摘要

Poultry droppings or similar pasty materials are dried and conditioned in two stages in the same vessel. In the first microbiological stage, the droppings are placed on elements carrying selective aerobic microorganisms to create optimum conditions. When the temp. drops, the second (flow-through) stage uses a many times greater air flow rate to dry out the material.
