ABSTRACT:
An apparatus for extracting juice from citrus fruits comprising a feeding conveyor for conveying the whole fruits to a cutting device, which cuts the fruits into halves. The fruit halves are fed into a squeezing tunnel with their cut surface oriented in a predetermined direction. The squeezing tunnel consist of two opposed surfaces which converge towards one another, thus effecting the squeezing of the fruit halves which are caused to travel therealong. One of the said surfaces is a portion of a rotating drum conveyor, while the other surface comprises a plurality of consecutive parallel rotating rollers arranged transversely with respect to the direction of travel of the fruit halves, and rotating at a peripheral speed which is higher than the speed of the drum conveyor. The rotating rollers are screw threaded with alternating right and left screw threads, or each rotating roller is provided with contiguous right and left screw threaded portions. In this manner, the fruit half, while being squeezed, is subjected to a stretching action, which prevents the rolling up or curling of the fruit half.
