Abstract
The invention relates to a system for aerating a liquid food product, wherein the system includes a bubble generator (5) for generating bubbles in a liquid food product flow. The bubble generator (5) includes 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) includes 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.
Claims19
A system for aerating a liquid food product, comprising:
- (i) a bubble generator for generating bubbles in a liquid food product flow, the bubble generator comprising a wall having gas transmissive pores separating an air supply space from the liquid food product flow,
- (ii) an air supply for supplying air to the air supply space, the air supply comprising:
- (a) an air drying device for drying the air to be supplied to the air supply space and/or
- (b) a container containing pre-dried air arranged for supplying dried air to the air supply space, and
- (iii) a controller configured to operate a valve to allow condensate to (a) drain passively during a liquid food aerating cycle and during standby of the system and (b) drain actively after the liquid food aerating cycle,
- wherein the air has a relative humidity below 70%.
A method for preparing a liquid food product, comprising:
- (a) drying incoming air and/or supplying the incoming air with dry air to produce dried incoming air;
- (b) supplying the dried incoming air to the liquid food product, and
- (c) controlling a valve of a system for aerating the liquid food product to allow condensate to (i) drain passively during a liquid food aerating cycle and during standby of the system and (ii) drain actively after the liquid food aerating cycle,
- wherein the air has a relative humidity below 70%.
