Lleal’s Fluid Bed Dryers are versatile equipment that allows to perform up to three processes depending on the accessories used: drying, encapsulation and granulation. Gas-solid fluidization is the levitation of a bed of solid particles by a gas whose main features are that the temperature at all points of the bed is constant and the heat transmission is highly efficient. Both features make the fluid bed dryer an excellent equipment for increasing particle size and subsequent, the reduction of moisture or volatile particles.
The operating mode of the equipment, with a large flow of dry air in circulation, allows drying at low temperatures in short time unachievable for the vacuum drying process.
The encapsulation and granulation are carried out by the inflow of liquid through a spray nozzle. In the encapsulation the coating enters from the bottom of the reactor and an inner tube is used, whereas in the granulation the binder enters from the top of the reactor. In both cases, when the liquid addition is completed, the process is finished as the drying is simultaneous with the additive inlet.. This feature allows to realize the encapsulation and the granulation in a times much smaller than its traditional counterparts.
The fluid bed manufacture by Lleal incorporates new control systems that allow to manipulate all parameters involved in the three processes and accurately determining the end of the process, avoiding overexposure.
Our manufacturing portfolio goes from 1-6 kg L to 400-800 kg of production.
