Another possible micro-credit projects for home industry for the poor in third world countries. Farmers can grow their own soyabeans or groundnuts. Unsold soyabeans and groundnuts can be converted into high quality oil which can also be sold.
I constructed a wooden frame made of 1 inch thick plywood for mounting the Piteba. The wooden structure is mounted securely on a table top using 2 "F" clamps.
A one man force is required to turn the crank. As the crank turns, the oil begins to drip out of the Piteba and collected in a glass container (Brand Essense of Chicken bottle). The byproduct, the press cake of crush peanuts is collected at the front end in a metal basin.
Finally, 200g of peanuts is able to produce 70ml of peanut oil. A conversion efficiency of 35%.
Somehow, the soyabeans were not successful in extracting the oil. No oil was extracted.
After one week, the sediments managed to settle down and the groundnut oil becomes clear.

I have one of these Piteba presses - soybeans can't be cold pressed to produce oil, the oil must be extracted using chemical solvents, unfortunately. There are many different options for nuts & seeds one could press using the Piteba though. I myself have had luck using sunflower seeds and hull-less pumpkin seeds.
