What is use of high pressure nozzle in spray dryer?
The function of a spray nozzle in a spray dry system is to control the feed stock flow rate and uniformly distribute atomized droplets/particles into the heated drying chamber. Spray dry nozzles typically operate at higher pressures or utilize air-atomizing techniques to produce droplets in the 30 - 120 micron range.
Working principle
YPG Pressure Spray Dryer is an apparatus that can finish drying and granulating at the same time. The needed ball granule with certain size and ratio can be gotten in accordance with requirements of process to adjust pressure, flow, and size of atomizing hole.The working of this set is as follows: the liquid of raw material is pumped in through diaphragm pump. The liquid of raw material be atomized into tiny droplets. Then it gathers with hot air and falls off. Most parts of powder material will be collected through the outlet of discharged at the bottom. The wasted air and fine powder will be collected through collector at the bottom of cyclone. At the outlet it can also be equipped with two grades of duster. Its ratio of recovery can be above 99%.
Features:
1. The dry speed is fast and suitable for drying thermal sensitivity material particularly.
2. The finished product is ball granule with uniform size. Its fluidity and solubility are good. The purity of product is high and its quality is good.
3. It applied scope is wide. According to the characteristics of raw material, it can use hot air to dry and can also use cool air to granulate. It has strong adaptability to raw materials.
4. Its operation is simple and stable and its control is simple and convenient and is easy to realize automatic operation.
