[0002] Enzymes are organic compounds with catalytic properties produced by living cells. Most are proteins, with a small fraction being RNA. The study of their basic properties is called "enzymology." The application of enzymes is called "enzyme engineering." The industrialization of enzymes has led to the development of the enzyme preparation industry, which has permeated various industrial sectors. Enzymes have gained widespread application due to their unique biological functions and high catalytic efficiency. Currently, enzymes are finding increasing application in industries such as medicine, textiles, petroleum, food, and papermaking.

[0003] In the separation and purification of biological enzymes, temperature and pH are two very important factors because they can affect the activity and stability of the enzymes. For example, Chinese application number 202120506704.1 discloses a β-xylosidase separation device that is easy to clean. However, the device cannot heat or cool the biological enzyme, making it impossible to maintain temperature stability during the separation and purification process, thereby causing enzyme inactivation or degradation. Utility Model Content

A second outer tank is arranged outside the first outer tank. The inner wall of the second outer tank and the outer wall of the first outer tank form a heating chamber. An electric heater is installed inside the heating chamber.

[0007] In a specific embodiment, the outer side wall of the first outer tank is provided with a plurality of grooves at equal intervals, and the wall of each groove does not contact the outer wall of the membrane separator.

[0008] In a specific embodiment, a plurality of heat conducting plates are provided on the side wall of each groove in an annular array, and each of the heat conducting plates is in contact with the outer wall of the membrane separator.

[0009] In a specific embodiment, the electric heater extends into the interior of each of the grooves.

[0010] In a specific embodiment, a temperature sensor is installed on the top of the membrane separator, and a detection end of the temperature sensor is located inside the membrane separator.

[0011] In a specific embodiment, a flow meter is installed on the cold injection pipe.

[0013] In a specific embodiment, a bracket is installed inside the second outer tank, and the electric heater is installed on the bracket and extends into the interior of each of the grooves.

[0014] Beneficial effect: The cooling chamber and the heating chamber formed by the first outer tank and the second outer tank can not only cool down the membrane separator but also heat it up, so that it can be adjusted according to the actual temperature requirements during biological enzyme membrane separation, preventing the biological enzyme from being inactivated or degraded during membrane separation.

[0022] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0023] See also Figure 1-Figure 5 The present application provides a membrane separation system for active biological enzymes, including a membrane separator 10 and a heating and cooling component 20.

[0024] See also Figure 1 、 Figure 2 and Figure 5 The membrane separator 10 utilizes natural or artificially synthesized polymer membranes to separate, grade, purify and enrich two-component or multi-component solutes and solvents with the driving force of external energy or chemical potential difference, thereby achieving membrane separation of active biological enzymes.

[0025] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 The heating and cooling assembly 20 includes a first outer tank 210, which is disposed outside the membrane separator 10. The inner wall of the first outer tank 210 and the outer wall of the membrane separator 10 form a cooling chamber. The bottom of the first outer tank 210 is connected to a cold injection pipe 260. Specifically, liquid nitrogen or other cold substances that can reduce the temperature can be injected through the cold injection pipe 260. A second outer tank 240 is disposed outside the first outer tank 210. The inner wall of the second outer tank 240 and the outer wall of the first outer tank 210 form a heating chamber. An electric heater 250 is installed inside the heating chamber. Specifically, the electric heater 250 can be an electric heating wire or an electric heating tube. When the active biological enzyme needs to be cooled during membrane separation in the membrane separator 10, a cold substance is injected through the cold injection pipe 260 to reduce the temperature inside the cooling chamber. When the temperature inside the cooling chamber decreases, the temperature inside the membrane separator 10 also decreases. When the temperature needs to be increased, the injection of the cold substance is stopped, and then the electric heater 250 is started to increase the temperature inside the heating chamber, thereby increasing the temperature inside the membrane separator 10. The cooling chamber and the heating chamber formed by the first outer tank 210 and the second outer tank 240 can not only cool the membrane separator 10 but also increase the temperature, so that the temperature can be adjusted according to the actual temperature requirements during the biological enzyme membrane separation, preventing the biological enzyme from being inactivated or degraded during the membrane separation.

[0026] In this embodiment, the outer wall of the first outer tank 210 is provided with a plurality of grooves 220 at equal intervals, and the walls of each groove 220 do not contact the outer wall of the membrane separator 10. The provision of each groove 220 brings the heating chamber closer to the membrane separator 10, thereby improving the heating effect. Furthermore, the absence of contact between the walls of each groove 220 and the outer wall of the membrane separator 10 ensures flow in the cooling chamber.

[0027] In this embodiment, a plurality of heat conducting plates 230 are provided in a circular array on the sidewall of each groove 220, and each heat conducting plate 230 is in contact with the outer wall of the membrane separator 10. The heat conducting plates 230 can quickly transfer heat from the heating chamber to the membrane separator 10, further improving the heating effect.

[0028] In a specific configuration, the electric heater 250 extends to the inside of each groove 220 . A bracket is installed inside the second outer tank 240 , and the electric heater 250 is installed on the bracket and extends to the inside of each groove 220 .

[0029] A temperature sensor 270 is installed on the top of the membrane separator 10, and the detection end of the temperature sensor 270 is located inside the membrane separator 10. The temperature sensor 270 can monitor the temperature inside the membrane separator 10 in real time, so that the required temperature can be known at any time.

[0030] A flow meter is installed on the cold injection pipe 260. Among them, the injected cold material can be calculated.

[0031] The membrane separator 10 is equipped with a membrane separation device.

[0032] The working principle of the membrane separation system for active biological enzymes:

[0033] When the active biological enzyme needs to be cooled during membrane separation in the membrane separator 10, a cold substance is injected through the cold injection pipe 260 to reduce the temperature inside the cooling chamber. When the temperature inside the cooling chamber decreases, the temperature inside the membrane separator 10 also decreases. When the temperature needs to be increased, the injection of the cold substance is stopped, and then the electric heater 250 is started to increase the temperature inside the heating chamber, thereby increasing the temperature inside the membrane separator 10. The cooling chamber and the heating chamber formed by the first outer tank 210 and the second outer tank 240 can not only cool the membrane separator 10 but also increase the temperature, so that the temperature can be adjusted according to the actual temperature requirements during the biological enzyme membrane separation, preventing the biological enzyme from being inactivated or degraded during the membrane separation.

[0034] It should be noted that the specific models and specifications of the electric heater 250, temperature sensor 270 and flow meter need to be selected and determined based on the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0035] The power supply and principles of the electric heater 250 , the temperature sensor 270 and the flow meter are clear to those skilled in the art and will not be described in detail here.

[0036] The foregoing is merely an embodiment of the present application and is not intended to limit the scope of protection of the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included within the scope of protection of the present application. It should be noted that similar reference numerals and letters represent similar items in the following figures. Therefore, once an item is defined in one figure, it does not need to be further defined or explained in subsequent figures.
