Lactic acid purification introduction:

Liquid–liquid extraction is the most widely used method for the extraction of analytes from aqueous food samples. In LLE, the sample is distributed or partitioned between two immiscible solvents in which the analyte has different solubilities. The solution containing the analyte must be immiscible with the solvent used to extract the analyte. The main advantages of this method are the wide availability of solvents and the use of low-cost apparatus. However, low recoveries, limited selectivity, and time-consuming procedures limit LLE. A variety of microscale variants of LLE have been reported and food applications of these have been recently review.

Lactic acid purification Unit:

Lactic acid purification Unit,Centrifugal extractor is a new type, fast and highly efficient liquid-liquid extraction separation equipment, it is different with traditional extraction equipment such as mixer settler, extraction tower . Centrifugal extractor using the motor driven drum to reach high speed, the densities of different and not mutually mixed solution of two liquids in drum or blade rotation shear stress under complete mixing and mass transfer, and in high-speed rotation drum of centrifugal force under the action of rapid separation.

Lactic acid purification Unit work principle:

1. Mixed and mass transfer process

Our CWL-M series of Lactic acid purification Unit is our independent R&D equipment with patents, it is different with other traditional extraction equipments, with many advantages, For example:

1. Simple and stable structure
Top-suspension structure, no bearing and mechanical seal at the bottom, no leakage risk, easy to maintain and save maintenance cost, long service life;
2. Energy-saving
Large capacity, more energy-saving (under the same capacity condition, the power consumption is 1/10-1/3 of the annular type);
3. Corrosion resistance
Equipment could adopt perfluoro polymer material, resistant to strong acid (hydrochloric acid, mixed acid etc.);
4. Good effect of mixing and separation
Various hybrid structures could be chosen, good separation effect, adapt to easily emulsified system;
5. Easy to change heavy phase weir
When changed liquid system, heavy phase weir could be replaced quickly, simple and easy operation;
6. Low liquid residual
Equipment with small valid volume;
7. High automation
It could realize timely monitoring on line, optional on-line cleaning system for GMP standard, and adapt to both intermittent and continuous running completely.

1.Pharmaceutical Industry (Raw material of medicine, medical intermediate)
For example:
Raw material of medicine, reaction liquid of medical intermediate or solvent continuous extraction and washing; Organic phase and aqueous phase continuous separation; Natural medicine extraction(Such as artemisinin, caulis sinomenii, bilobalide and so on);
Antibiotics (Such as penicillin, lincomycin, gibberellin and so on);
Vitamin extraction (Such as pantolactone and so on).
2.Fine Chemicals/Petrochemical Industry
For example:
Chemical intermediate, raw liquid of pesticide and other reaction liquid and solvent continuous extraction and washing and so on,
Organic phase and aqueous phase continuous separation;
Lube oil purification and extraction, Diesel oil purification and extraction.
3.Food Fermentation Industry
For example:
Lactic acid fermentation broth extraction, Citric acid fermentation broth extraction, Natural plant pigment extraction (Such as chlorophyll) and so on.
4. Hydrometallurgy Industry
Chemical metal element extraction and separation (Such as Nickel, Cobalt, Copper, Zinc, Rubidium, Cesium, Manganese and so on);
Rare earth element separation and extraction;
Lithium and Boron extraction from Brine
5.Wastewater Treatment
For example:
Phenolic wastewater treatment, Printing and dying wastewater treatment(Such as H acid, K acid and so on), DMF wastewater treatment, Hight concentration chemical organic wastewater treatment, Naphthalene sulfonic acid wastewater treatment and so on.
6. Oil And Water Separation ( Both Include remove oil from water and remove water from oil).
