Claims10
A method of making a beverage ingredient powder, the beverage ingredient powder being an agglomerated beverage ingredient powder comprising a median particle size (D50) of between 150 and 1000 microns and a density of between 250 and 950 g/l, wherein the percentage of particles having a largest dimension of less than 90 microns is between 2%-20%, and wherein the beverage ingredient powder comprises a porosity of between 0.1 and 0.8, the method comprising steps of:
- a) Fluidising a bed of beverage ingredient powder with the introduction of a gas;
- b) Spraying liquid droplets onto the fluidised bed of beverage ingredient powder;
- c) Drying the fluidised bed of beverage ingredient powder;
- and
- d) Cooling the fluidised bed of beverage ingredient powder,
- wherein the ratio of sprayed liquid droplet volume to beverage ingredient powder volume is between 1:99 to 1:9.
