for radial movement of the radial encircling member 17 relative to the granulation groove 16.

[0056] A gap is reserved between the end of the pressure petal 194 away from the granulation groove 16 and the root of the inner wall of the pressure cylinder 192, and a guide block 197 is slidably fitted in the gap. The guide block 197 is connected to the end of the connecting block away from the granulation bottom plate 191.

[0057] When the pressure cylinder 192 is in the action path of the eccentric inner arc plate 15, the pressure cylinder 192 acts on the pressure conical surface 196 of the internal pressure petal 194 on the pressure-bearing conical surface 173 of the radial encircling member 17. The radial encircling member 17 moves radially along the radial groove 198, and finally forms a cylindrical structure with the same size as the granulation groove 16, and the bottom is blocked by the granulation bottom plate 191. The guide block 197 can slide axially along the pressure cylinder 192 and can also ensure that the granulation bottom plate 191 slides radially relative to the guide groove 172. After the pressure cylinder 192 passes through the eccentric inner arc plate 15, the elastic member 18 will act on the radial encircling member 17 to reset, and the pressure cylinder 192 will also reset and return to its initial state. Here, the radial encircling member 17, the granulation groove 16 and the granulation bottom plate 191 are all made of hydrophobic and oleophobic materials or sprayed with such coatings on the surface.

[0058] Example 3

[0059] like Figures 8 to 11 As shown, in Example 2, in order to effectively reduce the adhesion between the pellets and the granulation bottom plate 191 and avoid the problem of rough surface on the bottom, which may easily cause powder during subsequent drying, an extrusion body 199 is provided in the guide groove 172;

[0060] The granulation bottom plate 191 includes a bottom plate body 1911 and a movable plate body 1912. The bottom plate body 1911 is constrained by the extrusion body 199 and can only slide radially relative to the radial embracing member 17. The movable plate body 1912 is connected to the connecting rod 195 and an outer top body 1913 is provided on the side facing the bottom plate body 1911. The outer top body 1913 can freely pass through the bottom plate body 1911 and an elastic body 1914 is provided between the bottom plate body 1911 and the movable plate body 1912.

[0061] When the radially embracing member 17 approaches radially for granulation, the extrusion body 199 constrains the bottom plate 1911 so that it can only slide radially relative to the radially embracing member 17, and at the same time, it acts to move the movable plate 1912 away from the bottom plate 1911, and the elastic body 1914 is deformed. When the radially embracing member 17 is reset under the action of the elastic member 18, the elastic body 1914 acts to reset the movable plate 1912, and at the same time, the outer top body 1913 extends outward to axially eject the pellets from the granulation trough 16. It should be noted here that the sum of the end surface areas of the outer top body 1913 accounts for 50%-80% of the end surface area of ​​the bottom plate 1911.

[0062] Example 4

[0063] In the device, Figures 13 to 15As shown, the bulk material part 11 includes a dispersion shaft 111 and a light rod 112, and both ends of the dispersion shaft 111 are movably mounted on the silo 10. Two groups of material-moving rods 113 are arranged on the dispersion shaft 111. The two groups of material-moving rods 113 are respectively located near the two ends of the dispersion shaft 111. A prescribed path and a bulk material body 114 moving along the prescribed path are distributed on the dispersion shaft 111 between the two groups of material-moving rods 113. The bulk material body 114 is slidably fitted on the light rod 112. The prescribed path can be a spiral structure distributed along the outer wall of the dispersion shaft 111, such as a groove or a convex body. The bulk material body 114 is provided with a corresponding structure adapted to the groove or the convex body to meet the requirement of relative sliding between the two.

[0064] A driving motor 115 is installed on the side of the silo 10 , and an output end of the driving motor 115 is connected to the dispersion shaft 111 .

[0066] A fixing sleeve 116 is fixed to the side wall of the silo 10. The fixing sleeve 116 is located at the end of the silo 10 facing away from the drive motor 115. A reversing member 117 is mounted on the fixing sleeve 116. A reversing sleeve 118 is fixed to the outside of one end of the dispersion shaft 111. Two sets of annular grooves 119 are distributed on the reversing sleeve 118. The annular grooves 119 and the reversing member 117 correspond to each other and fit together.

[0067] The other end of the dispersion shaft 111 is fixed with an engagement sleeve 120. Both ends of the engagement sleeve 120 are toothed surfaces. The outer circumferential sliding sleeve of the engagement sleeve 120 is provided with a toothed part 121 and a toothed part 2 122. The toothed part 121 and the toothed part 2 122 are distributed on both sides of the engagement sleeve 120, and the side close to the engagement sleeve 120 is a toothed surface. The toothed part 121 and the toothed part 2 122 rotate independently on the side of the silo 10.

[0068] A transmission gear 123 is installed at the output end of the driving motor 115. The transmission gear 123 is distributed between the toothed member 121 and the toothed member 2 122, and meshes with one of the toothed members to form a transmission fit.

[0069] The reversing member 117 includes a mounting hole arranged on the side wall of the fixing sleeve 116 , in which a pressing body 124 , an elastic body 125 and a pressing body 126 are installed. The pressing body 126 is used to squeeze the elastic body 125 to adjust the pressing force of the pressing body 124 .

[0070] After the gear 124 is engaged with the toothed part 122, the gear 121 is engaged with the engagement sleeve 120, thereby realizing the reverse movement of the dispersion shaft 111. In this way, the bulk material body 114 can be driven to move in a straight line along the light rod 112.

[0071] Example 5

[0072] In the device, Figure 1 As shown, the equipment also includes a conveying mesh 20, a cleaning piece 21 and a cleaning piece 22. The conveying mesh 20 is arranged below the forming component, the cleaning piece 21 is arranged at the tail of the conveying mesh 20, and the cleaning piece 21 is used to clean the pellet embryo. The cleaning piece 22 is arranged below the lower conveying mesh 20, and the cleaning piece 22 is used to clean the conveying mesh 20.

[0073] The cleaning part 21 includes a fixed plate 211 and a scraper plate 213 arranged on the inner side of the conveying mesh 20 away from one end of the silo 10. An adjusting screw 212 is installed on the fixed plate 211. A reversing plate 214 is rotatably installed on the end of the adjusting screw 212. The reversing plate 214 slides horizontally relative to the fixed plate 211. The scraper plate 213 is independently arranged below the conveying mesh 20.

[0074] The cleaning part 22 includes a flushing pipe 222 arranged above the lower conveying mesh 20, a cleaning brush plate 221 distributed below the lower conveying mesh 20, and a squeezing roller 223 distributed on the rear side of the flushing pipe 222.

The cleaning water outlets are arranged toward the lower conveying mesh 20. The squeezing roller 223 is used to squeeze the conveying mesh 20 to maintain the required moisture content.

[0075] In practice, the dry conveyor mesh 20 may adhere to the material when receiving it. Continuous adhesion will cause the surface of the conveyor mesh 20 to clump, and when the material is separated from the conveyor mesh 20, the adhesion will not easily fall off. The inventors use the flushing pipe 222 to flush the conveyor mesh 20 and process it with the squeezing roller 223, so that the conveyor mesh 20 is effectively wetted. It is then used to receive the material and easily separated from the conveyor mesh 20 at the reversing plate 214. The scraper plate 213 can complete the complete separation of the material (redundant design). It is then flushed through the flushing pipe 222. During the flushing, the cleaning brush plate 221 cleans the receiving surface of the conveyor mesh 20. The top surface of the cleaning brush plate 221 is a brush surface. The cleaning brush plate 221 is then processed by the squeezing roller 223 to obtain the required moisture content to ensure the wetting effect of the conveyor mesh 20. A receiving water tank is also provided below the flushing pipe 222 and the squeezing roller 223 to receive the flushing wastewater.
