A machine for making variegated ice cream or ice cream shake, comprises: a basic structure (1); one or more basic product mixing and freezing units (2), where each mixing and freezing unit (2) in turn comprises a processing cylinder (4) containing the basic product (3) and cooled by a respective refrigerating system and a stirring member (6) mounted inside the processing cylinder (4) and rotating to mix the basic product to prevent it from hardening and sticking to the cooled inside wall of the processing cylinder (4) and to transform the basic product into a basic flavour; a closing element (7) for closing the cylinder and provided with at least one outlet duct (8) leading to the processing cylinder (4) at one end and to an outlet mouth (27) at the other end; a shutoff device (9) for closing/opening the at least one outlet duct (8); one or more containment tanks (11), also mounted inside the basic structure (1), for corresponding food syrups (12), each containment tank (11) being provided with an outfeed pipe (17) and feed means (41) for feeding the food syrups (12) to the at least one outlet duct (8); a mixing chamber (14, which is located along the outlet duct (8) upstream of the outlet mouth (27), and inside which the basic flavour and the syrups (12) are mixed by means of a respective mixing member (19) mounted inside the mixing chamber (14) and driven in rotation by an actuator to make a product known as variegated ice cream defined by the sum of at least two between the basic product and the food syrups (12); a control unit (20) connected to the actuator of the mixing member (19) and configured to drive the actuator in such a way as to vary the rotation speed of the mixing member (19). |
