Product Introduction
Pressure spray drying is a widely used process in the liquid processing and drying industries, particularly for producing powdered or granular products from low-viscosity liquid feedstocks via spray drying. Spray granulation typically employs pressure atomization. Our plant has established design and manufacturing capabilities for large-scale pressure spray dryers with a diameter of 8 meters, a height of 45 meters, and a liquid feed rate of 4 tons per hour. We tailor equipment configurations to suit the specific characteristics of different materials.
Working Principle
After being conveyed by a high-pressure pump and reaching a very high pressure, the liquid enters the rotating chamber of the nozzle through the tangential inlet of the pressure nozzle. Within the rotating chamber, the liquid acquires rotational motion, converting its static pressure energy into kinetic energy before being ejected from the nozzle to form fine droplets. Meanwhile, hot air is distributed uniformly downward from the top of the tower via a hot-air distribution device, flowing parallel to the droplets and ensuring thorough contact, thereby completing the drying and particle formation processes.
Product Features
- It dries very quickly, making it particularly suitable for heat-sensitive materials.
- The product is in the form of spherical granules, with uniform particle size, excellent flowability, good solubility, high purity, and superior quality.
- It can be equipped with fine-powder recirculation to meet users’ particle-size requirements.
- The particle size, bulk density, and moisture content of the product can be adjusted within a certain range; it has a wide range of applications and, depending on the material properties, can be used for hot-air drying as well as cold-air granulation, demonstrating strong adaptability to various materials.
