The invention relates to a system for aerating a liquid food product, wherein the system comprises a bubble generator (5) for generating bubbles in a liquid food product flow. The bubble generator (5) comprises a wall (23) having gas transmissive pores, which wall separates an air supply space (24) from the liquid food product flow, wherein an air supply (4) is provided for supplying air to the air supply space (24). The air supply (4) comprises an air drying device (7) for drying air, preferably dehumidifying air, to be supplied to the air supply space (24) and/or a container (8) containing pre-dried air, said container (8) being arranged for supplying dried air to the air supply space.
