The unit is a device for drying and granulating at the same time. According to the requirements of the process, the pressure, flow rate and size of the spray pump can be adjusted to obtain the required spherical particles according to a certain size.
The work process of the unit for the liquid through a high voltage input diaphragm pump, spray mist droplets, and then with hot air and fall, most of the powder from the bottom outlet collection, exhaust gas and tiny powder by the cyclone separation, waste gas discharged by the exhaust fan, a powder collecting barrel is arranged by pollination in the lower end of the cyclone separator. The exit of the fan is also equipped with two grade dust removal device, the recovery rate was above 96-98%.
The material of the tower, pipe and separator used in the contact part of the unit and the material is made by SUS304. There is enough insulating layer between the inside of the tower and the outer shell, and the filling material is superfine glass cotton. The tower body is provided with an observation door, a mirror, a light source and a control instrument, and is controlled and displayed by an electric control operating table.
The heat source unit of the unit adopts steam heating or electric heater. It has the advantages of easy operation, quick starting, compact structure, clean and clean hot air, etc.. In addition, the electric control cabinet is equipped with the control and adjustment device of the electric heater, so that the inlet temperature is stepless adjusted. For the power shortage areas, steam heating or coal burning and fuel burning hot stoves can be used to replace electric heating devices locally or in whole. The factory can provide various heating methods according to the actual needs of the users.
Fast drying, liquid surface area increased significantly after the spraying, in the hot air, can instantly evaporate 95-98% water, drying time is only several seconds to tens of seconds, particularly suitable for drying heat sensitive materials.
The products obtained are spherical particles with uniform particle size, good flowability, good solubility, high purity and good quality.
Wide range of use, according to the characteristics of materials, you can use hot air drying, you can also use cold air granulation, the adaptability of the material is strong.
The operation is simple, stable, easy to control and easy to realize automatic operation.
