Description

Technical Field

[0001] The invention belongs to the technical field of oatmeal drying, and in particular relates to an oatmeal drying device. Background Art

[0002] Oatmeal is a cereal food made from oat grains that have been crushed or cut. It is usually in a flat or flake shape and is rich in dietary fiber, protein, vitamins and minerals. It is a nutritious, easy to digest and low-calorie healthy food, often used in breakfast, porridge or baked goods. In order to reduce the moisture content in oatmeal to a certain level, this helps prevent the oatmeal from getting moldy and deteriorating due to moisture during storage, thereby extending its shelf life. The dried oatmeal tastes better and is easier to chew and digest. This is because excess moisture is removed during the drying process, making the oatmeal more crispy and delicious. Therefore, in the oatmeal production process, the oatmeal needs to be dried. Among them, the microwave conveyor is one of the main drying equipment for oatmeal. A conveyor belt is installed on the lower side of the microwave conveyor. During the transmission of the oatmeal, the microwave machine is used to dry the oatmeal. However, with this drying equipment, the oatmeal is relatively stationary on the conveyor belt of the microwave machine, and the drying effect of some agglomerated oatmeal is not ideal. The position of the oatmeal itself does not change, which also affects the drying efficiency. Summary of the invention

[0003] The purpose of the present invention is to provide an oatmeal drying device to solve the problems existing in the background technology.

[0021] When the oatmeal needs to be dried, the oatmeal can be placed on the conveyor belt 12. Under the transportation of the conveyor belt 12, the oatmeal is moved to the lower side of one of the microwave machines 11, and the oatmeal is dried by the microwave machine 11. Then, during the continuous movement of the conveyor belt 12, the oatmeal is moved to the installation cover 13. The pressing wheel 201 slides left and right in the installation cover 13 at the same time. The pressing wheel 201 can crush the oatmeal entering the installation cover 13, thereby crushing the clumped oatmeal and improving the subsequent drying effect of the oatmeal. During the sliding process, the air supply mechanism supplies air to the sealing ring 23. When the pressing wheel 201 rotates, the air entering the sealing ring 23 can pass through the plurality of through holes 24 and enter the cavity 21, so that the air enters between the two rotating plates 3, and then enters the two distribution covers 32, thereby increasing the pressure in the distribution covers 32. When the pressing wheel 21 rotates, since the two distribution covers 32 are connected to the sliding frame 14 through the fixing rod 33, when the pressing wheel 21 rotates left and right, the positions of the two distribution covers 32 are relatively stationary. When the positions match, the pressure in the through slot 34 is increased, and the top block 35 is pushed out of the cavity 21, and the rebound mechanism begins to compress, so that the top block 35 is pushed out of the outer surface of the pressing wheel 201. Therefore, when the pressing wheel 201 rotates, the downward top block 35 can be pushed out to further squeeze the oatmeal on the lower side. This design allows the top block 35 to extend out of the lower side of the pressing wheel 201 when the pressing wheel 201 slides left and right to crush the oatmeal, so as to further improve the crushing effect of the oatmeal. When the through slot 34 is separated from the position of the distribution cover 32, the rebound mechanism in the through slot 34 is stretched. The top block 35 is driven to be retracted into the through groove 34, so that only the top block 35 located on the lower side can extend out of the outer surface of the pressing wheel 201. When the air pressure in the distribution cover 32 is too high, the position of the top block 35 matches the position of the distribution cover 32, and the amount of the top block 35 extending out of the pressing wheel 201 is insufficient to distribute the pressure in the distribution cover 32. The excess pressure overcomes the obstruction of the pressure valve 37, and the excess pressure is ejected outward through the pressure relief hole 36. The oatmeal passing through the mounting cover 13 is moved into another microwave machine 11 under the continuous movement of the conveyor belt 12, and the oatmeal is dried again.

[0022] The rebound mechanism includes limit grooves 4 arranged on both sides of the through groove 34, and slide rods 41 are arranged in the two limit grooves 4. The two slide rods 41 are provided with limit blocks 42 connected to the top block 35, and a spring 43 abutting against the limit blocks 42 is sleeved on the side of the slide rod 41 away from the cavity 21.

[0023] When the top block 35 extends outward from the pressure wheel 201, it drives the limit block 42 to slide in the limit groove 4 and drives the spring 43 to be compressed. When the top block 35 is separated from the distribution cover 32, the two limit blocks 42 are reset under the action of the extension of the spring 43, thereby driving the top block 35 to reset.

[0024] An electric telescopic rod 44 is disposed on the inner wall of the upper side of the mounting cover 13 , and a driving block 45 connected to the sliding frame 14 is mounted on the output end of the electric telescopic rod 44 .

[0025] When the electric telescopic rod 44 stretches and contracts alternately, it drives the driving block 45 to slide left and right. Such a design can drive the sliding frame 14 and the pressing wheel 201 to slide left and right.

[0026] The air supply mechanism includes two sleeves 5, the two sleeves 5 are connected to the inner wall of the mounting cover 13, and sliders 51 are slidably installed in the two sleeves 5. The two sliders 51 are provided with follower rods 52 that extend out of the sleeves 5 on the side facing the sliding frame 14. The two follower rods 52 are provided with follower blocks 53 connected to the sliding frame 14. Both ends of the two sleeves 5 are provided with air inlet pipes 54, and the air inlet pipes 54 are equipped with one-way air inlet valves 55. Both ends of the two sleeves 5 are provided with air outlet pipes 56, and the air outlet pipes 56 are equipped with air outlet one-way valves 57. The air outlet pipes 56 are connected to the inside of the sealing ring 23.

[0027] When the sliding frame 14 slides left and right in the mounting cover 13, the sliding frame 14 drives the follower block 53 to slide left and right in the mounting cover 13, and drives the follower rod 52 to slide left and right relative to the sleeve 5. The follower rod 52 drives the slider 51 to slide left and right in the sleeve 5. When the slider 51 slides to one side in the sleeve 5, the air on one side of the sleeve 5 can be squeezed, and the air can be sprayed outward through the air outlet pipe 56. The gas can be supplied to the sealing ring 23 through the air outlet pipe 56. After negative pressure is generated in the sleeve 5 on the other side, the outside air can enter the sleeve 5 through the air inlet pipe 54.

[0028] A plurality of fixed teeth 6 are provided on the lower side of the sliding frame 14. The fixed teeth 6 are designed to slide left and right with the sliding frame 14. Such a design can scrape the oatmeal on the conveyor belt 12 through the fixed teeth 6 to prevent the crushed oatmeal from being pressed against the upper surface of the conveyor belt 12, further improving the subsequent drying effect of the oatmeal.

[0029] Both sides of the mounting cover 13 are provided with slide grooves 61, and both ends of the sliding frame 14 are slidably assembled in the slide grooves 61. The design of the slide grooves 61 can improve the stability of the sliding frame 14 when sliding left and right.

[0030] The installation cover 13 is provided with an inspection door. The design of the inspection door can be used to inspect and maintain the equipment in the installation cover 13.
