EXPANSION OF PARTICULATE VEGETABLE MATERIAL

摘要

"Improvements Relating to the Expansion of Particulate Vegetable Material" There is disclosed an improvement to the separator of a tobacco expansion apparatus which overcomes a defect of the prior apparatus which resulted in the presence of lumps of highly toasted material in the expanded vegetable material emanating from the separator. The separation screen extends over the full gas flow cross-section of the casing of the separator at that side of the screen which faces the gaseous medium inlet of the separator.
