	It provides for the extended residence time required for products such as modified starches and some polymer materials. P-type Ring Dryer is used for heat sensitive materials. In this configuration, the semi-dried particles discharged from the manifold are exposed to the outlet temperature level.

	It can be used for thermally stable products such as zeolites, silica, and precipitated calcium carbonate.		It can be used for thermally stable products such as zeolites, silica, and precipitated calcium carbonate.


	The Full Ring Dryer exposes the recirculated coarse particles to the inlet temperature level; the diagram demonstrates incorporation of a disintegrator. This type of dryer incorporates a centrifugal classifier (manifold) in the flash dryer loop. The manifold consists of a series of adjustable deflector blades which control the recirculation within the dryer. The manifold provides selective classification of the larger, wetter particles back to the drying duct extending The residence time. In addition, the manifold results in lower product moisture using lower outlet temperature than in a simple flash dryer.
