✴Micro encapsulation is used to enclose solids,, liquids, gases.

AIR SUSPENSION TECHNIQUE IN MICROENCAPSULATION :

✴Micro encapsulation by air suspension is a technique that gives improved control and flexibility compared to pan coating.

✴It is a technique of coating the fine solid core materials are substance by a vertical current of air and sprayed with wall material solution..

✴The process can be repeated to achieve film thickness.

✴The size of core particles are usually large..
