Complex Approach to Conceptual Design of Machine Mechanically Extracting Oil from Jatropha curcas L. Seeds for Biomass-Based Fuel Production

Abstract EN

One of important sources of biomass-based fuel is Jatropha curcas L.

Great attention is paid to the biofuel produced from the oil extracted from the Jatropha curcas L.

seeds.

A mechanised extraction is the most efficient and feasible method for oil extraction for small-scale farmers but there is a need to extract oil in more efficient manner which would increase the labour productivity, decrease production costs, and increase benefits of small-scale farmers.

On the other hand innovators should be aware that further machines development is possible only when applying the systematic approach and design methodology in all stages of engineering design.

Systematic approach in this case means that designers and development engineers rigorously apply scientific knowledge, integrate different constraints and user priorities, carefully plan product and activities, and systematically solve technical problems.

This paper therefore deals with the complex approach to design specification determining that can bring new innovative concepts to design of mechanical machines for oil extraction.

The presented case study as the main part of the paper is focused on new concept of screw of machine mechanically extracting oil from Jatropha curcas L.
