Overview

OSE principles suggest minimal use of petroleum products, which often means the substitution of locally produced vegetable oils. Oil crops are also likely to be grown for edible cooking oils. In either case, appropriately-scaled oil processing technology is required.

Applications

Crops

  • Canola (modified rapeseed)[[4]]
  • Soybean
  • Sunflower[5]
  • Flax (Linseed)

Oilseed pressing on Appropedia at Library4Farming Description of conventional Refined/Bleached/Deodorized(RBD) process in this patent application

The cage press method of expressing oil involves loading seed into a squeezing compartment, applying at least 500psi to crush seed and express the liquid oil, then removing the remaining solid oilcake. It seems that with appropriate simple modifications (wall perforations in the upper end of the compression chamber) the CEB Press could perform this function very effectively.
