[0001] The invention relates to the technical field of corn starch processing, and in particular to corn germ separation equipment. Background Art

[0002] In the process of wet production of corn starch, the germ and endosperm of corn need to be separated, and the germ needs to be dried after separation. In the traditional production process, after the corn is crushed, a separate separator is used to separate the germ and endosperm. Then the separated germ needs to go through a series of processes such as cleaning and dehydration before it can be dried. The whole process has many steps and a long process flow. Each process step requires special equipment, resulting in a large number of equipment and a large floor space, which increases the equipment investment cost. At the same time, since the germ needs to circulate in different equipment, it also reduces production efficiency. Summary of the invention

[0015] The overall structure of the equipment is compact, requires few devices, has a simple structure and high production efficiency.

[0016] After the mixed liquid enters the separation tank, it will rotate. Due to the different densities of the endosperm and the germ, the endosperm with a higher density will be thrown to the inner wall of the separation tank and finally discharged from the bottom; the germ with a lower density will enter the guide cover with the water flow. In this way, the separation of the germ and the endosperm is achieved by utilizing the difference in density, and the separation process is simple.

[0017] The germs can be more concentrated under the action of the guide cover, and will not float on the water surface at will, which is more conducive to the collection of the germs. After the germs enter the conveyor through the guide tube, they are transported from the conveyor to the dryer to achieve solid-liquid separation, cleaning, and dehydration. No additional equipment is required for processing, which reduces production costs and improves production efficiency.

[0018] During the drying process, the germs are in a boiling state in the drying box and can be fully exposed to the hot air, which has a better drying effect. The dried germs are discharged from the top of the drying box along with the hot air, which simplifies the final collection process. BRIEF DESCRIPTION OF THE DRAWINGS

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0036] As attached Figure 1 As shown, the present invention provides a corn germ separation device, comprising a separator 1, and the separator 1 is used to separate the germ and endosperm in the mixed liquid and dehydrate them.

[0037] The discharge end of the separator 1 is fixedly connected to the feed end of the dryer 4 ; the germs separated and dehydrated by the separator 1 enter the dryer 4 and are dried in the dryer 4 .

[0038] The discharge end of the dryer 4 is connected to the air inlet end of the cyclone separator 6 through the first air duct 5, and the air outlet end of the cyclone separator 6 is connected to the induced draft fan 8 through the second air duct 7. The dried germs enter the cyclone separator 6 with the wind to complete the separation, and the final germ collection is completed.

[0039] The structure of the separator 1 is shown in the attached Figure 2 As shown, the separation tank 9 includes an open top, a discharge port 10 is provided at the bottom of the separation tank 9, and a gate valve 11 is installed on the discharge port 10 through a flange. The gate valve 11 is connected to the controller and opened at a fixed time to discharge the endosperm and other materials at the bottom of the separation tank 9.

[0040] As attached Figure 2 , Attachment Figure 3 and attached Figure 4 As shown, an inverted funnel-shaped guide cover 13 is fixedly installed on the upper part of the separation tank 9. A material guide box 14 is fixedly installed on the top of the guide cover 13, and the material guide box 14 is communicated with the guide cover 13.

[0041] A conveyor 16 is also fixedly installed on the top of the separation tank 9 , and the feed end of the conveyor 16 is connected to the material guide box 14 , and a discharge box 17 is fixedly installed on the discharge end of the conveyor 16 , and the discharge box 17 is fixedly connected to the feed end of the dryer 4 .

[0042] A feed pipe 12 is fixedly mounted on the side wall of the separation tank 9, and the feed pipe 12 is located in the middle of the separation tank 9. Figure 2 and attached Figure 3As shown, the feed pipe 12 is tangent to the separation tank 9; the mixed liquid of the endosperm and the germ is pumped into the feed pipe 12 through the delivery pump, and then enters the separation tank 9. Since the feed pipe 12 is tangent to the separation tank 9, the mixed liquid will rotate in the separation tank 9. Since the endosperm is heavy, it will be thrown onto the inner wall of the separation tank 9 and slide along the inner wall of the separation tank 9 to the bottom of the separation tank 9. Since the germ has a relatively high oil content and a relatively low density, it will be entrained by the rising water flow, and after being guided by the guide cover 13, it will enter the guide box 14, and then enter the conveyor 16, and be sent to the dryer 4 by the conveyor 16.

[0043] As attached Figure 4 As shown, the guide cover 13 includes a bell-mouth section 22 and a vertical section 23 fixed on the top of the bell-mouth section 22; the large diameter end of the bell-mouth section 22 is fixedly connected to the inner wall of the separation tank 9, that is, the diameter of the large diameter end of the bell-mouth section 22 is equal to the inner diameter of the separation tank 9; the small diameter end of the bell-mouth section 22 is fixedly connected to the bottom of the vertical section 23, and the top of the vertical section 23 is fixedly connected to the bottom of the guide box 14, and is communicated with the interior of the guide box 14.

[0044] The top of the bell section 22 is flush with the top of the separation tank 9, so that a buffer groove is formed between the inner wall of the separation tank 9 and the outer wall of the bell section 22. A drain port 18 is fixedly installed on the upper part of the separation tank 9, and the drain port 18 is connected to the buffer groove.

[0045] The structure of the aforementioned material guide box 14 is shown in the attached Figure 5 As shown, it includes a lower box body 24 whose bottom is fixedly mounted on the vertical section 23, and an upper box body 26 detachably mounted on the top of the lower box body 24. Specifically, the top of the lower box body 24 is open, and a first flange 25 is fixedly mounted at the top edge, and the bottom of the upper box body 26 is open, and a second flange matching the first flange 25 is fixedly mounted at the bottom edge, and the second flange is fixedly connected to the first flange 25 by bolts. A sealing ring is installed between the second flange and the first flange 25 for sealing.

[0046] A guide tube 27 is fixedly mounted on a side wall of the upper box body 26 . The guide tube 27 is arranged to be tilted downward, and a third flange 28 is fixedly mounted on one end of the guide tube 27 away from the upper box body 26 .

[0047] The top of the upper box 26 is fixedly mounted with a first motor 15 through a motor seat 19, and the axis of the first motor 15 coincides with the axis of the separation tank 9. The output end of the first motor 15 is connected to the first end of the first stirring shaft 21 through a first coupling, and the second end of the first stirring shaft 21 extends into the separation tank 9 and is fixedly mounted with a first fan blade 20.

[0048] The feed pipe 12 is located above the first fan blade 20 .

[0049] The first motor 15 drives the first fan blade 20 to stir the mixed liquid in the separation tank 9, so that the rotation speed of the mixed liquid is faster, thereby accelerating the separation of the endosperm and the germ.

[0050] The conveyor 16 is provided with a first feed port 32, on which a fourth flange matching the third flange 28 is fixedly mounted, and the fourth flange is connected to the third flange 28 by bolts. The fourth flange and the third flange 28 are also sealed by a sealing ring.

[0051] The structure of the conveyor 16 is shown in the attached Figure 6 and attached Figure 7 As shown, it includes a housing, and a central shaft 30 is arranged in the housing. Specifically, the first end of the central shaft 30 passes through the housing and the first bearing seat in sequence, and is connected to the output end of the second motor 29 through a second coupling. The first bearing seat is fixed to the first end of the housing through a first mounting seat. A first auger piece 45 is fixedly mounted on the central shaft 30.

[0052] The second end of the central shaft 30 extends out of the second end of the housing and rotates with the second bearing seat 41. The second bearing seat 41 is fixedly mounted on the discharge box 17 through the second mounting seat 42. The discharge box 17 is fixedly mounted on the second end of the housing. The second end of the housing is open and the first end is closed.

[0053] Two cylinders 38 are fixedly mounted on the second mounting seat 42, and the axes of the two cylinders 38 are parallel to the axis of the central axis 30. The two cylinders 38 are respectively located on both sides of the second bearing seat 41.

[0054] The output end of the cylinder 38 is fixedly connected to the extrusion plate 40, and the extrusion plate 40 is slidably sleeved on the central shaft 30. The extrusion plate 40 can block the second end of the shell under the drive of the cylinder 38. The second end of the shell and the extrusion plate 40 are both located above the discharge box 17, so that the material discharged from the second end of the shell can accurately fall into the discharge box 17.

[0055] A first observation port 31, a first feed port 32, a second observation port 33, and a cleaning port are fixedly installed on the top of the shell in sequence from the first end of the shell to the second end of the shell.

[0056] Among them, the fourth flange is fixedly installed on the first feed port 32.

[0057] In this embodiment, the shell is divided into a filtering section and a dehydration section from the first end to the second end; the first observation port 31, the first feed port 32, and the second observation port 33 are located in the filtering section, and the cleaning port is located in the dehydration section.

[0058] A first filter plate 39 matching the first feed port 32 is fixedly installed at the bottom of the filter section, and the first filter plate 39 is located above the buffer tank. After the water flow carries the germs from the guide box 14 into the first feed port, the water drains out from the third filter plate 44 and enters the buffer tank, and the germs are pushed to the discharge box 17 by the first auger piece 45.

[0059] As attached Figure 6 , Attachment Figure 8 and attached Fig. 9 As shown, a cover plate 34 is installed on the top of the cleaning port by bolts, and a main nozzle 35 is fixedly installed on the top of the cover plate 34. The axis of the main nozzle 35 is parallel to the axis of the central axis 30, and one end of the main nozzle 35 is connected to the water pump 3 through the water pipe 2.

[0060] A plurality of branch pipes are fixedly installed in a linear array at the bottom of the main nozzle 35, each branch pipe is connected to a corresponding sub-nozzle 46 after passing through the cover plate 34, and a plurality of nozzles are provided on the sub-nozzle 46. A third filter plate 44 matching the cleaning port is fixedly installed at the bottom of the dehydration section of the shell.

[0061] When the germ reaches the cleaning port, the clean water sprayed by the sub-spray pipe 46 cooperates with the stirring of the germ by the first auger piece 45 to clean the germ and wash away the starch adhering to the germ. The cleaning water flows away through the third filter plate 44.

[0062] A second filter plate 43 is also fixedly mounted at the bottom of the dehydration section for draining water. The length of the second filter plate 43 is equal to the distance from the end of the third filter plate 44 away from the second motor 29 to the second end of the housing. The second filter plate 43 can prevent the washing water from not being completely drained at the second filter plate 43, which affects the subsequent drying operation.

[0063] As attached Fig. 9 As shown, an extrusion sleeve 47 is also fixedly installed at the second end of the central shaft 30; specifically, the axis of the extrusion sleeve 47 coincides with the axis of the central shaft 30, that is, the extrusion sleeve 47 is sleeved outside the central shaft 30 and fixed by welding. The diameter of the second end of the extrusion sleeve 47 is larger than the diameter of the central shaft 30, and the first end is tapered to achieve a smooth transition between the central shaft 30 and the second end of the extrusion sleeve 47. The second end of the extrusion sleeve 47 faces the extrusion plate 40.

[0064] A second auger piece 48 is fixedly mounted on the extrusion sleeve 47 . The pitch of the second auger piece 48 may be the same as the pitch of the first auger piece 45 , or may be smaller than the pitch of the first auger piece 45 .

[0065] The distance between the squeezing plate 40 and the second end of the housing is adjusted in advance by the cylinder 38, and the first auger piece 45 pushes the germ to the squeezing sleeve 47. Since the distance between the squeezing sleeve 47 and the housing is smaller than the distance between the central axis 30 and the housing, the germ is squeezed; at the same time, the germ is blocked by the squeezing plate 40 when leaving the housing, which further improves the squeezing effect of the squeezing sleeve 47 on the germ, so that the water in the germ is squeezed out. The germ falls into the discharge box 17 through the gap between the housing and the squeezing plate 40, and the squeezed water flows away through the second filter plate 43.

[0066] The dehydration section of the outer shell is also fixedly mounted with a drainage box 36 , and the aforementioned second filter plate 43 and third filter plate 44 are both located in the drainage box 36 .

[0067] In order to prevent the germs from falling from both sides of the discharge box 17 after coming out of the second end of the shell, a U-shaped baffle 37 is fixedly installed on the top of the discharge box 17 .

[0068] The structure of the extrusion plate 40 is shown in the attached Fig.10 As shown, it includes a circular plate body 49 , and a sliding hole 50 is provided in the middle of the plate body 49 to slide with the central shaft 30 .

[0069] A first ear plate 51 and a second ear plate 52 are fixedly mounted on both sides of the plate body 49 , respectively. The second ear plate 52 and the first ear plate 51 are fixedly connected to the output ends of the corresponding cylinders 38 , respectively.

[0070] In this embodiment, the air cylinder 38 may also be replaced by an oil cylinder or an electric cylinder.

[0071] The structure of the aforementioned dryer 4 is shown in the attached Fig.11 As shown, a drying box 53 is included, and a second feed port 54 is fixedly installed on one side of the top of the drying box 53. The second feed port 54 is fixedly connected to the discharge box 17, so that the germs can smoothly enter the drying box 53.

[0072] A horizontal partition 63 is fixedly installed inside the drying box 53, and a plurality of air holes are provided on the partition 63.

[0073] An air inlet 62 is also fixedly installed at the lower part of the drying box 53 . The air inlet 62 is located below the partition 63 and is used to introduce high-pressure hot air into the drying box 53 .

[0074] A plurality of material distribution columns 55 are fixedly installed in the drying box 53 . The plurality of material distribution columns 55 are all located below the second material feed port 54 , and a distance is left between two adjacent material distribution columns 55 .

[0075] In this embodiment, there are four material distribution columns 55, which are arranged in a diamond shape, and each material distribution column 55 has a triangular cross section. After the germs fall from the second feed port 54, they first contact the four material distribution columns 55. The germs that fall in pieces will be broken up by the material distribution columns 55 and can fall more evenly. During the falling process, the germs can contact the high-pressure hot air to achieve drying.

[0076] The drying box 53 is fixedly mounted on the top of the base 58 .

[0077] A second stirring shaft 61 is also installed in the drying box 53. The first end of the second stirring shaft 61 extends to the inside of the base 58 and is fixedly installed with a second pulley 60. The second pulley 60 is connected to the first pulley 59 through a belt. The first pulley 59 is fixedly installed at the output end of the third motor 57. The third motor 57 is also fixedly installed on the base 58.

[0078] The second end of the second stirring shaft 61 extends to the top of the partition 63 and is fixedly mounted with a second fan blade 64. The second fan blade 64 is used to stir the germs falling on the partition 63 to avoid blocking the air holes, and also to make the germs more fully contact with the high-pressure hot air.

[0079] A discharge port 56 is fixedly installed in the middle of the top of the drying box 53, and the discharge port 56 is connected to the cyclone separator 6 through the first air duct 5. The dried germs are discharged from the discharge port 56 along with the air flow, and finally enter the cyclone separator 6 for collection.

[0080] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
