Oil Extraction Yield Calculator

Work out oil extraction yield instantly with clear inputs, formula shown and shareable results.

About Oil Extraction Yield Calculator

Oil recovered is seed weight x oil content x extraction efficiency. Screw expellers recover 80-88% of the oil present and leave 6-10% residual oil in the cake; solvent extraction reaches 96-99% but needs a hexane plant. The cake is the balance of the seed weight and carries real feed value.

Formulas

Oil recovery

Oil in seed = seed x oil content %; oil recovered = oil in seed x extraction efficiency

Cake

Cake = seed weight - oil recovered

Worked example

With the default values below, Oil Extraction Yield Calculator returns Oil Recovered of 357.00. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

Why does expeller cake still contain oil?

Mechanical pressing cannot rupture every cell. The 6-10% residual oil is why solvent extraction plants buy expeller cake to extract further.

Does double pressing pay?

It lifts recovery a few points but raises energy cost and can darken the oil. Compare the extra oil value against the additional energy and throughput loss.
