Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0047] Reference Figures 1 to 12 This utility model provides an embodiment of a food-grade pulverizing and drying integrated machine, comprising a shell 1, a protective and supporting body. An inner plate 2, supporting and positioning components, is fixedly connected inside the shell 1.

The inner wall of drive wheel 9 is fixedly connected to the other end of drive shaft 8. The outer side of driven shaft 10 is rotatably connected to the inside of housing 1. The inner wall of driven wheel 11 is fixedly connected to the outside of driven shaft 10. The outer drive of belt 36 is connected to the outside of driven wheel 11 and the outside of drive wheel 9. The other end of driven shaft 10 away from driven wheel 11 is fixedly connected to rotating shaft 12.
[0048] A fixed shaft 13 is fixedly connected to the outside of the rotating shaft 12, fixing the position of the crushing roller 14. Two sets of crushing rollers 14 are fixedly connected to the outside of the fixed shaft 13 to crush material particles. Multiple elastic components providing scraping ability are provided outside the fixed shaft 13. Each elastic component includes a hollow rod 15, a sliding rod 16, a spring 17, and a scraper 18. The hollow rod 15 is fixedly connected to the outside of the fixed shaft 13, the sliding rod 16 is slidably connected to the inside of the hollow rod 15, one end of the spring 17 is fixedly connected to the outside of the sliding rod 16, and the other end of the spring 17 is fixedly connected to the inside of the hollow rod 15. The scraper 18 is fixedly connected to the outside of the sliding rod 16 and slidably connected to the outside of the filter plate 4. A dust collection pipe 19 is fixedly connected to the inner wall of the outer shell 1 to collect dust and impurities. A cloth bag 20 is fitted outside the dust collection pipe 19 to filter dust particles. The outer casing 1 is provided with a hinge 21, and a movable plate 22 is fixedly connected to the outside of the hinge 21 for easy inspection of material entry and exit. The dust collection pipe 19 is provided with a one-way valve inside. A handle 23 is fixedly connected to the front of the movable plate 22. A material transfer groove 24 is opened on the inner wall of the movable plate 22. A material transfer pipe 25 is fixedly connected to the front of the movable plate 22. The material transfer pipe 25 is positioned corresponding to the material transfer groove 24. A material transfer box 26 is fixedly connected to the outside of the material transfer pipe 25.
[0049] Two base plates 27 are fixedly connected to the bottom of the support frame 6 to stabilize the equipment. A fan box 28 is fixedly connected to the rear exterior of the outer casing 1, and a dustproof plate 29 is fixedly connected to the inner wall of the outer casing 1 to prevent dust from spreading. Two placement slots 30 are opened inside the outer casing 1, and heating wires 31 are fixedly connected inside the two placement slots 30 to dry the material. A second dustproof plate 32 is fixedly connected inside the outer casing 1, and a discharge chute 33 is opened on the inner wall of the outer casing 1 to guide the material out. A discharge pipe 34 is fixedly connected to the bottom of the outer casing 1, and the position of the discharge pipe 34 corresponds to that of the discharge chute 33. A sealing cover 35 is fixedly connected to the outside of the discharge pipe 34 to control the discharge switch.
[0050] Working principle: The operator transfers the food to be processed through the transfer box 26 and transfer pipe 25 into the interior of the filter plate 4, then puts the cloth bag 20 into the dust transfer pipe 19, connects the power supply, and turns on the heating wire 31 and the fan inside the fan box 28. The heating wire 31 heats the surrounding air, and the fan transmits airflow, which transfers the hot air to the interior of the outer shell 1.
[0051] The motor 7 is started, and its output drives the drive shaft 8 to rotate. The drive shaft 8 drives the drive wheel 9 to rotate. Since the belt 36 is wrapped around the driven wheel 11 and the drive wheel 9, the drive wheel 9 drives the driven wheel 11 to rotate synchronously while rotating. The shape of the drive wheel 9 is larger than that of the driven wheel 11, so the number of rotations of the drive wheel 9 is less than that of the driven wheel 11, thus reducing the burden on the motor 7. The driven wheel 11 drives the driven shaft 10 to rotate, which in turn drives the belt 36 to rotate. The belt 36 drives the fixed shaft 13 to rotate, which in turn drives multiple crushing rollers 14 to rotate. The rotation of the crushing rollers 14 crushes the food that is fed in, while hot air dries the food. The one-way valve is opened, so that when the dust generated during subsequent processing is blown up by the hot air, since the interior of the outer casing 1 only has one upward outlet, the dust is carried by the airflow to accumulate inside the dust transfer pipe 19 and then transferred to the cloth bag 20.
[0052] During the food crushing process, the fixed shaft 13 also drives the hollow rod 15 to rotate. With the elastic potential energy provided by the spring 17, the scraper 18 is pressed tightly against the outer surface of the filter plate 4. After the food is crushed, it falls into the small holes in the filter plate 4, but it is not immediately transferred to the space between the inner plate 2 and the outer shell 1. Therefore, under the scraping force of the scraper 18, the crushed food is transferred in a circular rotation through the small holes of the filter plate 4 to the space between the inner plate 2 and the outer shell 1. At the same time, the scraper 18 can also stir the uncrushed food, and the uncrushed food continues to be crushed.
[0053] Open the sealing cover 35 and transfer the crushed food inside the outer shell 1 to the outside of the device through the discharge chute 33. When it is necessary to adjust the size of the filter holes of the filter plate 4, the filter plate 4 can be disassembled by turning the bolt 5 and the filter plate 4 with the required filter hole size can be installed in its original position.
[0054] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
