Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of starch processing and separation, in particular to a straight-chain starch separation device. BACKGROUND

[0002] Starch is composed of two main components: amylose and amylopectin. Amylose is linearly connected by alpha-1, 4 glycosidic bonds, while amylopectin contains alpha-1, 6 glycosidic bonds in addition to alpha-1, 4 glycosidic bonds, forming a branched structure. The ratio of amylose to amylopectin affects the properties of starch, such as its pasting characteristics, viscosity, and digestion speed.

[0003] Amylose, as a natural high-molecular polysaccharide, has important application value in the food industry (such as functional food, low GI products), biomaterials (degradable films, drug carriers), and chemical industries due to its unique linear molecular structure and anti-digestion properties. Preparing amylose usually requires separating it from amylopectin, and the differences in physicochemical properties (such as solubility, crystallinity, and complexing ability) between amylose and amylopectin are the basis for separation.

[0004] Butanol precipitation crystallization method is one of the standard methods for preparing amylose due to its good separation effect, high separation purity, and reliable principle. The linear structure of amylose can form a tight, water-insoluble helical inclusion complex with polar organic molecules containing hydrophobic groups such as butanol and pentanol through hydrophobic interaction and hydrogen bonding. Amylopectin, due to its highly branched structure, cannot form such regular and ordered crystalline complexes and is usually left in the solution. The key to separating and preparing amylose by butanol precipitation crystallization method is to completely gelatinize and dissolve the starch to avoid particle residues or molecular aggregation. However, starch has strong water absorption, so there are inevitable clumps in the starch raw material, and the clump parts cannot be fully dispersed even after stirring during the gelatinization process, which leads to incomplete gelatinization and dissolution, thereby affecting the yield of amylose. Meanwhile, the butanol precipitation crystallization method has many operation steps and is time-consuming, requiring gelatinization and dispersion, slow cooling crystallization, filtration, washing, and drying, which is very time-consuming and limits large-scale production.

[0078] An auger conveyor 300 is installed on the operation platform 100;

[0079] A breaking and discharging mechanism 400 is arranged on the top of the auger conveyor 300, through the breaking and discharging mechanism 400, the starch raw material is continuously discharged into the auger conveyor 300 while preventing the caked starch raw material from directly entering the auger conveyor 300, and the caked starch raw material is concentrated and broken to be scattered;

[0080] A premixing feeding mechanism 500 is arranged on the operation platform 100 and connected to the reaction kettle 200, the premixing feeding mechanism 500 feeds the starch raw material into the reaction kettle 200 and forms a fluid mixture in advance during the conveying process;

[0081] The auger conveyor 300 is connected to the premixing feeding mechanism 500, which forms a complete conveying chain from the breaking and discharging mechanism 400 to the reaction kettle 200, the amylose separation device adds two processing procedures formed by the breaking and discharging mechanism 400 and the premixing feeding mechanism 500 during the normal process of feeding the starch raw material into the reaction kettle 200, through the breaking and discharging mechanism 400, the starch raw material can be identified for eligibility, the dispersed starch raw material without caking is continuously supplied to the auger conveyor 300 as a feeding source, while the starch raw material with caking is blocked, and the caked starch raw material can be concentrated and ground to break the caked part and restore the loose nature of the starch raw material; through the premixing feeding mechanism 500, the continuously conveyed starch raw material can be uniformly mixed into a mixture required for separation during the conveying process, and the mixture can be heated at the same time to increase the temperature and achieve preheating;

[0082] The straight starch separation device effectively solves the problem that the caking of the starch raw material affects the final separation yield, ensures that the starch raw material used can be fully gelatinized and dissolved, prevents the occurrence of particle residues or molecular aggregation during the separation process, ensures the preparation yield, avoids waste of the starch raw material, and pre-completes the generation and heating of the mixture during the raw material conveying process, thereby effectively reducing the time required for the corresponding operation steps in the reaction kettle 200, shortening the time consumption of the whole process of separating straight starch as much as possible, and further improving the production efficiency.

[0083] Optionally, the breaking and discharging mechanism 400 comprises:

[0084] A hopper 410 is installed directly above the hopper of the auger conveyor 300, the inner bottom surface of the hopper 410 is inclined, and an outlet is formed at the lowest part of the hopper 410, and the hopper 410 is used to store starch raw materials;

[0085] A groove-shaped side plate 420 is connected at the outlet and extends downward, and the groove-shaped side plate 420 is close to the hopper of the auger conveyor 300;

[0086] A side panel 430 is movably buckled in the groove-shaped side plate 420, the side panel 430 is close to the groove-shaped side plate 420, and the gap between the side panel 430 and the groove-shaped side plate 420 decreases from top to bottom, so that the caked starch can enter between the side panel 430 and the groove-shaped side plate 420, but as the starch moves downward, the gap between the side panel 430 and the groove-shaped side plate 420 becomes smaller and smaller, and finally the starch is stuck;

[0087] A rubber strip 440 is connected between the top of the side panel 430 and the hopper 410, and the rubber strip 440, the side panel 430 and the groove-shaped side plate 420 form a complete discharging channel;

[0088] Two lifting plates 450 are installed at the bottom of the hopper 410;

[0089] Two electric push rods 460 are vertically installed on the two lifting plates 450, respectively;

[0090] Two telescopic connecting column bodies 470 are connected at one end with the output ends of the two electric push rods 460, respectively, and the other end of the two telescopic connecting column bodies 470 is towards the side panel 430;

[0091] Two outer octagonal connectors 480, two said outer octagonal connectors 480 are connected between the other end of two said telescopic connecting columns 470 and said side panel 430 respectively, two said outer octagonal connectors 480 are located at both ends of said side panel 430 respectively, the interval between the trough-shaped side panel 420 and the side panel 430 is controlled well before separation, that is, in the initial state, so that the normally dispersed starch raw materials in the silo 410 can smoothly fall into the hopper of the auger conveyor 300 below through the gap between the trough-shaped side panel 420 and the side panel 430, ensuring continuous feeding, while the starch lumps that have already appeared agglomeration phenomenon cannot pass smoothly and are stuck between the trough-shaped side panel 420 and the side panel 430, blocking the starch raw materials with agglomeration, and starting two electric push rods 460 during the separation process or when the starch lumps are blocked due to too many blocked starch lumps, the side panel 430 is pushed and pulled up and down along the trough-shaped side panel 420 through the transmission of two telescopic connecting columns 470 and two outer octagonal connectors 480, the output end of two electric push rods 460, because the gap between the lower part of the side panel 430 and the trough-shaped side panel 420 is smaller than the gap between the upper part of the side panel 430 and the trough-shaped side panel 420, so that the side panel 430 is used to crush the stuck starch lumps during the upward movement of the side panel 430, forcibly crushing the starch lumps, restoring the looseness of the starch raw materials, so that they can successfully fall into the hopper of the auger conveyor 300, thereby effectively solving the problem of affecting the subsequent starch raw materials gelatinization and dissolution due to the existence of agglomeration of starch raw materials, preventing the occurrence of particle residues or molecular aggregation during the separation process, ensuring the yield and avoiding the waste of starch raw materials; the downward movement of the side panel 430 promotes the downward sliding of the starch raw materials, avoiding the blockage of the starch raw materials between the trough-shaped side panel 420 and the side panel 430; the use of rubber strips 440 makes the side panel 430 and the silo 410 become flexible connection, the rubber strips 440 are stretched when the side panel 430 moves up and down, ensuring that the side panel 430 moves normally while maintaining the integrity of the side panel 430 and the silo 410, to prevent the gap between the two from causing the starch in the silo 410 to leak when the side panel 430 moves.

[0092] Optionally, the dispersing and discharging mechanism 400 further comprises:

[0093] A right-angle plate 490 connected to the side panel 430, a hole is opened in the right-angle plate 490;

[0094] A spring 491, one end of the spring 491 is connected to the right-angle plate 490, and the other end is connected to the middle of the side panel 430;

[0095] A first motor 492 installed on the back of the right-angle plate 490;

[0096] A spool 493 is installed on the output shaft of the first motor 492;

[0097] A cable 494 is wound on the spool 493 at one end and connected to the side panel 430 through the hole on the right angle plate 490 and the spring 491 at the other end;

[0098] Two side connecting wing plates 495 are connected between the right angle plate 490 and the tail of the two telescopic connecting columns 470 respectively. The telescopic connecting column 470 is composed of two columns with different diameters. The thinner column is inserted into the thicker column with a certain friction force. When the two electric push rods 460 generate vertical force to push and pull the side panel 430 up and down, the telescopic connecting column 470 remains stationary;

[0099] Under normal circumstances, the spring 491 is in a compressed state. Start the two electric push rods 460 at the same time and start the first motor 492 to drive the spool 493 to rotate, loosen the cable 494 wound on the spool 493 a little, and the spring 491 loses the corresponding amount of restriction and rebounds accordingly to lengthen the two telescopic connecting columns 470, thereby pushing the side panel 430 forward and making it closer to the groove-shaped side plate 420. At the same time, the side panel 430 is also pressed more tightly against the starch block, thereby crushing the starch block under pressure, further improving the crushing effect on the starch block, preventing incomplete crushing, and preventing the starch block from being crushed to the side panel 430 when the side panel 430 moves upward.

[0100] When the side panel 430 moves downward, the first motor 492 is driven in reverse to rewind the cable 494, so that the spring 491 is compressed again, and at the same time, the two telescopic connecting columns 470 are retracted, so that the side panel 430 is reset;

[0101] When the starch adheres to the groove-shaped side plate 420 after crushing, causing blockage or poor discharge, the first motor 492 is driven to quickly loosen the cable 494, causing the spring 491 to rapidly rebound, causing the side panel 430 to quickly hit the groove-shaped side plate 420, and cooperating with the side panel 430 to move up and down to clean the adhering starch, keeping the discharge channel unobstructed and preventing affecting the separation process.

[0102] Optionally, the premix feeding mechanism 500 comprises:

[0103] A reaction cylinder 510 is provided on the operation platform 100;

[0106] A first connecting pipe 540, one end of the first connecting pipe 540 is connected to the discharge port of the auger conveyor 300, and the other end penetrates the hollow top cover 520 and enters the reaction cylinder 510;

[0107] Two tank bodies 550, the two tank bodies 550 are arranged side by side on the operation platform 100, and the two tank bodies 550 respectively store water and butanol, and the butanol precipitation crystallization method needs to completely gelatinize and disperse the starch in water to form a transparent starch paste, and a sufficient amount of n-butanol is added;

[0108] Two second connecting pipes 560, one end of the two second connecting pipes 560 is connected to the hollow top cover 520, and the other end is respectively connected to a submersible pump in the two tank bodies 550;

[0109] A rotating member 570, the rotating member 570 is placed on the inner bottom surface of the reaction cylinder 510;

[0110] A second motor 580, the second motor 580 is installed at the bottom of the reaction cylinder 510, and the output shaft of the second motor 580 penetrates into the reaction cylinder 510 and is connected to the rotating member 570 in an upward direction;

[0111] A plurality of blades 590, the plurality of blades 590 are located in the reaction cylinder 510 and are arranged on the rotating member 570;

[0113] A delivery pump 592, the delivery pump 592 is arranged on the operation platform 100, and the other end of the two third connecting pipes 591 is connected to the inlet of the delivery pump 592 through a main connecting pipe;

[0114] The main pipe 593 is connected to the outlet of the conveying pump 592 at one end and opens into the reaction kettle 200 at the other end. The auger conveyor 300 continuously conveys the starch raw material falling from the silo 410 into the reaction cylinder 510 through the first connecting pipe 540, and simultaneously starts the submersible pumps in the two tanks 550 to convey water and butanol into the hollow top cover 520 through the two second connecting pipes 560, and then makes the mixture of water and butanol flow into the reaction cylinder 510 through the several discharge pipes 530, and simultaneously starts the second motor 580 to drive the rotating part 570 to rotate, so that the several blades 590 stir in the reaction cylinder 510, so that the starch raw material is mixed with water and butanol as soon as it enters the reaction cylinder 510, and forms a mixture under the stirring of the several blades 590, and then the mixture is pumped out of the reaction cylinder 510 through the two third connecting pipes 591 by the conveying pump 592, and is sent into the reaction kettle 200 through the main pipe 593, so that the mixture required for separation is formed during the conveying of the starch raw material, so that the subsequent mixing of the starch raw material, water and n-butanol in the reaction kettle 200 is not required or only slight mixing is required, effectively reducing the time occupied by the separate mixing step in the separation process, thereby shortening the time consumption of the overall process of separating amylose, improving the production efficiency, and pre-mixing and feeding mechanism 500 disperses the starch raw material as it enters, so that the starch raw material is always subjected to gelatinization in small amounts, avoiding the situation that a large amount of starch raw material is directly added to the reaction kettle 200 and then water and n-butanol are added for gelatinization, which causes the starch raw material to be gelatinized on the outside and still dry on the inside, so that the starch raw material is completely gelatinized and dispersed, and all starch molecules are fully dissolved, thereby effectively ensuring the success and yield of the separation.

[0115] Optionally, the rotating part 570 covers the inner bottom surface of the reaction cylinder 510;

[0116] The rotating part 570 is provided with two through holes 571, and the two through holes 571 on the rotating part 570 can intermittently coincide with the two third connecting pipes 591 during the rotation of the rotating part 570. During the separation process, the mixture in the reaction cylinder 510 is only pumped out through the two third connecting pipes 591 when the two through holes 571 on the rotating part 570 coincide with the two third connecting pipes 591, so as to realize intermittent pumping of the mixture, ensure that the starch raw material has a certain time to be stirred with water and n-butanol by the several blades 590 in the reaction cylinder 510, and receive gelatinization and mixing, rather than being quickly pumped out after entering the reaction cylinder 510, prevent the preliminary gelatinized product from being pumped out, and ensure the full dissolution of the starch molecules.

[0117] Optionally, the rotating part 570 is provided with several protruding columns 572;

[0118] A plurality of said blades 590 are respectively sleeved on a plurality of said protruding column bodies 572, so that a plurality of blades 590 can rotate relative to each other, so that when a plurality of blades 590 are stirred, they can each rotate adaptively when encountering resistance, and the rotation direction of a plurality of blades 590 may be consistent at times and opposite at times, thereby forming an unsteady and variable stirring force in the reaction cylinder 510 through a plurality of blades 590, further promoting the mixing of starch raw materials with water and n-butanol, and further ensuring the sufficient dissolution of starch molecules.

[0119] Optionally, a plurality of said protruding column bodies 572 have cavities, and electric heating rods 573 are inserted into the cavities;

[0120] A plurality of said electric heating rods 573 are connected to an external power source through wires. Since the solubility of amylose in hot water is relatively high, and the molecular weight of amylopectin is large and easy to entangle, the solubility is relatively low, so the mixture usually needs to be heated to 70-80 degrees Celsius during separation. When a plurality of blades 590 begin to stir, the external power source is turned on, the electric heating rods 573 are powered on to start heating, and the heat is transferred to the mixture through a plurality of protruding column bodies 572 and a plurality of blades 590, so that the mixture is gradually heated, thereby achieving the preheating effect during conveying, so that the mixture enters the reaction kettle 200 at a certain temperature, thereby effectively reducing the time required for the subsequent heating step, as much as possible to shorten the time consumption of the whole separation process, further improve the production efficiency, and better adapt to large-scale production.

[0121] A plurality of protruding column bodies 572 and a plurality of blades 590 are made of materials with good heat transfer performance such as copper, so that the heat generated by the electric heating rods 573 can be quickly transferred to the mixture, and the heating effect on the mixture is guaranteed as much as possible.

[0122] Optionally, a plurality of rubber short columns 496 are arranged between the side panel 430 and the groove-shaped side panel 420.

[0123] A plurality of said rubber short columns 496 are arranged in a cross arrangement, and the rubber short columns 496 can be arbitrarily squeezed and stretched, thereby forming an additional barrier between the side panel 430 and the groove-shaped side panel 420 without hindering the normal movement of the side panel 430, and ensuring that all starch raw materials with lumps are blocked, so as to prevent starch lumps from leaking and participating in the subsequent separation process and affecting the normal separation of amylose.

[0124] Optionally, the outermost a plurality of said discharge pipes 530 are rectangular and are arranged obliquely outward, and a plurality of discharge pipes 530 are directed toward the inner wall of the reaction cylinder 510, so that the discharged water and n-butanol mixture can flush the inner wall of the reaction cylinder 510 at the same time, preventing starch paste from accumulating on the inner wall of the reaction cylinder 510 for a long time and causing cleaning difficulties and other negative effects.

[0125] Optionally, the inner wall of the main delivery pipe 593 is engraved with multiple helical patterns, and the directions of the patterns are alternately changed in sequence, that is, the helical patterns on the inner wall of the main delivery pipe 593 are positive in one section and negative in another section, and the process is repeated, so that the mixture is guided to repeatedly flow in positive and negative directions in a helical manner during the process of entering the reaction kettle 200 through the main delivery pipe 593, thereby mixing the mixture again and further ensuring the sufficient dissolution of the starch raw material.

[0126] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Various modifications and changes can be made by those skilled in the art based on the spirit and principles of the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
