Abstract

A method of extracting clear juice from apples and similar fruit involving the use of a screw press having a feed screw with a very gradual continuous slope of the body of the feed screw such that the fruit is gently compressed as it passes through the screw press. The fruit is introduced into the input of a first of such presses and the juices and solids expressed from such gradual compressing are filtered and the juice separated from the remaining solids which are then reintroduced into the input for additional compressing. A second press of the same type may receive the pressed fruit pulp from the output of the first screw press and additional juice extracted therefrom.

Claims

1. A method of extracting clear juice from apples or the like comprising the steps of:

(a) introducing the fruit into the input of a first screw type press having a gradual continuous slope of the body of the feed screw;

(b) gently compressing the fruit in the screw type press to express juice and solids from the fruit;

(c) filtering the expressed juice and solids;

(d) separating and collecting the clear juice from the expressed solids; and

(e) reintroducing the separated expressed solids into the input of the screw type press.

2. The method as defined in claim 1 comprising the further steps of:

(f) collecting the pressed fruit pulp from the output of said screw type press;

(g) introducing the collected compressed pulp into a second screw type press; and

(h) repeating steps (a) through (f) in the second screw type press.

3. The method of claim 2 comprising the further steps of combining the separated and collected clear juices from the first and second screw type presses.
