| Advantage |
This
design is further simplified in an attempt to
lower the construction cost, weight of the equipment
ot ease on-farm transportation and to enhance
ease of operation
Feeding of tubers is simplified and easy
The unit can be fitted with either:
1. Metal sheet drum (like the MK 1-3)
2. Hack saw blade drum (based on Latin
America models); the hack saw blades can be either
mounted in a wooden drum or a metal pipe
3. Wooden Drum
with pins (based on Vietnamese models) making
the model ideal for fine grating and starch extracion

| Disadvantage |
The distribution of particles is wide as the grating
duration is very short while in general the mashed
cassava is still coarse.
Coarser mash might still contain certain levels
of cyanide as not all the cells have been damaged
