Patent ID: 8536356

Claim:
A process for preparing a fluid concentrated ingredient comprising crystals based on a fatty acid ester, comprising the following steps: preparing an emulsion comprising water, a compound based on a fatty acid ester, and surfactant(s), wherein the temperature of the emulsion is above the melting point of the compound based on the fatty acid ester, cooling the emulsion to a temperature below the melting point of the compound to form the crystals, wherein said cooling comprises introducing a stream of the emulsion into at least one cooling device, further wherein said cooling device is adapted to stir the stream by the stream's own flow, wherein the stream flows in at least one flow zone delimited by confinement walls and comprising static obstacles inside said flow zone, recovering a stream of a fluid comprising the crystals and the surfactant(s) downstream of the cooling device, optionally cooling the stream again, optionally adding other compounds to the fluid, diluting the fluid, and/or mixing the fluid, and recovering the fluid concentrated ingredient.
