EnerDry has already examined the possibilities of drying distillers grain (DG) and distillers grain with soulbles (DGS) in the steamdryer.
A large scale test, on a sugar beet pulp dryer has been conducted, and it was a succes.
By installing a steamdryer on a ethanol factory, the steam produced in the steamdryer can for example be used in the beer column reboiler. This way all the energy used for drying is raclaimed.
A typical factory (60 – 150 million gallon / year) will be able to produce ethanol and DDGS at app. 20.000 BTU/Gallon when installing a steamdryer.
