Pressure Spray Dryer

Pressure spray drying equipment is a kind of equipment which can accomplish drying and granulation simultaneously.According to the technological requirements, the pressure, flow rate and the size of the jet hole of the feed liquid pump can be adjusted to obtain the necessary spherical particles in a certain size proportion.

pressure spray dryer

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 pressure spray drying equipment has a fast drying speed, and the surface area of the material liquid is greatly increased after atomization. In the hot air flow, 95-98% water can be evaporated instantly, and the drying time is only 10 to dozens of seconds, especially for the drying of heat-sensitive materials. The products are spherical particles with uniform particle size, good fluidity, good solubility, high purity and good quality. Wide range of use, according to the characteristics of materials, can be used to dry hot air or cold air granulation, strong adaptability to materials. Simple and stable operation, convenient control, easy to achieve automation.

Pressure spray drying equipment can be used for:

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

Food: amino acid and similar, seasoning, protein, starch, dairy products, coffee extract, fish meal, meat essence, etc.

Pharmacy: Chinese patent medicine, pesticide, antibiotic, medicine powder, etc.

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

Spray granulation: various fertilizers, alumina, ceramic powder, pharmaceutical, heavy metal super hard steel, fertilizer, granular washing powder, Chinese patent medicine, etc.

Spray cooling granulation: amine fatty acid, paraffin, glyceride, tallow, etc.

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

1.Product moisture content is too high
Exhaust air temperature is the main factor affecting the moisture content of finished products, so the reason for the high moisture content of products is generally the exhaust air temperature is too low. And the exhaust air temperature can be adjusted by the amount of feed. Therefore, the corresponding measures are appropriate to reduce the amount of feed, in order to improve the exhaust temperat...more
