LPG-5 model 1 to 2kgs electrical heater mini spray dryer for lab
use
Description
LPG-5 model 1 to 2kgs electrical heater mini spray dryer for lab
use is suitable for solution, suspension, slurry, paste material, etc.
Liquid material is atomized to small fog drops. And fog drops
contact with hot air directly in the drying tower. Moisture content
is evaporated instantly. So spray dryer features high efficiency,
high mass transfer area, and short drying time, in general it is
5~30 seconds. Operating temperature can be adjusted according to
actual situation, in general inlet air temperature is 150~500°C.
And its automation control degree is control, environment solution
environment can be solved.
Principle of work
Filtered air is transferred into hot air by passing through the
heater, and goes into the hot air distributor on the top of the
dryer, then goes into the drying room evenly,. At the same time,
liquid materials are sent to the centrifugal atomizer on the top of
dryer by the screw pump with stepless speed regulator, atomized
into tiny droplets which will contact hot air, then dried into dry
product within shortest time. The finished products will be
discharged from the bottom of the drying tower and from Cyclone
separator. Waste air is exhausted by Induced draft fan.

Spray Drying Stages
1. Atomizing: by atomizer, feed liquid is dispersed into even fog
drops.
2. Contact of fog drops and hot air: through air distributor, hot
air enters into drying chamber, fully mixing with fog drops and
moves at a certain rule(the contact way can be co-current flow,
adverse current, mixed flow)
3. Drying process: fog drops has big surface area, and appears
obvious ”grades” to hot air both in temperature and humidity, thus
strengthen the transmission process of “plastid caloric” moisture
of fog drops is evaporated very quick(within seconds to tens of
seconds)
