Also,
Since the buttful plate is provided with a small gap between it and the punching plate, the processing air blown into the furnace chamber changes its flow direction at the buttful plate and flows along the buttfull plate. It flows downward from the end of the buff-full plate down the side of the processing material storage section. As a result, air flows between the processing materials due to the ejector action of the downstream wind, and the processing materials are uniformly heated or cooled.
