Most all oil mill are using cold water for hydrocyclone operation.
Recently we had try to use hot water with 80d c for hydrocyclone. Water source are from turbine cooling water, decanter flushing water and vacuum drier, all of the water been pump to hot water tank and use as press dilution and if hot water tank are full it will overflow to hydrocyclone.
The advantage are we able to reduce kernel silo drying retention time. PK moisture exit hydrocyclone are only 10% compare using cold water are 19%.
Which means only less energy are required to further dry it.
In terms of PK loss in hydrocyclone it still remain same.
