The 9 Gallon Bayou Fryer is one of the most efficient deep fryers on the market today. The 9 Gallon Bayou Fryer is made like a restaurant fryer however it uses propane. Unlike restaurant fryers, the 9 Gallon Bayou Fryer has a v-bottom design that keeps the base oil temperature cooler than the top frying temperature so batter does not burn and oil stays cleaner. This makes cooking with the 9 Gallon Bayou Fryer more efficient. The heat from the propane flows through the tube in the back of the Bayou Fryer and runs all the way through the fryer - rolling the oil. This is what heats the oil. The heated oil rises to a perfect temperature and keeps that temperature perfectly. The 9 Gallon Bayou Fryer holds the heat so well, it uses less propane. We've actually had customers turn the propane completely off and continue frying. The actual burner is not loud at all compared to your jet burners or other propane burners. No more talking over each other! Another point that makes the 9 Gallon Bayou Fryer more efficient is the fact that you can use the same oil over and over and over. Fry fish, hush puppies, fries and whole chickens (without the included carts or with the accessory cart). The 9 Gallon Bayou Fryer does include three (3) stainless steel fry carts (like the ones restaurants use), temperature gauge, drain valve, extension legs, and 10 PSI regulator kit with stainless steel braided hose.
