After wet sugar is dried, screened and cooled, it is sent to large bulk storage silos/domes, each of which can contain up to 50,000 tons. From the storage silos, the sugar is either delivered via trucks or transferred to a packaging silo to be packed in bags. Challenges: Raw sugar is stored in very large silos or domed warehouses where it is widely distributed in order to use maximum capacity. The stickiness of the sugar leads to random formations of material build-up and rat holes inside the silo or dome. Both silo or dome size and the material properties make it extremely challenging for users to continuously assess sugar inventory levels.
