Abstract
Description
Technical Field
[0001] The invention relates to the technical field of feed processing, and in particular to a raw material preprocessing device and a processing method for compound feed processing. Background Art
[0002] In the process of compound feed processing, the pretreatment of raw materials is crucial, which is directly related to the quality of feed and the health of animals. As the basic material for animal breeding, feed has many types, mainly including grains, proteins, minerals, vitamins and additives, etc. Among them, grain raw materials such as corn, barley, wheat, etc., have become the main ingredients in compound feed due to their rich energy and easy digestion and absorption. However, these grain raw materials are very susceptible to contamination by various microorganisms during planting, harvesting, storage and transportation, especially the invasion of Aspergillus flavus; Aspergillus flavus is a fungus widely found in nature. It can produce aflatoxin, a strong carcinogen. When cereal feed raw materials are infected with Aspergillus flavus, not only will the nutritional value of the feed be reduced, but toxic substances will also remain in the feed. These toxins are difficult to be decomposed in the animal body. Long-term accumulation will pose a great threat to the health of the animal. Specifically, after eating feed infected with aflatoxin, animals may experience symptoms such as slow growth and development, decreased production performance, weakened disease resistance, and impaired reproductive performance. What is more serious is that aflatoxin has a strong toxic effect on the liver of animals, which can cause liver enlargement, liver cell necrosis, and even liver cancer. Traditional feed raw material pretreatment methods, such as impurity removal, crushing, mixing, and granulation, mainly focus on improving the palatability, nutritional balance, and processing efficiency of feed, but lack effective detection and removal mechanisms for potential contaminants in raw materials. Therefore, in the traditional pretreatment process, corn and other cereal raw materials infected with aflatoxin are often difficult to be discovered and removed in a timely manner, thereby increasing the risk of aflatoxin content in finished feed products, which not only affects the quality and safety of feed products, but also restricts the sustainable development of the animal husbandry industry; At the same time, existing pretreatment devices generally do not include raw material cleaning in the standard process. Taking common grain raw materials such as corn and wheat as examples, these raw materials are very easy to absorb dust, soil particles and other impurities in the air during natural growth, harvesting and storage. Raw materials that have not been effectively cleaned are directly involved in feed processing, which will cause a certain amount of dust and impurities to be mixed into the finished feed. This not only reduces the purity and nutritional value of the feed, but may also cause a series of adverse consequences such as digestive discomfort, decreased immunity and even disease transmission after animals eat it, seriously damaging the healthy and sustainable development of the breeding industry. In addition, long-term intake of dusty feed will also affect the growth performance of animals, reduce feed conversion rate, increase breeding costs, and pose a threat to the economic interests of farmers.

[0024] The working principle includes the following steps: Step 1: add a proper amount of water into the inner cavity of the water tank 61 and the return water tank 62, so that the water level in the inner cavity of the water tank 61 is located at the overflow hole 63, start the first conveyor belt 8, the second conveyor belt 12, the third conveyor belt 65 and the fourth conveyor belt 66 for conveying the grain feed raw materials, start the fan 9, the water pump 68, the hot air blower 73 and the motor 712, pour the grain feed raw materials into the left side of the top of the first conveyor belt 8, and use the first conveyor belt 8 to drive the grain feed raw materials to move to the right until the grain feed raw materials move to the right end of the first conveyor belt 8. The grain feed raw materials will fall from the first conveyor belt 8 under the factor of gravity. As the fan 9 is started, the wind pressure generated by the fan 9 is blown out through the air duct 10 and blown to the grain feed raw materials in a free-falling state. Under the action of the wind pressure, the shriveled raw materials, dust and light impurities mixed in the grain feed raw materials are blown upward (such as corn cobs, corn silks and rice husks, etc.) and fall on the second conveyor belt 12. The second conveyor belt 12 is used to convey these impurities to the right until they are moved out of the inner cavity of the main box 1 through the first discharge chute 3 and fall for unified collection and processing. The gravity of the intact grain feed raw materials is greater than the wind pressure generated by the fan 9, and they will continue to fall downward into the inner cavity of the water tank 61. Step 2, start the water pump 68. With the cooperation of the water pump 68, the water inlet pipe 69 and the water outlet pipe 610, the water in the inner cavity of the return tank 62 will be pumped out and sprayed into the inner cavity of the water tank 61 through the first nozzle 67. When the cereal feed raw materials that fall into the inner cavity of the water tank 61 pass through the first nozzle 67, the first nozzle 67 will be used to wash away the dust attached to the cereal feed raw materials, and the cereal feed raw materials that fall into the inner cavity of the water tank 61 will be immersed in the water of the water tank 61. Since the density of the intact cereal feed raw materials that are not infected with aflatoxin is greater than that of water, they will sink to the bottom of the water, while the cereal feed raw materials infected with aflatoxin are often loose in texture and reduced in density due to mildew, and will float on the water surface or be suspended in the water. Under the power of the water sprayed by the first nozzle 67, the water in the inner cavity of the water tank 61 will move to the left, thereby causing the cereal feed raw materials floating on the water surface and those in a suspended state to disperse. The grain feed materials infected with aflatoxin scattered in the water follow the water flow to move to the left until they move to the fourth conveyor belt 66. The fourth conveyor belt 66 will drive the grain feed materials infected with aflatoxin to move to the left until they move to the left end of the fourth conveyor belt 66, and then they will fall on the first unloading plate 64, and fall out of the inner cavity of the main box 1 through the second discharging trough 4 along with the first unloading plate 64. At the same time, as the liquid level in the inner cavity of the water tank 61 rises, the water in the water tank 61 will flow out of the inner cavity of the water tank 61 through the overflow hole 63, and flow into the inner cavity of the return trough 62. The intact grain feed materials sunk to the bottom of the water tank 61 will fall on the top of the third conveyor belt 65. Then, the third conveyor belt 65 will drive the intact grain feed materials sunk to the bottom of the water tank 61 to move to the right until they move to the right end of the third conveyor belt 65, which will cause the intact grain feed materials to fall on the top of the shaking plate 78.

8. A method for preprocessing raw materials for compound feed processing, which is applied to a raw material preprocessing device for compound feed processing as claimed in claim 7, and specifically comprises the following steps: Step 1: Add an appropriate amount of water into the inner cavity of the water tank (61) and the return water tank (62) to make the water level in the inner cavity of the water tank (61) be located at the overflow hole (63), start the first conveyor belt (8), the second conveyor belt (12), the third conveyor belt (65) and the fourth conveyor belt (66) for conveying the grain feed raw materials, start the fan (9), the water pump (68), the hot air blower (73) and the motor (712), pour the grain feed raw materials into the left side of the top of the first conveyor belt (8), use the first conveyor belt (8) to drive the grain feed raw materials to move to the right, until the grain feed raw materials move to the right end of the first conveyor belt (8), and the grain feed raw materials will be moved from the left side of the top of the first conveyor belt (8) under the factor of gravity. The first conveyor belt (8) falls off, and at the same time, due to the start-up of the fan (9), the wind pressure generated by the fan (9) is blown out through the air duct (10) and blown towards the grain feed raw materials in a free-falling state. Under the action of the wind pressure, the shrunken raw materials, dust and light impurities mixed in the grain feed raw materials are blown upward and fall onto the second conveyor belt (12). The second conveyor belt (12) is used to transport these impurities to the right until they are moved out of the inner cavity of the main box (1) through the first discharge chute (3) and fall for unified collection and treatment. The gravity of the intact grain feed raw materials is greater than the wind pressure generated by the fan (9), and they continue to fall downward into the inner cavity of the water tank (61); Step 2: Start the water pump (68). The water pump (68), the water inlet pipe (69) and the water outlet pipe (610) cooperate to pump water out of the inner cavity of the return water tank (62) and spray it into the inner cavity of the water tank (61) through the first nozzle (67). When the grain feed raw materials that fall into the inner cavity of the water tank (61) pass through the first nozzle (67), the first nozzle (67) will be used to wash away the dust attached to the grain feed raw materials, and the grains that fall into the inner cavity of the water tank (61) will be washed away. The feed raw materials will be immersed in the water of the water tank (61). Since the density of intact grain feed raw materials not infected by aflatoxin is greater than that of water, they will sink to the bottom of the water. However, the grain feed raw materials infected by aflatoxin are often loose in texture and have a reduced density due to mold, and will float on the water surface or be suspended in the water. Under the power of the water sprayed by the first nozzle (67), the water in the inner cavity of the water tank (61) will move to the left, thereby causing the grain feed raw materials floating on the water surface and being suspended in the water to move to the left. The aflatoxin-infected cereal feed raw materials follow the water flow to move to the left until they move to the fourth conveyor belt (66). The fourth conveyor belt (66) drives the aflatoxin-infected cereal feed raw materials to move to the left until they move to the left end of the fourth conveyor belt (66), and then fall onto the first discharge plate (64). Along with the first discharge plate (64), they fall out of the inner cavity of the main box (1) through the second discharge chute (4). At the same time, as the liquid level in the inner cavity of the water tank (61) rises, the water tank (6 1) The water in the water tank (61) will flow out of the inner cavity of the water tank (61) through the overflow hole (63) and flow into the inner cavity of the return water tank (62). The intact grain feed raw materials that have sunk to the bottom of the water tank (61) will fall on the top of the third conveyor belt (65). The third conveyor belt (65) will then drive the intact grain feed raw materials that have sunk to the bottom of the water tank (61) to move to the right until they move to the right end of the third conveyor belt (65), causing the intact grain feed raw materials to fall on the top of the shaking plate (78); Step 3, start the hot air blower (73), the hot air generated by the hot air blower (73) is ejected through the second nozzle (74), and then the intact grain feed raw materials on the top of the shaking plate (78) are dried, and the motor (712) is started, and the output end of the motor (712) drives the toothless gear (714) to rotate clockwise through the connecting rod (713), and the clockwise rotation of the toothless gear (714) can cause the knocking rod (710) to move downward and squeeze the second spring (711) to elastically deform until the toothless gear (714) and the knocking rod (710) are separated, and then the knocking rod (710) is pushed to move upward under the elastic force of the second spring (711) until the knocking rod (710) returns to the initial position, and the knocking rod (710) can be used to knock the shaking plate (78), and then under the action of the shaking plate (78), The telescopic rod (76) is driven to move up and down in the inner cavity of the telescopic cylinder (75), and the first spring (77) is stretched to undergo elastic deformation, thereby causing the shaking plate (78) to shake up and down. Repeating the above actions can cause the shaking plate (78) to shake continuously. The shaking of the shaking plate (78) not only causes the feed raw materials above the shaking plate (78) to move to the right, but also causes the feed raw materials above the shaking plate (78) to scatter, thereby preventing the feed raw materials from adhering together, thereby increasing the drying effect, until the feed raw materials above the shaking plate (78) move to the right side of the shaking plate (78), thereby causing the feed raw materials above the shaking plate (78) to fall to the top of the second unloading plate (715), and fall out of the inner cavity of the main box (1) along with the second unloading plate (715) through the third discharging chute (5), thereby completing the screening and cleaning of the cereal feed raw materials.
