Permeate powder spray dryer
In dairy processing, converting cheese whey and milk permeates into valuable powder forms is essential to optimize product yield and reduce waste. Traditional methods often fall short in handling ‘sticky permeates’ effectively and uniformly.

Efficiently produce non-caking permeate powders
