Working Principle of Niro Spray Dryer
The essence of FANQUN Niro spray dryer lies in its ability to transform complex drying processes into stable, repeatable, and industrial production through uniform atomization, precise airflow control, and flexible modular design. This reliably converts your liquid formulations into high-quality powder products with market competitiveness, while maximizing the preservation of the activity of heat-sensitive components.
The workflow in operation is as follows:
Step 1: Precision atomization
Atomization of liquid material into billions of uniform droplets is the most crucial step in determining the final powder particle size.The liquid material is delivered to the center of a high-speed rotating atomizer, where it is shaped into uniformly sized fine droplets by the immense centrifugal force of the high-speed rotating disc (speeds up to 15,000-20,000 rpm).
Step2: Instant drying
Filtered and heated clean hot air enters the top of the spray dryer tower in a stable and uniform spiral or laminar flow state through a unique air distributor. The atomized material droplets mix instantly with the hot air at the top of the tower. FANQUN Niro spray dryer’s design where the hot air moves in the same direction as the droplets, ensures that the wettest droplets contact with the hottest air. Subsequently, the particle temperature drops rapidly due to moisture evaporation, which perfectly protects heat-sensitive ingredients of material.
Step3: Gas powder separation for efficient collection of powder
The airflow carrying the dried powder enters the cyclone separator from the bottom of the spray dryer tower, where centrifugal force separates most (>95%) of the coarser particles.The exhaust gas containing fine powder enters a bag filter for final, highly efficient collection, achieving a collection efficiency of over 99.9%, ensuring product yield and compliance with environmental emission standards.

Suitable for small batch experiments, the evaporated amount of moisture is within 5 kg/h-25 kg/h, the temperature can precise control.

Key Components of a FANQUN Niro Spray Dryer
Liquid material feed system
A stable and continuous feed system contains raw material type with agitation and high pressure feed pump. It stably and controllably delivers the liquid (solution, suspension, emulsion) to the atomizer. Liquid material feed system ensures uniform droplet formation and stable consistent powder quality.
Atomization system
This system is configured with centrifugal atomizer(rotary atomizer) and high pressure nozzle atomizer. The centrifugal high speed rotary atomizer breaks the liquid into uniform and fine droplets, greatly increasing its surface area for instant drying. FANQUN Niro spray dryer’s atomization system is good at droplet size controlling and it is adaptable to different viscosities and solid contents. Precise atomization directly determines particle size distribution, bulk density and solubility of the final powder.
Niro spray dryer chamber
Niro spray dryer chamber is a large vertical cylindrical cone-shaped structure chamber. It provides sufficient residence time for the droplets to dry completely.The FANQUN Niro spray dryer chamber’s cone angle design,smooth inner wall, thermal insulation performance and observation cleaning ports are all designed to optimize powder flow, prevent adhesion and facilitate cleaning.
Air Heater&Distribution System
The air heater system includes steam heater, direct gas heater, electric heater, or thermal oil heater. It heats the intake clean air to the precise process temperature (typically 150°C – 300°C, depending on the material). The hot air system precisely controls inlet air temperature. It ensures efficient drying and prevent overheating or product degradation.
Advantages of Niro Spray Dryer
Compared with the traditonal spray dryer, the Niro type spray dryer has the following advantages:
Niro Spray Dryer for Heat Sensitive Materials
Once the material is heated for too long, its structure will be damaged. The material will deteriorate and the product will be completely useless. The hot air from Niro spray dryer comes into instant contact with the droplets, which shortens the residence time of the material. The moisture in the material will evaporate in an instant. This ensures that the material will not deteriorate.
Cost Savings
The machine can operate continuously for 24 hours without interruption, with a high mechanical utilization rate. This reduces the losses caused by idle machines. Machine operation is simple. It usually need only 1-2 people to start and stop.The Niro spray dryer can record operating data, and perform normal inspections. This also saves labor costs.
