ABSTRACT:
A modulating machine is used to extract and recover the essential oil from citrus fruit such as lemons, oranges, mandarins, grapefruit, etc. not removing their peel, but by microperforating it and disrupting oil cells. The oil thus extracted is trapped in water so as to form an aqueous emulsion. The created machine includes a set of grooved disks (9) mounted over corresponding supporting axes (8); a base structure (1) on which lower portion there is a transmission set installed, formed by pulleys (2) and chains or grooved belts (3) operated by a motor (4); a set of supporting axes (8) provided with alternate axial and rotational movement, by a set of operation members (10) interconnected to rod (11) transmitting alternate movement to the connected handles (12), alternating to the ends (13) of the supporting axes (8). The machine also includes an emulsion tank (15) laterally provided with collectors (16); spillway (30); disk cleaning set (9) fruit washing and drying unit; and an automatic lubrication system for application of oil and grease at specific points.
