The Rosinaire consists of a horizontal, cylindrical vessel containing a longitudinal rotor/paddle assembly. The vessel body is fabricated with external jacket sections through which flows the heat transfer fluid (steam, hot water, hot oil, cooling or chilled water). Radial paddles are fastened to the rotor shaft by means of locknuts. The orientation pitch of the paddles is adjustable in order to set the residence time of the solids within the vessel.

The Superheated Steam Dryer (SSD) consists of a closed loop system, where the solids are conveyed by superheated and pressurized steam. The drying steam is generated by the vapors from the solids, and is indirectly superheated by any high-level energy source.

An aricle reprinted from The Alcohol Textbook 5th Edition 2009 with permission from Lallemand Ethanol Technology and Nottingham University Press. The cereal grains used for starch-based ethanol production such as corn, wheat, barley, rye and grain sorghum (milo) typically contain from 50 to 75% w/w starch. Between 25 and 50% w/w of the grain remain after fuel ethanol has been produced. The 'whole stillage', containing both dissolved and insoluble nonfermentables and nondistillable microbial by-products, is rich in nutrients, fibre, protein, lipids and yeast and has traditionally been incorporated into animal feed rations. The dryhouse is where these valuable animal feed components are recovered from the ethanol production process. The sole purpose of dryhouse operations is to remove water from whole stillage in an efficient and mechanically reliable manner. This process yields a number of possible concentrated products.

With short residence times and various design options, these dryers are an efficient and economical choice for a wide range of solids. Flash dryers can be the most economical choice for drying solids that have been dewatered or inherently have a low moisture content. Also known as "pneumatic dryers," they are the simplest gas suspension dryers with the smallest footprint. A single operation combines the necessary mixing, and heat and mass transfer for drying a solid. Residence time is short, usually less than 3 s, producing almost immediate surface drying.

During the manufacture of starch from maize a yield of about 61% is obtained as clean starch. The remaining material is made up of a number of co-Products, which are a natural consequence of manufacturing starch, by the wet milling of Maize. The majority of this material is used for animal feed production and so the area where these products are processed is often called the Feedhouse.
