Explanation:

In the 18th century (1737 as per a plaque at the main entrance), at Betty's Hope, twin windmills were used to crush sugar cane. Initially, the windmills had three vertical rollers to crush the cane fed by two men and it could crush and extract only 60% of cane juice even after two rounds of crushing.

The windmills were used to grind sugar cane. This is a print of a working windmill, as they appeared in the 18th or early 19th century. The cane arrived on carts drawn by oxen or mules.
