Abstract
Abstract An arrangement for continuously separating fruits has a housing, a sieve element rotating in the housing and a hammer element rotating inside the sieve element, wherein the sieve element rotates with the speed which is lower than the speed of rotation of the hammer element and the relation between the speeds of rotation of the hammer element and the sieve element is within the region of between 2:1 and 4:1. A method of continuously separating fruits include withdrawing the extracted fruit juice from the inventive arrangement and supplying the same into a screw centrifuge so as to clarify the fruit juice in the latter and to produce a white wine. Red pigment of the fruit skin can be introduced into the fruit juice so as to produce a red fruit wine.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
224 words
An arrangement for continuously separating a fruit pulp from a fruit skin and a fruit core of a fruit having a predetermined diameter, comprising a housing; a conical sieve element rotating in said housing; a hammer element rotating inside said sieve element so that the latter surrounds the former and including a plurality of conical hammer units detachably arranged and spaced from one another in an axial direction; means for rotating said hammer element with a predetermined speed of rotation and including a hollow shaft carrying said hammer units of said hammer element so as to form an axis of rotation of the latter and a driven shaft having a pin engaging in said hollow shaft; means for rotating said sieve element with a speed of rotation which is lower than the speed of rotation of said hammer element, so that the relation between the speed of rotation of said hammer element and the speed of rotation of said sieve element is within the region of between 2:1 and 4:1; means for adjusting said hammer units and arranged between said hollow shaft and said pin of said driven shaft; and a regulating disc located inside said sieve element above said hammer element and spaced from an inner surface of said sieve element by a distance which is greater than the diameter of the fruit.
Claim 2
Dependent Claim
224 words
An arrangement for continuously separating a fruit pulp from a fruit skin and a fruit core of a fruit having a predetermined diameter, comprising a housing; a conical sieve element rotating in said housing; a hammer element rotating inside said sieve element so that the latter surrounds the former and including a plurality of conical hammer units detachably arranged and spaced from one another in an axial direction; means for rotating said hammer element with a predetermined speed of rotation and including a hollow shaft carrying said hammer units of said hammer element so as to form an axis of rotation of the latter and a driven shaft having a pin engaging in said hollow shaft; means for rotating said sieve element with a speed of rotation which is lower than the speed of rotation of said hammer element, so that the relation between the speed of rotation of said hammer element and the speed of rotation of said sieve element is within the region of between 2:1 and 4:1; means for adjusting said hammer units and arranged between said hollow shaft and said pin of said driven shaft; and a regulating disc located inside said sieve element above said hammer element and spaced from an inner surface of said sieve element by a distance which is greater than the diameter of the fruit.
Claim 3
Dependent Claim
83 words
An arrangement as defined in claim 1; and further comprising means for sensing the speed of rotation of said sieve element and the speed of rotation of said hammer element, and control means operative for stopping said sieve element and said hammer element when the speed of rotation of said sieve element exceeds a predetermined value, said control means being connected with said sensing means and operating so that said control means first stops said hammer element and thereafter stops said sieve element.
Claim 4
Dependent Claim
25 words
An arrangement as defined in claim 1, wherein said means are arranged so that said sieve element and said hammer element rotate in opposite directions.
Claim 5
Dependent Claim
25 words
An arrangement as defined in claim 1, wherein said sieve element is conical and has a cone angle equal to substantially between 10° and 15°.
Claim 6
Dependent Claim
57 words
An arrangement as defined in claim 1, wherein a fruit core to be separated has a predetermined diameter, said sieve element having a plurality of slots with a width which is smaller than the diameter of the fruit core, and a length which is equal to at least three times of the diameter of the fruit core.
Claim 7
Dependent Claim
19 words
An arrangement as defined in claim 5, wherein said slots of said sieve element extend in a horizontal direction.
Claim 8
Dependent Claim
19 words
An arrangement as defined in claim 5, wherein said slots of said sieve element extend in a vertical direction.
Claim 9
Dependent Claim
26 words
An arrangement as defined in claim 5, wherein said slots of said sieve element has a flow cross section which conically increases in an outward direction.
Claim 10
Dependent Claim
39 words
An arrangement as defined in claim 1, wherein a fruit core to be separated has a predetermined diameter, said sieve element having a plurality of openings with a diameter which is smaller than the diameter of the fruit core.
Claim 11
Dependent Claim
56 words
An arrangement as defined in claim 1, wherein said shafts are spaced from one another in an axial direction, each of said hammer units having a hub mounted on said hollow shaft and at least two elongated diametrically opposite hammer members each extending from the respective hub and having an identical height over its entire length.
Claim 12
Dependent Claim
25 words
An arrangement as defined in claim 10, wherein each of said hammer units has more than two such hammer members extending from the same hub.
Claim 13
Dependent Claim
49 words
An arrangement as defined in claim 1, wherein said hollow shaft has an inner thread, said adjusting means including a sleeve provided with an outer thread engageable with said inner thread of said hollow shaft, said sleeve having an end portion abutting against and connected with said driven shaft.
Claim 14
Dependent Claim
29 words
An arrangement as defined in claim 12; and further comprising means for connecting said end portion of said sleeve with said driven shaft, said connecting means including a screw.
Claim 15
Dependent Claim
31 words
An arrangement as defined in claim 1, wherein said means for rotating said hammer element includes a hollow shaft carrying the latter, said regulating disc being mounted on said hollow shaft.
Claim 16
Dependent Claim
26 words
An arrangement as defined in claim 14; and further comprising means for mounting said regulating disc on said hollow shaft and including an intermediate threaded member.
Claim 17
Dependent Claim
22 words
An arrangement as defined in claim 15; and further comprising an inlet cone connected with said threaded member of said mounting means.
Claim 18
Dependent Claim
54 words
An arrangement as defined in claim 1; and further comprising a frame including a stepped support element, said means for rotating said sieve element including a first drive motor, said means for rotating said hammer element including a second drive motor, said drive motors being mounted on said stepped supporting element of said frame.
