This structure can well ensure the purity of the processed food and avoid food being contaminated by heavy metals and the like. Although the above structure has certain guarantees in terms of safety, there are also some disadvantages. First, the cost of each part made of food-grade stainless steel materials is high. Second, the maintenance cost is high. When a part is damaged during use or cannot meet the crushing particle size requirements due to excessive wear, the part needs to be replaced as a whole. Summary of the Utility Model
[0004] In view of the problems existing in the above background art, the utility model provides a novel crushing structure and a food processing device applying the same, which can not only reduce the manufacturing cost but also facilitate maintenance.
[0005] The technical solution adopted by the utility model to solve the above technical problems is as follows:
[0006] A crushing structure includes a crushing wall and a crushing roller. The crushing roller rotates inside the crushing wall to cooperate with the crushing wall to crush materials. The crushing roller includes a roller main body and a plurality of stainless steel grinding heads. The stainless steel grinding heads are detachably mounted on the outer periphery of the roller main body. The outer periphery of the roller main body has mounting platforms corresponding to the stainless steel grinding heads for mounting each stainless steel grinding head. The roller main body is composed of an aluminum core and a stainless steel shell. The stainless steel shell wraps around the outside of the aluminum core. The aluminum core has a core main body and a plurality of protruding parts distributed on the outer periphery of the core main body. The inner surface of the stainless steel shell includes a plurality of concave cavities corresponding to the protruding parts.
[0007] Preferably, in the crushing structure as described above, the positions of the protruding parts and the concave cavities exactly correspond to the positions of the mounting platforms on the outer periphery of the roller main body for mounting the stainless steel grinding heads.
[0008] Preferably, in the crushing structure as described above, the composite mode of the aluminum core and the stainless steel shell is inlay casting composite.

[0033] The following will describe the exemplary embodiments of the present disclosure in more detail with reference to the drawings. It should be noted that these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art. The present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein.
[0034] Embodiment 1
[0035] As Figures 2 to 5 shown, this embodiment provides a crushing structure that can be used in food processing equipment to crush materials by mechanical force or the synergistic action of mechanical force and air flow.
[0036] Similar to the prior art, the crushing structure of this embodiment includes a crushing wall 1 and a crushing roller 2. The crushing roller 2 rotates inside the crushing wall 1 to cooperate with the crushing wall 1 to crush materials. In food processing equipment, the above-mentioned crushing structure is connected to the equipment rotating shaft through the central shaft hole 4 and the keyway 3 on the surface of the shaft hole, and rotates driven by a motor. This is the prior art and not the focus of the present invention, so it will not be introduced in detail.
[0037] As the first improvement to the prior art, the crushing roller 2 of this embodiment includes a roller main body 21 and a plurality of stainless steel grinding heads 22. The stainless steel grinding heads 22 are detachably installed on the outer periphery of the roller main body 21 and can be installed by fasteners (not shown in the figure). As can be seen from a plurality of drawings, the outer periphery of the roller main body 21 has a mounting table corresponding to the stainless steel grinding heads 22 for installing each stainless steel grinding head 22. Four are shown in the figure, and in applications, there can also be five, six, eight, or even more, or less than four, but generally not less than three.
[0038] As the second improvement to the prior art, the roller main body 21 of this embodiment is composed of an aluminum core 211 and a stainless steel shell 212. The stainless steel shell 212 is wrapped outside the aluminum core 211. As can be seen from a plurality of drawings, the aluminum core 211 has a core main body 2111 and a plurality of protruding parts 2112 distributed on the outer periphery of the core main body 2111. The inner surface of the stainless steel shell 212 includes a plurality of concave cavities 2121 corresponding to the protruding parts 2112. In the preferred design shown in the figure, the positions of the protruding parts 2112 and the concave cavities 2121 exactly correspond to the positions of the mounting tables on the outer periphery of the roller main body 21 for installing the stainless steel grinding heads 22.
[0039] In addition, the aforementioned shaft hole 4 is directly formed in the center of the aluminum core 211.
[0040] In the above improvements, the easily worn parts are made in the form of stainless steel grinding heads 22 and are detachably installed on the outer periphery of the roller main body 21. When the stainless steel grinding heads 22 are damaged during use or cannot meet the crushing particle size requirements due to excessive wear, they can be directly replaced. The spare part cost is low and the operation is convenient. The advantages of the roller main body 21 being composed of an aluminum core 211 and a stainless steel shell 212 are that in addition to the low cost of the aluminum alloy material used for the aluminum core 211, more importantly, after replacing most of the materials of the roller main body 21 with lightweight aluminum alloy materials, the entire equipment will be significantly reduced in weight to meet the lightweight requirements.
[0041] In the above improvements, although aluminum alloy materials are introduced, since both the stainless steel grinding heads 22 and the stainless steel shell 212 are made of food-grade stainless steel materials, and the working surface of the crushing wall 1 is also made of food-grade stainless steel materials, when applied to food processing equipment, it can well ensure food safety during the food processing process.
[0042] In particular, in the crushing structure of this embodiment, the composite method of the aluminum core 211 and the stainless steel shell 212 is selected as inlaid casting composite. This is because the melting points of the aluminum alloy and the stainless steel material are sufficiently different. First, the stainless steel shell 212 is cast. The stainless steel shell 212 together with the core (forming the shaft hole 4) is placed in the casting mold, and it is cooled while casting. By casting the aluminum alloy, the aluminum core 211 can be manufactured on the inner side of the stainless steel shell 212. Since the aluminum core 211 is provided with protruding portions 2112 on the outer periphery of the core main body 2111, the inner surface of the stainless steel shell 212 includes a plurality of cavities 2121 corresponding to the protruding portions 2112. The two parts after inlaid casting have a large engagement surface and high bonding strength, not inferior to the integral parts of the same material.
[0043] Embodiment 2
[0044] On the basis of Embodiment 1, in this embodiment, the crushing wall 1 of the crushing structure is further improved. Based on similar considerations, the crushing wall 1 is designed into a working layer 11 and a support layer 12. Only the working layer 11 is made of safe food-grade stainless steel material as the working surface, while the support layer 12 mainly plays a role in strength support, and the material selection flexibility is higher. If inlaid casting composite or lightweight is pursued, aluminum alloy is preferably selected. If it is assembled composite (fastening, welding, etc.), aluminum alloy can be selected, or other steels different from stainless steel, such as alloy steel, can be selected.
[0045] As described above, it is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes, increases or decreases, or replacements that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
