Feed Silo Inventory Analysis: Manual Unloading Issue and 'Auriken' Shipment

We have observed that each silo retains around 700 to 900 tons of previous goods before being loaded with new goods. The recipient has explained that due to the flat bottoms of these feed silos, unloading all the goods requires manual clearance; otherwise, several hundred tons of goods usually remain at the bottom. Currently, the inventory of silo 6 is 2589 tons, and based on the documents, approximately 900 tons of goods are from the ship 'Auriken'.
