[0002] Pumpkin protein comes from mature pumpkin seeds, which are also called pumpkin kernels, white pumpkin seeds, golden pumpkin seeds, etc. Pumpkin seeds are rich in nutrients, containing about 50% fat and 30% to 40% protein. After defatting, the pumpkin protein content can reach more than 60%, and its protein is rich in amino acid composition, making it a good source of plant protein.

[0003] Currently, subcritical low-temperature extraction technology is commonly used to extract and prepare pumpkin protein, and the extraction tank is one of the main equipment used in this technology. However, in actual use, after each extraction, a large amount of material will often stick to the inner wall of the extraction tank, which cannot be quickly cleaned. This has a significant negative impact on subsequent extraction processes and needs to be improved. Utility Model Content

[0004] In view of this, the purpose of the present invention is to provide a subcritical extraction tank for extracting pumpkin protein, which can avoid the material from directly adhering to the inner wall of the extraction tank through a liner that can be quickly disassembled and replaced, so as to solve the above problems.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a subcritical extraction tank for extracting pumpkin protein, comprising a tank body, the top of the tank body is open, first hydraulic cylinders are vertically fixed on the left and right outer walls, the bottom is closed and connected to a discharge pipe with a discharge valve, the piston rods of the two first hydraulic cylinders are both upward and fixedly connected to the same tank cover, the tank cover can be coaxially abutted on the top of the tank body and four groups of electric push rods are evenly distributed at circumferential intervals on the top edge of the tank cover, each group of electric push rods is horizontally arranged and its telescopic ends are all facing the center of the tank cover and fixedly connected to a fixed plate, and a plurality of fixed rods distributed in a rectangular array are fixed on the side of the fixed plate away from the corresponding electric push rod. The fixing plate is provided with a positioning groove on the tank cover on the side away from the corresponding electric push rod, and a bushing is installed at the bottom of the tank cover. The top and bottom parts of the bushing are open and four groups of mounting plates are evenly distributed at circumferential intervals on the top end. A number of fixing through holes are provided on the mounting plate, and the top end of the bushing abuts on the bottom of the tank cover. The mounting plate corresponds to the positioning through groove one by one and is inserted through the mounting plate. The fixing plate abuts on the corresponding mounting plate and the fixing rods thereon correspond to the corresponding fixing through holes one by one and are inserted through the fixing plate. The bottom end of the bushing can abut on the inner bottom of the tank body, and the outer wall can abut on the inner wall of the tank body. A feed pipe with a feed valve is connected to the tank cover corresponding to the inner side of the bushing.

[0006] Preferably, the outer diameter of the bushing is adapted to the inner diameter of the tank body.

[0007] Preferably, the mounting plate is matched with the corresponding positioning slot, and the fixing rod is matched with the corresponding fixing hole.

[0008] Preferably, a second hydraulic cylinder is coaxially and fixedly provided at the center of the tank cover, the piston rod of the second hydraulic cylinder is downwardly facing and fixedly connected to an inverted L-shaped support rod, the bottom ends of the two vertical parts of the support rod are fixedly connected to supports, and turntables are rotatably connected to the opposite ends of the two supports, one turntable is coaxially and fixedly connected to the output shaft of the motor built into the corresponding support, the centers of the two turntables are fixedly connected by a straight-line stirring shaft, and the sides of the two turntables are fixedly connected by a number of U-shaped stirring shafts uniformly spaced at circumferential intervals, and a number of stirring balls uniformly spaced at intervals are fixedly sleeved on the straight-line stirring shaft and the U-shaped stirring shaft, and a number of stirring forks are uniformly distributed on the surface of the stirring balls.

During the extraction operation, the feed valve is first opened, and materials such as raw materials and extractants are input into the tank body through the feed pipe. After the feeding is completed, the feed valve is closed and the extraction process can be carried out. During the process, due to the enclosure protection of the bushing, the materials will only stick to the inner wall of the bushing and remain. After the extraction is completed, the discharge valve is opened and the materials can be discharged through the discharge pipe. After the discharge is completed, the first hydraulic cylinder is first operated to extend its piston rod, which can drive the tank cover to move up as a whole until the bushing is moved out of the tank body.

Next, take out a new bushing, first align the mounting plate on it with the positioning slot and insert it into place, then operate the electric push rod to extend its telescopic end, drive the fixed plate to move toward the mounting plate, until the fixed plate is pressed against the corresponding mounting plate, and the fixing rod is inserted into the corresponding fixing hole, press the mounting plate and insert it to fix it, and the new bushing can be fixed and installed firmly, and the installation will not affect subsequent use. After that, operate the first hydraulic cylinder again to retract its piston rod, drive the tank cover down until it is pressed against the top of the tank body again, and re-attach the bushing to the inner wall of the tank body, and then continue the extraction process. In this way, the material can be prevented from directly adhering to the inner wall of the extraction tank by using a bushing that can be quickly and flexibly disassembled and replaced. There is no need to spend a lot of time cleaning the inner wall of the tank before and after extraction. It is only necessary to easily replace the bushing. The overall use is more flexible and convenient, and the overall efficiency and quality of the extraction process can be guaranteed. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] The present invention is described in further detail below with reference to the accompanying drawings and specific embodiments:

[0020] like Figures 1 to 7As shown, a subcritical extraction tank for extracting pumpkin protein comprises a tank body 1 with an open top, first hydraulic cylinders 2 vertically fixed to the left and right outer walls, and a closed bottom connected to a discharge pipe 4 with a discharge valve 3. The piston rods of the two first hydraulic cylinders 2 face upward and are fixedly connected to a common tank lid 5. The tank lid 5 can be coaxially abutted against the top of the tank body 1. Four sets of electric push rods 6 are evenly spaced circumferentially at the top edge of the tank lid 5. Each set of electric push rods 6 is horizontally arranged with its telescopic end facing the center of the tank lid 5 and fixedly connected to a fixing plate 7. A plurality of fixing rods 8 arranged in a rectangular array are fixed to the side of the fixing plate 7 away from the corresponding electric push rod 6. A positioning slot 9 is defined in the tank lid 5 on the side of the fixing plate 7 away from the corresponding electric push rod 6. A bushing 10 is mounted on the bottom of the tank lid 5. Both the top and bottom ends of the bushing 10 are open, and four sets of mounting plates 11 are evenly spaced circumferentially at the top end. The mounting plates 11 are provided with a plurality of fixing holes 12. The top end of the bushing 10 abuts the bottom of the tank cover 5. The mounting plate 11 corresponds to and is inserted through the positioning slots 9. The fixing plate 7 abuts the corresponding mounting plate 11, and the fixing rods 8 thereon correspond to and are inserted through the corresponding fixing holes 12. The bottom end of the bushing 10 can abut the inner bottom of the tank body 1, and the outer wall can abut the inner wall of the tank body 1. The tank cover 5 on the inner side of the bushing 10 is connected to a feed pipe 14 with a feed valve 13.

[0021] In the initial state, the tank cover 5 is pressed against the top of the tank body 1 to form a sealed extraction tank, and the sleeve 10 is pressed against the inner wall of the tank body 1 to form a shielding protection for the inner wall of the tank body 1. During the extraction operation, first open the feed valve 13, and input materials such as raw materials and extractants into the tank body 1 through the feed pipe 14. After the feeding is completed, close the feed valve and carry out the extraction process. During the process, due to the enclosure protection of the sleeve 10, the material will only stick to the inner wall of the sleeve 10 and remain. After the extraction is completed, open the discharge valve 3 and discharge the material through the discharge pipe 4. After the discharge is completed, first operate the first hydraulic cylinder 2 to extend its piston rod, which can drive the tank cover 5 to move up as a whole until the sleeve 10 is moved out of the tank body 1. Then, the four sets of electric push rods 6 are operated to retract their telescopic ends, driving the fixed plate 7 to retract until the fixing rod 8 is pulled out of the corresponding fixing hole 12, thereby releasing the plug-in fixation of the mounting plate 11. The mounting plate 11 is then pulled out and the bushing 10 with the remaining material can be removed. Next, a new bushing 10 is taken and the mounting plate 11 on it is first aligned with the positioning groove 9 and inserted into place. The electric push rods 6 are then operated to extend their telescopic ends, driving the fixed plate 7 to move toward the mounting plate 11 until the fixing plate 7 presses against the corresponding mounting plate 11 and the fixing rod 8 penetrates and inserts into the corresponding fixing hole 12. The mounting plate 11 is pressed and inserted into the fixing hole 12, thus completing the fixed installation of the new bushing 10. The installation is stable and does not affect subsequent use. Afterwards, the first hydraulic cylinder 2 is operated again to retract its piston rod, driving the tank cover 5 to move downward until it presses against the top of the tank body 1 again, reattaching the bushing 10 to the inner wall of the tank body 1, and the extraction process can continue. In this way, the material can be prevented from directly adhering to the inner wall of the extraction tank by using the bushing 10 that can be quickly and flexibly disassembled and replaced. There is no need to spend a lot of time cleaning the inner wall of the tank body 1 before and after extraction. It is only necessary to conveniently replace the bushing 10. The overall use is more flexible and convenient, and can better ensure the overall efficiency and quality of the extraction process.

[0022] In this embodiment, the outer diameter of the sleeve 10 is adapted to the inner diameter of the tank body 1 to ensure that the sleeve 10 can smoothly abut against the inner wall of the tank body 1, forming protection for the inner wall of the tank body 1, preventing the material from sticking and remaining on the inner wall of the tank body 1, and better ensuring the quality of subsequent extraction operations.

[0023] In this embodiment, the mounting plate 11 is matched with the corresponding positioning slot 9 , and the fixing rod 8 is matched with the corresponding fixing hole 12 , so as to ensure smooth fixed installation of the bushing 10 .

[0024] In this embodiment, a second hydraulic cylinder 15 is coaxially mounted and fixedly extends through the center of the tank lid 5. The piston rod of the second hydraulic cylinder 15 faces downward and is fixedly connected to an inverted L-shaped support rod 16. The bottom ends of the two vertical portions of the support rod 16 are fixedly connected to a support 17. A turntable 18 is rotatably connected to the opposite ends of each support 17. One turntable 18 is coaxially and fixedly connected to the output shaft of a motor 19 built into the corresponding support 17. The centers of the two turntables 18 are fixedly connected by a straight-line stirring shaft 20. The sides of the two turntables 18 are fixedly connected by a plurality of U-shaped stirring shafts 21 evenly spaced around the circumference. A plurality of evenly spaced stirring balls 22 are fixedly mounted on each of the straight-line stirring shafts 20 and the U-shaped stirring shafts 21. The surfaces of the stirring balls 22 are evenly distributed with stirring prongs 23. During the actual extraction process, the extension and retraction of the piston rod of the second hydraulic cylinder 15 can drive the support rod 16 and the stirring mechanism thereon to reciprocate upward and downward as a whole. At the same time, in the stirring mechanism, the motor 19 can drive the two turntables 18 and the straight stirring shaft 20 and U-shaped stirring shaft 21 therebetween to rotate as a whole. Through the mutual cooperation of the multiple stirring balls 22 with stirring forks 23 on the straight stirring shaft 20 and the U-shaped stirring shaft 21, efficient and high-quality comprehensive stirring and mixing of the corresponding materials can be achieved, the stirring effect is better, the stirring efficiency and quality are higher, the extraction efficiency and quality can be effectively improved, and it is more practical.

[0025] In this embodiment, the tank cover 5 on the inner side of the sleeve 10 is connected to an exhaust pipe 24, and the exhaust pipe 24 is provided with an exhaust valve 25. After the feeding is completed, it can be used in conjunction with existing conventional exhaust equipment to exhaust the interior of the tank body 1 to ensure the low-pressure environment used for subcritical extraction.

[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
