Description

Technical Field

[0001] This invention relates to the field of component extraction equipment technology, and more specifically to an extraction device for extracting juices in biological experiments. Background Technology

[0002] Polysaccharides and polypeptides are widely found in plants, animals, and microorganisms, possessing various biological activities such as immunomodulation, antitumor activity, and antioxidant activity. They have significant application value in the fields of medicine, health products, and cosmetics. In laboratory and industrial production, extracting polysaccharide and polypeptide combinations from natural raw materials typically requires multiple steps, including pulverization, extraction, filtration, freeze-drying, and further pulverization, to obtain high-purity dried powder products.

[0003] For example, patent CN121422525A discloses a small laboratory Ganoderma lucidum polysaccharide extraction device. This device stirs the polysaccharide components precipitated from Ganoderma lucidum fragments near the inner ring of the heating ring to reduce the stickiness. During the rotation of the rotating rod, multiple impellers on each rotating rod rotate, increasing the stirring range of the rotating rod. The impellers have the effect of enhancing the stirring, which is conducive to the flow of the fluid polysaccharide next to the inner ring of the heating ring, thereby increasing the extraction amount of polysaccharide. Existing polysaccharide extraction devices also have the following drawbacks: (1) Usually, only a single or a few processes can be automated, and it is impossible to achieve the integrated automated processing of the entire process from centrifugation to freeze drying to pulverization and bottling. In the extraction experiment of polysaccharides and peptides, it is usually necessary to complete centrifugation, filtration, freeze drying, pulverization and dispensing in sequence. The material transfer between each step depends on manual operation, which is not only inefficient, but also increases the risk of contamination and loss due to sample exposure. Although there are devices that integrate processes such as filtration, washing and drying, these devices are mainly for the industrial production of peptide raw materials. They are complex in structure and have high cost, and are not suitable for laboratory or small-batch production scenarios. (2) When processing different batches of materials, it is difficult to meet the needs of different processing volumes. The extraction experiments of polysaccharides and peptides often involve samples of different quantities. However, the size of existing freeze-drying trays is usually fixed. When the processing volume is small, an oversized tray will cause energy waste, and the material layer per unit area is too thin, which will affect the freeze-drying efficiency. When the processing volume is large, an undersized tray cannot meet the volume requirements. Although there are freeze-drying trays with adjustable depth or free combination in the existing technology, such solutions usually require manual disassembly or adjustment and cannot automatically switch between different sizes of trays according to the material quantity. (3) Before freeze drying, the material needs to be evenly spread on the surface of the tray to ensure that the moisture is evenly released during the freeze drying process. However, existing equipment mostly relies on operators to manually smooth the material, which not only increases the manual operation steps, but also makes it difficult to guarantee the uniformity of smoothing, affecting the subsequent freeze drying efficiency and quality. Especially when facing materials of different quantities, the thickness and area of ​​the material need to be adjusted accordingly. Existing laboratory equipment generally lacks adaptive adjustment capabilities.

[0004] Based on this, the present invention designs an extraction device for extracting juice in biological experiments to solve the above problems. Summary of the Invention

[0007] Compared with the prior art, the present invention has the following advantages: 1. Through the sample containing mechanism, when the amount of polysaccharide peptides to be separated and purified is small, the first driving component in the switching assembly controls the inner core to rotate 180 degrees to move the second containing tank and the smaller diameter tray to the top; when the amount of polysaccharide peptides to be separated and purified is large, the first driving component in the switching assembly controls the inner core to rotate 180 degrees to move the first containing tank and the larger diameter tray to the top, thus having the feature of automatically switching different sized trays according to the amount of polysaccharide peptides extracted; 2. The present invention, through the combination of sample transfer mechanism and sample containment mechanism, can not only control the sample containment mechanism to automatically switch positions between the filtration separation chamber, freeze-drying chamber, pre-crushing chamber and powdering chamber; it can also sequentially move the containment bottle to the bottom of the powdering chamber, thereby improving the working efficiency of polysaccharide and polypeptide extraction. 3. This invention, through the combination of an adjustable uniform distribution component and a sample containing mechanism, allows the first containing slot to be positioned at the top when the amount of polysaccharide peptides is large. After the first telescopic component in the switching component adjusts the tray upward to a preset height via the lifting plate and the central rod, the fourth driving component controls the second telescopic component, the sealing plug, and the rotating rod to rotate. The rotating rod controls the smoothing rod to move along the horizontal guide hole via a two-bar linkage, which is used to compensate for the insufficient length of the smoothing rod being smaller than the first containing slot and the radius of the internal tray. This allows the coarse particles of polysaccharide peptides to be evenly distributed on the surface of a larger tray, making it suitable for trays of different sizes and improving the efficiency and quality of subsequent freeze-drying of polysaccharide peptides. 4. This invention, through the combination of a pre-crushing component and a pulverizing component, allows the pre-crushing component to break polysaccharides and peptides into small pieces using a pressing block before pulverization, facilitating their automatic placement into the grinding chamber. During pulverization, the third telescopic component controls the limiting groove of the pressing block to fit onto the protruding structure above the grinding roller, and the fifth driving component controls the rotation of the pressing block, grinding roller, and spiral conveyor rod, achieving synchronous pulverization and feeding, thus improving the efficiency of polysaccharide and peptide extraction.

The fixed end of the first telescopic member 236 is fixedly installed in the inner core 221. The lifting plate 235 is fixedly connected to the movable end of the first telescopic member 236. The central rod 231 is rotatably connected to the surface of the lifting plate 235. The first telescopic member 236 is an electric telescopic rod. The freeze-drying chamber 5 is equipped with a telescopic sealing cover 51, which can fit against the upper surface of the outer shell 21. The telescopic sealing cover 51 includes a hydraulic telescopic rod and a sealing cover.

In this embodiment, when an extraction device for extracting juice in biological experiments is in operation, by setting the switching component 22, when the amount of polysaccharide peptides to be separated and purified is small, the first driving component 222 in the switching component 22 controls the inner core 221 to rotate 180 degrees, which is used to move the second receiving tank 224 and the smaller diameter tray 232 to the top; when the amount of polysaccharide peptides to be separated and purified is large, the first driving component 222 in the switching component 22 controls the inner core 221 to rotate 180 degrees, which is used to move the first receiving tank 223 and the larger diameter tray 232 to the top, which has the feature of automatically switching different sized trays 232 according to the amount of polysaccharide peptides extracted; After the polysaccharide peptides that have clumped in the tray 232 are pre-crushed in the pre-crushing chamber 6, the design of the first drive component 222 in the switching component 22 to control the inner core 221 to rotate 180 degrees can automatically discharge the pre-crushed polysaccharide peptides from the opening 211 under the outer shell 21 into the powdering chamber 7.

Before using tray 232, the disinfection nozzle 8 in the waste liquid chamber 121 can also spray disinfectant on the tray 232 located below. By controlling the tray 232 to rotate at a uniform speed through the rotating part and controlling the tray 232 to move up and down through the lifting part, the cleaning and disinfection effect can also be improved.

[0013] Example 2: In some embodiments, such as Figures 1-12 As shown in the preferred embodiment of the present invention, the sample transfer mechanism 3 includes a third driving member 31, an upper rotating shell 32, a rotating shaft 34, and a lower rotating shell 33.

On the one hand, it controls the sample containing mechanism 2 to automatically switch positions between the filtration separation chamber 4, the freeze-drying chamber 5, the pre-crushing chamber 6, and the powdering chamber 7. On the other hand, when it is necessary to load the polysaccharide and polypeptide powder in the powdering chamber 7 into several containing bottles 9 in batches, the containing bottles 9 can be moved sequentially to the bottom of the powdering chamber 7. The loading and unloading port 122 of the bottom shell 12 has a structure that is wider at the top and narrower at the bottom, and the narrower area at the bottom is a sedimentation tank. The depth of the sedimentation tank is greater than the height of the containing bottle 9. When the containing bottle 9 passes the sedimentation tank, it can fall under the action of gravity, making it easy for the staff to take it out.

[0015] Example 3: In some embodiments, such as Figures 3-11As shown, in a preferred embodiment of the present invention, a centrifuge cylinder 41 is rotatably connected inside the filtration separation chamber 4. The centrifuge cylinder 41 is driven to rotate at high speed by an independent drive module. The specific structure of the drive module is not described in detail. A discharge channel 43 is fixedly connected below the filtration separation chamber 4. The discharge channel 43 has a Y-shaped cross section. The Y-shaped discharge channel 43 includes a narrower straight channel at the top and a wider horn cover at the bottom, which are integrally formed. An adjustable distribution assembly 42 is installed inside the filtration separation chamber 4. The adjustable distribution assembly 42 includes a fourth driving component 421, a second telescopic component 422, a sealing plug 423, a rotating rod 424, a double connecting rod 425, a U-shaped frame 426, a smoothing rod 427, and a limiting block 4271. The fourth driving component 421 is fixedly installed on the top of the filtration separation chamber 4. The fixed end of the second telescopic component 422 is fixedly connected to the output end of the fourth driving component 421. The sealing plug 423 is fixedly connected to the movable end of the second telescopic component 422. One end of the rotating rod 424 is fixedly connected to the sealing plug 423. The other end of the moving rod 424 is hinged to one end of the connecting rod 425. The connecting rod 425 consists of two straight rods that are hinged to each other. The other end of the connecting rod 425 is hinged to a smoothing rod 427. The shaped frame 426 is slidably connected below the discharge channel 43. A horizontal guide hole 4261 is opened on the surface of the shaped frame 426. The smoothing rod 427 is slidably connected in the horizontal guide hole 4261. A limit block 4271 is fixedly installed on the surface of the smoothing rod 427. The upper and lower sides of the horizontal guide hole 4261 are in sliding contact with the limit block 4271. The length of the smoothing rod 427 is not greater than the minimum radius of the second receiving groove 224. In this embodiment, the fourth driving component 421 includes a fourth driving motor and a rotating seat. The fourth driving motor is fixedly installed on the top of the filtration separation chamber 4, and the rotating seat is fixedly installed on the output end of the fourth driving motor. The second telescopic component 422 is an electric telescopic rod, and the fixed end of the electric telescopic rod is fixedly connected to the rotating seat. During the centrifugal filtration stage, the second telescopic component 422 moves the sealing plug 423 to the top of the discharge channel 43 to seal it. When the polysaccharide peptide is discharged, the second telescopic component 422 moves the sealing plug 423 into the horn cover. The smoothing rod 427, which descends synchronously with the sealing plug 423, drives the C-shaped frame 426 to move downward synchronously through the limiting block 4271 until the smoothing rod 427 enters the vent. The first receiving groove 223 or the second receiving groove 224 stops after reaching a certain depth; when the amount of polysaccharide peptide is small, the second receiving groove 224 is located at the top. The first telescopic component 236 in the switching component 22 adjusts the tray 232 upward to a preset height through the lifting plate 235 and the central rod 231, which is used to adjust the distance between the tray 232 and the smoothing rod 427, thereby adjusting the distribution thickness of the polysaccharide peptide on the surface of the tray 232. During the process of the second driving component 233 and the transmission tube 234 in the rotating part controlling the rotation of the tray 232 through the central rod 231, the smoothing rod 427 is used to smooth the coarse particles of polysaccharide peptide on the surface of the tray 232, so that they are evenly distributed on the surface of the tray 232. When the amount of polysaccharide peptides is large, the first receiving tank 223 is located at the top. After the first telescopic component 236 in the switching component 22 adjusts the tray 232 upward to a preset height through the lifting plate 235 and the central rod 231, the fourth driving component 421 controls the second telescopic component 422, the sealing plug 423 and the rotating rod 424 to rotate. The rotating rod 424 controls the smoothing rod 427 to move along the horizontal guide hole 4261 through the two connecting rods 425. This is used to compensate for the fact that the length of the smoothing rod 427 is smaller than that of the first receiving tank 223 and the radius of the inner tray 232, so that the coarse particles of polysaccharide peptides can be evenly distributed on the surface of the larger tray 232, thereby improving the efficiency and quality of subsequent freeze-drying of polysaccharide peptides. It should be noted that the centrifugal force generated when the rotation speed of the sealing plug 423 is different is different. After the falling polysaccharide peptides come into contact with the sealing plug 423, they can also adjust the scattering area of ​​the coarse polysaccharide peptide particles, further improving the uniformity of the distribution of coarse polysaccharide peptide particles on the surface of the tray 232.

[0016] Example 4: In some embodiments, such as Figures 3-12As shown, in a preferred embodiment of the present invention, a pre-crushing assembly 61 is installed in the pre-crushing chamber 6. The pre-crushing assembly 61 includes a pressing block 611, a sealing cover 612, a fifth driving member 613, and a third telescopic member 614. The fixed end of the third telescopic member 614 is fixedly connected to the top of the pre-crushing chamber 6. The fifth driving member 613 is fixedly connected to the movable end of the third telescopic member 614. The output end of the fifth driving member 613 is fixedly connected to the sealing cover 612. The pressing block 611 is fixedly installed below the sealing cover 612. A limit groove 615 is formed on the lower surface of the pressing block 611. The third telescopic member 614 is an electric telescopic rod. A support is fixedly connected to the movable end of the electric telescopic rod. The fifth driving member 613 is a fifth driving motor. The fifth driving motor is fixedly installed on the support. The sealing cover 612 is fixedly connected to the output end of the fifth driving motor. The grinding chamber 7 is equipped with a grinding assembly 71, which includes a grinding roller 711, a spiral conveying rod 712, and a protruding structure 713.

[0017] In this embodiment, when the sample receiving mechanism 2 moves to below the pre-crushing chamber 6, the first telescopic member 236 first moves the tray 232 to the bottom of the first receiving groove 223 or the second receiving groove 224 to prevent the tray 232 from deforming under force during the subsequent pressing process. Then, the third telescopic member 614 controls the pressing block 611, the sealing cover 612, and the fifth driving member 613 to move downwards. The pressing block 611 presses the polysaccharide polypeptide on the tray 232, breaking it from a whole into small pieces, which is convenient for subsequent grinding in the powdering chamber 7. The sealing cover 612 is used to seal the opening 211 to prevent powder from splashing during the crushing process. Then, the first driving member 222 controls the inner core 221 to rotate 180 degrees for... The polysaccharide peptides, broken into small pieces, are fed into the grinding chamber 7. Then, the upper rotating shell 32 and the lower rotating shell 33 are rotated by the third drive 31 to move the sample receiving mechanism 2 below the filtration separation chamber 4. Next, the limiting groove 615 on the surface of the pressing block 611 is fitted onto the protrusion 713 above the grinding roller 711 by the third telescopic member 614. The sealing cover 612 is used to seal the grinding chamber 7. Then, the pressing block 611, the grinding roller 711 and the spiral conveyor 712 are rotated by the fifth drive 613. The rotating grinding roller 711 is used to grind the polysaccharide peptides into powder, and the rotating spiral conveyor 712 conveys the powder from the feeding channel to the receiving bottle 9 below.
