What You Need to Know
Forced convection accelerates water migration from food matrices through vapor pressure differentials, with Maillard reactions occurring above 60°C.
Produces shelf-stable ingredients with concentrated flavors while preserving some heat-sensitive nutrients better than sun drying.
