fast drying electricity/fuel/oil/gas heating Spray drying equipment
Atomizing drying machine is the high efficient drying equipment, to make dry powder or granule from liquid, emulsion, suspension and pumpable pasty liquid, especially for thermosensitive material, it can keep color, original flavor and chemical feature of raw material, and the finished dry powder or granule have good quality,purity, fluidity and solubleness.
This equipment features by high accuracy & speed & efficiency, simple production process, labor-cost saving, widely applied in the industry of chemical, food, pharmacy, biochemistry, light industry,etc.
Working Principle:
After filtering and heating, the air would enter into upper air-deployer of drying tower, and then come in in hot spiral form. At the same time, the raw liquid material would be atomized by tower from upper inside, become the super tiny globule in mist type, the surface of which would contact the hot air fully, then finished dry powder would be achieved in short time and collected at the bottom of tower and be discharged from cyclone separator, the gas would be exhausted outside.
Features:
- High drying efficiency
- The finished power or granule has good homogeneity, fluidity and solubility.
- Simple and convenient operation
- Mechanical atomizer is adopted, and driven by gear, speed is stable, which make sure the fogdrop is uniform.
- The direction and angle of hot air distributor is adjustable, which ensure the fogdrop fully contact hot air. .
- Conjunction elbow is made of sanitary degree steel pipe, smooth enough to avoide matereial blocked inside the pipe.
- Wide application: food, chemicals, ceramics, basic dyestuff, etc.

Some Operation Issues:
1. Atomizating: Atomizing system must insure uniform spraying fogdrops.
2. Hot airflow and fogdrops contacting: While the hot air come into drying tower, user have to consider the air flowing way and angle. No matter co-current flow, adverse current or mixed flow, user must insure the sufficient heat exchange, which is the key way to make sure the dry efficiency.
3. The angle design of pipelines and cone: It is pretty important to choose the suitable angle, please contact us for more working experience.

Application of machine
The spraying dry machine in customer's work plant:
♦ Package: wrapped with plastic film, packed inside the wooden case, and fixed with sea-worthy pallet ♦ Delivery: By sea / air / courier would be suppored according to buyer's location, just tell us where you wanna send and when you wanna get, the best solution would be suggested. |
- For better order, it would be appreciated if you can let us know the following item,
- what is the liquid like, physicalproperty: viscosity, PH, water content, surface tension, etc,
- the powder capaicty after drying, water content left, viscosity, max. temperature, etc.
- what is the producion capacity per hour or per day, your working hours,
- the heat resource avaiable, by gas, by electricity, fuel oil, steam, how much is it
- what is control model you like
- how do you like to collect the powder, the environment requirement for gas exhausted.
