Description

Technical Field

[0001] The utility model relates to the technical field of starch production, in particular to a novel stirring barrel used for starch production. Background Art

[0002] Starch products are made from starch as raw material through mechanical, chemical or biochemical processing. Starch production is a complex and delicate process that requires raw material processing, crushing and refining, separation and washing, dehydration and drying, as well as crushing and packaging.

[0003] The patent document with application number 201821564500.8 discloses a stirring device for the production of starch products, including a main body, a universal wheel, a first motor, a hollow interlayer, a first fan, a second stirring rod, a second air duct, a suction pump and a spiral stirring blade. Four supporting legs are evenly installed under the main body, a first motor is installed on the left side of the first rotating shaft, a first crushing roller is installed on the first rotating shaft, a second motor is installed on the left side of the second rotating shaft, a second crushing roller is installed on the second rotating shaft, a filter is installed in the middle of the main body, and a hollow interlayer is arranged on the inner wall of the main body; a third motor is installed in the middle below the main body, a third rotating shaft is installed on the third motor, and a spiral stirring blade is installed between the first stirring rod and the second stirring rod.

[0004] However, when using traditional mixing barrels for starch production, during the crushing and refining process, if the stirring time is too long in the early stage of liquefaction, it will cause the starch granules to be damaged, affecting the subsequent saccharification and enzymatic hydrolysis reactions; for example: the treated starch raw materials need to be crushed and refined. The purpose of this step is to refine the raw materials so that the starch granules can be more easily dispersed in water to form a starch suspension. Liquefaction is the process of breaking up and dispersing the starch granules. Stirring can accelerate the mixing of starch granules and water. In the early stage of liquefaction, the stirring time should be as short as possible to avoid excessive damage to the starch granules and affect the subsequent saccharification and enzymatic hydrolysis reactions. Utility Model Content

[0005] The utility model discloses a novel stirring barrel for starch production, aiming to solve the technical problem that when a traditional stirring barrel for starch production is used, in the process of crushing and refining, if the stirring time is too long in the early stage of liquefaction, starch particles will be destroyed, thus affecting the subsequent saccharification and enzymolysis reactions.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A novel stirring barrel for starch production comprises a barrel body, wherein the barrel body is composed of a cover plate, a dispersion zone and a stirring zone, and further comprises:

[0008] Stirring mechanism: used for stirring starch particles in the stirring zone;

[0009] A guide baffle is provided inside the dispersion zone, and the guide baffle is composed of a plurality of fan plates, and each of the fan plates is provided with a plurality of annular holes, and a plurality of guide holes are opened on the inner wall of the annular hole, and leakage holes distributed at equal distances are opened at the edge of the guide baffle, and a slide groove is opened on the circumferential inner wall of the dispersion zone close to the stirring zone, and the guide baffle is slidably connected to the inside of the slide groove, and a motor is provided on the top outer wall of the cover plate, and a rotating shaft is connected to one end of the motor output shaft, and the guide baffle is connected to the circumferential outer wall of the rotating shaft.

[0010] In this scheme, starch particles are introduced into the dispersion zone, the motor is working, the shaft rotates and drives the guide baffle to rotate at the same time. Under the centrifugal effect, the starch particles are dispersed from the top position of the guide baffle to the edge, so that the starch particles are dispersed and fall through multiple annular holes, and then flow to the leakage hole position at the edge and fall. The dispersion is sufficient, and the guide holes inside the annular holes assist the starch particles to fall to avoid accumulation. In the early stage of liquefaction, the starch particles are fully dispersed through the guide baffle, and then mixed with water in the stirring mechanism for liquefaction and stirring, which avoids the destruction of starch particles due to too long stirring time. The starch particles are first dispersed and then stirred, and are fully fused, and the subsequent reaction effect is better.

[0011] Optionally, the guide baffles are distributed in an "umbrella" shape, and the annular holes on two adjacent fan plates correspond to each other.

[0012] By adopting the above technical scheme, during the rotation of the guide baffle, the "umbrella"-shaped guide baffle can make the starch particles fall from top to bottom without hindrance. The positions of the annular holes on each fan plate correspond to each other, and the annular holes are distributed from dense to sparse from the top to the bottom of the fan plate, so that after the starch particles are poured in, they first fall from the annular holes on the top, and then slowly disperse to fall below. There are more starch particles densely dispersed above the annular holes that fall, and the starch particles that have not fallen flow to the bottom and fall, without accumulation and blockage, and are fully dispersed.

[0013] Optionally, the leakage hole is configured as a semicircular structure, and the hole diameter of the leakage hole is twice the hole diameter of the guide hole.

[0014] By adopting the above technical solution, the semicircular leakage hole is adapted to the circumferential inner wall of the dispersion zone, and the guide hole assists the starch particles to fall inside the annular hole. The hole diameter of the leakage hole is larger than the hole diameter of the guide hole, so that the starch particles can fall better when they are dispersed and gathered at the leakage hole position, avoiding accumulation at the edge.

[0015] In a preferred embodiment, the stirring mechanism includes a plurality of stirring rods disposed inside the stirring zone, a rotating rod is connected to the bottom end of the rotating shaft, and a plurality of stirring rods are connected to the circumferential outer wall of the rotating rod.

[0016] By adopting the above technical solution, when the stirring mechanism is working, the motor drives the rotating shaft to rotate, and the rotating shaft drives the rotating rod to rotate, so that the stirring rod on the rotating rod stirs the dispersed starch particles in the stirring zone, the stirring effect is good, and the liquefaction is more complete.

[0017] As can be seen from the above, a new type of stirring barrel for starch production includes a barrel body, which is composed of a cover plate, a dispersion area and a stirring area, and also includes:

[0018] Stirring mechanism: used for stirring starch particles in the stirring zone;

[0019] A guide baffle is provided inside the dispersion zone, and the guide baffle is composed of a plurality of fan plates, and each of the fan plates is provided with a plurality of annular holes, and a plurality of guide holes are provided on the inner wall of the annular hole, and leakage holes are provided at the edge of the guide baffle at equal distances, and a chute is provided on the circumferential inner wall of the dispersion zone close to the stirring zone, and the guide baffle is slidably connected inside the chute, and a motor is provided on the top outer wall of the cover plate, and a rotating shaft is connected to one end of the motor output shaft, and the guide baffle is connected to the circumferential outer wall of the rotating shaft. The new stirring barrel for starch production provided by the utility model has the technical effect of fully dispersing starch particles in the early stage of liquefaction, which will not cause starch particles to accumulate and clog, and stirring after dispersion, thereby avoiding the damage of starch particles due to too long stirring time.

DETAILED DESCRIPTION

[0025] 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 a part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application usually described and marked in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0026] The utility model discloses a novel stirring barrel for starch production, which is mainly applied to traditional stirring barrels for starch production. During the crushing and refining process, if the stirring time is too long in the early stage of liquefaction, the starch particles will be destroyed, affecting the subsequent saccharification and enzymatic hydrolysis reactions.

[0027] Reference Figure 1 , Figure 2 and Figure 4 A new type of stirring barrel for starch production includes a barrel body, which is composed of a cover plate 4, a dispersion area 1 and a stirring area 2, and also includes:

[0028] Stirring mechanism: used to stir starch particles in stirring zone 2;

[0029] A guide baffle 12 is provided inside the dispersion zone 1. The guide baffle 12 is composed of a plurality of fan plates, and a plurality of annular holes 14 are opened on each fan plate. A plurality of guide holes 15 are opened on the inner wall of the annular hole 14. Leakage holes 16 distributed at equal distances are opened at the edge of the guide baffle 12. A slide groove is opened on the circumferential inner wall of the dispersion zone 1 close to the stirring zone 2. The guide baffle 12 is slidably connected to the inside of the slide groove. A motor 9 is provided on the top outer wall of the cover plate 4. A rotating shaft 10 is fixedly connected to one end of the output shaft of the motor 9, and the guide baffle 12 is connected to the circumferential outer wall of the rotating shaft 10.

[0030] In the specific working process, the starch particles are introduced into the dispersion area 1 of the barrel body, and the motor 9 is working. The motor 9 rotates at a low speed to drive the rotating shaft 10 to rotate, so that the guide baffle 12 on the rotating shaft 10 rotates at the same time. Under the centrifugal effect, the starch particles are dispersed from the top position of the guide baffle 12 to the edge, and the distribution of the annular holes 14 changes from dense to sparse, so that the starch particles are dispersed and fall from the annular holes 14 at the top, and then slowly dispersed through multiple annular holes 14, and finally flow to the leakage hole 16 at the edge. The guide holes 15 assist the starch particles to fall inside the annular holes 14. In the early stage of liquefaction, the starch particles are fully dispersed through the guide baffle 12, and then mixed with water in the stirring mechanism for liquefaction and stirring.

[0031] It should be noted that, during specific use, a slider is provided on the inner wall of the chute, and the slider is connected to the bottom edge of the guide baffle 12. When the guide baffle 12 rotates, the slider drives the guide baffle 12 to slide simultaneously in the chute, so that the starch particles can fall off and the sliding is smoother.

[0032] Among them, the guide baffles 12 are distributed in an "umbrella" shape, and the annular holes 14 on two adjacent fan plates correspond to each other. During the rotation of the guide baffles 12, the "umbrella"-shaped guide baffles 12 can make the starch particles fall from top to bottom without hindrance. The positions of the annular holes 14 on each fan plate correspond to each other, and the annular holes 14 are distributed from dense to sparse from the top to the bottom of the fan plate, so that after the starch particles are poured in, they first fall from the upper annular holes 14, and then slowly disperse to the bottom and fall. The starch particles above the annular holes 14 are densely dispersed and fall, and the particles that have not fallen flow to the bottom and fall, without accumulation and blockage, and are fully dispersed.

[0033] Among them, the leakage hole 16 is set to a semicircular structure, and the hole diameter of the leakage hole 16 is twice the diameter of the guide hole 15. The semicircular structure of the leakage hole 16 is adapted to the circumferential inner wall of the dispersion area 1. The guide hole 15 assists the starch particles to fall inside the annular hole 14. The hole diameter of the leakage hole 16 is larger than the hole diameter of the guide hole 15, so that the starch particles can be dispersed and gathered at the position of the leakage hole 16 and fall better to avoid accumulation at the edge.

[0034] Among them, the annular hole 14 is used in conjunction with the guide hole 15, and multiple guide holes 15 are located inside the annular hole 14. When the starch particles are dispersed and fall from the annular hole 14, the position of the guide holes 15 assists the starch particles to fall, thereby preventing the starch particles from accumulating at the position of the annular hole 14 and causing blockage. Multiple guide holes 15 cooperate with the annular hole 14 to fully disperse the starch particles.

[0035] Reference Figure 1 , Figure 2 and Figure 3 In a preferred embodiment, the stirring mechanism includes a plurality of stirring rods 13 arranged inside the stirring zone 2, a rotating rod 11 is fixedly connected to the bottom end of the rotating shaft 10, and the plurality of stirring rods 13 are fixedly connected to the circumferential outer wall of the rotating rod 11.

[0036] Specifically, when the stirring mechanism is working, the motor 9 drives the rotating shaft 10 to rotate, and the rotating shaft 10 drives the rotating rod 11 to rotate, so that the stirring rod 13 on the rotating rod 11 stirs the dispersed starch particles in the stirring area 2.

[0037] The stirring rod 13 is adapted to the inner diameter of the stirring zone 2 , so that the stirring rod 13 can perform stirring work inside the stirring zone 2 more smoothly without damaging the inner wall of the stirring zone 2 , and can also fully mix the starch particles and water in the stirring zone 2 .

[0038] Reference Figure 1 and Figure 2 In a preferred embodiment, four support rods 3 are provided on the circumferential outer wall of the barrel body, a spiral feeding pipe 5 is provided at the top of the cover plate 4, a water guide pipe 7 is provided on the outer wall of one side of the stirring zone 2, a discharge pipe 6 is provided on the bottom outer wall of the stirring zone 2, and a gate valve 8 is provided at the connection between the discharge pipe 6 and the stirring zone 2.

[0039] Specifically, the support rod 3 supports the barrel body to make the overall device more stable. The starch particles are fed into the dispersion zone 1 through the spiral feeding pipe 5. The water pipe 7 guides water from the outside into the stirring zone 2. After stirring, the starch mixture is discharged through the discharge pipe 6. The gate valve 8 is used to open and close the valve between the discharge pipe 6 and the stirring zone 2.

[0040] Working principle: When in use, first, feed the starch granules into the dispersion area 1 of the barrel through the spiral feeding tube 5, start the motor 9, and the motor 9 drives the rotating shaft 10 to rotate at a low speed, so that the guide baffle 12 and the stirring rod 13 rotate at the same time. The starch granules on the guide baffle 12 are dispersed from the top position of the guide baffle 12 to the edge under the action of centrifugation. Because the distribution of the annular holes 14 is from dense to sparse, the starch granules slowly disperse and fall from the annular holes 14 at the top to the multiple annular holes 14 below. The guide holes 15 assist the starch granules to fall inside the annular holes 14, and finally flow to the leakage holes 16 at the edge for dispersion. The fully dispersed starch granules fall into the stirring area 2 and are rotated and stirred by the stirring rod 13, and are fully stirred and mixed with the water introduced by the water guide pipe 7. After stirring, the gate valve 8 is opened to discharge the material through the discharge pipe 6.

[0041] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited to this. The replacement can be a replacement of part of the structure, device, method step, or a complete technical solution. Equivalent replacement or change based on the technical solution of the utility model and its utility model concept should be included in the protection scope of the utility model.
