Slicing device for fruit and vegetables.

Conventional slicing devices consist of punches, rotary disks with 1 or 2 knives, planers, and feed-through grids.

With all devices, the peeled and pitted fruit must be processed in a second step. When punching and throwing through, no pulling cut is achieved and the cut surface is not smooth. When punching, throwing through and using the turntable, the following applies: The fruit can rotate and the slices become uneven, odd, and the core hole is no longer in the middle. Working by hand is very dangerous; the machine versions are equipped with many safety devices, are cumbersome and expensive. The fruit immediately breaks into slices and turns brown with the oxygen in the air. These devices only work to a limited extent with crumbly fruit.

Devices such as individual knives attached to peeling machines, which run straight through the fruit with the peeling movement, create a continuous band. This then has to be separated again in a second operation. No closed rings are created.

The invention specified in claim 1 is based on the problem of creating a disc cutting device which can work as a separate machine or can be retrofitted to other machines and has the following advantages:

The fruit should be cut into slices during the peeling/coring process. Fruit that is suitable for the corresponding machine

If the slice is too big, it should be cut to the right length straight away. The thickness of the slices should be adjustable. The cutting depth should be set depending on the use, this ensures that the slices hold together a little and no oxygen can get in until they are used. The cutting should be a pulling motion to give the slices the best possible surface. The cutting process should not put much strain on the fruit so that even crumbly fruit/vegetables can be cut. Other processing should be possible at the same time.

These problems are solved with the features specified in claims 1-5:

Protection claim 1: The rotating movement ensures that the slices are cut one after the other, whereby the slice on the fastening side is always cut less deeply during cutting than the one further away. The simultaneous rotation of the fruit results in a pulling cut - since only a few knives are working at a time, even fine slices can be cut from crumbly fruit.

Protection claim 2: Due to the longer blade, parts that are too long for the machine are cut off completely.

Protection claim 3: Mounting the knives on a shaft enables the complete replacement of the shaft with a different knife spacing/length.

Protection claim 4: The adjustable fastening of the slice cutting device to the machine body ensures that the slices either fall immediately or still hold together slightly in the core.

Protection claim 5: Since the blade set only requires part of a rotation, peeling can take place at the same time. In machines with several processing stations, further transport can take place in the area without blades.

One possible design is shown in sketch 1 (front view) and sketch 2 (side view). The blades (1) are attached to a rotating shaft (2) - the fruit (3) rotates in the opposite direction to the blades. The cutting process is carried out by pulling, slowly and one after the other towards the fastening side. The cut is perpendicular and even. During the gap (4) on the blade shaft, the fruit can be peeled or moved on without having to interrupt the rotation.
