Bench-top Small Spray Dryer

On-table model

The instrument can be placed on the experiment table, or Labfreez inert loop system SD-501, featuring small size and convenient operation;

For aqueous solution and organic solvent
SD-500 laboratory spray dryer has the basic type and the organic solvent type SD-501 (with inert loop system). SD-500 laboratory spray dryer is for aqueous solution, which can simply be updated to organic solvent type after equipped with SD-501 inert loop system;

Homocentric spray atomizer
During experiments, the new spray atomizer would never be off-center in atomization, and there won’t be affected recovery rate by spraying on the bottle wall. The spray atomizer can change the spray site to improve the spray effect by moving up and down; notably, the spray atomizer has excellent adaptability to material with high viscosity and few blocking situation;

The exhaust air is discharged after recovery in the bag filter
SD-500 laboratory spray dryer standard tail gas dedusting equipment can reduce environmental pollution while effectively improving the yield, especially the yield of difficult recycle;

Controls & Functionality
SD-500 laboratory spray dryer is designed to ensure that all functions are simple to select and adjust, to quickly achieve the optimum conditions for spray drying. The operator can control the following functions:

Inlet Temperature
Gasflow Volume
Pump Speed
De-blocker Frequency

Easy to use 
PLC automatic control, One-click boot.
Color Touch Screen, Fast setup and cleaning times
Scale up to pilot or industrial scale possible.
Visible process due to glass assembly
Adjustable particle size (1 – 25 microns)

Two Fluid Nozzle with SUS316L stainless steel 

The stainless steel spray assembly consists of an inner tube for the liquid sample leading to a small diameter jet. An outer tube directs compressed air to the nozzle. All units are supplied with 0.7mm jets, other sizes are available as accessories. The spray assembly incorporates an automatic de-blocking device that prevents the jet nozzle from becoming blocked, the de-blocking needle is activated by an integral compressor. De-blocking is sometimes necessary with materials which may solidify or when large particles in suspension cause blockages in the jet.

Trusted by the users Over 1,500 customers of top universities, enterprises and research institutes use our mini spray dryer. And exported to more than 40 countries & regions such as the United States, Italy, South Korea, Mexico, Singapore, Canada, Malaysia, Chile and Russia.
