Manufacturer direct selling dzl****0 centrifugal spray dryer
The spray drying technology of the centrifugal spray dryer refers
to the method of spray, so that the materials are dispersed in the
hot gas flow in the form of droplets, the materials are in full
contact with the hot gas, the process of heat and mass transfer is
completed in an instant, and the solvent is quickly evaporated into
gas to achieve the purpose of drying. The technology can eliminate
unit operations such as evaporation, crystallization, separation
and crushing, and can be produced continuously and automatically
with stable operation.
The centrifugal spray dryer adopts this drying method. The
gas-solid two-phase contact surface area is large and the drying
time is short, generally 5 ~ *0 seconds. It is suitable for drying
heat sensitive materials. The product obtained by drying has good
performance, small particles, good fluidity and instant solubility.
The disadvantage is that the dryer has large volume and low heat
transfer coefficient, resulting in low thermal efficiency and large
power consumption.
What is the operating knowledge of centrifugal spray dryer?
Let's introduce the pre use inspection and operating procedures so
that we can correctly operate the centrifugal spray dryer and have
a further understanding of it.
1. Pre use inspection
(1) whether the pipeline connection is equipped with sealing
materials and whether the sealing performance is good.
(2) whether the sealing ring falls off and whether there is air
leakage during use.
(3) check the lubrication of fan, shut-off fan and atomizer to see
if they are well lubricated.
(4) whether the regulating butterfly valve at the fan inlet is
open.
(5) whether the connecting pipes of the feed pump are well
connected and whether the rotation direction of the motor and pump
is correct.
(6) it is forbidden to idle the feed pump to avoid damaging the
stator. After use, it shall be closed in time.
(7) check whether the steering of the atomizer is correct and
whether the water cooling is smooth.
2. Operating procedures
(1) start the fan, and then start the electric heating to check
whether there is air leakage. If not, preheat the cylinder. When
preheating, pay attention to close the valve at the blanking
port.
(2) when the inlet temperature of the drying chamber reaches **0 ℃
***0 ℃, open the centrifugal nozzle to make it rotate.
(3) when the nozzle reaches the maximum speed, turn on the feed
pump to add liquid material. Pay attention to the amount from small
to large until it is appropriate. The concentration of the feed
liquid shall be determined according to the drying nature of the
material.
(4) during the drying process, pay attention to the exhaust
temperature and ensure that it is a constant.
(5) after drying, collect the finished products, and then carry out
subsequent operations.
