Description
Technical Field
[0001] This utility model belongs to the technical field of dehydrated onion processing equipment, specifically a granulation device for dehydrating onions. Background Technology
[0002] Dehydrated onions are made from high-quality onions grown in green onion-growing bases. They are a purely natural product and are rich in various vitamins, amino acids, minerals and other nutrients. They have the effects of resisting cold, promoting appetite, lowering blood sugar, lowering blood lipids and blood pressure, and fighting cancer. They are a multifunctional health food.
[0003] In dehydrated onion processing, onions need to undergo pre-treatment such as peeling, removing the ends, and washing before being diced and dried in a drying device to obtain the finished product. Fresh onions release tear-inducing irritating gases during dicing. Existing dehydrated onion dicing devices only prevent workers from being irritated by the smell of diced onions by sealing these gases inside the device. However, as dicing continues, the concentration of these irritating gases gradually increases within the device. When the device is reopened for refilling or onion dicing is removed, the irritating gases still escape, causing eye irritation and tearing in workers, affecting their work. Therefore, a dehydrated onion dicing device needs to be designed that can promptly remove irritating gases during dicing and prevent them from escaping the device. Utility Model Content
[0004] To address the above technical problems, this utility model provides an onion dehydration granulating device that can promptly remove irritating gases during onion granulation and prevent the irritating gases from escaping outside the device. This solves the problem that existing onion granulating devices cannot remove irritating gases, causing workshop operators to experience tearing due to irritating gases, thus affecting normal work.
[0005] To solve the above technical problems, the technical solution of this utility model is as follows: an onion dehydration granulating device, including a working box, a feeding hopper fixedly connected to the top of the working box, a discharge port and a support leg fixedly connected to the bottom of the working box, and a granulating mechanism arranged inside. A star-shaped discharge valve is installed in both the feeding hopper and the discharge port. A grid plate is arranged in the working box below the granulating mechanism. One end of the grid plate is hinged to the inner wall of the working box, and the other end extends out of the side wall of the working box. An installation frame is fixedly connected to the side wall of the working box. A motor is fixedly connected in the installation frame. A cam is fixedly connected to the output end of the motor. The outer periphery of the cam abuts against the bottom of the grid plate. A one-way air valve is installed on the side wall of the discharge port. An air suction pipe is fixedly connected to the lower side of the feeding hopper. The other end of the air suction pipe is connected to an induced draft fan. A gas deodorization box is fixedly connected to the output end of the induced draft fan. The bottom of the induced draft fan and the gas deodorization box are both fixedly connected to the top of the working box.
[0006] Furthermore, the pelletizing mechanism includes a telescopic cylinder and pelletizing blades. Two pelletizing blades are arranged vertically opposite each other. The pelletizing blades are fixedly connected to the output end of the telescopic cylinder, and the bottom of the telescopic cylinder is fixedly connected to the inner wall of the mounting frame.
[0007] Furthermore, the pelletizing blade consists of an outer frame and a grid blade. The grid blade is located inside the outer frame and is fixedly connected to the outer frame. The outer frame is fixedly connected to a connecting plate via a connecting rod. The connecting plate is fixedly connected to the output end of the telescopic cylinder.
[0008] Furthermore, the upper layer of the gas deodorization box is an activated carbon layer and the lower layer is a water layer. A demister plate is fixedly connected between the water layer and the activated carbon layer. An air inlet pipe is fixedly connected to the lower side of the gas deodorization box. One end of the air inlet pipe is located inside the water layer, and the other end extends out of the gas deodorization box and is fixedly connected to the output end of the induced draft fan through a check valve. An air outlet pipe is fixedly connected to the top of the gas deodorization box.
[0009] Furthermore, an auger conveyor is fixedly connected to the lower end of the discharge port, and the auger conveyor is driven by an auger motor.
[0010] This utility model has the following advantages compared with the prior art:
[0011] 1. This utility model uses a suction pipe, an induced draft fan, and a gas deodorization box installed on one side of the feeding hopper. The induced draft fan continuously draws gas from the working box, creating a negative pressure inside the working box. The irritating gas produced by chopping onions in the working box is drawn into the gas deodorization box, where the irritating components are removed before being released. This prevents the irritating gas from accumulating inside the working box and then drifting out of the working box, thus preventing adverse effects on the operators in the workshop.
[0012] 2. This utility model uses a continuously vibrating grid plate below the pelletizing mechanism to disperse the pelletized onion pieces, preventing them from accumulating and clogging the grid plate. The auger conveyor transports the pelletized onion pieces, effectively preventing the volatilization of irritating gases during transport and further preventing the volatilized irritating gases from adversely affecting the operators in the workshop.

[0018] The present invention will be further described below with reference to the accompanying drawings.
[0019] like Figures 1 to 4 The onion dehydration and pelletizing device shown includes a working box 1. A feed hopper 2 is fixedly connected to the top of the working box 1, and a discharge port 3 and support legs are fixedly connected to the bottom of the working box 1. A pelletizing mechanism is installed inside the working box 1. Star-shaped discharge valves are installed in both the feed hopper 2 and the discharge port 3. These star-shaped discharge valves prevent pungent odors from escaping from the working box 1. A grid plate 6 is installed below the pelletizing mechanism inside the working box 1. The grid diameter of the grid plate 6 is smaller than the particle size of the uncropped onion balls, allowing it to support the onion balls and preventing them from falling below the working box 1. One end of the grid plate 6 is hinged to the inner wall of the working box 1, and the other end extends out of the side wall of the working box 1. A mounting frame 7 is fixedly connected to the side wall of the working box 1. A motor 8 is fixedly connected inside the mounting frame 7, and a cam 9 is fixedly connected to the output end of the motor 8. The outer periphery is in contact with the bottom of the grid plate 6. The rotation of the cam 9 drives one side of the grid plate 6 to move up and down continuously, shaking off the diced onions on the grid plate 6 to prevent them from accumulating and clogging. To facilitate observation of the operation of the components inside the working box 1, a transparent observation window is installed on one side wall of the working box 1. A one-way air valve 10 is installed on the side wall of the discharge port 3. The one-way air valve 10 is installed above the star-shaped discharge valve of the discharge port 3. External air can enter the working box 1 through the one-way air valve 10. A suction pipe 11 is fixedly connected to the lower side of the feed hopper 2. The suction pipe 11 is installed below the star-shaped discharge valve of the feed hopper 2. The other end of the suction pipe 11 is connected to the blower 12. The output end of the blower 12 is fixedly connected to the gas deodorization box 13. The bottom of the blower 12 and the gas deodorization box 13 are both fixedly connected to the top of the working box 1.
[0020] In order to move the dicing blade 5 to dic the onion bulb, the dicing mechanism includes a telescopic cylinder 4 and dicing blades 5. Two dicing blades 5 are arranged vertically opposite each other, and two telescopic cylinders 4 are also provided. Each dicing blade 5 is fixedly connected to the output end of the telescopic cylinder 4. The bottom of the telescopic cylinder 4 is fixedly connected to the inner wall of the mounting frame 7. In this embodiment, the telescopic cylinder 4 is preferably a hydraulic telescopic cylinder. At the same time, an operating control console adapted to the hydraulic telescopic cylinder is provided next to the device.
[0021] In order to chop the onion bulbs, the dicing knife 5 consists of an outer frame 51 and a grid blade 52. The grid blade 52 is located inside the outer frame 51 and is fixedly connected to the outer frame 51. The outer frame 51 is fixedly connected to a connecting plate 54 via a connecting rod 53. The connecting plate 54 is fixedly connected to the output end of the telescopic cylinder 4.
[0022] To remove the irritating tear gas produced by freshly chopped onions, the gas deodorizing box 13 has an activated carbon layer 15 on the upper layer and a water layer 14 on the lower layer. The water layer 14 is filled with cold water. A demisting plate 16 is fixedly connected between the water layer 14 and the activated carbon layer 15. An air inlet pipe 17 is fixedly connected to the lower side of the gas deodorizing box 13. One end of the air inlet pipe 17 is located inside the water layer 14, and the other end extends out of the gas deodorizing box 13 and is fixedly connected to the output end of the blower 12 through a check valve 21. The check valve 21 can prevent the liquid in the water layer 14 in the gas deodorizing box 13 from flowing back into the blower 12. An air outlet pipe 18 is fixedly connected to the top of the gas deodorizing box 13. The lower side of the gas deodorizing box 13 has a pipe opening for replacing the water inside and a corresponding valve.
[0023] To facilitate the transport of diced onion pieces to the drying device, a screw conveyor 19 is fixedly connected to the lower end of the discharge port 3. The input end of the screw conveyor 19 is connected to the discharge port 3, and the output end of the screw conveyor 19 extends to the drying device. The screw conveyor 19 is driven by a screw motor 20.
[0024] The specific working process of this utility model is as follows:
[0025] Open the star-shaped discharge valves on the feed hopper 2 and discharge port 3 respectively, and add the pre-treated onion balls into the feed hopper 2. The onion balls are continuously fed into the working box 1 and fall onto the grid plate 6. Start the motor 8 and the blower 12. The motor 8 rotates and drives the cam 9 to rotate, thereby driving one end of the grid plate 6 to move up and down. Control the output ends of the two telescopic cylinders 4 to extend and then retract, reciprocating to continuously chop the onion balls. The extension of the output ends of the two telescopic cylinders 4 drives the two dicing blades 5 to move towards each other, continuously squeezing the onion balls between the two dicing blades 5. The onion balls that come into contact with the grid blades 52 of the dicing blades 5 are continuously cut into onion balls under pressure and fall from the gaps between the grid blades 52 onto the grid plate 6, and are diced. The onion balls are continuously shaken off the up-and-down vibrating grid plate 6. The gas falls below the working box 1 and enters the screw conveyor 20 through the discharge port 3, where it is continuously transported out. During this period, the blower 12 continuously draws in the gas inside the working box 1, creating a negative pressure in the working box 1 to prevent the irritating gas produced by the diced onions from escaping outside the working box 1. Outside air enters the working box 1 through the one-way valve 10, continuously counteracting the negative pressure inside the working box 1. The irritating gas is continuously drawn into the gas deodorization box 13 by the blower 12 and enters the water layer 14 through the air inlet pipe 17. First, it passes through the cold water in the water layer 14, which dissolves and absorbs some of the irritating components in the water-soluble gas. The remaining components follow the airflow through the demister plate 16 to separate the water mist and then enter the activated carbon layer 15, where they are adsorbed and removed by the activated carbon. Finally, the deodorized gas is discharged from the air outlet pipe 18.
