Jiffy Precision Mill

A bit about the new old Jiffy Precision Mill. It is a bare bones simple electric steel burr grain grinder. It is made in the US and likely no longer in business. It grinds a nice fine flour but maybe not quite as fine as a high quality stone mill. But for the basics it is great. It did have one design flaw that was easily remedied. The adjustment knob covered the set screw that held the setting while you grind your grain. The knob covered access to the set screw when in a super fine setting. This caused the grain to act like a clutch disc and turn the adjustment knob while grinding until the adjustment was so tight it would no longer allow grain through the grinder. The remedy was changing the knob bolt to a longer one and insert washers on one end to push the bolt head in further and the other end to push the adjustment knob out away from the set screw so you can tighten the set screw to hold the adjustment while grinding. The fix work perfectly. It does not take too much tension to hold the adjustment. I did find it would be better to grind a bit coarser then just run it thorough again on a finer setting. It seemed to like that. The hole for dumping in the grain is the biggest issue as you can’t just dump grain in and start it up and even when it is going you can’t over load the funnel. But if you feed it with a little bit at a time it works. The inner gear that moves the grain is just a fat coil spring. It is a simple mechanism but it does work. Im pleased with the results and it will make pretty quick work out grinding your flour. I know that grinding flour in a steel mill will warm up the flour as it is ground into flour but I can assure you that the heat generated is not even close enough to cause any degradation of the flour as is commonly stated in these types of videos. It is total Bull that the warming of the flour will in any way degrade the quality. Warm won’t do any harm. Hight heat can but warm can’t. Don’t by the hype about grinders making the flour warm. Warm you can hold in your hand. Hot cooks and will burn. This does not make the flour hot. Since they don’t make these any longer I can’t recommend but if you have one and tossed it away because of the adjustment issue with the setscrew I can assure you the fix is easy. There are other burr grinders out there. Don’t be afraid of them. My next one is to try out the KitchenAid Grain Grinder. Im looking to get a vintage one that uses a glass jar as the flour catch.
