Pressure spray granulation dryer

Pressure spray granulation dryer


YPL series pressure spray granulation dryer is a kind of device that can accomplish drying and granulation simultaneously. According to the requirements of the process can be adjusted to the liquid pump pressure, flow, the size of the jet hole, the required size according to a certain proportion of spherical particles.

The unit working process for the material liquid through the diaphragm pump and high pressure input, spewing fog droplets, and then with hot air and flow down, most of the powder of bottom discharging mouth collection, waste gas and its tiny powder through cyclone separation, through the exhaust fan, exhaust powder by the pollination of the bottom of cyclone separator tube collection, fan outlet can also be equipped with secondary dust removal device, the recovery in 96 - more than 98%.

The tower body, pipelines and separator of the unit in contact with materials are made of SUS304. There is enough moisture layer between the inside of the tower body and the outer shell. The filling material is ultra-fine glass wool. The tower body is equipped with observation door, viewing mirror, light source and control instrument, which are controlled and displayed by the electric control operating table.

The heat source unit adopts steam heating or electric heater, which has the advantages of easy operation, quick start, compact structure and clean hot air. In addition in the electrical control cabinet equipped with electric heater control adjustment device, so that the import temperature stepless regulation, for the lack of electricity areas can use steam heating or coal hot air furnace and other ways, local or all instead of electric heating device, the factory can provide the need for heating according to the actual users.

Applicable Scope:

Spray drying granule:

Chemical industry: catalyst, resin, synthetic washing powder, grease, ammonium sulfide, dyes, dye intermediates, white carbon black, graphite, ammonium phosphate, etc.

Food: amino acids and analogues, seasonings, protein, starch, dairy products, coffee extracts, fish powder, meat essence, etc.

Pharmaceutical: Proprietary Chinese medicines, pesticides, antibiotics, pharmaceutical granule, etc.

Ceramics: magnesium oxide, porcelain clay, various metal oxides, dolomite, etc.

Spray granulation: all kinds of fertilizer, alumina, ceramic powder, pharmaceutical, heavy metal super hard steel, chemical fertilizer, granular washing powder, Chinese patent medicine.

Spray cooling granulation: amine fatty acids, paraffin wax, glycerate, tallow, etc.

Spray crystallization, spray concentration, spray reaction and other aspects are often used.


The drying speed is fast, and the surface area of the material solution is greatly increased after atomization. In the hot air flow, 95-98% of the water can be instantly evaporated. The drying time is only ten seconds to ten seconds, especially suitable for drying heat-sensitive materials. All products are spherical particles, uniform particle size, good fluidity, good solubility, high purity, good quality.

Wide range of use, according to the characteristics of the material, you can use hot air drying, also can use cold air granulation, the adaptability of the material. Simple and stable operation, convenient control, easy to achieve automatic operation.
