A method and system of processing citrus fruit is shown. A peeling chamber has opposing ends and a fruit inlet and fruit outlet formed at respective opposing ends. Abrasive rollers are rotatably mounted in an arcuate configuration within the peeling chamber at an area forming a lower portion of the peeling chamber. Citrus fruit is fed into the peeling chamber through the fruit inlet to the fruit outlet. The citrus fruit engages the rotating abrasive rollers with a residence time within the peeling chamber for peeling off the outer surface of the fruit in an amount sufficient to remove a majority of the oil within the citrus fruit and leaving sufficient peel thickness for maintaining peel integrity.
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.
