What is Pressure Spray Dryer
A pressure spray dryer relies on a pump to offer high pressure, atomizing liquid materials into fine droplets, which can be dried by hot air. The hot air offers high speed to evaporate the droplets, thereby improving drying efficiency. Due to its high drying speed, stable product quality, and other unique advantages, the pressure spray dryer is widely used for various industries.
How Does the Pressure Spray Dryer Work
Learning how a pressure spray dryer works can help you better know its features and advantages, thereby making wise purchase decisions. Its working principle can be typically divided into the following three steps:
- Step 1: Before the formal drying process, the liquid materials are firstly pressurized by a high-pressure pump to 1- 10 MPa. Then the liquids through a nozzle to be atomized into extremely fine droplets. The atomization level is directly connected to the final product features, such as particle size, shapes, and more.
- Step 2: The droplets then are evenly introduced into a large drying tower, which has been preheated. The droplets contact with hot air in the drying tower and its water content evaporates rapidly within a few seconds to a few percent. This high-speed drying process efficiently preserves active and heat-sensitive components of raw materials.
- Step 3: After the drying process, most of the dried powder settles at the bottom of the drying tower. While a small amount of extremely fine powder is carried away by the separation system. This system offers high efficiency to collect final products and remove the exhaust gas, achieving a high recovery rate that can reach 96%- 98％ or higher.
Key Components of Pressure Spray Dryer
- High-Pressure Pump: The high-pressure pump of a pressure spray dryer determines atomization effects. It is typically made of stainless steel or high-strength alloys to meet different material demands. The high-pressure pump is also equipped with a reliable sealing system to ensure stable operation. Based on the properties of different raw materials, you can choose different types of pumps, including piston pump, screw pump, plunger pump, and more.
- Atomization System: The nozzle is the key component of the atomization system of a pressure spray dryer. It directly decides the particle size, product shape, and drying efficiency. In general, the smaller the orifice of nozzles, the finer the spraying droplets. You can choose a suitable nozzle for your machine based on the actual requirements. The nozzle is easy to wear so it can be produced by high-strength materials to ensure a long service life.
- Drying Tower: High-quality drying towers are typically made of 316L stainless steel to ensure smooth surface thereby preventing material adhesion to the interior wall. The height and diameter of a drying tower is connected to the drying time and final capacity. It must be matched with the atomization angle, spray pattern trajectory, and hot air distributor.
- Hot Air System: The hot air system of the pressure spray dryer is used to provide a clean and stable drying medium for droplets. It offers multiple types of heat sources, such as steam, natural gas, or electric heating. The temperature of the hot air should also be controlled precisely to ensure high product quality.
- Separation System: The separation system consists of a cyclone separator and a baghouse dust collector to collect products and remove exhaust gases. As the primary separation, the cyclone separator features simple structure and consumes low energy. It can recover most of the final products. While the baghouse dust collector is used to capture extremely fine particles, achieving high recovery rates.

A pressure spray dryer mainly relies on high-pressure pump and nozzle to atomize liquids, generating uniform powders and suitable for high-viscosity materials. Its structure is more simple than the centrifugal type, making it easy to maintain. While the centrifugal spray dryer uses a high-speed rotating disc to generate centrifugal power. It is suitable to handle a large amount of flow, and is difficult to be clogged.
The machine is made of stainless steel to reduce sticking materials. Its large diameter also ensures sufficient residence time for droplets to dry, preventing the semi-dry material contact with the walls. If you have requirements, the interior walls of the drying tower can be polished or added coatings to prevent sticking issues.
The nozzle clogging issues are typically caused by the solid content deposits of raw materials. When you select the pressure spray dryer, you can purchase filter components and clog-resistant nozzles to reduce the failures. During the drying process, you should maintain continuous circulation and agitation for the liquids. And cleanliness after using is also important.
