Industrial Dryers
Drying equipment selected for the material, moisture-removal duty and required final product. ATTOMO provides engineering and equipment scope for specified spray and rotary drying applications.
Process and equipment approach
Spray drying atomises a liquid feed into droplets that contact a drying gas. Rotary drying handles a different feed and contact arrangement; direct and indirect heating are distinct choices. Particle size, temperature sensitivity, solvent vapours and dust characteristics affect equipment selection and process safeguards.
Applications and product requirements
Industrial drying removes moisture or another volatile component to obtain a specified solid product. Feed form matters: a pumpable solution, slurry, filter cake and granular solid do not behave alike. The enquiry should define the final moisture, particle condition, temperature limit and downstream handling requirement.
Equipment and operating approach
Spray drying converts an atomised liquid into dried particles in a drying-gas stream. Rotary arrangements can use different contact and heat-transfer methods for suitable solids. Vacuum drying is a separate option for duties that need reduced pressure. Selection must consider stickiness, thermal degradation, residence time and product collection; no dryer type is suitable for all materials.

- Instrumentation and controls as specified
Materials and configuration
The supply boundary may cover feed equipment, the drying chamber or vessel, heating surfaces or hot-gas interface, separators, fans, condensers where applicable, and product discharge. Contact materials, internal finish, seals and cleanability depend on the product and cleaning method. Solvent recovery, exhaust treatment, dust collection and explosion protection must be expressly allocated.
Utilities and operation
Quote the moisture-removal duty as well as feed tonnage. Heating medium, electrical power, exhaust conditions, cooling and vacuum needs depend on the selected process. Combustible dust or flammable solvent requires a documented hazard assessment and protective design. Trial drying may be required to establish product behaviour before moisture, throughput or energy performance is committed.

Frequently asked questions
When is spray drying appropriate?
It is considered for pumpable liquid feeds that can be atomised and dried to the required powder. Viscosity, solids, stickiness and temperature sensitivity determine feasibility.
Is drying capacity the same as feed capacity?
No. A dryer rated by water evaporation cannot be selected from wet-feed tonnage alone. State inlet and outlet moisture on a clear basis and the required dry-solids throughput.
Can solvent-bearing material use a standard hot-air dryer?
This cannot be assumed. Solvent properties and vapour concentration determine the required containment, recovery, inerting or other protective measures and equipment arrangement.
How are moisture and product quality verified?
Agree sampling locations, test methods, stable operating conditions and limits for moisture, particle properties and thermal damage before an acceptance trial.
