Abstract: Conventional type liquefier appliance that incorporates an anti-drip system consisting of a “T”-shaped spout seal, besides the inclusion of a series of non-slip strips on the connecting gears between the drive unit and the rotary elements, which enable it to come to a sudden stop without the inertia of said elements forcing them in an upward direction, furthermore the grater disc is not fixed to the drive element by a through-screw but rather said screw is welded to its under side, while in addition the push piston terminates in a concavity which engages the piece to be liquefied during use and wherein said piston may be replaced by a feed hole reducer piston.

Abstract: The improvements to the automatic citrus juice squeezer consist of: a movement of the pressure cup (3) by means of a drive screw (5) and a guide column (6); the cup being removably-mounted and detachable from its holder (7) by raising a trip fastener (12) using a catch (13); it has five angularly equidistant blades (2); a squeezer-filter (16) and support assembly (1) can descend against the action of an axial spring (14), maintaining the dynamic connection with the drive shaft by means of gears (18) that may slide along an intermediate sprocket (19); the juice collector (17) empties into a dish (20) which opens/closes a tilting plug (21) as it is introduced/extracted: the blades (2) are connected to the fixed shaft (15) by elastic legs (23) with internal strengtheners (24) which fit into a peripheral neck (25) of the said shaft; and the cup's (3) profile has an enlarged lower curvature to prevent its separation from the squeezer support (1) from narrowing.

Abstract: A machine for extracting juice from citrus fruits, has at least two first cylinders each having a plurality of substantially semi-spherical cavities for accommodating fruits rotatable in opposite directions to transport the fruits, a cutter located downstream of the first cylinders so as to bisect the fruits into two halves which remain lodged in the cavities of the first cylinders, at least two second cylinders located downstream of the first cylinder and each provided with a plurality of substantially spherical protrusions and rotatable so that during rotation the protrusions extend into each fruit embedded in the cavities of the first cylinders with a gap which remains between the protrusions and the cavities and is substantially equivalent to a thickness of a peel of the fruits thereby preventing excessive crushing of the peel. The first cylinders and the second cylinders are rotatable synchronously so that the peel remains sticking to the protrusions. The protrusions are provided with grooves.
