Standard Operating Procedure (PDF)

The Mini-drum Dryer is a custom-built apparatus for drying slurries. Wet material is applied in a thin layer onto the outer surface of the counter-revolving twin drums that are internally heated by steam.  After about 3/4 of a revolution from the point of feeding, the dried product is removed with a static scraper.  The drums are individually driven by a variable speed motor. This unit is effective for drying high viscous liquid, pureed, or paste-like foods.
