Ultra Filtration UF is an egg whites concentration process used before
drying during egg whites powder production.
Egg whites that are approximately 11% DM (Dry Matter), could be
concentrated to 22%, reducing volumes by 1/2.
For example: if we had 3000 liters/h egg whites we
would have 1500 liters/h of water extracted by the UF (Ultra
Filtration) and then 1500 liters/h of egg whites would be sent
to the dryer.
UF offers the following advantages:
·
increase of drying capacity for the same drying equipment
·
cost energy savings during drying process
