The Challenges of DDGS Caking in Transit

摘要

The solution lies in product temperature, moisture content and storage environment.he challenges of unloading I )istillers Dried Grains with Solubles (DDGS); the major co-product of corn ethanol production, from hopper cars or ship cargo holds at their points of destination have been a major logistical problem facing the marketing of DDGS. Product caking in hopper cars is primarily the major problem when hopper cars turn up "hard" with nonflowable product (Figure 1]. This problem has led to two Class I railroad carriers announcing that they will not permit railroad-owned hopper cars to be used to haul DDGS. Also, a third Glass I carrier does not permit their cars to be used for hauling DDGS, even though the carrier did not make this explicit statement in its tariff.
