METHOD AND DEVICE FOR DRYING BYPRODUCTS

摘要

The invention relates to a method and to a device for drying byproducts which are obtained during the treatment of raw materials containing starch and sugar, in particular after the fermentation and distillation thereof. According to the invention, the byproduct is fractionated in a clarifying phase having a high liquid portion and in a thickening phase. Said thickening phase is transformed, according to a conditioning method, into particles having a uniform geometry and said particles are dried in a pneumatic fluidised bed drying system having a relative intergranular void volume in the fluidised bed of between 0.5 and 0.92.
