First post in SMF, and I apologize if it does not directly relate to smoking. Recently scrapped my rusted old gas grill and purchased one of those Blackstone gas griddles. This thing is awesome, but the only problem is that the propane tank starts to freeze up after about 20 minutes of use - the flame slowly dies down as if the gas has run out. I can pick up the tank,swirl it around, and feel the remaining LP inside of the tank, but the tank is frosted over and it is as if the LP has turned to slush. So far in my research it seems that the griddle is drawing too much gas too fast causing the tank/LP to freeze up. I have read that hooking up two tanks could help resolve the problem. Not necessarily using one of those auto switch-overs like a travel trailer, but drawing from both tanks simultaneously. Found this on Amazon that might get me started but was wondering if anyone else had this problem with a gas smoker. I really do not want to shell out $400 for one of those electric blankets, so I am hoping the two tank method will be a more affordable solution. Has anyone experienced this problem?
