USED BUCHI B-290

Manufacturer Information
BUCHI
BUCHI manufactures laboratory-scale process equipment used in research, development, formulation, and small-scale production environments. The B-290 Mini Spray Dryer is designed for laboratory spray drying applications, while the accompanying B-295 Inert Loop supports appropriately configured spray drying processes involving compatible organic solvents under a controlled inert-gas atmosphere.
Description
Available for sale is a used 2018 BUCHI Mini Spray Dryer, Model B-290, equipped with a glass drying chamber and atomizer and accompanied by a BUCHI B-295 Inert Loop.
The B-290 is designed to convert compatible liquid feeds, solutions, suspensions, or emulsions into dry powders through atomization and controlled drying. Its laboratory-scale configuration makes it useful for research and development, formulation work, feasibility studies, product development, and small-batch powder processing.
The included B-295 Inert Loop expands the system's potential capabilities for compatible organic-solvent applications under an inert gas atmosphere. The supplied configuration includes oxygen and pressure control intended to support safer inert-loop operation and reduce explosive-atmosphere risks.
The B-295 has a stated cooling capacity of 800 W at -10°C and a minimum outlet temperature of -20°C.
Because solvent service can involve flammable or hazardous materials, buyers should verify the complete system configuration, installed safety devices, gas requirements, solvent compatibility, operating limits, ventilation, electrical classification, and current manufacturer procedures before use.
