Apparatus for grinding a product initially in the form of granules, grains or suchlike, comprising: a receptacle to contain the product to be ground and provided with an unloading aperture; a fixed grinder; a mobile grinder connectable to a drive motor; a grinding chamber in which the fixed grinder and the mobile grinder are located and provided with a discharge aperture to discharge the ground product; the grinding chamber, the fixed grinder and the mobile grinder define a reception compartment, put in communication with the unloading aperture, and an unloading compartment, separated from the reception compartment by means of grinding teeth of the fixed and mobile grinders and put in communication with the discharge aperture; the grinding apparatus comprises at least a cleaning device, associated with the mobile grinder, and at least a control unit, provided with commutation means and associated with the drive motor so as to make said mobile grinder rotate in a first direction of rotation which is mainly for grinding or, alternatively, in a second direction of rotation for cleaning, opposite to the first direction of rotation and suitable to allow the discharge of ground residues present in the unloading chamber by means of the cleaning device (30).

A separation apparatus for separating an unwanted substance from an extraction target includes a forming unit configured to form a separation chamber through which the extraction target passes, and a suction unit communicating with the separation chamber in a direction crossing a passage direction of the extraction target and configured to suck air in the separation chamber. The forming unit includes an inlet for the extraction target, which communicates with the separation chamber, and an outlet for the extraction target, which communicates with the separation chamber, and the air is sucked from the outlet into the separation chamber by suction of the suction unit.

The device for grinding food grains such as flaxseed, includes a bulb rotatably within a bowl. The bulb and the bowl together delimit a functional area, a lower area of which includes a device for moving the grain to a lower area having teeth to grind the grain. There is a device for maintaining, between the bulb and the bowl, at the level of the functional area, a clearance to allow for the grinding of the grains and to avoid all contact between the bulb and the bowl at the level of the space. The space is formed so as to prevent any grains returning from the lower area to the upper area. The invention further concerns a mill equipped with such a device for grinding food grains.
