Fluid Bed Dryer, Granulator, Coater:

Top Spray Granulation: Spray atomized binder or active ingredients on the fluidized to form the uniformity granules.

Bottom Spray Coating: The concept of Bottom Spray Coating is also known as Air Suspension Coating, is to separate pellets or granules from one another in an air stream and spray a coating binder onto the pellets or granules while they are suspended. When the hot air passes through the bottom screen of a container and draft tube (Wuster insert), it will generate the siphon principle. The granules will fall down and will be sucked into the draft tube (Wuster insert) again, while the bottom spray gun will spray towards top to achieve coating purpose.

Side Spray Powder Coating/Film Coating: The Side Spray is better for coating with high firm content. The cores (seeds) are placed on the turntable and hot air is blown upward between the turntable and the granulation area. The 

coating solution is sprayed on the rolling cores through the pump and spray gun. The process involves simultaneous coating and drying of the cores, the repeated actions achieve the desired coating thickness or granule size. Powder Coating is achieved by charging powder and spray binder at the same time.
