Rasper is one of the important machines in cassava starch processing. After the harvested cassava roots are stocked for the processing, they must be washed clean and other hard articles must be removed from the roots, otherwise the rasper machine shall suffer unexpected damages once these hard articles are fed into it. We want to extract starch as much as we can, so crushing is the first important procedure. The main rasping or wear parts inside the Rasper machine are saw blades. To maintenance person or QC persons, Checking the wearness of the saw blades regularly is a important job both for the machine safety and starch quality and productivity.
