[0011] The following further details the specific embodiments of the utility model by describing the embodiments in conjunction with the drawings.

[0012] A rice crust processing device, as shown in the appendix Figure 1 shows, including a unit plate 10 for supporting the rice crust raw materials. Above the unit plate 10, there is a grinding disc group 20, which is composed of grinding discs 21 arranged at intervals, that is, a number of grinding discs 21 arranged at intervals form the grinding disc group 20. The rotation axis core of the grinding disc 21 is perpendicular to the upper plate surface of the unit plate 11. The bottom plate surface of the grinding disc 21 is arranged parallel and at intervals with the upper plate surface of the unit plate 10, and the arrangement interval between the two is adjustable. In this embodiment, the grinding surface of the grinding disc 21 is parallel to the upper plate surface of the unit plate 10. By adjusting the distance between the grinding disc 21 and the unit plate 10, the grinding and processing effect on the rice crust material can be adjusted.

[0013] When the grinding disc 21 grinds the material, a downward acting force perpendicular to the plate surface of the unit plate will be applied to the material and the unit plate 11. Therefore, in this embodiment, a support element 31 is provided below the unit plate 10 to ensure the grinding and processing effect. In this embodiment, the unit plate 10 is a linear displacement plate, that is, the unit plate 10 makes a linear displacement at the processing device. Therefore, the support element 31 is selected as a support roller and a support wheel. As shown in the appendix Figure 2 、 4 shows, the center of the back of the unit plate 10 is rotatably connected with a support wheel through a seat body 32. A support seat 33 is correspondingly arranged on the frame 40. The support wheel is placed on the support seat 33 and forms a rolling fit with the support seat 33. Further, as shown in the appendix Figure 2 shows, two support rollers are symmetrically arranged on both sides of the support wheel. The support rollers are rotatably connected to the frame 40 by the seat body 32. The bottom surface of the unit plate 10 presses against the roller surface of the support rollers, and the unit plate 10 forms a rolling fit with the support rollers. In other embodiments, only support rollers or support wheels or other support elements can also be used to cooperate with the frame 40 to realize the support of the unit plate 10.

[0014] Specifically, as shown in the appendix Figure 1 shows, the unit plate 10 is a linear displacement plate. The displacement direction of the unit plate 10 is parallel to its upper plate surface and perpendicular to the direction of its long plate edge. In order to ensure that all the materials spread on the unit plate 10 can be ground, the friction area of the grinding disc group 20 covers the material spreading area on the unit plate 10. In this embodiment, as shown in the appendix Figure 1 、 3 shows, at least two rows of grinding discs 20a are arranged at intervals in the advancing direction of the unit plate 10. The grinding discs 21 in each row of grinding discs 20a are arranged at intervals. The rotation axis cores of the grinding discs 21 in the same row of grinding discs 20a are located in the same plane perpendicular to the conveying direction of the unit plate 10. Further, as shown in the appendix Figure 3 shows, in this embodiment, the grinding discs 21 of two adjacent rows of grinding discs 20a are staggered in the direction perpendicular to the advancing direction of the unit plate 10. In this way, the grinding surfaces of the grinding discs 21 of two adjacent rows of grinding discs 20a have overlapping and non-overlapping areas, which can ensure the full grinding of the materials.

[0015] In this embodiment, the unit board 10 is fixedly connected to the conveying chain. The conveying chain of the unit board 10 rotates and displaces cyclically around the driving wheel and the driven wheel under the drive of the driving wheel. The grinding disc group 20 is arranged at the upper chain section where the conveying chain is horizontally arranged. The displacement direction of the unit board 10 at this position is consistent with the extending direction of the conveying chain, that is, it makes a linear displacement in the horizontal direction.

[0016] The raw material of the rice crust is cooked cereal grains, or a slurry or paste mainly composed of cooked cereal grains. In specific implementation, the unit board 10 supports the material and makes a linear displacement along with the conveying chain. The rotation direction of the grinding disc 21 is arranged at an angle with the displacement direction of the unit board 10. The grinding disc 21 rotates to polish the soft rice crust raw material, so that the soft cereal grains are kneaded or scraped by the grinding disc 21. In this way, the rice crust raw material becomes denser under the extrusion of the grinding disc 21 and the unit board 10. At the same time, the soft cereal grains are deformed or even broken under the action of the grinding disc 21, which can promote the gelatinization of starch in the cereal grains during the subsequent baking process and improve the taste of the finished rice crust.

[0017] The grinding area of the grinding disc 21 on the rice crust raw material spread on the linearly displaced unit board 10 is strip-shaped. After the unit board 10 displaces through the grinding disc group 20, there may be strip-shaped protrusions on the upper surface of the rice crust raw material supported thereon. To smooth the protrusions, a pressure roller 60 can be arranged downstream of the grinding disc group 20. The pressure roller 60 rolls the rice crust raw material polished by the grinding disc 21 to improve the flatness of the upper surface of the rice crust raw material. In addition, if the water content of the rice crust raw material spread on the unit board 10 is low, or it is necessary to add seasoning slurry to the rice crust raw material, a nozzle 50 can be arranged upstream of the grinding disc group 20. The nozzle 50 is communicated with the slurry source, and the spraying outlet of the nozzle 50 points to the unit board 10.

[0018] As shown in the attached Figure 1 、 2 As shown in the figure, a grinding disc mounting frame 70 is arranged above the frame 40. A grinding disc seat 71 is arranged on the grinding disc mounting frame 70. The upper seat body of the grinding disc seat 71 is rotationally matched with driving elements such as a motor. The lower seat body is in a sleeve shape. The connecting shaft / tube 22 fixedly arranged above the disc body of the grinding disc 21 is inserted into the lower seat body of the grinding disc seat 71 and forms a limiting and guiding fit with it in the direction perpendicular to the disc surface of the grinding disc 21, so as to realize the adjustment of the distance between the grinding disc 21 and the unit board 10.

[0019] Further as shown in the attached Figure 1As shown, a spray head 50 is installed on the upstream side of the frame body of the grinding disc mounting frame 70, and the spray outlet of the spray head 50 points to the plate surface of the unit plate 10 located in front of the grinding disc group 20. A pressure roller 60 is installed on the frame 40 downstream of the grinding disc mounting frame 70 through a pressure roller seat 61. The roller core of the pressure roller 60 is perpendicular to the advancing direction of the unit plate 10, and the roller pressing surface of the pressure roller 60 is parallel to the plate surface of the unit plate 10. Denote the distance between the grinding disc 21 and the unit plate 10 as d1, and the distance between the pressure roller 60 and the unit plate 10 as d2, then |d1 - d2| ≤ 2 mm.
