Description

Technical Field

[0001] This application relates to the field of rice bran oil processing technology, and more specifically, to an intelligent enzymatic deacidification system for rice bran oil. Background Technology

[0002] Deacidification of rice bran oil is a key step in the refining process, aimed at reducing the content of free fatty acids (FFA) and improving the quality and stability of the oil.

[0003] In existing technologies, commonly used methods for deacidifying rice bran oil include chemical alkaline refining, which neutralizes free fatty acids with alkali, and physical refining, which removes FFA through steam distillation under high temperature and high vacuum conditions. However, chemical alkaline refining generates a large amount of wastewater, while physical refining destroys nutrients such as oryzanol. Therefore, biotechnological deacidification methods (enzymatic deacidification) have been optimized. These methods utilize lipases to catalyze the reaction between FFA and glycerol / monoglycerides to generate glycerides, thereby reducing the free fatty acid content. This method produces few byproducts and causes minimal damage to nutrients, making it suitable for the production and processing of high-quality rice bran oil. However, when using enzymatic deacidification, the activity of the catalytic enzyme decreases with increasing usage time. To reduce production costs, the catalytic enzyme is usually reused. Therefore, the recycled catalytic enzyme slows down its catalytic rate of fatty acid catalysis with each reuse, resulting in different deacidification times for different batches of rice bran oil. This makes it difficult to control the deacidification process of different batches of rice bran oil within the same time range, increasing the management difficulty of rice bran oil deacidification.

[0004] Therefore, it is necessary for the inventors to design a new intelligent enzymatic deacidification system for rice bran oil to overcome the above problems. Summary of the Invention

[0005] The main objective of this application is to provide an intelligent enzymatic deacidification system for rice bran oil to solve the problem of difficulty in controlling the deacidification processing time of different batches of rice bran oil in related technologies.

[0006] To achieve the above objectives, this application provides an intelligent enzymatic deacidification system for rice bran oil, comprising: A reaction chamber, wherein a circulation belt assembly is fixedly installed in the reaction chamber, and a plurality of dense mesh frames for placing catalytic enzymes are fixedly installed on the circulation belt assembly, and at least two of the dense mesh frames are immersed in rice bran oil in the reaction chamber; The loading and unloading assembly is used to install or remove the dense mesh frame onto the circulating belt assembly; A stirring assembly for stirring the rice bran oil in the reaction chamber; Heating components are used to heat the rice bran oil in the reaction chamber; It also includes a concentration monitoring device, a temperature monitoring device, and a controller. The concentration monitoring device and the temperature monitoring device are both immersed in rice bran oil in the reaction chamber. The concentration monitoring device and the temperature monitoring device are both electrically connected to the controller. The controller controls the movement of the circulation belt assembly based on the fatty acid content monitored by the concentration monitoring device, thereby causing the dense mesh frame to be immersed in or exposed above the surface of the rice bran oil. The controller also controls the power of the heating component based on the temperature of the rice bran oil measured by the temperature monitoring device.

[0007] Optionally, the circulating belt assembly includes a circulating belt body, a driving wheel, and a driven wheel. The driving wheel is fixedly connected to the shaft of an external rotating output device, the driven wheel is rotatably connected inside the reaction chamber, and the circulating belt body is connected for transmission between the driving wheel and the driven wheel.

The magnetic suction assembly is fixedly disposed between the circulating belt body and the mesh frame. The operating window is opened on the side wall of the reaction chamber. The external robotic arm installs and removes the mesh frame through the operating window.

[0009] Optionally, the controller controls the movement of the circulating belt assembly based on the fatty acid content monitored by the concentration monitoring device, thereby causing the dense mesh frame to be immersed in or exposed above the rice bran oil surface, including: The controller stores a standard concentration curve of fatty acids in rice bran oil under the action of a normally active catalytic enzyme. The concentration monitoring device monitors the real-time concentration of fatty acids in the reaction chamber and transmits the data to the controller. The controller presets a maximum threshold concentration curve of fatty acids under the action of a low-activity catalytic enzyme. The controller is used to determine whether the real-time concentration curve obtained based on the real-time concentration of fatty acids in the reaction chamber is between the maximum threshold concentration curve and the standard concentration curve. If it deviates, the controller controls the circulation belt assembly to send a dense mesh frame containing uncatalyzed catalytic enzyme into the rice bran oil and to transport a dense mesh frame containing the catalytic enzyme with the longest catalytic time out of the rice bran oil.

[0010] Optionally, the controller further controls the power of the heating component based on the temperature of the rice bran oil measured by the temperature monitoring device, including: The controller stores a standard temperature range for the catalytic enzyme to operate. The temperature monitoring component monitors the real-time temperature of the rice bran oil in the reaction chamber and uploads it to the controller. The controller determines the relationship between the real-time temperature and the standard temperature range. If the real-time temperature is higher than the standard temperature range, the controller controls the power of the heating component to decrease. If the real-time temperature is lower than the standard temperature range, the controller controls the power of the heating component to increase.

This ensures that the processing time of each batch of rice bran oil in the deacidification process is relatively close. At the same time, intelligent control is achieved through controllers, temperature monitoring devices, and concentration monitoring devices, which greatly improves the accuracy of control and allows for better control of the rice bran oil deacidification processing time.

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] like Figures 1 to 5 As shown, an intelligent enzymatic deacidification system for rice bran oil includes: a reaction chamber 1, in which a circulation belt assembly 2 is fixedly installed, and multiple fine mesh frames 3 for placing catalytic enzymes are fixedly installed on the circulation belt assembly 2, with at least two of the fine mesh frames 3 immersed in the rice bran oil in the reaction chamber 1; a loading and unloading assembly for installing or removing the fine mesh frames 3 from the circulation belt assembly 2; a stirring assembly for stirring the rice bran oil in the reaction chamber 1; a heating assembly for heating the rice bran oil in the reaction chamber 1; and further includes a concentration monitoring device, a temperature monitoring device, and a controller. The concentration monitoring device and the temperature monitoring device are both immersed in the rice bran oil in the reaction chamber 1, and are electrically connected to the controller. The controller controls the movement of the circulation belt assembly 2 based on the fatty acid content monitored by the concentration monitoring device, thereby causing the fine mesh frames 3 to be immersed in or exposed above the surface of the rice bran oil. The controller also controls the power of the heating assembly based on the temperature of the rice bran oil measured by the temperature monitoring device.

[0026] Specifically, multiple dense mesh frames 3 are set on the circulation belt assembly 2, each containing enzyme particles that decompose fatty acids. During operation, the circulation belt assembly 2 sequentially immerses these mesh frames 3 into rice bran oil. The mesh frames 3 that are first immersed in the rice bran oil experience a decrease in activity after prolonged catalysis, and are subsequently exposed above the surface of the rice bran oil as the circulation belt assembly 2 continues to operate. The deactivated enzymes are then removed from the circulation belt assembly 2 by the loading and unloading components, and new, unused enzymes are installed. When the circulation belt assembly 2 restarts, it is immersed in the rice bran oil again. Each time a new mesh frame 3 containing enzymes is immersed, one mesh frame 3 containing deactivated enzymes is exposed above the surface. This rotation method increases the average activity of the enzymes in all mesh frames 3, thereby accelerating the deacidification rate of this batch of rice bran oil and reducing the deacidification time. A stirring component is used to agitate the rice bran oil, ensuring it passes evenly through the mesh frames 3 and comes into contact with the enzyme particles within them. The heating element is used to maintain the temperature of rice bran oil within the high-activity temperature range of the catalytic enzyme, thereby improving catalytic efficiency.

[0027] The circulating belt assembly 2 includes a circulating belt body 201, a drive pulley 202, and a driven pulley 203. The drive pulley 202 is fixedly connected to the rotating shaft 4 of the external rotating output device. The driven pulley 203 is rotatably connected inside the reaction chamber 1. The circulating belt body 201 is connected for transmission between the drive pulley 202 and the driven pulley 203. Specifically, the external motor 8 drives the drive pulley 202 to rotate, which in turn drives the circulating belt body 201 to rotate, and the driven pulley 203 follows suit. The driven pulley 203 and the circulating belt body 201 can both be made of corrosion-resistant materials such as stainless steel, and should be replaced regularly to reduce the risk of rice bran oil contamination due to corrosion of the circulating belt body 201 and the driven pulley 203. It should be noted that the circulating belt assembly 2 in the figure is for illustration only. The actual shape and size of the circulating belt body 201, drive pulley 202, and driven pulley 203 should be selected according to actual needs, as long as the rotation of the drive pulley 202 can drive the circulating belt body 201 for transmission.

[0028] The loading and unloading assembly includes an external robotic arm, an operating window 5, and a magnetic suction assembly. The magnetic suction assembly is fixedly installed between the circulation belt body 201 and the mesh frame 3. The operating window 5 is located on the side wall of the reaction chamber 1. The external robotic arm installs and removes the mesh frame 3 through the operating window 5. Specifically, when the mesh frame 3 containing deactivated enzyme particles is exposed above the rice bran oil surface, the external robotic arm grasps the mesh frame 3 and pulls it forcefully to disconnect the magnetic suction assembly. At this point, the mesh frame 3 can be removed. Then, the robotic arm grasps the mesh frame 3 containing new, unused enzyme particles and reconnects it to the circulation belt body 201, reconnecting the magnetic suction assembly between them, thus replacing the mesh frame 3.

[0029] The controller controls the movement of the circulation belt assembly 2 based on the fatty acid content monitored by the concentration monitoring device, thereby causing the mesh frame 3 to be immersed in or exposed above the rice bran oil surface. The controller stores the standard concentration curve of fatty acids in rice bran oil under the action of normally active catalytic enzymes. The concentration monitoring device monitors the real-time concentration of fatty acids in the reaction chamber 1 and transmits the data to the controller. The controller presets the maximum threshold concentration curve of fatty acids under the action of low-activity catalytic enzymes. The controller is used to determine whether the real-time concentration curve obtained based on the real-time concentration of fatty acids in the reaction chamber 1 is between the maximum threshold concentration curve and the standard concentration curve. If it deviates, the controller controls the circulation belt assembly 2 to send the mesh frame 3 containing uncatalyzed catalytic enzymes into the rice bran oil and to transport the mesh frame 3 containing the catalytic enzyme with the longest catalytic time out of the rice bran oil.

[0030] Specifically, the average activity of all catalytic enzymes at 70% of their maximum activity can be used as the benchmark for plotting the standard concentration curve. That is, under this average activity level, the concentration-time relationship of fatty acids in rice bran oil during the period from which it decreases to a concentration meeting the production standard is plotted as the standard concentration curve. Then, the average activity of all catalytic enzymes at 60% of their maximum activity can be used as the benchmark for plotting the maximum threshold concentration curve. That is, under this average activity level, the maximum threshold concentration curve is plotted based on the concentration-time relationship of fatty acids in rice bran oil. The activities of the enzyme particles in the different mesh frames 3 immersed in rice bran oil vary. The enzyme particles that entered the rice bran oil last have an activity value of 100% of the maximum value, while the enzyme particles that entered the rice bran oil earliest have the lowest activity value, possibly 30% of the maximum value. At this point, the average activity of all enzymes may be 65% of the maximum value, between 60% and 70%, which is sufficient for normal catalytic reaction. The real-time concentration curve is located between the maximum threshold concentration curve and the standard concentration curve, and there is no need to introduce new enzymes. However, over time, the average activity of this batch of enzymes may decrease to 55%, at which point the catalytic rate slows down significantly. At the same reaction time, the fatty acid concentration is significantly higher than the fatty acid concentration in rice bran oil catalyzed by an activity value of 60%. This is reflected in the concentration curve as the real-time concentration curve deviates from the maximum threshold concentration curve. In this case, it is necessary to introduce new enzymes and remove the enzyme with the lowest activity to increase the average activity value of all enzymes, so that the average value returns to between 60% and 70% of the maximum value. At this point, the real-time concentration curve returns to the range between the maximum threshold concentration curve and the standard concentration curve. In this process, each batch of rice bran oil is catalyzed by an enzyme with an average activity level between 60% and 70%, which makes the reaction time of each batch relatively similar. If the most conservative longest reaction time is used as the time standard for switching rice bran oil batches, the effect of switching rice bran oil batches at regular intervals can be achieved, and the fatty acid concentration of each batch of rice bran oil can be reduced to the target range.

[0031] The controller also controls the power of the heating component based on the temperature of the rice bran oil measured by the temperature monitoring device. This includes storing a standard temperature range for the catalytic enzyme's operation in the controller, the temperature monitoring component monitoring the real-time temperature of the rice bran oil in the reaction chamber 1 and uploading it to the controller, and the controller determining the relationship between the real-time temperature and the standard temperature range. If the real-time temperature is higher than the standard temperature range, the controller reduces the power of the heating component; if the real-time temperature is lower than the standard temperature range, the controller increases the power of the heating component. Specifically, most studies show that the thermal stability of the lipase improves after immobilization, with the optimal temperature rising to 50–60℃. To protect the oryzanol in the rice bran oil, a mild condition of 50–55℃ is recommended to avoid high-temperature damage to nutrients. Therefore, the standard temperature range can be preset to 50–55℃. When the temperature monitoring device detects that the real-time temperature of the rice bran oil is below 50℃, the controller increases the heating power of the heating component to raise the temperature to within this range. Conversely, if the real-time temperature is higher than 55℃, the heating power is reduced to bring the temperature back to the standard temperature range.

[0032] Multiple magnetic attraction points 6 are fixedly provided on the circulating belt body 201, and a magnetic attraction part 7 that is magnetically connected to the magnetic attraction points 6 is fixedly provided on the dense mesh frame 3. Specifically, in this embodiment, the dense mesh frame 3 is fixedly installed by magnetic attraction. In addition, snap-fit ​​connection, bolt connection, and other methods can also be used to install the dense mesh frame 3. However, the magnetic attraction connection method is simple to install, facilitates the operation of the external robotic arm, and has a simple connection structure. If a complex connection structure is used, rust and metal ions may be released at the connection point, thus contaminating the rice bran oil. The simple and stable magnetic attraction connection can reduce such contamination.

[0033] The stirring assembly includes a motor 8 and a stirring shaft 9. The motor 8 is fixedly mounted on the top of the reaction chamber 1, and the stirring shaft 9 is rotatably mounted inside the reaction chamber 1. The stirring shaft 9 is fixedly connected to the output end of the motor 8, and multiple blades 10 are fixedly mounted on the stirring shaft 9. Specifically, in order to ensure that the rice bran oil in the reaction chamber 1 can react evenly with the catalytic enzyme particles in the dense mesh frame 3, the rice bran oil needs to be stirred. During operation, the motor 8 is mounted on an external support, and the output shaft of the motor 8 drives the stirring shaft 9 to rotate, which in turn drives the blades 10 to rotate, thus stirring the rice bran oil in the reaction chamber 1 and allowing it to react evenly with the catalytic enzyme particles in the dense mesh frame 3.

[0034] The heating assembly includes a heating element 11, which is fixedly mounted on the outer wall of the reaction chamber 1, which is made of stainless steel. Specifically, the heating element 11 heats the outer wall of the reaction chamber 1, which in turn conducts heat to the rice bran oil in the reaction chamber 1. The reaction chamber 1 is made of stainless steel because it has good thermal conductivity and good corrosion resistance. To prevent metal ion precipitation and contamination of the rice bran oil, surface treatment can be applied to the surface of the stainless steel reaction chamber 1, as well as to the surfaces of the stainless steel circulation belt body 201, driven wheel 203, and other structures. A food-grade PTFE (polytetrafluoroethylene) coating is applied to the surface to both prevent ion precipitation and reduce frictional wear.

[0035] The concentration monitoring device includes multiple concentration probes 12, which are fixedly installed at different depths in the reaction chamber 1. Specifically, the concentration probes 12 at different depths are used to detect the real-time concentration of fatty acids in rice bran oil at different locations, and the average value is taken as the standard value and output to the controller, thus reducing concentration errors.

[0036] The temperature monitoring device includes multiple temperature probes 13, which are fixedly installed at different depths in the reaction chamber 1. Specifically, the real-time temperature of fatty acids in rice bran oil at different locations is detected by the temperature probes 13 at different depths, and the average value is taken as a standard value and output to the controller, thus reducing temperature errors.

[0037] In this embodiment, a circulating belt assembly 2 is used to drive a dense mesh frame 3 containing catalytic enzyme particles to be sequentially immersed in rice bran oil. This ensures that the average activity of all catalytic enzyme particles immersed in the rice bran oil remains within a certain range, thereby making the processing time of each batch of rice bran oil in the deacidification process more similar. At the same time, intelligent control is achieved through a controller, temperature monitoring device, and concentration monitoring device, which greatly improves the accuracy of control and allows for better control of the rice bran oil deacidification processing time.

[0038] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
