Fluidized bed dryer
Fluidized bed dryer (also called fluid bed dryer) is equipment used extensively in the bulk industry to reduce the moisture content of powder and granules. The equipment works on a principle of fluidization of the feed materials. In the fluidization process, hot air is introduced at high pressure through a perforated bed plate. The wet solids are lifted from the bed plate and suspended in a [...]
Drying of Extruded food & feed products
Extrusion is a mechanical process in which food or feed materials are forced, under pressure, through a die opening to create products of a desired shape, size, and/or texture. In the case of food production, if the food is heated by external heaters during the process, it is referred to as extrusion cooking, a relatively new and advanced food processing technique. Due to its processing [...]
Fluid bed drying
Fluid bed drying is a process by which particles, typically greater than 100 microns, are fluidized and dried. For the material to become fluidized, the particulates are placed under conditions that cause it to behave like a fluid. In a fluid bed drying system, air is passed through a perforated distributor plate which provides significant air flow to support the weight of the particles. This [...]
Mineral Dryer – Tema Process Fluidized Bed Dryer
- High drying air temperatures, results in greater evaporation per square metre of bed and reduces the power consumption per tonne of dried product and improves fuel efficiency. - Heavy-duty construction, high-capacity capabilities. Lowest life cycle cost due to substantial savings in fuel consumption and maintenance costs. - Reduced wear-and-tear: High-amplitude and low-frequency fluidized conveyance easily handles abrasive products. Limestone • Diabase • Granite • [...]
Weir for controlling the bed height / residence time in Fluid Bed Dryers
Weir for controlling the bed height/ residence time in Fluid Bed Dryers: In an efficiently fluidized bed, the solid material like granules/powders or pellets, are fluidized by an upflow gas. The wet solids are lifted from the bottom and causes the solids to behave as a fluid. The air velocity is adjusted to keep the moving layer of material fluidized. At the end of the [...]
Saving energy with Evaporative Cooling on a Tema Fluid Bed Dryer
Fluid bed dryers work on the principle of fluidization, a process in which hot air is introduced into the spaces between solid particles. Each particle is in direct contact with, and surrounded by, the hot air – creating an efficient and uniform drying process. The material is dried in the first section of the machine and cooled in the second. Most minerals can be dried [...]
