WKS brand Chemical material hydrolyzate corn liquor glucose spray
drying machine
High Speed Centrifugal Spray Dryer
Introduction
The spray drying is the technology widely used in the liquid
technology shaping and in the drying industry. The drying
technology is most suitable for producing the powder, particle or
block solid products from the materials, such as: solution,
emulsion, soliquoid and pumpable paste states. For this reason,
when the particle size and distribution of the final products,
their residual water contents, the stacking density and the
particle shape must meet the precision standard, the spray drying
is one of the most desired technologies.
Application
Food and plants: oats, chicken juice, coffee, instant tea,
seasoning spices meat, protein, soybeans, peanut protein,
hydrolysates and so on.
Carbohydrates: corn steep liquor, corn starch, glucose, pectin,
maltose, potassium sorbate, and the like. Chemical industry:
battery raw materials, basic dye pigments, dye intermediates,
fertilizer, formaldehyde silicic acid, catalysts, agents, amino
acids, silica, and so on.
Ceramics: alumina, ceramic tile materials, magnesium oxide, talcum
powder and so on.

Principle
Spiral-shaped hot air evenly into the drying chamber. By passing
through the high-speed centrifugal spray at the top of the tower,
the material liquid will rotate and be sprayed into the extremely
fine mist liquid beads.Through the very short time of contacting
the heat air,the materials can be dried into the finished products.
The finished products will separator. The waste gas will be
discharged from blower.
Features
At a high speed of drying, after the spraying of the liquid
material , the surface area of the material will be increased
greatly. In the hot-air flow, 95%-98%of water can be evaporated at
a moment. The time of completing the drying needs only several
seconds.
Products with good uniformity, mobility and solubility, high
purity, good quality.
The production procedures are simple and the operation and control
are easy. The liquid with the moisture contents 40-60%(for special
materials, The contents may reach 90%).can be dried into the powder
or particle products once a time. After the drying, 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, looseness and water contents can be
adjusted through changing the operation condition in a certain
scope. It is very convenient to carry out the control and
management.
