Incorporating Liquids Onto Solids

Incorporating Liquids Onto Solids

The mechanically fluidized bed allows for the uniform addition of varying percentages of liquids onto solids.

The liquid percentages can be as low as 0.5% by weight of the batch up to the maximum loading for each product. The liquids can be atomized using various nozzles located in the mixer body or a top mounted stack.

Liquids with higher viscosity can be introduced to the mixer through a nozzle using a gas to assist in atomization. Higher percentages of viscous liquids can benefit from the action of the high speed choppers to provide the dispersing action.

Depending on the products, a liquid loading of viscous liquids onto excipient powders can reach as high as 65%–75% of the batch weight, depending on the materials.
