Description

Technical Field

[0001] The present invention relates to the technical field of polydextrose production, and particularly to a concentration device and method for processing polydextrose dietary fiber. Background Art

[0002] Polydextrose is a water-soluble dietary fiber, which is white or off-white solid particles, easily soluble in water with a solubility of 70%, the pH value of a 10% aqueous solution is 2.5 - 7.0, and it has no special taste. It is a food component with health care functions and can supplement the water-soluble dietary fiber required by the human body. After entering the human digestive system, it produces special physiological and metabolic functions, thereby preventing and treating constipation and fat deposition.

[0003] Polydextrose is a D-glucose polymer formed by vacuum polycondensation after mixing glucose, sorbitol and citric acid in a specific ratio and heating them into a molten mixture.

[0004] Existing concentration devices will adopt the method of evaporation concentration as needed when concentrating polydextrose dietary fiber to reduce its moisture content for subsequent processing. However, during concentration, since the polydextrose solution is located in the bottom area of the device and its lateral thickness is relatively wide, the heat transfer penetration effect will be affected and gradually decrease during the transfer of concentration heat. As a result, the temperature at the central part of the polydextrose solution is lower than that of the surrounding area, leading to poor heating efficiency and affecting the concentration effect.

Detailed implementation manners

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0034] A concentration device for processing polydextrose dietary fiber disclosed by the present invention is mainly applied to the scenario where, during concentration, since the polydextrose solution is located in the bottom area of the device and its lateral thickness is relatively wide, when heat transfer for concentration occurs, the penetration effect of heat transfer will be affected and gradually decrease, thus affecting the concentration effect.

[0035] Referring to Figures 1 - 10 , a concentration device for processing polydextrose dietary fiber includes a fixed bracket 1. An inner wall of the fixed bracket 1 is fixedly connected with a concentration chamber 3. An observation window 2 is arranged on the concentration chamber 3, and a heating interlayer 15 is arranged inside the concentration chamber 3. A heating cavity is formed between the heating interlayer 15 and the concentration chamber 3. A concentration heat transfer module 16 and a water condensation prevention module 17 are arranged inside the concentration chamber 3, and the water condensation prevention module 17 is located above the concentration heat transfer module 16. A raw material pipe 7 and a discharge pipe 13 are arranged on the concentration chamber 3, and a control valve 14 is arranged on the discharge pipe 13.

[0036] The concentration heat transfer module 16 includes a lifting chamber 1604. The lifting chamber 1604 is located inside the concentration chamber 3, and four installation openings are formed in the lifting chamber 1604. Heat transfer guide pipes 1605 are arranged inside the four installation openings.

[0037] The water condensation prevention module 17 includes an installation ball seat 1712, and a water condensation scraping member 1715 is arranged on the installation ball seat 1712.

[0038] Specifically, a heating cavity is formed between the heating interlayer 15 and the concentration chamber 3, which is convenient for performing water bath heating on the polydextrose solution during use; the observation window 2 is convenient for staff to observe the concentration situation of the polydextrose solution during use; the concentration heat transfer module 16 can make the polydextrose solution in a sheet-like conveying state when heated, so as to reduce the lateral width of the polydextrose solution, enable heat during concentration to better penetrate the polydextrose solution, make it quickly heated, and meet the concentration requirements of polydextrose; the water condensation prevention module 17 can scrape the water condensed on the inner wall of the top of the concentration chamber 3 during use, thereby reducing the situation of water condensing into drops, and further reducing the situation of condensed water falling, increasing the use effect of the device, and meeting the concentration requirements.

[0039] Referring to Figures 3 - 7, in a preferred embodiment, the concentration heat transfer module 16 further includes a fixing frame 1606 and a fixing ring frame 1601. The fixing frame 1606 is fixedly connected to the inner wall of the bottom of the concentration bin 3, and the fixing ring frame 1601 is fixedly connected to the inner wall of the concentration bin 3. A fixing rod 1602 is fixedly connected to the fixing frame 1606. The lifting bin 1604 is movably connected to the outer wall of the fixing rod 1602. An adjusting turntable 1608 and a mounting bracket 1607 are provided on the fixing ring frame 1601. A gear ring 1611 is fixedly connected to the top of the adjusting turntable 1608. An installation frame 1610 is provided on the top of the gear ring 1611. A universal motor 1613 is provided on the mounting bracket 1607. The output shaft of the universal motor 1613 is connected to a driving gear 1614 through a coupling. The driving gear 1614 meshes with the gear ring 1611. A driving shaft rod 1616 and two shaft rods 1619 are provided on the installation frame 1610. Adjusting rollers 1617 are fixedly connected to the outer walls of the two shaft rods 1619. Connecting cables 1603 are provided on the two adjusting rollers 1617. One ends of the two connecting cables 1603 are fixedly connected to the top of the lifting bin 1604. Two installation holes are formed in the top of the adjusting turntable 1608. Guide kits 1612 are fixedly connected to the inner walls of the two installation holes. The two connecting cables 1603 respectively pass through the interiors of the two guide kits 1612. Gear members 1615 are fixedly connected to the outer walls of the driving shaft rod 1616 and one of the shaft rods 1619. The two gear members 1615 mesh with each other. Linkage wheels 1620 are fixedly connected to one ends of the driving shaft rod 1616 and the other shaft rod 1619. The same linkage belt 1618 is provided on the outer walls of the two linkage wheels 1620. A servo motor 1609 is fixedly connected to the outer wall of one side of the installation frame 1610. The output shaft of the servo motor 1609 is connected to the other end of the shaft rod 1619 through a coupling. A plurality of discharge bins 1626 are arranged inside the lifting bin 1604. A plurality of round holes 1625 are formed in the outer walls of the plurality of discharge bins 1626. Connecting pipes 1621 are fixedly connected to the input ends of the plurality of discharge bins 1626. The input ends of three connecting pipes 1621 on the same side are fixedly connected to the same delivery pump 1622. Connecting pipes 1624 are fixedly connected to the input ends of the two delivery pumps 1622. Lifting suction nozzles 1623 are fixedly connected to the input ends of the two connecting pipes 1624.

[0040] Specifically, during heating and concentration, the servo motor 1609 operates. The servo motor 1609 drives one of the shaft rods 1619 to rotate, and the shaft rod 1619 cooperates with the linkage wheel 1620 and the linkage belt 1618 to drive the drive shaft rod 1616 to rotate. Since gear parts 1615 are provided on the drive shaft rod 1616 and the other shaft rod 1619, and the gear parts 1615 are meshed with each other, the adjusting rollers 1617 on the two shaft rods 1619 can rotate synchronously and in opposite directions. At this time, the connecting cable 1603 is wound or relaxed according to the height of the polydextrose solution inside the concentration tank 3 to adjust the position of the lifting suction nozzle 1623. When the lifting suction nozzle 1623 is adjusted to the appropriate height, the delivery pump 1622 is started. The delivery pump 1622 transports the polydextrose solution into the connecting conduit 1621 through the communicating conduit 1624 and the lifting suction nozzle 1623, and further transports it into the discharge bin 1626. At this time, the polydextrose solution can be transported into the lifting bin 1604 through the round hole 1625 on the discharge bin 1626. Then, the polydextrose solution inside the lifting bin 1604 will flow out through the heat transfer guiding pipe 1605 and be re-transported into the polydextrose solution inside the concentration tank 3 (during this process, the polydextrose solution is in a sheet-like transport state, so that the heat of concentration can effectively penetrate the polydextrose solution, improve the heat penetration, and increase the heating rate of the polydextrose solution). At the same time, when the polydextrose solution falls, the general motor 1613 drives the drive gear 1614 to rotate. Since the drive gear 1614 is meshed with the gear ring 1611, the adjusting turntable 1608 can be driven to rotate, so that the polydextrose solution rotates while falling, and the lifting suction nozzle 1623 lifts and transports the solution at different positions in the central area of the polydextrose solution (to ensure the uniformity of heat reception during concentration), until the concentration is completed.

[0041] In a specific application scenario, the concentration heat transfer module 16 is applicable to the concentration link of the polydextrose solution. That is, when the concentration heat transfer module 16 conducts concentration, it can lift and transport the polydextrose solution, and after transportation, make it fall in a sheet-like manner, thereby reducing the lateral width of the polydextrose solution, enabling the heat to better penetrate the polydextrose solution, and then enabling it to be heated quickly, thereby increasing the water evaporation rate of the solution, and further increasing the concentration efficiency of the device. And when conducting concentration, the device can be adjusted to an appropriate height according to the total amount of the polydextrose solution for convenient concentration operation. At the same time, the device can rotate the polydextrose solution when it is transported and falls in a sheet-like manner, so that the lifting suction nozzle 1623 lifts and transports the solution at different positions in the central area of the polydextrose solution to ensure the uniformity of heat reception during concentration, thereby increasing the heat reception effect of the device during concentration.

[0042] Refer to Figure 3 、 Figure 8 、 Figure 9 and Figure 10, in a preferred embodiment, the waterproof condensation module 17 further includes a water collecting base 1702. The water collecting base 1702 is fixedly connected to the inner wall of the top of the concentration bin 3. A driving motor 1703 is provided at the bottom of the water collecting base 1702. The output shaft of the driving motor 1703 is connected to a connecting bracket 1717 through a coupling. A communicating pump 1709 is fixedly connected to the top of the connecting bracket 1717. The output end of the communicating pump 1709 is fixedly connected to a water guide pipe 1707. The output end of the water guide pipe 1707 is fixedly connected to a rotary joint 1710. The rotary joint 1710 is arranged on the water collecting base 1702. And the input end of the communicating pump 1709 is fixedly connected to a connecting hose 1716. The input end of the connecting hose 1716 is communicated with the inside of the water condensation scraper 1715; An electric push rod 1704 is arranged on the connecting bracket 1717. The output end of the electric push rod 1704 is fixedly connected to a fixing member 1708. An electric telescopic rod 1711 is arranged on the fixing member 1708. The mounting ball seat 1712 is fixedly connected to the output end of the electric telescopic rod 1711. And a through pipe 1706 is fixedly connected to the outer wall of the water collecting base 1702. The output end of the through pipe 1706 is fixedly connected to a discharge pump 1705. The output end of the discharge pump 1705 is fixedly connected to a drain pipe 1701. The drain pipe 1701 is located outside the concentration bin 3; A support member 1713 is fixedly connected to the outer wall of the mounting ball seat 1712. Three reset spring rods 1714 are arranged on the support member 1713. And one end of each of the three reset spring rods 1714 is fixedly connected to the outer wall of the water condensation scraper 1715.

[0043] Specifically, during the concentration process, the electric telescopic rod 1711 and the electric push rod 1704 are started. The position of the electric telescopic rod 1711 is adjusted through the electric push rod 1704, and the height of the mounting ball seat 1712 and the water condensation scraper 1715 is adjusted through the electric telescopic rod 1711, so that the water condensation scraper 1715 contacts the inner wall of the top of the concentration bin 3 (the water condensation scraper 1715 has a certain elasticity and can effectively fit the arc of the top of the concentration bin 3 in cooperation with the mounting ball seat 1712 during adjustment). After contact, the driving motor 1703 is started. The driving motor 1703 can drive the connecting bracket 1717 to rotate, so that the water condensation scraper 1715 scrapes the condensed water on the inner wall of the top of the concentration bin 3, and conveys it to the inside of the water guide pipe 1707 through the connecting hose 1716 and the communicating pump 1709, and then conveys it to the inside of the water collecting base 1702. Then the discharge pump 1705 is started, and the scraped water is conveyed to the drain pipe 1701 through the through pipe 1706 for discharge, avoiding water condensation into drops. After use, the water condensation scraper 1715 can be reset through the reset spring rods 1714;

[0044] In a specific application scenario, the waterproof condensation module 17 is applicable to the concentrated water evaporation link, that is, when the waterproof condensation module 17 is in use, it can scrape the condensed water on the inner wall of the top of the concentration bin 3, thereby reducing the occurrence of water condensation into drops, and further reducing the occurrence of water droplets condensing and falling, so as to increase the use effect of the device. At the same time, by reducing the backflow of water droplets, the concentration efficiency of the device can be further increased. And when performing waterproof dripping condensation, the device can also collect the condensed water droplets inside the water pipe 4, avoiding the situation of water condensation backflow, and further increasing the use effect of the device.

[0045] Refer to Figure 1 、 Figure 2 and Figure 3 , in a preferred embodiment, a water pipe 4 is provided at the top of the concentration bin 3. A condensation bin 8 is provided on the outer wall of the water pipe 4. A condensation water port 5 and a heat preservation connecting pipe 6 are provided on the condensation bin 8. The output end of the heat preservation connecting pipe 6 is fixedly connected to a communication bin 9. A water inlet pipe 10 is fixedly connected to one outer wall of the communication bin 9, and a conveying pipe 11 is fixedly connected to the other outer wall of the communication bin 9. The output end of the conveying pipe 11 is communicated with the inside of the heating chamber, and a water outlet pipe 12 is fixedly connected to the outer wall of the concentration bin 3. The input end of the water outlet pipe 12 is communicated with the inside of the heating chamber.

[0046] Specifically, as the concentration progresses, the evaporated water will be discharged through the water pipe 4. At this time, condensed water can be introduced into the condensation bin 8 through the condensation water port 5, and the water is condensed by the condensed water and discharged after condensation (for easy collection by the staff). And while the condensation is carried out, the condensed water that absorbs heat will be transported into the heat preservation connecting pipe 6 and further transported into the communication bin 9, so as to be transported into the heating chamber along with the hot water entering through the water inlet pipe 10 (to absorb and utilize the condensation heat).

[0047] In a specific application scenario, the condensation bin 8 can condense the water vapor inside the water pipe 4 to facilitate its collection. At the same time, when condensing, the heat absorbed by the condensed water can be transported to the communication bin 9 through the heat preservation connecting pipe 6 and transported into the heating chamber along with the hot water transported by the water inlet pipe 10 for the concentration of the polydextrose solution, so that the device can recycle the heat absorbed by condensation, thereby increasing the use effect of the device.

[0048] A concentration method for polydextrose dietary fiber processing, using a concentration device for polydextrose dietary fiber processing as described above, includes the following steps:

[0049] Step 1: When in use, transport the polydextrose solution into the concentration bin 3 through the raw material pipe 7, and transport hot water into the communication bin 9 and the conveying pipe 11 through the water inlet pipe 10, and then transport it into the heating chamber for concentration heating.

[0050] Step 2: During heating and concentration, the servo motor 1609 operates, driving one of the shaft rods 1619 to rotate through the servo motor 1609. The shaft rod 1619 cooperates with the linkage wheel 1620 and the linkage belt 1618 to drive the drive shaft rod 1616 to rotate. Since gear parts 1615 are provided on the drive shaft rod 1616 and the other shaft rod 1619, and the gear parts 1615 are meshed with each other, the adjusting rollers 1617 on the two shaft rods 1619 can rotate synchronously and in opposite directions. At this time, the connecting cable 1603 is wound or relaxed according to the height of the polydextrose solution inside the concentration tank 3 to adjust the position of the lifting suction nozzle 1623. When the lifting suction nozzle 1623 is adjusted to the appropriate height, the delivery pump 1622 is started. The delivery pump 1622 transports the polydextrose solution to the inside of the connecting conduit 1621 through the connecting conduit 1624 and the lifting suction nozzle 1623, and further transports it to the inside of the discharge bin 1626. At this time, the polydextrose solution can be transported to the inside of the lifting bin 1604 through the round hole 1625 on the discharge bin 1626. After that, the polydextrose solution inside the lifting bin 1604 will flow out through the heat transfer guide pipe 1605 and be re-transported into the polydextrose solution inside the concentration tank 3. At the same time, when the polydextrose solution falls, the general-purpose motor 1613 drives the drive gear 1614 to rotate. Since the drive gear 1614 is meshed with the gear ring 1611, the adjusting turntable 1608 can be driven to rotate, so that the polydextrose solution rotates while falling, and the lifting suction nozzle 1623 lifts and transports the solution at different positions in the central area of the polydextrose solution until the concentration is completed.

[0051] Step 3: During concentration, the electric telescopic rod 1711 and the electric push rod 1704 are started. The position of the electric telescopic rod 1711 is adjusted through the electric push rod 1704, and the height of the mounting ball seat 1712 and the water condensation scraping member 1715 is adjusted through the electric telescopic rod 1711, so that the water condensation scraping member 1715 contacts the inner wall of the top of the concentration tank 3. After contact, the drive motor 1703 is started. The drive motor 1703 can drive the connecting bracket 1717 to rotate, and then the water condensation scraping member 1715 scrapes the condensed water on the inner wall of the top of the concentration tank 3, and transports it to the inside of the water guide pipe 1707 through the connecting hose 1716 and the connecting pump 1709, and then transports it to the inside of the water collection seat 1702. After that, the discharge pump 1705 is started, and the scraped water is transported to the drain pipe 1701 through the through pipe 1706 for discharge.

[0052] Step 4: After concentration, the control valve 14 is opened, and the concentrated polydextrose solution is transported out of the concentration tank 3 through the discharge pipe 13 and collected.
