Description

Particle formation for lab scale

BUCHI’s proven, reliable and versatile solutions for Spray Drying cover a broad range of applications. Discover the time- and cost-saving solutions for R&D particle formation.

Your advantages
∙ Continuous process
∙ Short process time (up to 1 L/h)
∙ Low cost at industrial scale∙
∙ Protection of core material
∙ Mild drying conditions
∙ Scale-up your process to high product volumes
∙ High yields obtained (< 90%)
∙ Controllable particle size and morphology (0.3 – 60 µm)
∙ Shortest process times and fast cleaning
∙ Work with low flow rates and small sample volumes
∙ Process control due to glass assembly
∙ With the Mini Spray Dryer B-290 or with the Nano Spray Dryer B-90 with the Inert Loop B-295 it is possible to spray with organic solvents without risk of explosion, because the system works under inert conditions.

Solution «Spray Drying Small» (300 nm – 5 µm). Laboratory Spray Drying for small samples and particles. You deal with expensive sample materials or want to obtain the smallest particles.

What is the functional principle of the laboratory spray dryer ?
Step 1 Heating: Heat the inlet air to the desired temperature (max. 220 °C)
Step 2 Droplet formation: Two-fluid nozzle for the B-290 and ultrasonic spray head for the B-90
Step 3 Drying chamber: Conductive heat exchange between drying gas and sample droplets
Step 4 Particle collection: Cyclone technology for the B-290 and electrostatic particle collector for the B-90
Step 5 Outlet filter: Collection of finest particles to protect the user and the environment
Step 6 Drying gas: Delivered by aspirator for the B-290 and by aspirator or compressed air for the B-90
Step 7 Filtering of the drying gas
