Abstract:
A vibratory fluid bed dryer apparatus having a housing with upper and lower ends, and a mechanism for vibrating said apparatus, comprising a dry powder outlet element, an air intake element defined by the housing and proximate the lower end thereof for enabling the entry of heated air, a material inlet port defined by the upper end of said housing, an air outlet port defined by said housing and proximate said material inlet port, an upper deck and a lower deck spaced from each other and located between said air intake element and said material inlet port, said upper deck including a screen, defining a plurality of very small apertures which creates a pressure drop from below said upper deck to above said upper deck, a one-way valve mounted on said upper deck and extending downwardly to above said lower deck, enabled by said pressure drop, to move the material from above said upper deck to said lower deck and out through said dry powder outlet element, whereby the air flowing upwardly from below said lower deck to and through said upper deck is prevented from blocking the downflow of material in the apparatus.
