Objective: To optimize molding process of Ganershu pellet. Method: With yield of pellets

roundness

bulk density and friability as indexes

prescription and technology in molding process of Ganershu pellet were investigated

pellet was prepared by fluidized bed side spray pelleting method. Result: Optimized pellet forming prescription and technology parameters were:relative density of liquid was 1.12-1.16 g·mL-1

6% talcum powder as antiadhesive agent

rotating rate of spray solution pump 4 r·min-1

atomizing pressure of 300 kPa

height of turntable of 5 mm

speed of turntable of 300 r·min-1

inlet air temperature of 75 ℃

fan frequency of 25-35 Hz. Appearance of Ganershu pellet prepared by fluidized bed side spray pelleting method were smooth with high roundness

yield of pellets was 86.7% with particle size between 600\|900 μm. Conclusion: This optimized molding technology of pellet was reasonable and stable.
