Spray Dryer Application:
Spray Dryer operates with two-fluid atomization, offering broad applicability to various solutions, including emulsions and suspensions. With a minimum sample volume of 30 mL and completes the drying process in approximately 1.0 to 1.5 seconds, particularly suitable for heat-sensitive materials such as biological products, biopesticides, and enzyme preparations. Widely used for the preparation of micro-particles and powders in universities, research institutes, food, pharmaceutical, and chemical industries.
Spray Dryer Feature:
9" color touchscreen for real-time display, supports historical data and trend curve queries, ensuring process traceability.
Closed-loop inert gas (nitrogen) serves as the drying medium, with controllable oxygen concentration, allowing the material to be dried in an inert environment.
O2 concentration sensor range of 0–100%, N2 flow measurement range of 16–160 L/min, with protection triggered when O2 concentration exceeds 3%.
Automatic overpressure relief (above 0.05 MPa) ensures the safety of operators and equipment.
Solvent recovery unit features an integrated design, compact structure, and simple maintenance.
Spiral stainless steel condenser tube, cooled by circulating low-temperature silicone oil, ensuring high solvent recovery rates.
Built-in heat exchanger reduces energy consumption during the drying and recovery processes.
Enclosed filter cartridges remove dust, reducing dust emissions and sample loss
Modular design allows for switching between high-temperature spray drying and organic solvent drying modes.
Full stainless steel construction, with quick-connect fittings on the drying system for convenient disassembly and cleaning.
Two-fluid atomization system with built-in oil-free air compressor, preventing oil mist contamination.
Built-in nozzle cleaner (cleaning needle) with automatic clearance upon clogging, adjustable cleaning frequency.
Drying temperature control utilizes PID technology, ensuring accurate temperature regulation with a heating control precision of ±1°C.
Peristaltic pump regulates the feed rate, with a minimum sample volume of 30 mL to minimize sample loss.
More than 95% of the dry powder falls within the same particle size range, ensuring consistent powder quality.
Real-time monitoring of oxygen concentration, pipeline pressure, condensation temperature, filter differential pressure during operation.
