Description

Technical Field

[0001] The invention relates to an extraction device, in particular to a yam polysaccharide extraction device. Background Art

[0002] A large number of studies have shown that yam polysaccharide is one of the main active ingredients of yam, and has biological activities both in vivo and in vitro, including antioxidant, hypoglycemic, anti-tumor and immunity enhancement. As a natural active substance with broad application prospects, yam polysaccharide plays an important role in improving and improving human functions. With the deepening of scientific research and the advancement of technology, the extraction and application technology of yam polysaccharide will continue to improve, and its application prospects will be broader. We should strengthen the research and development of yam polysaccharide, give full play to its application value in the fields of medicine, food, cosmetics, etc., and make greater contributions to human health.

[0003] The extraction of yam polysaccharides is a complex process involving multiple steps. Select fresh, non-moldy, non-worm-eaten yam as the raw material, and wash it thoroughly to remove surface soil and impurities. The washed yam is crushed or mashed to form a coarse powder or mud for subsequent extraction. Add water to the yam coarse powder or mud material and boil it at a suitable temperature for extraction. During this process, constant stirring is required to prevent sticking to the pan, and it should be continued for a certain period of time to ensure that the polysaccharide is fully dissolved. Filtration and repeated extraction: Filter the boiled material and collect the filtrate. Further treat the filter residue and perform one or more boiling extractions to increase the extraction rate of polysaccharides. Combine the filtrates from multiple extractions. Concentrate the combined filtrate, and then add an appropriate amount of ethanol to precipitate the polysaccharide. Collect the precipitate by centrifugation or other methods, and dry it to obtain yam polysaccharides.

[0004] When extracting yam polysaccharides, a series of various equipment, such as crushers, mixers, filters, concentrators, etc., are used to participate in the extraction process. The yam needs to be transferred back and forth between various equipment to finally obtain the extracted yam polysaccharides. The entire extraction process is very cumbersome, time-consuming and labor-intensive, and there will also be various losses to the yam raw materials.

DETAILED DESCRIPTION

[0033] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present application.

[0034] The embodiment of the present application provides a yam polysaccharide extraction device.

[0035] Embodiment 1, as Figure 1-5 shown.

[0036] A yam polysaccharide extraction device comprises a cleaning component 1.

[0037] The cleaning assembly 1 includes a cleaning box 11 , a box cover 12 , a cleaning frame 13 , a swing motor 14 , a fixed cleaning plate 15 , and a cleaning nozzle 16 .

[0038] The cleaning box 11 is a box structure with an open top. The top of the cleaning box 11 is rotatably connected to the box cover 12. The bottom of the box cover 12 is installed with the fixed cleaning plate 15. The bottom of the fixed cleaning plate 15 is installed with a plurality of cleaning nozzles 16.

[0039] The cleaning box 11 is internally rotatably connected to the cleaning frame 13. Open the box cover 12, and put the yam into the cleaning frame 13 for cleaning. The cleaning frame 13 is a hollow semi-cylindrical structure with an open top surface. The swing motor 14 is installed on the outside of the cleaning box 11. The output shaft of the swing motor 14 extends to the inside of the cleaning box 11 and is fixedly connected to the cleaning frame 13. When cleaning the yam, the swing motor 14 works in forward and reverse rotations, driving the cleaning frame 13 to rotate left and right, thereby causing the yam to rotate in the cleaning frame 13, so that each surface can be flushed with cleaning water, and the cleaning is cleaner; at the same time, when the cleaning frame 13 rotates, it will also drive the yams to rub and collide with each other, and the stubborn soil will be constantly washed, rubbed, and then washed again, so that the yam is cleaned more cleanly.

[0040] Furthermore, the cleaning component 1 also includes a movable cleaning shaft 17 and a telescopic push rod 18. The telescopic push rod 18 is installed on the bottom surface of the box cover 12, and the movable cleaning shaft 17 is installed on the output end of the telescopic push rod 18. A plurality of nozzles are arranged on the surface of the cleaning shaft 17. During cleaning, the telescopic push rod 18 drives the movable cleaning shaft 17 to extend into the inner side of the cleaning frame 13 to flush the yam at a close distance, so that the stubborn soil on the surface of the yam can be more easily flushed clean.

[0041] The cleaning shaft 17 and the cleaning plate are both connected to an external water source for water supply.

[0042] The bottom surface of the cleaning box 11 is provided with a connecting groove 19, and a gate valve 191 is provided on one side of the connecting groove 19. A waste water pipe 111 is installed on one side of the connecting groove 19. The waste water after cleaning is discharged from the waste water pipe 111. When the yam is cleaned, the gate valve 191 is opened, and the swing motor 14 drives the cleaning frame 13 to flip, and the yam falls down through the connecting groove 19 to enter the next step.

[0043] A yam polysaccharide extraction device comprises a crushing component 2 installed below the cleaning component 1. The washed yam is crushed.

[0044] The crushing assembly 2 includes a crushing box 21 , a crushing motor 22 , a crushing shaft 23 , a crushing knife 24 , a pulley 25 , and a belt 26 .

[0045] The crushing box 21 is installed below the cleaning component 1, and the washed yam falls into the crushing box 21 from the connecting groove 19 to be crushed. The crushing box 21 is a hollow box structure that is open at the top and bottom. A plurality of crushing shafts 23 are rotatably connected inside the crushing box 21, and a plurality of crushing knives 24 are arranged at equal intervals on the crushing shafts 23. The crushing motor 22 is installed outside the crushing box 21, and the output shaft of the crushing motor 22 extends into the crushing box 21 and is fixedly connected to any of the crushing shafts 23. The pulleys 25 are arranged at one end of two adjacent crushing shafts 23, and the belts 26 are installed outside the two pulleys 25. When the crushing motor 22 works, it drives the crushing shafts 23 connected thereto to rotate, and then drives the other crushing shafts 23 to rotate through the pulleys 25 and the belts 26, and the yam is crushed by the crushing knives 24 on the surface of the crushing shafts 23.

[0046] There are three crushing shafts 23, which are arranged in a herringbone shape. The top crushing shaft 23 is located directly below the connecting groove 19. The yam falling into the crushing box 21 is first crushed by the crushing blades 24 on the crushing shaft 23. The crushed yam falls onto the crushing shafts 23 on both sides, and is then crushed by the crushing blades 24 on the crushing shafts 23 on both sides. After multiple crushings, the yam raw material reaches the crushing coarseness requirement.

[0047] A pair of convergence plates 27 are installed on the upper part of the inner cavity of the crushing box 21, and the two convergence plates 27 are in an inverted eight-shaped structure to prevent the yam falling into the crushing box 21 from bypassing the uppermost crushing shaft 23.

[0048] A yam polysaccharide extraction device comprises a concentration component 3 installed below the cleaning component 1. The yam is boiled, extracted and concentrated to ensure that the polysaccharide is fully dissolved.

[0049] The concentrating assembly 3 includes a concentrating box 31, a converging slope 32, and a heating wire 33. The concentrating box 31 is installed below the pulverizing assembly 2. The concentrating box 31 is a box structure with an open top. The converging slopes 32 are respectively arranged on both sides of the bottom of the inner cavity of the concentrating box 31. A converging groove 321 is formed between the two converging slopes 32. A heating wire 33 is installed on the surface of the converging slope 32. The concentrating assembly 3 also includes a water injection plate 36 and a water injection nozzle 37. The water injection plate 36 is installed on the inner side of the pulverizing assembly 2. A plurality of water injection nozzles 37 are installed on the surface of the water injection plate 36. A guide groove 34 is provided on the side wall of the concentrating box 31 on one side of the converging groove 321. A guide valve 35 is installed at the outlet of the guide groove 34.

[0050] Water is added into the crushing box 21 through the water injection plate 36. The water passes through the crushing box 21 and the crushing shaft 23, and the yam raw materials adhered to the surface can be washed into the concentration box 31, which greatly reduces the loss of yam raw materials. When the water in the concentration box 31 and the yam raw materials are approximately 1:4, the water injection can be stopped, and the heating wire 33 is started to boil the mixture of yam and water to dissolve the polysaccharide.

[0051] A yam polysaccharide extraction device comprises a filtering component 4 installed inside the concentration component 3. The crushed yam falls into the filtering component 4.

[0052] The filter assembly 4 includes a filter box 41 and a filter box cover 42. The filter box 41 is installed inside the concentration box 31. The filter box 41 is a hollow box structure with an open top surface. The filter box 41 is a mesh structure. The filter box covers 42 are rotatably connected to both sides of the filter box 41. An operating door 43 is installed on one side of the concentration box 31. The filter box 41 is located directly below the crushing shaft 23. The yam is crushed by the crushing shaft 23 and the crushing knife 24 of the crushing box 21 and directly falls into the filter box 41 inside the concentration box 31. After the crushing is completed, water is injected, and the water flushes the adhered yam raw materials into the filter box 41. After the water injection is completed, the operating door 43 is opened and the filter box cover 42 is closed. During the boiling and extraction process of the mixture of yam and water, the yam raw materials are always in the filter box 41, and the water can flow out of the filter box 41 normally. This prevents the yam raw material from adhering to the bottom of the inner cavity of the concentration box 31 and the surface of the heating wire 33 during the boiling process.

[0053] Lifting components 5 are installed on both sides of the filtering component 4 to control the rise and fall of the filtering component 4. During the extraction and concentration process, the filtering component 4 is lowered until the water covers the yam raw material.

[0054] The lifting assembly 5 includes a winch 51, a driving rope 52, and a connecting rope 53. The winch 51 is installed on both sides of the concentration box 31. The driving rope 52 is installed on the output end of the winch 51. Connecting holes are opened on both sides of the concentration box 31. The driving rope 52 passes through the connecting holes and extends to the inside of the concentration box 31, and is fixedly connected to the connecting rope 53. The other end of the connecting rope is fixedly connected to the side wall of the filter box 41. The winch 51 drives the driving rope 52 and the connecting rope 53 to pull up or lower the filter box 41, so that the filter box 41 is submerged in water or pulled out of the water. Two connecting ropes 53 are arranged on the same side, so that the filter box 41 will not tip over or flip over during the rising and falling process.

[0055] After the crushing is completed, the water injection plate 36 starts to inject water, and the water flushes the adhered yam raw materials into the filter box 41. After the water injection is completed, the operating door 43 is opened and the filter box cover 42 is closed. At this time, the winch 51 is started, the filter box 41 is placed in water, the heating wire 33 is started, and the mixture of yam and water is boiled to dissolve the polysaccharide. The boiling time is controlled according to the actual situation, generally 3 hours. After the boiling time is reached, the filter box 41 is lifted, the filter box cover 42 is opened, and the water injection plate 36 continues to inject water. At this time, the stubborn yam raw materials adhered to the crushing box 21, the crushing shaft 23, and the crushing knife 24 are washed into the filter box 41 by the water sprayed by the water injection plate 36 after a period of steam fumigation. After the water injection is completed, the above operation is repeated. The boiling extraction process is repeated many times, generally 3 times. Until the polysaccharide is fully dissolved.

[0056] When the present invention is used:

[0057] 1. Select fresh yam without mildew, deterioration or insect infestation as raw material, open the box cover, put the yam into the cleaning frame, and start the cleaning operation.

[0058] During cleaning, the telescopic push rod drives the movable cleaning shaft to extend into the inner side of the cleaning frame, and the cleaning shaft and the fixed cleaning plate start to spray water to clean the yam. At the same time, the swing motor starts to drive the cleaning frame to rotate forward and reverse, so that all surfaces of the yam will be washed by water, and the waste water after cleaning will be discharged from the waste water pipe.

[0059] 2. After the yam is cleaned, the gate valve is opened, the swing motor is started, and the yam is poured out, so that the yam falls from the connecting groove into the crushing box below. At this time, the crushing motor is started, and the yam falling into the crushing box is first crushed by the crushing knife of the crushing shaft above, and the crushed yam falls to the crushing shafts on both sides, and then is crushed by the crushing knives on the crushing shafts on both sides. After multiple crushings, the yam raw material meets the crushing coarseness requirement, and the crushed yam falls into the filter box.

[0060] 3. After the yam is crushed, the water injection plate starts to inject water, and the water flushes the adhered yam raw materials into the filter box. After the water injection is completed, open the operating door and close the filter box cover. At this time, the winch is started, the filter box is placed in water, the heating wire is started, and the mixture of yam and water is boiled to dissolve the polysaccharide. The boiling time is controlled according to the actual situation, generally 3 hours. After the boiling time is reached, the filter box is lifted, the filter box cover is opened, and the water injection plate continues to inject water. At this time, the stubborn yam raw materials adhered to the crushing box, the crushing shaft, and the crushing knife are washed into the filter box by the water sprayed by the water injection plate after a period of steam fumigation. After the water injection is completed, repeat the above operation. The boiling extraction process is repeated many times, generally 3 times. Until the polysaccharide is fully dissolved.

[0061] 4. After the boiling extraction is completed, the winch is started to pull up the filter box to concentrate the filtrate in the concentration box. The heating wire is started to concentrate the filtrate.
