A fluid bed granulator is a piece of equipment used in the pharmaceutical and food industries to create granules from powders. It works by suspending the powder in an upward flow of air, which fluidizes the particles, allowing for even mixing and coating with a binding solution. This process enhances the flowability and compressibility of the material. The granulation process typically involves three main steps: wetting, mixing, and drying. First, the powder is moistened with a liquid binder, then mixed to form granules, and finally dried to remove excess moisture. This method improves product consistency and quality, making it a popular choice for manufacturing tablets and other solid dosage forms.
