Rotary oven, continuous

Continuous dryers, ovens, incinerators, and furnaces take any of a variety of forms such as rotary drum, tower, shaft, tunnel oven, multihearth (Herreshoff) kiln, and fluidized bed. As with all continuous furnaces, their design is very dependent on how the load(s) can be moved through the furnace (or occasionally, how the furnace can be moved over the loads). 

The extractions were carried out either with an automatic, continuous liquid-liquid extractor, or by three successive extractions in a separatory funnel. The benzene was removed in a rotary evaporator in vacuo, and the residual oligomer dried in a vacuum oven at a temperature below 50°C. Blank experiments were also run which showed that no artifacts were being produced.

The manufacture of LiFeP04 differs from that of the positive electrode materials discussed so far, although the method is still based on a solid-state reaction. An inert or reductive atmosphere is required. Therefore, the furnace construction is crucial. In the furnace, Fe + must be reduced to Fe + and the oxidation of Fe + to Fe + must be prevented. A rotary furnace for the manufacture of LiFeP04 is shown in Figure 5.15. It can control the atmosphere and is efficient for continuous mass production. Since it can rotate, the uniformity of the manufactured LiFeP04 is well controlled. In addition, its maintenance cost is very cheap compared with the traditional belt oven.
