CROPLER will allow grain traders, mills, grain quality inspection companies and farmers to make the grain sampling process faster, more efficient and more precise, with an automated grain sampling drone. Current grain sampling methods are either slow and unreliable or expensive and problematic to install. There is no method that could be used by all market participants. CROPLER could be used by mills, grain traders, grain quality and verification companies and farmers to sample grain, regardless of the type of storage (flat storage, silos, trucks and wagons).
