The object of the present invention is to provide a vegetable and fruit slicer and a method for slicing that with ease cuts difficult and/or hard vegetables as tomatoes, raw potatoes and raw carrots in nice slices.
The object is met by a vegetable and fruit slicer according to claim and a method for slicing vegetables and fruit according to claim. One advantage with the slicer and method according to the invention is that the usage of at least two sets of knives will assure that not all knives start cutting at the same time and stability in the slicing is achieved, resulting in even slices and an easy pushing movement.
This has an excellent effect on cutting tomatoes as the skin of tomatoes is very difficult to cut through and this feature will avoid compressing the tomato. This will also minimize the lateral pressure on the knives and thus less pressure need to be applied in the cutting direction. In this way it will be easier to cut through hard vegetables and fruits like raw carrots, potatoes and apples.
Another advantage with the present invention is that said at least two sets keep a constant lateral distance between the knives for each level of knives, which may result in that the sets incline in the same direction and with the same inclination, if the lateral distances between each level in each sets of knives is the same, i.e. if all the slices are meant to be of the same thickness, which of course is preferred.
Having these constant distances between the knives of each level will stabilize the slicing so that the slices will be more even in thickness and minimize the risk that the knives will cut obliquely or tend to curve thus cutting thicker and thicker slices or vice versa. Any arising obliqueness or curving will be compensated for by the other knife/knives in the same level of knives.
The knives in the sets of knives may for example be arranged in parallel so that the knives look like a stair or with angular displacement so the knives looks like a fan. The compensation of any arising obliqueness or curving may not be achieved if the stairs or fans incline in opposite directions, for example if the knives are arranged in V or wave shape.
Preferably the anvil part comprises an anvil with a corresponding recess for each knife in the knife part. In a preferred embodiment of the invention the knife part and the anvil part are swingably connected to each other via at least one hinge positioned transversally of the extension of the knives. This will give an advantageous angular motion enhancing the cutting. Preferably guiding means for guiding the knives into the recesses at use is/are provided at one of or at both the knife part and the anvil part.
In a preferred embodiment of the knives they have a toothed cutting edge. Preferably the cutting edges have non-linear form showing tops and valleys. In this way the teeth engage and start cutting at different moments and thus spreading the cutting in a corresponding way to have the knives in stairs. To achieve the best result each point of the tops has only one tooth.
A removable cleanser can be provided in the anvil having one rung positioned in each recess. Such a cleanser is a great advantage in practice for facilitating the cleansing of the anvil.
In a further embodiment of the present invention the knives are prestressed by pressure applied at the ends towards each other so that they are slightly bent in the direction of extension. Preferably, the knives are angled 5-15 degrees from their straight extension. This will even further minimize the obliqueness or curving of the knives during the slicing operation.
