Development and Knowledge Transfer of Bio-Fertilizer Pelletizing Machine Innovation for Communities in Sakon Nakhon Province

บทคัดย่อ

The purpose of this research is to study the effect of operating conditions on granular fertilizer production using the biofertilizer mixing pelletizing machinery, developing strategies for evaluating device’s performance and knowledge transfer. The biofertilizer pelletizing machines can be used to develop the production of bio-fertilizer pellets. The machine framework is 60 centimeters in width, 100 centimeters in length and with a height of 140 centimeters. The machine is tested in two parts. First part is when mixing fertilizer is tested, and the second part is the testing of fertilizer pellets. The compound fertilizer consists a bio-fertilizer, rice bran, water and a biological fermentation. The efficiency of test compressed granular fertilizer ranges from 17.33 to 20.67%. The machine is successful in producing fertilizer pellets at 95.70% and can produces a maximum of 20kg granular fertilizer at a time. The rotation speeds used for the production of fertilizer granules is at 450 rpm. From the field transfer of bio-fertilizer mixing and pelletizing technology, farmers are satisfied with the outcome. The results of the assessment showed an average of 3.64 level of satisfaction of farmers. The results of engineering economic analysis showed that the average cost of work is 1.63 baht per kilogram. The break-even point is after working 21 hours a year and with a payback period of 7 days.
