[0031] like Figure 1 As shown, an embodiment of the present application provides a recycling and processing system 100, which is mainly used to recycle products of enzyme-catalyzed synthesis processes.

[0032] The recovery and processing system 100 includes a reaction device 110 , a solid-liquid separation device 120 , a filtration device 130 , a recrystallization device 140 and a collection device 150 .

[0033] The reaction device 110 is used to produce the reacted material, which includes the product of the enzyme-catalyzed synthesis of the original material, the excess original material and the catalytic enzyme.

[0034] The solid-liquid separator 120 is connected to the discharge end of the reaction device 110 and is used to separate large solid particles from the material. The filter 130 is connected to the discharge end of the solid-liquid separator 120 and is used to separate small solid particles from the material. The collector 150 is connected to the discharge end of the recrystallization device 140 and is used to collect the filtered material. By providing the solid-liquid separator 120 to separate large particles of inactive catalytic enzyme from the material, and then using the filter 130 to remove fine impurities from the material, the liquid material collected by the collector 150 is low in impurities.

[0035] In some embodiments, the recycling system 100 further includes a recrystallization device 140 .

[0036] The recrystallization device 140 is connected to the discharge end of the filtering device 130. The recrystallization device 140 is used to concentrate the filtered material, so that the volume of the product can be reduced and it is convenient for storage.

[0037] In some embodiments, the recrystallization device 140 includes a concentration module 141 and a condensation module 142 . The feed end of the concentration module 141 is connected to the discharge end of the second filtration module 132 , and the cold air output end of the condensation module 142 is connected to the concentration module 141 .

[0038] For example, the concentration module 141 is a concentration kettle. It is understood that the working principle of the concentration kettle is mainly to increase the solute concentration in the solution by evaporating the solvent in the solution.

[0039] The concentrator in this application does not have a heating device and utilizes a stirring device to promote solvent volatilization, which helps reduce energy consumption and facilitates the collection of low-boiling-point enzyme-catalyzed products. The concentrator removes some or all of the solvent from the product of the enzyme-catalyzed synthesis reaction at low temperatures, thereby increasing the concentration of the solution.

[0040] In some embodiments, the concentration module 141 has a solvent discharge end 1411 and a material discharge end 1412 .

[0041] Condensation module 142 is used to coordinate the amount of solvent in the concentration vessel. The cold air generated by condensation module 142 condenses the solvent. When the solvent concentration in concentration module 141 is high, excess solvent is discharged from solvent outlet 1411 of concentration module 141. When the solvent concentration in concentration module 141 is low, the condensed solvent flows back into concentration module 141 from solvent outlet 1411.

[0042] In some embodiments, the collection device 150 includes a collection container 151 and a vacuum pump 152 .

[0043] The collecting container 151 is connected to the material discharge end 1412 of the concentration module 141 , and the vacuum pump 152 is connected to the collecting container 151 . By turning on the vacuum pump 152 , the material is accelerated to flow from the material discharge end 1412 of the concentration module 141 to the collecting container 151 , thereby improving efficiency.

[0044] In some embodiments, the filter device 130 includes a first filter module 131 .

[0045] The first filter module 131 includes a circulation container 1311 and a cleaning container 1312 . The feed end of the circulation container 1311 is connected to the discharge end of the solid-liquid separation device 120 , and the discharge end of the cleaning container 1312 is connected to the discharge end of the circulation container 1311 .

[0046] The circulation container 1311 is typically used in processes that require continuous circulation of liquids, such as chemical, pharmaceutical, and food processing industries. Its main function is to keep the liquid in a flowing state for operations such as mixing, reaction, or cooling.

[0047] The cleaning container 1312 is mainly used to remove residues, contaminants or biofilms to ensure the cleanliness and sanitary conditions of the equipment.

[0048] In some embodiments, the cleaning container 1312 is provided with a clean water feed end, the discharge end of the cleaning container 1312 is provided with a first sewage outlet 13121, and the discharge end of the circulation container 1311 is provided with a second sewage outlet 13111. The first filtration module 131 adds pure water to the filtrate produced by the solid-liquid separation device 120 to mix and dilute the filtrate while coarsely filtering the solid particles in the filtrate.

[0049] The solid particle impurities generated by the rough filtration are discharged from the first sewage outlet 13121 or the second sewage outlet 13111, thereby reducing the filtration pressure of the second filter module 132, extending the service life of the second filter module 132, and reducing costs.

[0050] In some embodiments, the cleaning container 1312 is further provided with a condensation line 13122 . The condensation line 13122 is disposed in the cleaning container 1312 to reduce the temperature of the liquid in the cleaning container 1312 .

[0051] In some embodiments, the filtering device 130 further includes a second filtering module 132 .

[0052] The feed end of the second filter module 132 is connected to the discharge end of the cleaning container 1312, and the discharge end of the cleaning container 1312 is connected to the recrystallization device 140, which finely filters the filtrate produced by the first filter module 131, thereby reducing or even removing solid impurities in the product.

[0053] In some embodiments, the second filter module 132 includes at least three filter membrane assemblies, which are connected in sequence, and the discharge end of each filter membrane assembly is connected to the feed end of the cleaning container 1312 respectively.

[0054] like Figure 1 As shown, a control valve assembly 133 is further provided between the cleaning container 1312 and the second filter module 132 to control the total amount of liquid filtered by the second filter module 132 each time, so that the filtrate passing through the first filter module 131 can pass through the second filter module 132 in sequence, thereby improving the filtering effect of the second filter module 132.

[0055] The discharge end of each filter membrane assembly is connected to the feed end of the cleaning container 1312, so that the concentrated water outlet of each filter module assembly is connected to the cleaning container 1312, thereby achieving a circulating filtration effect.

[0056] like Figure 1 As shown, there are three filter membrane assemblies, which are divided into three stages to filter the liquid. It should be understood that the number of filter membrane assemblies can be set according to actual needs.

[0057] In some embodiments, the filtration membrane component is any one of a reverse osmosis membrane, a microfiltration membrane, an ultrafiltration membrane, and a nanofiltration membrane.

[0058] In some embodiments, the solid-liquid separation device 120 is a plate and frame filter press.

[0059] It can be understood that the working principle of the plate and frame filter press is: first, the suspension is pumped into the closed plate and frame; the liquid flows out through the filter cloth to become filtrate, and the filtrate flows to the filter device for filtration, while the solids are retained on the filter cloth to form a filter cake; when the filter cake fills the entire filter chamber, the feeding is stopped, the clamping device is loosened, the filter plate is removed, and the filter cake is removed.

[0060] The workflow of the recycling and processing device of this application is as follows:

[0061] The material after the reaction in the reaction device 110 first passes through the solid-liquid separation device 120 for solid-liquid separation, and the separated liquid enters the circulation container 1311;

[0062] The liquid flowing out of the circulation container 1311 is mixed with the pure water flowing out of the cleaning container 1312 to clean the liquid;

[0063] The mixed liquid passes through the second filter module 132 to filter out impurities and then enters the concentration module 141;

[0064] The concentration module 141 cooperates with the condensation module 142 and the vacuum pump 152 to separate and concentrate the liquid product to be recovered, and finally condenses the recovered material into the collection container 151 .

[0065] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification and features of different embodiments or examples without contradiction.

[0066] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present application.
