A fluid bed granulator is a piece of equipment used in the pharmaceutical and food industries to create granules from powders. It works by blowing air through a bed of powder, causing the particles to become suspended and fluidized. This process allows for even distribution of a binding solution, which helps the particles stick together and form larger granules. These granulators are efficient and provide uniform granule size, which is important for consistent product quality. They are often used in the production of tablets and capsules, ensuring that the final product has the desired properties for effective delivery and absorption in the body.
