Description

Technical Field

[0001] The invention relates to the technical field of quinoa screening, and in particular to a quinoa grading and screening device and a screening method. Background Art

[0002] Quinoa is a plant of the genus Chenopodiaceae. It has very high nutritional value and is known as "nutritional gold" and "super grain". It is rich in protein, carbohydrates, folic acid, potassium and other nutrients, and can supplement a variety of nutrients needed by the human body. In addition, quinoa is also rich in dietary fiber, which helps promote digestion and relieve constipation. The seeds of quinoa are small and shaped like small round pills.

[0003] Before quinoa is packaged and sold, it needs to go through a series of processing. During the harvesting and threshing process, plant stems and grass clippings will be mixed into the quinoa, and there will be shriveled grains in the harvested quinoa that need to be screened out.

[0004] However, the epidermis of quinoa also contains a naturally occurring substance called saponin, which is a water-soluble substance between the epidermis and the endosperm of quinoa. It has a slightly bitter taste and is slightly toxic. In order to ensure its quality, safety and compliance with relevant standards, saponin needs to be removed during the screening and cleaning of quinoa. By putting saponin in water and rubbing and washing the quinoa by hand, repeating this process about 5 times, the saponin can be effectively removed. However, when factories produce and process a large amount of quinoa, workers have been rubbing it by hand, which is time-consuming and laborious.

[0014] A quinoa grading and screening method comprises the following steps:

[0015] S1: Pour clean water into the inner side of the fixed shell and the fixed cylinder, pour the uncleaned quinoa into the fixed cylinder, start the first motor, the first motor causes the roller to rotate, drives the first motor to operate, and under the action of the first pulley, the first bevel gear is rotated through the connection of the belt, and then through the gear transmission, the cam is rotated while driving the toothed plate to move back and forth, and through meshing with the gear one, the gear one is caused to rotate back and forth, thereby causing the connecting chamber and the rotating cylinder to rotate back and forth in opposite directions respectively;

[0016] S2: When the first leak hole and the second leak hole overlap, the quinoa with the saponin removed will pass through the two and fall onto the conveyor belt. As the conveyor belt is transported, the quinoa is carried by the fan-shaped baffle and sent to the inner side of the conical cylinder. The fan-shaped baffle continues to move with the conveyor belt. When the fan-shaped baffle contacts the scraper bar, the fan-shaped baffle will be pushed into the inner side of the conveyor belt through the first connecting groove. When the fan-shaped baffle pushed into the inner side of the conveyor belt contacts the baffle bar again, it will be pushed out to the outer side of the conveyor belt.

[0017] S3: After the quinoa falls into the inner side of the conical cylinder, the third motor and the hot fan are started, the third motor rotates the gear 4, and the inner cylinder and the conical cylinder rotate simultaneously under the condition of meshing with the outer gear ring 2. When the conical cylinder rotates, the quinoa on the inner side enters the inner cylinder in cooperation with the inclined plate. When the inner cylinder rotates, the wet quinoa is driven to rotate with the inner cylinder under the connection of the push plate;

[0018] S4: After the quinoa inside the inner cylinder is dried, start the second motor, which causes gear three to rotate. When gear three rotates, the meshing inner gear ring two rotates, which causes multiple sets of gears two to rotate together, causing the opening and closing plate and the pushing plate to flip, and then the opening and closing plate is moved out from the inside of the second connecting groove. While the inner cylinder continues to rotate, the quinoa dried in the inner cylinder will fall into the outer cylinder through the second connecting groove, and finally be collected to the inside of the receiving box through the discharge port.

[0019] Compared with the prior art, the present invention provides a quinoa grading and screening device and screening method, which have the following beneficial effects:

[0020] 1. A quinoa grading and screening device and screening method, wherein the cam rotates so that the tooth plate drives the gear 1 to rotate back and forth, and the gear 1 meshes with the outer gear ring 1 and the inner gear ring 1, thereby causing the rubbing rod 1 and the shifting rod 3 to reciprocate continuously and rotate in opposite directions to each other, and at the same time cooperates with the shifting rod 1 and the rubbing rod 2 to simulate the rubbing action of human hands in water to remove the saponin on the quinoa, effectively saving manpower and improving processing efficiency, and grass clippings and shriveled grains can also be screened out in the water at the same time.

[0021] 2. A quinoa grading and screening device and screening method. When the wet quinoa enters the inner side of the inner cylinder, the third motor is started to rotate the inner cylinder. While the inner cylinder rotates, the wet quinoa is driven by the pushing plate to follow the inner cylinder to rotate to the upper side and then scatters down, so that the scattered wet quinoa can be dried more evenly by hot air, thereby accelerating the drying rate, ensuring the drying quality, and avoiding affecting the subsequent packaging and sales.

[0022] 3. A quinoa grading and screening device and screening method. When the moist quinoa is blown and dried by a hot fan on the inner side of an inner cylinder, the moist quinoa will continuously fall down from the upper side driven by a pushing plate. This can separate some saponins mixed in the moist quinoa from the quinoa under the action of the hot fan, and blow the saponins into a collecting cylinder, thereby effectively screening and ensuring the quality of the quinoa.

[0023] 4. A quinoa grading and screening device and screening method. After the quinoa is dried, the opening and closing plate and the pushing plate are flipped at the same time under the drive of the second motor. The opening and closing plate is flipped outward to one side and fits with the inner wall of the outer cylinder. As the inner cylinder continues to rotate, the dried quinoa immediately enters the outer cylinder through the second connecting groove, and is scraped by the opening and closing plate so that the dried quinoa falls into the receiving box through the discharge port, thereby efficiently completing the discharge and collection, and avoiding the dried quinoa from remaining in the outer cylinder and causing waste.

[0050] Specifically, after the quinoa falls into the inner side of the conical tube 61, the third motor 622 and the hot fan 8 are started. The third motor 622 rotates the gear four 623, and the inner tube 67 and the conical tube 61 are rotated at the same time under the condition of meshing with the outer gear ring 2 619. When the conical tube 61 rotates, the quinoa on the inside thereof enters the inner tube 67 in cooperation with the inclined plate 62.

The inner cylinder 67 drives the quinoa to rotate continuously until the wet quinoa is completely dried. However, during the drying process, the saponins mixed in the quinoa will be blown into the collecting cylinder 620.

[0055] A quinoa grading and screening method comprises the following steps:

[0056] S1: Pour clean water into the inner side of the fixed shell 3 and the fixed cylinder 41, pour the uncleaned quinoa into the fixed cylinder 41, start the first motor 54, the first motor 54 causes the roller 52 to rotate, drives the first motor 54 to operate, and under the action of the first pulley 53, the first bevel gear 57 is rotated through the connection of the belt 56, and then through the gear transmission, the cam 46 is rotated while driving the toothed plate 44 to move back and forth, and through the engagement with the gear 1 43, the gear 1 43 is caused to rotate back and forth, so that the connecting chamber 42 and the rotating cylinder 410 are respectively rotated back and forth in opposite directions;

[0057] S2: When the first leak hole 49 and the second leak hole 418 overlap, the quinoa with the saponin removed will pass through the two and fall onto the conveyor belt 51. As the conveyor belt 51 is transported, the quinoa is carried by the fan-shaped baffle 513 and sent to the inner side of the conical cylinder 61. The fan-shaped baffle 513 continues to move with the conveyor belt 51. When the fan-shaped baffle 513 contacts the scraper bar 515, the fan-shaped baffle 513 will be pushed into the inner side of the conveyor belt 51 through the first connecting groove 511. When the fan-shaped baffle 513 that has been pushed into the inner side of the conveyor belt 51 contacts the baffle bar 516 again, it will be pushed out to the outer side of the conveyor belt 51.

[0058] S3: After the quinoa falls into the inner side of the conical cylinder 61, the third motor 622 and the hot fan 8 are started, the third motor 622 rotates the gear 4 623, and the inner cylinder 67 and the conical cylinder 61 are rotated at the same time under the condition of meshing with the outer gear ring 2 619. When the conical cylinder 61 rotates, the quinoa on the inner side enters the inner cylinder 67 in cooperation with the inclined plate 62. When the inner cylinder 67 rotates, the wet quinoa is driven to rotate with the inner cylinder 67 under the connection with the push plate 610;

[0059] S4: After the quinoa inside the inner cylinder 67 is dried, start the second motor 616. The second motor 616 rotates the gear three 617. When the gear three 617 rotates, the inner gear ring 2 615 is engaged to rotate, which prompts the multiple sets of gear two 613 to rotate together, so that the opening and closing plate 69 and the pushing plate 610 are flipped, and then the opening and closing plate 69 is moved out from the inside of the second connecting groove 68. While continuing to rotate with the inner cylinder 67, the quinoa dried in the inner cylinder 67 will fall into the outer cylinder 65 through the second connecting groove 68, and finally be collected to the inside of the receiving box 2 through the discharge port 66.

[0060] When in use, the inner sides of the fixed shell 3 and the fixed cylinder 41 are filled with clean water, and then the quinoa that needs to be screened and the saponin is removed is poured into the fixed cylinder 41. The quinoa will fall to the connecting cavity 42 by gravity, and the grass clippings and shriveled grains contained therein will first float to the water surface, and then the first motor 54 is started to rotate the first pulley 53 and the roller 52 at the same time, and the first pulley 53 drives the first bevel gear 57 to rotate through the belt 56. When the first bevel gear 57 rotates, it meshes with the second bevel gear 58, and at the same time, the cam 46 is continuously rotated on the inner side of the connecting frame 45, so that the tooth plate 44 moves back and forth, and the tooth plate 44 meshes with the gear one 43. When the gear one 43 rotates back and forth, it meshes with the outer gear ring one 415 and the inner gear ring one 415 at the same time. The tooth ring 1 419 is meshed, so that the connecting chamber 42 and the rotating drum 410 rotate back and forth in opposite directions respectively, so that the rubbing rod 1 411 and the rubbing rod 2 416 move in opposite directions to each other, and the quinoa is rubbed under the cooperation of the lever 1 412 and the lever 3 417. The saponin rubbed off will float to the water surface together with grass clippings, etc. When the first leakage hole 49 and the second leakage hole 418 coincide with each other, the quinoa with the saponin removed will fall onto the conveyor belt 51 through the two. The conveyor belt 51 runs simultaneously under the rotation of the roller 52, and the wet quinoa is driven to move into the inner side of the conical cylinder 61 through the fan-shaped baffle 513. As the conveyor belt 51 runs, the wet quinoa attached to the surface of the conveyor belt 51 is scraped off by the scraper 515. The third motor 622 and the hot fan 8 are then started. The third motor 622 rotates the gear 4 623 and rotates the inner cylinder 67 and the conical cylinder 61 at the same time under the condition of meshing with the outer gear ring 2 619. When the conical cylinder 61 rotates, the quinoa on the inner side enters the inner cylinder 67 in cooperation with the inclined plate 62. When the inner cylinder 67 rotates, the wet quinoa is driven by the pushing plate 610 and follows the inner cylinder 67 to rotate to the upper side and then scatters. The inner cylinder 67 drives the quinoa to rotate continuously until the wet quinoa is completely dried. However, during the drying process, the saponins mixed in the quinoa will be blown into the collecting cylinder 620. Then, after the quinoa on the inner side of the inner cylinder 67 is dried, the third motor 622 rotates the gear 4 623 and the hot fan 8 is started. The second motor 616 rotates the gear three 617, and the gear three 617 rotates while engaging the inner gear ring 2 615 to rotate, thereby prompting the multiple sets of gear two 613 to rotate together, causing the opening and closing plate 69 and the pushing plate 610 to flip, and then the opening and closing plate 69 is moved out from the inner side of the second connecting groove 68, and one end of the opening and closing plate 69 is flipped to contact the inner wall of the outer cylinder 65 and then stops. While continuing to rotate with the inner cylinder 67, the dried quinoa in the inner cylinder 67 will fall into the outer cylinder 65 through the second connecting groove 68, and finally, under the scraping of the opening and closing plate 69 as the inner cylinder 67 rotates, the dried quinoa is collected to the inner side of the receiving box 2 through the discharge port 66, and then the staff will carry out the next step of packaging.
