Description

Technical Field

[0001] This invention relates to the field of starch processing and separation technology, and more specifically, to a device for separating amylose. Background Technology

[0002] Starch is composed of two main types of components: amylose and amylopectin. Amylose is formed by glucose molecules linearly linked by α-1,4 glycosidic bonds, while amylopectin contains both α-1,4 and α-1,6 glycosidic bonds, forming a branched structure. The ratio of amylose to amylopectin affects the properties of starch, such as its gelatinization characteristics, viscosity, and digestibility.

[0003] Amylose, as a natural high-molecular-weight polysaccharide, has significant application value in the food industry (such as functional foods and low-GI products), biomaterials (biodegradable films, drug carriers), and chemical industry due to its unique linear molecular structure and resistance to digestion. The preparation of amylose usually requires its separation from amylopectin, and the differences in their physicochemical properties (such as solubility, crystallinity, and complexing ability) are fundamental to achieving this separation.

[0004] Butanol precipitation crystallization is a standard method for preparing amylose due to its good separation effect, high purity, and reliable principle. The linear structure of amylose can form tight, water-insoluble helical inclusion complexes with polar organic molecules containing hydrophobic groups, such as butanol and pentanol, through hydrophobic interactions and hydrogen bonds. Amylopectin, due to its highly branched structure, cannot form such regular and ordered crystalline complexes and usually remains in solution. The key to separating and preparing amylose using butanol precipitation crystallization is the complete gelatinization and dissolution of the starch to avoid particle residue or molecular aggregation. However, starch is highly hygroscopic, so clumping is inevitable in the starch raw material. Even with stirring during gelatinization, the clumped areas cannot be fully dispersed, leading to incomplete gelatinization and dissolution. This prevents the successful separation of amylose from these areas, thus affecting the yield. Furthermore, the butanol precipitation crystallization method involves numerous and time-consuming steps, requiring sequential gelatinization and dispersion, slow cooling and crystallization, filtration, washing, and drying, which is very time-consuming and limits large-scale production. Summary of the Invention

[0009] Furthermore, the premixed feeding mechanism includes: A reaction chamber, which is mounted on the operating platform; A hollow top cover is installed on top of the reaction cylinder; A plurality of discharge pipes are connected to the hollow top cover and located inside the reaction cylinder. The plurality of discharge pipes are arranged in a multi-layered circumferential shape from the inside out. The first connecting pipe has one end connected to the discharge port of the screw conveyor and the other end passing through the hollow top cover into the reaction cylinder; Two tanks are arranged side by side on the operating platform, and the two tanks respectively store water and butanol; Two second connecting pipes, one end of which is connected to the hollow top cover, and the other end is connected to the submersible pumps in the two tanks respectively; A rotating component, which is placed on the inner bottom surface of the reaction cylinder; A second motor is installed at the bottom of the reaction cylinder, and the output axis of the second motor passes through the reaction cylinder and is connected to the rotating component.

[0010] Furthermore, the rotating component covers the inner bottom surface of the reaction cylinder; The rotating component has two through holes, and during the rotation of the rotating component, the two through holes on the rotating component can intermittently coincide with the two third connecting pipes.

[0011] Furthermore, the rotating component has several protruding pillars; Several blades are respectively rotatably mounted on several protruding columns.

[0012] Furthermore, several of the protruding pillars have cavities inside, and heating rods are inserted into the cavities. Several of the heating rods are connected to an external power source via wires.

The breaking and feeding mechanism can identify the quality of the starch raw materials, continuously supplying dispersed, non-clumped starch raw materials to the auger conveyor as the source of feed, while blocking starch raw materials with clumps and concentrating on grinding the clumped starch raw materials, thereby breaking up the clumps and restoring the looseness of the starch raw materials.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0021] To address the issue of starch raw material agglomeration affecting the separation process and yield, and to improve the time-consuming nature of the separation process, thereby increasing production efficiency, such as... Figure 1-15 As shown, a linear starch separation device includes: Operating platform 100, which is arranged on the ground, allows on-site operators to board the operating platform 100 during the separation process to perform steps that require manual intervention or observation. The reaction vessel 200 is embedded in the side of the operating platform 100, and the reaction vessel 200 provides a reaction space for the separation of amylose. Screw conveyor 300, which is installed on the operating platform 100; The breaking and feeding mechanism 400 is located at the top of the auger conveyor 300. The breaking and feeding mechanism 400 continuously feeds starch raw materials into the auger conveyor 300 while preventing clumped starch raw materials from directly entering the auger conveyor 300, and concentrates and breaks up the clumped starch raw materials to disperse them. A premixed feeding mechanism 500 is disposed on the operating platform 100 and enters the reactor 200. The premixed feeding mechanism 500 feeds starch raw materials into the reactor 200 and precisely forms a fluid mixture in advance during the conveying process. The auger conveyor 300 leads into the premixing conveying mechanism 500, forming a complete conveying chain from the breaking and feeding mechanism 400 to the reactor 200. This linear starch separation device adds two processing steps—the breaking and feeding mechanism 400 and the premixing conveying mechanism 500—to the normal process of feeding starch raw materials into the reactor 200. The breaking and feeding mechanism 400 can identify the quality of the starch raw materials, continuously supplying dispersed, non-agglomerated starch raw materials to the auger conveyor 300 as the source of feed, while blocking agglomerated starch raw materials and centrally grinding the agglomerated starch raw materials to break up the agglomerated parts and restore the looseness of the starch raw materials. The premixing conveying mechanism 500 can specifically and uniformly mix the continuously fed starch raw materials into the mixture required for separation during the process of conveying the starch raw materials into the reactor 200, and can simultaneously heat the mixture to raise its temperature for preheating. This amylose separation device effectively solves the problem of starch raw material agglomeration affecting the final separation yield. It ensures that all starch raw materials are fully gelatinized and dissolved, preventing particle residue or molecular aggregation during separation, guaranteeing production output, avoiding waste of starch raw materials, and utilizing the raw material transportation process to pre-generate and heat the mixture, thereby effectively reducing the time required for corresponding operation steps in the reactor 200, shortening the overall time consumption of the amylose separation process as much as possible, and thus improving production efficiency.

[0022] Optionally, the crushing and feeding mechanism 400 includes: The hopper 410 is installed directly above the hopper of the screw conveyor 300. The inner bottom surface of the hopper 410 is inclined and an outlet is provided at the lowest point of the hopper 410. The hopper 410 is used to store starch raw materials. A trough-shaped side plate 420 is connected to the outlet and extends downward, the trough-shaped side plate 420 being close to the hopper of the auger conveyor 300; Side panel 430 is attached to and movably fastened inside the grooved side plate 420. The side panel 430 is close to the grooved side plate 420. The gap between the side panel 430 and the grooved side plate 420 decreases from top to bottom, allowing the clump of starch to enter between the side panel 430 and the grooved side plate 420. However, as the starch clump moves downward, the gap between the side panel 430 and the grooved side plate 420 becomes smaller and smaller, eventually causing the starch clump to get stuck. Adhesive strip 440 connects the top of the side panel 430 and the hopper 410, and the adhesive strip 440, the side panel 430 and the grooved side panel 420 form a complete material discharge channel; Two lifting platforms 450 are installed at the bottom of the hopper 410; Two electric push rods 460 are respectively vertically mounted on the two lifting plates 450; Two telescopic connecting columns 470, one end of each of the two telescopic connecting columns 470 is connected to the output end of the two electric push rods 460 respectively, and the other end of each of the two telescopic connecting columns 470 faces the side panel 430. Two outward-pointing connectors 480 are respectively connected between the other ends of the two telescopic connecting columns 470 and the side panel 430. The two outward-pointing connectors 480 are located at both ends of the side panel 430. Before separation, i.e. in the initial state, the distance between the trough-shaped side plate 420 and the side panel 430 is controlled so that the normally dispersed starch raw material in the hopper 410 can smoothly fall into the auger conveyor below through the gap between the trough-shaped side plate 420 and the side panel 430. In the hopper of machine 300, a continuous supply of material is ensured, preventing starch clumps that have already formed from passing through smoothly. Instead, these clumps become stuck between the trough-shaped side plate 420 and the side panel 430, thus blocking the starch raw material with clumps. During the separation process, or when there are too many starch clumps causing blockage, two electric push rods 460 are activated periodically. Through the extension and retraction of the output ends of the two electric push rods 460 and the transmission of the two telescopic connecting columns 470 and the two outward-pointing connecting parts 480, the side panel 430 is moved up and down against the trough-shaped side plate 420. The pushing and pulling action, because the gap between the lower part of the side panel 430 and the trough-shaped side plate 420 is smaller than the gap between the upper part of the side panel 430 and the trough-shaped side plate 420, utilizes the upward movement of the side panel 430 to crush the stuck starch blocks, forcibly breaking them down and restoring the looseness of the starch raw material. This allows it to successfully fall into the hopper of the auger conveyor 300, effectively solving the problem of starch raw material agglomeration affecting subsequent starch gelatinization and dissolution, preventing particle residue or molecular aggregation during separation, ensuring yield, and avoiding... This prevents the waste of starch raw materials; during the downward movement of the side panel 430, the starch raw materials are facilitated to slide down, avoiding blockage between the trough-shaped side panel 420 and the side panel 430; the adhesive strip 440 is used to make a flexible connection between the side panel 430 and the hopper 410. The adhesive strip 440 is stretched when the side panel 430 moves up and down, ensuring that it does not hinder the normal movement of the side panel 430 while maintaining the integrity of the side panel 430 and the hopper 410, so as to prevent the starch in the hopper 410 from leaking due to gaps between the two when the side panel 430 moves.

[0023] Optionally, the crushing and feeding mechanism 400 further includes: A right-angle plate 490 is connected to the side panel 430, and the right-angle plate 490 has holes. Spring 491, one end of which is connected to the right-angle plate 490, and the other end is connected to the center of the side panel 430; The first motor 492 is mounted on the back of the right-angle plate 490; The I-beam wheel 493 is mounted on the output shaft of the first motor 492; A cable 494, one end of which is wound on the I-beam 493 and the other end passes through a hole in the right-angle plate 490 and the spring 491 and is connected to the side panel 430. Two side connecting wing plates 495 are respectively connected between the two sides of the right angle plate 490 and the tail of the two telescopic connecting columns 470. The telescopic connecting column 470 is specifically formed by connecting two columns with different diameters. The thinner column slides into the thicker column, and there is a certain friction between the two. When the two electric push rods 460 generate a vertical force to push and pull the side panel 430 up and down, it remains stationary. Under normal conditions, spring 491 is in a compressed state. When the two electric push rods 460 are activated, the first motor 492 is also activated, which drives the I-beam wheel 493 to rotate. This loosens the cable 494 wound by the I-beam wheel 493 slightly, and spring 491 loses its corresponding amount of restraint and rebounds accordingly, stretching the two telescopic connecting columns 470. This pushes the side panel 430 forward, bringing it closer to the grooved side panel 420. At the same time, the side panel 430 squeezes the starch block more tightly, thus grinding the starch block under pressure. This further improves the crushing effect of the starch block, prevents incomplete crushing, and prevents the side panel 430 from failing to grind the starch block successfully when it moves upward. When the side panel 430 moves down, the first motor 492 reverses the drive to rewind the cable 494, causing the spring 491 to be compressed again. At the same time, the two telescopic connecting columns 470 retract, allowing the side panel 430 to reset. When starch adheres to the trough-shaped side plate 420 after grinding, causing blockage or poor material flow, the first motor 492 quickly releases the cable 494, causing the spring 491 to rebound rapidly. This causes the side plate 430 to quickly strike the trough-shaped side plate 420, and the side plate 430 moves up and down to clean off the adhered starch, keeping the material flow channel unobstructed and preventing it from affecting the separation process.

[0024] Optionally, the premixed feeding mechanism 500 includes: A reaction cylinder 510 is disposed on the operating platform 100; A hollow top cover 520 is installed on top of the reaction cylinder 510; A plurality of discharge pipes 530 are connected to the hollow top cover 520 and are located inside the reaction cylinder 510. The plurality of discharge pipes 530 are arranged in a multi-layered circumferential shape from the inside out. The first connecting pipe 540 has one end connected to the discharge port of the screw conveyor 300 and the other end passing through the hollow top cover 520 and into the reaction cylinder 510. Two tanks 550 are arranged side by side on the operating platform 100. The two tanks 550 respectively store water and butanol. The butanol precipitation crystallization method for separating amylose requires that the starch be completely gelatinized and dispersed in water to form a transparent starch paste, and sufficient n-butanol is added. Two second connecting pipes 560, one end of which is connected to the hollow top cover 520, and the other end is connected to the submersible pumps in the two tanks 550 respectively; Rotating component 570, which is placed on the inner bottom surface of the reaction cylinder 510; The second motor 580 is installed at the bottom of the reaction cylinder 510, and the output axis of the second motor 580 passes through the reaction cylinder 510 and is connected to the rotating component 570. A plurality of blades 590 are located inside the reaction cylinder 510 and are disposed on the rotating member 570; Two third connecting pipes 591, one end of which is connected to the reaction cylinder 510 from the bottom; A delivery pump 592 is installed on the operating platform 100, and the other ends of the two third pipes 591 are connected to the inlet of the delivery pump 592 through the main pipe. The main pipeline 593 is connected at one end to the outlet of the conveying pump 592 and at the other end to the reactor 200. An auger conveyor 300 continuously conveys starch raw material falling from the silo 410 into the reactor 510 through the first connecting pipe 540. Simultaneously, submersible pumps in the two tanks 550 are activated to convey water and butanol to the hollow top cover 520 through two second connecting pipes 560. The mixture of water and butanol then flows down into the reactor 510 through several discharge pipes 530. At the same time, the second motor 580 is activated, driving the rotating component 570 to rotate, causing several blades 590 to agitate within the reactor 510. This ensures that the starch raw material mixes with water and butanol as soon as it enters the reactor 510, forming a mixture under the agitation of the blades 590. The mixture is then pumped by the conveying pump 592 through two third connecting pipes 591. The starch is extracted from the reaction cylinder 510 and fed into the reaction vessel 200 via the main conveying pipe 593. This process forms the mixture required for separation during the transport of the starch raw material, eliminating the need for subsequent mixing of the starch raw material, water, and n-butanol in the reaction vessel 200, or requiring only slight mixing. This effectively reduces the time spent on separate mixing steps during separation, thereby shortening the overall time required for separating amylose and improving production efficiency. The premixed conveying mechanism 500 gelatinizes and disperses the starch raw material as it enters, ensuring that the starch raw material is always gelatinized in small amounts. This avoids the situation where a large amount of starch raw material is directly added to the reaction vessel 200 and then water and n-butanol are added for gelatinization, resulting in the starch raw material being gelatinized on the outside but still dry on the inside. This ensures that the starch raw material is completely gelatinized and dispersed, guaranteeing that all starch molecules are fully dissolved, thus effectively ensuring the success and yield of the separation.

[0025] Optionally, the rotating component 570 covers the inner bottom surface of the reaction cylinder 510; The rotating component 570 has two through holes 571. During the rotation of the rotating component 570, the two through holes 571 on the rotating component 570 can intermittently overlap with the two third connecting pipes 591. During the separation process, the mixture in the reaction cylinder 510 will only be drawn away through the two third connecting pipes 591 when the two through holes 571 on the rotating component 570 overlap with the two third connecting pipes 591. This intermittent pumping of the mixture ensures that the starch raw material is stirred with water and n-butanol by several blades 590 in the reaction cylinder 510 for a certain period of time, and undergoes gelatinization and mixing, rather than being quickly drawn away after entering the reaction cylinder 510. This prevents the starch from being drawn away after only forming a preliminary gelatinized product, and ensures the full dissolution of starch molecules.

[0026] Optionally, the rotating component 570 has a plurality of protruding pillars 572; Several blades 590 are respectively rotatably mounted on several protruding columns 572, so that the blades 590 can rotate relative to each other. When the blades 590 encounter resistance during stirring, they can rotate adaptively. The rotation direction of the blades 590 may be the same at times and opposite at times. Thus, the blades 590 form a non-fixed and variable stirring force in the reaction cylinder 510, which further promotes the mixing of starch raw materials with water and n-butanol, and further ensures the full dissolution of starch molecules.

[0027] Optionally, several of the protruding pillars 572 have cavities, and heating rods 573 are inserted into the cavities; Several heating rods 573 are connected to an external power source via wires. Since amylose has a high solubility in hot water, while amylopectin has a large molecular weight and is prone to entanglement, its solubility is relatively low. Therefore, the mixture usually needs to be heated to 70-80 degrees Celsius during separation. When several blades 590 start stirring, the external power source is turned on, so that several heating rods 573 are energized and start heating. The heat is transferred to the mixture through several protruding columns 572 and several blades 590, so that the mixture gradually heats up, thereby achieving a preheating effect during the conveying process. This allows the mixture to enter the reaction vessel 200 at a certain temperature, thereby effectively reducing the time required for subsequent heating steps, shortening the overall separation process time as much as possible, and further improving production efficiency to better adapt to large-scale production. The protruding pillars 572 and the blades 590 are made of materials with good heat transfer properties, such as copper, so that the heat generated by the heating rod 573 can be quickly transferred to the mixture, and the heating effect on the mixture can be guaranteed as much as possible.

[0028] Optionally, a plurality of rubber short posts 496 are disposed between the side panel 430 and the grooved side panel 420. The rubber short columns 496 are arranged in a cross pattern. The rubber short columns 496 can be squeezed and stretched at will. While not hindering the normal movement of the side panel 430, they form an additional barrier between the side panel 430 and the grooved side panel 420 to block starch blocks. This ensures that all starch raw materials with clumps are blocked, preventing starch blocks from leaking out and participating in the subsequent separation process, thus affecting the normal separation of amylose.

[0029] Optionally, the outermost discharge pipes 530 are rectangular and obliquely outward, with the discharge pipes 530 facing the inner wall of the reaction cylinder 510. This allows the discharged water and n-butanol mixture to simultaneously flush the inner wall of the reaction cylinder 510, preventing starch paste from accumulating on the inner wall of the reaction cylinder 510 and causing difficulties in cleaning and other negative effects.

[0030] Optionally, the inner wall of the main pipe 593 is engraved with multiple spiral patterns, and the direction of the patterns alternates sequentially. That is, one section of the spiral pattern on the inner wall of the main pipe 593 is forward and the other section is reverse. This process is repeated so that the mixture is guided to flow in spiral forward and reverse directions repeatedly as it enters the reactor 200 through the main pipe 593, thereby mixing the mixture again and further ensuring the full dissolution of the starch raw material.

[0031] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
