Title
(EN) SCREW PRESS FOR COLD PRESSING OF OILSEEDS
(FR) PRESSE À VIS POUR PRESSAGE À FROID DE GRAINES OLÉAGINEUSES
Abstract
(EN)
Screw press for cold pressing of oilseeds used for producing vegetable oils, having a housing (1) with longitudinal spline ways (2) inside. An inlet opening (3) in the front part of the housing and outlet openings (5) for the pressed out oil in its middle part are provided. A screw (6) with a slightly rounded screw header (7) in the housing ends in a screw tip (17) shaped like a truncated cone. The press has a screw head (8) with a central opening (9) and a nozzle (14) with a frustoconical nozzle hole (15) converting into a discharge opening (16), also frustoconical. In the front face (10) of the press head (8) there are triangular splines (11). The generants k1 and k2 of the nozzle hole (15) and the truncated cone of the screw tip (17) form respectively angles a and β with the O-axis, wherein a > β, i.e. the gap between the nozzle hole (15) and the screw tip (17) becomes narrower towards the discharge for the solid residue.
(FR)
La présente invention concerne une presse à vis pour le pressage à froid de graines oléagineuses utilisées pour la production d'huiles végétales, comportant un logement (1) pourvu de cannelures longitudinales (2) en son sein. Une ouverture d'entrée (3) dans la partie avant du logement et des ouvertures de sortie (5) pour l'huile pressée dans sa partie centrale sont prévues. Une vis (6) dotée d'une tête de vis légèrement arrondie (7) dans le logement se termine en une pointe de vis (17) façonnée comme un cône tronqué. La presse présente une tête de vis (8) dotée d'une ouverture centrale (9) et une buse (14) dotée d'un trou de buse tronconique (15) se transformant en une ouverture d'évacuation (16), également tronconique. Des cannelures triangulaires (11) se trouvent dans la face avant (10) de la tête de presse (8). Les cercles générateurs k1 et k2 du trou de buse (15) et du cône tronqué de la pointe de vis (17) forment respectivement des angles a et β avec l'axe O, où a > β, c'est-à-dire l'espace entre le trou de buse (15) et la pointe de vis (17) devient plus étroit vers l'évacuation pour le résidu solide.
