Laboratory RDC - 60 type extraction tower successfully replace the separatory funnel
the type extraction tower as part of the rotary table extraction tower. Severe used way is to use two kinds of solution are different, or additional energy, such as stirring, pulse, vibration, etc. Will break into a liquid droplet, dispersed in a continuous liquid, in order to improve the efficiency of mass transfer, continuous extraction process using extraction tower equipment for many times, namely extraction tower. The extraction process of extraction tower is used in the two phase miscibility of various components in the liquid phase ( Including the objective product) Different solubility. So as to achieve the purpose of separation. It is a common unit operation, the separation of liquid mixtures in fermentation and the application of biological engineering is quite widespread, it not only can extract and a strong product, also can get rid of some other similar material, make the product get preliminary purification.
extraction tower work principle and structure:
extraction tower consists of three parts: the clarification section, the mixed section, under the clarification section. Which mixed section is a cylinder shape, internal by static ring baffles are divided into a series of extraction chamber, between two static ring baffle is fixed wheel, and together with the stirring shaft rotation. At work, the heavy phase ( Water phase) And the light phase ( Organic phase) From the top and bottom to enter respectively, in the tower countercurrent contact. Under the fixed wheel agitation, the dispersed phase formation of small droplets, increase the mass transfer area, after completing the process of extraction, light and heavy phase respectively from the top and bottom out.
RDC- 60 type meaning of extraction tower
RDC - 60 type extraction tower can completely replace the laboratory experiment of the separatory funnel in extraction and separation, the extraction efficiency is significantly higher than traditional extraction equipment. RDC - 60 type extraction tower is a continuous extraction device, extraction, separation, time is short, almost instantaneous, high extraction efficiency, save time and effort save money. Can obtain reliable technological parameters, is essential extraction purification equipment of the laboratory research and development department.
RDC- Summary of 60 type extraction Tate.
1. Beautiful appearance, simple structure, easy to operate and large elasticity of operation, large flux;
2。 Processing capacity big, suitable for continuous production;
3。 Level of high efficiency, small amount of solvent retention;
4。 Mass transfer speed, not easy emulsification;
5。 Cover an area of an area small, low maintenance cost;
6。 High extraction efficiency - — Phase equilibrium set up fast, easy to implement series single stage or multistage counter-current or wrong washing and extraction, high mass transfer efficiency and grade efficiency approaching 100%, stop not to undermine the established after concentration distribution at different levels, can at any time at all levels of sampling, facilitate testing.
7。 Small footprint - — Motor direct drive, no transmission attachments, compact structure, save area and operating space, less auxiliary equipment.
8。 Adaptable -- — Not because of the change of the material influence extraction effect, can deal with small difference in density between the viscosity of the system, and has a strong ability of demulsification.
