Africans and the rest of the world have started embracing the use of herbal products. The need to develop machines for indigenous fabrication that meet the standard for acceptability in terms of hygiene and engineering standard necessitated this concept of using steam to extract the pigment from back of trees and leaves especially roselle (Hibiscus sabdariffa L) (red variety) popularly called zobo in Nigeria culled from zoborodo (Hausa language).The red pigment can be extracted through this machine. Reduction in material handling and commercial production is favored with this machine. It comprises the heating section, water section and the herbal material section which lead to the condenser and the mixer where other ingredients are introduced. It requires 2030038 .8 kj as an ideal heat to evaporate the water for extraction using electricity in one hour .Materials used are corrosion resistant materials like stainless steel and plastic.
