Description:

The Mobile Minor Spray Dryer transforms a feed liquid into a dry powder in a continuous one step operation. The drying operation includes three stages:

a) Atomization of the feed liquid into a spray by using a two-fluid nozzle.

b) Contact of the atomized droplets with hot gas to promote evaporation. The hot gas enters the chamber through a proprietary ceiling gas disperser.

c) Separation of dried product from the gas in a cyclone and/or exhaust filter.

Proper feed liquid atomization into a fine spray results in a high droplet surface area. This is important because it allows evaporation to be completed rapidly and decreases the drying chamber size. The small droplets are most often produced by a two-fluid nozzle where compressed nitrogen creates the atomization, or alternatively by a rotary atomizer or single-fluid high pressure nozzle. During the evaporation stage there is an accompanying cooling effect on the droplets and the drying gas, and with a limited duration of the product in the chamber, heat damage of the product is prevented. The product is then conveyed to a cyclone for main product collection and the fines further conveyed to an exhaust filter. Exhaust gas is recycled, flowing through an outlet HEPA, solvent recovery stages, heating systems, and an inlet HEPA before re-entering the chamber and starting the evaporation process again. As slight variations in system pressure can occur, for example due to transient temperature fluctuations and instrument purges, nitrogen is added or removed from the process continuously to keep the overall system pressure

balanced.
