Spray Dryer Optimization H2O Optimization

Apr 06, 2015 A 5% increase in capacity on a spray dryer can have a very large return on investment. (Ambient humidity changes alone can affect the capacity up to 15% from winter to summer in some areas.) Here is a sample payback analysis: Average capacity: 3,000 lbs/hr. Annual hours of operation: 6,000. Powder price: $2.00/lb.

Factors to be considered in spray drying process

Dec 12, 2020 Specific gravity. Specific gravity is a factor to consider when working with fluids other than water. Specific gravity is the ratio of a fluid’s density in comparison with water. The specific gravity of water is always held as 1. Specific gravity helps to decide product. throughput in the spray drying operation.

There are four fundamental steps involved in spray drying (Broadhead et al., 1992; Filkova et al., 2006): (1) Atomization of a liquid feed into fine droplets, (2) Droplet-hot air contact (3) Evaporation of droplet water and (4) Recovery of the powder. In addition, the feedstock is normally concentrated prior to introduction into the spray dryer.
