Device for hot filling of a container, comprising: a first fluid path ending with a dispensing nozzle; a first valve situated along said first fluid path and upstream of said dispensing nozzle; a second fluid path branching off from said first fluid path at said first valve; a second valve situated along said second fluid path; a first tank communicating with said first fluid path; sanitisation means of the dummy bottle type; characterized in that the sanitisation means are movable at least between a first position in which they are beneath said dispensing nozzle and the outlet of said second fluid path so as to receive the fluids coming from the first fluid path and from the second fluid path, and a second position in which they are set away from said dispensing nozzle and are beneath the outlet of said second fluid path; and in that said hot filling device is configurable at least in: a filling status in which the first tank contains a food fluid, the sanitisation means are in the second position, the first valve is open so as to allow the food fluid coming from the first tank to arrive at the dispensing nozzle and the second valve is closed; a sanitisation status in which the first tank contains a sanitisation fluid, the sanitisation means are in the first position, the first valve is open and the second valve is open so as to allow the sanitisation fluid coming from the first tank to arrive at the sanitisation means both via the dispensing nozzle and via the outlet of the second fluid path; a recirculation status in which the first tank contains the food fluid, the sanitisation means are in the second position, the first valve is closed and the second valve is open so that the food fluid returns to the first tank via a closed path passing through the sanitisation means and a further fluid path (13, 14) developing from said sanitisation means to said first tank. a first fluid path ending with a dispensing nozzle; a first valve situated along said first fluid path and upstream of said dispensing nozzle; a second fluid path branching off from said first fluid path at said first valve; a second valve situated along said second fluid path; a first tank communicating with said first fluid path; sanitisation means of the dummy bottle type; characterized in that the sanitisation means are movable at least between a first position in which they are beneath said dispensing nozzle and the outlet of said second fluid path so as to receive the fluids coming from the first fluid path and from the second fluid path, and a second position in which they are set away from said dispensing nozzle and are beneath the outlet of said second fluid path; and in that said hot filling device is configurable at least in: a filling status in which the first tank contains a food fluid, the sanitisation means are in the second position, the first valve is open so as to allow the food fluid coming from the first tank to arrive at the dispensing nozzle and the second valve is closed; a sanitisation status in which the first tank contains a sanitisation fluid, the sanitisation means are in the first position, the first valve is open and the second valve is open so as to allow the sanitisation fluid coming from the first tank to arrive at the sanitisation means both via the dispensing nozzle and via the outlet of the second fluid path; a recirculation status in which the first tank contains the food fluid, the sanitisation means are in the second position, the first valve is closed and the second valve is open so that the food fluid returns to the first tank via a closed path passing through the sanitisation means and a further fluid path (13, 14) developing from said sanitisation means to said first tank.
