The chain arrived from McMaster-Carr last night so today a friend and I hooked up the drive motor for the auger and we did a timing test. The assumption is the pellets will yeild approx. 5000 BTU’s per pound. So after running the auger for a minute we weighed the sample and with the weight we calculated the feed rate at approx. 30 secs every 2.5 minutes. We will have to adjust the rate as needed for the test. I got a great email from a friend with some useful suggestions for the code which is still having issues. I incorporated all the suggestions and look forward to more useful suggestions.
