ABSTRACT A high quality animal feed stuff is produced by thermal de- watering of liquid stillage obtained from fermentation of grain raw material and distillation of the fermenta- tion product. The liquid stillage is mixed with partic- les of already dewatered product and the mixture is granulated in a granulation device to form essentially spherical granules with a dry substance content of 50-70 % by weight, the major part of the granules having a particle diameter in the range of 2-6 mm, whereafter the granules are dried by being conveyed as a porous bed in a control path in contact with hot gas of a tempera- ture less than 100°C, and whereafter a part of the dried granules with a desired particle size are dis- charged and the remaining part of the granules after possible desintegration are recirculated to the granula- tion step. Since all the dewatering is carried out by drying with a gas of low temperature, waste heat of low value such as condensation heat from air cooled conden- sors in the distillation plant can be used for drying the granules.
