FL Series Fluidized Bed Granulator

Heated and purified air flows into the column by a suction fan, the pellet or powder will be in uniform fluid condition inside the column, use one set of filter bags to prevent the leak of powder, and discharge the evaporated water to get drying purposes. If add one more spray gun can spray the binder or active ingredient downward into the uniform fluid powder, whenever the powder is combined in granules will be dried to get the required moisture content.

Top Spray Fluidized Bed Granulator

The top-spray granulator agglomerates finer particles into larger, free-flowing granulate in a one-pot process. Ingredients are mixed and preheated by an upward flow of heated air. Granulation occurs by spraying liquid into the fluidized powder. The granules are subsequently dried with heated air. The top-spray fluidized bed granulator can also be used for top-spray coating, layering from liquids, and instantly. Special features include a selection of air distributors and one-pot processing.

Drying of Fluidized Bed Granulator

Warm air is blown through a perforated distributor to rapidly and gently dry the formulation until the required residual moisture content is reached. Moisture evaporated from the product is exhausted with the drying air. Special features include a selection of air distributors and short processing times.

With fluid bed systems, safety always must be considered the highest priority. Due to the static charge of the product, there always remains the risk of an explosive environment within the fluid bed chamber. The safety risk is heightened when solvents are used as the binding solution. Hywell machinery designs fluid beds to an over-pressure and the explosive situation (correctly termed “deflagration”) is contained within the fluid bed chamber. Hywell machinery also offers a vented design, which safely directs the over-pressure situation to an open, safe place. fluidized bed spray granulation technology is best machine for granulator.
