Description

Technical Field

[0001] The present invention relates to a food particle granulator, in particular to a food particle granulator applied in the field of food processing equipment. Background Art

[0002] At present, granulation technology has been more and more widely used in various industries such as medicine, food, building materials, chemical industry, metallurgy, etc. Among them, rotary food granulator is used in the pharmaceutical, food, granules, chemical industry, solid beverage and other industries to make the stirred materials into granules, especially suitable for materials with high viscosity. All parts of this machine that come into contact with the materials are made of stainless steel, with beautiful appearance, reasonable structure, high granulation forming rate, beautiful particles, automatic discharge, avoiding particle damage caused by manual discharge, and suitable for flow operation to obtain cylindrical particles. The aperture and opening rate of the screen mold have a great influence on the effect of extrusion granulation. The materials passing through the screen mold are easy to stick together and cause blockage, which will affect its production process.

[0003] In order to solve the above problems, the Chinese patent CN220464405U specification discloses a rotary granulator, including a main body, a granulation box is fixedly connected to the upper surface of the main body, and a stirring box is fixedly connected to the upper surface of the granulation box. This rotary granulator is provided with a first motor, a stirring rod, a fixed plate, and a first guide plate, which can stir the early materials to prevent blockage.

[0004] The specification of Chinese patent CN218609250U discloses a rotary extrusion granulator, which includes a shell, an extrusion barrel, an extrusion hole, and a feed hopper. A rotating shaft is rotatably connected in the extrusion barrel, a rotating barrel is rotatably sleeved below the rotating shaft, a pressing blade and a grinding knife are respectively provided on the top of the rotating shaft and the rotating barrel, and a blade in contact with the inner wall of the extrusion barrel is provided at the end of the grinding knife, which has the advantages of preventing materials from adhering to the barrel wall and improving the extrusion granulation efficiency.

[0005] The above methods all involve scraping or stirring the inner wall of the equipment. In actual situations, when the granulating cylinder of the rotary food granulator is operating, as the wet material is squeezed out of the annular screen, the self-rotating pushing blade shaft only contacts the inner wall of the annular screen. Material residue will appear on the inner wall of the pore area of ​​the annular screen. Once material residue occurs, the material discharge in this area will be slow. In addition, the wet material remaining in the sieve holes of the annular screen during the gap in the discharging process gradually dries up due to contact with the air, which will eventually cause blockage and affect the discharging efficiency of the granular finished product. Therefore, it is necessary to design a food granulator with anti-blocking function to solve the above problems. Summary of the invention

[0006] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that material residue will appear on the inner wall of the pore area of ​​the annular screen, resulting in slow discharge in this area. In addition, the wet material remaining in the sieve holes of the annular screen in the gap during the discharge process gradually dries up in contact with the air, which will eventually cause blockage and affect the discharge efficiency of the granular finished product.

[0007] In order to solve the above problems, the present invention provides a food particle granulator, including an equipment base, a granulation cylinder is fixedly connected to the upper end of the equipment base, an annular screen is fixedly connected to the outer end of the granulation cylinder, a feeding port is fixedly connected to the upper end of the granulation cylinder, a self-rotating pushing blade shaft is installed on the lower inner wall of the granulation cylinder, a self-rotating mixing upper shaft is installed on the upper end of the self-rotating pushing blade shaft, the self-rotating mixing upper shaft and the self-rotating pushing blade shaft rotate in opposite directions, the upper end of the self-rotating mixing upper shaft is fixedly connected to a ball storage upper column, the inner end of the ball storage upper column is filled with a plurality of anti-blocking magnetic balls, the anti-blocking magnetic balls fall to the outside of the ball storage upper column, and It passes through the annular screen and moves between the electric magnetic conveyor belt and the inclined unloading platform. The left end of the equipment base is fixedly connected with a unloading frame, which includes an inclined unloading platform. The left end of the inclined unloading platform is fixedly connected with a storage frame. The upper end of the unloading frame is fixedly connected with the electric magnetic conveyor belt. The left inner wall of the unloading frame is fixedly connected with a lower ball cross plate, and a ball storage bucket is engaged with the lower end of the lower ball cross plate. The anti-blocking magnetic ball moves between the electric magnetic conveyor belt and the inclined unloading platform, is adsorbed by the electric magnetic conveyor belt, and the anti-blocking magnetic ball cooperates with the lower ball cross plate to make the anti-blocking magnetic ball fall into the ball storage bucket.

[0008] In the above-mentioned food particle granulator, this scheme arranges a number of anti-blocking magnetic balls in the annular screen and scatters them into the granulation cylinder and squeezes them out of the annular screen together with the particles. The hard anti-blocking magnetic balls can push out the remaining materials in the sieve holes in the annular screen, avoiding the slow discharge phenomenon in local areas of the annular screen, which is beneficial to ensure the discharge efficiency of the granular finished products.

[0009] As a further improvement of the present application, a plurality of ball-lifting magnetic strips are fixedly connected to the upper end of the inclined unloading platform, and the ball-lifting magnetic strips cooperate with the anti-blocking magnetic balls.

[0010] As a further improvement of the present application, an electric guide shaft is fixedly connected to the upper side of the inner wall of the ball storage upper column, an inner hollow cylindrical piece is fixedly connected to the output end of the electric guide shaft, and a plurality of ball outlet grooves are provided on the lower side of the outer end of the ball storage upper column.

[0011] As a further improvement of the present application, the inner hollow cylindrical sheet is located on the inner side of the ball outlet slot, and the anti-blocking magnetic ball moves through the ball outlet slot to the outside of the ball storage upper column.

[0012] As another improvement of the present application, the outer end of the granulation cylinder is fixedly connected to an annular outer ring located directly above the annular screen, the four corners of the lower end of the annular outer ring are fixedly connected to a transverse electric slide, and the output end of the transverse electric slide is fixedly connected to a displacement plate.

[0013] As another improvement supplement of the present application, a visual analysis camera is fixedly connected to the middle of one end of the displacement plate close to the annular screen, and the multiple visual analysis cameras are all externally connected to a control terminal.

[0014] As another improvement supplement of the present application, one end of the displacement plate surface close to the annular screen is fixedly connected to a ball-guiding strong magnetic plate surface, and multiple ball-guiding strong magnetic plate surfaces are located outside the corresponding visual analysis cameras.

[0015] As another improvement of the present application, the self-rotating material mixing upper shaft, the self-rotating material pushing blade shaft and the electric magnetic conveyor belt are all externally connected to a driving device.

When the anti-blocking magnetic balls pass through the sieve holes in the annular screen, the hard anti-blocking magnetic balls can push out the remaining material in the sieve holes in the annular screen, thereby avoiding the slow discharge phenomenon in local areas of the annular screen, which is beneficial to ensuring the discharge efficiency of the granular finished products. The annular screen can be divided into four areas for monitoring with the visual analysis camera, and the magnetic force of the ball guide strong magnetic plate can be used to locally gather the anti-blocking magnetic balls in the annular screen, so that the anti-blocking magnetic balls can be as close to the abnormal area in the annular screen as possible for dredging operations, making the release area of ​​the anti-blocking magnetic balls more accurate.

[0028] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0029] The first implementation method:

[0030] Figure 1-2 5 shows a food particle granulator, including an equipment base 1, the upper end of the equipment base 1 is fixedly connected to a granulation column 2, the outer end of the granulation column 2 is fixedly connected to a ring-shaped screen 3, the upper end of the granulation column 2 is fixedly connected to a feeding port 4, the lower inner wall of the granulation column 2 is installed with a self-rotating pushing blade shaft 13, the upper end of the self-rotating pushing blade shaft 13 is installed with a self-rotating mixing upper shaft 14, the self-rotating mixing upper shaft 14 and the self-rotating pushing blade shaft 13 rotate in opposite directions, and the self-rotating mixing upper shaft 14, the self-rotating pushing blade shaft 13 and the electric magnetic conveyor belt 6 are all externally connected to a driving device.

[0031] Figure 6-7 It is shown that the upper end of the self-rotating mixing upper shaft 14 is fixedly connected to the ball storage upper column 15, and the inner end of the ball storage upper column 15 is filled with a plurality of anti-blocking magnetic balls 12. The anti-blocking magnetic balls 12 fall to the outside of the ball storage upper column 15 and pass through the annular screen 3 and move to between the electric magnetic conveyor belt 6 and the inclined unloading platform 10.

[0032] Figure 1-46 shows that the left end of the equipment base 1 is fixedly connected to a feeding frame 5, the feeding frame 5 includes an inclined feeding platform 10, the left end of the inclined feeding platform 10 is fixedly connected to a storage frame 11, the upper end of the feeding frame 5 is fixedly connected to an electric magnetic surface conveyor belt 6, the left inner wall of the feeding frame 5 is fixedly connected to a lower ball horizontal plate 7, the lower end of the lower ball horizontal plate 7 is engaged with a ball storage bucket 8, the anti-blocking magnetic ball 12 moves between the electric magnetic surface conveyor belt 6 and the inclined feeding platform 10, is adsorbed by the electric magnetic surface conveyor belt 6, and the anti-blocking magnetic ball 12 cooperates with the lower ball horizontal plate 7 to make the anti-blocking magnetic ball 12 fall into the ball storage bucket 8.

[0033] Figure 3 , 7 It is shown that a plurality of ball-lifting magnetic strips 9 are fixedly connected to the upper end of the inclined unloading platform 10, and the ball-lifting magnetic strips 9 cooperate with the anti-blocking magnetic balls 12. When the anti-blocking magnetic balls 12 follow the material particles to be transmitted to the bottom of the electric magnetic conveyor belt 6 on the inclined unloading platform 10, a plurality of ball-lifting magnetic strips 9 are arranged on the inclined unloading platform 10. The ball-lifting magnetic strips 9 and the anti-blocking magnetic balls 12 are mutually repulsive magnetic surfaces. The anti-blocking magnetic balls 12 that come into contact with the ball-lifting magnetic strips 9 will be lifted a certain distance due to the mutual repulsive force, which is beneficial to ensure the efficiency of the anti-blocking magnetic balls 12 adhering to the electric magnetic conveyor belt 6 and avoid omissions.

[0034] Figure 6-7 It is shown that an electric guide shaft 16 is fixedly connected to the upper side of the inner wall of the ball storage upper column 15, and an inner hollow cylindrical piece 17 is fixedly connected to the output end of the electric guide shaft 16. A plurality of ball outlet grooves 18 are provided on the lower side of the outer end of the ball storage upper column 15, and the inner hollow cylindrical piece 17 is located on the inner side of the ball outlet grooves 18, and the anti-blocking magnetic ball 12 moves to the outside of the ball storage upper column 15 through the ball outlet grooves 18.

[0035] Figure 1-7As shown, in this scheme, the wet food powder raw material is put into the granulation cylinder 2 through the feeding port 4, and the self-rotating pushing blade shaft 13 and the self-rotating mixing upper shaft 14 rotate in positive and negative directions respectively. The self-rotating pushing blade shaft 13 makes the food powder raw material fit and scrape the inner wall of the annular screen 3 and squeeze it out of the annular screen 3, so as to complete the preparation of the granular finished product. During the operation of the granulation cylinder 2, a ball storage upper column 15 filled with a plurality of anti-blocking magnetic balls 12 is arranged in the middle of the annular screen 3. The ball storage upper column 15 can use the electric guide shaft 16 to drive the inner hollow cylindrical piece 17 to move upward, so that the ball outlet groove 18 is exposed, and the anti-blocking magnetic balls 12 therein are scattered into the granulation cylinder 2, and follow the material body to flip in the granulation cylinder 2 and finally squeeze the anti-blocking magnetic balls 12 out of the annular screen 3 by the self-rotating pushing blade shaft 13. When the anti-blocking magnetic balls 12 pass through the sieve holes in the annular screen 3, the hard anti-blocking magnetic balls 12 The residual material in the sieve holes in the annular screen 3 can be pushed out to avoid the slow discharging phenomenon in the local area of ​​the annular screen 3, which is beneficial to ensuring the discharging efficiency of the granular finished product. At the same time, when the anti-blocking magnetic ball 12 is discharged together with the material body, it can slide on the inclined unloading platform 10 in the unloading frame 5 by gravity, and an electric magnetic surface conveyor belt 6 close to the material body is arranged on the inclined unloading platform 10. The electric magnetic surface conveyor belt 6 can adsorb the anti-blocking magnetic ball 12 outside the electric magnetic surface conveyor belt 6 by magnetic force and separate it from the finished material particles. The finished material particles are finally stored in the material storage frame 11. When they are collected on the surface of the electric magnetic surface conveyor belt 6 by magnetic force, they pass through the lower ball horizontal plate 7 on the left side of the electric magnetic surface conveyor belt 6. The anti-blocking magnetic ball 12 on the electric magnetic surface conveyor belt 6 can be intercepted and scraped off by the lower ball horizontal plate 7, and collected in the ball storage bucket 8 for the staff to backfill to the ball storage upper column 15 for circulation.

[0036] The second implementation method:

[0037] Figure 1 , 8 -9 shows that the outer end of the granulation cylinder 2 is fixedly connected to an annular outer ring 21 located just above the annular screen 3, and the four corners of the lower end of the annular outer ring 21 are fixedly connected to a transverse electric slide 25, and the output end of the transverse electric slide 25 is fixedly connected to a displacement plate 23, and the middle part of the end of the displacement plate 23 close to the annular screen 3 is fixedly connected to a visual analysis camera 24, and multiple visual analysis cameras 24 are all externally connected to a control terminal, and the end of the displacement plate 23 close to the annular screen 3 is fixedly connected to a ball-guided strong magnetic plate 22, and multiple ball-guided strong magnetic plates 22 are located on the outside of the corresponding visual analysis cameras 24. During the visual detection process, the visual analysis camera 24 converts the captured target into an image signal through the image capture device, and then transmits it to the image processing system in the control terminal, and converts it into a digital signal based on pixel distribution, brightness, color and other information, and the image processing system can perform various operations on these signals to extract the characteristics of the target, and then judge whether there is abnormal discharge according to the judgment result.

[0038] Figure 1 , 8 -9 shows that a plurality of transverse electric chutes 25 are arranged on the outer upper side of the annular screen 3. The visual analysis camera 24 outside the transverse electric chutes 25 can divide the annular screen 3 into four areas for monitoring. When it is detected that the discharge speed of the local area is significantly slowed down and the discharge volume is reduced, the transverse electric chute 25 can drive the corresponding displacement plate 23 to move to the area close to the annular screen 3 for a few seconds, and utilize the magnetic force of the ball-guiding strong magnetic plate 22 to locally gather the anti-blocking magnetic balls 12 in the annular screen 3, so that the anti-blocking magnetic balls 12 are as close to the abnormal area in the annular screen 3 as possible for dredging operations, so that the delivery area of ​​the anti-blocking magnetic balls 12 is more accurate, and the corresponding displacement plate 23 needs to be withdrawn to the outside before the anti-blocking magnetic balls 12 are squeezed out to avoid the anti-blocking magnetic balls 12 being adsorbed on the ball-guiding strong magnetic plate 22.

[0039] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
