Definitions
- the invention relates to a fruit press with a centrally arranged, protruding and upwardly tapering element for pressing out a fruit and an annular surface surrounding the element at the bottom thereof, the element carrying ridges on its outer surface extending from the bottom of the element, between which trough-shaped Wells are arranged.
- Such fruit presses are generally known. They are used to squeeze lemons, oranges, grapefruits and the like. With fruit presses, regardless of whether they are hand-operated or motorized presses, the problem arises of squeezing the fruit juice out of the fruit as completely as possible.
- a fruit press driven by an electric motor is known from EP 0 362 058 B1. In the case of this fruit press, spiral-shaped ribs are present on an outer lateral surface, which rise as narrow strips over an otherwise rotationally symmetrical outer lateral surface.
- this object is achieved in a fruit press of the type mentioned in the introduction in that the ridges and the depressions are arranged in a helical shape.
- burrs are provided according to the invention, there are edges which are sufficiently sharp to tear open the walls between the fruit cells containing the fruit so that the fruit juice emerges.
- the trough-shaped depressions between the ridges provide enough space to ensure that the fruit juice runs off smoothly. Due to the helical arrangement of the ridges, a helical effect is achieved, as a result of which the element rotates into the fruit during the pressing process. This supports the pressing process.
- the operator of the fruit press can press the fruit against the element with less pressure. Due to the helical arrangement of the ridges, the pulp is pressed out without tearing. This increases the juice yield when pressing the fruit, while at the same time reducing the labor force.
- a particularly advantageous development consists in the element being essentially conical and in that the ridges converge to form a central upper tip on the element.
- This shape of the element recreates the shape of the inner wall of the skin of the fruit, in particular a lemon.
- the ridges scratch the inner wall of the fruit so that all the juice is squeezed out of it.
- the fruit press is advantageously designed such that the element is essentially hollow on the inside and has a hollow shaft for plugging onto a shaft journal of a drive shaft. This shape is suitable if the fruit press is driven by a motor.
- the hollow shaft enables a quick connection to the drive shaft of the motor.
- the element, together with the ring surface surrounding it, can easily be pulled off the drive shaft in order to clean it.
- walls are arranged between the hollow shaft and a jacket wall that has the jacket surface on its outside. This measure increases the stability of the fruit press. The item won't deformed when a fruit is pressed against the element with high force to squeeze the juice.
- the hollow shaft is provided with an angular cross section, for example a hexagonal cross section, and thus has a hexagonal wall.
- FIG. 1 shows a fruit press in a cross section in a plane in the region of its bottom
- FIG. 2 shows the fruit press according to FIG. 1 in a perspective view.
- a fruit press 1 has a centrally arranged element 2 which essentially has the shape of a paraboloid of revolution, a hemisphere or a cone and which is surrounded by an annular surface 3 on its base. Fruit juice that arises when a fruit is pressed out over the element 2 collects in the annular surface 3. The fruit juice drips through rib-shaped slots 4 into a container (not shown here) in which it is collected.
- the element 2 is essentially designed as a hollow body, in which a hollow shaft 5 is arranged centrally and projects up to a tip 6 of the element.
- Hollow shaft 5 preferably has the cross section of an n-corner, for example one Hexagons to positively receive a shaft journal of a drive shaft and a correspondingly edge-shaped wall 7.
- Walls 8 adjoin wall 7 at right angles.
- the walls 8 serve as reinforcing ribs and adjoin a jacket wall 8 of the element 2.
- the outer wall 8 On its outer wall, i. H. on its outer surface, the outer wall 8 carries helically arranged ridges 9, each from the bottom of the element 2, d. H. extend from the level of the ring surface 3 to the tip 6. Between the ridges 9 there are troughs 10 through which the fruit juice flows to the ring surface 3.
- the ridges 9 are arranged helically on the element 2 ensures that the element 2 rotates particularly easily into the fruit, in particular if the fruit press is driven by a motor in the same direction in which the direction of rotation of the ridges lies. Because the ridges 9 have a pointed shape, the walls of the juice-carrying cells of the fruit are torn open slightly in order to allow the fruit juice to drip out.
- shape of the element 2 is also suitable in the case of non-motorized and non-rotatable fruit presses.
