Small Spray Dryer

Small Spray Dryer is a compact laboratory-scale drying system for converting liquid solutions, emulsions, and suspensions into dry powder through controlled atomization and hot-air drying. It is suitable for product development, sample preparation, formulation testing, and small-batch process research.

Water Evaporation Capacity: The dryer evaporates approximately 1.5–2 L of water per hour, depending on feed properties and operating conditions.
Small Sample Processing: The minimum feed volume is 50 mL, allowing small quantities of material to be used for laboratory trials and formulation testing.
Co-Current Air Flow: Heated air enters through the top air distributor in a spiral pattern, achieving direct contact with atomized liquid droplets for rapid moisture removal.
Powder Form: The atomization system produces fine particles with a relatively uniform distribution and free-flowing characteristics, depending on the feed formulation and drying conditions.

Two-Fluid Atomization: The liquid feed is atomized at the top of the drying chamber into fine droplets before contacting the heated drying air.
316 Stainless Steel Nozzle: The atomizer nozzle is made of 316 stainless steel for direct contact with the processed feed.
Nozzle Option: A 1.00 mm (0.04 in) nozzle is available as an optional configuration for laboratory spray drying applications.Different nozzle models can be selected according to feed characteristics and required powder particle size.

LCD Touchscreen: The LCD touchscreen displays operating parameters and allows adjustment of drying conditions during operation.
PID Temperature Control: PID control maintains the set drying temperature and supports adjustment according to the material being processed.
Real-Time Temperature Display: The operating temperature is displayed on the control interface for monitoring during the drying process.
Heated Air Circulation: The heated air enters the air distributor above the drying chamber and flows into the chamber in a spiral pattern for contact with the atomized feed.

Borosilicate Glass Drying Chamber: The drying chamber uses heat-resistant borosilicate glass, providing visual access to the drying process and resistance to thermal and chemical exposure.
Transparent Separation Components: The cyclone separator and collection components use transparent borosilicate glass, allowing powder movement and collection to be observed during operation.
316 Stainless Steel Contact Component: The spray nozzle is manufactured from 316 stainless steel for contact with the feed material.
Compact Laboratory Structure: The 2 L/h system integrates feeding, heating, atomization, drying, separation, and collection into one laboratory-scale unit.

Cyclone Separation Mechanics: Separates dry powder from exhaust air via centrifugal force routed to the bottom collection vessel.

Sample Retrieval Protocol: The feed peristaltic pump must be temporarily turned off during powder harvesting and restarted seamlessly to resume the drying cycle.

Sealed Collection Vessels: Glass collection bottles connect securely to the system base to prevent powder loss or fine particle leakage.

Pre-Sales Configuration: Technical information can be provided for model selection, feed capacity, nozzle configuration, and equipment requirements before ordering.
Factory Testing: Each spray dryer undergoes assembly inspection and functional testing before shipment, including checks of the assembled equipment and operating functions.
Spare Parts Support: Replacement parts can be supplied for components such as spray nozzles and other equipment assemblies according to the machine configuration.
Technical Assistance: Post-sale support covers equipment operation, troubleshooting, and technical guidance for customers using the spray dryer.
