There were also many Rice and Paddy Hulling mills facilitating agro based trade. The dried paddy is ready for hulling. In 1885 the modern rice hulling machine was invented in Brazil. These trip-hammers were used for the pounding and hulling of grain. There is a small amount of industry, including canning, textiles, rice hulling, and light engineering. The resulting nixtamal is ground with little or no washing or hulling. Much of this hulling is done through SEMRY in Yagoua. Sulawesi farmers use a unique process called "giling basah" (wet hulling).
