DZ series pressure spray dryer

DZ seriesPressure spray dryer

working principle

The working process of this unit involves the high-pressure input of material liquid through a diaphragm pump, spraying mist like droplets, and then flowing down in parallel with hot air. Most of the powder particles are collected by the bottom discharge port of the tower, and the exhaust gas and its small powder are separated by a cyclone separator. The exhaust gas is discharged by a suction fan, and the powder is collected by a pollination tube located at the lower end of the cyclone separator. The fan outlet can also be equipped with a secondary dust removal device, with a recovery rate of over 96-98%.

Performance Characteristics

The drying speed is fast, and the surface area of the material liquid is greatly increased after atomization. In the hot air flow, 95% -98% of the water can be evaporated in an instant, and the drying time only needs tens of seconds to tens of seconds. It is suitable for drying heat sensitive materials.

All products are spherical particles with uniform particle size, good flowability, good solubility, high product purity, and good quality.

Widely applicable, according to the characteristics of the material, it can be dried with hot air or granulated with cold air, with strong adaptability to the material.

Simple and stable operation, convenient control, and easy implementation of automated tasks.
