Description

Technical Field

[0001] This utility model relates to the field of cottonseed protein production technology, specifically to a complete set of equipment for continuous production of cottonseed dephenolized protein. Background Technology

[0002] Cottonseed protein is an important plant protein resource with broad application prospects in feed, food and other fields due to its high protein content and good nutritional value. However, cottonseed kernels contain toxic free gossypol and other phenolic substances, which limits its direct application in food and monogastric animal feed. Therefore, efficient and thorough removal of phenolic substances (especially gossypol) from cottonseed kernels is a key step in producing safe and high-quality cottonseed dephenolized protein.

[0003] Existing desiccant protein production often faces the following problems: First, the dephenolization efficiency is insufficient. Traditional processes often have poor pretreatment effects on cotton kernels, such as insufficient crushing and insufficient softening time. This affects the penetration of the dephenolization solution into the cotton kernels, impacting the leaching efficiency and thoroughness of phenolic substances. This not only reduces the yield of the final protein product but may also leave harmful substances, affecting the safety and cleanliness of the product. Second, the crushing of cotton kernels often generates a lot of dust during the production process. If not controlled, this dust will diffuse into the surrounding area and subsequent processes, affecting the working environment and potentially mixing into subsequent softening, pressing, or leaching stages, interfering with the process and reducing product quality. Therefore, a device is needed to solve these problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a complete set of equipment for continuous production of cottonseed dephenolized protein, which solves the problems of insufficient dephenolization efficiency and the possibility of dust mixing into subsequent processes during the dephenolization process of cotton kernels.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a complete set of equipment for continuous production of cottonseed dephenolized protein, comprising a wind-powered seed cleaner, a toothed roller crusher, a stepped screen, a softening pot, a pressing machine, a flat plate dryer, a dephenolized extractor, and a disc dryer connected in sequence. The toothed roller crusher includes a cabinet with a crushing chamber inside. The top and one side of the cabinet are respectively provided with a feed pipe and a discharge pipe. One end of the feed pipe is connected to the output end of the wind-powered seed cleaner, and the discharge pipe is connected to the input end of the stepped screen.

[0006] The crushing chamber is equipped with a rotating drum screen. A first drive motor is fixedly connected to one side of the cabinet. The output end of the first drive motor is fixedly connected to one side of the drum screen to drive the drum screen to rotate. A scraping mechanism is provided on the inner wall of the crushing chamber at the bottom of the drum screen to scrape off the adhering substances on the surface of the drum screen. An exhaust pipe is provided at the bottom of the crushing chamber to remove dust from the crushing chamber. A crushing mechanism is provided inside the crushing chamber to crush cottonseed.

[0007] Optionally, the scraping mechanism includes a mounting plate, a replacement plate, and a scraping brush. The mounting plate is located on the inner bottom wall of the crushing chamber. The replacement plate is detachably mounted on the upper surface of the mounting plate. The scraping brush is fixedly connected to the upper surface of the replacement plate and fits against the outer surface of the drum screen.

[0008] Optionally, the bottom of the mounting plate is provided with a clamping mechanism to make the scraping brush on the mounting plate fit more closely with the drum screen.

[0009] Optionally, the clamping mechanism includes a sleeve, a compression spring, and a connecting rod. The sleeve is rotatably connected to the inner wall of the crushing chamber via a rotating shaft. The connecting rod is slidably disposed on the inner wall of the sleeve, and its end away from the sleeve is rotatably connected to the lower surface of the mounting plate. The compression spring is disposed inside the sleeve, and one end of the compression spring contacts one end of the connecting rod to push the connecting rod outward.

[0010] Optionally, the crushing mechanism includes a second drive motor, a crushing roller, and an auxiliary roller. The second drive motor is fixedly connected to one side of the cabinet. The crushing roller and the auxiliary roller are both rotatably arranged inside the cabinet and located below the feed pipe. The output end of the second drive motor is fixedly connected to one end of the crushing roller to drive the crushing roller to rotate.

[0011] Optionally, an adjustment mechanism is provided on one side of the auxiliary roller to adjust the distance between the auxiliary roller and the crushing roller.

[0012] Optionally, the adjustment mechanism includes a mounting frame, an adjusting screw, and a guide groove.

[0013] Optionally, both the crushing roller and the auxiliary roller have convex teeth fixedly connected to their outer surfaces to improve crushing efficiency, and the convex teeth on the surfaces of the crushing roller and the auxiliary roller are arranged alternately.

[0014] This utility model provides a complete set of equipment for continuous production of cottonseed dephenolized protein, which has the following beneficial effects:

[0015] 1. The raw material (cottonseed) can be cleaned by the wind-powered seed cleaner. After the cottonseed is crushed by the toothed roller crusher, it enters the stepped screen to obtain cotton kernels. Then, the cotton kernels can be softened and dried by passing through the softening pot, pressing machine and plate dryer. After processing, the cotton kernels enter the dephenolizing extractor to remove phenol to obtain dephenolized protein. After drying, the protein can be stored. This set of equipment can improve the efficiency of dephenolization (after softening and pressing), so that the phenolic substances in the cotton kernels can be removed more completely and the cleanliness of the product can be improved.

[0016] 2. Through the coordinated arrangement of the drum screen, the first drive motor, the scraping mechanism, and the crushing mechanism, the crushed cotton kernels will enter the drum screen for preliminary screening, reducing the screening pressure of the stepped screen. The first drive motor can drive the drum screen to rotate, improving the screening efficiency. At the same time, the scraping mechanism can scrape the surface of the drum screen to prevent the cotton kernels from clogging the screen and affecting the screening efficiency. Furthermore, the exhaust pipe set at the bottom can remove the dust generated during the crushing process, reducing the impact on subsequent steps. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0024] Please see Figures 1 to 5 This utility model provides a technical solution: a complete set of equipment for continuous production of cottonseed dephenolized protein, including a wind-powered seed cleaner 101, a toothed roller crusher, a stepped screen 102, a softening pot 103, a pressing machine 104, a flat plate dryer 105, a dephenolized extractor 106, and a disc dryer 107 connected in sequence. The toothed roller crusher includes a cabinet 1 with a crushing chamber 2 inside. The top and one side of the cabinet 1 are respectively provided with a feed pipe 3 and a discharge pipe 4. One end of the feed pipe 3 is connected to the output end of the wind-powered seed cleaner 101, and the discharge pipe 4 is connected to the input end of the stepped screen 102.

[0025] The crushing chamber 2 is equipped with a rotating drum screen 5. A first drive motor 13 is fixedly connected to one side of the cabinet 1. The output end of the first drive motor 13 is fixedly connected to one side of the drum screen 5 to drive the drum screen 5 to rotate. A scraping mechanism is provided on the inner wall of the crushing chamber 2 at the bottom of the drum screen 5 to scrape off the adhering substances on the surface of the drum screen 5. An exhaust pipe 6 is provided at the bottom of the crushing chamber 2 to remove the dust in the crushing chamber 2. The crushing chamber 2 is equipped with a crushing mechanism inside to crush cottonseed.

[0026] After cottonseeds enter the wind-powered seed cleaner 101, the wind-powered seed cleaner 101 can screen out impurities such as branches and leaves, improving the cleanliness of the cottonseeds. The screened cottonseeds enter the toothed roller crusher to crush the outer shell and obtain cotton kernels. After crushing, they enter the drum screen 5 in the cabinet 1 for initial screening, discharging excessively fine particles such as dust. At the same time, the internal exhaust pipe 6 removes the dust generated during the crushing process, reducing the impact on subsequent steps. The scraping mechanism can scrape the drum screen 5 to reduce the clogging of the screen surface caused by dust or other impurities. The crushed cotton kernels enter the stepped screen 102 for further screening, removing excessively large and small impurities and improving the purity of the cotton kernels. After screening, the cotton kernels are put into the softening pot 103. After softening, they enter the pressing machine 104 to flatten and press the cotton kernels. The cottonseed is cracked and then dried in a flat plate dryer 105. After drying, the cottonseed is dried and then put into a dephenolizing extractor 106. Hexane (solvent ratio: 1.1~1.2:1) is added to the dephenolizing extractor 106 to remove oil from the material, and methanol (solvent ratio: 1~0.8:1, concentration: 85~95%) is added to remove gossypol from the material. After passing through the dephenolizing extractor 106, dephenolized protein is obtained. The protein is then dried to obtain the finished product. The first drive motor 13 drives the drum screen 5 to rotate, which is more efficient and faster in separating impurities. The above-mentioned wind-powered seed cleaner 101, stepped screen 102, softening pot 103, pressing machine 104, flat plate dryer 105, dephenolizing extractor 106 and disc dryer 107 are all commonly used devices in the prior art and are well known to those skilled in the art. They will not be described in detail here.

[0027] In this embodiment, as a preferred solution, the scraping mechanism includes a mounting plate 7, a replacement plate 8, and a scraping brush 9. The mounting plate 7 is located on the inner bottom wall of the crushing chamber 2. The replacement plate 8 is detachably mounted on the upper surface of the mounting plate 7. The scraping brush 9 is fixedly connected to the upper surface of the replacement plate 8 and fits against the outer surface of the drum screen 5. The bottom of the mounting plate 7 is provided with a clamping mechanism to make the scraping brush 9 on the mounting plate 7 fit more tightly against the drum screen 5. The clamping mechanism includes a sleeve 10, a compression spring 11, and a connecting rod 12. The sleeve 10 is rotatably connected to the inner wall of the crushing chamber 2 via a rotating shaft. The connecting rod 12 is slidably mounted on the inner wall of the sleeve 10, and one end away from the sleeve 10 is rotatably connected to the lower surface of the mounting plate 7. The compression spring 11 is located inside the sleeve 10, and one end of the compression spring 11 contacts one end of the connecting rod 12 to push the connecting rod 12 outward.

[0028] A compression spring 11 is installed inside the sleeve 10. The compression spring 11 can push the connecting rod 12 inside the sleeve 10 to move outward, thereby pushing the mounting plate 7 connected to one end of the connecting rod 12 to move upward. This further causes the replacement plate 8 and scraping brush 9 installed on the mounting plate 7 to move upward and adhere to the outer surface of the drum screen 5, so that the scraping brush 9 can roll and brush the surface of the drum screen 5. When the particle size clogs the screen of the drum screen 5, the scraping brush 9 can clean the impurities to reduce the clogging of the drum screen 5. At the same time, the spring can continuously push the scraping brush 9 to make the scraping brush 9 contact the drum screen 5 more tightly to ensure scraping efficiency. The replacement plate 8 is fixedly connected to the mounting plate 7 by fixing bolts. The side of the cabinet 1 is provided with an inspection cover plate aligned with the mounting plate 7. After a long period of use, the inspection cover plate can be opened, and the fixing bolts on the mounting plate 7 can be unscrewed to replace the replacement plate 8 to maintain the scraping efficiency of the scraping brush 9.

[0029] In this embodiment, as a preferred option, the crushing mechanism includes a second drive motor 14, a crushing roller 15, and an auxiliary roller 16. The second drive motor 14 is fixedly connected to one side of the cabinet 1. The crushing roller 15 and the auxiliary roller 16 are both rotatably disposed inside the cabinet 1 and located below the feed pipe 3. The output end of the second drive motor 14 is fixedly connected to one end of the crushing roller 15 to drive the crushing roller 15 to rotate. An adjustment mechanism is provided on one side of the auxiliary roller 16 to adjust the distance between the auxiliary roller 16 and the crushing roller 15. The adjustment mechanism includes a mounting bracket 1. 7. Adjusting screw 18 and guide groove 19. The guide groove 19 is opened inside the cabinet 1 along the line connecting the auxiliary roller 16 and the crushing roller 15. The mounting frame 17 is slidably connected to the inner wall of the guide groove 19. The adjusting screw 18 is threaded to one side of the cabinet 1 and one end is rotatably connected to the mounting frame 17. The auxiliary roller 16 is rotatably set on the inner wall of the mounting frame 17. The outer surfaces of the crushing roller 15 and the auxiliary roller 16 are both fixedly connected with protruding teeth 20 to improve crushing efficiency. The protruding teeth 20 on the surfaces of the crushing roller 15 and the auxiliary roller 16 are arranged alternately.

[0030] Material entering through feed pipe 3 falls between crushing roller 15 and auxiliary roller 16. Second drive motor 14 drives crushing roller 15 to rotate. During the rotation of crushing roller 15, crushing roller 15 drives auxiliary roller 16 on one side to rotate. The two work together to crush the material. After crushing, the material enters the drum screen 5 and passes through the screen to enter the next step. The protruding teeth 20 on the surface of crushing roller 15 and auxiliary roller 16 can improve crushing efficiency. By rotating the external adjusting screw 18, the mounting frame 17 inside the cabinet 1 can be moved to adjust the distance between auxiliary roller 16 and crushing roller 15. After the protruding teeth 20 wear, the distance between the two can be adjusted to be closer to maintain crushing efficiency. During the movement of mounting frame 17, external guide groove 19 limits the movement direction of mounting frame 17 to improve the stability of mounting frame 17 during movement.

[0031] In this invention, the working steps of the device are as follows:

[0032] 1. Before use, connect the equipment for multiple steps, then put the cottonseed into the wind-powered seed cleaner 101 for processing. After multiple processing steps, dry the cottonseed to obtain dephenolized protein.

[0033] 2. If the crushing efficiency decreases after a period of use, the external adjusting screw 18 can be adjusted to bring the distance between the crushing roller 15 and the auxiliary wheel closer. The inspection cover should be opened regularly to check the length of the scraping brush 9. If the length is too short to contact the drum screen 5, the replacement plate 8 should be replaced. After replacement, it can continue to be used.

Specific examples have been used to illustrate the principles and implementation methods of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this utility model.
