Description

Technical Field

[0001] This invention belongs to the technical field of enzymatic hydrolysis reaction devices, specifically relating to a temperature-controlled enzymatic hydrolysis reaction device for rice starch lipid substitute. Background Technology

[0002] During the enzymatic hydrolysis of rice starch, enzymes such as amylase act on rice starch molecules, breaking them down into carbohydrate chains of varying lengths, thus forming substitutes with fat-like properties. For example, α-amylase can act on the α-1,4-glycosidic bonds within starch molecules, causing starch hydrolysis and producing products such as short-chain dextrins. Other enzymes, such as glycosyltransferases, can further modify dextrins, altering their molecular structure and properties to obtain substitutes with fat-like taste and functional characteristics. This is mainly due to the similarity between their molecular structure and that of fat to some extent, as well as their ability to encapsulate and emulsify water and oil in food systems. This allows them to replace some fat in low-fat or fat-free foods, meeting people's demands for food taste while reducing the calorie content.

[0003] In the enzymatic hydrolysis of rice starch, the reaction temperature is a crucial parameter. The optimal reaction temperature for rice starch is around 55℃, which coincides with its gelatinization temperature. This places high demands on the reaction temperature, especially preventing it from becoming too high. Excessive temperature reduces enzymatic hydrolysis efficiency and, more importantly, causes gelatinization, resulting in the starch and protein becoming entangled and unable to separate, leading to waste. Conversely, lowering the temperature negatively impacts reaction efficiency. Therefore, temperature control is critical, especially during summer production when high ambient temperatures can easily cause the reaction temperature to rise. Typically, temperature control involves using a heat exchanger to bring the rice slurry to the set reaction temperature before it enters the reaction tank. The tank is then insulated with a hot water jacket to compensate for heat loss during the reaction. However, this method requires very precise temperature control; even slight errors can lead to excessively high temperatures. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a temperature-controlled enzymatic hydrolysis reaction device for rice starch lipid substitute.

[0005] The technical solution adopted to solve the above technical problems is: a temperature-controlled enzymatic hydrolysis reaction device for rice starch lipid substitute, including an outer shell assembly, an inner liner assembly fixedly connected to the inner side of the outer shell assembly, a steam heater installed on one side of the outer shell assembly, a fixed bracket fixedly connected to the top of the outer shell assembly, a sliding guide rail fixedly connected to the middle of one side of the fixed bracket, and a movable ladder slidably connected to the sliding guide rail.

[0006] Furthermore, the outer shell assembly includes a lower pot body and a half pot body. Several support pillars are fixedly connected to the bottom of the lower pot body. Circulation interfaces are provided on both sides of the middle of the lower pot body. The interior of the outer shell assembly is connected to a steam heater through the circulation interfaces. The bottom of the half pot body is fixedly connected to the top opening edge of the lower pot body. A sealing guide rail is fixedly connected at the connection between the lower pot body and the half pot body.

[0007] The above technical solution can achieve a tight seal between the lower pot body and the half pot body, preventing steam leakage and improving heating efficiency. At the same time, the setting of the circulation interface allows steam to circulate inside the outer shell assembly, evenly heating the rice slurry in the inner pot assembly, further improving the accuracy of temperature control. In addition, the fixed connection of the support column enhances the stability of the entire device, ensuring that it will not shake or tilt during the heating process, thereby ensuring the safe conduct of the enzymatic hydrolysis reaction.

[0008] Furthermore, a sealing shaft is fixedly connected to the top of the half-pot body, and the bottom end of the sealing shaft is fixedly connected to the inner liner assembly. Two sealing doors are slidably connected to the outer side of the top of the sealing shaft. The two sealing doors are symmetrically arranged, and the bottom ends of the two sealing doors are engaged and slidably connected to the sealing guide rail.

[0009] The above technical solution achieves a tight seal between the sealing door and the half-pot body, effectively preventing steam leakage and further improving heating efficiency and temperature control stability. Simultaneously, the symmetrical arrangement of the sealing door facilitates operation, and its sliding connection to the sealing guide rail makes opening and closing the door smoother, reducing resistance and friction during operation and extending the device's service life. Furthermore, the fixed connection between the sealing shaft and the inner liner assembly ensures the stability of the inner liner assembly, preventing it from shaking or deforming due to steam pressure changes during heating, thus guaranteeing the safety and stability of the enzymatic hydrolysis reaction.

[0010] Furthermore, a toothed groove is provided on the outer side of the bottom end of the sealing door, and a first motor is fixedly connected to the middle of both sides of the sealing guide rail. A first gear is fixedly connected to the power output end of the first motor, and one side of the first gear meshes with the toothed groove for transmission.

[0011] The above technical solution enables the automatic opening and closing of the sealed door. When the first motor starts, its power output drives the first gear to rotate. Since the first gear meshes with the tooth groove at the bottom of the sealed door, the rotation of the first gear causes the sealed door to slide along the sealing guide rail, thus automatically opening or closing the sealed door. This not only improves the convenience of operation but also further ensures the tightness of the sealed door when closed, effectively preventing steam leakage and improving the heating efficiency and temperature control stability of the device. At the same time, the automatic opening and closing design reduces the tediousness of manual operation and lowers the safety risks during operation.

[0012] Furthermore, the inner liner assembly includes a tank body, the top of which is fixedly connected to a sealing shaft, a feed door is installed on one side of the top of the tank body, and a discharge pipe is fixedly connected to the bottom of the tank body, the discharge pipe being fixedly connected through to the bottom of the lower pot body.

[0013] The above technical solution enables convenient feeding and discharging of rice starch. During the enzymatic hydrolysis reaction, rice starch is added to the tank through the feed door. After the reaction is complete, the rice starch and its enzymatic hydrolysis products can be smoothly discharged from the discharge pipe by opening the structure on the discharge pipe. This not only simplifies the operation process but also improves work efficiency. At the same time, because the discharge pipe is fixedly connected to the lower tank, the stability and continuity of the material during the transfer process are ensured, avoiding material waste and environmental pollution, and further enhancing the performance and practicality of the entire enzymatic hydrolysis reaction device.

[0014] Furthermore, a conical base is fixedly connected to one end of the discharge pipe inside the tank, and a hydraulic pusher is fixedly connected to the bottom end of the discharge pipe. The telescopic end of the hydraulic pusher is slidably connected to the discharge pipe. A push plate is fixedly connected to the telescopic end of the hydraulic pusher. Several top columns are fixedly connected to the end of the push plate away from the hydraulic pusher. The several top columns are arranged in a circular array around the center of the push plate. A triangular sealing cover is fixedly connected to the end of the several top columns away from the push plate. The several triangular sealing covers are slidably engaged with the conical base.

[0015] The above technical solution enables more efficient and stable control of the discharge of rice starch and its enzymatic hydrolysis products. During the discharge process, the extension and retraction of the hydraulic pusher causes the pusher plate and its top column and triangular sealing cover to slide along the conical base. Due to the sliding engagement design of the triangular sealing cover and the conical base, the tightness of the discharge port in both open and closed states is ensured, effectively preventing material leakage during the reaction process and improving the accuracy and stability of the device. At the same time, this design simplifies the discharge operation; the opening and closing of the discharge can be achieved simply by controlling the extension and retraction of the hydraulic pusher, which not only improves work efficiency but also reduces operational difficulty and labor costs. In addition, the circumferential array arrangement of the top column and triangular sealing cover makes the discharge more uniform, avoiding the accumulation and blockage of materials in the discharge pipe, further enhancing the performance and practicality of the entire enzymatic hydrolysis reaction device.

[0016] Furthermore, a drive shaft is rotatably connected to the middle of the tank body. The top end of the drive shaft is rotatably connected to the tank body and the half-pot body, and the bottom end of the drive shaft is rotatably connected to the conical base. A second motor is installed at the top end of the drive shaft. The second motor is fixedly connected to the fixed bracket, and the power output end of the second motor is fixedly connected to the drive shaft.

[0017] The above technical solution enables the stirring of materials within the tank. A second motor drives the transmission shaft to rotate. Since the transmission shaft is rotatably connected to the tank body, the half-pot body, and the conical base, its rotation can uniformly stir the materials within the tank. This stirring method not only increases the contact area between the materials and the enzymes, promoting the enzymatic hydrolysis reaction, but also ensures the uniform distribution of materials within the tank, avoiding uneven reaction caused by localized material accumulation. Furthermore, due to the stable connection between the transmission shaft and each component, no additional vibration or noise is generated during the stirring process, improving the overall efficiency and stability of the device.

[0018] Furthermore, a transmission box is fixedly connected to the top of the inner side of the tank, and the transmission box is rotatably connected to the transmission shaft. A stirring frame is rotatably connected to the bottom of the transmission box, and the middle of the bottom end of the stirring frame is rotatably connected to the transmission shaft. Several second stirring blades are fixedly connected to the inner sides of both ends of the stirring frame. Several fixing sleeves are fixedly connected to a section of the transmission shaft located inside the stirring frame. First stirring blades are symmetrically fixedly connected to the surface of the fixing sleeves. The first stirring blades and second stirring blades are arranged in a cross pattern.

[0019] The above technical solution further enhances the stirring effect. When the drive shaft rotates, the stirring frame rotates along with it via a through-rotation connection between the drive box and the drive shaft. The second stirring blades at both ends of the stirring frame and the first stirring blades on the drive shaft, due to their crisscrossing arrangement, create a more complex stirring flow field within the tank, resulting in more vigorous and uniform material flow. This design not only improves stirring efficiency but also allows the material to come into more complete contact with the enzyme during the enzymatic hydrolysis reaction, thereby improving the efficiency and uniformity of the reaction. Simultaneously, the stable connection between the fixed sleeve and the first stirring blades ensures that no additional vibration or noise is generated during stirring, further improving the overall efficiency and stability of the device.

[0020] Furthermore, a first gear ring is fixedly connected to a section of the drive shaft located inside the transmission box, and a second gear ring is fixedly connected to one end of the stirring frame connected to the transmission box. A driven gear is meshed and connected between the first gear ring and the second gear ring, and the driven gear is rotatably connected to the transmission box.

[0021] The above technical solution allows for further optimization of the transmission structure, enabling more precise stirring control. When the drive shaft rotates, the first gear ring rotates accordingly. Through the meshing of the driven gear and the second gear ring, the stirring frame rotates in the opposite direction. This reverse rotation design allows the first and second stirring blades to generate greater shear force during stirring, further improving the mixing uniformity and enzymatic hydrolysis efficiency. Simultaneously, the rotational connection between the driven gear and the transmission box ensures the stability of the stirring frame during rotation, avoiding uneven stirring caused by vibration or shaking. Furthermore, this reverse rotation stirring method promotes the circulation of materials within the tank, allowing for more thorough contact between the materials and the enzyme during the enzymatic hydrolysis reaction, thereby improving the overall efficiency and uniformity of the enzymatic hydrolysis reaction.

[0022] Furthermore, a connecting pipe is fixedly connected between the inlet and outlet ends of the steam heater and the circulation interface, and the steam heater forms a circulation structure with the inside of the outer shell assembly through the connecting pipe.

[0023] The above technical solution can further improve heating efficiency and thermal energy utilization. When the steam heater is working, steam enters the interior of the outer shell assembly through the connecting pipe, forming a circulating heating structure. This design allows heat to be distributed more evenly within the tank, avoiding localized overheating or uneven temperature. Simultaneously, the circulating heating structure accelerates heat transfer, improving heating efficiency and enabling rice starch to reach the required enzymatic hydrolysis temperature in a shorter time. Furthermore, because the steam heater and the interior of the outer shell assembly form a closed circulation structure, heat loss is effectively reduced, improving thermal energy utilization and thus lowering energy consumption, making it more energy-efficient and environmentally friendly.

[0024] The beneficial effects of this invention are as follows: 1. This invention, through the optimized structural design of the outer shell and inner liner components, forms a stable and efficient heating environment, ensuring that the enzymatic hydrolysis reaction can be carried out at a precisely controlled temperature, avoiding the impact of temperature fluctuations on reaction efficiency, effectively preventing starch gelatinization caused by excessively high temperatures, improving enzymatic hydrolysis efficiency and product quality. At the same time, the design of the circulating heating structure further improves the utilization rate of thermal energy and greatly reduces energy consumption.

[0025] 2. This invention, through the innovative design of the stirring structure, including the cross arrangement of the drive shaft, stirring frame, first stirring blade and second stirring blade, and the stirring method of counter-rotation, makes the mixing of materials in the tank more uniform, improves the efficiency and uniformity of the enzymatic hydrolysis reaction. At the same time, this design also reduces the difficulty of operation and labor costs, and improves work efficiency.

[0026] 3. Through the ingenious design of components such as sliding guide rails, movable ladders, and sealed doors, this invention not only achieves convenient operation and maintenance of the device, but also ensures the sealing and safety of the device during the heating process, effectively preventing steam leakage and improving heating efficiency and temperature control stability.

[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0030] like Figures 1 to 9As shown, this embodiment of a temperature-controlled enzymatic hydrolysis device for rice starch lipid substitute includes an outer shell assembly 1, an inner liner assembly 2 fixedly connected to the inner side of the outer shell assembly 1, a steam heater 3 installed on one side of the outer shell assembly 1, a fixed bracket 4 fixedly connected to the top of the outer shell assembly 1, a sliding guide rail 5 fixedly connected to the middle of one side of the fixed bracket 4, and a movable ladder 6 slidably connected to the sliding guide rail 5. The space between the outer shell assembly 1 and the inner liner assembly 2 is hollow, serving as a heat-insulating heating layer, effectively reducing heat loss and improving heating efficiency. Simultaneously, the design of the heat-insulating heating layer ensures a moderate temperature on the outer surface of the device, avoiding the risk of burns due to high temperatures, further enhancing the safety and practicality of the device. The inner liner assembly 2 is made of corrosion-resistant and easy-to-clean materials, ensuring that its performance will not degrade due to material residue or corrosion during long-term use, extending the device's service life. The steam heater 3 adopts a high-efficiency and energy-saving design, capable of rapidly heating and stably maintaining the required temperature, ensuring the smooth progress of the enzymatic hydrolysis reaction. The fixed bracket 4 not only provides stable support for the sliding guide rail 5 and the movable ladder 6 but also ensures the stability of the entire device during the heating process. The design of the sliding guide rail 5 and the movable ladder 6 allows operators to easily access the interior of the device for maintenance and repair, improving work efficiency and ease of operation.

[0031] like Figures 1 to 5 As shown, the outer shell assembly 1 includes a lower pot body 101 and a half-pot body 102. Several support pillars 106 are fixedly connected to the bottom perimeter of the lower pot body 101. Circulation interfaces 105 are provided on both sides of the middle section of the lower pot body 101. The interior of the outer shell assembly 1 is connected to the steam heater 3 through the circulation interfaces 105. The bottom of the half-pot body 102 is fixedly connected to the top opening edge of the lower pot body 101. A sealing guide rail 103 is fixedly connected at the connection between the lower pot body 101 and the half-pot body 102. A sealing door 104 is slidably connected to one side of the sealing guide rail 103. The cooperative design of the sealing guide rail 103 and the sealing door 104 ensures the sealing performance of the device during the heating process, effectively preventing steam leakage and improving heating efficiency and temperature control stability. Simultaneously, the sliding design of the sealing guide rail 103 allows the sealing door 104 to be easily opened and closed, facilitating the loading and unloading of materials by operators and improving operational convenience.

[0032] like Figures 1 to 5As shown, a sealing shaft 107 is fixedly connected to the top of the half-pot body 102, and the bottom end of the sealing shaft 107 is fixedly connected to the inner liner assembly 2. Two sealing doors 104 are slidably connected to the outer side of the top of the sealing shaft 107. The two sealing doors 104 are symmetrically arranged, and the bottom ends of the two sealing doors 104 are engaged and slidably connected to the sealing guide rail 103, which can realize the automatic opening and closing control of the sealing doors 104. When the first motor 109 is started, it drives the first gear 110 to rotate. Since the first gear 110 is engaged with the tooth groove 108 on the sealing door 104, the rotation of the first gear 110 will drive the sealing door 104 to slide along the sealing guide rail 103, thereby realizing the automatic opening or closing of the sealing door.

[0033] like Figures 1 to 5 As shown, a toothed groove 108 is provided on the outer side of the bottom end of the sealing door 104. A first motor 109 is fixedly connected to the middle of both sides of the sealing guide rail 103. A first gear 110 is fixedly connected to the power output end of the first motor 109. One side of the first gear 110 meshes with the toothed groove 108 for transmission. Figure 4 As shown, a connecting pipe 301 is fixedly connected between the inlet and outlet ends of the steam heater 3 and the circulation interface 105. The steam heater 3 forms a circulation structure with the interior of the outer shell assembly 1 through the connecting pipe 301. The inner liner assembly 2 includes a tank 201. The top of the tank 201 is fixedly connected to the sealing shaft 107. A feed door 202 is installed on one side of the top of the tank 201. A discharge pipe 203 is fixedly connected to the bottom of the tank 201. The discharge pipe 203 is fixedly connected through the bottom of the lower pot body 101. The design of the discharge pipe 203 not only ensures the smooth discharge of materials after the enzymatic reaction is completed, but also achieves precise control of the discharge process through its ingenious structural design and cooperation with components such as the hydraulic push column 207, the push plate 206, and the triangular sealing cover 208. This avoids leakage and accumulation of materials during the discharge process, further improving the performance and practicality of the entire device.

[0034] like Figures 6 to 7As shown, a conical base 204 is fixedly connected to one end of the discharge pipe 203 inside the tank 201. A hydraulic pusher 207 is fixedly connected to the bottom end of the discharge pipe 203. The telescopic end of the hydraulic pusher 207 is slidably connected to the discharge pipe 203. A push plate 206 is fixedly connected to the telescopic end of the hydraulic pusher 207. Several top columns 205 are fixedly connected to the end of the push plate 206 away from the hydraulic pusher 207. The top columns 205 are arranged in a circular array around the center of the push plate 206. A triangular sealing cover 208 is fixedly connected to the end of the top columns 205 away from the push plate 206. The triangular sealing covers 208 are slidably engaged with the conical base 204. This slidable engagement design not only enhances the sealing of the discharge port but also makes the discharge operation smoother. During the discharge process, the telescopic movement of the hydraulic pusher pushes the push plate and top columns to move, thereby causing the triangular sealing covers to slide open along the conical base, allowing the material to be discharged smoothly.

[0035] like Figures 6 to 7 As shown, a drive shaft 210 is rotatably connected to the middle of the tank 201. The top end of the drive shaft 210 is rotatably connected to the tank 201 and the half-pot 102, while the bottom end is rotatably connected to the conical base 204. A second motor 215 is mounted on the top end of the drive shaft 210 and is fixedly connected to the fixed bracket 4. The power output end of the second motor 215 is fixedly connected to the drive shaft 210. The rotation of the drive shaft 210 not only drives the stirring of the material but also achieves precise control of the entire enzymatic hydrolysis process through its precise transmission design. Specifically, when the second motor 215 starts, its powerful force is transmitted to the drive shaft 210 through the fixed connection, enabling the drive shaft 210 to rotate stably and smoothly within the tank 201, the half-pot 102, and the conical base 204. This rotation not only promotes full contact between the material and the enzyme, improving the enzymatic hydrolysis efficiency, but also ensures the stability and reliability of the entire stirring process through the close cooperation between the drive shaft 210 and various components.

[0036] like Figures 8 to 9As shown, a transmission box 209 is fixedly connected to the top inner side of the tank 201. The transmission box 209 is rotatably connected to the transmission shaft 210. A stirring frame 211 is rotatably connected to the bottom of the transmission box 209. The middle of the bottom end of the stirring frame 211 is rotatably connected to the transmission shaft 210. Several second stirring blades 214 are fixedly connected to the inner sides of both ends of the stirring frame 211. Several fixing sleeves 213 are fixedly connected to a section of the transmission shaft 210 located inside the stirring frame 211. First stirring blades 212 are symmetrically fixedly connected to the surface of the fixing sleeves 213. The first stirring blades 212 and the second stirring blades 214 are arranged in a cross pattern. This cross pattern design not only makes the stirring more uniform but also reduces dead corners in the stirring process to a certain extent, thus improving the stirring efficiency. At the same time, the materials of the first stirring blades 212 and the second stirring blades 214 have been carefully selected, possessing excellent corrosion resistance and wear resistance, which can maintain a stable stirring effect during long-term use and extend the service life of the device.

[0037] like Figures 8 to 9 As shown, a first gear ring 216 is fixedly connected to one end of the drive shaft 210 located inside the transmission box 209, and a second gear ring 218 is fixedly connected to the end of the stirring frame 211 connected to the transmission box 209. A driven gear 217 meshes and drives between the first gear ring 216 and the second gear ring 218. The driven gear 217 is rotatably connected to the transmission box 209. This precise transmission design ensures that the stirring frame 211 can maintain a stable operating state during rotation, avoiding uneven stirring caused by vibration or shaking.

[0038] The working principle of this embodiment is as follows: When using it, first add rice starch, the enzymes required for enzymatic hydrolysis, and other auxiliary materials into the tank 201 through the feed door 202, and then close the feed door 202.

[0039] At this time, the first motor 109 is started, and its power output drives the first gear 110 to rotate. Since the first gear 110 is meshed with the tooth groove 108 at the bottom of the sealing door 104, the rotation of the first gear 110 will drive the sealing door 104 to slide along the sealing guide rail 103, realizing the automatic opening or closing of the sealing door 104. This not only improves the convenience of operation, but also further ensures the tightness of the sealing door 104 when closed, effectively preventing steam leakage, improving the heating efficiency and temperature control stability of the device. At the same time, the automatic switch design also reduces the tedium of manual operation and lowers the safety risks during operation. Start the steam heater 3. Steam enters the shell assembly 1 through the connecting pipe 301, forming a circulating heating structure to uniformly heat the material in the tank 201, so that it reaches the required enzymatic hydrolysis temperature.

[0040] Simultaneously, the second motor 215 is started, which drives the transmission shaft 210 to rotate. The rotation of the transmission shaft 210 drives the stirring frame 211 to rotate through the transmission box 209. The second stirring blades 214 at both ends of the stirring frame 211 and the first stirring blades 212 on the transmission shaft 210, due to their cross arrangement, can form a more complex stirring flow field in the tank 201, making the flow of materials in the tank 201 more intense and uniform, thus promoting the enzymatic hydrolysis reaction.

[0041] When material needs to be discharged, the hydraulic pusher 207 is activated. The extension and retraction of the hydraulic pusher 207 causes the pusher plate 206, its top column 205, and the triangular sealing cover 208 to slide along the conical base 204. Due to the sliding engagement design between the triangular sealing cover 208 and the conical base 204, the tightness of the discharge port in the open state is ensured, effectively preventing material leakage during the discharge process. At the same time, this design simplifies the discharge operation; opening and closing the discharge port can be achieved simply by controlling the extension and retraction of the hydraulic pusher 207, thus improving work efficiency.

[0042] Furthermore, during the use of the device, it can be conveniently operated and maintained via the sliding guide rail 5 and the movable ladder 6. The temperature-controlled enzymatic hydrolysis reaction device for rice starch lipid substitute of the present invention has a compact structure and reasonable design, achieving efficient and stable enzymatic hydrolysis of rice starch, and has broad application prospects.
