[0002] The insect protein cryogenic extraction device is a specialized piece of equipment meticulously crafted using advanced cryogenic physical processes. It can penetrate deep into insect tissues under precisely controlled cryogenic conditions to extract proteins efficiently while maximizing their bioactivity. Its core advantages are significant: the cryogenic environment acts like a "protective shield" for the proteins, effectively preventing denaturation and inactivation, ensuring superior protein quality. Simultaneously, the device cleverly combines physical methods with a specific process flow to precisely separate oils and proteins, resulting in purer extracted proteins. This innovative equipment provides a reliable guarantee for the high-quality extraction and utilization of insect proteins and has broad application prospects in related fields.

[0003] Currently, existing low-temperature insect protein extraction devices face a significant challenge in practical applications. Because insect raw materials are widely available, they often contain large impurities such as insect exoskeleton fragments and soil particles. These impurities easily accumulate in critical components like pipes and filters during operation, leading to blockages. Once blockages occur, they not only disrupt the normal production process but also significantly reduce equipment efficiency and increase production costs. Summary of the Invention

[0004] In view of the problems in related technologies, the present invention proposes a low-temperature extraction device for insect proteins to overcome the aforementioned technical problems existing in the existing related technologies.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to a low-temperature extraction device for insect protein, comprising an operating box, which serves as the main frame of the entire device, providing a stable space for the installation and operation of various components. A feed inlet is fixedly connected to the top of the operating box; the feed inlet is rationally designed to facilitate the smooth input of insect raw materials. A filter screen, made of high-quality material, is installed below the feed inlet, possessing excellent filtration performance and effectively intercepting impurities and large particles in the insect raw materials. The filter screen is rotatably mounted inside the filter box; rotation enhances the filtration effect and prevents clogging. The lower part of the filter screen contacts the protruding end of a cam; the cam's precise design and the contact method between its protruding end and the filter screen enable regular vibration of the filter screen. The cam is fixedly mounted on a connecting shaft, which is strong and stable, providing reliable support for the cam's rotation. The connecting shaft is fixedly connected to the output end of a drive motor; the drive motor is powerful and can stably output power to drive the connecting shaft to rotate. One end of the connecting shaft is connected to a first gear via a transmission mechanism, which controls the rotation of the first gear, ensuring the accuracy and stability of power transmission. The first gear meshes with a second gear, and the second gear cooperates with the first gear to further transmit and convert power. The second gear is fixedly mounted on the centrifuge drum, which is made of a special material capable of withstanding the centrifugal force generated by high-speed rotation. The centrifuge drum has several filter holes, which are evenly distributed and reasonably sized to facilitate the rapid filtration of the insect protein solution. A lid is provided on the top of the centrifuge drum, which has good sealing performance and can effectively prevent the solution from leaking during centrifugation. The lid is fixedly mounted on the bottom of the filter box, and the lid has a discharge port that is connected to the filter box to ensure that the filtered material can smoothly enter the centrifuge drum. A cleaning brush is rotatably mounted on the lid. The cleaning brush is soft and elastic, fits against the inner wall of the filter box, and can clean the inner wall of the filter box during rotation to prevent impurities from remaining.

[0006] Furthermore, the filter screen is designed with an inclined orientation, which facilitates the automatic downward sliding and discharge of filtered impurities under gravity. The connecting shaft is rotatably mounted inside the filter box, ensuring stable rotation and reducing friction and wear. The drive motor is fixedly mounted on the control box, providing a stable mounting position. The filter box is fixedly mounted inside the control box, forming a unified whole and enhancing the stability of the device.

[0007] Furthermore, the inclined direction of the filter screen extends through both the filter screen and the control box, facilitating the smooth discharge of impurities. A discharge port is provided along the inclined direction of the filter screen; the discharge port is rationally designed and of appropriate size to ensure rapid discharge of impurities. The discharge port is located on both the control box and the filter box, enabling communication between the two. A collection box is located below the discharge port; the collection box has a suitable capacity to collect the filtered impurities. The collection box is fixedly installed on the control box to prevent movement during device operation.

[0008] Furthermore, the transmission mechanism includes a worm gear fixedly mounted on a connecting shaft. The worm gear has high precision and high transmission efficiency. The worm gear meshes with a worm wheel, and the worm wheel and worm gear cooperate to achieve power reduction and steering. The worm wheel is fixedly mounted on a rotating shaft, which provides support for the rotation of the worm wheel. The rotating shaft is fixedly mounted on a first gear, transmitting the rotation of the worm wheel to the first gear. The first gear is rotatably mounted on a connecting plate, which provides a stable mounting base for the first gear. The connecting plate is fixedly mounted inside the operating box to enhance its stability.

[0009] Furthermore, the second gear is rotatably mounted on the connecting plate to ensure stable rotation. The second gear meshes with a third gear, which cooperates with the second gear to further transmit and convert power. The third gear is rotatably mounted on the connecting plate, providing rotational support. The third gear is fixedly mounted with a reciprocating threaded rod, which has a unique design enabling reciprocating motion.

[0010] Furthermore, the reciprocating threaded rod is threadedly connected to a cleaning scraper. The cleaning scraper cooperates with the reciprocating threaded rod and performs reciprocating motion under the drive of the reciprocating threaded rod. The cleaning scraper is slidably connected inside the operating box to ensure stable sliding. The cleaning scraper is in close contact with the inner wall of the operating box, and can clean the inner wall of the operating box during the reciprocating motion to prevent insect protein residue.

[0011] Furthermore, the bottom of the operating box is provided with a discharge port, which is reasonably designed to facilitate the smooth discharge of extracted insect protein. The bottom of the operating box is fixedly equipped with support legs, which are of high strength and can stably support the entire device. Four support legs are provided, evenly distributed at the bottom of the operating box, enhancing the stability of the device.

[0012] Furthermore, the control box is equipped with a rotatable door, which is easy to open and facilitates inspection and maintenance of the device's interior. The control box also has a fixed control panel, which is user-friendly and allows for precise control of all device functions. The control box contains a high-precision temperature control component that accurately controls the temperature inside the box, meeting the requirements for low-temperature extraction of insect proteins.

[0013] Compared with the prior art, the present invention has the following advantages: 1. This device features a rotatable filter plate with an inclined design that allows impurities to automatically slide down and be discharged under gravity. A cam mechanism causes the filter plate to vibrate regularly, enhancing the filtration effect and preventing clogging. Simultaneously, the cleaning brush, during its rotation, cleans the inner wall of the filter chamber to prevent impurities from remaining. Furthermore, when in contact with the filter plate, it squeezes any remaining material, further expelling any residual insect protein solution. In addition, a reciprocating threaded rod drives a cleaning scraper in a reciprocating motion, cleaning the inner wall of the operating chamber and preventing insect protein residue. These design features work together to effectively improve the extraction rate of insect protein.

[0014] 2. The device employs a worm gear transmission mechanism for power reduction and steering, and then transmits power through gear meshing, enabling the centrifuge tank, cleaning brush, cleaning scraper, and other components to work together. This transmission structure boasts high precision and efficiency, ensuring stable operation of the device. Furthermore, the device features a discharge port at the bottom for easy removal of extracted insect protein, support legs for stable support of the entire unit, a convenient door for inspection and maintenance, a control panel for precise control of various functions, and a temperature control component for accurate temperature control within the operating chamber, meeting the requirements for low-temperature extraction of insect protein.

Detailed Implementation

[0019] The technical solutions of the embodiments of the invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the invention.

[0020] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the invention.

[0021] Please see Figures 1-7As shown, this invention is a low-temperature extraction device for insect protein, including an operating box 1. The operating box 1 serves as the main frame of the entire device, providing a stable installation and operating space for all components. A feed inlet 2 is fixedly connected to the top of the operating box 1. The feed inlet 2 is rationally designed with a moderate opening size, facilitating the smooth input of insect raw materials into the device. A filter screen 3 is installed below the feed inlet 2. The filter screen 3 is made of high-quality materials and has excellent filtration performance, effectively intercepting impurities and large particles in the insect raw materials. The filter screen 3 is rotatably installed inside the filter box 4. Rotation enhances the filtration effect and prevents clogging. The lower part of the filter screen 3 contacts the protruding end of a cam 5. The cam 5 has a precise shape design, and the contact between its protruding end and the filter screen 3 enables the filter screen 3 to vibrate regularly. The cam 5 is fixedly installed on a connecting shaft 6. The connecting shaft 6 has high strength and good stability, providing reliable support for the rotation of the cam 5. The connecting shaft 6 is fixedly connected to the output end of a drive motor 7. The drive motor 7 has strong power and can stably output power to drive the connecting shaft 6 to rotate. One end of the connecting shaft 6 is connected to the first gear 8 via a transmission mechanism. The transmission mechanism controls the rotation of the first gear 8, ensuring the accuracy and stability of power transmission. The first gear 8 meshes with a second gear 9, which cooperates with the first gear 8 to further transmit and convert power. The second gear 9 is fixedly mounted on the centrifuge tank 10, which is made of a special material capable of withstanding the centrifugal force generated by high-speed rotation. The centrifuge tank 10 has several filter holes 11, which are evenly distributed and reasonably sized to facilitate the rapid filtration of insect protein solutions. A lid 12 is provided on the top of the centrifuge tank 10. The lid 12 has good sealing performance and can effectively prevent leakage of the solution during centrifugation. The lid 12 is fixedly mounted below the filter box 4 and has a discharge port 27 connected to the filter box 4 to ensure that the filtered material can smoothly enter the centrifuge tank 10. The lid 12 is equipped with a cleaning brush 13 that rotates. The cleaning brush 13 is soft and elastic and fits against the inner wall of the filter box 4. It can clean the inner wall of the filter box 4 during rotation to prevent impurities from remaining.

[0022] The working principle of the low-temperature insect protein extraction device proposed in this invention is as follows: During operation, the insect raw material is first fed into the device through the feed inlet 2, which is fixedly connected to the top of the operating box 1. After entering, the raw material falls onto a rotatable filter screen 3 located below the feed inlet 2 inside the filter box 4. The filter screen 3, thanks to the properties of its high-quality material, effectively intercepts impurities and large particles in the raw material. Simultaneously, a cam 5, which is in contact with the lower part of the filter screen 3, begins to rotate under the drive of a motor 7. The protruding end of the cam 5 causes the filter screen 3 to vibrate regularly, thereby enhancing the filtration effect and preventing clogging.

[0023] The filtered material enters the centrifuge drum 10, which is fixedly mounted on the second gear 9, through the discharge port 27 on the drum cover 12 and connected to the filter box 4. At this time, one end of the connecting shaft 6 drives the first gear 8 to rotate through the transmission mechanism. The first gear 8 and the second gear 9 mesh with each other, thereby driving the centrifuge drum 10 to rotate at high speed. The centrifuge drum 10 is made of a special material that can withstand the centrifugal force generated by high-speed rotation. Several evenly distributed and reasonably sized filter holes 11 on it allow the insect protein solution to be filtered out quickly.

[0024] During the rotation of the centrifuge tank 10, the cleaning brush 13 mounted on the tank lid 12 begins to function. On one hand, the soft and elastic cleaning brush 13 fits tightly against the inner wall of the filter box 4, cleaning the inner wall of the filter box 4 during rotation to prevent impurities from remaining; on the other hand, when the cleaning brush 13 rotates to contact the filter screen 3, it squeezes the material remaining on the filter screen 3, causing the residual insect protein solution in the material to be further squeezed out, thereby improving the protein extraction rate.

[0025] In one embodiment, the filter screen 3 is designed with an inclined orientation, which facilitates the automatic downward discharge of filtered impurities under gravity. The connecting shaft 6 is rotatably mounted inside the filter box 4, ensuring stable rotation and reducing friction and wear. The drive motor 7 is fixedly mounted on the operating box 1, providing a stable mounting position. The filter box 4 is fixedly mounted inside the operating box 1, forming a unified whole and enhancing the stability of the device.

[0026] In one embodiment, the filter screen 3 is inclined in a direction that extends through both the filter screen 3 and the operating box 1, facilitating the smooth discharge of impurities. A discharge port 18 is provided in the inclined direction of the filter screen 3. The discharge port 18 is reasonably designed and appropriately sized to ensure rapid discharge of impurities. The discharge port 18 is located on both the operating box 1 and the filter box 4, enabling communication between the two. A collection box 14 is located below the discharge port 18. The collection box 14 has a suitable capacity to collect the filtered impurities. The collection box 14 is fixedly installed on the operating box 1 to prevent movement during device operation.

[0027] In one embodiment, the transmission mechanism includes a worm gear 15 fixedly mounted on a connecting shaft 6. The worm gear 15 has high precision and high transmission efficiency. The worm gear 15 meshes with a worm wheel 16, and the worm wheel 16 cooperates with the worm gear 15 to achieve power reduction and steering. The worm wheel 16 is fixedly mounted on a rotating shaft 17, which provides support for the rotation of the worm wheel 16. The rotating shaft 17 is fixedly mounted on a first gear 8, transmitting the rotation of the worm wheel 16 to the first gear 8. The first gear 8 is rotatably mounted on a connecting plate 19, which provides a stable mounting base for the first gear 8. The connecting plate 19 is fixedly mounted inside the operating box 1, enhancing its stability.

[0028] The working principle of the low-temperature extraction device for insect protein proposed in this invention is as follows: During operation, the insect raw material is fed into the device through the feed inlet 2, which is fixedly connected to the top of the operating box 1. The raw material falls onto the filter screen 3, which is designed to be inclined and rotated inside the filter box 4, below the feed inlet 2. The inclined filter screen 3 facilitates the automatic sliding of impurities after filtration under the action of gravity. The impurities follow the inclined direction of the filter screen 3 and are quickly discharged into the collection box 14, which is fixedly installed on the operating box 1 and has a suitable capacity, through the discharge port 18, which is opened on the operating box 1 and the filter box 4 and has a reasonable size to connect the two.

[0029] During the filtration process of the filter screen 3, the drive motor 7, fixedly mounted on the control box 1, starts, driving the connecting shaft 6, which is fixedly connected to its output end, to rotate stably within the filter box 4, reducing friction and wear. When the connecting shaft 6 rotates, on the one hand, its protruding end contacts the bottom of the filter screen 3, causing the filter screen 3 to vibrate regularly, enhancing the filtration effect and preventing clogging; on the other hand, the high-precision and high-efficiency worm gear 15, fixedly mounted on the connecting shaft 6, rotates accordingly, engaging with the worm wheel 16 to achieve power deceleration and steering. The worm wheel 16 is fixedly mounted on the rotating shaft 17, which transmits power to the first gear 8 fixed thereon. The first gear 8 is rotatably mounted on the connecting plate 19, which provides a stable mounting base for it. The connecting plate 19 is fixedly mounted inside the control box 1 to enhance stability.

[0030] The first gear 8 meshes with the second gear 9, driving the centrifuge drum 10, which is fixedly mounted on the second gear 9, to rotate. The centrifuge drum 10 is made of a special material that can withstand the centrifugal force generated by high-speed rotation. Several evenly distributed and reasonably sized filter holes 11 are opened on it, allowing the insect protein solution in the filtered material to be filtered out quickly. During the rotation of the centrifuge drum 10, a soft and elastic cleaning brush 13 mounted on the drum lid 12 rotates to clean the inner wall of the filter box 4 to prevent impurities from remaining. At the same time, it squeezes the residual material on the filter screen 3, causing the residual insect protein solution to be further squeezed out, thereby improving the protein extraction rate.

[0031] In one embodiment, the second gear 9 is rotatably mounted on the connecting plate 19 to ensure stable rotation. The second gear 9 meshes with a third gear 20, which cooperates with the second gear 9 to further transmit and convert power. The third gear 20 is rotatably mounted on the connecting plate 19, providing rotational support for the third gear 20. A reciprocating threaded rod 21 is fixedly mounted on the third gear 20; the reciprocating threaded rod 21 has a unique design enabling reciprocating motion.

[0032] In one embodiment, the reciprocating threaded rod 21 is threadedly connected to a cleaning scraper 22. The cleaning scraper 22 cooperates with the reciprocating threaded rod 21 and reciprocates under the drive of the reciprocating threaded rod 21. The cleaning scraper 22 is slidably connected inside the operating box 1 to ensure stable sliding. The cleaning scraper 22 is in contact with the inner wall of the operating box 1, and can clean the inner wall of the operating box 1 during the reciprocating motion to prevent insect protein residue.

[0033] In one embodiment, the operating box 1 has a discharge port 23 at its bottom. The discharge port 23 is reasonably designed to facilitate the smooth discharge of extracted insect protein. Support legs 24 are fixedly installed at the bottom of the operating box 1. The support legs 24 are strong and can stably support the entire device. Four support legs 24 are provided, evenly distributed at the bottom of the operating box 1, enhancing the stability of the device.

[0034] In one embodiment, the control box 1 is equipped with a rotatable door 25, which is easy to open and facilitates inspection and maintenance of the device's interior. A control panel 26 is fixedly installed in the control box 1. The control panel 26 is easy to operate and allows for precise control of various functions of the device. A temperature control component is installed inside the control box 1. This component has high precision and can accurately control the temperature inside the control box 1, meeting the requirements for low-temperature extraction of insect proteins.

[0035] The working principle of the low-temperature extraction device for insect protein proposed in this invention is as follows: During operation, insect raw materials are fed into the device through the feed inlet 2, which is fixedly connected to the top of the operating box 1. The raw materials fall onto the filter screen 3, which is designed to be inclined and rotated inside the filter box 4, below the feed inlet 2. The inclined filter screen 3 facilitates the automatic sliding of impurities after filtration under the action of gravity, and discharges them through the discharge outlet 18 opened on the operating box 1 and the filter box 4 into the collection box 14 fixedly installed on the operating box 1.

[0036] During the filtration process of the filter screen 3, the drive motor 7, fixedly installed on the control box 1, starts, driving the connecting shaft 6, which is fixedly connected to its output end, to rotate stably inside the filter box 4. When the connecting shaft 6 rotates, on the one hand, its protruding end contacts the bottom of the filter screen 3, causing the filter screen 3 to vibrate regularly, enhancing the filtration effect and preventing clogging; on the other hand, the worm gear 15, fixedly installed on the connecting shaft 6, rotates, and the worm wheel 16 meshing with the worm gear 15 cooperates to achieve power deceleration and steering. The worm wheel 16 transmits power to the first gear 8 fixed on it through the rotating shaft 17. The first gear 8 is rotatably installed on the connecting plate 19 fixed inside the control box 1.

[0037] The first gear 8 meshes with the second gear 9, which is also rotatably mounted on the connecting plate 19. The second gear 9 further transmits power to the third gear 20, which meshes with it and is also rotatably mounted on the connecting plate 19. The third gear 20 drives the reciprocating threaded rod 21 fixed thereon to rotate. The reciprocating threaded rod 21 achieves reciprocating motion due to its unique design. The cleaning scraper 22, which is threadedly connected to the reciprocating threaded rod 21, reciprocates along the interior of the slidingly connected operating box 1 under the drive of the reciprocating threaded rod 21. The cleaning scraper 22 is in contact with the inner wall of the operating box 1, which can clean the inner wall of the operating box 1 and prevent insect protein residue.

[0038] The second gear 9 also drives the centrifuge barrel 10 fixed thereon to rotate. The centrifuge barrel 10 is made of a special material that can withstand the centrifugal force generated by high-speed rotation. Several evenly distributed and reasonably sized filter holes 11 are opened on it, which allows the insect protein solution in the filtered material to be filtered out quickly. During the rotation of the centrifuge barrel 10, the cleaning brush 13 installed on the barrel cover 12 rotates to clean the inner wall of the filter box 4 to prevent impurities from remaining. At the same time, it squeezes the residual material on the filter screen 3, which further squeezes out the residual insect protein solution and improves the protein extraction rate.

[0039] The extracted insect protein is discharged through the well-designed discharge port 23 at the bottom of the operating chamber 1. During operation, four high-strength support legs 24, evenly distributed at the bottom of the operating chamber 1, stably support the entire device. The internal components of the device can be inspected and maintained by rotating the easily accessible door 25 mounted on the operating chamber 1. The user-friendly control panel 26, fixed to the operating chamber 1, allows for precise control of all functions. Furthermore, the high-precision temperature control components inside the operating chamber 1 accurately control the temperature, meeting the requirements for low-temperature extraction of insect protein.
