Laboratory small spray dryer atomization drying process

The work of the spray dryer consists of three stages, using a spray dryer for fine spray or dropping any liquid feed during the atomization process, spraying contact and suspension of hot gas through a stream, allowing the evaporation of the liquid and removing the dried solids, atomized droplets in similar shapes and sizes
.

After Z, the dry powder material is divided into dry powder substances and collected
through the gas stream.

Omission of dry gases is now considered to meet environmental requirements and will then be emitted within the air, or it can be redistributed within the
system.

Emphasis options for atomization can use multiple types of spraying, including centrifugal type, sonic atomization nozzle, and air
.

Another common type of spray dryer spray atomization nozzle is hydraulic pressure
.

Here, the fluid is pressurized by a pump and then forced through the holes to divide the fine droplets
within the liquid.

The size of the hole ranges from approximately 0.
5 to 3 mm
.

As a result, a simple nozzle is defined as a solid content of about 700kg/h for the entire feed, which also depends on viscosity, pressure, size of the pores as well as a limited order
.

Discarding all the results of the query through the orifice in smaller droplets, and reducing the increased pressure on the particle size of any given feed stream, the nozzle needs to replace a smaller hole
.

It also requires more pressure from the pump in order to get the right amount of flow
through the injector.

Some large systems can have up to 50 nozzles, making it difficult to control the size of particles
.

The three methods of the spray dryer system D are aerosolized
in double fluid.

Where atomization is achieved, the interaction
of the environment created by the D body and the D body is often compressed within compressed air.

In this case, neither the pressure of the air nor the
liquid requirements are high.

Perhaps, a typical range of 200 to 350 kPa can do the job
.

The size of the particles is controlled by changing the overall proportion
of the compressed air flow of the liquid flow.

Spray dryer spray drying is a process applied in the liquid process
forming and drying industry.

Z is suitable for the generation of powdered and granular products in solutions, emulsions, suspensions and pumpable lake-like liquid raw materials
.

Centrifugal spray dryer is the use of centrifugal atomizer to dry some liquid materials, is currently one of the more used in industrial production of the
dryer.

Therefore, spray drying is an ideal process
when the particle size distribution, residual moisture content, bulk density and particle shape meet the J exact standard.

The design and selection of the atomizer of the spray dryer should be evaluated
on the basis of the properties of the liquid being dried, the particle size distribution and the quality of the prepared powder.

Spray dryer Z is suitable for generating powdery, granular or bulky solid products from solutions, emulsions, suspensions and plastic paste-like liquid raw materials
.

Therefore, when the particle size distribution, residual moisture content, bulk density and particle shape of the finished product meet the J exact standard
