Fluid Bed Technology Progress

The fluid bed processor was used as an efficient way to dry a product due to suspension of particles in the hot air stream. However, over the last 35 years, the development in the pharmaceutical industry and the proliferation of the batch fluid bed processing technology in other industries as food, polymer, detergent, etc., has provided the opportunity to use the batch fluid bed processor for granulation, coating of particles, and pelletization. The advances in the fluid bed can be attributed to several factors. The needs of formulators, the requirements of the regulators, and technological innovations from the manufacturers of these equipments are

The vertical movement is caused by the gap or slit air around the rotating disk, the gravitational force folds back the material to the center, and the centrifugal force caused by the rotating disk pushes the material away from the center. The granulation produced in the rotary fluid bed processor shows less porosity, compared to the
