Description

Technical Field

[0001] This invention relates to the field of zeaxanthin extraction technology, specifically to a raw material purification structure for zeaxanthin extraction. Background Technology

[0002] As is well known, in the process of zeaxanthin extraction, the raw material impurity removal structure is a key device for pre-treating raw materials such as corn. Its function is to remove impurities such as soil, stones, weeds, and broken kernels mixed in with the raw materials. This structure usually includes a conveying unit, a screening unit, and an air separation unit. The conveying unit transports the raw materials to the screening unit, where impurities of different sizes are separated by the difference in the mesh size of the screen. The air separation unit separates light impurities by means of airflow buoyancy, providing clean raw materials for subsequent zeaxanthin extraction.

[0003] A search revealed a Chinese patent for a raw material cleaning device for the bio-enzymatic extraction of zeaxanthin, application publication number CN216605601U. This patent includes an inverted L-shaped box and supporting legs. A feed hopper is installed through the top wall of the box. A partition is located in the middle of the lower end of the inner cavity of the box, forming a separation chamber with the lower front part of the inner cavity. A lower cleaning mechanism is located in the lower part of the separation chamber, and a discharge mechanism is located in the upper part of the separation chamber. A receiving box is inserted into the rear wall of the box, and a receiving handle is located on the outer wall of the receiving box. An upper cleaning mechanism is located in the upper part of the box. This invention is particularly suitable for cleaning raw materials for the bio-enzymatic extraction of zeaxanthin and has high social value and application prospects.

[0004] When extracting zeaxanthin, the corn kernels used as raw material for zeaxanthin extraction are treated to remove impurities and prevent them from appearing in subsequent zeaxanthin extraction and processing. The problem with the existing technology is that it lacks a structure to treat the impurities and mold contained in the corn kernels together, thus reducing the flexibility in handling corn impurities and mold. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a raw material impurity removal structure for zeaxanthin extraction, which has the advantage of treating impurities and mold contained in corn kernels together, thus improving the flexibility in treating corn impurities and molds.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a raw material impurity removal treatment structure for zeaxanthin extraction, comprising a sterilization mechanism and a separation mechanism, wherein the separation mechanism is disposed on top of the sterilization mechanism, the sterilization mechanism comprising an air supply component, a collection component, a heating component, a diversion component, and a conveying component, wherein the collection component is disposed on top of the air supply component, the heating component is disposed on top of the collection component, the diversion component is disposed on top of the heating component, and the conveying component is disposed on the top inner side of the collection component; the separation mechanism comprises an introduction component, a transmission component, a guide component, and a sieving component, wherein the introduction component is disposed on top of the collection component, the transmission component is disposed on top of the introduction component, the guide component is disposed inside the transmission component, and the sieving component is disposed inside the guide component.

[0007] By adopting the above technical solution, a sterilization mechanism and a separation mechanism are set up. The sterilization mechanism can heat the air and blow the heated air to the corn kernels, thereby blowing away impurities inside the corn kernels. At the same time, the high temperature can kill the mold on the surface of the corn kernels. The separation mechanism can use centrifugal force to throw out the impurities in the corn kernels, achieving the effect of separating the impurities in the corn kernels. It can also cooperate with the sterilization mechanism to use the hot air delivered by the sterilization mechanism to further separate and clean the impurities and mold in the corn kernels.

[0008] The present invention is further configured such that: the air supply assembly includes a support base, an air pump and a guide pipe, the air pump is located on the top of the support base, and the guide pipe is connected to the output end of the top of the air pump.

[0009] By adopting the above technical solution, by setting up an air delivery component, the support base can cooperate with the air pump and the guide pipe. The support base provides support for the air pump, allowing the air pump to support the guide pipe with the support base as the support point. Thus, when the air pump is pumping air, it can deliver air from the guide pipe to the drainage pipe.

[0010] The present invention is further configured such that: the collection component includes a fixed bracket, a recycling box and a box door, the fixed bracket is fixedly connected to the top of the support base, the recycling box is fixedly connected to the top of the fixed bracket, and the box door is located on the front side of the recycling box.

[0011] By adopting the above technical solution, by setting up the collection component, the fixed bracket can be used in conjunction with the recycling box and the box door. The storage structure formed by the fixed bracket, the recycling box and the box door can provide operating space for the air pump between the recycling box and the support base when the fixed bracket supports the recycling box with the support base as the support point. The recycling box can store the corn kernels sent out from the collection cylinder, and the corn kernels can be removed by opening the box door for subsequent zeaxanthin extraction operations.

[0012] The present invention is further configured such that: the heating component includes an electric heater, a drain pipe and an inclined exhaust port, the electric heater is fixedly connected to the surface of the drain pipe, the drain pipe is connected to the top of the electric heater, the surface of the drain pipe is fixedly connected to the inner side of the recycling box, the inclined exhaust port is opened on the surface of the drain pipe, and the bottom of the inclined exhaust port is close to the bottom of the inner side of the recycling box.

[0013] By adopting the above technical solution, and by setting up a heating component, the electric heater can cooperate with the drainage pipe and the inclined exhaust port. Through the air guiding and heating structure formed by the electric heater, the drainage pipe and the inclined exhaust port, the air in the drainage pipe can be heated by the electric heater, providing the drainage pipe with preheated hot air. The inclined exhaust port is a downward-sloping exhaust structure. When the drainage pipe is filled with air and positive pressure is generated, the air can flow to the bottom of the recycling box through the inclined design of the inclined exhaust port, so that it can directly contact the corn kernels stored in the recycling box for further drying. At the same time, the electric heater can provide heat to the heat conduction rod.

[0014] The present invention is further configured such that: the flow guiding assembly includes a heat-conducting rod, an exhaust pipe, and a spiral guide plate; the bottom surface of the heat-conducting rod is fixedly connected to the output end inside the electric heater through the guide pipe; the exhaust pipe is connected to the top of the flow guiding pipe; the spiral guide plate is fixedly connected to the top of the surface of the heat-conducting rod; and the surface of the spiral guide plate is in contact with the inner side of the exhaust pipe.

[0015] By adopting the above technical solution, and by setting up the air diversion component, the heat-conducting rod can cooperate with the exhaust pipe and the spiral guide plate. The heat-conducting rod, together with the exhaust pipe and the spiral guide plate, can form an air transport structure for guiding and heating air. The heat from the electric heater can be transferred to the exhaust pipe through the spiral guide plate. Through the air homogenization transport structure formed by the exhaust pipe and the spiral guide plate, the spiral design of the spiral guide plate can transport air upward in a spiral shape to all parts of the exhaust pipe. This allows the air to be evenly discharged from the holes of the exhaust pipe along the spiral guide plate, thereby achieving uniform air delivery into the interception net and improving the stability of the air when it is blown to the corn kernels.

[0016] The present invention is further configured such that: the conveying assembly includes a collection cylinder, an adjusting motor and an arc-shaped cover plate; the collection cylinder is fixedly connected to the top of the inner side of the recycling box; the adjusting motor is fixedly connected to the front side of the collection cylinder; the arc-shaped cover plate is fixedly connected to the output end on the right side of the adjusting motor; the top of the arc-shaped cover plate contacts the bottom of the collection cylinder; and the inner side of the arc-shaped cover plate contacts the top of the surface of the drainage pipe.

[0017] By adopting the above technical solution, and by setting up a conveying component, the collecting cylinder can cooperate with the regulating motor and the arc-shaped cover plate. The temporary corn kernel collecting structure formed by the collecting cylinder, the regulating motor, and the arc-shaped cover plate can be adjusted by rotating the arc-shaped cover plate downwards, thereby opening the collecting cylinder and allowing the corn kernels to fall from the collecting cylinder into the recycling box. The temporary corn kernel storage structure formed by the arc-shaped cover plate, the collecting cylinder, and the drainage pipe can provide a stable separation space for the corn kernels, facilitating the separation of impurities and mold contained within the corn kernels as they move with the arc-shaped separation mesh plate.

[0018] The present invention is further configured such that: the introducing component includes a fixed ring base, a limiting outer shell barrel, and a feeding funnel; the fixed ring base is fixedly connected to the top of the recycling box; the limiting outer shell barrel is fixedly connected to the top of the fixed ring base; and the feeding funnel communicates with the top of the limiting outer shell barrel.

[0019] By adopting the above technical solution, the fixed ring base can cooperate with the limiting outer shell and the feeding funnel by setting the introduction component. The fixed ring base supports the limiting outer shell with the top of the recycling box as the support point, so that the limiting outer shell and the feeding funnel can form a temporary storage for the raw corn kernels from which zeaxanthin is extracted, thereby providing the space required for the separation of corn kernels. In addition, the limiting outer shell can temporarily store the separated impurities and mold.

[0020] The present invention is further configured such that: the transmission assembly includes a positioning housing, a transmission motor and a gear ring assembly; the positioning housing is fixedly connected to the top of the limiting housing barrel; the transmission motor is fixedly connected to the left side of the top of the positioning housing; the gear ring assembly is located inside the positioning housing; and the output end of the bottom of the transmission motor passes through the positioning housing and is fixedly connected to the left side of the top of the gear ring assembly.

[0021] By adopting the above technical solution, the positioning housing can cooperate with the drive motor and gear ring assembly by setting the transmission component. The positioning housing can limit the movement of the drive motor and gear ring assembly. The gear ring assembly is a transmission structure formed by a gear and a gear ring. The gear is located at the output end of the bottom of the drive motor, and the gear ring is located at the center of the positioning housing. The gear and the gear ring mesh with each other. When the drive motor drives the gear to rotate the gear ring, the gear ring can drive the inlet pipe to rotate, thereby providing the centrifugal force required for separation of the inlet pipe.

[0022] The present invention is further configured such that: the guiding component includes a feeding pipe, an intercepting mesh cover, and an inlet pipe; the surface of the inlet pipe is fixedly connected to the inner side of the gear ring assembly away from the output end of the transmission motor; the intercepting mesh cover is connected to the bottom of the inlet pipe; the feeding pipe is connected to the bottom of the intercepting mesh cover; and the bottom of the feeding pipe is close to the top of the collecting cylinder.

[0023] By adopting the above technical solution, and by setting up a guiding component, the feeding pipe can cooperate with the intercepting net and the inlet pipe. The feeding pipe, the intercepting net, and the inlet pipe form a corn kernel conveying and centrifugal force generating structure. As the gear ring group rotates, the inlet pipe drives the intercepting net and the feeding pipe to rotate axially together. The centrifugal force generated by the axial rotation can throw the impurities in the corn kernels from the intercepting net into the limiting outer casing for temporary storage.

[0024] The present invention is further configured such that: the screening component includes an assembled arc-shaped frame, an arc-shaped separation mesh plate, and a guide support rod; the assembled arc-shaped frame is fixedly connected to the inner side of the interception mesh cover; the arc-shaped separation mesh plate is fixedly connected to the inner side of the assembled arc-shaped frame; and the guide support rod is fixedly connected to the inner side of the arc-shaped separation mesh plate.

[0025] By adopting the above technical solution, and by setting up a screening component, the assembled arc-shaped frame can cooperate with the arc-shaped separation screen and guide support rod. Through the corn kernel guiding structure composed of the assembled arc-shaped frame, the arc-shaped separation screen and guide support rod, the arc-shaped design of the arc-shaped separation screen itself allows the corn kernels to gradually move towards the center along the arc-shaped design of the arc-shaped separation screen surface due to inertia when the intercepting screen rotates counterclockwise. They gradually disperse on the surface of the arc-shaped separation screen and then gradually accumulate on the surface of the intercepting screen due to centrifugal force. This avoids the corn kernels from immediately accumulating on the surface of the intercepting screen and blocking impurities between the corn kernels. Furthermore, by repeatedly changing its rotation direction, the efficiency of separating impurities and mold from the corn kernels can be improved.

[0026] Compared with the prior art, the present invention provides a raw material impurity removal treatment structure for zeaxanthin extraction, which has the following beneficial effects: This raw material impurity removal structure for zeaxanthin extraction incorporates a sterilization mechanism. The air delivery component works in conjunction with a collection component, a heating component, a drainage component, and a conveying component. An air pump and a guide pipe form an air delivery structure, allowing outside air to be transported to the drainage pipe. A corn kernel storage structure, formed by a recovery box and its door, stores the corn kernels that have undergone impurity removal. An air heating and conveying guide structure, consisting of an electric heater, the drainage pipe, and a sloping exhaust vent, heats the air inside the drainage pipe and the heat-conducting rod. The sloping exhaust vent, creating positive pressure inside the drainage pipe, blows air towards the corn kernels in the recovery box, thus improving the quality of the corn kernels. The rice grains undergo further drying. Through an air guiding and impurity blowing structure consisting of an exhaust pipe, a heat-conducting rod, and a spiral guide plate, the heat-conducting rod further transfers temperature to the exhaust pipe and spiral guide plate, heating the passing air. The air is then evenly delivered to the corn kernels where impurities need to be separated through the spiral structure of the spiral guide plate, thereby blowing away impurities and mold from the corn kernels. At the same time, the high temperature can kill the mold. The temporary storage structure for corn kernels, consisting of a collection cylinder, an adjusting motor, and an arc-shaped cover plate, can prevent corn kernels from accidentally falling into the recycling box during the impurity removal and mold elimination process, thus increasing the stability of the corn kernels during the impurity removal and mold elimination process. This raw material impurity removal structure for zeaxanthin extraction utilizes a separation mechanism. The inlet component can be used in conjunction with the transmission component, guide component, and sieve component. A temporary space structure for handling corn kernel impurities and eliminating mold, formed by a limiting outer shell and a feeding funnel, provides this necessary space. A transmission structure, consisting of a positioning outer shell, a drive motor, and a gear ring assembly, provides the centrifugal power required for the inlet pipe when the drive motor rotates the gear ring assembly. The corn kernel centrifugal impurity separation structure, composed of a feeding pipe, an intercepting screen, and the inlet pipe, can cooperate with a corn kernel dispersion structure consisting of an assembled arc-shaped frame, an arc-shaped separation screen, and guide support rods. Through repeated clockwise and counterclockwise axial rotation of the gear ring assembly, the corn kernels are evenly distributed on the arc-shaped separation screen. The centrifugal force generated by the rotating intercepting screen separates impurities and mold from the corn kernels. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0030] Please see Figure 1-7A raw material purification structure for zeaxanthin extraction includes a sterilization mechanism 1. The sterilization mechanism 1 comprises an air supply component 11, a collection component 12, a heating component 13, a diversion component 14, and a conveying component 15. The collection component 12 is located on top of the air supply component 11, the heating component 13 is located on top of the collection component 12, the diversion component 14 is located on top of the heating component 13, and the conveying component 15 is located on the top inner side of the collection component 12. By providing the sterilization mechanism 1, the air supply component 11 can interact with the collection component 12. The assembly, consisting of component 12, heating component 13, diversion component 14, and conveying component 15, works together. An air pump 112 and guide pipe 113 form an air conveying structure, allowing outside air to be delivered to the diversion pipe 132 via the guide pipe 113. A corn kernel storage structure formed by the recovery box 122 and box door 123 stores corn kernels that have undergone impurity treatment. An air heating and conveying guiding structure, consisting of an electric heater 131, the diversion pipe 132, and the inclined exhaust port 133, further enhances the air heating and conveying capabilities. The air inside the drainage pipe 132 can be heated, as can the heat-conducting rod 141. When a positive pressure is formed inside the drainage pipe 132, the inclined exhaust port 133 can blow air towards the corn kernels in the recycling box 122 to further dry the corn kernels. Through the air guiding and impurity blowing structure composed of the exhaust pipe 142, the heat-conducting rod 141, and the spiral guide plate 143, the heat-conducting rod 141 can further transfer the temperature to the exhaust pipe 142 and the spiral guide plate 143, heating the passing air. The air is then evenly delivered to the corn kernels where impurities need to be separated through the spiral structure of the spiral guide plate 143, thereby blowing away impurities and mold from the corn kernels. At the same time, high temperature can be used to kill the mold. The temporary corn kernel storage structure composed of the collection cylinder 151, the regulating motor 152, and the arc-shaped cover plate 153 can prevent corn kernels from accidentally falling into the recycling box 122 during the removal of impurities and the elimination of mold, thereby increasing the stability of the corn kernels during the removal of impurities and the elimination of mold.

[0031] The air delivery assembly 11 includes a support base 111, a vacuum pump 112, and a guide pipe 113. The vacuum pump 112 is located on the top of the support base 111, and the guide pipe 113 is connected to the output end of the top of the vacuum pump 112. By setting the air delivery assembly 11, the support base 111 can cooperate with the vacuum pump 112 and the guide pipe 113. The support base 111 provides support for the vacuum pump 112, allowing the vacuum pump 112 to support the guide pipe 113 with the support base 111 as the support point. Thus, when the vacuum pump 112 is pumping air, it can deliver air from the guide pipe 113 to the drainage pipe 132.

[0032] The collection component 12 includes a fixed bracket 121, a recycling box 122, and a box door 123. The fixed bracket 121 is fixedly connected to the top of the support base 111, the recycling box 122 is fixedly connected to the top of the fixed bracket 121, and the box door 123 is located on the front side of the recycling box 122. By setting the collection component 12, the fixed bracket 121 can be used in conjunction with the recycling box 122 and the box door 123. Through the storage structure formed by the fixed bracket 121, the recycling box 122, and the box door 123, when the fixed bracket 121 supports the recycling box 122 with the support base 111 as the support point, the space between the recycling box 122 and the support base 111 provides operating space for the vacuum pump 112. The recycling box 122 can store the corn kernels sent out from the collection cylinder 151, and the corn kernels can be removed by opening the box door 123 for subsequent zeaxanthin extraction operations.

[0033] The heating component 13 includes an electric heater 131, a drain pipe 132, and a sloping exhaust port 133. The electric heater 131 is fixedly connected to the surface of the drain pipe 113. The drain pipe 132 is connected to the top of the electric heater 131, and the surface of the drain pipe 132 is fixedly connected to the inner side of the recycling box 122. The sloping exhaust port 133 is opened on the surface of the drain pipe 132, and the bottom of the sloping exhaust port 133 is close to the bottom of the inner side of the recycling box 122. By setting the heating component 13, the electric heater 131 can cooperate with the drain pipe 132 and the sloping exhaust port 133. The air guiding and heating structure composed of 32 and the inclined exhaust port 133 can heat the air in the guide pipe 132 through the electric heater 131, and can provide the guide pipe 132 with preheated hot air. The inclined exhaust port 133 is a downward sloping exhaust structure. When the guide pipe 132 is filled with air and positive pressure is generated, the air can flow through the inclined design of the inclined exhaust port 133 to the bottom of the recycling box 122, so that it can directly contact the corn kernels stored in the recycling box 122 for further drying. At the same time, the electric heater 131 can provide heat to the heat conduction rod 141.

[0034] The heat-conducting assembly 14 includes a heat-conducting rod 141, an exhaust pipe 142, and a spiral guide plate 143. The bottom surface of the heat-conducting rod 141 passes through the guide pipe 113 and is fixedly connected to the output end inside the electric heater 131. The exhaust pipe 142 is connected to the top of the heat-conducting pipe 132. The spiral guide plate 143 is fixedly connected to the top surface of the heat-conducting rod 141, and the surface of the spiral guide plate 143 contacts the inner side of the exhaust pipe 142. By setting the heat-conducting assembly 14, the heat-conducting rod 141 can cooperate with the exhaust pipe 142 and the spiral guide plate 143. The paired air guiding and heating air delivery structure can be heated by the electric heater 131 through the heat-conducting rod 141, and the heat is delivered to the exhaust pipe 142 through the spiral guide plate 143. The air homogenization delivery structure formed by the exhaust pipe 142 and the spiral guide plate 143 can deliver the air upward in a spiral shape to all parts of the exhaust pipe 142 through the spiral design of the spiral guide plate 143. This allows the air to be evenly discharged from the holes of the exhaust pipe 142 along the spiral guide plate 143, thereby achieving uniform delivery of air into the intercepting mesh cover 232 and improving the stability of the air when it is blown to the corn kernels.

[0035] The conveying assembly 15 includes a collection cylinder 151, an adjusting motor 152, and an arc-shaped cover plate 153. The collection cylinder 151 is fixedly connected to the top of the inner side of the recycling box 122. The adjusting motor 152 is fixedly connected to the front side of the collection cylinder 151. The arc-shaped cover plate 153 is fixedly connected to the output end on the right side of the adjusting motor 152. The top of the arc-shaped cover plate 153 contacts the bottom of the collection cylinder 151, and the inner side of the arc-shaped cover plate 153 contacts the top of the surface of the drainage pipe 132. By setting the conveying assembly 15, the collection cylinder 151 can cooperate with the adjusting motor 152 and the arc-shaped cover plate 153 to collect and transport materials. The temporary corn kernel collection structure, consisting of the collecting cylinder 151, the regulating motor 152, and the arc-shaped cover plate 153, can open the collecting cylinder 151 by rotating the arc-shaped cover plate 153 downwards, allowing the corn kernels to fall from the collecting cylinder 151 into the recycling box 122. The temporary corn kernel storage structure formed by the arc-shaped cover plate 153, the collecting cylinder 151, and the drainage pipe 132 can provide a stable separation space for the corn kernels, facilitating the separation of impurities and mold contained within the corn kernels as they move with the arc-shaped separation mesh plate 242.

[0036] The working principle of this embodiment is as follows: First, the air pump 112, electric heater 131, and regulating motor 152 are connected to an external PLC controller and power supply, and then powered on and started. Under the control of the PLC controller, the regulating motor 152 drives the arc-shaped cover plate 153 to rotate, rotating the arc-shaped cover plate 153 towards the collecting cylinder 151 until the bottom of the collecting cylinder 151 is closed by the arc-shaped cover plate 153. The electric heater 131 then heats the drain pipe 132 and the heat-conducting rod 141, and the heat-conducting rod 141 transfers heat to the exhaust pipe 142 and the spiral guide plate 143, thereby heating the surrounding air. Then, the air pump 112 draws the outside air to the guide pipe 113, and the air enters the drain pipe through the guide pipe 113. 132, and then along the guide pipe 132 into the exhaust pipe 142, and gradually discharged from the hole in the exhaust pipe 142 into the interception net cover 232 along the spiral guide plate 143. When it is necessary to remove the corn kernels after the impurities have been separated, the adjusting motor 152 will drive the arc cover plate 153 to rotate downward, and the arc cover plate 153 will move away from the collection cylinder 151. At this time, the corn kernels will fall into the recycling box 122 through the collection cylinder 151. Then, hot air will be blown to the corn kernels through the inclined exhaust port 133 to dry the corn kernels a second time. After the corn kernels are dried, the air pump 112 and the electric heater 131 will be turned off. After the corn kernels have cooled down, the box door 123 will be opened and the corn kernels can be taken out. Example

[0037] refer to Figure 8-12A raw material impurity removal structure for zeaxanthin extraction further includes a separation mechanism 2. The separation mechanism 2 includes an inlet component 21, a transmission component 22, a guide component 23, and a sieving component 24. The inlet component 21 is located on top of the collection component 12, the transmission component 22 is located on top of the inlet component 21, the guide component 23 is located inside the transmission component 22, and the sieving component 24 is located inside the guide component 23. By setting the separation mechanism 2, the inlet component 21 can be used in conjunction with the transmission component 22, the guide component 23, and the sieving component 24. The temporary space structure for corn kernel impurity treatment and mold elimination, formed by the limiting outer shell 212 and the feeding funnel 213, provides temporary space for impurity treatment and mold elimination for the corn kernels. In the meantime, the transmission structure consisting of the positioning shell 221, the drive motor 222, and the gear ring assembly 223 provides the power required for centrifugation to the inlet pipe 233 when the drive motor 222 drives the gear ring assembly 223 to rotate. The corn kernel centrifugal impurity separation structure consisting of the feeding pipe 231, the intercepting mesh cover 232, and the inlet pipe 233 can cooperate with the corn kernel dispersion structure consisting of the assembled arc frame 241, the arc separation mesh plate 242, and the guide support rod 243. With the axial rotation of the gear ring assembly 223, which is repeatedly adjusted clockwise and counterclockwise, the corn kernels are evenly distributed on the arc separation mesh plate 242. The centrifugal force generated when the intercepting mesh cover 232 rotates separates the impurities and mold from the corn kernels.

[0038] The introducing component 21 includes a fixed ring base 211, a limiting outer shell 212, and a feeding funnel 213. The fixed ring base 211 is fixedly connected to the top of the recycling box 122, the limiting outer shell 212 is fixedly connected to the top of the fixed ring base 211, and the feeding funnel 213 is connected to the top of the limiting outer shell 212. By setting the introducing component 21, the fixed ring base 211 can cooperate with the limiting outer shell 212 and the feeding funnel 213. The fixed ring base 211 supports the limiting outer shell 212 with the top of the recycling box 122 as the support point, allowing the limiting outer shell 212 and the feeding funnel 213 to temporarily store the raw corn kernels from which zeaxanthin is extracted, thereby providing the space required for the separation of corn kernels. In addition, the limiting outer shell 212 can temporarily store the separated impurities and mold.

[0039] The transmission assembly 22 includes a positioning housing 221, a transmission motor 222, and a gear ring assembly 223. The positioning housing 221 is fixedly connected to the top of the limiting housing 212. The transmission motor 222 is fixedly connected to the left side of the top of the positioning housing 221. The gear ring assembly 223 is located inside the positioning housing 221. The output end of the bottom of the transmission motor 222 passes through the positioning housing 221 and is fixedly connected to the left side of the top of the gear ring assembly 223. By setting the transmission assembly 22, the positioning housing 221 can cooperate with the transmission motor 222 and the gear ring assembly 223. The positioning housing 221 can limit the transmission motor 222 and the gear ring assembly 223. The gear ring assembly 223 is a transmission structure formed by a gear and a gear ring. The gear is located at the output end of the bottom of the transmission motor 222, and the gear ring is located at the center of the positioning housing 221. The gear and the gear ring mesh with each other. When the transmission motor 222 drives the gear to rotate the gear ring, the gear ring can drive the inlet pipe 233 to rotate, thereby providing the centrifugal force required for separation of the inlet pipe 233.

[0040] The guiding component 23 includes a feeding pipe 231, an intercepting net cover 232, and an inlet pipe 233. The surface of the inlet pipe 233 is fixedly connected to the inner side of the gear ring assembly 223 away from the output end of the transmission motor 222. The intercepting net cover 232 is connected to the bottom of the inlet pipe 233, and the feeding pipe 231 is connected to the bottom of the intercepting net cover 232. The bottom of the feeding pipe 231 is close to the top of the collecting cylinder 151. By setting the guiding component 23, the feeding pipe 231 can cooperate with the intercepting net cover 232 and the inlet pipe 233 to form a corn kernel conveying and centrifugal force generating structure. As the gear ring assembly 223 rotates, the inlet pipe 233 drives the intercepting net cover 232 and the feeding pipe 231 to rotate axially together. The centrifugal force generated by the axial rotation can throw the impurities in the corn kernels from the intercepting net cover 232 into the limiting outer casing 212 for temporary storage.

[0041] The screening component 24 includes an assembled arc-shaped frame 241, an arc-shaped separation screen 242, and a guide support rod 243. The assembled arc-shaped frame 241 is fixedly connected to the inner side of the intercepting mesh cover 232, the arc-shaped separation screen 242 is fixedly connected to the inner side of the assembled arc-shaped frame 241, and the guide support rod 243 is fixedly connected to the inner side of the arc-shaped separation screen 242. By setting the screening component 24, the assembled arc-shaped frame 241 can cooperate with the arc-shaped separation screen 242 and the guide support rod 243 to form a corn kernel. The guiding structure, through the arc design of the arc-shaped separation screen plate 242 itself, allows the corn kernels to gradually move towards the center along the arc design of the arc-shaped separation screen plate 242 surface as the intercepting screen 232 rotates counterclockwise, freeing them from centrifugal force. They gradually disperse on the surface of the arc-shaped separation screen plate 242 and then gradually accumulate on the surface of the intercepting screen 232 due to centrifugal force. This prevents the corn kernels from immediately accumulating on the surface of the intercepting screen 232 and blocking impurities between the kernels. Furthermore, the intercepting screen 232 can repeatedly change its rotation direction to improve the efficiency of separating impurities and mold from the corn kernels.

[0042] The working principle of this embodiment is as follows: First, the drive motor 222 is connected to an external PLC controller and powered on and started. Then, the corn kernels from which the zeaxanthin is to be extracted are placed into the feeding funnel 213. The corn kernels then enter the intercepting mesh cover 232 through the feeding funnel 213, where they are blocked and temporarily stopped by the collecting cylinder 151 and the arc-shaped cover plate 153. Then, the PLC controller controls the drive motor 222, which drives the gear ring assembly 223 to rotate the inlet pipe 233 clockwise. The inlet pipe 233 then drives the intercepting mesh cover 232 and the feeding pipe 231 to rotate the assembled arc-shaped frame 241 and the arc-shaped separation mesh plate 242 clockwise together. Then the corn kernels will accumulate between the inner side of the interception mesh cover 232 and the arc-shaped separation mesh plate 242. At this time, the drive motor 222 stops rotating clockwise and starts rotating counterclockwise under the control of the PLC controller. The corn kernels will gradually spread on the surface of the arc-shaped separation mesh plate 242 due to inertia, and the impurities on the surface will be thrown to the limiting outer shell 212 by centrifugal force. At the same time, the high-temperature airflow delivered through the exhaust pipe 142 will blow the impurities on the surface of the corn kernels to the limiting outer shell 212, and use the high temperature to kill the mold on the surface of the corn kernels. The mold will move into the limiting outer shell 212 with the airflow until the impurities are separated and the mold is killed.
