An improved process for drying of Wet Solids and Condensed Distillers Solubles from starch based ethanol distillery to obtain Dried Distillers Grain Soluble (DDGS), the said process comprising: a. Subjecting the whole stillage containing solids after fermentation and alcohol distillation to decanter to separate wet solids and the thin stillage, b. Concentrating thin stillage using integrated evaporator and steam evaporator combination to obtain CDS of 30% to 50% w/w, c. Mixing the DWG and CDS with dry DDGS to obtain a blend with∼60° as angle of repose and 45 % to 60% solids, wherein the DWG and CDS from starch based ethanol distillery is dried using a two stage dryer; d. Subjecting the blend of step (c) to a first stage steam tube bundle rotary dryer for intermediate drying using low pressure steam at 3.5 to 6 bar g and material temperature of 85- 95°C, wherein the first stage steam tube bundle rotary dryer consists of a bundle of horizontal tubes through which the steam is passed and the DWG, CDS and DDGS blend is circulated for drying by rotating the dryer at a speed of 1 to 4 RPM, e. Mixing of semi dried DDGS with CDS and dried DDGS to obtain a blend of approximately 20% to 40% solids or preferably 22% to 35% solids w/w prior to second stage, f. Subjecting the first stage blend of semidried DDGS, CDS and dried DDGS to spin flash dryer/pin mill type flash dryer, wherein the drying is using hot air at a temperature of 90-150°C and collecting the dried DDGS without any hard lumps of size more than 2 to 3 mm size in a silo using conveying system, g. Cooling the dried DDGS at 25-35 °C by spreading in the storage area or subjecting to cascade type air cooler and bagging for transport to end users. a.
