A rotary air impact peanut blancher was developed for removing the skins of preconditioned whole raw peanuts. It consists of a revolving cylinder equipped with an abrasive rough interwall surface and a plurality of air jets located interior to the revolving cylinder. The jets are positioned in a manner that causes the air flow to be directed counter to the rotation of the drum. As the drum rotates the nuts in the cylinder move up the side of the cylinder meeting the jets of air. The impact between the nuts and air jets along with the aid of the abrasive surface removes the skin from the peanuts. The system can be used for either batch or continuous blanching.
