Description

Technical Field

[0001] This utility model relates to the field of lipase production technology, and more specifically, to a lipase reactor. Background Technology

[0002] With the continuous development of biotechnology, lipases, as important industrial enzymes, have been widely used in food, medicine, chemical industry, and environmental remediation. Lipases are enzymes that can catalyze the hydrolysis, esterification, and transesterification of lipid compounds. They exhibit high catalytic efficiency under mild conditions and high substrate selectivity, thus attracting much attention.

[0003] Temperature is a crucial factor in the lipase-catalyzed reaction process. Specifically, when the temperature is too high, the molecular structure of the lipase may undergo irreversible changes, leading to enzyme inactivation; while when the temperature is too low, although the enzyme structure may remain stable, its catalytic reaction rate will be significantly reduced, thus affecting production efficiency.

[0004] Currently, most lipase reactors use monolithic heating to control the temperature of the reaction system. While this method is simple in structure and easy to implement, it presents several problems in practice. First, because lipases are extremely sensitive to temperature, excessively high or low temperatures can lead to enzyme inactivation or a decrease in reaction rate. Monolithic heating makes precise temperature control difficult, thus limiting the optimization of reaction conditions. Second, monolithic heating has a large thermal inertia and a slow temperature adjustment response, which cannot meet the needs of certain special reactions requiring rapid temperature adjustments. Utility Model Content

[0028] Example 1

[0029] like Figures 1-4 As shown, this embodiment provides a lipase reactor, including a vessel body 1 and a vessel lid 2. The vessel lid 2 is movably connected to the vessel body 1. A mesh barrel 3 and a first stirring assembly are arranged inside the vessel body 1. A second stirring assembly is arranged on the vessel lid 2. The first stirring assembly is located outside the mesh barrel 3, and the second stirring assembly is located inside the mesh barrel 3. A temperature sensor 14 is arranged on the inner wall of the mesh barrel 3. Multiple heating units are evenly distributed along the axial direction on the outer wall of the vessel body 1.

[0030] Temperature sensor 14, in conjunction with the heating unit, effectively controls the temperature of the reaction process, ensuring high lipase activity and improving its catalytic effect at the reaction temperature. The first stirring component, the second stirring component, and the mesh tank 3 work together. The first stirring component stirs the liquid raw materials in the vessel 1, while the second stirring component stirs the lipase in the mesh tank 3, promoting contact between the lipase and the liquid raw materials and accelerating the flow rate of the liquid raw materials within the lipase, thereby increasing the catalytic reaction rate of the lipase, improving production efficiency, and ensuring product quality. Simultaneously, after the liquid raw materials enter the mesh tank 3 and react with the lipase, the completely reacted material can be filtered and separated by the mesh tank 3, improving the clarity and purity of the liquid. A discharge pipe is also provided at the bottom of the vessel 1, and a viewing window is provided on the side wall of the vessel 1.

[0031] In this specific embodiment, the mesh bucket 3 is detachably connected to the vessel body 1. A ring 12 is provided at the top of the mesh bucket 3, and the outer diameter of the ring 12 is the same as the outer diameter of the vessel body 1. Multiple connecting rods 13 are provided on the inner wall of the ring 12, and the other end of each connecting rod 13 is fixedly connected to the outer wall of the mesh bucket 3. In use, the ring 12 is placed on top of the vessel body 1, and the mesh bucket 3 is located inside the vessel body 1, facilitating the disassembly of the mesh bucket 3 for cleaning.

[0032] In a specific embodiment of this invention, the first stirring assembly includes a rotating rod 15 and multiple stirring rods 16 evenly distributed along the outer wall of the rotating rod 15. The stirring rods 16 are L-shaped. There are four stirring rods 16, evenly arranged circumferentially along the rotating rod 15, to improve the stirring effect on the liquid raw materials.

[0033] In a specific embodiment of this invention, a first motor 11 is provided at the bottom of the vessel body 1, and the output end of the first motor 11 is connected to the rotating rod 15. During use, the first motor 11 drives the rotating rod 15 to rotate, which in turn drives the stirring rod 16 to rotate, thereby stirring the raw materials, improving their fluidity, accelerating the contact rate between the raw materials and lipase, and promoting the catalytic reaction rate.

[0034] In a specific embodiment of this example, the second stirring assembly includes a stirring shaft 4 and stirring blades 5 mounted on the stirring shaft 4.

[0035] In this specific embodiment, a second motor 6 is provided on the top of the vessel lid 2, and the output end of the second motor 6 is connected to the stirring shaft 4. During use, the second motor 6 drives the stirring shaft 4 to rotate, which in turn drives the stirring blades 5 to rotate, thereby stirring the lipase. This facilitates the entry of liquid raw materials into the lipase, promoting the reaction between the lipase and the liquid raw materials and accelerating the reaction rate.

[0036] In this specific embodiment, the heating unit includes a heating ring 7, within which a heating wire is disposed. The heating wire is electrically connected to an external power source. The heating wire generates heat, causing the temperature of the heating ring 7 to rise, thereby raising the temperature of the vessel body 1 and increasing the temperature inside the vessel body 1, thus enhancing the lipase activity. A temperature sensor 14 is used to detect the temperature inside the vessel body 1. Based on the temperature detection, the number of heating rings 7 used is selected to control the heating rate. Simultaneously, the heating area can be controlled, selectively heating the upper, middle, or lower part of the vessel body 1 to provide a suitable reaction temperature for the lipase and promote the catalytic process.

[0037] In this specific embodiment, an electric telescopic rod 8 is provided on the vessel lid 2. The drive end of the electric telescopic rod 8 is connected to a movable plate 10. A suction tube 9 is fixed on the movable plate 10, and one end of the suction tube 9 penetrates the vessel lid 2 and extends into the vessel body 1. Lipase can promote the decomposition of oils. When there is too much oil, it will float on the liquid surface. The suction tube 9 can be used to suction out the corresponding oil, facilitating its discharge. The electric telescopic rod 8 can control the height of the suction tube 9 within the vessel body 1, thereby facilitating the suction of oil at different heights and promoting oil recycling and reuse. The suction tube 9 is located between the mesh container 3 and the vessel body 1.

[0038] In operation, the first motor 11 drives the rotating rod 15 to rotate, which in turn drives the stirring rod 16 to rotate, stirring the liquid raw materials inside the vessel 1. The second motor 6 drives the stirring shaft 4 to rotate, which in turn drives the stirring blades 5 to rotate, stirring the lipase inside the mesh tank 3. The fluidity of the liquid raw materials allows for repeated flow within the lipase, promoting contact between the lipase and the liquid raw materials and accelerating the catalytic rate. Simultaneously, an external power source heats the heating wire, which in turn raises the temperature of the heating ring 7, thereby increasing the reaction temperature inside the vessel 1. The temperature sensor 14 monitors the temperature inside the vessel, and heating is stopped when the suitable reaction temperature for the lipase is reached.

[0039] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
