Description

Technical Field

[0001] This utility model belongs to the technical field of caprylic / capric glyceride production equipment, specifically relating to an enzymatic synthesis reactor for caprylic / capric glyceride. Background Technology

[0002] Enzymatic synthesis of caprylic / capric glycerol is a green, environmentally friendly, and highly specific production process. Leveraging the high efficiency and specificity of enzyme catalysts, it enables the esterification reaction of caprylic / capric acid with glycerol under mild reaction conditions. However, this process is characterized by a long reaction time, typically requiring several hours or even tens of hours. During this period, frequent sampling and testing of the materials inside the reaction vessel are necessary to accurately control the reaction progress, monitor changes in enzyme activity, and ensure product quality.

[0003] Traditional reactor sampling methods mostly rely on manual sampling. This manual sampling process is cumbersome, requiring operators to perform a series of complex operations—opening the sampling port, extracting the sample, and closing the port—each time consuming significant time and effort. In the lengthy process of enzymatic synthesis, frequent manual sampling not only reduces operator efficiency but also hinders rapid, real-time sampling, making it impossible to obtain crucial data on the reaction process promptly and impeding precise control of the reaction progress. Delayed sampling leading to lag in reaction monitoring can result in over- or under-reaction, reducing the yield of caprylic / capric glycerol, lowering product quality, wasting raw materials, and significantly increasing production costs.

[0004] Furthermore, traditional sampling methods suffer from poor sample representativeness. During manual sampling, the difficulty in precisely controlling the sampling location and depth means that the sample may not accurately reflect the true state of the overall material within the reactor, leading to biased test results. Production decisions based on such sample test results may mislead the production process, affecting the stability and consistency of product quality and failing to meet the stringent quality control requirements of modern industrial production. Utility Model Content

[0005] To address the above problems, the purpose of this utility model is to provide a reaction vessel for the enzymatic synthesis of caprylic / capric glyceride, which solves the problems of long reaction time, frequent sampling required in the enzymatic synthesis of caprylic / capric glyceride, and the high safety risks, low sampling efficiency, and poor sample representativeness of traditional reaction vessels that use manual sampling.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an enzymatic synthesis reactor for caprylic / capric glycerol esters, comprising a reactor and a stirrer, characterized in that: a rapid sampling mechanism is provided on the top of the reactor via a top flange one and a top flange two, the rapid sampling mechanism comprising a pipeline system consisting of a Venturi tube, a suction tube, and a connecting tube, wherein the throat of the Venturi tube is connected to the top end of the suction tube, the bottom end of the suction tube is inserted into the interior of the reactor, the two ends of the Venturi tube are respectively connected to a nitrogen valve and a backwash valve, the backwash valve is connected to the interior of the reactor, the connecting tube is connected to a discharge tube, a discharge valve is installed on the discharge tube, and the nitrogen valve is connected to a nitrogen pipeline.

[0007] The beneficial effects of this invention are as follows: the reaction liquid can be safely and conveniently extracted by the flow of high-pressure nitrogen in the venturi tube, which effectively improves the convenience and safety of sampling; the reaction liquid can circulate in the rapid sampling mechanism and the reaction vessel to avoid cross-contamination of samples in the tube.

[0008] In order to solve the problems of sample residue, contamination and low sampling efficiency caused by unreasonable sampling tube structure in traditional sampling methods;

[0009] As a further improvement to the above technical solution: the bottom end of the lodging tube is inclined away from the Venturi tube.

[0010] The beneficial effects of this improvement are as follows: by designing the bottom end of the sampling tube to be inclined away from the Venturi tube, the sample is prevented from being retained in the pipeline, cross-contamination between different batches of samples is prevented, and the sample can be quickly discharged through the sampling tube under the negative pressure of the Venturi tube, thus improving the smoothness and reliability of the sampling operation.

[0011] To ensure the stability and hygiene of the rapid sampling facility;

[0012] As a further improvement to the above technical solution: the upper and lower sides of the backwash valve are connected to the connecting pipe and flange two by sanitary clamps, and flange two is connected to the tank top flange two by bolts.

[0013] The beneficial effects of this improvement are: the combination design of sanitary clamps and bolts not only ensures the sealing reliability of the connection, but also facilitates the disassembly and assembly of the backwash valve during maintenance, while meeting the sanitary requirements of the reactor in the enzymatic synthesis process.

[0014] To prevent external contaminants from entering the reaction system or internal materials from leaking out due to loose connections or leaks during the sampling process;

[0015] As a further improvement to the above technical solution: a flange is welded to the suction pipe, and the flange is bolted to the top flange of the tank.

[0016] The beneficial effects of this improvement are: by using welding and bolting, the suction pipe is mechanically fixed to the top of the reactor, and it is easy to disassemble and maintain, avoiding loosening of the connection due to vibration or pressure fluctuations.

[0017] To avoid poor sample representativeness due to improper sampling location;

[0018] As a further improvement to the above technical solution: the bottom end of the suction pipe is not higher than two-thirds of the depth of the reaction vessel.

[0019] The beneficial effects of this improvement are: by controlling the suction depth, it avoids direct contact with unreacted raw materials or precipitates that may exist at the bottom of the reactor, and can effectively collect the reaction liquid in a fully mixed state.

[0020] To avoid inaccurate or inefficient sampling due to unstable nitrogen supply pressure;

[0021] As a further improvement to the above technical solution: a pressure gauge is installed on the pipe on one side of the nitrogen valve.

[0022] The beneficial effects of this improvement are: by installing a pressure gauge on the pipeline on one side of the nitrogen valve, the nitrogen supply pressure can be monitored in real time, ensuring that the gas flow rate and pressure in the venturi tube are in a stable state.

[0023] To prevent the Venturi tube from becoming clogged due to impurities entering the bottom of the suction pipe;

[0024] As a further improvement to the above technical solution: a filter is installed at the bottom end of the suction pipe.

[0025] The beneficial effects of this improvement are: the filter can intercept solid particles or unreacted substances in the material, avoiding clogging of the venturi tube.

[0026] For easy maintenance of the filter;

[0027] As a further improvement to the above technical solution: the filter includes an upper connecting frame, which is fixed at the bottom end of the suction pipe. A long screw is inserted into the upper connecting frame, and a lower connecting frame is also inserted into the long screw. Nuts are threaded onto the long screws on both sides of the upper and lower connecting frames. A filter cartridge is clamped between the lower and upper connecting frames.

[0028] The benefits of this improvement are as follows: the clamp-on filter cartridge design allows the upper and lower connecting frames to be separated simply by loosening the nut when replacing the filter cartridge, without the need to disassemble the pipe connectors, which significantly improves maintenance efficiency.

[0029] To ensure the stability of the filter cartridge installation;

[0030] As a further improvement to the above technical solution: a positioning protrusion is formed on the opposite end face of the lower connecting frame and the upper connecting frame, and the end of the upper connecting frame is adapted to be inserted into the inner side of the positioning protrusion.

[0031] The beneficial effects of this improvement are as follows: by setting mutually cooperating positioning protrusions on the end faces of the upper and lower connecting frames, the end of the upper connecting frame can be precisely inserted into the inner side of the positioning protrusion of the lower connecting frame, forming a physical limiting and sealing surface. This structure achieves axial positioning and radial sealing between the upper and lower connecting frames, effectively preventing sealing failure caused by misalignment during filter cartridge clamping.

[0038] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0039] Example 1:

[0040] like Figure 1As shown in Figure 4: A reaction vessel for the enzymatic synthesis of caprylic / capric glycerol esters includes a reaction vessel 1 and a stirrer 2. The reaction vessel 1 is characterized by a rapid sampling mechanism 5 installed at its top via a top flange 3 and a top flange 2. The rapid sampling mechanism 5 comprises a pipeline system consisting of a Venturi tube 10, a suction pipe 8, and a connecting pipe 11. The throat of the Venturi tube 10 is connected to the top end of the suction pipe 8, and the bottom end of the suction pipe 8 is inserted into the interior of the reaction vessel 1. The two ends of the Venturi tube 10 are respectively connected to a nitrogen valve 16 and a backwash valve 15. The backwash valve 15 is connected to the interior of the reaction vessel 1. The connecting pipe 11 is connected to a sampling pipe 12, and a sampling valve 13 is installed on the sampling pipe 12. The nitrogen valve 16 is connected to a nitrogen pipeline. The reaction liquid is safely and conveniently extracted by the flow of high-pressure nitrogen in the Venturi tube, effectively improving the convenience and safety of sampling.The reaction solution can circulate within the rapid sampling mechanism and the reaction vessel to avoid cross-contamination of samples within the tube. The bottom end of the discharge tube 12 is inclined away from the Venturi tube 10. By designing the bottom end of the discharge tube 12 to be inclined away from the Venturi tube, sample retention in the pipeline is avoided, preventing cross-contamination between different batches of samples. This allows the sample to be quickly discharged through the discharge tube under the negative pressure of the Venturi tube, improving the smoothness and reliability of the sampling operation. The upper and lower sides of the backwash valve 15 are connected to the connecting pipe 11 and flange 7 via sanitary clamps 14. Flange 7 is bolted to the top flange 4 of the tank. The sanitary clamps 14 are connected to the bolts. The combined design of the connection ensures reliable sealing at the joints and facilitates disassembly and assembly of the backwash valve 15 during maintenance. It also meets the hygiene requirements of the reactor in the enzymatic synthesis process. A flange 6 is welded to the suction pipe 8, which is bolted to the top flange 3. This welding and bolting method achieves both mechanical fixation of the suction pipe to the top of the reactor and facilitates disassembly and maintenance, preventing loosening due to vibration or pressure fluctuations. The bottom of the suction pipe 8 is no higher than two-thirds of the depth of the reactor 1. By controlling the suction depth, direct contact with unreacted raw materials or sediments that may be present at the bottom of the reactor is avoided. It can effectively collect reaction liquid in a fully mixed state. A pressure gauge 17 is installed on the pipe on one side of the nitrogen valve 16. By setting the pressure gauge 17 on the pipe on one side of the nitrogen valve 16, the nitrogen supply pressure can be monitored in real time to ensure that the gas flow rate and pressure in the venturi tube are stable. A filter 9 is installed at the bottom end of the suction pipe 8. The filter 9 can intercept solid particles or unreacted substances in the material to avoid clogging the venturi tube. The filter 9 includes an upper connecting frame 91, which is fixed to the bottom end of the suction pipe 8. A long screw 92 is inserted into the upper connecting frame 91, and the long screw 92 is also inserted into a lower connecting frame 93. 1. Nuts are threaded onto the long screws 92 on both sides of the lower connecting frame 93. A filter cartridge 94 is clamped between the lower connecting frame 93 and the upper connecting frame 91. The clamp-on filter cartridge design allows the upper and lower connecting frames to be separated simply by loosening the nuts when replacing the filter cartridge, without disassembling the pipe connectors, significantly improving maintenance efficiency. Positioning protrusions 95 are formed on the facing end faces of both the lower connecting frame 93 and the upper connecting frame 91. The end of the upper connecting frame 91 is fitted into the inner side of the positioning protrusion 95. By setting mutually cooperating positioning protrusion structures on the end faces of the upper and lower connecting frames, the end of the upper connecting frame can be precisely inserted into the inner side of the positioning protrusion of the lower connecting frame, forming a physical limit and sealing surface.

[0041] The working principle of this technical solution is as follows: the conventional technologies required for the reaction, such as the jacket temperature control system, feed and discharge pipelines, and stirring mechanism in the reactor 1, all adopt existing mature technologies, and these systems will not cause structural conflicts with the rapid sampling mechanism 5.

[0042] When sampling is required, open the nitrogen valve 16 and ensure that the exhaust valve of the reactor 1 is properly opened to stably control the pressure inside the reactor. High-pressure nitrogen enters the venturi tube 10 through the nitrogen pipeline. Due to the narrow diameter of the throat of the venturi tube 10, the nitrogen flow rate increases and the pressure decreases according to the Venturi effect, thereby forming a negative pressure at the upper end of the suction pipe 8. Under the action of negative pressure, the reaction liquid in the reactor 1 is drawn up through the suction pipe 8. The bottom end of the suction pipe 8 is located at two-thirds of the depth of the reactor 1, which can effectively draw the reaction liquid located at the bottom of the tank and avoid drawing the deposited solid material too close to the bottom of the tank. At the same time, the filter 9 connected to the bottom end of the suction pipe 8 has a filter cartridge 94 that can filter large volume solid materials to prevent them from entering the suction pipe 8 and clogging the pipeline.

[0043] The pumped-up reaction liquid, along with nitrogen gas, enters the Venturi tube 10, then flows along the connecting pipe 11 and returns to the reactor 1 through the opened backwash valve 15. After the reaction liquid flows in the rapid sampling mechanism 5 for about ten seconds to replace the residual reaction liquid from the previous sampling, the sampling bag is placed at the end of the discharge pipe 12, and the discharge valve 13 is opened. The reaction liquid flowing in the lower part of the connecting pipe 11 can smoothly flow into the sampling bag through the discharge pipe 12. The reaction liquid in the first sampling bag is then poured back into the reactor. In step 1, the second sampling bag is then placed at the port of the sampling tube 12 to collect the reaction liquid again, thereby obtaining a pure reaction liquid sample for testing and analysis. That is, the first sampling liquid is used to flush the pipeline, and the second sampling is the valid sample. During the sampling process, the operator can observe the value of the pressure gauge 17 to intuitively understand the pressure in the rapid sampling mechanism 5, determine whether the suction tube 8 is blocked, and adjust the nitrogen inlet pressure as needed to ensure the smooth progress of the sampling process. After the sampling is completed, the sampling valve 13 and the nitrogen valve 16 are closed.

[0044] After the suction pipe 8 becomes blocked, the backwash valve 15 is closed and the nitrogen valve 16 is opened. At this time, nitrogen gas enters the reactor 1 directly through the suction pipe 8. The flushing action of high-pressure nitrogen gas can effectively remove the particulate matter attached to the inner wall of the suction pipe 8, keep the pipeline clean, and prepare for the next sampling.
