Description

Technical Field

This invention relates to an automatic knife apparatus operated with electricity and/or pressurized air which is used to cut food product preferably döner kebabs into slices, wherein it comprises a continuously rotating knife in the form of a disk hereon, slicing of food product is achieved by user's single hand, and adjustment of slicing thickness is also achieved with same hand.

Background Art

In prior art, knives operated with hand-power or electricity which are used for slicing of food products such as döner kebab are known. The most common one is a type with long cutting edge which is only operated with hand power. Slicing is very troublesome with this type of knife and also very hard job since keeping same slicing thickness requires special expertise. Therefore, electrical döner kebab knives are developed to keep slicing thickness always at desired level and to decrease substantially tiredness of user's arm.
In prior art, published patent and utility model documents No: GB2263629 , DE20311402U , DE4428541 , electrical döner kebab knives comprising electrical motor placed in a grip handle and cutting mechanisms with rotating knife attached thereon are disclosed. Food products such as döner kebab are sliced easily with these products and slicing thicknesses are easily adjusted. However, the disadvantage of these products is that user has to perform adjustment of slicing thickness with his other hand and/or with an adjustment apparatus that he holds in this hand. Since this requires stopping of cutting process, it causes time loss.
In prior art, published patent application No: GB2346798 discloses a different type of knife apparatus. System in said application does not have cleaning feature while disk knife operates. Also it does not have required sealing elements hereon.

Object of the invention

The object of this invention is to provide an automatic knife apparatus operated with electricity and/or pressurized air which is used to cut food product preferably döner kebabs into slices, wherein it comprises a continuously rotating knife in the form of a disk hereon, slicing of food product is achieved by user's single hand, and adjustment of slicing thickness is also achieved with same hand. Another object of the invention is to provide a structure in which waste materials accumulated around the knife in a rotating disk form during slicing process are scraped. Further object of invention is to avoid fluid emanating from food products during slicing to leak into apparatus of invention and to cause a short circuit of electrical parts or to prevent rust and waste solid material accumulation that obstructs working of mechanical parts by accumulating in the apparatus.
