Fecha de publicación: 01/04/2022 Fuente: Wipo "olive oil" The utility model provides a cold pressing device for olive oil production, and relates to the technical field of cold pressing devices for olive oil production. The olive oil production device comprises a base, a cold pressing mechanism and an anti-blocking mechanism. The cold pressing mechanism comprises an oil pressing barrel, a first pressing disc, a cold pressing barrel and a second pressing disc. The oil pressing barrel is installed on the base, a supporting rod is installed at the bottom of the oil pressing barrel, the first pressing disc is installed at the upper end of the supporting rod, an oil outlet is formed in the side face of the cold pressing barrel, the side face of the first pressing disc can abut against the inner side of the cold pressing barrel, and the second pressing disc is fixed in the cold pressing barrel. The anti-blocking mechanism comprises a fixing ring fixed to the inner side of the oil pressing barrel, a plurality of dredging strips used for dredging the oil outlet are installed on the inner side of the fixing ring, and one end of each dredging strip extends into the oil outlet. The dredging strip moves relative to the oil outlet to sweep off residues possibly remaining at the oil outlet, so that the situation that the oil outlet is blocked by the residues in the next cold pressing oil outlet process is avoided, and the purpose of ensuring the oil yield is achieved.
