ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a turning device for food processors of the kind in which the processor is designed as a cutting machine for cutting or chopping the raw foodstuffs to be processed.
2. Description of the Related Art
Machines of this kind are available in designs for use in industrial kitchens and also in designs for domestic use.
A common feature of these machines is that they include a container which is fitted with a lid that has an infeed opening which allows raw foodstuffs to be inserted into the container while the machine is in operation. A tubular member which accommodates a driven shaft extends up from the bottom of the container. A cutting device is non-rotatably fitted to the shaft. The cutting device includes a sleeve-like central part which runs on the outside of the upwardly projecting tubular member and which carries the cutting tool at its lower end. The cutting tool may consist in one or more knives that extend radially outwards from the sleeve. The container is held stationary while the cutting device rotates, when the machine is in use.
One problem with food processors of this kind is that certain types of ingredients to be processed by the knives tend to fasten to the outer surface of the central part, causing the mass of ingredients to rotate together with said central part.
An example of such agglomerated masses is found in different types of meat that are to be chopped with the aid of the knives. For instance, meat that is minced tends to form a ball that sticks firmly to the outer surface of the central part and to the inner surface of the container. Consequently, the ball will only rotate around a horizontal axis to a relatively small extent.
This poor rotation of the ball means that the meat will be unevenly chopped. The poor rotation of the meat about a horizontal axis also means the disadvantage that the knives will cut through meat that has already been chopped, causing a local increase in temperature in the meat, which is highly disadvantageous with respect to the quality of the food prepared.
The same problem occurs with other types of food masses that can form a more or less sticky ball, such as fish mince, dough, etc.
The present invention solves this problem.
SUMMARY OF THE INVENTION
The present invention thus relates to a turning device for food processors of the kind where the processor is a cutting machine for cutting or chopping raw foodstuffs to be processed. The machine includes a container that is fitted with a lid, said container being stationary during operation of the machine. A tubular member extends up from the container bottom, and a driven shaft extends through said tubular member. A cutting device is non-rotatably mounted on said shaft and includes a sleeve-like central part on the outside of the upwardly extending tubular member, and carries said cutting tool at its lower end. The cutting tool includes one or more knives that extend radially outwards from the sleeve. The turning device includes at least axially extending strips of the outer surface of a sleeve member whose inner diameter slightly exceeds the outer diameter of the central part. The strips extend at one end thereof from a common holder. The turning device is adapted to be fitted to the central part in its position of use, with the holder facing upwards. The extension of the turning device in the length extension of the central part is such as to cover essentially the whole of the central part above said knives. The holder is adapted to be supported by the lid or a device connected with said lid, in the position of use of said holder, such that the turning device will be stationary while the food processor is operating, or will be rotatable relative to said container only to a limited extent.
