Product Description
Most laboratory spray dryers make fine powder. Making coarse powder in a laboratory is the harder problem — particles of 40 to 100 μm need a larger chamber, a bigger nozzle and more air than a bench unit can provide, which is why that size range normally means renting time on a pilot plant. The DL-410 produces it on a laboratory floor.
It evaporates up to 3000 mL/h — more than twice the ADL-311S — with an inlet range reaching 300 °C and a feed pump running to 70 mL/min. The nozzle carries a needle that clears the mesh automatically rather than on an operator's pulse, which is what makes a multi-hour unattended run realistic. Small, expensive or heat-sensitive samples still dry quickly, because the residence time is set by droplet size, not by batch size.
Key Features
- Maximum evaporation 3000 mL/h — roughly 2.3× the ADL-311S
- Particle size 40 to 100 μm — the range most laboratory dryers cannot reach
- 40 to 300 °C inlet, ±1 °C
- Downward spray parallel-flow contact system
- Two-way nozzle ø0.7 mm, No. 3 standard; nozzles 4 and 5 optional
- Automatic spray-line cleaning — a needle inside the nozzle clears the mesh without operator intervention
- Feed pump to 70 mL/min, quantitative peristaltic
- Dry air to 1.0 m³/min, spray air to 600 kPa
- 2 kW × 2 stainless pipe heaters at 240 V
- Self-diagnostic safety with sample feed reversal
- Factory-installable inlet/outlet temperature recorder (part 212792)

What's Included
- DL-410 spray dryer
- Sample liquid tube — silicone, 2 pcs.
- Safety cover
- Static removal brush
- Air hose
- Exhaust duct
- Instruction manual
Not included: Air compressor, GAS-410 organic solvent recovery unit, GWS-410 solvent washing unit, inlet/outlet temperature recorder (212792, factory installed), Viton/Tiron feeding tube, and optional nozzles 4 and 5.
Installation Requirements
- Electrical: single phase AC 220 V, 50/60 Hz, 24 A — a dedicated circuit, connected by an electrician.
- Compressed air: 28 L/min at 8 kgf/cm² is required and is not supplied.
- Floor space: 1060 × 880 mm footprint, 1750 mm tall and 180 kg. Check the door and ceiling height on the delivery path, not just the bench.
- Organic solvents: require the GAS-410 recovery unit, and with GAS-410 you also need N₂ at 99.99 % (medical grade).
- Exhaust: duct the exhaust out or to a hood.
