Abstract
Description
Technical Field
[0001] This utility model relates to the field of grain processing equipment technology, specifically a green physical grain processing device. Background Technology
[0002] Grains refer to the general term for various plant seeds used in cooking, and can also be broadly referred to as "cereals." Grain crops are rich in nutrients, mainly protein, vitamins, dietary fiber, fat, and starch. Grains are important strategic resources affecting national security, political stability, economic development, and social harmony. my country is a major agricultural producer, and with scientific progress, we have made tremendous progress in total grain production. For surplus grain, we need to store it in granaries for unforeseen circumstances. When grain stored in granaries is needed, it requires processing.
[0003] Grain is generally stored in granaries. However, due to the large amount of grain stored in the granary, it is prone to mold growth, especially in humid environments. Moldy grain not only loses its edible value but may also produce toxins such as aflatoxin, which can harm human health. Furthermore, the quality of grain gradually declines with prolonged storage. For example, nutrients such as fat, protein, carbohydrates, and B vitamins in rice will be lost, leading to a deterioration in taste, color, and flavor. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.
[0017] Example 1
[0018] Please see Figure 1-3 This embodiment provides a green physical grain processing device, including a feeding frame 1. A screw conveyor 2 is positioned at the center of the feeding frame 1. A feeding plate 4 is positioned at the leftmost position of the screw conveyor 2. A drive motor 3 is positioned outside the feeding plate 4. A grain processing device 5 is positioned in front of the drive motor 3. The grain processing device 5 is fixedly positioned directly above the screw conveyor 2. A filter tank 6 is positioned above the grain processing device 5. A limit isolation plate 7 is positioned on the left side of the screw conveyor 2. A transition chamber 8 is positioned to the left of the limit isolation plate 7. A discharge conveyor interface 9 is positioned directly below the transition chamber 8. A sliding bracket 11 is positioned at the bottom of the discharge conveyor interface 9. A discharge conveyor belt 10 is positioned to the left of the discharge conveyor interface 9. A discharge chamber 14 is positioned at the top of the discharge conveyor belt 10. A speed adjustment knob 13 is positioned inside the discharge chamber 14.
[0019] Furthermore, the grain processing device 5 includes a fixed limiting plate 51, a gas emission nozzle 52, a control knob 53, a compressor 54, a comprehensive generator 55, and a mounting base 56. Fixed limiting plates 51 are provided on both sides of the grain processing device 5. Three gas emission nozzles 52 are arranged parallel to each other at the center of the fixed limiting plate 51. Each gas emission nozzle 52 is provided with a control knob 53. A mounting base 56 is provided above the gas emission nozzles 52. The compressor 54 and the comprehensive generator 55 are fixedly installed on the mounting base 56. The comprehensive generator 55 is connected to the compressor 54, and the ozone generator 55 is connected to the gas emission nozzles 52.
[0020] Furthermore, the integrated generator 55 includes an ozone generator, a gamma ray generator, a laser generator, and an ultraviolet generator. The ozone generator produces ozone, which is emitted through a gas emission nozzle 52 onto the auger-type feeding turntable 2. Ozone is a strong oxidant that can react with any organic molecule, eliminating microorganisms, bacteria, and mold. It effectively eliminates or degrades stored pests and fungal toxins in food, and 100% eliminates adult insects in grains. Ozone treatment also has safety advantages, leaving no toxic chemical residues, eliminating the risk of chemical mixing, and avoiding issues related to pesticide residues or container disposal. Ozone treatment can be applied to grain crops such as wheat and corn, significantly eliminating the original slight musty odor of grain piles, reducing the number of mold microorganisms and the types of stored molds, such as Aspergillus flavus, Aspergillus glaucus, Aspergillus niger, Aspergillus niger, and Penicillium, all of which show reduced detection rates. Furthermore, ozone treatment does not reduce the quality indicators of grains, such as head rice yield, hulling rate, yellow grains, viscosity, fatty acid value, and crack rate. Gamma ray generators and ultraviolet generators can disinfect pests present in grains, remove residual insect eggs, and improve the quality of grain storage.
[0021] Furthermore, the gas emission nozzle 52 is evenly provided with multiple equidistant exhaust holes, each with a diameter of 3mm. This increases the coverage area for grain cleaning and disinfection, and reduces the time required for subsequent processing.
[0022] Furthermore, a height adjustment bracket 12 is provided on the unloading conveyor belt 10. The height adjustment bracket 12 is located on the left side of the sliding bracket 11 and can be adjusted up and down. By adjusting the actual height of the height adjustment bracket 12, the operator can change the height angle of the unloading conveyor belt 10, thereby improving the adaptability of the device in different usage scenarios.
