Fluid Bed Dryers
Hi-Tek Engineers offers Fluid Bed Dryer. The open and closed cycle fluid bed designs depending upon the desired product quality and other product variables. The feed is introduced into a fluidised layer of particles through which air is passed. The individual particles become suspended in the air at a given velocity. The drying process engenders a state wherein the particles are fluidised and the product layer gains flow-characteristics like a liquid. This can be effectively deployed for selective cooling of hot solids like sugar. Advantages: intimate contact of hot air and solids results in high heat transfer coefficient. This makes the drying system compact; mixing of solids leads to a nearly isothermal condition throughout the fluidised bed; no overheating of heat sensitive products because of special constructional features; lower capital cost; no mechanical moving parts, i.e., low maintenance cost; easy control of residence time, simple to adjust moisture content of dried product; and easy handling of the feed and the product.
