[0001] The utility model relates to the technical field of pretreatment equipment, and particularly relates to a raw material pretreatment device for polysaccharide extraction. Background Art

[0002] The physiological functions of polysaccharides from natural sources are closely related to their purity and chemical structure. To obtain polysaccharides with high content, high purity, and stable structure, pretreatment is particularly important in polysaccharide extraction. Pretreatment is not only a key link in the polysaccharide extraction process but also the basis for ensuring the high quality of polysaccharides, and thus a key factor in exerting their wide applications and unique effects.

[0033] The physiological functions of polysaccharides from natural sources are closely related to their purity and chemical structure. To obtain polysaccharides with high content, high purity, and stable structure, pretreatment is particularly important in the extraction of polysaccharides. Pretreatment is not only a key link in the polysaccharide extraction process but also the basis for ensuring high-quality polysaccharides, and thus a key factor in exerting their wide applications and unique effects. The purpose of pretreatment technology is to break the cell walls and cell structures of polysaccharide extraction raw materials, increase the porosity of substances and the specific surface area of contact, so that polysaccharides can be fully dissolved, thereby improving the extraction rate and purity of polysaccharides and maintaining the stability of the polysaccharide structure and properties. Therefore, it is very necessary to perform certain pretreatment on polysaccharide extraction raw materials to obtain high-quality and high-content polysaccharides. After the pretreatment of polysaccharide extraction raw materials, solid-liquid separation is also required to remove the pretreatment liquid to obtain the raw materials for subsequent polysaccharide extraction. Currently, the devices for pretreatment of polysaccharide extraction raw materials have the following problems: Pretreatment liquids such as ethanol solution need to infiltrate and diffuse into the cells of Chinese herbal medicine raw materials to contact lipophilic and alcohol-soluble substances to achieve chemical cell wall breaking, which takes a long time and has low efficiency.

[0034] To solve the above problems, the present utility model proposes a raw material pretreatment device for polysaccharide extraction, aiming to provide a raw material pretreatment device for polysaccharide extraction that can quickly break the cell walls of raw materials. Figures 1 to 2 FIG. is a schematic structural diagram of an embodiment provided by a raw material pretreatment device for polysaccharide extraction according to the present utility model.

[0035] Please refer to Figures 1 to 2 , the present utility model proposes a raw material pretreatment device 1000 for polysaccharide extraction, which includes a first box body 1 and a crushing device 2; a first accommodating cavity 11 is arranged inside the first box body 1 for accommodating raw materials and pretreatment liquids; the crushing device 2 includes a crushing member 21 installed in the first accommodating cavity 11 for crushing the raw materials.

[0036] In the technical solution of the present utility model, through the crushing member 21, the raw materials accommodated in the first accommodating cavity 11 are physically crushed, so as to accelerate the contact between pretreatment liquids such as ethanol liquid and the fat-soluble and alcohol-soluble substances inside the cells of the raw materials, thereby realizing chemical cell wall breaking. By means of physical means to cooperate with chemical cell wall breaking, the time consumption is less and the efficiency is high.

[0037] Further, the crushing device 2 further includes a first motor 22 and a rotating member 23; the first motor 22 is installed on one side end face outside the first box body 1; the rotating member 23 is accommodated in the first accommodating cavity 11 and is arranged in a long shape; the main shaft of the first motor 22 penetrates through the first box body 1 and is drivingly connected to any one of the two end faces of the rotating member 23 along the length direction; the crushing member 21 is fixedly installed along the circumferential side of the rotating member 23. It can be understood that, in order to further better enable the crushing member 21 to crush the raw materials, specifically, the crushing device 2 further includes the first motor 22 and the rotating member 23; the first motor 22 is installed on one side end face outside the first box body 1; the rotating member 23 is accommodated in the first accommodating cavity 11 and is arranged in a long shape; the main shaft of the first motor 22 penetrates through the first box body 1 and is drivingly connected to any one of the two end faces of the rotating member 23 along the length direction; the crushing member 21 is fixedly installed along the circumferential side of the rotating member 23. When the first motor 22 rotates, it drives the rotating member 23 to rotate at a high speed, and the crushing member 21 is installed along the circumferential side of the rotating member 23, that is, the crushing member 21 also rotates at a high speed in the first accommodating cavity 11 together with the rotating member 23, thereby physically crushing the raw materials inside the first accommodating cavity 11, so as to accelerate the contact between pretreatment liquids such as ethanol liquid and the fat-soluble and alcohol-soluble substances inside the cells of the raw materials, thereby realizing chemical cell wall breaking. By means of physical means for crushing and mixing, the technical effects of less time consumption and high efficiency are achieved.

[0038] Further, the crushing member 21 includes a first cutter group 211 and a second cutter group 212. The first cutter group 211 and the second cutter group 212 are arranged crosswise along the circumferential side of the rotating member 23, and the first cutter group 211 and the second cutter group 212 are arranged at an angle along the extending direction of the rotating member 23. It can be understood that, in order to further improve the efficiency of crushing raw materials, the crushing member 21 includes the first cutter group 211 and the second cutter group 212. The first cutter group 211 and the second cutter group 212 are arranged crosswise along the circumferential side of the rotating member 23, and the first cutter group 211 and the second cutter group 212 are arranged at an angle along the extending direction of the rotating member 23. Thus, the first cutter group 211 and the second cutter group 212 have a larger crushing range in space. Further, the angle between the first cutter group 211 and the second cutter group 212 is preferably controlled between 80° and 100°. The most preferred embodiment is that the included angle between the first cutter group 211 and the second cutter group 212 is 90°.

[0039] In addition, please refer to Figure 1 , and a filtering device 3 is further included for filtering the crushed raw materials in the first box body 1. It can be understood that after being crushed by the first cutter group 211 and the second cutter group 212, the raw materials are crushed to a size less than or equal to the pore size of the filter screen of the filtering device 3, and can be fully contacted with a pretreatment liquid such as ethanol solution to perform chemical cell wall breaking and dissolve impurities in the polysaccharide extraction raw materials.

[0040] Further, the filtering device 3 includes a filter screen 31, and the filter screen 31 is arranged at intervals along the inner wall end surface of the first box body 1. It can be understood that generally, a filtering device 3 is added to the bottom. However, in this embodiment, in order to accelerate the filtering of the raw materials inside the first accommodating cavity 11, the filtering device 3 includes a filter screen 31, and the filter screen 31 is arranged at intervals along the inner wall end surface of the first box body 1. Thus, not only does it have a filtering effect at the bottom, but also has a filtering effect on the side wall of the filtering device 3, thereby accelerating the filtering of the crushed raw materials inside the first accommodating cavity 11 and improving the pretreatment efficiency; in addition, the filtering function of the filter screen 31 is to roughly screen the solution in the first box body 1, that is to say, the filter screen 31 is used to control the upper limit of the particle size of the raw material pretreatment device for polysaccharide extraction; according to the needs of users, the filter screen 31 with different particle sizes can be replaced, and thus a roughly screened stock solution with different particle sizes can be obtained.

[0041] In addition, please refer to Figure 1, further comprising a second box body 4, which is connected to the first box body 1 in a penetrating manner and is internally provided with a second accommodating cavity 41 for accommodating the filtered slurry from the first box body 1. It can be understood that the mixed liquid of the crushed raw materials and the pretreatment liquid such as ethanol liquid needs to go through the next processing procedures to separate the impurity stock solution from the crushed raw material residues. Therefore, it is necessary to transfer the filtered slurry to the next processing device. Thus, the raw material pretreatment device 1000 for polysaccharide extraction further comprises the second box body 4, which is connected to the first box body 1 in a penetrating manner and is internally provided with the second accommodating cavity 41 for accommodating the filtered slurry from the first box body 1.

[0042] Furthermore, a connecting valve 42 is also provided at the penetrating connection between the first box body 1 and the second box body 4. It can be understood that the processing speed of the second box body 4 for the slurry may not be synchronized with the speed of the crushed raw materials in the first box body 1. Therefore, the connecting valve 42 is also provided at the penetrating connection between the first box body 1 and the second box body 4. When the slurry in the second box body 4 reaches its processing limit, the connecting valve 42 is closed to prevent the slurry from continuing to enter the second box body 4 so as not to affect the next process.

[0043] Furthermore, the second box body 4 further comprises a first outlet 43, a second outlet 44 and a separation device 45; the first outlet 43 and the second outlet 44 are respectively arranged at the bottom and the top of the second accommodating cavity 41; the separation device 45 is used for solid-liquid separation of the slurry. It can be understood that the slurry flowing from the first box body 1 into the second box body 4 includes the pretreatment stock solution with dissolved impurities and the crushed raw material residues. The internal impurities are only dissolved in the pretreatment liquid and need to be separated from the processed raw material residues to purify the raw materials. Therefore, the second box body 4 is also provided with the first outlet 43, the second outlet 44 and the separation device 45. The slurry is separated into a solid phase and a liquid phase by the separation device 45. The solid phase settles and is discharged from the first outlet 43, and the liquid phase is discharged from the second outlet 44, thereby achieving the effect of separating the pretreatment liquid phase rich in impurities and the processed solid-phase raw materials.

[0044] Furthermore, the separation device 45 includes a second motor 451, a vertical shaft 452, and a plurality of separation plates 453. The second motor 451 is installed at the bottom of the second box body 4. The vertical shaft 452 extends in the vertical direction, and the main shaft of the second motor 451 is drivingly connected to the vertical shaft 452. The plurality of separation plates 453 are arranged on the circumferential side of the vertical shaft 452. The separation plates 453 are inclined from top to bottom. It can be understood that in order to separate the filter slurry into a solid phase and a liquid phase, thus, the separation device 45 includes the second motor 451, the vertical shaft 452, and the plurality of separation plates 453. The second motor 451 is installed at the bottom of the second box body 4. The vertical shaft 452 extends in the vertical direction, and the main shaft of the second motor 451 is drivingly connected to the vertical shaft 452. The plurality of separation plates 453 are arranged on the circumferential side of the vertical shaft 452. The separation plates 453 are inclined from top to bottom. Thus, when the second motor 451 rotates at a high speed, driving the vertical shaft 452 to rotate at a high speed, the plurality of separation plates 453, due to being installed on the circumferential side of the vertical shaft 452 and the separation plates 453 being inclined from top to bottom, thus, the plurality of separation plates 453 also rotate at a high speed along with the vertical shaft 452. Furthermore, the filter slurry rotates at a high speed along with the separation plates 453. At this time, the heavier substances in the filter slurry will accelerate sedimentation during the rotation process and be discharged from the first outlet 43. The lighter part starts to slowly rise along with the centrifugal force of the rotation of the separation plates 453, is peeled off from the filter slurry, and then is discharged from the second outlet 44, thereby achieving the technical effect of separation.

[0045] In addition, please refer to Figure 1 , the first box body 1, the filter screen 31, and the second box body 4 are all made of polycarbonate material. It can be understood that the polycarbonate material is a visible transparent material. In this way, each process step can be clearly visible. For example, the situation of raw material crushing in the first box body 1, whether raw materials need to be added, the filtration condition, the state of filter slurry separation inside the second box body 4, etc., thereby realizing visual operation. Additionally, in other embodiments, other transparent materials can also be used.

[0046] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or any direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
