Dry granulation is a process used in the pharmaceutical and food industries to create granules from fine powders without the use of liquid binders. This method typically involves compressing the powder into large sheets or slugs using a machine called a tablet press. The compressed material is then broken down into smaller granules, which improves the flow and handling properties of the powder. This technique is particularly useful for materials that are sensitive to moisture or heat, as it avoids the use of water or solvents. Dry granulation helps ensure uniformity in the final product, making it easier to formulate tablets or capsules with consistent dosage and quality.
