Design and Development of Leaf Protein Juice Extraction Machine

The rate of malnutrition in the developing countries is increasing as a result of increasing population, poverty, and lack of awareness on appropriate nutrition. Leaf protein in spite of its observed similarities with animal protein, is the least tapped of all protein sources. This study presents the design and development of a machine for extraction of protein juice from a highly proteinous leaf and fruit. The machine is family-sized with low power requirement, easy to operate, and fast. The machine has extraction efficiencies of 97.9 and 98.9% for leaf and pineapple. It is therefore suitable for the extraction of leaf protein juice and affordable to the predominantly low income groups in the developing countries.
