Fluidized bed low temperature perfuming formula flavoring cylinder, including feeding mechanism, perfuming pipeline, stock guide and loose dust collector, feeding mechanism is including the the firsthigh -frequency vibration pipe tobacco conveyer trough and the 2nd high -frequency vibration pipe tobacco conveyer trough that from top to bottom set gradually, and the top of the first high -frequency vibration pipe tobacco conveyer trough and the 2nd high -frequency vibration pipe tobacco conveyer trough corresponds respectively and be equipped with the perfuming nozzle, and the perfuming nozzlesets up on the perfuming pipeline, is equipped with air -cooled radiator on the perfuming pipeline, the stock guide lower extreme sets up to the feeding mechanism lopsidedness, and loose dust collector lies in the 2nd high -frequency vibration pipe tobacco conveyer trough below, and loose dust collector includes conveying mesh belt and the air intake that lies in the conveying mesh belt below andcorrespond with conveying mesh belt. This device simple structure, it is little to make the bits of broken glass, practices thrift spices, and the perfuming precision is accurate, spices is applyed in the material, spices temperature rising even diffusion at the beginning to reach fine perfuming effect.
