Key data

Expansion and modernisation of a silo plant, including infrastructure for receiving, cleaning, storing and loading grain. 
Conveyors are used for transporting grain from the stock to the new plant. The site comprises a closed engine house for receiving and loading grain, including the necessary conveyors, dust extractors and processing equipment, a drying facility and an adjoining silo plant. The design of the plant allows grain to be delivered during harvest, precleaned and dried so that it can be deposited in the silos for stable storage.
