Description

Technical Field

[0001] This utility model relates to the field of resistant starch production, specifically a high-pressure wet heat treatment reaction device for resistant starch production. Background Technology

[0002] Resistant starch, also known as enzyme-resistant starch or indigestible starch, refers to starch that cannot be broken down by enzymes in the digestive tract and remains in the intestines, possessing some health-beneficial properties. The production processes of resistant starch can be mainly divided into three types: physical methods, chemical methods, and biological methods.

[0003] Physical methods refer to processing starch into a form with resistant starch properties. This involves adjusting the microstructure and morphology of starch to achieve higher resistance; specific processes include cooling, drying, and crystallization. When a starch solution is cooled, the starch molecules form a complex network structure, creating resistant starch.

[0004] High-pressure hydrothermal treatment of resistant starch is a physical modification method that alters the molecular structure of starch under high temperature, high humidity, and high pressure conditions to enhance its resistance to digestion. High temperature and high pressure partially gelatinize starch granules without completely destroying the crystalline regions. The high-moisture environment promotes the rearrangement of starch molecular chains to form a more stable resistant structure. During recrystallization of amylose, high pressure promotes the formation of a double helix structure in amylose, enhancing its resistance to enzymatic hydrolysis.

[0005] The effects of high-pressure hydrothermal treatment on starch granule structure include changes in starch granule morphology: the surface of starch granules shows depressions or cracks, but still maintains overall integrity, indicating incomplete gelatinization, reduced granule expansion, increased density, and high pressure inhibiting excessive swelling.

[0006] High-pressure hydrothermal treatment significantly improves the digestibility, thermal stability, and functional properties of starch by physically reorganizing the starch molecule structure, making it an effective method for producing resistant starches (especially RS2 and RS3). Its green and safe characteristics meet the health requirements of the modern food industry and have broad application prospects in the fields of functional foods and biomaterials.

[0007] Currently, when resistant starch is subjected to high temperature and high pressure treatment, the rapid temperature rise can lead to the destruction of the resistant starch structure. At the same time, the rapid evaporation of moisture at high temperatures can cause localized drying or uneven gelatinization, resulting in starch granules not being heated evenly or experiencing localized overheating and poor stability. This application aims to control temperature and pressure in stages, preheating and protecting resistant starch through different temperature zones, gradually regulating the structural changes of starch molecules, optimizing the formation efficiency and product quality of resistant starch, preventing localized overheating and excessive gelatinization of resistant starch, and maximizing the formation of resistant crystals. Utility Model Content

[0008] The purpose of this invention is to provide a high-pressure wet heat treatment reaction device for the production of resistant starch, so as to solve the problems in the prior art.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A high-pressure hydrothermal treatment reaction device for resistant starch production includes a reaction platform for dynamic high-temperature hydrothermal treatment of resistant starch. The reaction platform has a dynamic temperature control cavity inside, and several temperature control stations inside the reaction platform for multi-temperature dynamic temperature control of resistant starch. The temperature control station has several dynamic temperature zones, including a low-temperature zone, a medium-temperature zone, and a high-temperature zone for staged temperature and pressure control of resistant starch. Isolation and limiting components are provided between the dynamic temperature zones to isolate the material flow in each temperature zone.

[0011] By adopting the above technical solution: the reaction platform can perform dynamic high temperature and high pressure treatment on resistant starch, and the temperature control platform inside the dynamic temperature control cavity can perform multi-stage dynamic temperature control on resistant starch. The dynamic temperature zone can be set with low temperature zone, medium temperature zone and high temperature zone to perform staged temperature control on resistant starch. The isolation and limiting components can be used to insulate the low temperature zone, medium temperature zone and high temperature zone to avoid heat transfer between different dynamic temperature control zones.

[0012] Further configuration: The temperature control platform includes a first temperature control platform and a second temperature control platform. Both the first and second temperature control platforms are conical. The smaller diameter side of the first temperature control platform is sealed to the smaller diameter side of the second temperature control platform. The larger diameter side of the first temperature control platform is provided with a feed port for guiding resistant starch, and the larger diameter side of the second temperature control platform is provided with a discharge port for discharging resistant starch. The larger diameter side of the first and second temperature control platforms are respectively provided with a low temperature zone, a medium temperature zone, and a high temperature zone facing the smaller diameter side. Each of the low temperature zone, medium temperature zone, and high temperature zone is equipped with a pressure booster for pressurizing the resistant starch.

[0013] By adopting the above technical solution: the first temperature control station and the second temperature control station can perform high-temperature and high-pressure treatment on resistant starch. By setting the first temperature control station and the second temperature control station with conical platforms, the aperture of the resistant starch feed can be reduced, the feeding time of the resistant starch can be increased, and the heating of the resistant starch feed can be more uniform. The pressure boosters are respectively set in the low temperature zone, the medium temperature zone and the high temperature zone, which can dynamically control the pressure of the resistant starch.

[0014] Further configuration: Inside the reaction platform, near the first and second temperature control platforms and corresponding to the low-temperature, medium-temperature, and high-temperature zones, there are heating platforms for respectively controlling the temperature of the low-temperature, medium-temperature, and high-temperature zones. The heating platforms are respectively covered on the outside of the first and second temperature control platforms, and heating wires of different temperatures are set on the side near the first and second temperature control platforms. The heating wires are attached to the outside of the first and second temperature control platforms.

[0015] By adopting the above technical solution: the heating platform covers the first temperature control platform and the second temperature control platform and corresponds to the outside of the low temperature zone, the medium temperature zone and the high temperature zone. By adjusting the heating temperature of the heating wire, the temperature of the low temperature zone, the medium temperature zone and the high temperature zone inside the first temperature control platform and the second temperature control platform can be adjusted respectively. The temperature of the low temperature zone, the medium temperature zone and the high temperature zone can be adjusted one by one, which can reduce the drying cost of resistant starch.

[0016] Further configuration: The isolation and limiting component includes several cutting mesh plates for cutting and dispersing agglomerated resistant starch. The cutting mesh plates are respectively positioned between the low-temperature zone, the medium-temperature zone, and the high-temperature zone, and are detachably connected to the interior of the first temperature control platform and the second temperature control platform. The cutting aperture inside the cutting mesh plates at different positions in the low-temperature zone, the medium-temperature zone, and the high-temperature zone gradually decreases. The cutting mesh plates have hollow grooves inside, and heat insulation plates for isolating the heat transfer within the low-temperature zone, the medium-temperature zone, and the high-temperature zone are respectively installed inside the hollow grooves. The heat insulation plates are slidably connected inside the hollow grooves. The reaction platform has several operating storage platforms for storing the heat insulation plates. The operating storage platforms have sliding grooves inside, and the heat insulation plates are slidably stored inside the operating storage platforms. The operating storage platforms also have several high-temperature resistant cylinders for driving the heat insulation plates to move and insulate. The operating storage platforms are respectively sealed connected to the reaction platform, the first temperature control platform, and the second temperature control platform.

[0017] By adopting the above technical solution: the cutting mesh plate can cut and disperse the clumped resistant starch through its internal cutting aperture, avoiding clumping of resistant starch and uneven heating. The cutting aperture of the cutting mesh plate gradually decreases in different positions in the low temperature zone, medium temperature zone, and high temperature zone, which can disperse the clumped resistant starch one by one, while slowing down the falling speed of resistant starch and improving the degree of dispersion of resistant starch. The heat insulation plate is used to isolate the internal temperature heat transfer in the low temperature zone, medium temperature zone, and high temperature zone respectively. The heat insulation plate is moved inside the cutting mesh plate and inside the operating and receiving platform by a high temperature resistant cylinder, thereby providing heat insulation for different areas.

[0018] Further features: The surface of the heat insulation board is equipped with a temperature sensor for detecting the contact temperature of resistant starch, and the interior of the heat insulation board is equipped with a vibration sensor for vibrating and drying the agglomerated resistant starch.

[0019] By adopting the above technical solution: the temperature sensor is used to detect the heating temperature of resistant starch to avoid high-temperature gelatinization, and the vibration sensor can accelerate the dispersion and falling of agglomerated resistant starch to prevent resistant starch from sticking to the surface of the cutting mesh and the heat insulation plate.

[0020] Further configuration: The bottom of the reaction platform is equipped with a discharge platform for discharging resistant starch processed under high temperature and high pressure. The discharge platform has a left discharge zone and a right discharge zone. The left discharge zone is located below the discharge port in the second temperature control platform. The discharge platform also has an inclined platform for guiding the resistant starch from the discharge port into the right discharge zone. A telescopic insulating plate is provided between the left and right discharge zones for heat insulation. A slot is provided near the telescopic insulating plate on the discharge platform. A lifting cylinder is provided inside the slot to drive the telescopic insulating plate to rise and fall. A cooling pipe is provided at the top of the discharge platform near the right discharge zone for cooling the resistant starch. A limiting plate is provided on the cooling pipe to prevent direct blowing of the resistant starch. The limiting plate is detachably connected to the discharge platform.

[0021] By adopting the above technical solution: the discharge platform can discharge resistant starch after high temperature and high pressure treatment. The resistant starch is guided into the right discharge zone by the tilting platform. The telescopic insulating plate is raised and lowered by the lifting cylinder to isolate the heat in the left discharge zone. The air cooling pipe cools the resistant starch quickly. The limiting plate can prevent the air cooling pipe from blowing directly on the resistant starch, which would cause dust to be generated.

[0022] Compared with the prior art, the beneficial effects of this utility model are: it aims to control temperature and pressure in stages, preheat and protect resistant starch through different temperature zones, gradually regulate the structural changes of starch molecules, optimize the formation efficiency and product quality of resistant starch, prevent local overheating and excessive gelatinization of resistant starch, and maximize the formation of resistant crystals.

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-3 In this embodiment of the present invention, a high-pressure wet heat treatment reaction device for the production of resistant starch is provided. The device includes a reaction platform 1 for dynamic high-temperature wet heat treatment of resistant starch. The reaction platform 1 is provided with a dynamic temperature control cavity. The reaction platform 1 is provided with a plurality of temperature control stations for dynamic temperature control of resistant starch. The reaction platform 1 can perform dynamic high-temperature and high-pressure treatment of resistant starch. The temperature control stations inside the dynamic temperature control cavity can perform multi-stage dynamic temperature control of resistant starch.

[0030] The temperature control console has several dynamic temperature zones inside. The dynamic temperature zones include a low temperature zone 4, a medium temperature zone 5, and a high temperature zone 6 for staged temperature and pressure control of resistant starch. By setting the low temperature zone 4, the medium temperature zone 5, and the high temperature zone 6, the dynamic temperature zone can perform staged temperature control of resistant starch. The low temperature zone 4, the medium temperature zone 5, and the high temperature zone 6 are insulated by the isolation limiting component to prevent heat transfer between different dynamic temperature control zones.

[0031] The temperature control platform includes a first temperature control platform 2 and a second temperature control platform 3. Both the first temperature control platform 2 and the second temperature control platform 3 are conical. The smaller diameter side of the first temperature control platform 2 is sealed to the smaller diameter side of the second temperature control platform 3. The larger diameter side of the first temperature control platform 2 is provided with a feed port for guiding resistant starch. The larger diameter side of the second temperature control platform 3 is provided with a discharge port for discharging resistant starch. The larger diameter side of the first temperature control platform 2 and the smaller diameter side of the second temperature control platform 3 are respectively provided with a low temperature zone 4, a medium temperature zone 5, and a high temperature zone 6. Each of the low temperature zone 4, the medium temperature zone 5, and the high temperature zone 6 is equipped with a pressurizer for pressurizing the resistant starch.

[0032] The first temperature control platform 2 and the second temperature control platform 3 can perform high-temperature and high-pressure treatment on resistant starch. The conical platform of the first temperature control platform 2 and the second temperature control platform 3 can reduce the aperture of the resistant starch feed and increase the feeding time of the resistant starch, so that the resistant starch is heated more evenly. The pressure boosters are respectively set inside the low temperature zone 4, the medium temperature zone 5 and the high temperature zone 6, which can dynamically control the pressure of the resistant starch.

[0033] Inside the reaction platform 1, near the first temperature control platform 2 and the second temperature control platform 3, and corresponding to the low temperature zone 4, the medium temperature zone 5, and the high temperature zone 6, there is a heating platform 7 for respectively controlling the temperature of the low temperature zone 4, the medium temperature zone 5, and the high temperature zone 6. The heating platform 7 covers the outside of the first temperature control platform 2 and the second temperature control platform 3, and heating wires of different temperatures are set on the side near the first temperature control platform 2 and the second temperature control platform 3. The heating wires are attached to the outside of the first temperature control platform 2 and the second temperature control platform 3.

[0034] The heating platform 7 covers the first temperature control platform 2 and the second temperature control platform 3 and corresponds to the outer side of the low temperature zone 4, the medium temperature zone 5, and the high temperature zone 6. By adjusting the heating temperature of the heating wire, the temperature of the low temperature zone 4, the medium temperature zone 5, and the high temperature zone 6 inside the first temperature control platform 2 and the second temperature control platform 3 can be adjusted respectively. By adjusting the temperature of the low temperature zone 4, the medium temperature zone 5, and the high temperature zone 6 one by one, the drying cost of resistant starch can be reduced.

[0035] An isolation limiting component is provided between the dynamic temperature zones to isolate and guide the material in each temperature zone.

[0036] The isolation and limiting component includes several cutting mesh plates 8 for cutting and dispersing agglomerated resistant starch. The cutting mesh plates 8 are respectively disposed between the low temperature zone 4, the medium temperature zone 5, and the high temperature zone 6, and are detachably connected to the interior of the first temperature control platform 2 and the second temperature control platform 3. The cutting aperture of the cutting mesh plates 8 at different positions in the low temperature zone 4, the medium temperature zone 5, and the high temperature zone 6 gradually decreases. The cutting mesh plates 8 have a hollow groove inside, and the hollow groove is provided with heat insulation plates 10 for isolating the heat transfer in the low temperature zone 4, the medium temperature zone 5, and the high temperature zone 6, respectively. The heat insulation plates 10 are slidably connected inside the hollow groove. The reaction platform 1 is provided with several operation receiving platforms 9 for receiving the heat insulation plates 10. The operation receiving platform 9 is provided with a sliding groove, and the heat insulation plates 10 are slidably received inside the operation receiving platform 9. The operation receiving platform 9 is also provided with several high-temperature resistant cylinders for driving the heat insulation plates 10 to move and insulate. The operation receiving platform 9 is sealed and connected to the reaction platform 1, the first temperature control platform 2, and the second temperature control platform 3, respectively.

[0037] The cutting mesh plate 8 can cut and disperse the clumped resistant starch through its internal cutting aperture, avoiding clumping and uneven heating. The cutting aperture of the cutting mesh plate 8 gradually decreases in different positions in the low temperature zone 4, medium temperature zone 5, and high temperature zone 6, which can disperse the clumped resistant starch one by one, while slowing down the falling speed of the resistant starch and improving the degree of dispersion. The heat insulation plate 10 is used to isolate the heat transfer inside the low temperature zone 4, medium temperature zone 5, and high temperature zone 6. The heat insulation plate 10 is moved inside the cutting mesh plate 8 and the operating and receiving table 9 by a high temperature resistant cylinder, thereby providing heat insulation for different areas.

[0038] The surface of the heat insulation plate 10 is provided with a temperature sensor for detecting the contact temperature of resistant starch, and the interior of the heat insulation plate 10 is provided with a vibration sensor for vibrating and drying the agglomerated resistant starch.

[0039] Temperature sensors are used to detect the heating temperature of resistant starch to prevent high-temperature gelatinization. Vibration sensors can accelerate the dispersion and falling of agglomerated resistant starch, preventing it from sticking to the surfaces of the cutting mesh plate 8 and the heat insulation plate 10.

[0040] The bottom of the reaction platform 1 is provided with a discharge platform 11 for discharging resistant starch treated under high temperature and high pressure. The discharge platform 11 is provided with a left discharge zone 12 and a right discharge zone 13. The left discharge zone 12 is located below the discharge port in the second temperature control platform 3. The discharge platform 11 is provided with an inclined platform 14 for guiding the resistant starch from the discharge port into the right discharge zone 13. A telescopic insulating plate is provided between the left discharge zone 12 and the right discharge zone 13 for heat insulation. The discharge platform 11 is provided with a slot near the telescopic insulating plate. The slot is provided with a lifting cylinder for raising and lowering the telescopic insulating plate. The top of the discharge platform 11 near the right discharge zone 13 is provided with an air-cooling pipe for cooling the resistant starch. The air-cooling pipe is provided with a limiting plate for preventing direct blowing of the resistant starch. The limiting plate is detachably connected to the discharge platform 11.

[0041] The discharge platform 11 can discharge resistant starch after high temperature and high pressure treatment. The resistant starch from the discharge port is guided into the right discharge zone 13 by the tilting platform 14. The telescopic insulating plate is raised and lowered by the lifting cylinder to isolate the heat of the left discharge zone 12. The air cooling pipe cools the resistant starch quickly. The limiting plate can prevent the air cooling pipe from blowing directly on the resistant starch, which would cause dust to be generated by the resistant starch.

[0042] The working principle of this invention is as follows: the operator places the resistant starch to be treated under high temperature and pressure inside the temperature control platform of the reaction table 1 through the feed port. The resistant starch is fed onto the heat insulation plate 10 of the cutting mesh plate 8. The heating platform 7 and vibration sensor corresponding to the outer side of the low temperature zone 4 are turned on. The heating wire inside the heating platform 7 is automatically adjusted to the set temperature. The vibration sensor can accelerate the dispersion and falling of the clumped resistant starch, preventing the resistant starch from sticking to the surface of the cutting mesh plate 8 and the heat insulation plate 10. The temperature sensor is used to detect the heating temperature of the resistant starch to prevent high-temperature gelatinization. When the heating time of the low temperature zone 4 is reached, the heating platform 7 and vibration sensor corresponding to the outer side of the medium temperature zone 5 are turned on. At the same time, the heating platform 7 corresponding to the low temperature zone 4 can be turned off depending on whether there is subsequent resistant starch reaction treatment. The high temperature resistant cylinder is turned on, and the high temperature resistant cylinder drives the heat insulation plate 10 to rotate. The hot plate 10 moves and extends within the cutting mesh plate 8 and the operating and receiving table 9, allowing the resistant starch to be fed into the medium temperature zone 5 for further drying. When the drying time in the medium temperature zone 5 is met, the heat insulation plate 10 corresponding to the medium temperature zone 5 shrinks, allowing the resistant starch to be fed into the high temperature zone 6 for enhanced resistant starch crystallization. The resistant starch is then subjected to high temperature and high pressure treatment sequentially from the first temperature control table 2 and the second temperature control table 3. The pressure boosters are respectively located in the low temperature zone 4, the medium temperature zone 5, and the high temperature zone 6, which can dynamically control the pressure of the resistant starch. The starch is fed from the outlet of the second temperature control table 3 to the outlet table 11. The resistant starch from the outlet is guided into the right outlet zone 13 by the tilting table 14. The lifting cylinder drives the telescopic insulating plate to rise and fall, isolating the heat in the left outlet zone 12. The air-cooling pipe rapidly cools the resistant starch to room temperature.

[0043] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
