DW series low-temperature spray dryer
Product details: DW series multi-stage fluidized spray granulation drying equipment
General description
Researchers are all along beset by the problem of rapid drying of
thermo-sensitive materials, as common vacuum drying and spry drying
will result in serious damage to biological activity or structure
of materials, long time of freeze drying, low energy efficiency,
and regrinding of massive material after drying. By long-term
practice and study, researchers have realized that low-temperature
spray drying can effectively solve the drying problem of
thermo-sensitive materials, and have elaborately developed the new
type low-temperature spray dryer, which is combined with advantages
of laboratory spray dryer and vacuum dryer, and available for rapid
drying (1 second) of materials under an inlet air temperature
around 80℃. It has provided an easy and safe method for drying of
thermo-sensitive materials, and is known as the dedicated equipment
for drying of emulsion, suspension, paste, solution and other
liquids. It is particularly suitable for drying of polymer, resin,
fuel, pigment, ceramics, glass, rust remover, insecticide,
carbohydrate, dairy product, detergent, surfactant, fertilizer,
organic and inorganic compounds.

Operating principle
Air enters through the filter and heater into the air distributor
at the top of dryer, and hot air is spirally and evenly led into
the dryer. The feed liquid in the tank is pumped through the filter
into the centrifugal atomizer at the top of dryer for spraying into
small vaporific droplets, which, in contact with hot air in
cocurrent flow, are rapidly evaporated and dried into the finished
product in a very short time. The finished product is discharged
from the bottom of drying tower and cyclone separator, and exhaust
gas vented by the fan.
Technical characteristics
(1) The whole experimental process of spray drying is completed in
a vacuum environment; the drying temperature of material is greatly
reduced, and the spray drying problem of thermo-sensitive materials
solved.
(2) Operation by large color touch screen: Heating temperature is
under PID control, and the feed rate of peristaltic pump can be
regulated at any time.
(3) Imported Oil-Free Air Compressor is installed, the sprayed
particles have a normal distribution of size and good liquidity,
and the operating noise is very low in compliance with the national
noise standard for laboratory.
(4) The product has good dispersibility, liquidity and solubility,
and the size, density and moisture content can be regulated in
certain ranges.
(5) To meet the requirements for adjustment of various parameters
in the scope of experiment, the real-time PID control technology is
adopted for control of drying temperature in the whole range at an
accuracy of ±1℃.
(6) Feed rate can be regulated by the peristaltic pump; the rated
handling capacity is 800 mL/h.
Applications:
Chemicals: Catalyst, resin, synthetic detergent, grease, ammonium
sulfate, dye, dye intermediate, silicon dioxide, graphite and
ammonium phosphate etc.
Food: Amino acid and analogues, condiments, protein, starch, dairy
products, coffee extract, fish meal and meat extract etc.
Medicine: Chinese patent medicine, pesticide, antibiotics and
dissolved medicines etc.
Ceramics: Magnesium oxide, porcelain clay, metalic oxides and
dolomite etc.
Spray granulation: Spray granulation: Aluminum oxide, ceramic
powder, pharmaceuticals, extra hard steel, chemical fertilizer,
granular detergent and Chinese patent medicine.
