High Speed Centrifugal Spray Dryer
Stainless Steel Customized Centrifugal Spray Dryer for Coffee
Extract Catalyst
Introduction
Product Description
Spray drying is the most wide applied process in liquid process
shaping and drying industry.The drying technology is most suitable
for producing solid powder or practical products from liquid
material,such as :solution,emulsion,suspension and pumpable paste
states.For this reason,the particle size and distribution of the
final products,residual water contents,mass density and the
particle shape must meet the precise standard,spray drying is one
of the most desired technologies.

Main Principle:
After air gets filtered and heated,it enters into an air
distributor on the top of the dryer.The hot air enters into the
drying room in a uniformly spiral form.Passing through the high
speed centrifugal sprayer on the top of the tower,the material
liquid will rotate and be sprayed into the extremely fine mist
liquid beads.Through a very short time of contacting the hot
air,materials get dried.The final products discharge continuously
from the bottom of the drying tower and from the cyclones.The waste
gas will be discharged from blower.
Feature:
High drying speed atomizes material into liquid,the surface of the
material increase greatly.It only takes few seconds to evaporate
95-98% water in a hot air flow.This is especially suitable for
drying the heat sensitive materials.
The final product has features of good uniformity,flow ability,and
solubility.It is in a high purity and quality as well.
The production procedure is simple,operation and control are
easy.For material contains 40-60% water(special material can
contain more than 90%),it can be dried into powder or particles
once a time.After the drying process,there is no need for smashing
and sorting,so as to reduce the operation procedures in the
production and to enhance the product purity.The product particle
diameters,losseness and water contents can be adjusted through
changing the operation condition whining a certain range.It is very
convenient to carry out control and management.
Application
