Description

Technical Field

[0001] The invention belongs to the technical field of polysaccharide extraction, and specifically relates to a preparation process and method of codonopsis pilosula polysaccharide extracted from codonopsis pilosula. Background Art

[0002] Polysaccharides are polymeric carbohydrates composed of sugar chains linked by glycosidic bonds, with at least more than 10 monosaccharides. Polysaccharides composed of the same monosaccharides are called homopolysaccharides, such as starch, cellulose and glycogen; polysaccharides composed of different monosaccharides are called heteropolysaccharides, such as gum arabic, which is composed of pentose and galactose. Polysaccharides are not a pure chemical substance, but a mixture of substances with different degrees of polymerization. Polysaccharides are generally insoluble in water, have no sweet taste, cannot form crystals, and have no reducing and mutarotation phenomena. Polysaccharides are also glycosides, so they can be hydrolyzed. During the hydrolysis process, a series of intermediates are often produced, and finally they are completely hydrolyzed to obtain monosaccharides.

The present invention puts the material into the feed port, and the active crushing roller rotates through the action of the first motor, and the sprocket in front of the active crushing roller rotates synchronously. Due to the mutual meshing of the sprocket and the chain, the active crushing roller and the driven crushing roller rotate synchronously, which can crush the objects entering the feed port.

[0018] Step S1, dust removal and cleaning: Rinse the medicinal material Codonopsis pilosula with clean water and set aside;

[0019] Step S2, crushing and filtering:

[0020] Step S21, the first motor is started to drive the crankshaft to rotate. Since the crankshaft is pin-connected to the movable push rod, the crankshaft drives the movable push rod to move back and forth left and right, thereby pushing the extrusion block to move back and forth left and right along the supporting slide rod under the action of the sliding sleeve block. The codonopsis enters the crushing bin from the feed inlet, is repeatedly hit by the extrusion block, and is crushed, and the juice inside is extracted and falls from the through hole;

[0021] Step S22, adding polysaccharide extract into the stirring chamber, the crushed Codonopsis pilosula pieces and juice fall into the stirring chamber together, the crankshaft rotates to drive the first bevel gear to rotate, and under the meshing action of the gears, the second bevel gear drives the fixed shaft to rotate, thereby rotating the first sprocket, and because the first sprocket is chain-driven by the first chain and the second sprocket, the first sprocket pushes the first chain to move under the action of friction, driving the second sprocket to rotate synchronously, so that the stirring shaft drives the stirring blade to rotate, and the polysaccharide extract and the Codonopsis pilosula juice are stirred and mixed, thereby accelerating the reaction;

[0022] Step S23, the mixture after stirring is filtered through the first filter plate. After filtering, the hydraulic cylinder is started to pull the first baffle plate upward, the stirring shaft rotates to drive the third sprocket to rotate, and the third sprocket is driven by the second chain and the fourth sprocket chain. Under the action of friction, the third sprocket pushes the second chain to move, driving the fourth sprocket to rotate, thereby rotating the eccentric wheel. Since the first filter plate is movably pinned to the main body of the extraction equipment, the first filter plate vibrates, and the broken pieces and residues on it enter the return bin from the return port;

[0023] Step S24, the second motor is started to drive the second conveying roller to rotate. Since the second conveying roller is chain-driven with the first conveying roller through the conveyor belt, the second conveying roller pushes the conveyor belt to move under the action of friction, so that the first conveying roller rotates synchronously, thereby driving the push plate to move vertically, and the fragments of Codonopsis pilosula will move up with the push plate and re-enter the crushing bin from the discharge port. The high-pressure pump is started to suck the fragments at the bottom of the return bin that have not been filtered by the second filter plate through the suction pipe and discharge them into the crushing bin for secondary processing. Since the second filter plate is movably connected to the main body of the extraction equipment, it can be taken out and cleaned at any time;

[0024] Step S25, when the material is returned, some liquid mixture will enter the return bin with the broken pieces, and enter the feed pipe after being filtered through the second filter plate. The third motor is started to drive the drive shaft to rotate, so that the auger blades rotate to loosen the mixture from the return bin to the discharge port, and the movable screw is rotated to open the second baffle plate, and the liquid filtered through the first filter plate and the liquid transported by the feed pipe are discharged from the discharge port and collected in containers such as a recovery box;

[0025] Step S3, ethanol precipitation: adding ethanol to the cooled concentrated solution until the concentration of the alcohol precipitation is 70%-90%, standing, centrifuging, and obtaining an alcohol precipitate;

[0026] Step S4, dehydration: washing the alcohol precipitate with anhydrous ethanol, acetone and ether in sequence;

[0027] Step S5, drying: vacuum drying the washed alcohol precipitate to obtain a yellow-white powder.

[0028] Beneficial effects of the present invention:

[0029] The present invention provides a preparation process and method of codonopsis pilosula polysaccharide extracted from codonopsis pilosula. The crankshaft is driven to rotate by starting a first motor. Since the crankshaft is movably pin-connected to a movable push rod, the movable push rod is driven to move back and forth left and right when the crankshaft rotates, thereby pushing an extrusion block to move back and forth left and right along a supporting slide rod under the action of a sliding sleeve block. The codonopsis pilosula enters a crushing bin from a feed inlet, is repeatedly impacted by the extrusion block, and is crushed. The juice inside the codonopsis pilosula is extracted and falls from a through hole.

[0030] The present invention provides a preparation process and method of codonopsis polysaccharide extracted from codonopsis pilosula. The polysaccharide extract is added into a stirring chamber, and the crushed codonopsis pilosula pieces and juice fall into the stirring chamber together. The crankshaft rotates to drive the first bevel gear to rotate. Under the meshing action of the gears, the second bevel gear drives the fixed shaft to rotate, thereby rotating the first sprocket. Since the first sprocket is chain-driven by the first chain and the second sprocket, the first sprocket pushes the first chain to move under the action of friction, driving the second sprocket to rotate synchronously, so that the stirring shaft drives the stirring blade to rotate, and the polysaccharide extract and the codonopsis pilosula juice are stirred and mixed, thereby accelerating the reaction.

[0031] The present invention provides a preparation process and method of codonopsis polysaccharide extracted from codonopsis pilosula. The mixture after stirring is filtered through a first filter plate. After filtering, the hydraulic cylinder is started to pull the first baffle plate upward, and the stirring shaft rotates to drive the third sprocket to rotate. Since the third sprocket is chain-driven by the second chain and the fourth sprocket, the third sprocket pushes the second chain to move under the action of friction, driving the fourth sprocket to rotate, thereby rotating the eccentric wheel. Since the first filter plate is movably pin-connected with the main body of the extraction device, the first filter plate vibrates, and the broken pieces and residues on it enter the return material bin from the return material port.

[0032] The present invention provides a preparation process and method of codonopsis polysaccharide extracted from codonopsis pilosula. The second motor is started to drive the second conveying roller to rotate. Since the second conveying roller is chain-driven with the first conveying roller through the conveyor belt, the second conveying roller pushes the conveyor belt to move under the action of friction, so that the first conveying roller rotates synchronously, thereby driving a push plate to move vertically. The codonopsis pilosula fragments will move up with the push plate and re-enter the crushing bin from the discharge port. The high-pressure pump is started to suck the fragments at the bottom of the return bin that have not been filtered by the second filter plate through the suction pipe and discharge them into the crushing bin for secondary processing. Since the second filter plate is movably connected to the main body of the extraction equipment, it can be taken out and cleaned at any time. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] Step S1, dust removal and cleaning: Rinse the medicinal material Codonopsis pilosula with clean water and set aside;

[0053] Step S2, crushing and filtering:

[0054] Step S21, the first motor 9 is started to drive the crankshaft 8 to rotate. Since the crankshaft 8 is movably pin-connected with the movable push rod 7, the crankshaft 8 drives the movable push rod 7 to reciprocate left and right, thereby pushing the extrusion block 4 to reciprocate left and right along the support slide rod 6 under the action of the sliding sleeve block 5. The codonopsis enters the crushing chamber 3 from the feed inlet 2, is repeatedly hit by the extrusion block 4, and is crushed, and the juice inside is extracted and falls from the through hole 10;

[0055] Step S22, adding polysaccharide extract into the stirring chamber 11, the crushed Codonopsis pilosula pieces and juice fall into the stirring chamber 11 together, the crankshaft 8 rotates to drive the first bevel gear 12 to rotate, and under the meshing action of the gears, the second bevel gear 13 drives the fixed shaft to rotate, so that the first sprocket 14 rotates, because the first sprocket 14 is chain-driven by the first chain 15 and the second sprocket 16, the first sprocket 14 pushes the first chain 15 to move under the action of friction, driving the second sprocket 16 to rotate synchronously, so that the stirring shaft 17 drives the stirring blade 18 to rotate, and the polysaccharide extract and the Codonopsis pilosula juice are stirred and mixed, thereby accelerating the reaction;

[0056] Step S23, the mixture after stirring is filtered through the first filter plate 23. After filtering, the hydraulic cylinder 26 starts to pull the first baffle plate 25 upward, and the stirring shaft 17 rotates to drive the third sprocket 19 to rotate. Since the third sprocket 19 is chain-driven by the second chain 20 and the fourth sprocket 21, the third sprocket 19 pushes the second chain 20 to move under the action of friction, driving the fourth sprocket 21 to rotate, thereby rotating the eccentric wheel 22. Since the first filter plate 23 is movably pin-connected with the extraction equipment body 1, the first filter plate 23 vibrates, and the broken pieces and residues on it enter the return bin 27 from the return port 24;

[0057] Step S23, the second motor 31 is started to drive the second conveying roller 30 to rotate. Since the second conveying roller 30 is chain-driven with the first conveying roller 28 through the conveyor belt 29, the second conveying roller 30 pushes the conveyor belt 29 to move under the action of friction, so that the first conveying roller 28 rotates synchronously, thereby driving the push plate 32 to move vertically, and the fragments of Codonopsis pilosula will move up with the push plate 32 and re-enter the crushing bin from the discharge port 36.

Since the second filter plate 33 is movably connected to the extraction equipment body 1, it can be taken out and cleaned at any time;

[0058] Step S24, when the material is recycled, some liquid mixture will enter the recycling bin 27 with the broken pieces, and enter the feeding pipe 37 after being filtered through the second filter plate 33. The third motor 39 is started to drive the driving shaft 38 to rotate, so that the auger blade 40 rotates, and the mixture is released from the recycling bin 27 to the discharge port 41. The movable screw 43 is rotated to open the second baffle 42, and the liquid filtered by the first filter plate 23 and the liquid transported by the feeding pipe 37 are discharged from the discharge port 41 and collected in a container such as a recycling box.

[0059] Step S3, ethanol precipitation: adding ethanol to the cooled concentrated solution until the concentration of the alcohol precipitation is 70%-90%, standing, centrifuging, and obtaining an alcohol precipitate;

[0060] Step S4, dehydration: washing the alcohol precipitate with anhydrous ethanol, acetone and ether in sequence;

10. A method for extracting codonopsis polysaccharide from codonopsis pilosula, characterized in that: The following steps are involved: Step S1, dust removal and cleaning: Rinse the medicinal material Codonopsis pilosula with clean water and set aside; Step S2, crushing and filtering: Step S21, the first motor (9) is started to drive the crankshaft (8) to rotate. Since the crankshaft (8) is movably pin-connected to the movable push rod (7), the crankshaft (8) drives the movable push rod (7) to move back and forth left and right, thereby pushing the extrusion block (4) to move back and forth left and right along the support slide rod (6) under the action of the sliding sleeve block (5). The codonopsis pilosula enters the crushing chamber (3) from the feed inlet (2), is repeatedly impacted by the extrusion block (4), and is crushed, and the juice inside is extracted and falls from the through hole (10); Step S22, adding polysaccharide extract into the stirring chamber (11), the crushed Codonopsis pilosula pieces and juice fall into the stirring chamber (11), the crankshaft (8) rotates to drive the first bevel gear 12 to rotate, and under the meshing action of the gears, the second bevel gear (13) drives the fixed shaft to rotate, thereby rotating the first sprocket (14), and because the first sprocket (14) is chain-driven with the second sprocket (16) through the first chain (15), the first sprocket (14) pushes the first chain (15) to move under the action of friction, driving the second sprocket (16) to rotate synchronously, so that the stirring shaft (17) drives the stirring blade (18) to rotate, and the polysaccharide extract and the Codonopsis pilosula juice are stirred and mixed, thereby accelerating the reaction; Step S23, the mixture after stirring is filtered through the first filter plate (23). After filtering is completed, the hydraulic cylinder (26) is started to pull the first baffle plate (25) upward, and the stirring shaft (17) rotates to drive the third sprocket (19) to rotate. Since the third sprocket (19) is chain-driven by the second chain (20) and the fourth sprocket (21), the third sprocket (19) pushes the second chain (20) to move under the action of friction, driving the fourth sprocket (21) to rotate, thereby rotating the eccentric wheel (22). Since the first filter plate (23) is movably pin-connected with the extraction device body (1), the first filter plate (23) vibrates, and the broken pieces and residues thereon enter the return material bin (27) from the return material port (24); Step S23, the second motor (31) is started to drive the second conveying roller (30) to rotate. Since the second conveying roller (30) is chain-driven with the first conveying roller (28) through the conveyor belt (29), the second conveying roller (30) pushes the conveyor belt (29) to move under the action of friction, so that the first conveying roller (28) rotates synchronously, thereby driving the push plate (32) to move vertically. The fragments of Codonopsis pilosula will move upward with the push plate (32) and re-enter the crushing bin from the discharge port (36). The high-pressure pump (35) is started to suck the fragments at the bottom of the return bin (27) that have not been filtered by the second filter plate (33) through the suction pipe (34) and discharge them into the crushing bin for secondary processing. Since the second filter plate (33) is movably connected to the extraction equipment body (1), it can be taken out and cleaned at any time. Step S24, when the material is recycled, some liquid mixture will enter the recycling bin (27) along with the broken pieces, and will be filtered through the second filter plate (33) and enter the feeding pipe (37). The third motor (39) is started to drive the driving shaft (38) to rotate, thereby rotating the auger blade (40) to loosen the mixture from the recycling bin (27) into the discharge port (41), and the movable screw (43) is rotated to open the second baffle (42), and the liquid filtered through the first filter plate (23) and the liquid transported by the feeding pipe (37) are discharged from the discharge port (41) and collected in a container such as a recycling box; Step S3, ethanol precipitation: adding ethanol to the cooled concentrated solution until the concentration of the alcohol precipitation is 70%-90%, standing, centrifuging, and obtaining an alcohol precipitate; Step S4, dehydration: washing the alcohol precipitate with anhydrous ethanol, acetone and ether in sequence; Step S5, drying: vacuum drying the washed alcohol precipitate to obtain a yellow-white powder.
