Description

Extraction is also called diyestion or lixiviate. It is unit operation used widely for pharmaceutical and chemical production.

Because more effective component exists in the interior of plant cell, so during the period of diyestion, the rate of mass transfer is very slow. In general it takes 5~6 hours or even more longer. Microwave extraction is a mew extracting technology. It strengthens heat and mass transfer on the basis of traditional extraction process.

Applications

This equipment is widely used for flavor, flavoring, natural coloring matter, Chinese herbal medicine, cosmetic, etc.

Main features

Compared with traditional thermal extraction, microwave extraction has the following advantages:

1.       High quality, can protect effective constituent of foodstuff, medicine and other material effectively;

2.       The reaction or extraction is fast and saves about 50%~90% of time;

3.       Solvent to be used is small (compared with routine method, it may reduce 50%~90%);

4.       It has wide selectivity to material to be extracted;

Low energy consumption, without pollution, small investment of equipment, simple operation, safety and reliability.v
