YPG Pressure spray dryer

1. General description of Pressure spray dryer

Pressure spray dryer is an equipment that can dry and granulate at the same time. According to the process requirements, the pressure, flow of feeding pump and orifice size of spray nozzle can be adjusted to obtain the required spherical particles with a certain proportion of size.

The working process of the equipment is as follows: The liquid material is input to the spray nozzle by the high pressure diaphragm pump, and sprayed as mist droplets, and then flows down in parallel with the hot air. The moisture in the droplet is evaporated instantly, and the solid forms powder particles. Most of the powder particles are collected from the discharge port at the bottom of the tower. The waste gas and small powder are separated by the cyclone separator, then the waste gas is discharged by the exhaust fan, and he powder is collected by the barrel under the rotary air separator. The outlet of the fan can also be equipped with a secondary dust removal device, The recovery rate can reach more than 99%.

2. Features of Pressure spray dryer

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

2. The product is spherical particles with uniform particle size, good fluidity, good solubility, high purity and good quality.

3. Wide application range. According to the characteristics of materials, it can be used for hot air drying or cold air granulation. It has strong adaptability to materials.

4. Simple and stable operation, convenient control and easy to realize automatic operation.

3. Application of Pressure spray dryer

Chemical industry: Organic catalyst, resin, synthetic washing powder, grease, thiamine, dye, dye intermediate, white carbon black, graphite, ammonium phosphate, etc.

Food: Amino acids and analogues, condiments, protein, starch, dairy products, coffee extract, fish meal, meat essence, etc.

Pharmaceutical: Chinese patent medicine, pesticide, antibiotic, 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, granular laundry powder, etc.
