Design and Development of Cassava Stem Soaking Machine

Abstract

In this research to designed, created, developed, tested and evaluated cassava stem soaking machine. The research found that cassava stem soaking machine dimensions 1.2 x 3 x 3 meter support soaking bath size 2,400 liter. Installation with 2,500 watt generator used with electric hoist lift the stem and the motor gear control rotation of a crane. With trailer hitch for travelling.

Performance test results found that the field capacity of machine was 132.28 kg/h (320 stem/hour). The fuel consumption was found to be 0.42 liter/h. The cassava stem damage was 0%. The cassava stem with no soaking with chemical in bath was 20%.Economic analysis showed that the breakeven point of the machine in the working area 300 baht per day was 27.76 rai/year with a consequence of payback period within 2.2 year at working area 100 rai/year.
