Spray drying
Spray drying is a method of producing a dry powder from a liquid or slurry by rapidly drying with a hot gas This is the preferred method of drying of many thermally-sensitive materials such as foods and pharmaceuticals A consistent particle size distribution is a reason for spray drying some industrial products such as catalysts
The effect of sample drying temperature on marine
Particle samples collected off Woods Hole Massachusetts were immediately dried at 56C at room temperature or stored in a freezer until freeze‐drying Results show that oven‐ and air‐drying did not shift the bulk composition (i e carbon and nitrogen content and stable isotope composition) of POC in the samples relative to freeze
