ABSTRACT:
Apparatus for grinding and straining food products such as fruits or vegetables so as to reduce them to a puree, comprises a working receptacle having a bottom wall and a side wall which are figures of rotation having a vertical axis. A sieve is provided, through which the interior of the receptacle communicates with the exterior. A mashing tool is secured for rotation to a rotatable shaft disposed on that vertical axis and is driven by a motor unit, the mashing tool comprising at least one blade having a frontal attack surface so as to form with the internal surface of the side wall, at least in the region of the end of the frontal surface and substantially over all the height of the sieve, a corner at an acute angle which opens in the direction of rotation. The receptacle further has a counter-wall which is removably mounted on the side wall and transversely to the vertical axis, and which is disposed above the blade, adjacent the upper edge of the blade so as to leave a small gap between itself and that upper edge, the counter-wall being formed by a ring having a central opening and carrying on its inner edge a downwardly extending skirt which extends over only a portion of the height of the receptacle, so as to form a pressure crown between the skirt and the internal surface of the side wall, while the blade comprises an internal edge of which one portion extends at least the length of the skirt.
