YPG Series Pressure Spray Dryer (Co-Current)

The YPG Series pressure spray dryer uses a pressure nozzle at the top of the tower to atomize the feed into a co-current hot-air stream. Feed pressure, nozzle selection, feed rate, and drying conditions are coordinated to develop the required powder or granule characteristics.

Suitable for: pumpable solutions, emulsions, suspensions and slurries suitable for pressure atomization.

Product Overview

The YPG Series Pressure Spray Dryer (Co-Current) uses a pressure nozzle mounted at the top of the drying tower to atomize liquid feed into fine droplets. Hot air enters from the tower top and moves downward in parallel with the droplets, forming a co-current drying flow.

The pressure spray dryer equipment is designed for high powder recovery, minimal wall deposition and energy-efficient drying. It is particularly suitable for heat-sensitive materials and is widely used for food products, dyes and chemical intermediates.

Working Principle

Liquid feed is pressurized and delivered to the pressure spray dryer nozzle installed at the top of the drying tower, where it is atomized into fine droplets. Hot air enters from the tower top and flows downward in the same direction as the droplets.

Moisture evaporates during this co-current contact, and the dried product is discharged from the bottom of the tower. Fine powder entrained in the exhaust air is separated by the cyclone and dust collector.
