Description

Technical Field

[0001] The invention relates to the technical field of isomaltooligosaccharide production, and in particular to a saccharification reaction device for producing isomaltooligosaccharide. Background Art

[0002] Isomaltooligosaccharide is a functional oligosaccharide with multiple physiological functions such as promoting the growth of intestinal probiotics, enhancing immunity, regulating blood sugar, etc. Therefore, it has been widely used in functional foods and health products. In industry, starch is generally used as raw material to make isomaltooligosaccharide. The starch is placed under appropriate temperature and pH conditions, and the starch is gradually converted into the finished product of isomaltooligosaccharide through processes such as hydrolysis, gelatinization, saccharification, and transglycoside.

[0003] Conventional processes generally directly mix starch with water to form a starch solution, which is then heated for gelatinization in preparation for the saccharification process. In the process of stirring starch or enzymes in a solution, when starch is added directly to the solution, the starch granules will quickly absorb water and swell when in contact with water. If the starch is not stirred in time, the material will easily agglomerate, so that the starch and enzyme cannot fully contact, resulting in an incomplete reaction process and waste of materials. A common method is to alleviate the phenomenon of material agglomeration by increasing the stirring speed. However, for construction safety, starch is generally added to the solution first, and then the stirring device is started. When the starch contacts the solution, a large amount of material agglomerates have already formed. In other words, the effect of reducing material agglomeration by increasing the stirring speed is limited. Summary of the invention

[0018] The purpose, features and advantages of the present invention will be further described with reference to the accompanying drawings in conjunction with the embodiments. DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0021] In addition, the descriptions of "first", "second", etc. in the present invention are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, "and / or" in the full text includes three solutions. Taking A and / or B as an example, it includes technical solution A, technical solution B, and technical solution that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, which must be based on the ability of ordinary technicians in the field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0022] like Figure 1 to Figure 9 As shown, the present invention provides a saccharification reaction device for producing isomaltooligosaccharide, comprising a tank body 1, a feed inlet 11 is provided at the top of the tank body 1, a powder mixing layer and a liquefaction layer are sequentially provided inside the tank body 1 in a direction downward from the feed inlet 11, the powder mixing layer is connected to the outside of the tank body 1 through the feed inlet 11, and a tray 14 is provided at the bottom of the powder mixing layer. A first partition 15 is provided below the tray 14, and the first partition 15, the tray 14 and the inner side wall of the tank body 1 form a liquefaction layer.

[0023] The material enters the powder mixing layer through the feed inlet 11. Inside the powder mixing layer, the material generally includes starch raw materials and enzymes required for related reactions, such as α-amylase. The material is preliminarily broken up and mixed in the powder mixing layer, and the lumps in the material are preliminarily removed to improve the mixing degree of the material. The liquefaction layer is provided with a water inlet pipe 12 connected to the external pipeline, and the liquefaction layer is provided with a steam disk 4. After the material enters the liquefaction layer, it is mixed with water. The steam disk 4 passes high-temperature steam into the interior of the liquefaction layer to form continuous bubbles, continuously stir the mixed solution of the material and water, further break up the lumps that may be formed after the material enters the water, and make the material more evenly distributed in the solution. The high-temperature steam heats the liquid inside the liquefaction layer to 90°C~100°C, which can promote the hydrolysis of starch into dextrin under the action of enzymes on the one hand, and soften the starch lumps on the other hand, break up the lumps, and facilitate the starch to be fully gelatinized.

[0024] The stirring mechanism 2 includes a rotating shaft 211, one end of which extends into the interior of the tank body 1, and the other end of which is outside the tank body 1 and is provided with a motor 21. A bracket 142 is provided at the top of the tank body 1 at a position corresponding to the motor 21. The part of the rotating shaft 211 inside the tank body 1 corresponding to the powder mixing layer is provided with a bulk blade 22, and a spiral blade 23 is provided corresponding to the liquefaction. Multiple groups of bulk blades 22 are fixedly connected to the rotating shaft 211, which can enhance the shearing effect of the bulk blades 22 on the powder and stir the materials in the powder mixing layer. A plurality of protrusions 221 are distributed in an array on the surface of the bulk blades 22. The protrusions 221 increase the irregularity of the blade surface, can better break up the powder, prevent the powder from sticking to the bulk blades 22, increase the fluidity of the powder during the mixing process, and improve the mixing degree of the materials. During the rotation process, the spiral blades 23 promote the solution in the liquefaction layer to roll up and down, and prevent starch from being deposited on the bottom surface of the liquefaction layer. The spiral blade 23 is provided with a plurality of through holes 231 arranged in an array. The presence of the through holes 231 can cause the material to form a local reflux during the pushing process of the spiral blade 23, increase the fluidity of the material, and prevent the material from accumulating on the spiral blade 23. During the process of the solution flowing through the through holes 231, the spiral blade 23 shears and breaks up the material agglomerates that may exist in the solution. The through hole 231 design can reduce the resistance during the rotation of the spiral blade 23, reduce the energy consumption during the operation of the equipment, and improve the economy of the equipment.

[0025] A sound wave generator 141 is provided in the powder mixing layer, and the tray 14 is annular. A side inclined plate 143 is provided on the outer circumference of the tray 14, and an inner platform 144 is provided on the inner circumference. A plurality of reflective plates 146 are provided on the circumference of one side of the side inclined plate 143 and the inner platform 144 located in the powder mixing layer, and the reflective plates 146 extend along the radial direction of the tray 14. A material trough 145 is provided between the side inclined plate 143 and the inner platform 144, and the material trough 145 is located at the bottom of the tray 14. When the sound wave generator 141 generates sound waves in the powder mixing layer, the sound waves make the material vibrate in the powder mixing layer, promote the flow and dispersion of the powder, prevent the powder from agglomerating, accelerate the mixing of the materials, and improve the production efficiency. The annular tray 14 facilitates the reflection of the sound waves in the powder mixing layer, enhances the vibration effect of the materials, facilitates the distribution of the materials, avoids the local accumulation of the materials, and improves the mixing effect. On the one hand, the side inclined plate 143 and the inner platform 144 increase the mixing area so that the powder is constantly stirred and mixed during the flow process. On the other hand, they can guide the material to flow to the material trough 145 during the mixing process, which is convenient for the material trough 145 to collect the material. The radially distributed reflector 146 can improve the reflectivity of sound waves, enhance the propagation effect of sound waves in the material, and further improve the mixing uniformity. A plurality of evenly spaced distribution ports 1451 are provided on the circumference of the material trough 145, and the distribution ports 1451 connect the liquefaction layer and the powder mixing layer. The material in the powder mixing layer is dispersed into the solution of the liquefaction layer through the plurality of distribution ports 1451 to prevent the material from being too concentrated when entering the solution. A first solenoid valve is provided on the side of the tray 14 located at the liquefaction layer at the position corresponding to the distribution port 1451, and the opening and closing degree of the distribution port 1451 is controlled by the first solenoid valve to control the flow rate of the material entering the liquefaction layer.

[0026] The steam disk 4 includes an external tube 41 and a disk body 42. The disk body 42 is provided with a plurality of gas nozzles 421 distributed in an array. The disk body 42 is connected to one end of the external tube 41, and the other end of the external tube 41 passes through the tank body 1 and is connected to an external pipeline. The external tube 41 serves as a steam delivery channel to ensure that steam can be efficiently and stably supplied to the inside of the tank body 1, meet process requirements, and realize smooth delivery of steam from the external pipeline to the inside of the tank body 1. The connection design between the disk body 42 and the external tube 41 forms a flow path for steam, ensuring that steam can smoothly enter the disk body 42 from the external pipeline and be ejected through the gas nozzle 421 to form continuous bubbles. The disk body 42 serves as a steam distributor, which can evenly transfer the heat of the steam and the bubbles to the solution in the liquefied layer, improve the utilization efficiency of heat, and stir the solution to prevent residual materials from agglomerating, so as to homogenize the solution components. On the one hand, multiple array-distributed air nozzles 421 can ensure that the steam is evenly distributed in the tank body 1, avoid local overheating or insufficient steam, and improve the uniformity of heating. The bubbles increase the contact area between the steam and the material, thereby improving the heating efficiency. On the other hand, evenly distributed bubbles can be produced in the liquefied layer, and the solution in the liquefied layer can be stirred to the same extent by the evenly distributed bubbles. The design of the array-distributed air nozzles 421 can reduce the load of a single air nozzle 421, reduce the risk of blockage, and ensure a continuous supply of steam.

[0027] The disc 42 includes a plurality of annular tubes 423, which are distributed along the radial direction of the disc 42, and the circumference of the annular tubes 423 gradually increases from the center to the periphery of the disc 42. This design enables the annular tubes 423 to cover a larger area, and each annular tube 423 is connected to the outer tube 41, ensuring that the steam can flow evenly into each annular tube 423. The structure of the annular tubes 423 not only increases the contact area between the disc 42 and the solution, but also significantly improves the heating efficiency of the disc 42. A larger contact area means that heat can be transferred to the solution more quickly and evenly, thereby accelerating the softening and hydrolysis process of starch. In the starch saccharification reaction, the softening of starch blocks is a key step. The design of the annular tubes 423 can effectively soften the starch blocks through efficient heating, prevent them from depositing or agglomerating, and promote the hydrolysis of starch. In addition, the distribution of the annular tubes 423 ensures the uniform transfer of heat on the disc 42, avoids the problem of local overheating or insufficient heating, and further improves the stability and efficiency of the reaction.

[0028] A plurality of support legs 422 are provided on the circumference of the side of the annular tube 423 close to the first partition 15, and a plurality of evenly spaced gas nozzles 421 are provided on the circumference of the side of the annular tube 423 away from the support legs 422. These gas nozzles 421 are evenly distributed on the surface of the annular tube 423, which helps to spray steam evenly, so that the solution in the liquefied layer can be fully mixed and heat transferred. Under the action of the support legs 422, the annular tube 423 is able to be away from the first partition 15. Such a design enables the annular tube 423 to fully contact the solution in the liquefied layer, which is conducive to improving the utilization efficiency of thermal energy. In addition, it can also effectively prevent the contact area between the annular tube 423 and the first partition 15 from being too large, thereby reducing heat loss. The support legs 422 not only play a supporting and fixing role, but they can also significantly enhance the structural stability of the annular tube 423. Especially in a high temperature and high pressure working environment, the support legs 422 can effectively prevent the annular tube 423 from deformation or displacement, ensuring that the equipment can operate stably and reliably for a long time. At the same time, the presence of the support feet 422 can also reduce the vibration and noise generated by the annular tube 423 during operation, thereby improving the running stability of the equipment.

[0029] Inside the tank body 1, a cooling layer, a saccharification layer, a transglycosylation layer and a concentration layer are sequentially arranged along the first partition 15 downward. The top of the cooling layer is the first partition 15, and the bottom is provided with a second partition 16. The top of the saccharification layer is the second partition 16, and the bottom is provided with a third partition 17. The top of the transglycosylation layer is the third partition 17, and the bottom is provided with a fourth partition 18. The fourth partition 18 forms a concentration layer with the bottom of the tank body 1. The rotating shaft 211 is provided with a first stirring paddle 24 corresponding to the saccharification layer, and the rotating shaft 211 is provided with a second stirring paddle 25 corresponding to the transglycosylation layer. The first stirring paddle 24 and the second stirring paddle 25 have a low shearing effect on the enzyme in the solution during rotation, which is conducive to maintaining the enzyme to maintain a stable structure and good activity. In the liquefaction layer, starch is gelatinized into dextrin. In the saccharification layer, β-amylase needs to be added for the saccharification reaction of dextrin. β-amylase needs to be in an environment of 55°C~60°C to maintain activity. β-amylase converts dextrin into maltose and glucose. The solution of the transglycosidation layer needs to be added with glucose transaside enzyme, which needs to be in an environment of 50°C to 60°C to remain active. Maltose and glucose undergo transaside reaction under the action of glucose transaside enzyme to form isomaltooligosaccharides. The solution containing isomaltooligosaccharides flows into the concentration layer, is heated, and the water inside the isomaltooligosaccharide solution is evaporated to concentrate into a high-concentration isomaltooligosaccharide solution. The first partition 15 is provided with a plurality of evenly spaced first material holes 151, and a second solenoid valve is provided on one side of the first partition 15 located in the cooling layer corresponding to the position of the first material hole 151.

[0030] The second partition 16 is provided with a plurality of evenly spaced second material holes 161, and a third solenoid valve is provided at the position corresponding to the second material holes 161 on the side of the second partition 16 located at the saccharification layer. The third partition 17 is provided with a plurality of evenly spaced third material holes 171, and a fourth solenoid valve is provided at the position corresponding to the third material holes 171 on the side of the third partition 17 located at the transglycoside layer. The third solenoid valve and the fourth solenoid valve are used to independently control the opening and closing degree of the second material holes 161 and the third material holes 171, respectively, to achieve precise regulation of material flow, ensure uniform flow of materials between the saccharification layer and the transglycoside layer, avoid local overload or underload, and improve reaction efficiency.

[0031] The tank body 1 is provided with a thermal cycle assembly 3, and the thermal cycle assembly 3 includes a first coil 32 and a second coil 34. The first coil 32 is located in the cooling layer, and the second coil 34 is located in the transglycoside layer. One end of the first coil 32 and the second coil 34 is connected through a connecting pipe 31, and the other end is connected through a return pipe 33. The first coil 32 and the second coil 34 form a closed loop through the connecting pipe 31 and the return pipe 33. The length direction of the connecting pipe 31 is sequentially provided with a pump body 35 and a storage box 36. The pump body 35 can promote the flow of the refrigerant in the thermal cycle assembly 3, and the refrigerant in the thermal cycle assembly can be supplemented through the storage box 36. The storage box 36 can be replaced by other devices for regulating the temperature of the refrigerant, such as a composite structure of a condenser or a heater. The high-temperature dextrin flows from the liquefaction layer into the cooling layer and contacts the first coil 32. The refrigerant inside the first coil 32 absorbs the heat of the high-temperature dextrin through heat transfer, so that the dextrin temperature drops to a temperature that meets the requirements of saccharification. The heat flows into the second coil 34 inside the transglycoside layer along with the flow of the refrigerant. The second coil 34 uses the heat of the refrigerant for the transglycoside reaction through heat transfer. The cooled refrigerant returns to the first coil 32 through the connecting pipe 31 under the action of the pump body 35.

[0032] The heat cycle component 3 can be used to efficiently transfer the excess heat in the dextrin cooling process to the transglycosidation layer, so as to fully utilize the heat. This design not only optimizes the distribution of energy, but also significantly reduces the energy consumption in the production process. In the gelatinization, saccharification and transglycosidation reaction processes, temperature is a key factor affecting enzyme activity and reaction efficiency. Through the heat cycle component 3, the heat absorbed by the cooling layer can be transferred to the transglycosidation layer, so as to maintain the suitable temperature required for the transglycosidation reaction, and avoid the enzyme activity decline or inactivation caused by temperature fluctuations. At the same time, the gelatinization process and the saccharification process can also be carried out in a stable temperature range to ensure the uniform decomposition of starch and prevent starch deposition or agglomeration caused by uneven temperature. Starch deposition not only blocks equipment components and affects the continuity of production, but also may cause material waste and increase production costs. The application of the heat cycle component 3 effectively solves the problem of low heat utilization rate, and through precise temperature control, ensures smooth material flow and reduces equipment failure rate. The reuse of heat reduces the dependence on external energy, further reduces production costs, and improves the economic benefits of production. The introduction of thermal cycle component 3 not only optimizes the reaction conditions and improves product quality, but also achieves efficient use of energy, providing reliable technical support for the production of isomaltooligosaccharides.

[0033] The fourth partition plate 18 is provided with a fourth material hole 181, and a filter cartridge 182 is provided on one side of the fourth partition plate 18 located at the concentration layer corresponding to the fourth material hole 181. An arched filter plate 1821 is provided at one end of the filter cartridge 182 close to the fourth material hole 181, and an activated carbon layer 1822 is filled inside the filter cartridge 182, and a semipermeable membrane 1823 is provided at the bottom of the filter cartridge 182. The transglycosidated solution passes through the fourth material hole 181 and enters the filter cartridge 182. This design ensures that the solution can be effectively introduced into the filtration device for further treatment. The existence of the filter cartridge 182 can perform preliminary filtration and treatment on the material flowing through, thereby effectively removing larger impurities and particles in the solution, and ensuring the smooth progress of subsequent processes. Compared with a flat filter plate, the arched structure provides a larger filtration area, thereby improving the filtration efficiency. At the same time, the arched filter plate 1821 can gather large particles of impurities or material agglomerates to the edge, and use the combined effect of gravity and liquid flow to effectively prevent the material from blocking the central part of the arched filter plate 1821, thereby ensuring the smooth progress of the filtration process. The arched structure can also enhance the structural strength of the filter cartridge 182. Under high pressure, this structure can better resist deformation and breakage, ensuring the stability and durability of the filter cartridge 182. The activated carbon layer 1822 filled inside the filter cartridge 182 has a large specific surface area and excellent adsorption performance, which can effectively remove impurities and harmful substances in the material. The microporous structure of the activated carbon enables it to capture and adsorb tiny particles and organic matter in the solution, thereby improving the purity and quality of the material. A semipermeable membrane 1823 is provided at the bottom of the filter cartridge 182, further improving the filtering effect. The semipermeable membrane 1823 has selective permeability, allowing some small molecules to pass through while blocking larger impurities and particles. In this way, the material can be further finely filtered to ensure that the purity of the filtered oligosaccharide is higher. Through the fine filtration of the semipermeable membrane 1823, the tiny particle impurities in the solution can be effectively removed, so that the purity and quality of the final product reach higher standards. Through this multi-level filtration design, the transglycosylated solution can be fully purified and treated after entering the filter cartridge 182. On the one hand, the combination of the arched filter plate 1821 and the activated carbon layer 1822 can effectively remove large particles and harmful substances in the solution, and on the other hand, the fine filtration of the semi-permeable membrane 1823 ensures the high purity of the final product. The efficiency and effect of the filtration process are optimized, ensuring the stability and reliability of the entire production process.

[0034] The concentration layer is a key structure for material concentration in industrial production. A discharge pipe 132 is provided at the bottom thereof for discharging the concentrated material out of the system. A heating body 19 is installed above the discharge pipe 132, and the heating body 19 can provide a continuous and stable heat source for the material in the concentration layer. The presence of the heating body 19 can not only accelerate the evaporation process of water or other solvents in the material, but also effectively improve the concentration efficiency, ensuring that the material reaches the required concentration in a shorter time. By heating, the water in the oligosaccharide solution can be quickly separated, thereby reducing the production cycle and improving the overall production efficiency. On the side of the concentration layer, an exhaust fan 13 is provided, and its main function is to discharge the water vapor or solvent vapor generated during the evaporation process out of the concentration layer in time. The operation of the exhaust fan 13 can prevent steam from accumulating and condensing in the system, and avoid equipment corrosion or material contamination problems caused by steam retention. In addition, the setting of the exhaust fan 13 can also maintain the negative pressure environment in the concentration layer, further promote the evaporation process, and ensure the stability of the concentration effect. In order to deal with the situation where the solution content in the concentrated layer is too high, an overflow pipe 131 is also provided on the side of the exhaust fan 13 close to the discharge pipe 132. The overflow pipe 131 connects the concentrated layer with the outside of the tank body 1 to form a safe discharge channel. When the solution concentration in the concentrated layer reaches a certain level, the excess solution can be quickly discharged through the overflow pipe 131 to avoid the solution overflowing or affecting the exhaust fan 13, thereby protecting the normal operation of the equipment. The design of the overflow pipe 131 not only improves the safety of the system, but also ensures the continuity and stability of the concentration process, avoiding equipment failure or production interruption caused by solution accumulation.

[0035] The heating body 19 is mainly composed of a main body 191 and a thermal resistor 193. The main body 191 is conical, which helps to reduce the accumulation of materials that may occur during the heating process, and can also increase the contact area between the material and the heating surface, thereby improving the heat transfer efficiency. The conical design allows the material to flow downward naturally under the action of gravity, avoiding the problem of local overheating or material retention, and ensuring that the heating process is more uniform and efficient. Inside the main body 191, there are multiple thermal resistors 193, which serve as heating elements and can provide accurate and stable heat sources. The distribution design of multiple thermal resistors 193 ensures that the required temperature can be quickly reached and maintained inside the heating body 19. The efficient operation of the thermal resistor 193 allows the water or other solvents in the material to evaporate quickly, significantly improving the concentration efficiency. The outer side of the main body 191 is provided with a spiral rib 192, which can guide the material to flow along the surface of the main body 191 and improve the stirring effect of the material. This flow can not only prevent the material from sintering or adhering to the surface of the heating body 19 due to long-term heating, but also increase the time the solution stays on the main body 191 and the contact area between the solution and the main body 191, thereby further improving the concentration effect and efficiency. The spiral ribs 192 allow the material to be fully mixed during the heating process, avoiding the situation where the local concentration is too high or too low, and ensuring the uniformity and stability of the concentration process. There are multiple openings 194 on the circumference of the bottom of the main body 191, and these openings 194 are channels for the discharge of the concentrated oligomaltose solution. When the material is concentrated in the heating body 19, the solution will pass through these openings 194 and finally be discharged from the tank body 1 from the discharge pipe 132. The distribution of multiple openings 194 ensures that the solution can be discharged evenly, further improves the operating efficiency and concentration effect of the equipment, and avoids the problem of equipment blockage caused by poor discharge.
