<p>When sterilising a granulate or particulate material, steam is added to the material in order to heat it to sterilisation temperature and the material is maintained at that temperature for a necessary residence time. The material is agitated to a fluid state in the first chamber whilst it is heated by a supply of steam. After agitation and heating, the material is passed directly into a residence vessel from where the material is discharged after a desired residence time. The sterilisation is carried out in a plant which includes a housing (4), an intake opening (5) in the housing, a discharge opening (6, 7) in the housing and agitator means (2, 3) provided inside the housing for fluidising a granulate or particulate material. The housing (4) has an inlet (13) for the supply of steam to the material in the housing, and the housing discharge opening (6, 7) is attached to a vessel (10) for receiving material from the housing (4) through the discharge opening (6, 7). In a bottom region thereof, the vessel (10) has a discharge means (11) for the material in the vessel. The plant is insulated and/or heated.</p> |
