| titleOfInvention | The process method of microencapsulation of ferrous sulfate |
| abstract | A process method of microencapsulation of ferrous sulfate, which is characterised in using glycerol monostearate (GMS) as the wall material for its solubility to acetone and the convenience in low temperature spray-drying to undergo the microencapsulation of ferrous sulfate; steps of the method consist of: adds 3-15% of GMS into acetone solution; agitates the solution at high speed (500 rpm) for 5 minutes until complete dissolvement; adds 4-8% of ferrous sulfate into the solution and agitates at the highest speed (500-1000 rpm) while maintaining the solution at complete homogeneous suspension; discharges the suspension into spray-dryer at the feeding rate of 1200 ml/h; the operating conditions of the low temperature spray-drying are: (1) inlet gas temperature: 50 to 80 C, the obtained microencapsule has the effect of hindering the oxidative property of ferrous sulfate, specifically the 50 C group has better result but with lower yield and ferrous content, for avoiding the high temperature oxidation to ferrous sulfate, it is better to choose 60 C; (2) spray flow rate: 400 to 700 1/h, all the obtained microencapsules have the effect of hindering ferrous sulfate oxidation, specifically the 400 1/h group has better result; the 600 1/h group has higher yield (35.96%); the 700 1/h group has higher ferrous content; therefore, it is appropriate to adopt 600 or 700 1/h. |
