I am looking to build another trailer [ "Mr Tony's Kitchen" ], this one will have a hood, deep fryers [ 2 ] a gas grill Confused and 6 burner stove top / oven. Any clue as to what kind of usage on propane this will have?? The oven and stove top will have somewhat limited usage, but assuming 1 deep fryer will always be running when open, grill as needed. ANY input appreciated - even how long a 35-40# deep fryer will run on a 20# tank will give me a base to guestimate usage. Just something I havent had to figger out to date...
Thanks in advance
Tony

There is 91,600BTU/gallon for propane. Full a 20lb is 4.73 gallons of propane or 433,268 BTU per tank. (Although most places do not fill a 20lb tank completely full so it could be less for you tank) So with those numbers lets say you have a 40# fryer that 90,000 BTU burner that has a 30% duty cycle, so it would run an average of 18 mins an hour thus burning 27,000 BTU of gas an hour or 1.25lb/0.29gal per hour. But that is best case numbers.

I would run with a minimum of 30 or 40 lb tank, never want to run out.

Your volume usage will also be a factor in what size tank or tanks you select. We always run two tanks on a manifold, only one on at a time, then switch to the backup when the primary runs out. We balance for at least a full days usage on the primary, so at any time we have at least one day supply on board, assuming you replenish your backup next day.
With that many appliances I'd test your volume usage before purchasing tanks if possible.

I purchased 2 - 100# tanks online, but not here yet...Have a gig next week where I need the fryers [ bought 2 yesterday] I have several 20# tanks for that gig.
Thanks for the input guys!

I tried those 100 pound tanks, and now run two 40s with changeovers. Of course if you have access to fill in place LP the 100 pound tanks will provide plenty of fuel!

We currently use 100 lb. and 20 lb tanks depending on the application. For the versatility we have been playing with the idea of switching to 40's for everything. The big tanks seem to get heavier every year Smile
