Abstract

This study was conducted for increasing solubility of weaning food by fluidized bed agglomeration. The conditions of the fluidized bed agglomeration affected the physical properties of weaning food. To elucidate the optimal conditions for fluidized bed agglomeration of weaning food, the influence of spraying quantity, spraying rate, binder solutions and inlet air temperature were investigated. Bulk density of agglomerated weaning food was reduced with the increase of spraying quantity. Flow ability of agglomerated weaning food was increased with the increase of spraying rate. Maximum flow ability of spraying rate was on 340g/min being very good condition. Effect of binder solution (fructose 5%, 15%, 30%) was not significant. The best agglomeration was observed when inlet air temperature was 115℃. Fine particle (below 250 ㎛) was reduced from 60.4% to 7.0%, significantly. Mean diameter of particle increased from 233㎛ to 542 ㎛ showing growth rate as 133.6%.
