Description

Technical Field

[0001] The invention relates to the technical field of food processing, and in particular to a protein bar food rotary processing line. Background Art

[0002] Protein bar is a convenient and fast nutritional supplement, mainly used to supplement protein and energy. It is generally in the shape of strips (bars). It is generally made of various grains and beans as the main ingredients with chocolate and other auxiliary ingredients. The processing steps of protein bars are generally divided into stirring (mixing various raw materials evenly), extrusion (pressing the mixed raw materials into strips), cooling (accelerating the solidification of the syrup inside the raw materials), cutting (cutting the entire compacted strip-shaped raw material into small strips), and coating (pour melted chocolate on the surface of the cut protein bar to form a chocolate shell).

[0003] At present, the entire processing line of protein bars is composed of different equipment (stirring and mixing equipment, conveying and pressing equipment, cooling equipment, conveying and slitting equipment, and mesh belt conveying and pouring equipment). The entire processing line takes up a large space and is not compact enough. Therefore, it is necessary to propose a protein bar food rotating processing line. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a protein bar food rotary processing line.

[0005] The present invention is implemented by the following technical scheme: an outer cylinder which is circular in shape and is provided with a feed hopper and a discharge trough, a rotating cylinder for conveying protein bar raw materials is rotatably installed in the outer cylinder, a pressing roller which cooperates with the rotating cylinder to press the raw materials is rotatably arranged in the outer cylinder, and a slitting roller with a grid-type cutter on the surface for cutting the raw materials into strips is rotatably arranged in the outer cylinder, a mesh belt conveying mechanism which can be adapted to the outer cylinder and a pouring pipe which can cooperate with the mesh belt conveying mechanism to pour chocolate coating on the protein bar are arranged in the outer cylinder, thereby integrating the functions of the processing equipment on the protein bar processing line into one.

[0006] As a further improvement of the above solution, the bottom end of the feed hopper extends into the outer cylinder and is close to the rotating cylinder, so as to evenly control the conveying amount of the raw materials by the rotating cylinder.

[0007] As a further improvement of the above scheme, two material guide screen plates with different heights and facing opposite directions are fixedly arranged in the outer cylinder between the slitting roller and the mesh belt conveyor mechanism, and a material guide trough is also arranged below the two material guide screen plates to screen out the raw material debris produced by slitting.

[0008] As a further improvement of the above solution, a material box for containing chocolate slurry is further provided at the bottom of the outer cylinder, and a connecting pipe is further connected between the material box and the pouring pipe.

[0009] As a further improvement of the above scheme, a plurality of top strips distributed in a ring shape are slidably arranged on the slitting roller, the bottoms of the plurality of top strips extend into the slitting roller, the tops of the plurality of top strips extend into the spaces of the grid-type cutter respectively, and a roller for squeezing the top strips is also arranged in the slitting roller, so as to eject the protein bar blanks trapped in the spaces of the grid-type cutter after slitting.

[0010] As a further improvement of the above scheme, the mesh belt conveying mechanism consists of two conveying rollers rotatably installed in an outer cylinder and a mesh belt sleeved on the two conveying rollers. The mesh belt consists of multiple chain rods and a metal mesh woven on multiple chain rods. Arc-shaped ring rails are provided on the inner walls of both sides of the outer cylinder. The two ends of the multiple chain rods extend into the two arc-shaped ring rails and are slidably connected thereto, thereby ensuring that the entire mesh belt conveying mechanism can adapt to the structure of the outer cylinder while ensuring its own stability.

[0011] As a further improvement of the above scheme, a plurality of auxiliary material-carrying mechanisms distributed in a ring shape are slidably arranged on the rotating drum, and the auxiliary material-carrying mechanisms include a scraper which can be retracted when pressed by an external force and a strip shell which can drive the scraper to retract and retract by itself. The bottom of the scraper extends into the strip shell and is slidably connected thereto, thereby ensuring that the protein bar raw materials can be stably transported through the scraper when the rotating drum rotates, and at the same time, the scraper will not affect the pressing of the protein bar raw materials by the pressing roller and the cutting of the protein bar raw materials by the cutting roller.

[0012] As a further improvement of the above solution, two springs are arranged in the strip shell, and the top ends of the two springs are against the bottom of the scraper, so that the scraper will retract into the strip shell when pressed by external force.

[0013] As a further improvement of the above scheme, convex annular grooves are provided on both sides of the outer cylinder, and the raised parts of the convex annular grooves are located in the area of ​​the feed hopper and the pressure roller. Sliding shafts are provided at both ends of the strip shell, and the two ends of the two sliding shafts extend into the two convex annular grooves respectively and are slidably connected thereto, so that the scraper and the strip shell will automatically retract into the rotating cylinder after leaving the feed hopper and the pressure roller area.

[0014] As a further improvement of the above solution, an air inlet for connecting to a refrigeration device is provided on one side of the outer cylinder, so that cold air can be transported into the outer cylinder to accelerate the solidification of the protein stick.

[0015] Compared with the prior art, the present invention has the following beneficial effects: By setting a circular outer cylinder, and setting a rotating cylinder, a pressing roller, a slitting roller, a mesh belt conveying mechanism and a pouring pipe and other structures inside the outer cylinder, the entire outer cylinder becomes a protein bar rotary processing line integrating extrusion, slitting, coating and other functions. Compared with the existing protein bar processing line, the functions of multiple different processing equipment and conveying equipment are integrated to form an integrated device that basically has the functions of the entire processing line, which greatly reduces the land occupation burden of the existing production line; By setting a slitting roller and setting an ejection mechanism composed of a top strip and a roller on the slitting roller, not only the longitudinal slitting mechanism and the transverse slitting mechanism on the existing slitting equipment are integrated, the space occupied by the slitting mechanism is reduced, and the compactness of the entire device is ensured, but also the problem of easy material jamming in the space of the slitting roller is solved through a simple structure; An auxiliary material conveying mechanism composed of a strip shell, a scraper and other structures is arranged on the rotating drum, and a sliding shaft, a convex annular slide groove, a spring and other structures are used to control the force lifting and self-lifting of the scraper. The rotating drum can not only stably convey the raw materials falling from the feed hopper with the help of the scraper, but also the scraper will not be restricted by the guide screen plate, the pouring pipe and other structures, thereby ensuring the stable conveying of the protein bar raw materials by the entire rotating drum.

[0018] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0019] Please combine Figures 1 to 11 The protein bar food rotary processing line includes: an outer cylinder 1 which is circular in shape and is provided with a feed hopper 4 and a discharge trough 12. The outer cylinder 1 is composed of a cylinder and a large end cover and a small end cover arranged at both ends of the cylinder. The feed hopper 4 is an extended structure, which can be used as a feed inlet. When a stirring structure and a sealing door structure are installed inside the feed hopper 4, it can also be used as a mixing box. The bottom end of the feed hopper 4 extends into the outer cylinder 1 and is close to the rotating cylinder 3, so as to evenly control the conveying amount of the raw material by the rotating cylinder 3; A material box 9 for holding chocolate slurry is also provided at the bottom of the outer cylinder 1. A leakage port is provided between the inner wall of the bottom of the outer cylinder 1 and the material box 9. A connecting pipe is also connected between the material box 9 and the pouring pipe 10. A heater and a delivery pump are also provided in the material box 9. One end of the connecting pipe is connected to the discharge port of the delivery pump, and the other end is connected to the pouring pipe 10. The heater is used to continuously heat the chocolate slurry to prevent it from solidifying, and the delivery pump is used to deliver the chocolate slurry. A rotating drum 3 for conveying protein bar raw materials is rotatably installed in the outer drum 1. The rotating drum 3 is hollowed out to reduce its overall weight. A motor 2 for driving the rotating drum 3 to rotate is arranged in the outer drum 1. The motor 2 and the rotating drum 3 are connected through a synchronous wheel and a synchronous belt transmission. A pressing roller 5 for cooperating with the rotating drum 3 to press the raw materials and a slitting roller 6 with a grid-type cutter on the surface for slitting the raw materials into strips are rotatably arranged in the outer drum 1. Hollow gears of the same size are arranged on the shaft of the slitting roller 6 and the rotating drum 3. The hollow gears are meshed to allow the two to rotate at the same speed, so that the pressed strip-shaped raw materials can be transported and cut at the same time. The outer cylinder 1 is provided with a mesh belt conveying mechanism 8 that can be adapted to the outer cylinder 1 and a pouring pipe 10 that can cooperate with the mesh belt conveying mechanism 8 to pour chocolate coating on the protein bar. The surface of the pouring pipe 10 is wrapped with a heat insulation layer, so that the chocolate slurry transported inside it will not be affected by the cold air and solidified, so that the functions of the processing equipment on the protein bar processing line are integrated into one; An air inlet 13 for connecting to a refrigeration device is provided on one side of the outer cylinder 1, so that cold air can be transported into the outer cylinder 1 to accelerate the solidification of the protein bar. In addition, the nearly closed structure inside the outer cylinder 1 also helps to gather cold air, thereby ensuring the cooling effect on the protein bar. A wind shield 14 is also fixedly installed in the outer cylinder 1. The wind shield 14 is located on one side of the pouring pipe 10 to block the pouring pipe 10 to prevent cold air from affecting the pouring of chocolate slurry on the protein bar blank.

[0020] Through the above technical solution, the entire outer cylinder 1 becomes a protein bar rotating processing line integrating extrusion, slitting, coating and other functions. Compared with the existing protein bar processing line, the functions of multiple different processing equipment and conveying equipment are integrated to form an integrated device that basically has the functions of the entire processing line, which greatly reduces the land burden of the existing production line.

[0021] Please combine Figure 5 and Figure 7 Two material guide sieve plates 7 with different heights and facing opposite directions are fixedly arranged in the outer cylinder 1 between the slitting roller 6 and the mesh belt conveyor mechanism 8. A material guide groove 11 is also arranged below the two material guide sieve plates 7 to screen out the raw material debris produced by slitting. The two material guide sieve plates 7 are made of food-grade elastic materials such as rubber, so that when the protein bar blanks fall onto the material guide sieve plates 7, a buffer effect can be exerted on the protein bar blanks to prevent the protein bar blanks from becoming scattered or damaged.

[0022] Please combine Figure 10 to Figure 11 , a plurality of top strips 601 distributed in an annular shape are slidably arranged on the slitting roller 6, the top strip 601 is composed of a bottom strip at the bottom and a plurality of T-shaped top frames arranged on the top of the bottom strip, the bottom strips of the plurality of top strips 601 all extend into the slitting roller 6, the T-shaped top frames on the top of the plurality of top strips 601 respectively penetrate the slitting roller 6 and extend into the spaces of the grid-type cutter, and a roller 602 for squeezing the top strip 601 is also arranged in the slitting roller 6, so as to eject the protein bar blank trapped in the spaces of the grid-type cutter after slitting; When the slitting roller 6 cuts the pressed strip-shaped protein bar raw material, the protein bar raw material will fall into the spaces of the grid-type cutter on the slitting roller 6. As the slitting roller 6 rotates, the roller 602 continuously rolls the top strip 601 at its bottom, so that the top strip 601 can push out the protein bar blank in the spaces of the grid-type cutter.

[0023] Through the above technical solution, not only the longitudinal slitting mechanism and the transverse slitting mechanism on the existing slitting equipment are integrated, reducing the space occupied by the slitting mechanism and ensuring the compactness of the entire device, but also the problem of easy material jamming in the space of the slitting roller 6 is solved through a simple structure.

[0024] Please combine Fig. 9The mesh belt conveying mechanism 8 is composed of two conveying rollers rotatably installed in the outer cylinder 1 and mesh belts sleeved on the two conveying rollers. One of the conveying rollers is connected to the slitting roller 6 by transmission. Both shafts are provided with synchronous wheels, and the two synchronous wheels are driven by a synchronous belt. The mesh belt is composed of multiple chain rods 801 and a metal mesh woven on multiple chain rods 801. The inner walls on both sides of the outer cylinder 1 are provided with arc-shaped ring rails 802. The two ends of the multiple chain rods 801 extend into the two arc-shaped ring rails 802 and are slidably connected thereto, so as to ensure that the entire mesh belt conveying mechanism 8 can adapt to the structure of the outer cylinder 1 and ensure its own stability.

[0025] Please combine Figures 7 and 8 The drum 3 is also slidably provided with a plurality of annularly distributed auxiliary material-carrying mechanisms, the auxiliary material-carrying mechanisms comprising a retractable scraper 304 pressed by an external force and a strip shell 301 which can drive the scraper 304 to retract by itself, the strip shell 301 is composed of a bottom shell and a top cover, the two being fixed by two bolt columns, the bottom of the scraper 304 extends into the strip shell 301 and is slidably connected thereto, the scraper 304 is composed of a top vertical plate and a bottom bottom plate, the bottom bottom plate is in the strip shell 301 and is slidably penetrated by two bolt columns, so as to ensure that the drum 3 can stably transport the protein bar raw materials through the scraper 304 when rotating, and at the same time, the scraper 304 will not affect the pressing of the protein bar raw materials by the pressing roller 5 and the cutting of the protein bar raw materials by the cutting roller 6, Two springs 305 are arranged in the shell 301, and the two springs 305 are respectively sleeved on the two bolts. The top ends of the two springs 305 are against the bottom of the scraper 304, so that the scraper 304 will retract into the strip shell 301 when it is pressed by external force. Both sides of the outer cylinder 1 are provided with convex annular grooves 303, and the convex parts of the convex annular grooves 303 are located in the area of ​​the feed hopper 4 and the pressure roller 5, so that when the scraper 304 is in this area, it will not retract into the strip shell 301 by itself. Both ends of the strip shell 301 are provided with sliding shafts 302, and the two ends of the two sliding shafts 302 extend into the two convex annular grooves 303 and are slidably connected thereto, so that the scraper 304 and the strip shell 301 will retract into the drum 3 by themselves after leaving the area of ​​the feed hopper 4 and the pressure roller 5. When the scraper 304 moves to the pressure roller 5, the pressure of the pressure roller 5 will adaptively squeeze the spring 305 and drop to a certain extent, thereby limiting the protein bar material in the area between the two scrapers 304 for better pressing and forming, and at the same time will not restrict the normal rotation of the drum 3. Under the action of the sliding shaft 302 and the convex annular groove 303, when the auxiliary material belt mechanism leaves the raised area of ​​the convex annular groove 303 under the drive of the drum 3, the scraper 304 is retracted into the drum 3 under the drive of the strip shell 301.

[0026] Through the above technical solution, the rotating drum 3 can not only stably transport the raw materials dropped from the feed hopper 4 with the help of the scraper 304, but also the scraper 304 will not be restricted by the structures such as the material guide screen plate 7 and the pouring pipe 10, thereby ensuring the stable transportation of the protein bar raw materials by the entire rotating drum 3.

[0027] The implementation principle of a protein bar food rotary processing line in the embodiment of the present application is: When deploying, add melted chocolate slurry into the material box 9, and connect the air supply pipe of the refrigeration equipment to the air inlet 13; When processing protein bars, the mixed protein bar raw materials are conveyed to the feed hopper 4, and then the motor 2 is started, and the motor 2 drives the rotating drum 3 to rotate counterclockwise and drives the raw materials falling on the rotating drum 3 to transfer (the rotating drum 3 will synchronously drive the slitting roller 6 and the mesh belt conveyor mechanism 8 to rotate clockwise when rotating). In this process, the pressing roller 5 can compact the raw materials to make them into strips, and the slitting roller 6 can cut the raw materials pressed into strips into small strips by rotating synchronously with the rotating drum 3 to form protein bar blanks (in this process, the cold air in the outer cylinder 1 can solidify the syrup in the protein bar blanks to ensure the shaping of the protein bar), thereby completing the extrusion, cooling and cutting of the protein bar raw materials; When the cut protein bar blanks subsequently pass through the two material guide screen plates 7 and fall onto the mesh belt conveyor mechanism 8, the raw material debris will pass through the sieve holes on the material guide screen plates 7 and fall onto the material guide trough 11 and be discharged therefrom, thus completing the raw material recovery; When the protein bar blanks pass under the pouring pipe 10 driven by the mesh belt conveyor mechanism 8, the chocolate slurry discharged from the pouring pipe 10 will cover the protein bar blanks, and then seep through the mesh belt conveyor mechanism 8 back to the material box 9, and circulate in sequence, thereby realizing the coating of the protein bar (in this process, the cold air in the outer cylinder 1 can make the coating on the surface of the chocolate bar solidify quickly), and then the processed protein bar is transported by the mesh belt conveyor mechanism 8 and discharged through the discharge trough 12.

[0028] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
