Spray drying technology 068 f14 - TDL

Convection spray dryers are used for production of powder products from a wide variety of liquids. Liquid properties relevant to spray drying are: solids content, density, surface tension and viscosity. High concentration of solutes in the liquid is desirable to increase dryer thermal efficiency. Liquid components should be thermally stable

Effect of the Outlet Air Reuse on Thermal Efficiency of

However, the rise of the inlet temperature can damage the product and, on the other hand, low outlet temperatures implies in a final product with high moisture content. Two types of efficiency are used to measure the spray dryer performance: the thermal efficiency and the evaporative efficiency, showed on Eq. (1) and (2) (Hall and Hedrick, 1971).

In this dryer design, the spray and the air are introduced at opposite ends of the dryer, with the atomizer positioned at the top and the air entering at the bottom. A counter-current dryer offers more rapid evaporation and higher energy efficiency than a co-current design.

Improving the energy efficiency of industrial spray dryers

Jan 01, 1986 In all spray dryers, the thermal efficiency, i.e. the amount of water evaporated for a given amount of heat, is dependent upon the temperature driving force across the dryer. The efficiency is increased by raising the temperature of the air entering the chamber and operating the dryer at an outlet temperature as low as the process will allow.

Jul 22, 2012 I took some Dawn liquid detergent and my toothbrush from my oil stain removal experiment, and as that experiment went through the rinse cycle, I washed this. A quick (30 second) brush through…and look at the water run now: Wow. I replaced the lint filter into the dryer and put in the next load into the dryer.

Improving the energy efficiency of industrial dryers

Only a fraction of the heat input to a dryer is used to evaporate moisture. The thermal efficiency is the ratio of heat absorbed in evaporation to the actual heat input. Efficiency values in the range 10 % to 60 % are found in industry depending on the degree of process optimisation and heat integration.
