YPG Pressure Spray Dryer

Induce hot air from the top of drying tower, at the same time, pump the material liquid to the top of the tower by high pressure pump, the feeding solution becomes into fine beads or small droplets through the spray nozzles. When the droplets meet the high temperature hot air, the water will be evaporated immediately, and the material liquid is dried into dry product in a very short time, the product is discharged from the bottom of the drying tower, or from the cyclone (depend on the configuration). When the hot air contacts with the droplets, the temperature declines significantly, and the humidity increases greatly, and then will be exhausted by exhaust fan. The fine powder in the air will be collected through different separating devices

There’re different fine powder separation and recovery devices, such as cyclone (the common type and various combination type), bag filter, cyclone + bag filter, cyclone + wet scrubber, and bag filter + wet scrubber etc. We should different fine powder separation and recovery devices as per the characteristics of product and requirements of customer.

Depend on the product features and requirements, we might install secondary drying and cooling system (such as ZLG vibration fluid bed or pneumatic transportation), formulation system or powder sieving system etc after the spray dryer, or dehumidifier.

Fast Drying Speed. Atomization significantly increases the surface area of the liquid material.

95%-98% of moisture evaporates instantly in the hot air stream, completing drying within seconds. Especially suitable for heat-sensitive materials.

Superior Product Quality. Excellent uniformity, fluidity, and solubility. High-purity output with consistent quality.

Simplified Production Process. Easy operation and control.

Adjust nozzle pressure, feed rate, and aperture size to produce uniform spherical granules with precise size distribution—tailored to your process needs.
