Description

Technical Field

[0001] This utility model relates to the field of swelling device structure, specifically to a swelling device used in the modification process of konjac glucomannan. Background Technology

[0002] Konjac glucomannan is a high-molecular-weight, non-ionic, water-soluble polysaccharide extracted from the tuber of konjac. It is the main component of konjac and has a variety of biological functions, including improving glucose and lipid metabolism, promoting immune function, preventing cell lipid peroxidation, and combating skin inflammatory factors.

[0003] To improve the properties of konjac glucomannan and expand its application range, it is necessary to modify konjac glucomannan. Among the modification methods, chemical modification is favored because it can reduce water absorption, improve physicochemical properties, enhance adsorption, and improve dough properties.

[0004] The raw material pretreatment stage of the chemical modification process of konjac glucomannan is the swelling of konjac glucomannan. Swelling involves dissolving KGM in water in a swelling tank. Existing swelling processes either involve dissolving at room temperature or by heating (temperature controlled at 50~60℃). Existing swelling processes have the following shortcomings:

[0005] (1) Since the molecular weight of KGM is usually 200,000 to 2,000,000 Da, the long chain structure leads to a low diffusion rate, so it dissolves slowly in water at room temperature.

[0006] (2) Although heating can increase the swelling rate, KGM is sensitive to temperature at high temperatures and is prone to partial degradation and gelation, which will affect the quality of the modified KGM solution in subsequent modification.

[0007] (3) The swollen solution has a clumping phenomenon, which affects the quality of the KGM solution in subsequent modification and use.

[0008] In view of the above, this application is hereby submitted. Utility Model Content

[0049] Example

[0050] Reference Figure 1As shown, this utility model embodiment provides a swelling device for the modification process of konjac glucomannan, including a pre-swelling body 1 and a heated swelling body 2. The pre-swelling body 1 is used for the room temperature pre-swelling of konjac glucomannan, and the heated swelling body 2 is used for heating and swelling the pre-swelled konjac glucomannan liquid. The top of the pre-swelling body 1 is provided with a first feeding port 3, and a sieve 4 is provided inside it. The first feeding port 3 is located above the sieve 4. The sieve 4 is configured to disperse the konjac glucomannan powder introduced by the first feeding port 3 and guide it to the bottom of the sieve 4 for swelling.

[0051] Specifically, the pre-swellable body 1, through room temperature pre-swelling, allows the konjac glucomannan (KGM) powder to initially absorb water and swell, reducing the degree of entanglement between its molecular chains and creating more favorable conditions for subsequent heating and swelling. The pre-swellable body 1 is equipped with a sieve 4, which disperses the added konjac glucomannan powder, preventing clumping when the powder is added directly. More specifically, the sieve 4 is located below the first feeding port 3, dispersing and sieving the konjac glucomannan powder introduced from the first feeding port 3 to prevent powder clumping and ensure uniform contact between the powder and water, thereby improving swelling efficiency. The heating swelling body 2, through heating, further accelerates the swelling process of KGM, allowing its molecular chains to fully unfold and improving swelling efficiency. In actual operation, the temperature can be controlled at 50~60℃ to prevent KGM from degrading or gelling at high temperatures.

[0052] During the operation, konjac glucomannan powder is first pre-swelled at room temperature in pre-swelling body 1, initially absorbing water and expanding. The pre-swelled liquid flows through a pipe into heated swelling body 2, where it is further heated and swelled at 50-60℃, allowing the KGM molecular chains to fully unfold. This staged swelling method avoids the degradation or gelation problems of KGM caused by direct high-temperature swelling, while improving swelling efficiency and balancing efficiency and stability. The sieving unit 4 disperses and sieves the added konjac glucomannan powder to prevent powder agglomeration, ensuring uniform contact between the powder and water, thereby improving the pre-swelling effect and solving the problem of agglomeration in the solution after swelling in existing technologies. This ensures that the pretreated KGM solution has better quality in subsequent modified applications.

[0053] For example, the pre-swollen body 1 includes a first cover 5 and a first cavity 6. A first stirrer 7 is disposed through the first cover 5. A first motor 8 is disposed on the first stirrer 7. The first motor 8 is used to drive the first stirrer 7 to rotate. The first stirrer 7 includes a first connecting rod 9 and at least one first stirring blade 10. The first stirring blade 10 is disposed on the first connecting rod 9. The sieve 4 is connected to the first connecting rod 9. When the first motor 8 drives the first connecting rod 9 to rotate, it can drive the first stirring blade 10 and the sieve 4 to rotate.

[0054] The pre-swollen body 1 has a first discharge port 18 at its bottom, and the heated swelling body 2 has a second feeding port 19 at its top. A guide pipe 20 is connected between the first discharge port 18 and the second feeding port 19, and a water pump 21 is installed on the guide pipe 20. The water pump 21 is used to transport the pre-swollen konjac glucomannan liquid into the heated swelling body 2. This structure, through the cooperation of the water pump 21 and the guide pipe 20, realizes the automated transportation of the pre-swollen liquid, reducing the complexity and labor intensity of manual operation. Moreover, the water pump 21 can quickly transport the liquid from the pre-swollen body 1 to the heated swelling body 2, improving the efficiency of the entire swelling process and shortening the production cycle. Preferably, a corresponding control valve can also be installed on the guide pipe 20 according to actual needs to improve the flexibility of the entire device.

[0055] In this embodiment of the invention, the first cover 5 is fixed to the top of the pre-swelled body 1, forming a sealed swelling space with the first cavity 6, which serves to seal and protect the internal components, while also providing support for the installation of the first stirrer 7. The first stirrer 7 promotes the mixing of konjac glucomannan powder and water through stirring, accelerating the room temperature pre-swelling process. The first connecting rod 9 connects the first motor 8 and the first stirring blade 10, serving as a transmission and support mechanism. The first stirring blade 10 is mounted on the first connecting rod 9 and is used to stir the liquid and powder within the pre-swelled body 1 to ensure uniform mixing. The first stirrer 7 penetrates the first cover 5, and the first motor 8 is installed outside the first cover 5. By driving the first connecting rod 9 to rotate, it drives the first stirring blade 10 and the sieve 4 to rotate.

[0056] Furthermore, in conjunction with reference Figure 1 and Figure 4 As shown, the heated swelling body 2 includes a second cover 22 and a second cavity 23. A receiving cavity 24 is provided on the outer wall of the second cover 22. An outlet 25 is provided at the top of the receiving cavity 24, and an inlet 26 is provided at the bottom. The inlet 26 is used to receive high-temperature fluid entering the receiving cavity 24, and the outlet 25 discharges the high-temperature fluid after it has cooled down in the receiving cavity 24. A second discharge port 27 is provided at the bottom of the heated swelling body 2. A second stirrer 28 is provided through the second cover 22. A second motor 29 is provided on the second stirrer 28, and the second motor 29 is used to drive the second stirrer 28 to rotate.

[0057] The second cover 22 is fixed to the top of the second cavity 23, forming a sealed heating space, which serves to seal and protect the internal components, and at the same time provides support for the installation of the second stirrer 28. The second cavity 23 is used to contain the pre-swollen konjac glucomannan liquid and to provide sufficient space for the liquid to swell during the heating process. The receiving cavity 24 is located on the outer wall of the second cover 22, adjacent to the second cavity 23 but independent of each other. The inlet 26 is located at the bottom of the receiving cavity 24 for receiving the high-temperature fluid, and the outlet 25 is located at the top of the receiving cavity 24 for discharging the cooled high-temperature fluid.

[0058] In this embodiment of the invention, a high-temperature fluid enters the receiving cavity 24 through inlet 26, transferring heat to the konjac glucomannan liquid in the second cavity 23, thus achieving indirect heating. This indirect heating method avoids direct contact between the liquid and the high-temperature heat source, reducing the risk of local overheating or degradation. After transferring heat, the high-temperature fluid in the receiving cavity 24 is discharged through outlet 25, completing the heat exchange process and achieving efficient heat utilization. Simultaneously, by controlling the fluid flow rate and temperature, precise control of the heating process is achieved. This structure, through indirect heating, enables more uniform heating of the liquid in the second cavity 23, avoiding degradation or gelation of konjac glucomannan caused by local overheating.

[0059] The second stirrer 28 penetrates the second cover 22 and extends into the second cavity 23. The second motor 29 provides power to the second stirrer 28, driving it to rotate. It should be noted that the structure of the second stirrer 28 is not limited here; any existing stirring structure can be used. For ease of understanding, the structure of the second stirrer 28 used in this embodiment is the same as that of the first stirrer 7, and will not be described in detail here.

[0060] Furthermore, to improve the overall ease of control of the device, such as... Figure 1 As shown, a first vent valve 30 can be installed on the pre-swelled body 1, and a second vent valve 31 can be installed on the heated swelling body 2; a first water inlet 32 ​​is installed on the pre-swelled body 1, and a second water inlet 33 is installed on the heated swelling body 2, with the first water inlet 32 ​​located below the sieve 4. A first control valve 34 is installed at the first discharge port 18, and a second control valve 35 is installed at the second discharge port 27; a temperature detector 36 is installed on the heated swelling body 2.

[0061] The first vent valve 30 can be designed as an automatic vent valve (such as a pressure-sensitive vent valve), which automatically opens when the internal pressure reaches a certain value, or it can be designed as a manual vent valve, which can be manually opened by the operator as needed. The first water inlet 32 ​​is used to add an appropriate amount of water to the pre-swelled body 1 so that the konjac glucomannan powder can be pre-swelled in water. By setting the water inlet below the sieve 4, it can be ensured that the added water first contacts the powder dispersed by the sieve 4, further optimizing the swelling effect. Of course, a corresponding control valve can also be set at the first water inlet 32.

[0062] The second vent valve 31 can prevent safety hazards caused by pressure buildup and ensure the safety of the heating and swelling process. Similarly, the second vent valve 31 can also be designed as an automatic vent valve (such as a pressure-sensitive vent valve), automatically opening when the internal pressure reaches a certain value, or as a manual vent valve, opened manually by the operator as needed. A corresponding control valve can also be installed at the second water inlet 33, connecting to an external piping system to supply water to the heating and swelling process. Through the first water inlet 32 ​​and the second water inlet 33, the operator can flexibly adjust the water volume according to actual needs to optimize the swelling effect.

[0063] The first control valve 34 controls the timing and flow rate of the pre-swollen konjac glucomannan liquid discharged from the pre-swollen body 1. During the discharge process, the first control valve 34 prevents liquid backflow and ensures the smooth progress of the discharge process. Similarly, both the first control valve 34 and the second control valve 35 can be designed as automatic control valves (such as solenoid valves or pneumatic valves), which are automatically opened and closed by the control system according to process requirements; or they can be designed as manual control valves, which are manually operated by the operator as needed. The second control valve 35 controls the timing and flow rate of the heated and swollen konjac glucomannan liquid discharged from the heated and swollen body 2. The temperature detector 36 is used to monitor the temperature inside the heated and swollen body 2 in real time to ensure that the heating process is carried out within the set temperature range.

[0064] In this embodiment of the invention, the timing and flow rate of liquid discharge after pre-swelling and heating swelling can be precisely controlled by the first control valve 34 and the second control valve 35, ensuring the continuity and stability of the swelling process. The temperature detector 36 ensures that the heating process is carried out within the set temperature range, further improving the swelling quality.

[0065] As a preferred embodiment of this utility model, refer to Figure 2As shown, the sieve component 4 includes a bottom plate 11, a top plate 12, and a vertical plate 13. The bottom plate 11 and the top plate 12 are connected by the vertical plate 13. The top plate 12 has an annular structure. The bottom plate 11 is provided with a plurality of sieve holes 42, and a through hole 14 is provided in the center of the bottom plate 11. The first connecting rod 9 passes through both the through hole 14 and the annular structure of the top plate 12. The first connecting rod 9 can slide axially within the through hole 14. The first connecting rod 9 is also provided with a limiting member 15, which is used to limit the sieve component 4 above the first stirring blade 10.

[0066] Specifically, the bottom plate 11 is provided with multiple sieve holes 42 for dispersing konjac glucomannan powder, preventing powder agglomeration, and ensuring its uniform distribution. Through holes 14 are used to accommodate the first connecting rod 9, allowing it to slide axially within the through holes 14. The top plate 12 has an annular structure, ensuring that the first connecting rod 9 can pass through it. The partial shielding structure of the top plate 12 can reduce the adhesion of konjac glucomannan powder to the inner wall of the pre-swollen body 1 above the sieving member 4, improving dispersion and guiding efficiency. The vertical plate 13 connects the bottom plate 11 and the top plate 12, forming a frame structure that allows the sieving member 4 to remain stable during stirring.

[0067] By connecting the sieve element 4 to the first connecting rod 9, it is ensured that the sieve element 4 can rotate together with the first connecting rod 9, achieving synchronous stirring and dispersion functions. The first connecting rod 9 can slide axially within the through hole 14, realizing a detachable and flexible adjustment structure. The limiting member 15 is installed on the first connecting rod 9 to limit the sieve element 4 above the first stirring blade 10 to adapt to different usage scenarios. The setting of the limiting member 15 ensures that the sieve element 4 always remains above the first stirring blade 10 during the stirring process, avoiding interference between the sieve element 4 and the first stirring blade 10, and ensuring the smooth progress of the stirring and sieving process. The limiting member 15 also prevents the sieve element 4 from detaching from the first connecting rod 9 during axial sliding, ensuring a stable connection between the sieve element 4 and the stirrer.

[0068] It should be noted that the specific structure of the limiting member 15 is not limited here, and existing limiting structures can be used as long as sufficient limiting stability can be achieved. In this embodiment of the utility model, exemplarily, in conjunction with... Figure 1 , Figure 2 and Figure 3 As shown, the first connecting rod 9 is provided with an external thread, and the limiting member 15 includes a first nut 16 and a second nut 17 sleeved on the first connecting rod 9; the first nut 16 is located above the through hole 14, and the second nut 17 is located below the through hole 14, and the first nut 16 and the second nut 17 are threadedly engaged with the first connecting rod 9.

[0069] Specifically, the external thread on the first connecting rod 9 provides the basis for the threaded engagement of the limiting member 15, allowing the first nut 16 and the second nut 17 to be firmly fixed on the first connecting rod 9. Through the threaded engagement, the first nut 16 and the second nut 17 can move axially on the first connecting rod 9, thereby achieving precise adjustment of the position of the screening member 4. This allows operators to flexibly adjust the position of the screening member 4 according to different stirring requirements and material characteristics, optimizing the stirring and dispersion effect. The threaded engagement provides sufficient friction to ensure that the limiting member 15 will not loosen during stirring, ensuring the stable fixation of the screening member 4. The first nut 16 and the second nut 17 limit the screening member 4 from both the top and bottom directions, ensuring that the screening member 4 will not move axially during stirring.

[0070] Preferably, reference Figure 5 As shown, the first connecting rod 9 has at least one groove 37; the first stirring blade 10 has a first steel sheet 38 and a second steel sheet 39. The first steel sheet 38 and the second steel sheet 39 are configured to fit the first stirring blade 10 onto the first connecting rod 9. The deformation capacity of the first steel sheet 38 and the second steel sheet 39 is configured to limit the first stirring blade 10 within the groove 37. This deformation capacity is the toughness, which is used to adjust the fit between the first steel sheet 38 and the second steel sheet 39 and the first connecting rod 9 under different needs, so as to flexibly adapt to the needs of adjustment and fixation. It should be noted that the number of first stirring blades 10 is not limited here. One, two, three, four, etc. can be set, which can be set according to actual needs. For ease of understanding, in this embodiment of the utility model, two first stirring blades 10 are provided, and correspondingly, the first connecting rod 9 has two grooves 37.

[0071] Specifically, the groove 37 provides guidance for the installation of the first stirring blade 10, enabling the stirring blade to be accurately installed in the predetermined position. The shape and size of the groove 37 can match the steel sheet on the first stirring blade 10, ensuring that the steel sheet can be firmly embedded in the groove 37. For example, the first steel sheet 38 and the second steel sheet 39 together sleeve the first stirring blade 10 onto the first connecting rod 9. Combined with the deformation capabilities of the first steel sheet 38 and the second steel sheet 39, the first stirring blade 10 is confined within the groove 37 of the first connecting rod 9, preventing axial movement of the stirring blade during stirring. More preferably, a limiting groove 40 is provided on the horizontal platform surface of the groove 37, and a limiting block 41 is provided on the first stirring blade 10. When the first steel sheet 38 and the second steel sheet 39 are located within the groove 37, the limiting block 41 can be inserted into the limiting groove 40. The shape and size of the limiting groove 40 preferably match the limiting block 41, ensuring that the limiting block 41 can be accurately and stably inserted into the limiting groove 40.

[0072] When the first steel plate 38 and the second steel plate 39 fix the stirring blade in the groove 37, the limiting block 41 can be inserted into the limiting groove 40 to further restrict the movement of the stirring blade. Preferably, the limiting block 41 can also be set as a rigid structure with a certain degree of flexibility. This embodiment of the invention further enhances the stability of the stirring blade through the cooperation of the limiting block 41 and the limiting groove 40, ensuring that the stirring blade will not move axially or circumferentially during stirring. At the same time, it makes the installation and disassembly of the stirring blade more convenient and quick, reducing maintenance time and costs. In other embodiments, the first stirring blade 10 and the first connecting rod 9 can be set as welded, bonded, or other structures; there are no restrictions here, as long as sufficient stirring stability can be achieved.

[0073] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model. It should be noted that the structures or components illustrated in the accompanying drawings are not necessarily drawn to scale, and descriptions of well-known components, processing techniques, and processes are omitted to avoid unnecessarily limiting the utility model.
