Centrifugal atomization of liquid feed followed by rapid hot-air drying.
High speed centrifugal spray dryer suitable for: solutions, emulsions, suspensions and pumpable slurries suitable for centrifugal atomization.
✅ Liquid-to-powder in one step — no crushing or screening
✅ 5–10s drying, ideal for heat-sensitive materials
✅ ≥95% powder recovery, GMP/SS316L optional, 5–10,000 kg/h evaporation
At the top of the drying tower, a high speed centrifugal spray dryer (8,000–25,000 rpm, disc diameters 50–340 mm) shears the feed into fine droplets that meet co-current hot air at 140–350 °C, evaporating most of the moisture within seconds at outlet temperatures of only about 80–90 °C — a thermal profile well suited to heat-sensitive products such as food flavors, enzymes, pharmaceuticals and natural colorants. Water evaporation capacity spans 5 to 10,000 kg/h across the model range, with powder recovery of ≥95%, SUS304/316L contact parts, steam, electric, gas or oil heating, and PLC + HMI automatic temperature control;
Liquid feed is delivered to the high-speed centrifugal atomizer and dispersed into fine droplets. Heated air enters the drying chamber, moisture evaporates rapidly during droplet contact, and the resulting powder is recovered from the chamber and exhaust-gas collection system.
