A pitting and cutting process for fruit, in particular peaches, involves the coplanar insertion, inside each fruit, of right and left upper and lower cutting blades, reciprocally horizontally separating the blades, inserting in the fruit an upper and lower pitting knife, rotating the pitting knives around the pit, vertically displacing downward both the upper cutting blades and the lower cutting blades to complete the cutting of the fruit, returning the right and left upper cutting blades and the lower cutting blades, still in reciprocal horizontal separation, and reciprocally horizontally approaching the right and left upper cutting blades and the right and left lower cutting blades for repeating the process. The related machine is also described.

An electrical food preparation device including a drive mechanism (3) rotated by a motor and a working tool (4, 5, 6, 7) including a bushing that removably engages on the drive mechanism, the drive mechanism including a section provided with at least one drive ramp that mates with a complementary drive ramp carried by said bushing in order to rotate said working tool, the drive ramp having an inclination designed such that the rotation of the drive mechanism in the direction of rotation of the motor generates a force on the bushing that tends to keep it engaged on the drive mechanism, the drive mechanism also including at least one retaining surface (33) that comes into contact with a stop carried by the working tool when the drive mechanism rotates in the reverse direction, the retaining surface and the stop having shapes that mate each other to prevent the bushing from rising back up along the drive mechanism when the motor stops suddenly, wherein the retaining surface is provided on a different part of the drive mechanism from the section supporting the drive ramp.

A machine and method for recognizing and orienting fruits, especially peaches, for their automatic pitting, the machine has a fruit flight conveyor (1) up to a cutting station (6) in which a vertical cutting plane is provided, the fruit flights (4) being shaped with a number of recesses (7) in which fruits (P) are positioned with fruit suture plane thereof, containing a suture line (ls), being arranged vertically. A fruit recognizing station (8) is suitable to detect the position of the vertical suture plane, and to calculate an angle () between the suture line (ls) and the cutting line (lt), or to communicate information of non-detection. An orientation station (16) is adapted to receive information on the dihedral angle, and to control a respective gripping unit (17) to grip and rotate a fruit to a final position, or to remove from the fruit lane.
