Deep frying is a thermal process of food preparation in food service, carried out at relatively large scale industrial duty.
Industrial fryers are mostly continuous deep fat fryers, containing a frying vessel and frying oil circulating system.
The oil is availed heated by electric resistances or thermal oil. It is important to provide a large heat transfer area (less watts per unit area) in order to avoid local overheating of the oil.
The oil should be continuously filtered to remove particles that catalyze oxidation. At the same time, fresh oil is added to make up for the oil intake by the product.
