The operating mode and performance of various olive milling and pitting machines are presented. In particular: (i) single and double-grid hammer mills; (ii) disc mill; (iii) stone mill; (iv) total and partial pitter mills. Pressure (with impact, shock and percussion mechanisms) and shearing action reduce the olive pulp to a very fine size in order to obtain the most complete release of the oil from the vacuoles. At the same time, the pits are reduced to relatively coarse fragments, guaranteeing an effective draining network. The effects of milling on oil quality are discussed.
