DDGS output requires installation of a drying unit, in which cake will be dried up to reaching moisturecontent of 10-12%. The drying process requires 3.0MW of heat. Hot air serves as a drying agent. Air isheated by hot-air generators. Installation of three hot-air generators is meant to be in the followingsequence:

• Lower-grade heat of CGU (54 - 47 ОС);
• Heat of distillery dregs centrate after decanter (70 - 50 ОС);
• CGU heat (90 - 70 ОС);

Saturated steam under pressure of 6bar is supplied to the inbuilt heat exchangers of the unit inorder to maintain high temperature in the housing of the drying unit. Steam under the same pressureis fed to the drying unit for steam smothering provision. Thermal capacity of hot-air generators arelisted in Table 7.3.1.
