Detailed description
product description:
High-speed centrifugal spray dryer is drying process liquid
forming process and the most widely used in industry. Most suitable for
the production of powder from suspension emulsions, solutions, emulsions
and paste liquid, granular solid product. Thus, when the finished
product particle size distribution, residual moisture content, bulk
density and particle shape are in line with the precision standard, the
spray dryer is ideal for drying process.
Highlights:
1,
hot air and droplet contact: there is a sufficient amount of hot air
into the spray-drying chamber, the hot gas flow direction must be
considered and angle, and whether it is flow, countercurrent or mixed
flow, to ensure full contact with the droplet can be sufficient heat
exchange.
2, the atomization: atomized spray dryer system must
ensure a uniform droplet size distribution, which is essential. Because
in order to ensure that the passing rate of product quality.
3,
and the angle of the cone angle of the pipeline design: We get some
experience from the production data set nearly a spray station, and we
can share.
Features:
1,
spray drying speed when the material liquid is atomized, the surface
area increased significantly, with the hot air in contact with the
process, the moment can be 95% -98% moisture evaporation, drying time of
just a few seconds, especially for heat-sensitive materials dry.
2, the product has a good uniformity, higher fluidity and solubility, purity and good quality.
3,
spray dryer production process is simplified, easy to operate
controls. For moisture content of 40-60% (for special materials, up to
90%) of the liquid can be dried into a powder product, after drying
without crushing and screening to reduce the production processes,
improve product purity. For the size, bulk density, moisture, within a
certain range can be adjusted by changing the operating conditions, the
control and management is very convenient.
Product Process Demo:
working principle:
Spray
dryer for the open cycle and flow, centrifugal atomization. After air
drying medium early, medium efficiency air filters and filtered
according to the operating instructions drawn by the blower and then
heated by the heater into the spray-drying tower through the main HEPA
filters hot air distributor. After the liquid material in accordance
with an operation instruction peristaltic pump, atomizer into the
high-speed rotation, the centrifugal force is dispersed into small
droplets. In the primary spray drying tower, hot air with small droplets
in full contact drying by heat exchange with a product along a
particular path, then through a cyclone to achieve separation, the solid
material is collected, filtered and then the gaseous medium, and then
discharged . Spray the entire system easy to clean, no dead ends, in
line with GMP requirements.

Note:
The characteristics and thermal evaporation of water and the material
inlet, outlet temperature-dependent. When the outlet temperature of
90oC, its water evaporation curve shown above (for the selection of
reference), with product updates, relevant parameters to change without
prior notice.
Ordering Information:
1, solid-liquid names, properties: solid content (or water content), viscosity, surface tension, PH value.
2, after drying powder capacity, allow the residual water content, particle size, the maximum temperature allowed.
3, yield, the opening times of the day.
4, for energy: vapor pressure for the amount of capacity available for coal, oil, gas.
5, the control requirements: inlet and outlet temperatures need to be controlled.
6, to close powder requirements: whether you want to install the trap bag, environmental requirements for exhaust emissions.
7, other special requirements.
