Description

Technical Field

[0001] This invention relates to the field of onion powder production and processing technology, specifically to a dehydration device for onion powder production and processing. Background Technology

[0002] Onion powder is made from fresh onions through washing, peeling, slicing, dehydration, and grinding. It boasts advantages such as easy storage, low transportation costs, and stable year-round supply, making it widely used in sauces, meat products, compound seasonings, and pre-made foods. Dehydration is the core process in onion powder production, directly determining product quality, flavor retention, and processing energy consumption.

[0003] In existing technologies, onion scraps are dehydrated by laying them on a conveyor belt, which then feeds them into a drying chamber where hot air heats and dries them. However, this method has the following problems in practical use:

[0004] 1. Onion scraps tend to accumulate on the conveyor belt, resulting in uneven heating during the subsequent drying process and poor drying and dehydration.

[0005] 2. Relying solely on hot air to dry onion scraps has low drying efficiency and requires a large amount of hot air, resulting in higher energy consumption.

[0006] Therefore, it is necessary to invent a dehydration device for onion powder production and processing to solve the above problems. Summary of the Invention

[0013] Preferably, the inner wall of the right side of the sliding frame is provided with a groove, and the cam contacts the inner wall of the groove, so that the cam can push the sliding frame to slide back and forth.

[0020] Compared with the prior art, the present invention provides a dehydration device for onion powder production and processing, which has the following beneficial effects:

[0021] 1. The dehydration device for onion powder production and processing, through the set vibrating spreading mechanism, during use, the first motor drives the rotating shaft to drive the paddle to rotate, so that the paddle discharges the onion scraps inside the hopper in a quantitative manner. At the same time, the second motor drives it to reciprocate and vibrate, so that the discharged onion scraps can be evenly spread on the conveyor belt, avoiding the accumulation of onion scraps on the conveyor belt.

[0022] 2. The dehydration device for onion powder production and processing uses a conveying and drying mechanism to transport flat onion scraps via a conveyor belt during use. At the same time, an air intake fan and a heater work together to evenly apply hot air to the onion scraps, thereby achieving the drying and dehydration of the onion scraps.

[0023] 3. The dehydration device for onion powder production and processing, through the pre-dehydration mechanism, uses a fourth motor to drive the transmission rod to rotate during use. The transmission rod drives the spiral blades to transport the onion fragments, and works with the baffle plate to squeeze them, thereby achieving the dehydration treatment of the onion fragments. By performing pre-dehydration, the efficiency of subsequent drying and dehydration is improved. Attached Figure Description

[0046] Furthermore, multiple heaters 56, mounting bases 57, air intake fans 58, and dust filters 59 are provided, and the active roller 52 is rotatably installed inside the mounting frame 1 to improve drying efficiency.

[0047] Example 3:

[0048] Please see Figure 8Furthermore, in conjunction with Embodiments 1 and 2, the pre-dehydration mechanism 6 includes a mounting frame 61, which is fixedly mounted on the top of the drying chamber 55. A dehydration cylinder 62 is fixedly mounted inside the mounting frame 61, and a mesh cylinder 63 is fixedly mounted inside the dehydration cylinder 62. A feed hopper 64 is fixedly mounted on the top left side of the mesh cylinder 63. A fourth motor 65 is fixedly mounted on the left side of the dehydration cylinder 62. A transmission rod 66 is fixedly mounted on the output end of the fourth motor 65. A spiral blade 67 is fixedly mounted on the outside of the transmission rod 66 and is rotatably mounted inside the mesh cylinder 63. A hydraulic rod 68 is fixedly mounted on the outside right side of the dehydration cylinder 62. A baffle plate 69 is fixedly mounted on the telescopic end of the hydraulic rod 68. A connecting pipe 610 is fixedly mounted between the bottom of the dehydration cylinder 62 and the back of the mounting frame 1 to facilitate the extrusion and dehydration of onion scraps.

[0049] Furthermore, a through hole is provided at the top left side of the dewatering cylinder 62 corresponding to the position of the feed hopper 64, and the feed hopper 64 extends through the through hole to the outside of the dewatering cylinder 62, so that the feed hopper 64 can pass through the dewatering cylinder 62.

[0050] Furthermore, there are two hydraulic rods 68, and the two hydraulic rods 68 are symmetrically arranged around the center line of the right side of the dewatering cylinder 62. The baffle plate 69 and the corresponding position of the transmission rod 66 are provided with through holes, and the transmission rod 66 is movably installed inside the through holes, so that the hydraulic rods 68 can control the baffle plate 69 to open and close.

[0051] In actual operation, when this device is used, onion scraps are added into the feed hopper 64 and enter the mesh cylinder 63 through the feed hopper 64. The fourth motor 65 drives the transmission rod 66 to rotate, which in turn drives the spiral blade 67 to rotate. The spiral blade 67 carries the onion scraps to the right inside the mesh cylinder 63. The baffle plate 69 blocks the spiral blade 67, which squeezes the onion scraps, causing the water inside to pass through the mesh cylinder 63 and enter the dewatering cylinder 62. The water is then sent into the mounting frame 1 through the connecting pipe 610 on the dewatering cylinder 62 and discharged through the drain pipe 3.

[0052] After extrusion and dehydration, the hydraulic rod 68 drives the baffle plate 69 to move to the right and open. The onion scraps are then conveyed by the spiral blades 67 and fall into the hopper. The first motor 414 drives the rotating shaft 415 to rotate, which in turn drives the paddle plate 416 to rotate, causing the paddle plate 416 to discharge the onion scraps in a metered manner. At the same time, the second motor 422 drives the cam 423 to rotate, which, in conjunction with the spring 424, drives the sliding frame 412 to reciprocate outside the fixed rail 411, so that the hopper evenly spreads the onion scraps on the conveyor belt 54.

[0053] The third motor 51 drives the active roller 52 to rotate, which in turn drives the conveyor belt 54 to transport the onion scraps to the left and into the drying chamber 55. The air intake fan 58 draws outside air into the drying chamber 55 and heats the air with the internal heater 56 to generate hot air. The hot air dries the onion scraps on the conveyor belt 54, and the dried onion scraps are discharged from the left side.
