Spray Drying - Industrial Production

Ceramic Industry

Spray drying is applicable to tile and electronic press powders, and plays an important role in the industrial development of high performance (advanced) ceramics. The ability to meet particle size distribution requirements, produce a spherical particle form, and handle abrasive feedstocks is an important reason for the widespread use of spray dryers in the ceramic industries.

Chemical Industry

Spray dryers for the chemical industries produce a variety of powdered, granulated and agglomerated products in systems that minimize formation of gaseous, particulate and liquid effluents.

High efficiency scrubber systems and high performance bag filters prevent powder emission, while recycle systems eliminate problems of handling solvents, product toxicity, and fire explosion risks. Special component designs (e.g. atomizers) are available for abrasive and corrosive feedstocks. High thermal efficiencies, low maintenance costs, full environmental protection, computerized control, dust-free working area are some of the features of today's spray dryers.

Food Industry

Food products in powder or agglomerate form:

Spray drying is ideal for these heat sensitive products, where selection of system and operation is the key to high nutritive and quality powders of precise specification.

Pharmaceutical Industry

Pharmaceuticals in powder or agglomerate form:

Spray dryers designed specially for integration into batch or continuous operations under sanitary or aseptic conditions. Systems also available for taste masking and encapsulation. Dryers with integrated fluid beds are ideal for producing non-dusty powders for perfect tabletting.

Polymer Industry

Polymer dispersions and solutions in water or organic solvents are spray dried under closely controlled operating conditions, producing powders to precise particle size, heat treatment, and redispersibility specifications. Low softening point products are produced continuously in plants with air-brooms, air-sweeps or integrated fluid beds. For drying moist polymer powders, NIRO offers fluid beds.
