Stainless Steel Deep Fat Fryers
Why Stainless Steel If you have a modern up-to-date kitchen, chances are that most of your existing appliances are stainless steel. If so, then then you are probably looking for a stainless steel deep fat fryer to match your current décor. Of course aesthetics is only one reason to choose stainless steel over other materials. But it does offer a number of advantages, especially when it comes to things like hygiene and durability. Unfortunately there is no precise definition of what constitutes a stainless steel appliance and many manufacturers make liberal use of the term to describe their deep fat fryers. It can mean anything from a stainless steel cooking compartment to a appliance that is almost entirely made out of stainless steel. Stainless Steel Cooking Compartments Stainless steel is not a good conductor of heat and tends to suffer form 'hot spots'. That's why in more expensive pots and pans it is frequently combined with copper or aluminium to provide a more evenly heated surface. In the case of a deep fat fryer the food is immersed in hot oil so the thermal properties of the container holding the oil are not as important. What is important is durability and ease of cleaning, two properties that are well suited to stainless steel. Stainless Steel Exteriors Stainless steel is expensive so a stainless steel exterior is going to cost more to manufacture. To help reduce costs many manufacturers will frequently substitute plastic in situations where it will not affect the overall look and appeal to the consumer. Unfortunately, plastic does not always wear well in the hostile environment of a deep fat fryer. Grades of Stainless Steel For steel to become stainless it must contain at least 10.5% chromium. Chromium reacts with oxygen in the air to form an invisible chrome-oxide surface that prevents rusting. Higher levels of chromium and the addition of other alloying elements such as nickel and molybdenum enhance this surface layer and improve the corrosion resistance further. Higher end stainless steels that are more resistant contain Nickel (known in the industry as '300 series' stainless steel). One important property of this kind of stainless steel is that it is NOT magnetic. A cheaper kind of stainless steel contains no Nickel at all, only Chromium (known as '400 series' stainless steel). This type of stainless steel IS magnetic. A simple way to check the quality of your deep fat fryer is to see if a toy magnet will attach itself to the side of the case. If so, the deep fat fryer is made out of the cheaper 400 series stainless steel. |
