Microwave Extraction Advantages:
1. Traditional heat extraction is
carried out by the heat conduction and thermal radiation mode. Microwave
assisted extraction simultaneously start both inside and heating. There is no
high temperature heat source, to eliminate the thermal gradient. Therefore the
extraction quality greatly improved, and effectively protect functional
ingredients in food, medicine and other chemical materials.
2. Microwave works by emitting
penetration waves heating method so it significantly saves time consuming.
According to statistics, regular 8 hours job, the same size microwave only
takes dozens of minutes to complete.
3. Microwave has a power extracting
ability, microwave completely extract material one time rather than a couple of
times or three time by regular extracting methods.
4. Microwave extraction Microwave extraction is without thermal inertia, and easily control.
5. Microwave extraction has a higher purity.
6. Lower extracting temperature,
without gelatinization phenomenon, easily separate and further process in order
to save energy.
7. Less Solvent (50%~90% less than normal extraction).
8. Using electricity do not
require boiler and burner so it is an environmentally friendly machine.
9. Small footprint and easily installation. It suits for large, medium, small food, essential oil and medicine corporations.
