Sample cleaner MLN helps in making stock-related determinations associated with grain crops and
grading the said crops.
After the sample has been weighed, pour it into the deawner when the deawner base is closed.
The machine starts when you close the cover of the filling container and switch the control switch to ON.
The deawner base automatically opens after a period of time specified on the potentiometer (freely
selectable between 0 and 80 s).
The light dirt such as dust is extracted by the aspiration process and deposited by the cyclone in the dust
collection bag.
The sample proceeds via the straw sieve that sifts larger impurities, after which it proceeds via the sand
sieve. Sand and small impurities such as weed seeds fall through the sand sieve.
The impurities, sand and weed seeds go into the front left collecting pan and the cleaned sample goes
into the front right collecting pan.
