Organic Acid Fermentation Extraction Equipment and Solution

Lactic acid and citric acid are widely application in the food,pharmaceutical, especial the demand for Lactic acid has increased considerably because of its use as a monomer in the preparation of PLA,which is a biodegradable and biocompatible polymer that will replace polyethylene and PE plastic, eliminate the pollution of "white plastic" to nature and deal with the problems caused by the reduction of resources such as oil.

Produce organic acids has many methods, but the most promising is biological fermentation.Produced by fermentation, organic acids are generally low in concentration and accompanied by impurities, and the coupling separation process to extract organic acids is an effective means of extraction, separation and concentration.

Organic Acid Purification Process

Solution：Multistage Liquid–Liquid Countercurrent Continuous Extraction

Multistage Liquid–Liquid Process Description:
1. The Multistage Liquid–Liquid Extraction process is not limited to four-stage pickling, alkali washing and water washing, and the number of countercurrent washing stages can be increased according to the actual situation;
2. The Multistage Liquid–Liquid Extraction process is suitable for separating organic mixtures immiscible with water such as acetochlor, alachlor, etc.;
3. The Multistage Liquid–Liquid Extraction process relies on centrifugal separation (hundreds to thousands of times the gravity under the same conditions), and the separation efficiency is high;
4. The Multistage Liquid–Liquid Extraction process equipment occupies a small area, low power consumption, and less residual liquid, which can realize the continuous production of the acetochlor washing process section;

Relative equipment

Mixer Settler

Mixer settlers are a class of Mixing Separation equipment used in the solvent extraction process. A mixer settler reactor consists of a first stage that mixes the phases together followed by a quiescent settling stage that allows the phases to separate by gravity. Mixer Settler is made by overall injection molding, without bonding or weld seams which by Prosea Tech design and manufacture.
