The Littleford DVT Polyphase® Reactor, which is a single apparatus that is designed to handle materials of varying composition which may pass through phases of liquid to doughy, to granular, to powder, and has the combined operational feature of pressure (250 PSIG @ 100ºF), vacuum 29.9" Hg. and effective heat transfer (heating or cooling).   
   
This Reactor operates according to the proven "fluidized bed" mixing principle whereby the materials being reacted are maintained in a mechanically fluidized suspended state, thus permitting the reacting mediums, gas-solid, or liquid-solid, to achieve intimate contact with each other and the heat transfer surfaces.   
   
The basic design of the Littleford DVT Polyphase® Reactor is a stationary horizontal cylinder, which is top loaded and bottom discharged. The standard tools are plow-shaped and radiate from a horizontal shaft that is supported by outboard bearings. Other mixing tool designs are also available. The basic mix action may be supplemented by high speed blending choppers that are positioned between adjacent plows for high shear applications. The shaft seals are double-faced, balanced, mechanical seals.
