The PFB-L is a lab-scale R&D fluid bed system capable of performing, granulating, drying and coating processes in a single unit.
The PFB-L laboratory scale fluid bed system features a built-in air handling system for heating and dust collection. After the process, rotation of the product chamber enables easy powder discharge.
Flexible and Stable Multi Process
Drying
Drying is a simple and basic principle.Powder is contained in the lower vessel and heated air is passed through a fine mesh and into the container for the circulation of the targeted powder. Heated air passes through the powder, aerating it to promote rapid drying. The expelled air is then passed through an internal filter, and discharged to the outlet duct by the dust collector. Fluid bed drying guarantees short drying time.
Granulating [Top Spray]
This process makes granulates by spraying various type of liquids onto powder. Spraying is done from the top, the opposite side to fluidization. The multi head nozzle makes it convenient and easy to clean. Due to variance of the volume of the product or the size of the nozzle, the height of the Spray gun is adjustable.
Coating [Bottom Spray]
PFB provides multi process with a single machine. The Drying, Granulating and Coating process are possible with one machine. The coating option includes granulating. Spraying is done from the bottom, With the same method as fluidization. It is best for fine coating.The partition in the container guides the flow of product, from the center to the direction of fluidization. Conversion from top spray to bottom spray systems is possible with product container and spray change, only.
Safe Environment and Smart Maintenance
Inflatable Seal
Inflatable seal is inflated at filter housing, expansion chamber & etc and expanded when the air is supplied to the seal and provide a perfect closed system.
Filter Maintenance
The fabric bag filter is equipped in the filter housing and the filter is moved up and down by the wiring system with motor. The differential pressure displayed on the HMI screen so detect the filter blockage.
