To coldzone or not to coldzone, that is the fryer question

Starting off with the correct deep fryer for your restaurants application is the first step in ensuring that your fried foods deliver the high quality taste that customers demand and meet the health requirements that federal and watchdog agencies are pushing for. Finding out which deep fryer will work best for your restaurant will not only deliver a better quality and healthier fried food but help extend the oil life in your deep fryer. To find the right fryer for your restaurant equipment needs you must evaluate your menu.

There are numerous types of fryers on the market today, so much so that choosing the right one can be an overwhelming task. It is best to start at the most basic level and the your way down to determine what type of fryer you need when looking at restaurant equipment. At the most general level there are two types of deep fryer, those with sediment zones and those with out. Your menu will decide what type of fryer that your restaurant will need. The sediment zone enhances the fry cycle by allowing pieces the pieces of breading on the fried food that separates from the main bulk to drift away from the cooking area into a cold zone. We can break this down again into three basic types of fryer, each with it’s own benefits which are again determined by the type of fried food on your menu.

Open-Pot Fryers have a deep, almost V shaped, sediment zone at the bottom of the fryer with the heating elements located on the outside of the frypot. This type of fryer performs well in a range of applications but are best used for lightly breaded items like prepackaged foods and french fries. A nice side benefit to an Open-Pot fryer is the fact that cleaning is relatively easy as the entire pot is accessible.

Tube-type Fryers have a wide cold zone located all the way across the bottom of the frypot with the heating conductors located above the cold zone but again all the way across the frypot. With such a wide zone to collect sediment, the tube type fryer is a good choice for wet and heavily battered items like fresh fish and onion blossoms.

Flat-bottom Fryers have no sediment collection zones. The frypot sits directly on top of the heating element and any sediment that falls off the food item stays in the fry area. Like the Open-Pot fryer, the Flat bottom fryer is easy to clean and are generally best for cooking items that float on the top of the frying oil during the fry cycle Wet battered fish would be a prime example of an item that this type of fryer would work best for.

We’ve covered quite a few topics regarding deep fryers and how to get the most out of your fryer oil and friend foods, however there is still one area that needs to be covered and is really the foundation of everything we’ve talked about so far. To truly increase the life span of your oil and provide a consistently high quality fried food while maintaining healthy food guidelines, you must know your equipment inside and out.

Proper deep fryer techniques

As we’ve already touched on, fry oil will change it’s composition as it interacts with food placed in it, the heat from the heating elements, and the oxygen in the air. As a result of this chemical interaction with these elements by-products are created in the oil which changes the overall make-up of the oils characteristics. In addition, food particles, water, and the various starches in the batter start to enter the oil as contaminants and contribute to the breakdown of the oil’s quality.

There are five easy areas to watch out for that can greatly increase the quality and longevity of deep fryer oil. It is important to try and limit the amount of exposure the oil gets to crumbs, air, salt, water, and heat. All of this can be accomplished by using the following good frying practices:

1) Once the baskets are loaded shake them out before moving them into the frying area. This will knock off any of the loose crumbs from the product allowing them to be disposed of easily instead of falling off into the fryer oil.

2) Filter the oil in your deep fryers on a regular basis. Depending on the amount of use your deep fryer sees, this could be nightly or bi-weekly. Filtering frequently will remove the solid particles that have fallen off into the oil during regular operations as well as un-dissolved salts.

3) If the fry oil becomes contaminated by an unexpected substance you should follow the safe handling procedure and dispose of the oil immediately and thoroughly clean the deep fryer before using it again.

4) Read the cleaning instructions of your deep fryer, follow cleaning and oil replacement guidelines set forth by the manufacturer. Proper care and maintenance of your fryer will help ensure a long product life and help avoid any fryer defects that could cut down on the life span of your fry oil or cause inconsistencies in your fried food.

5) Keep your fry oil at it’s optimal temperature at all times. Doing so will help avoid situations where food is cooked at too high of a temperature or much faster than expected, thus allowing for a consistent quality to your fried food. Avoiding fluctuations in temperature will also help increase the life span of your cooking oil. It is unavoidable that cooking oil will fluctuate in temperature while actually cooking but keeping those fluctuations to a minimum will be beneficial. Most oils are recommended for a 330°F to 350°F operating temperature at the start of a cooking cycle with a drop to 330°F for a brief period at the start and then returning to between 330°F to 350°F. However, one should always consult with the manufacture of their cooking oil for specific usage guidelines as many of the trans fat free oils may require different operation temperatures
