[0002] Food crushing is an important link in the food processing process. Generally, a crushing device is used to crush food. It involves changing the physical properties of food, which in turn affects the quality and functionality of food. Crushing can change the particle size of food raw materials, improve the mixing uniformity in subsequent processing, accelerate the dissolution speed, improve the taste of food, and control the particle sizes of multiple similar materials. The operation of the crushing device is mostly achieved through physical means.

[0003] However, when the existing crushing device is in use, generally all the food particles piled up together are introduced into the crushing device, and the internal crushing mechanism will crush the food with different particle sizes. However, during the crushing process, the crushing methods for large particles and small particles are different, and the crushing structures are also different. Some structures have high efficiency in crushing large-particle food, while the efficiency in crushing small-particle food is poor. Some structures have high efficiency in crushing small-particle food, while the efficiency in crushing large-particle food is poor. The food particles crushed by the existing food crushing device have different sizes and are crushed together, which will lead to poor efficiency in crushing food particles.

[0004] Based on the above situation, it is necessary to design a food crushing device with a screening structure to solve the above problems. Content of the Utility Model

Detailed implementation manners

[0024] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below with reference to specific illustrations.

[0025] Refer to Figures 1 - 7As shown in the figure, a food crushing device with a screening structure includes a device frame 1, an inlet channel 2 and an outlet channel 3 fixedly connected to the device frame 1. A rotating barrel 4 is rotatably connected to the device frame 1. A toothed ring 8 is fixedly connected to one end of the rotating barrel 4. A motor three 9 is fixedly connected to the device frame 1. A gear 10 is connected to the output end of the motor three 9. The gear 10 meshes with the toothed ring 8. The motor three 9 drives the gear 10 to rotate, and then drives the toothed ring 8 meshed with the gear 10 to rotate, and then drives the rotating barrel 4 to rotate on the device frame 1. A drum screen 5 for screening mixed food particles is connected inside the rotating barrel 4. Spiral plates 6 are fixedly connected inside both the rotating barrel 4 and the drum screen 5. When the rotating barrel 4 is driven by the motor three 9 to rotate, it will also drive the drum screen 5 located inside the rotating barrel 4 to rotate. When mixed food particles of different sizes are placed inside the drum screen 5, the drum screen 5 will screen the food particles. The smaller food particles will fall into the rotating barrel 4, while the larger food particles will remain inside the drum screen 5. During the continuous rotation of the rotating barrel 4 and the drum screen 5, under the action of the spiral plate 6, the food particles will move towards the output ends of the rotating barrel 4 and the drum screen 5 until they are exported. According to the actual use situation, several drum screens 5 can be set. Correspondingly, a first crushing barrel 51 corresponding to the number of drum screens 5 needs to be set. And a single drum screen 5 corresponds to and is connected to a single first crushing barrel 51. During this process, the food particles can be subdivided at multiple levels, further improving the crushing efficiency.

[0026] Refer to Figure 7 As shown in the figure, further, a second crushing barrel 40 and a first crushing barrel 51 for crushing food particles are provided below the rotating barrel 4. The input ends of the second crushing barrel 40 and the first crushing barrel 51 are respectively connected to the output ends of the rotating barrel 4 and the drum screen 5. The drum screen 5 and the first crushing barrel 51 are connected through a first conveying pipeline 55, and both the second conveying pipeline 44 and the first conveying pipeline 55 are fixedly connected to the device frame 1. The food particles exported from the rotating barrel 4 and the drum screen 5 will be respectively introduced into the second crushing barrel 40 and the first crushing barrel 51. The rotating barrel 4 and the second crushing barrel 40 are connected through a second conveying pipeline 44. The food particles crushed and screened out inside the first crushing barrel 51 will fall into the second crushing barrel 40. Baffles 11 are provided at the output ends of the rotating barrel 4 and the drum screen 5. Outlet slots 12 are opened on the baffles 11. The input ends of the first conveying pipeline 55 and the second conveying pipeline 44 are respectively corresponding to the outlet slots 12. When the rotating barrel 4 and the drum screen 5 are rotating, the baffle 11 is located at the output ends of the two and does not rotate. The baffle 11 is rotatably connected to the rotating barrel 4 and the drum screen 5. The purpose is to prevent the food particles from being scattered to the outside when being exported from the output ends of the two, thereby causing a loss in the quantity of the food particles. The food particles will be exported from the position of the outlet slots 12.

[0027] Among them, a first crushing mechanism 41 and a second crushing mechanism 52 are respectively arranged inside the first crushing barrel 51 and the second crushing barrel 40. A first motor 42 and a second motor 53 are fixedly connected to the device frame 1. The output end of the first motor 42 is connected to the first crushing mechanism 41, and the output end of the second motor 53 is connected to the second crushing mechanism 52. The driving modes of the first crushing mechanism 41 and the second crushing mechanism 52 inside the first crushing barrel 51 and the second crushing barrel 40 are both driven by the driving modes of the first motor 42 and the second motor 53. The first motor 42 and the second motor 53 provide a power source for the operation of the first crushing mechanism 41 and the second crushing mechanism 52. Among them, the designs of the first crushing mechanism 41 and the second crushing mechanism 52 are reasonably designed according to the size of food particles, so that when processing food particles of similar size, they are in a high-efficiency crushing efficiency.

[0028] Refer to Figure 7 As shown, further, an arc-shaped screen 43 and an arc-shaped screen 54 are respectively arranged on the first crushing barrel 51 and the second crushing barrel 40. The output end of the first crushing barrel 51 is communicated with the second crushing barrel 40 through a communication pipeline 7. The input end of the communication pipeline 7 is sleeved outside the arc-shaped screen 43, and the output end of the communication pipeline 7 is communicated with the inside of the second crushing barrel 40. The output end of the first crushing barrel 51 is communicated with the second crushing barrel 40. In the processing of the above structure, larger food particles will be introduced into the first crushing barrel 51. Under the crushing of the first crushing mechanism 41, food particles of appropriate size are formed. The first crushing mechanism 41 has a high crushing efficiency for larger food particles. And these food particles will then be introduced into the second crushing barrel 40. The second crushing barrel 40 is originally used to process the food particles screened out by the drum screen 5. At this time, the sizes of the food particles from both channels are similar, and the second crushing mechanism 52 located inside the second crushing barrel 40 has a high crushing efficiency for food particles of this size. The output end of the introduction channel 2 penetrates through the rotating barrel 4 and extends into the drum screen 5. When feeding, the feeding operation is carried out through the introduction channel 2, and the introduction channel 2 is not in contact with the rotating barrel 4 and the drum screen 5. The input end of the export channel 3 is sleeved outside the arc-shaped screen 54. The food particles crushed by the second crushing barrel 40 will be transported to the subsequent processing process through the export channel 3.

[0029] There are various above-mentioned crushing mechanisms, and the crushing mechanism is a prior art structure. In the solutions of the first crushing mechanism 41 and the second crushing mechanism 52 described in the present utility model, a physical crushing method is provided. The purpose is to crush food through physical means. The existing physical crushing technologies mainly include: impact crushing, shear crushing, grinding crushing, etc. In the above-mentioned methods, the crushing effects of different methods and different structural distributions of the crushing structures on large particle food and small particle food are different respectively. According to the above description, no matter what kind of physical crushing method is used, the structure should be designed according to the size classification of food particles to improve the physical crushing efficiency of food. Therefore, the structures of the first crushing mechanism 41 and the second crushing mechanism 52 described in the present utility model will be designed and installed respectively according to the actual use situation, and the structures are different and not the same.
