LPG series 100L Capacity Spray Drying Machine for Instant Coffee
Powder
Overview
1. Drying liquid or slurry materials into dry powder
2. Atomizing type: centrifugal atomizer
3. Evaporation capacity: 5-100 kg/h
4. Heat source: steam, electricity, thermal oil or gas/oil/coal
fired hot air generator
Working Principle
Spray drying is a method of producing dry powder from liquid or
slurry materials by rapidly drying with a hot gas. This is the
preferred method of drying of many thermally-sensitive materials
such as foods and pharmaceuticals.
Liquid material is pumped into the top installed centrifugal disc
atomizer by mono pump and atomized into fine droplets inside the
drying chamber. Meanwhile, clean hot air is blown into the air
distributor at the same time. The evenly and swirly distributed hot
air completely contacts with droplets for heat transfer. The
droplets are dried into powder in several seconds and sucked out
into the cyclone for discharging via exhaust fan.
LPG series spray dryer has been widely used in pharmaceutical,
chemical and foodstuff industry for drying liquid material into
fine powder.
Main Features
1) Particle size control: The dry particle size can be easily controlled by atomization of
the liquid feed and the design of the hot gas inlet. This spray
dryer can typically produce between 30 to 500 micron average
particle size, in a bell shaped distribution.
2) The evaporative cooling of product: The heat and mass transfer during drying occurs in the air and
vapor films surrounding the droplet. This protective envelope of
vapor keeps the particle at the saturation temperature. As long as
the particle does not become "bone-dry", evaporation is still
taking place and the temperature of the solids will not approach
the dryer outlet temperature.
3) Short residence time: The surface area produced by atomization of the liquid feed
enables a short gas residence time, ranging from 3-10 seconds
depending upon the application, which permits spray drying without
thermal degradation.
4) Flow properties of dry product: The shape of most spray dried particles is spherical, which
provides for fluid-like flow properties. This makes many downstream
operations, such as packaging, pressing, filtering, and handling
easier and less costly.
5) Size design of drying chamber: The size of drying chamber is specially designed to prevent
droplets sticking to the inner wall, dried powder accumulating on
the cone part and guarantee enough residence time.
