Abstract
Description
Technical Field
[0001] This utility model relates to the field of extraction tank technology, specifically a low-temperature extraction tank for sea cucumber polysaccharides. Background Technology
[0002] The low-temperature extraction tank for sea cucumber polysaccharides is a specialized device for extracting polysaccharide components from sea cucumbers. It aims to maximize the preservation of the effective components and nutritional value of sea cucumbers through low-temperature extraction technology. This extraction tank design incorporates modern separation techniques, enabling polysaccharide extraction under low-temperature conditions, reducing the loss of heat-sensitive components while improving extraction efficiency. Sea cucumber polysaccharides have attracted widespread attention due to their various biological activities, such as immunomodulatory, antioxidant, and antitumor properties. Therefore, employing efficient and gentle extraction methods is particularly important.
[0003] Patent CN212633050U discloses a separation device for extracting sea cucumber polysaccharides, including a box body. A mixing chamber is fixedly connected to the top of the inner cavity of the box body. A rotating column is rotatably connected to the top of the inner cavity of the mixing chamber. A fixing block is fixedly connected to the bottom end of the rotating column. Rotating rods are rotatably connected to both sides of the outer surface of the fixing block. Centrifuge racks are fixedly connected to the bottom ends of the two rotating rods. A telescopic rod is fixedly connected to the bottom of the fixing block. A first rotating component is fixedly connected to the bottom end of the telescopic rod. Rotating frames are rotatably connected to both sides of the inner surface of the first rotating component. This invention allows for adjustment of the angle of the centrifuge rack through the cooperation between the rotating column, rotating rods, fixing block, telescopic rod, and rotating frame, thereby adjusting the degree of centrifugation. This increases the degree of centrifugation, preventing excessive polysaccharide components from being extracted incompletely. The operation is also relatively simple.
[0004] Existing sea cucumber polysaccharide extraction technologies primarily rely on centrifuge racks to separate polysaccharide components. While this method can separate polysaccharides from the centrifuge tube, the fixed configuration of the tube limits its effectiveness. Furthermore, the fixed centrifuge tube's inner wall easily traps filter material, preventing complete removal of impurities. The presence of residue negatively impacts subsequent extraction efficiency and purity. To address this issue, we propose a low-temperature sea cucumber polysaccharide extraction tank. By improving the centrifugal extraction structure, we effectively enhance polysaccharide extraction efficiency. Utility Model Content

After starting the motor 900, the motor 900 drives the conductor rotor 910 to rotate, which drives the permanent magnet rotor 720 and the rotating shaft 710 to rotate synchronously through non-contact electromagnetic induction, so that the centrifuge inner tank 700 rotates on the rotating disk 610. During centrifugation, the polysaccharide solution enters the extraction tank 100 through the filter screen 730 on the outer wall and bottom of the centrifuge inner tank 700, while solid impurities are blocked in the centrifuge inner tank 700. At the same time, the low-temperature water input pipe 200 feeds water into the low-temperature tank. Cooling water is input into chamber 101, and the heated cooling water is discharged through hot water outlet pipe 300, forming a circulating cooling system. Temperature sensor 400 monitors the temperature inside extraction tank 100 in real time and feeds the data back to controller 500.
