A new spray dryer supported with freely rotatable propellers enables more efficient drying of milk samples

A new type of spray dryer was developed for drying milk and the like efficiently. To this end, freely rotatable propellers powered with air-flow were placed in chamber to increase thermal efficiency product yield newly dryer. Milk samples dried both system a standard compare efficiencies yields each. It observed that had caused change flow direction air, decreased temperature walls, increased drying. Consequently, dryer, adhesion powder particles wall each other is significantly reduced, resulting more efficient
