YPG series pressure spray (cooling) dryer

YPG series pressure spray (cooling) dryer adopts a pressure atomizer to atomize the solution or slurry material into fine droplets by the pressure of the diaphragm pump, so that the surface area is significantly increased. It can be quickly exchanged with hot air so as to obtain powder or fine particle products.

YPG series pressure spray (cooling) dryer


Pressure spray dryer is a device that can complete drying and granulation at the same time. According to process requirements, the pressure, flow rate and size of nozzle holes can be adjusted. Obtain the required spherical particles of a certain size ratio.

The working process of the pressure spray dryer is: the material liquid is input through the diaphragm pump at high pressure, spraying mist-like droplets, and then flows down with the hot air. Most of the powder particles are collected by the discharge port at the bottom of the tower. The waste gas and its fine powder are separated by a cyclone separator. The exhaust gas is discharged by the exhaust fan. The powder is collected by the powder collecting tube under the cyclone separator. The outlet of the fan can also be equipped with a secondary dust removal device. The recovery rate is 96%-98%.

The materials of the tower body, pipes and separators in the contact part of this unit with the materials are all made of SUS304. There is an insulation layer between the inside of the tower body and the outer shell, and the filling material is rock wool. The tower body is equipped with an observation door, a sight glass, a light source and a control instrument, which are controlled and displayed by an electrical control console.

The heat source of this unit adopts steam heater, electric heater or other types, which has the advantages of convenient operation, fast start-up, compact structure, clean hot air and so on. In addition, a heat source control and adjustment device is installed in the electrical control cabinet, so that the temperature of the inlet can be adjusted steplessly. Our factory can provide different heating methods according to the actual needs of users.
