The present invention refers to a process of temperature controlled treatment of liquid and/or kneadable substances, such as an ice cream production, an ice cream material pasteurization, and similar, and to an apparatus for carying out said process. Said process comprises input of material to be treated into a container, agitating said material in the container by means of an impeller with simultaneous supply/discharge of heat by means of a cool/heat generator, continuous reading temperature of said material by means of at least one temperature sensor, and controlling continuously said cool/heat generator by means of said controller.
