Spray drying has been applied for many years for production of fine powders of high quality for various types of batteries. Over the years, the demand to energy density and performance of batteries from new applications has led to the development of new generations of batteries, including secondary lithium-ion batteries. These batteries are foreseen to play an important role in the electric vehicle market...

Drying as a process is one of the most energy-intensive unit operations on the planet. Add to that the fact that dryers are used extensively throughout the chemical process industries (CPI) and it becomes obvious that there ought to be more attention paid to reducing the energy consumption and upping the “green” ante of drying processes. Unfortunately, the current economy is putting any such...

This photo shows a spray dryer with a heat recuperator. The plant has an evaporative capacity of 1,825 kg/h Spray drying is one of the major industrial drying technologies. It is applied by many industries because of its ability to convert a liquid product into a dried powder in a lenient single step and because it allows you to control temperature and the particle formation process very accurately...

Evaporation of moisture or volatile organic compounds (VOCs) from bulk solids usually takes place in two stages: one in which the drying rate is constant, and the second in which the rate decreases over time. Devolatilization during the first stage is rapid and can be readily accomplished in flash, spray, or fluidized bed dryers. In the second stage, however, the VOC or moisture removal rate is diffusion...

After several years of proven operation in the food- and nutritional-products industry, a patented drying technology is now ready to be applied for any liquid or slurry product. Developed by MCD Technologies, Inc. (Tacoma, Wash.;, the Refractance Window (RW) system is said to cost about one third as much as freeze drying equipment, and consumes about one third to half the energy...

    Provided that they are updated when appropriate to keep them relevant, time-tested heuristics rules based upon experience, also referred to as rules of thumb, can be useful for the design, specifying and operation of several kinds of equipment used in process plants. The first and foremost heuristic rule is that the engineer should not shy away from using heuristics - and the second rule is...

    Process small batches with this fluid-bed dryer The Circular Vibratory Fluid Bed Processing System (photo) dries small batches of bulk-solid materials at high temperatures. The self-contained system integrates an 18-in.-dia. fluid-bed processor with heater, blower, cyclone separator and controls, ready for connection to a material inlet/outlet and power source. Intended for small volume...
