This facility is part of the company's extensive operations in sugar refining and distribution across the United States. The location plays a key role in their logistics and supply chain for sugar products.
Norbert Rillieux was a 19th-century African American engineer and inventor, best known for developing the multiple-effect evaporator, which revolutionized the sugar refining process and significantly increased efficiency. Henry Blair, also an African American inventor, is noted for being one of the first to receive a patent in the United States, in 1834 for a seed planter, and again in 1836 for a cotton planter, contributing to agricultural advancements. Both men made significant contributions in their respective fields, showcasing the impact of African American innovation in history.
