The developed system can perform in extraction of starch from starch food like tapioca and potato with using of minimum input water for starch washing. The system has 100% pollution free operation and 2/3 power saving equipment compare with the existing plants. The process as follows, The tubers are feed in ETP Plant [11] bed, here the washing process start[12], then tubers are carried by screw conveyer to skin removing zone, here cutting the outer layer(skin) of tuber . by rollers[e] in the peeling machine[13]. The peeled tubers are conveyed [14] to the Grinding Machine [15]. Uncut peeled tubers are entered into the entry portion [1] of Grinding Machine, then its getting a grinding, which convert into slurry form [16]. The slurry [16] flows to the roller presses [17] here the milk [22] and bulb [21] are separated. The milk is feed into shacking kettle [18] for grade separation, and it"s allow for sedimentation process, starch and starch water [23] are separated. MODEL DRAWINGS
