Description

Technical Field

[0001] The utility model relates to the field of plant extraction, in particular to a sweet potato vine component extraction device. Background Art

[0002] Sweet potato vine has the health functions of stopping bleeding, stopping diarrhea, promoting menstruation, lowering blood sugar, improving immunity, raising platelets, preventing and treating night blindness, etc. When extracting the components of sweet potato vine, fresh or dried sweet potato vine is put into the washing unit for washing, and then sent to the cutting unit for cutting. The cut sweet potato vine is sent to the extraction equipment, and a suitable solvent (such as water, ethanol, etc.) is added. Extraction is carried out according to the preset temperature and time. The extract is filtered to remove larger solid particles, and then separated into finer solid residues and liquid components by a centrifuge. The liquid component is preliminarily purified by a chromatographic column to remove most impurities, and then enters the evaporator for concentration, and finally a higher purity extract is obtained. The existing The sweet potato vine extraction device, when in use, first of all has a poor pre-treatment and cleaning effect on the sweet potato vine raw material. Generally, the cleaning is carried out by stirring in a stirring barrel, which causes the sweet potato vines to squeeze and rub against each other, which may cause some parts to not be cleaned or not cleaned thoroughly, leaving impurities. At the same time, when the sweet potato vines are worn due to friction, some biologically active ingredients may be lost, such as polyphenols, flavonoids, etc. These ingredients may be dissolved or worn away by water during the cleaning and friction process, thereby affecting the composition and quality of the final extract. Finally, the nutritional components and structure of the sweet potato vine extract are destroyed, which brings a lot of trouble to people. This is far from meeting the current requirements of people for the product. Utility Model Content

A through hole is opened at the top of the cylinder 402, and the pull rod 408 and the cylinder 402 are slidably connected through the through hole. A connecting pipe is fixed to the surface of the T-tube 202, and connecting pipes 401 are fixed at both ends of the connecting pipe. The bottom end of the cylinder 402 is fixedly connected to the connecting pipe 401 through the exhaust pipe, and a control valve is installed inside the connecting pipe. 409, a spring 2 405 is fixedly installed between the piston 404 and the gas cylinder 402, a spring 2 405 is fixedly installed between the piston 404 and the gas cylinder 402, a sealing ring is fixedly arranged on the outer surface of the piston 404, a flip plugging component 5 is installed on the truncation component 3, and the flip plugging component 5 includes a limit block 501, a lock ear 502 and a lock buckle 503. The center position of the rectangular plate 302 is hinged with the two groups of strip plates 301 through a hinge shaft, and the upper surface of the strip plate 301 is rotatably connected with two groups of limit blocks 501 arranged symmetrically through a bearing, and the bottom of the limit block 501 is connected to the The upper surfaces of the rectangular plates 302 are fitted together, and the sides of the two groups of strip plates 301 that are away from each other are fixed with locking ears 502 by screws. The surface of the cleaning box 1 close to the locking ears 502 is fixed with locking buckles 503 by screws. The locking ears 502 and the locking buckles 503 correspond to each other up and down, and can separate the sweet potato vines on the top of the filter baffle from the water, so as to facilitate the subsequent drying operation. At the same time, the sweet potato vines can be blocked to avoid the impact force generated during the air blowing process, which will blow the sweet potato vines out and be contaminated with impurities again, thereby further improving the use effect of the device and meeting actual use needs.

[0032] When extracting the components of the sweet potato vine, first put the sweet potato vine into the interior of the cleaning box 1, then press the rectangular plate 302, thereby driving the two groups of strip plates 301 to slide on the surface of the limiting slide rod 303, and at the same time compressing the spring 1 304, through the downward movement of the rectangular plate 302, and driving the cutting blade 305 to move downward until the cutting blade 305 moves to the interior of the cleaning box 1. Since the sweet potato vine is blocked by the filter partition 203, the sweet potato vine can be cut off, and the longer sweet potato vine can be cut into small sections of appropriate length, which can reduce friction and damage during cleaning. Then, the rectangular plate 302 is moved up, and the cutting blade 305 is driven to move up synchronously, and the cutting blade 305 is removed from the cleaning box 1, and then salt water is injected into the cleaning box 1 to make the cleaning box 1 clean. The salt water is injected to a certain height, the injection is stopped, and then the air pump 201 is started, and the gas generated is transported to the inside of the T-tube 202 and discharged to the filter partition 203 through the T-tube 202. The gas discharged from the air pipe 204 generates a large number of bubbles in the salt water. The bubbles generated by the high-pressure gas in the bubble cleaning can better penetrate into the fine structure of the sweet potato vine, thereby achieving a deeper cleaning effect. Compared with the barrel stirring cleaning, the friction between the sweet potato vines during the bubble cleaning process is less, which can effectively reduce the damage to the sweet potato vines and avoid the loss of some biologically active ingredients in the sweet potato vines due to wear. The nutrients and structure of the sweet potato vine extract will not be destroyed, which further improves the use effect of the device. When the cleaning is completed, by beating Open the control valve 409. At this time, the gas inside the T-tube 202 enters the inside of the connecting pipe 401 and is discharged into the inside of the air cylinder 402. As the gas is continuously rushed into the air cylinder 402, the piston 404 is lifted up, and the pull rod 408 is driven to move upward, and the filter baffle 203 is driven to move upward synchronously, so that the sweet potato vines on the top of the filter baffle 203 can be separated from the water, so as to facilitate the subsequent drying operation and further improve the use effect of the device. As the piston 404 moves upward and the spring 2 405 is stretched, when the air supply to the air cylinder 402 is stopped, the rebound force of the spring 2 405 can quickly drive the piston 404 to reset, and then drive the filter baffle 203 to reset. At the same time, the piston 404 moves upward When the air cylinder 402 is located at the top space of the piston 404, the gas in the one-way exhaust valve 2 407 is discharged. At the same time, when the piston 404 moves downward, the gas inside the air cylinder 402 is discharged through the one-way exhaust valve 1 406. As the filter baffle 203 continues to move upward, the water level drops and the water level is lower than the height of the air nozzle. At this time, the gas from the air pump blows toward the filter baffle 203. The generated wind force can achieve a drying effect. While blowing and drying, the limit block 501 is bent to separate the limit block 501 from the rectangular plate 302, and the rectangular plate 302 is folded at the same time, so that the rectangular plate 302 turns the cutting piece 305 to the top, and then the limit block 501 is bent again to fit the surface of the rectangular plate 302 and limit the rectangular plate 302.To avoid rotation, the strip plate 301 is pressed to drive the rectangular plate 302 downward, and then the lock buckle 503 is buckled on the lock ear 502 to lock the position of the strip plate 301 and the rectangular plate 302. Through this operation, the sweet potato vines can be blocked to avoid the impact force generated during the air blowing process, which will blow the sweet potato vines out and contaminate them with impurities again, thereby further improving the use effect of the device and meeting the actual use needs. The dried sweet potato vines are then cut and sent to the extraction equipment (not shown in the figure) for extraction according to the preset temperature and time.

[0033] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
