Stillage evaporation & DDGS systems

Coordinate solids separation, thin-stillage evaporation, syrup blending and drying around a defined co-product specification. DDGS is a process system, not a general accessory; a molasses stillage route requires a different residue strategy.

Engineering scope

Whole stillage first separates into wet solids and thin stillage. Evaporation concentrates the thin stream into syrup; the selected proportion is blended with wet solids before drying to DDGS. A wet-feed route changes the dryer requirement and logistics.

The four-effect falling-film arrangement in the Indonesia design reuses vapor across effects. Its design must address distribution, fouling, clean-in-place access and condensate quality. Dryer exhaust collection and dust control belong in the same engineering discussion.

Set feed-product moisture, composition and storage requirements with the buyer. Close the water and solids balances before quoting dryer capacity. Corn, cassava and molasses residues differ: do not transfer grain protein assumptions or a DDGS route to every feedstock.
