Description

Technical Field

[0001] This utility model belongs to the field of dehydrator technology, specifically, it relates to a corn germ dehydrator. Background Technology

[0002] In existing technologies, corn germ is typically stored by dehydration. While corn germ is rich in protein and fat, making it highly nutritious, it is also susceptible to microbial damage. In humid environments, mold and bacteria easily proliferate, leading to spoilage. Dehydration storage significantly reduces the moisture content of the germ, creating an environment unfavorable to microbial growth and effectively preventing mold and rancidity. Dehydration also helps maintain the quality and nutritional value of the corn germ. Moisture is a medium for microbial activity and chemical reactions; excessive moisture content accelerates the loss of nutrients and quality decline in the germ. Dehydration slows these processes, allowing the germ to maintain better quality and nutritional value during storage. Dehydrated corn germ is smaller and denser, making it easier to store and transport. Simultaneously, dehydration reduces respiration and moisture evaporation during storage, maintaining its stability. Dehydrated corn germ is also easier to process through subsequent steps such as crushing and pressing. From an economic perspective, dehydration storage reduces storage costs and increases product value.

[0003] Corn germ is typically dehydrated using a dehydrator, which removes excess water through mechanical extrusion. Since corn germ is a large-particle, fiber-rich material, a screw extruder is used for dehydration. The working principle of a screw extruder is as follows: material is fed into the machine via a screw conveyor. As the screw rotates, it moves forward. In the compression section, the pitch and inner diameter of the screw blades gradually decrease, creating progressively increasing pressure. This pressure forces the material to shrink in volume, thus squeezing out the water. Excess water is discharged through the screen openings. However, in daily use, the screen of the screw extruder is easily clogged by germ fibers, making water drainage difficult and affecting the squeezing effect. Furthermore, because corn germ is rich in fiber, the material tends to clump together during the squeezing process due to friction, which also hinders water drainage.

[0004] To address the clumping phenomenon of corn germ materials, multiple bolts are typically installed on the inner wall of the cylinder to break up the material during its movement. However, the increased number of bolts causes the material to exert force on the auger, affecting its conveying efficiency. Furthermore, the complex processing technology increases costs. Therefore, solving the clumping problem by designing a reasonable filtration device and an appropriate compression ratio is an urgent technical issue that needs to be addressed.

[0005] Chinese patent application number CN2022112676363 discloses a high-efficiency extruder, including a bottom beam. The extruder features an extrusion cylinder mounted above the bottom beam, a transmission support filter tube coaxially arranged inside the extrusion cylinder, an inner filter assembly mounted on the outer surface of the transmission support filter tube, an inner filter cavity coaxially formed in the middle of the transmission support filter tube, and an inner filter conveying assembly rotatably mounted in the middle of the inner filter cavity. This invention has a simple overall structure, is easy to use, and can fully extrude materials, removing moisture and increasing the amount of water extruded, thus improving the overall performance.

[0006] However, when this type of dehydrator is used to dehydrate corn germ, the internal filter component of the dehydration cylinder, which is responsible for filtering water, is prone to clogging, affecting water discharge and resulting in poor performance. Utility Model Content

[0036] like Figure 1-8 As shown: A corn germ dehydrator includes a base 1. A drive assembly 2 is fixedly installed at one end of the base 1. A drive shaft 3 is fixedly connected to the power output end of the drive assembly 2. An internal filter conveying assembly 10 is fixedly installed at the other end of the drive shaft 3. A discharge box 5, a water filter box 6, and a feed box 8 are sequentially fixedly installed on the base 1 at positions corresponding to the other end of the drive shaft 3. The discharge box 5, the water filter box 6, and the feed box 8 are interconnected. A drive output shaft 11 is fixedly installed at the other end of the internal filter conveying assembly 10. The drive shaft 3, the internal filter conveying assembly 10, and the drive output shaft 11 are rotatably installed in the discharge box 5, the water filter box 6, and the feed box 8. A squeezing cylinder 7 is fixedly installed in the water filter box 6. The internal filter conveying assembly 10 is rotatably connected to the squeezing cylinder 7, and the outer surface of the internal filter conveying assembly 10 is in contact with the inner wall of the squeezing cylinder 7.

[0037] The squeezing cylinder 7 includes multiple sets of first cage assemblies fixedly connected end to end. The inner surface of the first cage assembly is a conical surface. The small diameter end of the first cage assembly near the drive shaft 3 is fixedly installed at one end of the filter tank 6 near the drive shaft 3. At least one set of second cage assemblies is fixedly installed at the large diameter end of the first cage assembly near the drive output shaft 11. The inner surface of the second cage assembly is also a conical surface.

[0038] The first cage assembly includes two symmetrically arranged and fixedly connected first cage units 72. The inner surfaces of the two first cage units 72 are conical. The surface of the first cage unit 72 is provided with a plurality of uniformly arranged first filter holes. The inner surface of the first cage unit 72 is provided with a plurality of uniformly arranged water filtration grooves 74. A first external filter plate 73 is fixedly installed on the inner surface of the first cage unit 72.

[0039] The second cage assembly includes two symmetrically arranged and fixedly connected second cage units 75. The inner surfaces of the two second cage units 75 are conical surfaces, and the surfaces of the second cage units 75 are provided with a plurality of evenly arranged second filter holes. A filter screen unit 77 is fixedly installed on the inner surface of the second cage unit 75, and a second outer filter plate 76 is fixedly installed on the inner surface of the filter screen unit 77.

[0040] The corn germ material moves from the large-diameter end to the small-diameter end of the squeezing cylinder 7 under the rotation of the inner filter conveying assembly 10. During this process, the inner wall of the second cage assembly, the inner wall of the first cage assembly, and the outer surface of the inner filter conveying assembly 10 squeeze the corn germ material. The squeezed water is then filtered out from the outer walls of the second cage assembly and the first cage assembly in sequence, thus completing the squeezing process.

[0041] In this embodiment, the drive component 2 uses a motor to drive the reducer through pulleys and belts. The power output end of the reducer is fixedly connected to the drive shaft 3 through a coupling for driving. The specific drive connection principle is well known in the prior art and can be obtained commercially, so it will not be described in detail here.

[0042] A first bearing sealing box 4 is fitted on the drive shaft 3 near the discharge box 5, and the first bearing sealing box 4 is also fixedly installed on the outer wall of the discharge box 5.

[0043] The first bearing sealing box 4 is used to support the rotation of the drive shaft 3 and to seal the connection between the drive shaft 3 and the discharge box 5.

[0044] The first bearing sealing box 4 is existing technology and can be obtained commercially, so it will not be described in detail here.

[0045] The discharge box 5 includes a discharge box body 51 fixedly installed on the base 1. The upper end of the discharge box body 51 is hinged with a top cover 52, and the lower end of the discharge box body 51 is provided with a discharge port 53.

[0046] The squeezed corn germ material enters the discharge box 51 and is then discharged from the discharge port 53 for storage.

[0047] When a blockage occurs in the discharge box 51, the top cover 52 can be opened for handling, which is convenient.

[0048] The end of the water filter box 6 near the discharge box 5 is fixedly connected to the discharge box 5 by bolts and flanges.

[0049] The water filter box 6 includes a water filter box body 61 that is fixedly connected to the discharge box 5, and the water filter box body 61 is also fixedly installed on the base 1.

[0050] The lower end of the water filter box 61 is provided with a second water sludge receiving tray 62. The water filtered out by the squeezing cylinder 7 falls onto the second water sludge receiving tray 62, which transfers the discharged water.

[0051] The small-diameter end of the squeezing cylinder 7 is fixedly installed on the inner wall of the filter box 61 near the discharge box 5 by a flange and bolts, and the large-diameter end of the squeezing cylinder 7 is fixedly installed on the inner wall of the filter box 61 near the feed box 8 by a flange and bolts.

[0052] like Figure 2-6 As shown, the inner wall of the small-diameter end of the extrusion cylinder 7 and the outer surface of the inner filter conveying assembly 10 are set as discharge ports 71, and the dehydrated corn germ material is discharged from the discharge port 71 into the discharge box 5.

[0053] The inner wall of the large-diameter end of the extrusion cylinder 7 and the outer surface of the inner filter conveying assembly 10 are configured as an extrusion feed inlet 79, through which the corn germ material to be dehydrated enters the extrusion cylinder 7.

[0054] The surface of the first external filter plate 73 has a plurality of evenly distributed fourth filter holes.

[0055] The surface of the second outer filter plate 76 is provided with a plurality of evenly distributed third filter holes.

[0056] The filter unit 77 is made of multiple support bars welded in an alternating manner, which forms a water filtration channel between each pair of support bars.

[0057] When the corn germ material to be dehydrated enters the second cage assembly from the feed box 8 through the extrusion feed port 79, the inner wall of the second cage assembly has a larger filtration area than the first cage assembly. The corn germ material here has more moisture. After passing through the third filter hole of the second outer filter plate 76, the water filtration channel, and the second filter hole, it is discharged into the water filtration box 61. The water filtration channel can ensure that the water is filtered out quickly and improve the water filtration efficiency.

[0058] When the corn germ material to be dehydrated enters the first cage assembly, as the inner diameter of the first cage assembly decreases, the squeezing pressure of the inner wall of the first cage assembly on the material increases, further improving the water filtration effect. At this time, the squeezed water passes through the fourth filter hole, the water filtration tank 74, and then through the first filter hole to be filtered out into the water filtration tank 6.

[0059] The function of the water filter tank 74 is to accelerate the flow rate of water, increase the speed of water discharge, and at the same time avoid clogging, which would affect the water filtration.

[0060] like Figure 1 As shown, the feed box 8 includes a feed box body 81 fixedly connected to the end face of the filter box body 61 away from the drive assembly 2.

[0061] The feed box 81 is simultaneously connected to the water filter box 61 and is fixedly installed on the base 1.

[0062] The upper end face of the feeding box 81 is provided with a feeding port 82, and the corn germ material to be dehydrated enters from the feeding port 82.

[0063] A first water slag receiving tray 83 is provided at the lower end of the feeding box 81.

[0064] Inside the feed box 81, below the internal filter conveying assembly 10, there is a primary filter plate 84. The primary filter plate 84 can filter moisture and residue from the material. The moisture and residue from the material entering the feed box 81 after being filtered by the primary filter plate 84 fall onto the first water and residue receiving tray 83, which transfers the discharged moisture and residue.

[0065] In this embodiment, the primary filter plate 84 uses a method of opening round holes for filtration. Its specific structure and filtration principle are well known and will not be described in detail here.

[0066] like Figure 7-8 As shown, the internal filter conveying assembly 10 includes a transmission support pipe 100 fixedly connected to the other end of the transmission shaft 3.

[0067] The other end of the transmission support tube 100 is fixedly connected to a primary filter tube 102, and the other end of the primary filter tube 102 is fixedly connected to the transmission output shaft 11.

[0068] The same spiral blade 101 is fixedly installed on the outer surface of the transmission support tube 100 and the primary filter tube 102. The spiral blade 101 is arranged in a spiral shape along the outer surface of the transmission support tube 100 and the primary filter tube 102.

[0069] The diameter of the spiral blade 101 matches the diameter of the inner wall of the extrusion cylinder 7, that is, it changes with the diameter of the inner wall of the extrusion cylinder 7.

[0070] The pitch of the spiral blade 101 is set to a variable pitch, and the variable pitch of the spiral blade 101 decreases from the large diameter end to the small diameter end of the extrusion cylinder 7.

[0071] This design optimizes the compression ratio of the dewatering machine. When the material enters the squeezing cylinder 7, the rotation of the spiral blades 101 drives the material to move towards the smaller diameter end of the squeezing cylinder 7. Simultaneously, due to the decreasing diameter and pitch of the spiral blades 101, the dewatering force of the material gradually increases under the squeezing action against the inner wall of the squeezing cylinder 7. Consequently, the material will not clump during the initial dewatering stage. Furthermore, as the pitch of the spiral blades 101 decreases, the material is squeezed and dewatered to the maximum intensity when it reaches the smaller diameter end of the squeezing cylinder 7, thus improving the dewatering rate without clumping the material.

[0072] The squeezed-out water is filtered through the inner wall of the squeezing cylinder 7 and then transferred into the second water sludge receiving tray 62 below the water filter tank 61.

[0073] The primary filter tube 102 includes a tube body 1020 fixedly connected to the other end of the transmission support tube 100. The outer surface of the tube body 1020 near the transmission support tube 100 has a plurality of evenly distributed filter holes 106.

[0074] A baffle plate 103 is sealed at the connection between the pipe body 1020 and the transmission support pipe 100. The function of the baffle plate 103 is to prevent material residue from entering the interior of the transmission support pipe 100.

[0075] The tube body 1020 has multiple spaced slag discharge holes 109 at one end near the transmission output shaft 11.

[0076] A slag discharge spiral 108 is fixedly installed inside the pipe body 1020, and the slag discharge spiral 108 is arranged in a spiral shape on the inner wall of the pipe body 1020.

[0077] The rotation direction of the slag discharge screw 108 is opposite to that of the screw blade 101. With this design, when the transmission support pipe 100 and the primary filter pipe 102 rotate, the material is conveyed to the small diameter end of the extrusion cylinder 7 under the conveying action of the screw blade 101, while the filter residue in the primary filter pipe 102 is conveyed to the slag discharge hole 109 under the action of the slag discharge screw 108.

[0078] The tube body 1020 is internally configured as an inner filter chamber 107.

[0079] A screen bar filter 105 is fixedly installed on the outer surface of the tube body 1020 corresponding to the spiral blade 101. In this embodiment, the screen bar filter 105 is made of multiple stainless steel metal strips welded together to increase the water filtration rate.

[0080] A primary filter plate 104 is fixedly installed on the outer surface of the sieve bar filter 105, and the primary filter plate 104 has a plurality of evenly distributed fifth filter holes.

[0081] With this design, when the material enters the feed box 81 from the feed inlet 82, the water-slag mixture enters the inner filter chamber 107 under the action of the fifth filter hole, the screen bar filter 105 and the filter hole 106, realizing the initial filtration of the material and further improving the subsequent dewatering effect.

[0082] The water-sludge mixture in the inner filter chamber 107 is partially collected in the first water-sludge receiving plate 83, and partially discharged through the sludge outlet 109 before being collected in the first water-sludge receiving plate 83. This avoids the accumulation of sludge and liquid in the inner filter chamber 107, which would make cleaning inconvenient.

[0083] The transmission output shaft 11 passes through the inner wall of the feed box 81 and is rotatably connected to the second bearing sealing box 9. The second bearing sealing box 9 is also fixedly installed on the outer wall of the feed box 81.

[0084] The second bearing sealing box 9 is used to support the rotation of the transmission output shaft 11 and to seal the connection between the transmission output shaft 11 and the feed box 81.

[0085] The second bearing sealing box 9 is existing technology and can be obtained commercially, so it will not be described in detail here.

[0086] When using this corn germ dehydrator, the corn germ material to be dehydrated is first fed into the feed box 81 through the feed inlet 82. Under the action of the primary filter plate 104 and the screen bar filter 105, some water is filtered out and falls into the first water residue receiving tray 83. Then, the drive assembly 2 is started. The power output end of the drive assembly 2 drives the transmission shaft 3 to rotate, which in turn drives the internal filter conveying assembly 10 and the transmission output shaft 11 to rotate. Under the rotation of the spiral blades 101, the material is extruded from the feed box. The material enters the squeezing cylinder 7 through the inlet 79 for further squeezing and dehydration. The water filtered out here enters the second water slag receiving plate 62 at the lower end of the water filter box 6 to be received. As the spiral blade 101 rotates, the material is gradually squeezed dry. Finally, the squeezed material is discharged from the discharge port 71 into the discharge box 5 and finally output through the discharge port 53. During this process, the water slag mixture remaining in the inner filter cavity 107 is discharged through the slag discharge hole 109 under the action of the rotating slag discharge spiral 108 and falls into the first water slag receiving plate 83 to be received.

[0087] After the dewatering machine is used, a high-pressure water gun is used to rinse the inside of the feed box 81. At the same time, the drive component 2 is started, and the cleaning water flows into the squeezing cylinder 7 through the squeezing feed port 79 to clean the inner wall of the squeezing cylinder 7 and the outer surface of the inner filter conveying component 10. Under the action of the baffle plate 103, there is no residue left in the transmission support pipe 100. Finally, the cleaned wastewater is transferred and output through the first water slag receiving plate 83 and the second water slag receiving plate 62.

[0088] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
