High Speed Centrifugal Spray Dryer
High speed centrifugal spray dryer for medicine food chemical
powder particle
Introduction
Description:
Spray dryer drying is the technology most widely used in the liquid
technology shaping and in the drying industry. The drying
technology is most suitable for producing solid powder or particle
products from liquid materials, such as: solution, emulsion,
suspension and pumpable paste states ,For this reason, when the
particle size and distribution of the final products, residual
water contents, mass density and the particle shape must meet the
precise standard, spray dryer drying is one of the most desired
technologies.
Work Principle:
High Speed Centrifugal Spray Dryer Series of LPG is gas-liquid
co-current flow drying equipment, using high-speed centrifugal
atomizer, the liquid will be atomized into fine droplets, then mix
with the hot air from the distributor in the dryer, heat and mass
transfer exchanges rapidly during the mixing process. In a very
short period of time the liquid become dry powdered products.
Production control and product quality control is convenient and
reliable. It is widely used in the drying production of different
types of liquids materials.

Product Characteristics:
1. Different types of solution, suspension, emulsion and cream
paste material can be dry for a one-time production.
2. The fog moment and fog droplet of spray-drying can be slightly
adjusted.
3. The hot air has been reasonable allocation, and the ceiling and
walls sticky situation has been eliminated.
4. It is suitable for the drying of thermo-sensitive and non
thermo-sensitive material at the same time. The product particles
are smaller than pressure spray dryer.
5. Simplify the production process, easy to use, good liquidity and
instant of the product.
Material to be dried:
1. Inorganic: aluminum nitride, zirconia, potassium fluoride,
bentonite, kaolin, barium sulfate, lead sulfate, sodium aluminum,
chromium oxide, titanium dioxide.
2. Macromolecule polymers: urea-formaldehyde resin, PVC.
3. Dyes: dispersol red FB, reactive dyes, etc.
4. Chemical Agents: silica dioxide, diatomite, sodium silicate,
wood calcium, sodium ligninsulfonate, naphthalene series water
reducer.
5. Pesticide: carbendazol chloride wettable power.
6. Food and feed additives: casein peptide phosphate, potassium
sorbate, fish serum.
7. Fertilizer: potassium humate, sodium humate.
