Glass-lined double conical dryers are a workhorse in the pharmaceutical and fine chemical industries, with a rigorous design that enables them to run for decades. A common issue with these units, however, is the vessel's cleanability.

This blog post features a case study that illustrates how an upgrade to the dryer vacuum tube can accomplish all of these improvements.
