spray dryer

spray research, inc. has two laboratory-scale spray dryers which find frequent application in process development work. Both dryers employ borosilicate glass drying chambers and cyclone separators allowing optical access to the entire drying path. The systems operate under a slight negative pressure which enhances drying. The spray dryers are used for studies involving spray drying, micronization, micro-encapsulation, and recovery for synthetic and extracted products.

The Yamato Pulvis GA-31 spray dryer has a slightly larger standard spray chamber [I.D.= 140mm] and can achieve higher drying air inlet temperatures. This dryer can also accommodate custom-fabricated spray chambers up to a maximum outside diameter of 300mm. The basic unit can be easily reconfigured as a fluidized-bed dryer and granulator.

The Buchi B-190 delivers tighter control of inlet air temperature and a lower maximum inlet temperature, which makes this unit well-suited to work involving heat-liable products. A secondary filter downstream of the cyclone separator extends the dryer's capabilities to more finely atomized sprays and valuable product.

The spray dryers are also used extensively for developing the acceptance criteria and tolerances employed during spray dryer atomizer qualification.
