Grinding appliance

An appliance for grinding oil-containing hard produce to extract an oily substance therefrom, comprising:

• first and second coaxial circular grinding members defining a grinding zone therebetween, the first member being rotatable about an axis with respect to the second member and is coupled to a driving unit for performing said rotation, each of the first and second members having respective first and second grooved faces facing the other on two sides of said zone, each of the grooved faces having an inner grooved portion and a peripheral grooved portion, defining, respectively, inner and peripheral grinding zones, the grooves on the inner grooved portion being configured to urge the produce towards the peripheral grooved portion, the grooves of the peripheral grooved portion having a different pattern than the grooves of the inner grooved portion;
• one of the first and second grinding members is formed with one or more feeding openings for feeding the produce into the inner grinding zone;
• a collection zone peripheral to the peripheral grinding zone for collecting the oily substance and channeling the oily substance to a substance collector;
• a peripheral wall that is peripheral to the peripheral grinding zone, wherein the collection zone is defined between the peripheral grinding zone and the peripheral wall, wherein the peripheral wall is circular and has a varying diameter along the axis direction between first and second diameters, the first diameter is selected to define a space from one of the grinding members to form the collecting zone, the second diameter is larger than the first diameter.

• one of the first and second grinding members is formed with one or more feeding openings for feeding the produce into the inner grinding zone;
• a collection zone peripheral to the peripheral grinding zone for collecting the oily substance and channeling the oily substance to a substance collector;
• wherein the one or more feeding opening is formed at a selected radial distance from said axis;
• and
• wherein said radial distance is closer to the periphery of the first or second coaxial circular grinding members than to said axis.

• a collection zone peripheral to the peripheral grinding zone for collecting the oily substance and channeling the oily substance to a substance collector;
• a capsule receptacle configured for receiving a capsule containing said oil-containing hard produce such that the content of the capsule is allowed to be fed into at least one of said one or more feeding openings;
• wherein the capsule receptacle is rotatable around said axis together with the first grinding member;
• wherein the capsule receptacle is coupled to an axle formed along said axis, said axle is coupled to a driving motor for being rotated thereby, the first grinding member is coupled to said axle for being rotated thereby.
