Industrial Spray Drying Machine

Industrial Spray Drying Machine is designed to convert pumpable liquid feeds into free-flowing powder through controlled atomization and rapid moisture removal. It suits process-scale drying where consistent powder handling is required.

Food & Ingredients: Suitable for selected liquid food ingredients, extracts, flavoring materials and other pumpable formulations requiring conversion to powder.

Pharmaceutical & Nutraceutical: Applicable to suitable aqueous formulations and extracts where controlled drying conditions are compatible with the material.

Chemical Materials: Can be used for selected solutions, suspensions and emulsions requiring rapid moisture removal and powder formation.

Ceramic & Functional Materials: Suitable for certain ceramic slurries and inorganic suspensions when the feed can be continuously pumped and atomized.

High-Speed Atomization: The adjustable atomizer operates at up to 30,000 r/min to disperse the liquid feed into fine droplets before drying.

1.00 mm Nozzle: The specified nozzle diameter provides a defined flow passage for the feed and should be matched with feed viscosity and required throughput.

Variable Operating Conditions: Atomization speed and feed rate can be adjusted together rather than relying on a fixed setting for different materials.

Process Matching: Atomization parameters should be established from the feed properties and target powder characteristics during process testing.

Feed System: A peristaltic pump provides controlled liquid feeding and allows adjustment of feed rate during operation.

Heating & Air Supply: The hot-air system supplies controlled drying air, with inlet temperature adjustable up to 300°C.

Drying Chamber: Provides the controlled space for contact between atomized droplets and heated air during rapid moisture evaporation.

Control System: Digital controls allow operators to monitor and adjust key operating conditions such as temperature, feed rate and atomization speed.

Collection Components: Powder separation and collection equipment can be configured according to powder properties and required recovery performance.

Liquid Feeding: The feed is delivered continuously to the atomization system through the peristaltic pump.

Atomization: The liquid is dispersed into fine droplets to increase the surface area available for moisture evaporation.

Hot-Air Drying: Atomized droplets contact controlled hot air, allowing moisture to evaporate within a short drying period.

Powder Formation: As moisture is removed, the droplets develop into dry particles with characteristics influenced by feed composition and operating conditions.

Particle Separation: The drying system separates dried powder from the process air before discharge.

Powder Collection: Collected powder is directed to the designated receiving section for subsequent handling or packaging.

Fine Powder Handling: Additional separation components can be considered when the feed produces a high proportion of fine particles.

Recovery Evaluation: Powder recovery should be assessed using the actual feed material because particle size, density and stickiness affect collection efficiency.

Feed Material Evaluation: Test conditions can be established from the customer's actual feed composition, solids content, viscosity and thermal characteristics.
Parameter Testing: Feed rate, inlet temperature and atomization speed can be varied to identify suitable operating conditions.
Powder Assessment: Test results can be evaluated for moisture content, particle characteristics, appearance and recovery according to the customer's requirements.
Production Trial: Where applicable, customer material can be used for trial drying to verify process compatibility before final equipment configuration.

Pre-Installation: Equipment dimensions, power requirements, ventilation, installation conditions and utility requirements are confirmed before delivery.

Commissioning: Key operating parameters are checked and adjusted during initial system operation.

Operator Guidance: Operating procedures, parameter adjustment and routine equipment handling can be explained during commissioning.

Technical Support: Remote technical assistance and spare-parts support are available for operating issues and routine maintenance after delivery.
