[0036] An air inlet 13 for connecting a refrigeration device is arranged on one side of the outer cylinder 1, so that cold air can be conveyed into the outer cylinder 1 to accelerate the solidification of the protein bar, and the nearly closed structure of the outer cylinder 1 also helps to gather the cold air, so as to ensure the cooling effect on the protein bar, and a wind deflector 14 is fixedly installed in the outer cylinder 1 and located on one side of the shower pipe 10 to block the shower pipe 10, so as to avoid the influence of cold air on the pouring of chocolate slurry on the protein bar blank.

[0040] When the slitting roller 6 is used to slit the pressed strip-shaped protein bar material, the protein bar material will be trapped in the empty space of the grid-shaped cutter on the slitting roller 6. With the rotation of the slitting roller 6, the roller shaft 602 constantly rolls and presses the top strip 601 at the bottom, so that the top strip 601 can push out the protein bar blank in the empty space of the grid-shaped cutter.

[0041] Through the above technical solution, the longitudinal slitting mechanism and the transverse slitting mechanism on the existing slitting equipment are integrated, the occupied space of the slitting mechanism is reduced, the compactness of the entire device is ensured, and the problem of easy material jamming in the empty space of the slitting roller 6 is solved through a simple structure.

[0042] Please refer to Figure 9 The net belt conveying mechanism 8 is composed of two conveying rollers rotatably installed in the outer cylinder 1 and a net belt sleeved on the two conveying rollers. One of the conveying rollers is in transmission connection with the slitting roller 6, and synchronous wheels are arranged on the shafts of the two. The two synchronous wheels are in transmission through a synchronous belt. The net belt is composed of a plurality of chain rods 801 and a metal net woven on the plurality of chain rods 801. The inner walls of the two sides of the outer cylinder 1 are provided with arc-shaped ring tracks 802. The two ends of the plurality of chain rods 801 extend into the two arc-shaped ring tracks 802 and are in sliding connection with the arc-shaped ring tracks 802, so as to ensure that the entire net belt conveying mechanism 8 can adapt to the structure of the outer cylinder 1 and ensure the stability of the net belt conveying mechanism 8.

[0043] Please refer to Figures 7 to 8The auxiliary material conveying mechanism is slidably arranged on the rotating drum 3 and comprises a retractable scraper 304 and a strip-shaped shell 301 capable of driving the scraper 304 to retract, the strip-shaped shell 301 is composed of a bottom shell and a top cover and is fixed by two bolt columns, the bottom of the scraper 304 extends into the strip-shaped shell 301 and is slidably connected with the strip-shaped shell 301, the scraper 304 is composed of a vertical plate at the top and a bottom plate at the bottom, the bottom plate is in the strip-shaped shell 301 and is slidably penetrated by the two bolt columns, so that the rotating drum 3 can stably convey the protein bar raw materials through the scraper 304 while the scraper 304 does not affect the pressing of the protein bar raw materials by the press roller 5 and the cutting of the protein bar raw materials by the cutting roller 6, two springs 305 are arranged in the strip-shaped shell 301, the two springs 305 are sleeved on the two bolts respectively, the top ends of the two springs 305 abut against the bottom of the scraper 304, so that the scraper 304 retracts into the strip-shaped shell 301 when subjected to external pressure, the two sides of the outer cylinder 1 are provided with convex ring-shaped sliding grooves 303, the convex parts of the convex ring-shaped sliding grooves 303 are located in the area of the feeding hopper 4 and the press roller 5, so that the scraper 304 does not automatically retract into the strip-shaped shell 301 when it is in the area, the two ends of the strip-shaped shell 301 are provided with sliding shafts 302, the two ends of the two sliding shafts 302 extend into the two convex ring-shaped sliding grooves 303 and are slidably connected with the two convex ring-shaped sliding grooves 303, so that the scraper 304 and the strip-shaped shell 301 automatically retract into the rotating drum 3 after leaving the area of the feeding hopper 4 and the press roller 5.

[0044] When the scraper 304 moves to the press roller 5, the press roller 5 presses the springs 305 and the scraper 304 descends to a certain extent, so that the protein bar raw materials between the two scrapers 304 are limited for better pressing and forming, and the normal rotation of the rotating drum 3 is not limited, and under the action of the sliding shaft 302 and the convex ring-shaped sliding groove 303, when the auxiliary material conveying mechanism leaves the convex area of the convex ring-shaped sliding groove 303 under the driving of the rotating drum 3, the scraper 304 retracts into the rotating drum 3 under the driving of the strip-shaped shell 301.

[0045] Through the above technical scheme, the rotating drum 3 can stably convey the raw materials falling from the feeding hopper 4 by means of the scraper 304, and the scraper 304 is not limited by the guide sieve plate 7 and the pouring pipe 10, so that the stable conveying of the protein bar raw materials by the whole rotating drum 3 is ensured.

[0046] The implementation principle of the protein bar food rotating processing line in the embodiment is as follows:

[0047] When deployed, the melted chocolate slurry is added to the material box 9, and the air supply pipe of the refrigeration equipment is connected with the air inlet 13.

[0048] When the protein bar is processed, the mixed protein bar raw material is transported into the feeding hopper 4, then the motor 2 is started, the motor 2 drives the rotating drum 3 to rotate counterclockwise and drives the raw material on the rotating drum 3 to move (when the rotating drum 3 rotates, the cutting roller 6 and the mesh belt conveying mechanism 8 are simultaneously driven to rotate clockwise), in this process, the compression roller 5 can compact the raw material, so that the raw material becomes a strip, and the cutting roller 6 can cut the raw material into small strips by synchronous rotation with the rotating drum 3, so as to form the protein bar blank (in this process, the cold air in the outer cylinder 1 can make the syrup in the protein bar blank solidify, so as to ensure the shaping of the protein bar), thereby completing the extrusion, cooling and cutting of the protein bar raw material;

[0049] Then the cut protein bar blank falls on the mesh belt conveying mechanism 8 through the two guide screens 7, the raw material scraps fall on the guide groove 11 through the screen holes on the guide screens 7 and are discharged, completing the raw material recovery;

[0050] When the protein bar blank is driven by the mesh belt conveying mechanism 8 to pass under the pouring pipe 10, the chocolate syrup discharged from the pouring pipe 10 coats the protein bar blank, then penetrates through the mesh belt conveying mechanism 8 and returns to the material box 9, and the process is repeated, so as to realize the coating work 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), then the processed protein bar is discharged through the discharge groove 12 under the conveying of the mesh belt conveying mechanism 8.

[0051] The above embodiments are only preferred embodiments of the present application, and cannot be used to limit the scope of protection of the present application, and any non-essential changes and replacements made by those skilled in the art on the basis of the present application are within the scope of protection of the present application.
