PROCESSING LINE FOR PRODUCING OF PROTEIN-VITAMIN FEED PRODUCT FROM DISTILLER'S SPENT GRAINS Russian patent published in 2007 - IPC C12F3/10 C12P7/06 A23K1/06 

FIELD: processing of distiller's spent grains into protein-vitamin feed product.

SUBSTANCE: processing line has main pipelines for feeding of distiller's spent grains and discharge of solid and liquid process products, vacuum pipeline, intermediate reservoir, dehydrator, ventilation chamber, cyclone, drier, evaporator, atmospheric condenser, intermediate reservoir for liquid processing products, apparatus for concentration of suspended filtrate particles, mixer, granulator, ready product collector, and packaging apparatus. Fan and air heater are positioned in front of drier for producing of hot air with different temperature of drying agent. Apparatus for concentration of suspended filtrate particles is formed as osmosis unit having semi-impermeable membranes with pore diameter of (20-30)·10^-10 m. Drier has casing made in the form of hyperboloid of rotation and is equipped with reflector located in its upper part and feeder and acceleration portion which are located in its lower part, said acceleration portion being designed for producing of gas suspension therein. Drier central pipe adapted for discharge of dried spent grains particles has flare portion and is designed so that its height may be adjusted.

EFFECT: simplified construction, favorable conditions for running of heat- and mass- exchanging processes between gaseous phase and material under process and, as a consequence, improved quality of ready product.
