[0038] How it works

[0039] When the device for extracting succinic acid from fermentation liquid is needed, the main material is transported to the lower half of the filter cartridge 1 through the liquid inlet and filtered through the filter part 11 and the ultrafiltration membrane 12;

[0040] Then start the pump 5 to deliver the filtered liquid to the interior of the reaction tube 2, operate the external motor to drive the metering wheel 92 to rotate, so as to achieve uniform addition of NaCl, cooperate with the operation of the rotary motor 23 to drive the stirring rod 21 and the plurality of stirring blades 22 to rotate, further achieve stirring, and accelerate the reaction;

[0041] After the reaction is completed, the liquid is selectively filtered by the first-order salt selective dialyzer 8 during the process of being transported to the collecting cylinder 3. The liquid can be moved to the collecting cylinder 3 and fall into the arc hopper 31 of the collecting cylinder 3. The heating element 32 is started to heat the arc hopper 31, and the fallen liquid is further heated and concentrated. When it falls to the lower half of the collecting cylinder 3, the crystallization device 33 is started to crystallize it, and the processing is completed. The liquid is then discharged to the collecting drawer 4 and taken out.
