Uji Performansi Disk Mill Dan Vibrating Screen (Discreen) Dalam Pembuatan Tepung Mocaf (Modified Cassava Flour)

Abstrak

Cassava is one of the local ingredient that can be used to make mocaf flour (modified cassava flour) as an alternative to subtitute the wheat flour. Mocaf is a cassava flour that modified through fermentation process by lactic acid bacteria, so that the functional characteristic change and can be used to substitute the wheat flour to make the product that using wheat flour. The purpose of this research is to determine the performance of disc mill and vibrating screen on the process of making mocaf flour in terms of the chip incoming water content effect and the mesh size of screen for mocaf flour according to SNI. The result of the research conducted if the exact water content is 12.5% with 99.3% yield and siege capacity is 2.9 kg/h. So to determine the performance of screener conducted research by varying the size in 60, 80,100 mesh and different sieving time. The result of the research found the optimum time is nine minutes with the average undersize around 87.84%, while for the lowest flour water content  is around 12.8% from the particle that out in 60 mesh sieve.
