In the processing apparatus described in Patent Document 1, since the scraping member is fixedly installed, smooth processing is performed when a large amount of processed material scraped from the inner peripheral surface of the casing accumulates around the scraping member. There was a risk that it would be impossible.
Moreover, since the scraping member is not provided in the processing apparatus described in Patent Document 2, there is a possibility that smooth processing cannot be performed when the processed material adheres to the inner peripheral surface of the casing.
