a second transfer channel configured to transfer additional product from a feed device to the dispensing section; a shutter movable between closed and opens positions for controlling 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 and having an abutment portion configured to receive a head portion of the shutter at the closed position; a drive and control unit; the second transfer channel being made internally of the shutter and, a heating device associated as one with the shutter to heat the additional product inside the second channel and connected to and controlled by the drive and control unit. ## Claims ### Claim 1 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. ### Claim 2 (depends on 1) The machine according to claim 1, wherein the heating device is an electrical device and is configured to promote fluidification of the additional product, the heating device being integrated in the shutter. ### Claim 3 (depends on 2) The machine according to claim 2, wherein the shutter comprises a pair of electrical connectors for connecting the heating device to an electrical energy source. ### Claim 4 (depends on 1) The machine according to claim 1, wherein the at least one second transfer channel extends inside the shutter along the direction of translation and leads out at the head of the shutter and wherein the first transfer channel leads out at a side portion of the shutter. ### Claim 5 (depends on 1) The machine according to claim 1, wherein the at least one second transfer channel extends along an at least partly vertical direction between a first end, connected or connectable to the feed device for feeding an additional product, and a second end directed towards the dispensing section. ### Claim 6 (depends on 5) The machine according to claim 5, wherein the at least one second transfer channel has, at its first end, a connector connectable to the feed device for feeding an additional product. ### Claim 7 (depends on 5) The machine according to claim 5, wherein the at least one second transfer channel is connected, at its first end, to a socket for receiving a capsule of additional product. ### Claim 8 (depends on 1) The machine according to claim 1, wherein the containing body comprises a dispensing outlet located at a side or bottom portion of the containing body and defining the dispensing section; the dispensing outlet being closed by the shutter in the closed configuration and being opened in the open configuration of the shutter. ### Claim 9 (depends on 1) The machine according to claim 1, wherein the at least one second transfer channel is made of metallic material. ### Claim 10 (depends on 1) The machine according to claim 1, further comprising a cleaning device configured to remove encrustations of the additional product in the at least one second channel, the cleaning device comprising at least one cleaning means inserted or insertable into the second transfer channel to mechanically remove the encrustations of the additional product inside the at least one second channel. ### Claim 11 (depends on 10) The machine according to claim 10, wherein the cleaning means comprises a brush-like element. ### Claim 12 (depends on 10) The machine according to claim 10, wherein the cleaning means comprises a rigid scraper. ### Claim 13 (depends on 10) The machine according to claim 10, wherein the cleaning means has an outer contour that is substantially shaped to match the inner contour of the at least one second transfer channel and/or is insertable with a shape coupling into the at least one second transfer channel.
