A laboratory huller of the centrifugal impact type is described and test data on sunflower seed and oats are given using percentage of seed hulled and meats broken as criteria of efficiency. It is shown that hulling efficiency is a function of impact velocity and moisture content of the seed. Low moisture levels give almost complete hulling with high meat breakage while higher moisture levels give practically no breakage of meats but lower levels of hulling.By selecting proper conditions of moisture and impact velocity it was possible to obtain 90 to 95% hulling with less than 10% of broken meats. It is suggested that improved efficiency might be obtained by flash drying to render the hulls more brittle without affecting the moisture level in the meats.
