Dust recovery hood.
A new dust recovery hood for vibrating fluid bed dryers and coolers
features a proprietary design that allows on-spec particles entrained in
the airstream to be captured and gently returned into the process for
recovery as finished product. Engineered with an expanding, tapered
profile that reduces the airflow velocity as the process air rises, the
unit cuts the volume of product lost as waste, boosts the ratio of
finished product at discharge per unit of input and supports dust
control efforts while reducing the size of the unit required to achieve
tile desired temperature and moisture content. Undersized fine particles
entrained in the airstream that need not be recovered for recycling may
be collected using a dust collector. Developed for drying foods, the
system is manufactured from stainless steel for food product contact.
