A World First - A Solar Powered Chocolate Factory
We wanted the most efficient machines possible, because chocolate making is a very energy-intensive process for a solar-power system to handle. For over two years, we experimented with designing our own chocolate making machines, as well as refurbishing a couple of antique machines.
On all these machines, we used DC, permanent magnet motors, which allow efficient direct powering from the solar-power system. In my chocolate project partner and friend Doug’s barn in Oregon, we built and tested several generations of machines, including wood-fired roasters, winnowers, grinders, and cocoa butter presses.
We tested them by processing cocoa beans we imported from Grenada. After many months, lots of brainstorming, and a few dead ends, we had a machine line we were happy with, and chocolate we were addicted to. We packed up all our machinery and solar-electric equipment, and sent it on a ship to Grenada.
