A cassava pulverizer was fabricated and tested for starch extraction from cassava at Masinda Cassava Starch Cooperative Society in Malawi. When tested, the pulverizer increased the starch extraction percentage from cassava by 16.9% as compared to grating only and it showed that these results were significantly different (P<0.05) from the starch extraction from grating only. Given the current starch extraction rate of 18%, a 16.9% increase in the rate when the pulverizer is used represents a three percentage point increase in the extraction rate. Thus, when the pulverizer is used, the starch extraction rate can potentially be as high as 21%. Although, the pulverizer used an extra power of 3.5 horse power, it was economically to incorporate a pulverizer in starch extraction.
