FLUIDIZED BED REACTOR

摘要

The invention relates to a fluidized bed reactor for granulating and coating particles in very small amounts. Said reactor comprises an essentially conical product container, a filter housing with inserted filters disposed above the product container, and a lower housing part disposed below the conical product container and provided with a process air supply. The product container is provided with a sieve bottom (2) in whose center a two-component nozzle (8) is inserted that can be adjusted height-wise relative to the sieve bottom depending on the product to be treated and the type of process. At least one guide element (15) is associated with the sieve bottom, said element guiding at least part of the process air to the two-component nozzle (8) with a radial component.
