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 gentle drying technique is an ideal way to evenly dry particulates to specific moisture content […]

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.

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 dryer, the same volume of solid runs over an overflow weir (this can also be a rotating […]

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 using evaporative cooling. Evaporative cooling means that the last part of the moisture is evaporated […]
