Safety Tips for your Commercial Deep Fryer


The deep fryer has become a very popular kitchen appliance in most commercial kitchens. Perfect for chips, battered fish, and many other food dishes. A busy kitchen is not complete without a commercial deep fryer

However, that large quantity of boiling oil can pose a few risks and you want to avoid as many accidents as possible. Keeping your commercial deep fryer, and the oil you use, in tip-top condition, is one of the best ways to do this.

Here are four health and safety tips you can use to keep your deep fryer oil clean, tasty, and safe to use.

Change Deep Fryer Oil Regularly

Changing your commercial deep fryer oil is not only important to keep your fried dishes as delicious as possible, but your oil will also become less usable as time goes on. 

Although oil can safely sit in an unused deep fryer for up to six months, it should be changed regularly if it is used often.

Deep fryer oil should be changed every 6-8 uses for non-breaded items and every 2-4 uses for fatty meats and fish. Always change your oil if you notice changes to its composition or if it shows signs of oil degradation. 

Here are some things to keep an eye out for that will let you know that you need to change your oil:

  • Oil smokes at a lower temperature than usual
  • It takes on a darker colour
  • It starts to smell bad
  • The oil becomes thick and/or foamy on top

Storing Your Deep Fryer Oil

If you aren’t using your deep fryer oil, stop storing it in your commercial deep fryer. Although this is commonly done, it is far safer to keep unused oil in a sealed container that keeps out light and store it in a dry, cool place. 

If you store previously used oil, make sure you filter the oil well. You want to ensure that no food debris is left to spoil your deep fryer oil.

Dispose Of Your Deep Fryer Oil Correctly

Pouring oil down the drain is possibly one of the worst things you can do. It can clog your drains and result in having to fork out more cash to get the problem fixed. You may even end up breaking local business laws by doing this.

The best way to dispose of your commercial deep fryer oil is to decant it into a sealable plastic bag or bottle and pop it into your rubbish bin. 

Alternatively, you may have an oil recycling organisation near you that will accept used oil and will recycle it for you.

Use A High Smoke Point Deep Fryer Oil

Our commercial deep fryers can heat to hot temperatures and the last thing you want is for your oil to set on fire because it just doesn’t have the right smoking point.

A smoking point is effectively how hot your oil can be heated before it starts smoking and goes bad. 

Some good, high smoke point oils we recommend are:

  • Vegetable oil
  • Canola oil
  • Peanut oil (be wary of customers with peanut allergies)
