What is Spray Dryer
A spray dryer is a type of machine that converts liquid materials into solid powders, making the material easy to store, transport, and use. It supports handling various liquid materials such as slurries and suspensions and atomizes them into fine droplets. In a short time, the machine can evaporate the moisture of droplets by hot air. FANQUN’s sprayer dryer is widely used in various industries due to its high efficiency and stability.
Working Principle of Spray Dryer
- Step 1: Before drying the liquid, it must be firstly atomized into fine droplets. This step is mainly completed through the high-pressure nozzle of the spray dryer. It offers high pressure to atomize the liquid material completely and spray it into a drying chamber.
- Step 2: Fine droplets are fully mixed with hot air in the drying chamber. The spray dryer precisely controls temperature and airflow of the process, achieving rapid drying within a short time. The water of droplets is evaporated, while also ensuring their compositions do not be damaged.
- Step 3: After the moisture is evaporated, you can obtain dry and uniform solid powder. The spray dryer is also equipped with a cyclone separator or filter to separate the powder and air, obtaining the required products. While the air is then discharged.
Types of Spray Dryer
The spray dryer can be classified into three types based on its atomization methods, including pressure spray dryer, centrifugal spray dryer, and two fluid nozzle spray dryer. Learning their features may help you make a better purchase decision.
Pressure Spray Dryer
A pressure spray dryer relies on a pump with high pressure like a piston pump to force the liquid materials to 2- 25 MPa or higher. It offers strong pressure to help the liquid material through an extremely fine nozzle, atomizing it into droplets. The droplets then contact with hot air and are dried into solid powder. The pressure spray dryer can generate even and fine particles. It is widely used for flavors, milk powder, detergents, and more.
Centrifugal Spray Dryer
If your project involves materials with high viscosity or high solid contents, a centrifugal spray dryer is more suitable choice. It uses an atomized disc that rotates with high speed to handle liquid materials, while supporting generating different particle sizes. With the help of centrifugal power, the atomized disc can throw out the liquid material into fine droplets and dry them. The centrifugal spray dryer does not need nozzles, reducing clog issues. However, this type of spray dryer features large volume and requires relatively big printfoot.
Two Fluid Nozzle Spray Dryer
The two fluid nozzle spray dryer atomizes fluid materials through compressed air or steam, then mixes them with hot air thereby drying them into powder. It supports handling fluids with high viscosity and some suspensions. The powder generated by the two fluid nozzle spray dryers is extremely fine, which can reach 10- 50 μm. It is especially suitable for high value-added products, such as pharmaceuticals, advanced pigments, and nanomaterials.
Advantages of Spray Dryer
Excellent Product Quality
Products generated by the spray dryer feature excellent fluidity and uniformity. This machine can evaporate approximately 95%- 98% moisture of the fluid material and offer high speed of drying. According to the high-speed drying process, the spray dryer retains most of the heat-sensitive components in liquid materials. This can improve the purity of the product while also ensuring its flavor and nutrition. It is also made of 316L stainless steel to remove residual moisture below 0.5%, reducing effects to the raw materials.
Production Controllability
Some terminal products have various demands on the particle size, shape and fluidity of the product, and the spray dryer can meet different unique requirements. You can precisely control the particle size, bulk density, and moisture content of the product within a certain range. For different types of liquid materials, the spray dryer supports changing operating conditions to achieve precise control.
High Efficiency
Unlike the traditional drying methods, the spray dryer does not need crushing, screening, and other additional processes. It directly dries liquid materials with the supports of various power and hot air, reducing the process flow thereby significantly enhancing operation efficiency. The spray dryer also offers high-speed drying, and the drying time for a unit droplet only takes a few seconds or even a few milliseconds. In addition, it can achieve continuous production to improve the production capacity of the equipment.
Significant Cost-effectiveness
The spray dryer can dry liquids with high moisture content into solid powder, decreasing their volume and weight. This significantly saves your costs on transportation and storage and reduces loss caused by liquid deteriorations by extending the shelf life of the product. The spray dryer is equipped with energy recovery systems and supports customizable configurations to reduce operating costs by 25%. For expensive raw materials, the spray dryer can achieve high powder yield around 95% or higher, minimizing raw material waste.
Wide Applications
Whatever dilute solution or high-viscosity slurry, the spray dryer offers high flexibility to handle different materials. You can choose different types of the spray dryer to meet actual requirements. By adjusting the process parameters, it can be widely used in multiple industries. The spray dryer also obtains many international certifications to suit different applications such as medical, agriculture, and more.

| Pressure Spray Dryer | Small particle size, good flowability, low energy consumption | Food liquids, medium-to-high viscosity suspensions and emulsions |
| Centrifugal Spray Dryer | Wide range of adjustable particle sizes, not easy to clogging | Materials with high viscosity, high solids content, or fibers |
| Two Fluid Nozzle Spray Dryer | Support handling materials with high viscosity, high drying speed, easy to maintain | Low viscosity, heat-sensitive, high solids content |
- Core Parameters: You should also focus on the core performance parameters of the spray dryer to determine if the machine can meet your project demands. They mainly include temperature of the drying air, powder yield, energy consumption, efficiency, and more.
- Application Demands: Different applications feature various unique requirements and demands. For example, if your project involves the medical and food industry, you must determine the spray dryer to obtain cleanliness certifications. For the chemical industry, the spray dryer should also be equipped with an explosion-proof design.
- After-sale Service: It is better to choose famous and reliable brands and suppliers to ensure stability of the spray dryer. If your equipment fails, they can respond in time, reducing production loss caused by downtime. You can also choose the supplier that offers testing services to make a better purchase decision.
