Final publish I explored how I’d go about turning our manufacturing course of fully farm-to-skin. At this time I need to speak about one of many inspirations for eager to take extra management over our uncooked materials manufacturing, and probably one of many instruments that might assist us achieve this: wind oil. A number of years in the past, Dutch designer Dave Hakkens made a glossy and useful wind-powered oil press. It’s mainly a mini-windmill on your yard. All it’s important to do is collect the nuts, place them within the hopper, and look forward to the wind to do the work.
Wind oil design
The wind oil-machine is about seven toes tall. The wind turbine seems just like that of the previous mid-western agricultural windmills. It has fifteen blades made out of sheet steel. A worm drive gear association sits behind the turbine, which turns the spinning of the blades into sluggish, highly effective rotation round a vertical driveshaft. The driveshaft extends to an auger that’s housed in a copper press meeting, which is positioned about midway up the windmill. There’s a platform underneath the copper press, with house for 2 bottles. One bottle collects the oil, whereas one other bottle collects the leftover pulp.
Different oil expellers
The closest factor in the marketplace to Dave Hakkens’ wind oil press is the Piteba hand crank oil expeller that’s, apparently, additionally from the Netherlands. The mechanism of the Piteba oil expeller additionally makes use of an auger that rotates inside a steel tube, and it equally separates the oil from the pulp. Nevertheless, the Piteba mechanism is oriented horizontally in comparison with the wind oil machine, no gear meeting is required to show horizontal rotation into vertical, and a hand crank, in fact, provides all the required torque.
Making cold-pressed oil
Each Hakkens’ wind oil machine and the Piteba produce chilly pressed oil, which simply means no warmth is used within the oil extraction. (If warmth is used, extra oil might be extracted, however warmth might alter the style of the oil.) The Piteba web site mentions that it could press any seed nut or dried fruit that’s at the very least 25 p.c oil. I’d anticipate the wind oil machine to have related capabilities. A few of the nuts and seeds Dave Hakkens likes to press embrace hazelnuts, walnuts, linseeds, pumpkin seeds, and sunflower seeds! In case you learn our post on creating a farm-to-face soapmaking operation, you’ll know why I’ve a particular affinity for pumpkin seeds and sunflower seeds.
One of many options of Dave Hakkens’ initiatives are that they’re open supply. Sooner or later I feel I learn that he meant to make wind oil plans accessible so we will all construct our personal wind oil presses. I emailed him in 2015 or so asking if he would ship me some plans, and he emailed again saying he was too busy! Effectively, it seems like he’s been engaged on spreading a DIY plastic recycling motion all all over the world, so I suppose that’s extra essential than urgent a number of seeds.
Metaphor wind oil?
Is a wind oil press in our future? Perhaps. A lot of the items look fairly simple to duplicate, besides the auger. Perhaps you may get a substitute Piteba auger someplace. If not, it seems like there are many Piteba oil expeller hacks documented on-line, together with…one with a bicycle? However first, now we have loads of half-finished initiatives, reminiscent of rising our income a bit by getting extra of y’all to the web site. So, maybe, not within the close to future. However…you by no means know.
