Meeting a pressing Need: Project Appraisal of the Oilseed Ram Press and Approaches to Implementation

Vitagoat Steam Boiler
Malnutrition Matters, Ottawa, Canada

Steam boiler: Operates on wood or other solid fuels or liquid gas. Steam-injected pressure -cooking can be 10 times more fuel efficient than traditional open fire cooking and more efficient than improved stove-design cooking. Water is heated in an inner chamber and the resulting steam is re-heated in a tube, creating a “superheated steam” that is much hotter than regular steam. The steam is then fed into the cooker. The boiler is inexpensive to build, safe, and can be taken apart for cleaning, which is critical since most boilers accumulate scale on their inner shells and eventually fail.

Kick Start Oilseed Press

The press extracts oil from sunflower, sesame, and other oil seeds. The filter produces clear, cold-pressed, nutritious cooking oil ready for sale or consumption. The seedcake by-product is valued as a high protein animal feed supplement.
