Solidaire
Thin-Layer Indirect Paddle Dryer
Drying Done Right
The Solidiare’s proprietary paddle-drying technology offers the highest heat-transfer coefficient on the market. That means faster, more efficient drying; exact residence time control; and lower operating costs.
Fast, Efficient Drying
Thin-layer operation delivers high heat transfer along the jacketed vessel walls. That provides the most efficient thermal operation available, maximizing heat transfer and shortening drying times, all with a much smaller footprint than other dryers.
Residence Time Control
The Solidaire offers strict control over residence time, gas contact, temperature and shear to carry out difficult reactions. The adjustable paddle rotor provides the precise conveyance required to work through difficult transition phases.
Lower Operating Costs
The Solidaire is the most thermally efficient dryer available. It uses less energy; requires less overhead space; and is easier to adjust, maintain and clean than other dryers.
Advantages
High Versatility
Whether dry or wet solids, liquid, slurry, cake or paste, the Solidaire can process a wide variety of materials in multiple applications including drying, devolatilizing, reacting, cooling and crystallizing.
Small Footprint
Efficient, thin-layer design provides the most efficient thermal operation with a far smaller footprint than bed dryers or other direct dryers.
Simple Paddle Adjustment
Adjustable paddles control residence time and provide more control over material as it is processed.
Safe Processing
The Solidaire safely removes and recovers volatile organic compounds from solids. Volatiles evaporate under an inert environment to prevent dangerous operation.
Easy Cleaning
An optional split-body design provides quick access for easy cleaning.
Inline Injection
The optional Jet Rotor™ continuously injects gas or liquids directly into the material during processing for additional treatment.

How does it work?
The Solidaire consists of a jacketed vessel and a rotating shaft that runs the length of the vessel. Adjustable paddles are mounted on the shaft. The paddles can be adjusted for pitch and depth, providing fine control over material residence time and thickness.
Wet feed – such as solids, slurries, pastes, wet cakes or gels – is fed into one end of the Solidaire. The spinning paddles break up any loose agglomerates and then forces the material into a thin layer on the inside of the vessel.
The vessel walls are jacketed to accept a heated thermal media such has steam or hot oil, which indirectly heats and dries a thin layer of material as it is forced against the vessel walls. Thin-layer drying provides the most efficient thermal operation available, minimizing energy used while maximizing heat transfer without requiring a large footprint.
As the solids dry, vapor is produced. A heated counter-current gas steam conveys the vapor out of the Solidaire, through a filter, and into a condenser for collection and recovery.
For crystallization applications, a custom split-jacket vessel provides heating and cooling in a single unit. Material is heated in the first zone, then cooled in the second zone using a cooling media such as chilled glycol or water.
Finally, rotating paddles force the processed material through the Solidaire to be discharged for downstream processes such as cooling, milling or blending.
