Even with minimal equipment, small-scale yam flour production is possible. Here’s a simplified step-by-step process:
-
Peeling & Washing
Use knives or simple peelers to remove the yam skin. Wash thoroughly to remove dirt and sap. -
Slicing
Slice into thin chips (5–10 mm) for even drying. A food-grade slicer speeds this up. -
Drying
Sun-dry on raised racks or use solar/industrial dryers. Proper drying takes 2–3 days under good sun, or 6–8 hours in a machine. -
Milling
Dried chips are ground into fine powder using a hammer mill or commercial grinder. -
Sieving & Packaging
Sieve for uniform texture, then package in airtight, moisture-proof bags — preferably branded.
