Machine for making liquid or semi-liquid products

A machine for making ice cream, comprising:

• a production unit comprising a processing container for processing a liquid or semi-liquid base product, defining a processing chamber and provided with a stirrer rotating inside the processing chamber;
• a thermal treatment system associated with the processing container for heating/cooling the processing chamber;
• a feed device for feeding an additional product;
• a first transfer channel configured to transfer the liquid or semi-liquid base product from the processing container to a dispensing section;
• at least one second transfer channel configured to transfer the additional product from the feed device to the dispensing section;
• a shutter movable between a closed position and an open position for, respectively, controlled opening and closing of the first transfer channel, and in which the second transfer channel is formed;
• a containing body in which the shutter is slidably movable along a direction of translation and having an abutment portion configured to receive a head portion of the shutter at the closed position;
• a drive and control unit;
• the machine being characterized in that the at least one second transfer channel is made internally of the shutter and in that it further comprises a heating device which is associated as one with the shutter in such a way as to heat the additional product inside the at least one second channel and which is connected to the drive and control unit to be controlled by it.
