Technical analysis of a back supply of heated rendering-plant fat the disc drier

Abstract

The fulfilment of the subject of the Act No. 76/2002 Dig. on integrated prevention reduces energy consumption and increases hygienic safety of a thermal treatment of animal tissues at veterinary decontamination institutes. By making use of a back supply of heated rendering-plant fat to the continuous disc drier KDS 250 the so-called fritting effect is induced speeding up the evaporation of residual water and reducing the redrying time of the meat and bone paste. An analysis proved a reduced consumption of specific energy, whereby the demand for the best available technique (BAT) is met.
