Description

Technical Field

[0001] This utility model relates to the field of enzymatic hydrolysis technology, and in particular to a high-efficiency enzymatic hydrolysis reactor with an auxiliary stirring structure. Background Technology

[0002] In many fields such as biochemical engineering, food processing, and pharmaceuticals, enzymatic hydrolysis is an important biocatalytic method with significant advantages such as mild reaction conditions, high specificity, and high efficiency. It is widely used in the conversion and synthesis of various substances. As a key piece of equipment for realizing enzymatic hydrolysis, the performance of the enzymatic hydrolysis reactor directly affects the efficiency, product quality, and production cost of the enzymatic hydrolysis reaction.

[0003] Traditional enzymatic hydrolysis reactors are relatively simple in structure. In terms of stirring function, a single stirring rod is insufficient to create a sufficient and uniform stirring effect within the reactor. This results in incomplete mixing of powdered enzymes and reaction substrates, limited reaction contact area, and consequently, a lower enzymatic hydrolysis rate, longer reaction time, and reduced overall production efficiency. On the other hand, enzymatic hydrolysis is highly sensitive to temperature. Different enzymes have different activities and stability at different temperatures. Traditional reactors are prone to temperature rise during stirring, which can affect enzyme activity or even lead to enzyme inactivation due to excessively high or low local temperatures. This seriously affects the smooth progress of the enzymatic hydrolysis reaction and the quality of the product. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency enzymatic hydrolysis reactor with an auxiliary stirring structure, in order to solve the problem mentioned in the background art that traditional reactors are prone to temperature rise during stirring, which can affect enzyme activity due to excessively high or low local temperatures.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency enzymatic hydrolysis reactor with an auxiliary stirring structure, comprising an enzyme generating cylinder, a top cover at the top of the enzyme generating cylinder, a stirring mechanism at the top of the top cover, a motor fixedly mounted on the top of the top cover, a rotating rod fixedly mounted on the output shaft of the motor, a first stirring rod and a second stirring rod rotatably mounted inside the enzyme generating cylinder for mixing powdered enzymes, and both the first stirring rod and the second stirring rod are fixedly connected to the rotating rod, the first stirring rod comprising an outer tube mounted on one end of the motor output shaft, an inner tube fixedly mounted inside the outer tube, and a spiral condenser tube fixedly mounted between the outer tube and the inner tube, and multiple cooling water pipes disposed inside the inner tube.

[0006] As a preferred embodiment of this utility model, the inner tube has multiple vent holes on its wall, and the inner wall of the inner tube is fitted with a membrane for breathability and waterproofing.

[0007] As a preferred embodiment of this utility model, a fixing rod for supporting and reinforcing the pipe is installed in the middle of the inner tube, and the cooling water pipe is fixedly connected to the fixing rod through multiple connecting rods.

[0008] As a preferred embodiment of this utility model, the enzyme generating cylinder is provided with a cleaning mechanism inside. The cleaning mechanism includes a scraper installed on the output shaft of a motor. A fixing ring is fixedly installed on the output shaft of the motor. The scraper is fixedly installed on the outer surface of the fixing ring and slides on the inner wall of the enzyme generating cylinder.

[0009] As a preferred embodiment of this utility model, a gas collecting ring is fixedly installed inside the enzyme generating cylinder, and the gas collecting ring is connected to the fixed ring. An air pump is fixedly installed at the top of the top cover, and the output end of the air pump is connected to the gas collecting ring. The scraper has multiple spray holes on its surface near the enzyme generating cylinder for cleaning the inner wall of the enzyme generating cylinder. A filter box for filtering gas is connected to the top of the top cover.

[0010] As a preferred embodiment of this utility model, a filter plate is fixedly installed inside the scraper, and multiple compression chambers are fixedly installed on the surface of the filter plate. A one-way valve is provided between the gas output end of the compression chamber and the spray hole.

[0011] As a preferred embodiment of the present invention, the enzyme generating cylinder is provided with an auxiliary mechanism inside. The auxiliary mechanism includes a base fixedly installed on the bottom wall of the enzyme generating cylinder. A vibrating rotor is fixedly installed at one end of the first stirring rod and the second stirring rod. A magnetic ring and an electromagnetic coil for adjusting the vibration frequency of the vibrating rotor are fixedly installed inside the base.

[0012] As a preferred embodiment of this utility model, the top of the top cover is connected to a feed inlet, and the top of the top cover is provided with a monitoring box for monitoring enzymatic hydrolysis reaction data.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This invention forms a multi-rod stirring structure by setting a first stirring rod and a second stirring rod driven by a motor inside the enzyme generating cylinder. This method can create a more complex and comprehensive stirring flow field inside the enzyme generating cylinder, allowing the powdered enzyme and the reaction substrate to be mixed more fully and evenly, greatly increasing the reaction contact area. At the same time, through the spiral condenser tube set between the outer and inner tubes and the multiple cooling water pipes inside the inner tube, the temperature of the reaction system can be precisely adjusted according to the strict temperature requirements of the enzymatic hydrolysis reaction, avoiding excessive local temperature that could lead to enzyme inactivation, and ensuring that the enzyme maintains high activity and stably carries out the catalytic reaction under suitable temperature conditions.

[0015] 2. This utility model uses a motor-driven scraper to slide along the inner wall of the enzyme generator, which can directly scrape off the residual reaction products and raw materials on the inner wall, effectively preventing the accumulation of residues from causing cross-contamination in subsequent reactions and corrosion of the reactor. In addition, the air pump delivers gas to the gas collecting ring, and then sprays it out through the nozzles on the scraper to form a high-pressure airflow, which can further flush the inner wall and blow off the fine residues that are difficult to remove by the scraper, achieving a more thorough cleaning.

[0016] 3. This utility model uses a vibrating rotor to form a magnetically coupled vibration module under the action of a magnetic ring and an electromagnetic coil. This causes the vibrating rotor to vibrate continuously, further enhancing the stirring effect, promoting the relative movement between reactants, accelerating the enzymatic hydrolysis process, thereby significantly improving the efficiency of the enzymatic hydrolysis reaction, shortening the reaction time, and reducing production costs.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-6 This utility model provides a high-efficiency enzymatic hydrolysis reactor with an auxiliary stirring structure, including an enzyme generating cylinder 1, a top cover 2 at the top of the enzyme generating cylinder 1, and a stirring mechanism 5 at the top of the top cover 2. The stirring mechanism 5 includes a motor 51 fixedly installed at the top of the top cover 2, and a rotating rod 52 fixedly installed on the output shaft of the motor 51. A first stirring rod 53 and a second stirring rod 54 for mixing powdered enzymes are rotatably installed inside the enzyme generating cylinder 1, and both the first stirring rod 53 and the second stirring rod 54 are fixedly connected to the rotating rod 52. The first stirring rod 53 includes an outer tube 531 installed at one end of the output shaft of the motor 51, an inner tube 532 fixedly installed inside the outer tube 531, and a spiral condenser tube 533 fixedly installed between the outer tube 531 and the inner tube 532. Multiple cooling water pipes 536 are arranged inside the inner tube 532.

[0026] The motor 51 drives the rotating rod 52 to rotate, which in turn drives the first stirring rod 53 and the second stirring rod 54, which are fixedly connected to the rotating rod 52, to rotate inside the enzyme generating cylinder 1. The dual stirring rod design increases the stirring area and stirring intensity, realizing the stirring and mixing of powdered enzyme and reaction substrate, increasing the reaction contact area, and accelerating the enzymatic hydrolysis process. The first stirring rod 53 adopts a special structure, with a spiral condenser 533 set between the outer tube 531 and the inner tube 532, and multiple cooling water pipes 536 set inside the inner tube 532. This allows for the regulation of the reaction system temperature, precise control of the reaction temperature, providing a suitable reaction environment for the enzyme, ensuring the enzyme activity and stability, and improving reaction efficiency and product quality.

[0027] In some embodiments, the inner tube 532 has a plurality of vent holes 534 on its wall, and the inner wall of the inner tube 532 is fitted with a membrane 535 for breathability and waterproofing.

[0028] During the reaction, the cold air generated by the cooling water pipe 536 can be discharged through the exhaust port 534 and the breathable and waterproof membrane 535, thereby cooling the enzymatic hydrolysis reaction. At the same time, the breathable and waterproof membrane 535 can prevent liquid leakage, avoid interference with the enzymatic hydrolysis reaction, and ensure the sealing and stability of the reaction system.

[0029] In some embodiments, a fixing rod 537 for supporting and reinforcing the pipe is installed at the middle position of the inner tube 532, and the cooling water pipe 536 is fixedly connected to the fixing rod 537 through a plurality of connecting rods 538.

[0030] The fixing rod 537 serves to support and reinforce the pipe, keeping the cooling water pipe 536 in a stable position within the inner pipe 532. This enhances the stability of the cooling water pipe 536 within the inner pipe 532, preventing it from shaking or shifting during stirring and ensuring consistent and reliable cooling performance.

[0031] In some embodiments, the enzyme generating cylinder 1 is provided with a cleaning mechanism 6 inside. The cleaning mechanism 6 includes a scraper 64 installed on the output shaft of the motor 51. A fixing ring 63 is fixedly installed on the output shaft of the motor 51. The scraper 64 is fixedly installed on the outer surface of the fixing ring 63 and slides on the inner wall of the enzyme generating cylinder 1.

[0032] When the motor 51 rotates, it drives the fixed ring 63 to rotate, and the fixed ring 63 drives the scraper 64 to rotate together. The scraper 64 slides on the inner wall of the enzyme generating cylinder 1, thereby scraping off the residue on the inner wall, cleaning the inner wall of the enzyme generating cylinder 1, and timely scraping off the residue on the inner wall to avoid the accumulation of residue and cross-contamination of subsequent reactions, thus ensuring the purity and quality of the reaction product.

[0033] In some embodiments, a gas collecting ring 62 is fixedly installed inside the enzyme generating cylinder 1, and the gas collecting ring 62 is connected to the fixing ring 63. An air pump 61 is fixedly installed at the top of the top cover 2, and the output end of the air pump 61 is connected to the gas collecting ring 62. A scraper 64 has multiple spray holes 68 for cleaning the inner wall of the enzyme generating cylinder 1 near its surface. A filter box 69 for filtering gas is connected to the top of the top cover 2.

[0034] The gas pump 61 pumps gas into the gas collecting ring 62, and then delivers the gas to the nozzles 68 on the surface of the scraper 64 through the channel connected to the gas collecting ring 62, thereby achieving air jet cleaning of the inner wall of the enzyme generating cylinder 1. The combination of air jet cleaning and mechanical scraping by the scraper 64 can more thoroughly remove the residue on the inner wall of the enzyme generating cylinder 1 and improve the cleaning effect. The filter box 69 filters the gas to ensure that the gas entering the reactor is clean and to avoid impurities from having an adverse effect on the reaction.

[0035] In some embodiments, a filter plate 65 is fixedly installed inside the scraper 64, and a plurality of compression boxes 66 are fixedly installed on the surface of the filter plate 65. A one-way valve 67 is provided between the gas output end of the compression box 66 and the nozzle 68.

[0036] The compressed gas is ejected from the nozzle 68 through the one-way valve 67, which increases the pressure of the ejected gas and enhances the cleaning effect of the jet. It can more effectively flush away the residue on the inner wall. The one-way valve 67 ensures that the gas can only flow in one direction, ensuring the effective utilization of the compressed gas and the stability of the jet.

[0037] In some embodiments, an auxiliary mechanism 7 is provided inside the enzyme generating cylinder 1. The auxiliary mechanism 7 includes a base 71 fixedly installed on the bottom wall of the enzyme generating cylinder 1. A vibrating rotor 72 is fixedly installed at one end of the first stirring rod 53 and the second stirring rod 54. A magnetic ring 73 and an electromagnetic coil 74 for adjusting the vibration frequency of the vibrating rotor 72 are fixedly installed inside the base 71.

[0038] In this process, by adjusting the current of the electromagnetic coil 74, the magnetic field strength is changed, thereby adjusting the vibration frequency of the vibrating rotor 72, forming a magnetically coupled vibration module, which makes the vibrating rotor 72 vibrate continuously, further enhancing the stirring effect, making the stirring more thorough, accelerating the enzymatic hydrolysis process, and significantly improving the reaction efficiency.

[0039] In some embodiments, the top of the top cover 2 is connected to a feed inlet 3, and the top of the top cover 2 is provided with a monitoring box 4 for monitoring enzymatic hydrolysis reaction data.

[0040] The top cover 2 has a feed inlet 3 connected to the top for adding reaction raw materials into the enzyme generating cylinder 1; the monitoring box 4 can acquire reaction data in real time, and the operator can adjust the reaction conditions in a timely manner according to the monitoring results to ensure that the reaction is carried out under the best conditions, thereby improving the stability of the reaction and the quality of the product.

[0041] Working principle: The motor 51 drives the rotating rod 52 to rotate, which in turn drives the first stirring rod 53 and the second stirring rod 54, which are fixedly connected to the rotating rod 52, to rotate inside the enzyme generating cylinder 1. The double stirring rod design increases the stirring area and stirring intensity, realizing the stirring and mixing of powdered enzyme and reaction substrate, increasing the reaction contact area, and accelerating the enzymatic hydrolysis process. During the stirring process, the spiral condenser 533 set between the outer tube 531 and the inner tube 532, as well as the multiple cooling water pipes 536 inside the inner tube 532, can precisely adjust the temperature of the reaction system according to the strict temperature requirements of the enzymatic hydrolysis reaction, avoiding excessive local temperature that could lead to enzyme inactivation, and ensuring that the enzyme maintains high activity and stably carries out the catalytic reaction under suitable temperature conditions.

[0042] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
