Wet Bulk Storage Sugar mills in most parts of the world operate for only about 6 – 7 months Peru is an “exception exception” – sugar mills operate 11 months Bagasse long term storage is required After moist depithing, it is stored in wet bulk piles (80% or higher moisture content) to control micro- biological action in the pile 10
Wet Bulk Storage Bagasse wet bulk piles are very large can be the length of several football fields by 100 m width by 23 – 25 m high length depends on site arrangement usually the bagasse is pumped up to the top of the pile using a boom stacker which can be moved as the pile grows water is continually recirculated – as it seeps though the pile, it is collected in tanks and pumped back to the top to keep the pile wet Bagasse wet bulk piles are very large. They can be the length of several football fields by 100 m width by 23 – 25 m high. The length often depends on site arrangement. Usually the bagasse is pumped up to the top of the pile using a boom stacker which can be moved as the pile grows. Water is continually recirculated. As it seeps though the pile, it is collected in tanks and pumped back to the top to keep the pile wet. Bagasse is retrieved from the pile on a first-in, first out basis so that the bagasse being used is always about the same age. 11
