Below is email exchange about corn.. One skid had fatty pellets another where less than a 1/4". I forwarded on your email to my plant manager in NC and he told me that for a very brief period in 2010 we did make Freedom Fuel at a 7/32nd diameter and then switched to 5/16th. He also said that if adjust the combustion air on your stove a little you should get a better burn with the smaller pellet. As far as the corn there's a tiny fraction of the hundreds of thousands of tons we produce each year may have trace amounts of corn in them as industry standard practice denotes that corn be used to clear the wood from the holes in the die whenever the pellet mills are shut down for regular maintenance or emergency repair. Failure to do so will cause the wood to plug the holes permanently rendering the $10k die useless. Corn is far more expensive than wood and as such would never be used as a filler in place of wood by any right minded wood pellet producer. Furthermore corn burns virtually identical to wood and therefore will not cause any adverse effects to a stove or exhaust system. I hope this answers your questions and thank you for choosing Freedom Fuel this season.

The image depicts pellets from 2 skids, both sacks labeled 7. 6437592365. 3 On a side note, the sacks indicate 100 percent wood. Why do the 5/16ths pellets contain a fair amount of shelled corn? Thanks for taking my call today.
