ABSTRACT:
The horizontal press appears as an elongated hollow structure (1) of flat profile resting on a frame (2a, b, c, d), and comprises a ram (6) reciprocated by a fluid power cylinder (5), a hopper (8) through which crushed and stemmed grapes fall into an inlet chamber (9) coinciding with the space swept by the ram, and a compression chamber (112) of tapered longitudinal section terminating in a narrow outlet (13) from which the pressed skins emerge. The top of the compression chamber consists in the flexible undersides (115) of a succession of inflatable cushions (120a . . . n) by which a downward compressive force is applied to the grapes, whilst the bottom takes the form of a continuous belt (122) fashioned from a filtering material, looped flexibly around at least two end rollers (123, 124) and supported by a frame (128) in such a way as to pass above and below a trough (125) from which the filtered juice is drawn off by conventional means.
