To answer the question on air getting into the honey. As long as you do not try to suck the honey into the product cylinder faster than the honey can flow into the discharge, you should get no air using the filling mechanism. Using the auger would most likely pull the most air into the honey, if not careful. It the honey doesn't cover the auger it will pull air bubbles into the honey on each revolution, so have enough honey to cover the paddles when it is mixing and do not agitate while filling until you get to the last in the tank and then use the auger to move the honey down to the discharge.
