Deep Fryers - Did you know

 Deep fryers:

These are appliances that hold a quantity of oil or fat in which food such as chips, fish and doughnuts are cooked. There are two different designs - one that has a flat bottom with the oil heated directly from below and a second type has oil that is heated at a location above the base so maintaining a cool zone below the flame in which old food particles can sink without carbonizing and spoiling the flavor of the food load. There are two methods of heating the oil using this design of fryer. In the first method there is what is known as a V-shaped fryer, with the lower V section below the burner. The second method requires the gas flame to be fired directly into tubes that pass through the mass of the oil. With the flat bottom fryer it is essential that, before each frying all old particles are strained from the oil. The heat input can vary between 8 kW and 40 kW depending on the size of fryer.
