Critical Dryer Components

With freeze-dryers used in production and also with pilot plants, all the critical plant components should be supplied redundant to make sure that the process can be continued if there is a mechanical or electrical failure. Redundancy is particularly advisable in the following cases ... 

One of the most critical components on the conveyor dryer is the product feeder or spreader. As in any convective drying system, it is imperative that airflow through the product be uniform. Convective heat and mass transfer is proportional to airflow velocity past the product.
