The Büchi Nano Spray Dryer B-90, for particle generation in the nanometre range, uses minimal sample quantities and claims to achieve the highest possible product recovery rates.
The dryer is designed to evaluate drying during early stages of product development in the pharmaceutical, food, advanced materials and nanotechnology industries for aqueous- or solvent-based formulations.
The droplet generation is based on a piezoelectric-driven actuator which vibrates a thin, perforated membrane in a small spray cap.
The membrane features an array of micron-sized holes. The actuator is driven at ultrasonic frequency, causing the membrane to vibrate, creating precisely sized droplets with narrow droplet distribution.
The heater technology is based on porous metal foam, providing a laminar gas flow in the drying chamber.
Optimal energy input allows fast heating times, up to 120°C, for gentle drying of heat-sensitive materials.
The dried particles are separated by an electrostatic particle collector with good recovery rates. It enables easy collection of small sample quantities of high-value products.
