Performance of the crown hand oil press
This hand oil press which named CROWN, is a homemade oil press machine with the high extraction efficiency, continuous expelling and hand operated (no external power source required). Hand crank modeling design makes the operation much easy. Oilseeds can be expelled perfectly (including seed coat) by this hand oil press. And it is almost no maintenance required.
Quality requirements of the seeds
Oilseed has to be well dried, but not too dry (app. 8 - 10 % moisture)
No deshelling required except for groundnut, walnut and hazelnut
Oilseeds should be freed from any stones, sticks and sand before expelling.
Big seeds such as walnut, hazelnut, oil palm kernel, coprah and babassu need reduction in size but should not be grinded.
Important for good results
Moisture content of the seed should be 8 - 10 %.
If too dry (artificially dried seeds or dried in arid regions):
Press oil cake in the cap stone hard / no oil production.
If too moist:
Press cake flows back to the oil slid / no oil production.
