hi,
That brings back memories of a boiled sweet de-flashing drum i built about 1980 with a very shallow angled washing machine drum on 4 casters inverted one of which was driven by a chain from the conveyer that came from the sweet punch machine.

The press processing the hot sugar rope left a very fine flash of sugar that when it was cooled was EXTREMELY sharp, the individual sweet was then transported on a chain mail conveyor belt with cooling air blast. The sweets were then dropped into my washing machine drum that "de-burred" the sweet by tumbling them.
