Technology & Process
The waste is loaded into the sterilization chamber (by hand in small machines or by means of an on-board automatic loader) in its original packaging, in plastic or cardboard bags or boxes, and the lid is closed.
The rotor starts and accelerate gradually while the material becomes finely grinded and the temperature rises quickly to about 100 °C.
The heat generated by friction in the material causes the evaporation of the waste moisture and the temperature remains firm at the value of about 100°C.
Once all the moisture has been eliminated, the frictional heat causes the temperature of the material to rise up to 151°C.
STERILIZATION OR PASTORIZATION
The temperature of the material is held ﬁrm at 151°C during 3 minutes, under moist heat conditions, by mean of controlled water dosage.
The waste is sprinkled with water in order to lower the temperature of the material to about 100°C. A vacuum pump then lowers the temperature further down to 60°C adiabatically.
The treated material is unloaded by centrifugal force through the opening of a
servo-operated valve positioned at the bottom of the treatment chamber.
