| abstract |
The invention concerns a method for producing particles ( 20, 21 ) at least partly crystallized, under pressure, comprising reciprocal dissolving of at least one fluid under higher or slightly lower pressure than its critical pressure with at least one substance to be treated, in a dissolving zone ( 2 ), followed by rapid depressurization with at least one depressurizing means ( 12 ) downstream of said dissolving zone ( 2 ) so as to collect said particles ( 21 ), at least partly crystallized, in the collecting zone ( 3 ) located downstream of said depressurizing means ( 12 ), said substance to be treated comprising the butterfat. Said method is characterized in that it further consists in collecting particles ( 20 ) at least partly crystallized in the dissolving zone ( 2 ). The invention also concerns a device ( 1 ) for implementing said method. |
