Method for treating a food product of vegetable origin (100) in particular a fruit comprises the steps of pushing by means of a pushing device the food product of vegetable origin within a treatment cavity. This is defined between an internal surface of a fixed hollow body or stator (20) and an external surface having conical shape of a rotor (30) and has an inlet mouth through which the food product of vegetable origin is introduced within the same and an outlet mouth through which the treated vegetable food product exits the cavity. In particular the treatment cavity has a size which decreases going from the inlet mouth to the outlet mouth. It is furthermore provided a rotation of the rotor (30) within the stator (20) about a rotation axis (35). In particular the combination of the rotation and of the pushing that are carried out by the machines produce a partially crushing of the food product of vegetable origin within the treatment cavity.
