An energy-conserving practical ceramic membrane dialysis unit that adds water's concrete working process:

after the culture of the amino acid fermentation liquor is finished, the amino acid fermentation liquor is inactivated by feed liquid from a fermentation liquor tank and then is conveyed to a fermentation liquor storage tank 1, and a plurality of auxiliary filter aids are added according to different varieties of processes, and the amino acid fermentation liquor is subjected to sterilization filtration after the pH is adjusted.

The amino acid fermentation liquor is continuously filtered out along with permeate liquid in the degerming process, the concentration of impurities such as protein in trapped liquid is continuously improved, the flux of permeate liquid of a ceramic membrane can be rapidly reduced, the membrane-entering pressure and transmembrane pressure difference are gradually improved, when the permeate liquid is concentrated to a certain multiple, dialysis water needs to be added into the trapped concentrate liquid of a storage tank, the dialysis water flow is added by the device, the pressure of the required water is calculated according to the diameter of the storage tank, and then a cleaning ball is arranged in the fermentation liquor storage tank.

The dialyzing water booster pump 5 is provided with a frequency converter to adjust the pressure of dialyzing water, and the dialyzing water is heated by the plate heat exchanger 10 and then is set to have the same value with the temperature of the fermentation liquor in the raw material tank.

The dialysis water is added into the fermentation liquor storage tank for dialysis uniformly, and through multi-batch tests, 10% less dialysis water and more than 20% dialysis water are added into the fermentation liquor with the same volume, so that the acid content of the concentrated solution intercepted on the surface is below 5 g.
