Filter system, nanofiltration system, the microfiltration systems, ultrafiltration system, the sludge outlet of nanofiltration system are equipped with circulated filter system, institute
Circulated filter system is stated provided with regulating valve, circulating tank and drawing liquid pump, the circulating tank is connected with Rinsing Area, the nanofiltration system
Outlet be sequentially connected equipment of crystallisation by cooling, the first centrifugal device, wash brilliant device, the second centrifugal device and drying unit；
Further, acticarbon built in the filter.
Further, the drying unit is drying device by microwaves.
Further, high-pressure pump, pressure gauge, temperature are respectively equipped with the microfiltration systems, ultrafiltration system and nanofiltration system
Meter, flowmeter.
The technology of the present invention beneficial effect：
A kind of novel lactic extraction system of the present invention, it is simple in construction, easy to use, can long-term safety extraction lactic acid, convenient breast
The circulating filtration purification of acid, it is ensured that product quality, is improved under the recovery rate of lactic acid, whole UF membrane, concentration process normal temperature
Carry out, saved the energy.
