Spray dryer working principle

The working principle of a spray dryer mainly includes the following steps:

Atomization

Centrifugal Atomization: The liquid feedstock is pumped to the top of the spray dryer and enters a high-speed rotating centrifugal atomizer. Under the action of centrifugal force, the liquid is thrown out from the edge of the atomizer in the form of extremely fine filaments or droplets. For example, in some industrial spray dryers, the centrifugal atomizer rotates at a high speed of tens of thousands of revolutions per minute, which can produce droplets with a diameter of several tens of micrometres to several hundred micrometres.

Pressure Atomization: The liquid is pressurized by a high-pressure pump to obtain high-pressure energy and then sprayed out at high speed through a specially designed nozzle. When passing through the nozzle, the pressure energy is converted into kinetic energy, causing the liquid to break up into small droplets due to the shearing force and impact force at the nozzle outlet.

Airflow Atomization: Compressed air or steam is ejected at a high speed (usually ≥300 m/s) from the nozzle. The high-speed gas stream and the liquid come into contact, and the liquid is torn into small droplets by the friction force generated by the large speed difference between the gas and the liquid phases. This method is particularly suitable for viscous materials.

Spray-Air Mixing

After the liquid is atomized into small droplets, it is immediately mixed with the hot air entering the drying chamber. The hot air is usually heated to a certain temperature (usually ranging from 100°C to 300°C or even higher, depending on the material being dried) by a heater before entering the drying chamber. The hot air is evenly distributed in the drying chamber through an air distributor to ensure that the droplets can be fully and uniformly contacted with the hot air, providing sufficient heat transfer conditions for the subsequent evaporation of moisture.

Moisture Evaporation

When the atomized droplets come into contact with the hot air, the heat is quickly transferred from the hot air to the droplets, causing the moisture in the droplets to evaporate rapidly. Due to the large specific surface area of the droplets, the evaporation rate is extremely fast. In general, within a few seconds to tens of seconds, most of the moisture in the droplets can be evaporated, and the solid content in the droplets gradually precipitates and forms solid particles.

Dry Product Separation

The dried solid particles are separated from the exhaust gas in the drying chamber. Commonly, a cyclone separator is used to achieve this separation. The exhaust gas carrying a small amount of fine powder enters the cyclone separator. Under the action of centrifugal force, the solid particles with a larger mass are thrown to the wall of the cyclone separator and fall to the bottom for collection, while the purified exhaust gas is discharged through the exhaust pipe by a fan. In some cases, additional dust collection devices such as bag filters or wet scrubbers may be added to improve the powder collection efficiency further and reduce environmental pollution.

Spray Dryer Advantages

Spray dryers offer several advantages, which make them a popular choice in many industries for drying liquid or slurry materials. Here are the main benefits:

Fast Drying Speed
Spray dryers can convert a liquid feed into a dry powder in a very short time, usually within seconds to minutes. This is because the liquid is atomized into tiny droplets, which have a large surface – to – volume ratio. For example, when drying a milk – based liquid, the small droplets can quickly lose their moisture content upon contact with hot air. The large surface area allows for efficient heat and mass transfer, enabling rapid evaporation of water or other solvents.

Product Quality
Uniform Particle Size: The atomization process in a spray dryer produces droplets of relatively consistent size. As a result, the dried products have a uniform particle size distribution. This is crucial for many applications, such as in the pharmaceutical industry, where consistent particle size is important for drug formulation and bioavailability. For example, when producing a powdered drug, the uniform particle size ensures that the drug dissolves and is absorbed in a predictable manner.
Minimal Heat Damage: The short drying time and the ability to control the drying temperature precisely help to minimize heat – induced degradation of the product. In the food industry, for instance, heat – sensitive substances like vitamins and flavors can be preserved. When drying fruit juices, the rapid drying process helps retain the natural colors, flavors, and nutritional content of the fruits.

3. Versatility
Wide Range of Feed Materials: Spray dryers can handle a diverse range of liquid and slurry materials, including solutions, emulsions, and suspensions.
