Tema Fluid Bed dryer for spray dryer. The two stage drying process is superior to the traditional single stage drying in terms of product quality and cost of production.
The two stage dryer consists of a spray dryer with an external shaking fluid bed placed below the drying chamber. The product can be removed from the drying chamber with a higher moisture content, and the final drying takes place in the external fluid bed where the residence time of the product is […]
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 flexibility, extrusion cooking produces an incredibly broad range of food products, most notably in the cereal, […]
Fluid bed or fluidised dryers. I often get the questions : What does fluidised bed mean? How does a fluidisation work? What is the purpose of fluidisation? Etc.
In a couple of chapters, I like to explain more about this technology/process and where the system can be used.
Automatic weir(s) 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 […]
