Machine for extracting juice from citrus fruit, particularly oranges
| Details |
Inventors: Antonio, Cimenti;
Assignee:
Primary Examiner: Simone; Timothy F.
Assistant Examiner:
Attorney, Agent or Firm: Wenderoth, Lind & Ponack
A machine for extracting juice from citrus fruit, in particular oranges, includes an inclined chute conveying the fruits to be squeezed against a step, a spoon that raises the fruit resting on the step, and two squeezing plates below the step. The plates include a front plate and a back plate, the front plate being pivoted at its upper part and urged by a spring toward the back plate. The back plate is connected to a connecting rod and crank driven by a speed reducer by which the back plate is slid longitudinally horizontally toward and away from the front plate. As the two plates converge, the fruit interposed therebetween is squeezed by the back plate. Juice thus extracted from the fruit drips into an underlying hopper and from there is collected in a container. Afterwards, as the back plate moves away from the front plate, the residue of the previously squeezed fuit falls down on an inclined grill disposed over the hopper and is collected in a collecting drawer. |

DETAILED DESCRIPTION The object of the present invention is to obviate the above-indicated drawbacks and restrictions of the prior art.
This object is achieved by the machine of the present invention, which machine is compact and comprises: feeding and squeezing members for feeding and squeezing the fruit, means for driving said feeding and squeezing members, adapted to actuate them cyclically in a coordinated way, and collecting means for collecting the residue of the fruit after being squeezed, which members and means are all very simple and reliable and which machine permits fruits of considerably different sizes to be squeezed in very rapid cycles and, finally, to facilitate the complete cleaning of the members coming in contact with the fruit and with the juice therefrom.
Such machine comprises a conveyor provided with a feeding element for feeding a piece of fruit at the beginning of each cycle of the machine to a squeezing unit, the squeezing unit for stopping, positioning and squeezing the fruit as well as for discharging the residue thereof, suitable conveyor for forwarding the residue toward a suitable collecting element, collecting and conveying means for conveying and collecting the juice produced during the squeezing of the fruit.
The machine is characterized in that said conveyor is constituted by an adequately inclined chute at the lower end of which a stop element is situated, which is constituted by a step; said feeding element is arranged near said lower end and is constituted by a spoon adapted to lift the fruit disposed thereon over said step; the squeezing unit includes a front plate pivoted at its upper side and biased by suitable resilient means toward an inclined position, a horizontally slidable back plate guided by adequate guiding means for movement toward and away from said front plate by an associated driving unit.
The driving unit also operates said spoon at the beginning of each cycle.
The front and about plates initially converge toward each other such that a piece of fruit admitted therebetween stops while being positioned therebetween
