According to the process, the liquid product, for example mud, is homogenized and reheated to a temperature of 30-60 ° C. the reheated liquid product is allowed to flow at an overpressure of 2-4 bar and, by immediate introduction of a steam at a temperature of 130-151 ° C and pressure of 1-3 bar in the liquid product, the temperature thereof is brought to about 130-150 ° C in a period of 1-2 seconds, which causes granulation in the mud. The liquid product is then allowed to flow while maintaining its pressure and its temperature increase for a period of approximately 60-300 seconds. The liquid is then left in adiabatic expansion, reducing its pressure to approximately 0.01-0.02 bar for a period of 1-2 seconds. The expanded liquid is then separated into water, grease containing water and solid impurities as well as in a wet solid phase containing proteins. The installation is characterized by the fact that it has a means serving for reheating the liquid product as well as a pipe (18) serving for evacuating the heated liquid product, connected to the heating system (5). The steam line (20) opens into the latter. The pipe (19), in which an expansion valve (6) is integrated, leaves the heating system (5). A line (22) opening into the separation tank (7) is connected to the expansion valve. The installation has an apparatus used to separate the liquid product leaving the separation tank (7) in the aqueous, greasy and solid phase. |
