·Kuye et al A review of spray dryer design 37 THEORY OF SPRAY DRYING PROCESS A spray drying system may consist of the following unit operations • Pre concentration of liquid feed • Atomization creation of droplets • Drying of the droplets in stream of hot dry air • Separation of powder from moist air • Cooling
·Using the experimental data from small scale to design the large scale unit Physical Rate Rearrange the correlation in a function of dimensionless group Reaction rate Using reaction rate expression / rate law Spray dryer model and atomizer types in Laboratory scale a Buchi 290 b Two fluid nozzle
3 ·Design of Spray Dryer Machine Vera Sameh Hana Samir and Ahmed Badawy Vera Sameh October University for Modern Sciences and Arts MSA Giza Egypt Spray drying aims to reduce the water content of a material so that the product is made into powder by liquid evaporation Spray drying produces droplets of liquid through liquid atomization
·Free Excel calculation tool Spray Dryer Heat and Mass Balance HMB You can access it is not intended for detail design It is not a commercial product no guarantee is given on the results Please consult a reputable designer for all detail design you may need Source Spray Drying K Masters Leonard Hill Books 1972 pages 54 64
· Spray dryers 21 Figure 9 Schematic of a closed cycle spray drying system A large interfacial area is produced and consequently a high rate of evaporation is obtained Examples are dried milk powder and urea pellets The ow of gas an liquid may be counter or co current or a com bination Salim Ahmed PROC 5071 Process Equipment Design I
Download CAD block in XLS Spray drying heat & mass balance program for drying based engineering useful for engineers;students & manufacturer KB
·For spray drying of liquids one may need evaporators to concentrate the liquid to a certain degree before it is sent to a spray dryer Simulation of the drying operation as a system or the whole drying plant can lead to optimized design and operation 2 Dryer design calculations which include basic heat and mass balance
·characteristics of the final product This handbook reviews many types of dryers and provides guidelines for their selection Certain types of commonly used dryers are reviewed in detail Since drying is an energy intensive operation this handbook also provides information on techniques to improve efficiency APV Dryer Handbook 12/6/00 10 52
The major parameters in the design of spray dryers are discussed A Lagrangian approach combining experimental data with theoretical concepts is proposed to develop design methods Vortex flow
