Fuente: WIPO "olive table" The inconveniences of the known machine for the grinding of olives (table A) are as follows: low hourly grinding output, considerable consumption of beaters and grilles, and oxidation of the product. The "multiple grilles" with the beater support shaft B having dual supports 1, 2, enlarges the grinding front and increases the surface of the grilles in several steps. One thus obtains a gradual grinding, with less consumption of the beaters and of the grilles with lower rate of oxidation of the product and a high hourly grinding output. DESCRIPTION: plate A, the currently used machine; plate B, complete beater support shaft; plate C, series of grilles with several steps. Shaft drive motor 1; second shaft support 2; series of beaters 3; series of grilles 4.
