Description
Technical Field
[0001] The present invention relates to the technical field of removing cyclopropene fatty acids from cottonseed protein, and specifically to a device for removing cyclopropene fatty acids from cottonseed protein. Background Art
[0002] With the increasing global demand for protein resources, cottonseed protein, as an important source of plant protein, is increasingly widely used in many fields such as feed and food. However, the naturally occurring cyclopropene fatty acids (CPFA) in cottonseed protein have become the key factors restricting the improvement of its quality and wide application.
[0003] Traditional methods for removing cyclopropene fatty acids mainly rely on simple chemical reagent treatment or single heating methods. Although chemical reagent treatment can decompose CPFA to a certain extent, it often introduces new chemical impurities, which not only affect the purity of cottonseed protein but also may pose food safety hazards, making the subsequent purification process cumbersome and complex. For the simple heating method, due to the lack of effective means for material agitation and temperature uniformity control, the heating is often uneven. The material near the heat source is overheated and denatured, while the CPFA far from the heat source is not completely removed, resulting in low removal efficiency and unstable effects.
[0004] In addition, most of the existing removal equipment has a simple structure, mostly static reaction kettles or containers with only simple stirring functions, which cannot meet the requirements of large-scale and continuous production. The material feeding process is rough, and it is difficult to ensure that the amount of material input each time and the heating conditions are the same, resulting in uneven quality of the final products. At the same time, during the operation of the equipment, heat loss is serious, which not only wastes energy but also makes it difficult to maintain a stable removal process environment, further reducing production efficiency and product quality.
[0005] In summary, there is an urgent need for an innovative, efficient and stable device for removing cyclopropene fatty acids from cottonseed protein to overcome the many defects of the existing technology, meet the growing market demand, and promote the high-quality development of the cottonseed protein industry.

[0017] Beneficial effects
[0018] The present invention provides a device for removing cyclopropene fatty acids in cottonseed protein. It has the following beneficial effects: The device for removing cyclopropene fatty acids in cottonseed protein realizes an efficient and energy-saving industrial removal device through the collaborative design of multiple components, and has the following beneficial effects:
[0019] 1. Improvement of efficient removal performance: The device for removing cyclopropene fatty acids in cottonseed protein of the present invention realizes large-scale continuous removal operation through the uniquely designed turntable and multiple heating barrels.

[0020] 2. Optimization of the material handling process: Structures such as the mesh plate, limiting ring, annular support seat, and annular pressing plate ingeniously arranged inside the heating barrel effectively solve problems such as material accumulation and uneven heating during the heating process.

[0021] 3. Enhancement of the device sealing performance and stability: The partition plate closely fits the top of the heating barrel, effectively blocking heat dissipation, and still maintaining good sealing performance during the rotation of the turntable, ensuring the stable and reliable high-temperature and high-pressure environment required for the removal process. The rotating seat, on the one hand, provides stable power for the turntable to make it rotate smoothly. On the other hand, through cooperation with the support wheels on the base, it significantly reduces the friction loss, extends the service life of the device, reduces the daily maintenance cost, and ensures long-term and high-efficiency production operation.
[0022] 4. Convenient operation and flexible production: The overall structure design of the device fully considers the convenience of operation. For example, the bottom of the inner wall of the heating barrel is inclined and connected to the drain valve. After steaming, the waste liquid can be quickly and completely discharged, facilitating cleaning and preparation for the next batch of production. At the same time, the layout of multiple heating barrels can be flexibly adjusted according to actual production needs. Whether it is small-batch customized production or large-scale industrial production, this device can easily adapt, demonstrating excellent flexibility and adaptability, providing strong support for enterprise production operations.

Specific implementation mode
[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
[0035] Through those skilled in the art, all electrical components in this case are connected to their adapted power sources through wires, and appropriate controllers and encoders should be selected according to the actual situation to meet the control requirements. For the specific connection and control sequence, reference should be made to the working principle below, and the electrical connection should be completed according to the sequence of work among the electrical components. The detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process, and no further description of electrical control will be made.
[0036] Most of the existing removal devices have simple structures, mostly static reaction kettles or containers with only simple stirring functions, which cannot meet the requirements of large-scale and continuous production. The material feeding process is extensive, and it is difficult to ensure that the amount of material input each time and the heating conditions are the same, resulting in uneven quality of the final products. At the same time, during the operation of the device, heat loss is serious, which not only wastes energy but also makes it difficult to maintain a stable removal process environment, further reducing production efficiency and product quality.
[0037] In view of this, the present invention provides a device for removing cyclopropene fatty acids in cottonseed protein. Through the collaborative design of multiple components, an efficient and energy-saving industrial removal device is achieved, ensuring that each portion of raw material can be fully and uniformly cooked, greatly improving the removal efficiency of cyclopropene fatty acids, reducing the incomplete removal phenomenon caused by local overheating or insufficient heating, improving the overall production efficiency, maintaining good sealing performance during the rotation of the turntable, and the layout of multiple heating barrels can be flexibly adjusted according to actual production needs. Whether it is small-batch customized production or large-scale industrial production, this device can be easily adapted, demonstrating excellent flexibility and adaptability, providing strong support for enterprise production operations.
[0038] From Figure 1 , 2 and 3, it can be seen that a device for removing cyclopropene fatty acids in cottonseed protein in this case includes a turntable 1. A plurality of heating barrels 2 are fixedly connected to the top of the turntable 1. The device for removing cyclopropene fatty acids in cottonseed protein further includes a feeding hopper 6, a driving rod 3, a partition plate 4, and a rotating seat 5. The feeding hopper 6 is arranged above one of the heating barrels 2; the driving rod 3 is arranged below the interior of the feeding hopper 6; the partition plate 4 is fixedly connected to the bottom of the outer wall of the feeding hopper 6 and fits against the top of the heating barrel 2; the rotating seat 5 is fixedly connected to the bottom of the turntable 1. Among them, through the driving rod 3, the feeding hopper 6 uniformly disperses materials into a plurality of heating barrels 2 respectively, which is beneficial for comprehensive cooking. The partition plate 4 improves the sealing performance between the heating barrel 2 and the feeding hopper 6 when the heating barrel 2 rotates with the turntable 1, and the rotating seat 5 provides power for the rotation of the turntable 1 and reduces friction.
[0039] In the specific implementation process, it is particularly worth noting that the purpose of the turntable 1 is to orderly place different heating barrels 2 at the bottom of the feeding hopper 6 and seal and connect them under the drive of the rotating seat 5, ensuring seamless docking of the material transportation and heating processes. Inside the heating barrel 2, there are high-precision temperature sensors, efficient heating devices, and pressure sensors to achieve the function of high-temperature and high-pressure cooking. The temperature sensor monitors the temperature inside the barrel in real time and feeds the data back to the control system. The control system precisely regulates the power of the heating device according to the preset temperature curve to ensure that the temperature is always maintained within the most suitable range for the removal of cyclopropene fatty acids, realizing intelligent temperature control and ensuring stable and reliable removal effects. Details of conventional electrical connections, control algorithms, etc. well-known to those skilled in the art are not elaborated here. The heating barrel 2 integrates temperature and pressure sensors and combines with a closed-loop control system to achieve precise temperature control within ±1°C, ensuring the continuous decomposition of cyclopropene fatty acids in the optimal temperature range (usually 160 - 180°C). When the driving rod 3 batches the materials inside the feeding hopper 6 into the heating barrel 2, it not only ensures uniformity but also can guarantee the relative closure of the feeding hopper 6 with its special closed structure design. This closed characteristic effectively prevents a large amount of heat loss inside the heating barrel 2, avoids excessive energy consumption due to frequent heat replenishment, makes the entire removal process more energy-saving and environmentally friendly, and at the same time, the stable thermal environment is conducive to the continuous and efficient progress of the cyclopropene fatty acid removal reaction, improving product quality and production efficiency. The cyclopropene fatty acid removal device for cottonseed protein comprehensively improves the removal efficiency of cyclopropene fatty acids, product quality, and reduces energy consumption and production costs by the coordinated operation and fine design of various components, from aspects such as the uniformity of material feeding, the tightness of the heating process, and the precise control of the turntable rotation.
[0040] In an implementable manner, please refer to Figure 2 、 Figure 4 and Figure 5 ., a wire mesh plate 21 is movably connected inside the heating barrel 2. A limiting ring 22 is fixedly connected to the outer wall of the wire mesh plate 21. A ring-shaped support seat 23 fixedly connected to the inner wall of the heating barrel 2 is arranged at the bottom of the limiting ring 22. A ring-shaped pressing plate 24 movably connected to the inner wall of the heating barrel 2 is arranged at the top of the limiting ring 22.
[0041] In the specific implementation process, it is particularly worth noting that the mesh number of the wire mesh plate 21 is not limited, and it should meet the requirement of supporting the cottonseed protein without leakage and realizing cooking. The settings of the limiting ring 22 and the ring-shaped support seat 23 realize the installation of the wire mesh plate 21 at the middle position inside the heating barrel 2. At the same time, the purpose of setting the ring-shaped pressing plate 24 is to press down the limiting ring 22 to ensure the stable and effective position of the wire mesh plate 21.
[0042] Furthermore, a movably connected ball bearing 241 is embedded in the top of the annular support seat 23 and the bottom of the annular pressure plate 24 , and the outer wall of the ball bearing 241 is rollingly connected to the surface of the limiting ring 22 through an annular reserved groove 242 .
[0043] In the specific implementation process, it is worth pointing out that the purpose of the ball 241 is to reduce the friction between the limit ring 22 and the annular support seat 23 and the annular pressure plate 24, so that under the drive of the driving rod 3, the mesh plate 21 rotates, which is beneficial to the uniform distribution of cottonseed protein and improves the cooking effect.
[0044] In one practicable manner, see Figure 1 , Figure 2 , Figure 4 and Figure 7 A reserved notch 45 is provided at the top of the partition plate 4, a plurality of sliders 243 are fixedly connected to the outer wall of the annular pressure plate 24, the outer wall of the slider 243 is slidably connected to a slide groove 244 provided on the inner wall of the heating barrel 2, a plurality of reserved hanging holes 245 are provided above the inner wall of the annular pressure plate 24, and a plurality of distribution rods 246 are fixedly connected to the inner wall of the annular pressure plate 24 at equal intervals in a circular shape.
[0045] In the specific implementation process, it is worth pointing out that the purpose of the reserved notch 45 is that the rotating seat 5 rotates unidirectionally, and each time a heating barrel 2 is aligned with the upper hopper 6, the previous heating barrel 2 aligned with the upper hopper 6 continues to perform high-temperature cooking under the closure of the partition plate 4, and the heating barrel 2 that first completes the unloading and cooking in the whole process is just located at the position of the reserved notch 45, which is convenient for the staff to remove the annular pressure plate 24 inside it. When removing it, the reserved hanging holes 245 can be hooked by multiple hooks respectively, and the annular pressure plate 24 is lifted up. At this time, the slider 243 moves along the inner wall of the slide groove 244 to Slide up until it is out of the heating barrel 2, and then use a hook to take out the mesh plate 21 placed on the top of the annular support seat 23. Note that the angle of the mesh plate 21 cannot be too tilted to prevent the cottonseed protein on the top from falling off. This part of the cottonseed protein has been effectively removed by high-temperature cooking. When the mesh plate 21 rotates under the drive of the driving rod 3, the annular pressing plate 24 will not rotate due to the influence of the slider 243 and the slide groove 244. Therefore, the spreading rod 246 fixed on the inner wall of the annular pressing plate 24 can help to further evenly spread the material on the top of the mesh plate 21, which is beneficial to the uniformity of the main cooking.
[0046] In one practicable manner, see Figure 3 , Figure 4 , Figure 8 and Figure 10A push rod 31 is provided below the driving rod 3, and a base 32 is fixedly connected to the bottom of the push rod 31. The outer wall of the base 32 is fixedly connected to the inner wall of the mesh plate 21. A reserved notch 33 is opened below the outer wall of the driving rod 3, and a telescopic rod 34 is fixedly connected to the top of the driving rod 3. The outer wall of the driving rod 3 is fixedly connected with a push plate 36 and an umbrella-shaped bulk plate 37 from top to bottom in sequence. A rubber sleeve 38 is provided below the umbrella-shaped bulk plate 37. A conical bucket 39 is threadedly connected to the top of the inner wall of the rubber sleeve 38, and the conical bucket 39 is fixedly connected to the upper part of the inner wall of the upper hopper 6.
[0047] In the specific implementation process, it is worth pointing out that during the lifting process of the driving rod 3, the reserved notch 33 on the outer wall thereof is designed with an inclined surface, and this part fits on the top of the top rod 31, and drives the mesh plate 21 to rotate through the top rod 31 and the base 32, which serves as the power for the rotation of the mesh plate 21, wherein the base 32 is located at the center of the mesh plate 21, and the top rod 31 is located at an eccentric position, which is conducive to the driving of the driving rod 3, and the telescopic rod 34 can choose a telescopic motor, and the specific model is not limited, as long as it meets the use requirements, as the power for the reciprocating lifting of the driving rod 3, the conical bucket The purpose of the push plate 36 is to push the material inside the conical bucket 39 into the vertical tube part at the bottom of the conical bucket 39 by the lifting and lowering of the driving rod 3. In this process, the umbrella-shaped bulk material plate 37 is also located in the vertical tube part at the bottom of the conical bucket 39 to receive the cottonseed protein pushed down by the push plate 36, so that the heat inside the heating barrel 2 connected to the conical bucket 39 will not be lost in large quantities. As the driving rod 3 moves downward, the umbrella-shaped bulk material plate 37 is pushed from the inside of the conical bucket 39 (vertical tube part) ) below, while the push plate 36 is still located inside the conical bucket 39 (vertical tube part), the cottonseed protein falls relatively evenly on the top of the mesh plate 21 due to the angle setting of the umbrella-shaped bulk plate 37, and the centrifugal force generated by the rotation of the mesh plate 21 and the stirring of the distribution rod 246 further improve the uniformity of the dispersion of the cottonseed protein. When the umbrella-shaped bulk plate 37 rises again and enters the conical bucket 39, the cottonseed protein remaining on its surface is cleaned by the scraping of the rubber sleeve 38 and also falls on the top of the mesh plate 21 until the umbrella-shaped bulk plate 37 is completely entered. The material enters the conical bucket 39, and the driving rod 3 continues to rise and enters the next feeding cycle, thus forming a three-dimensional dispersion mechanism. The driving rod 3 drives the linkage design of the umbrella-shaped bulk plate 37 and the mesh plate 21. Through the triple effects of centrifugal force + mechanically driven distribution rod 246 + gravity falling, the material distribution uniformity is improved by more than 40%, and a heat loss prevention structure is formed at the same time. The nested design of the conical bucket 39 and the umbrella-shaped bulk plate 37, combined with the scraping and cleaning of the rubber sleeve 38, achieves a heat loss of less than 5% in the feeding process, which saves 30% energy compared with traditional open feeding.
[0048] In one practicable manner, see Figure 1 , Figure 2 andFigure 6 On the outer wall of the feeding hopper 6, a support ring 42 is fixedly connected. The outer wall of the support ring 42 is fixedly connected to the top of the partition plate 4 through a reinforcing rod 41. On one side of the outer wall of the support ring 42, a bracket 43 is fixedly connected. At the bottom of the bracket 43, a base 44 is fixedly connected. At the top of the bracket 43, a mounting frame 35 is fixedly connected, and the mounting frame 35 is fixedly connected to the top of the telescopic rod 34.
[0049] In the specific implementation process, it is particularly pointed out that the support ring 42, the bracket 43 and the base 44 provide sufficient support for the feeding hopper 6 and fix the telescopic rod 34, improving the connection strength between the partition plate 4 and the feeding hopper 6.
[0050] In an implementable manner, please refer to Figure 1 、 Figure 2 、 Figure 6 、 Figure 9 and Figure 10 . On the bottom of the rotating seat 5, a number of protrusions 51 are provided. The bottom of the protrusion 51 is attached to a support wheel 52. The bottom of the support wheel 52 is installed on the top of the base 44, and a driving motor 53 is installed on the top of the base 44.
[0051] In the specific implementation process, it is particularly pointed out that the purpose of setting the protrusion 51 is that when the rotating seat 5 and the turntable 1 rotate synchronously, once the protrusion 51 is separated from the bottom support wheel 52, the height of the rotating seat 5 and the turntable 1 drops. In this way, the abutting force between the top of the heating barrel 2 and the bottom of the partition plate 4 decreases, and the deformation of the sealing gasket at the bottom of the partition plate 4 caused by the abutting force of the heating barrel 2 is restored to a certain extent, but there is still a relatively sealed fitting effect with the heating barrel 2, which is conducive to their relative rotation. When a certain heating barrel 2 is aligned with the feeding hopper 6, just the protrusion 51 and the support wheel 52 are in contact. In this way, driven by the rotating seat 5, the heating barrel 2 moves upward, which is conducive to abutting against the partition plate 4 and improving the sealing effect. In this way, the combination of sealing and rotation reduces wear. The specific model of the driving motor 53 is not limited, as long as it meets the use requirements;
[0052] It can be understood that such a rotary multi-barrel layout realizes the cyclic operation of the turntable 1 driving multiple heating barrels 2. Through the precise cooperation of the rotating seat 5 and the protrusion 51, the lifting and sealing are realized (the contact control between the protrusion 51 and the support wheel 52), which not only ensures the sealing during heating but also reduces the frictional loss;
[0053] Furthermore, on the top of the driving motor 53, a rotating shaft 531 is fixedly connected. On the outer wall of the rotating shaft 531, a sleeve 532 is sleeved. The top of the sleeve 532 is fixedly connected to the bottom of the turntable 1. On the outer wall of the rotating shaft 531, a number of ridges 533 are provided, which are slidably connected to the inner wall of the sleeve 532.
[0054] In the specific implementation process, it is particularly worth noting that by setting the sleeve 532 and the convex rib 533, the synchronous rotation of the rotating shaft 531 and the sleeve 532 can be ensured, and the lifting height of the rotating seat 5 can be compensated to ensure the effective connection between the driving motor 53 and the turntable 1. Of course, a ball structure can be added to the outer wall of the convex rib 533 to facilitate the reduction of friction.
[0055] In an implementable manner, please refer to Figure 1 and Figure 2 , a pressure relief valve 46 communicating with the partition plate 4 is provided on one side of the heating barrel 2 away from the feeding hopper 6 above.
[0056] In the specific implementation process, it is particularly worth noting that below the partition plate 4 where multiple heating barrels 2 are evenly distributed, that is, the heating barrel 2 about to enter below the reserved notch 45 reduces the internal pressure through the pressure relief of the pressure relief valve 46, avoiding the concentrated jet of high-pressure gas when suddenly moving below the reserved notch 45. Of course, a steam recovery system can be connected to the pressure relief valve 46. By connecting to the steam recovery system, a steam recovery rate of up to 85% can be achieved.
[0057] In an implementable manner, please refer to Figure 2 and Figure 4 , the bottom of the inner wall of the heating barrel 2 is inclined and is connected with a drain valve 25.
[0058] In the specific implementation process, it is particularly worth noting that the purpose of the drain valve 25 is to drain the water inside the heating barrel 2, and after cleaning the inside of the heating barrel 2, it is convenient to drain the sewage after cleaning.
[0059] Specifically, the cyclopropene fatty acid removal device in cottonseed protein realizes an efficient and energy-saving industrial removal device through the collaborative design of multiple components. The test data is as follows:
[0060] Index Parameter / Effect Removal Efficiency Residual Amount of Cyclopropene Fatty Acid ≤ 50 mg / kg (Initial 800 mg / kg) Energy Consumption 30% Lower than the Traditional Process Processing Capacity Single Heating Barrel Processing Quantity 50 kg, 4-Station System Production Capacity 200 kg / h Protein Denaturation Rate ≤ 8% (Traditional Process ≥ 15%) Continuous Operation Period 72-hour Fault-Free Operation (Supported by Automatic Pressure Relief + Waste Heat Recovery)
[0061] Thus, it can be seen that the cyclopropene fatty acid removal device in cottonseed protein is particularly suitable for a production line with an annual output of ten thousand tons of cottonseed protein. The 316L stainless steel components certified by the FDA can meet the food-grade production requirements. The measured data shows that the residual amount of cyclopropene fatty acid can be reduced from the initial 800 mg / kg to less than 50 mg / kg, and the protein denaturation rate is controlled within 8%. The efficiency is three times higher than that of the traditional cooking process. Its modular design is also convenient for expansion and used for the detoxification treatment of other oil crop proteins.
[0062] Working principle:
[0063] First, the operator transports the cottonseed protein raw material to be processed beside the device. After ensuring that all components of the device are in an initial static and normal state, the raw material is poured into the feeding hopper 6. The feeding hopper 6 is effectively supported by the partition plate 4 connected by the support ring 42 and the reinforcing rod 41 supported by the bracket 43 and the base 44. The driving rod 3 starts to operate under the precise control of the telescopic rod 34. The telescopic rod 34 is stably fixed by the mounting frame 35, and its telescopic movement is driven by an external control system according to a preset program or a real-time manual instruction. When the telescopic rod 34 extends or contracts, it drives the driving rod 3 to move up and down to adapt to the requirements of different raw material quantities and feeding rhythms. The pushing plate 36 on the driving rod 3 pushes the cottonseed protein raw material accumulated at the bottom of the feeding hopper 6 downward forcefully as the driving rod 3 moves, causing it to move towards the umbrella-shaped spreading plate 37. The unique umbrella-shaped structure design of the umbrella-shaped spreading plate 37 uses the frictional force between its inclined surface and the material and the gravity of the material itself to evenly disperse the concentrated raw material into multiple thin streams, ensuring that it falls precisely and equally onto the top of the mesh plate 21 in the corresponding heating barrel 2. The ejector rod 31 and the base 32 below the driving rod 3 form a linkage with the mesh plate 21 in the heating barrel 2. During the feeding process, through the triple action of centrifugal force + the mechanical dialing of the spreading rod 246 + gravity feeding, the material is distributed on the top of the mesh plate 21, completing the feeding operation of a single heating barrel 2. The heating barrel 2 that has completed feeding randomly starts to heat up;
[0064] Subsequently, the driving motor 53 located on the base 44 receives a start signal, and the driving motor 53 drives the rotating shaft 531 to rotate. The rotating shaft 531 stably transmits the torque to the sleeve 532 through the matching structure of the convex ribs 533 on the outer wall and the inner wall of the sleeve 532, thereby driving the turntable 1 to start rotating smoothly. The turntable 1 relies on the support and guidance of the rotating seat 5 at the bottom. The rolling cooperation between the protrusion 51 at the bottom of the rotating seat 5 and the support wheel 52 enables the height of the rotating seat 5 and the turntable 1 to decrease once the protrusion 51 and the support wheel 52 at the bottom separate when the rotating seat 5 and the turntable 1 rotate synchronously. In this way, the pressing force between the top of the heating barrel 2 and the bottom of the partition plate 4 decreases, and the deformation of the sealing gasket at the bottom of the partition plate 4 caused by the pressing force of the heating barrel 2 is partially restored, but there is still a relatively sealed fitting effect with the heating barrel 2, which is conducive to their relative rotation. When a certain heating barrel 2 aligns with the feeding hopper 6, the protrusion 51 and the support wheel 52 just fit together. In this way, under the drive of the rotating seat 5, the heating barrel 2 moves upward, which is conducive to pressing against the partition plate 4 and improving the sealing effect. By combining sealing and rotation in this way, wear is reduced. At this time, the heating barrel 2 that completed feeding in the previous step is sealed by the partition plate 4, and pressure can be increased and heating can be carried out;
[0065] The heating barrels 2 on multiple workstations sequentially perform the above actions to complete feeding and heating, uniformly steam the cottonseed protein on the top of the screen plate 21 until the heating barrel 2 in heating moves to the position below the partition plate 4 where the pressure relief valve 46 is installed. After the pressure relief through the pressure relief valve 46, with the next rotation of the turntable 1, this heating barrel 2 disengages from the partition plate 4 and moves to the reserved notch 45, facilitating the staff to remove the annular pressing plate 24 inside it. When removing, multiple hooks can be used to hook the reserved hanging holes 245 respectively to lift the annular pressing plate 24 upward. At this time, the slider 243 slides upward along the inner wall of the chute 244 until it disengages from the heating barrel 2, and then the screen plate 21 placed on the top of the annular support seat 23 is taken out with a hook. Note that the angle of the screen plate 21 should not be too inclined to prevent the cottonseed protein on the top from falling. This part of the cottonseed protein has undergone high-temperature steaming, achieving effective removal of cyclopropene fatty acids. In this way, the cycle is repeated to achieve continuous and coherent removal operations. After removing the screen plate 21, a new screen plate 21 should be placed inside the heating barrel 2 and fixed by the annular pressing plate 24, which is conducive to the next operation of this heating barrel 2 to the bottom of the feed hopper 6 for feeding. The rotation period of the turntable 1 each time can be determined according to the removal time to ensure that the effective steaming time of a single heating barrel 2 for the cottonseed protein is sufficient;
[0066] After continuously operating for a certain period, the whole equipment can be shut down, and the driving motor 53 can be driven separately to rotate successively to place each heating barrel 2 at the reserved notch 45 respectively, which is conducive to cleaning the inside of the heating barrel 2 and its internal structure. Finally, the drain valve 25 provided at the bottom of the inner wall of the heating barrel 2 is opened. Due to the cooperation of the drain valve 25 with the inclined bottom structure inside the heating barrel 2, the waste liquid quickly and thoroughly drains through the pipeline to the designated collection container under the action of gravity, avoiding the pollution of the waste liquid residue to the subsequent batches of materials.
