When you think of fried food, you probably think of greasy, unhealthy dishes. But what happens when you put ice in a deep fryer? Surprisingly, ice can be used to create some pretty unique deep-fried foods. 

If you’re curious about what happens when you put ice in a deep fryer, read on to find out more. You might be surprised at what you discover.

What happens when you put ice in a deep fryer?

If you put ice in a deep fryer while the fryer has hot frying, it can cause an explosion. It is because the boiling point of ice is 212oF while the smoke point of a typical oil is greater than 450oF. A mixture of two substances having such temperature differences can cause a steam reaction leading to an explosion and fiery surges.

What is ice? How do we technically define it?

Ice is a solid, crystalline form of water that typically appears white. It forms when water freezes and is widely used as a cooling agent.

When water freezes, it expands and becomes less dense than liquid water. This is why ice floats on top of the water. The molecular structure of ice is similar to that of liquid water, but the molecules are arranged in a lattice-like structure.

Why does ice destroy a fryer?

A fryer is cooking equipment that uses oil to cook food. Introducing water into the hot oil causes a violent reaction that can destroy the fryer. This is because water has a lower boiling point than oil, so when it is added to the hot oil, it vaporizes quickly and expands in volume. This sudden expansion causes an increase in pressure inside the fryer, which can cause the fryer to explode.

Ice can also destroy a fryer because it can cause the same violent reaction as water. This is because ice also vaporizes and expands in volume when it melts. The sudden expansion of ice can also cause an increase in pressure inside the fryer, which can lead to its destruction.

What happens if water gets in a deep fryer?

If you’re deep frying at home, the most likely scenario is that you’ll accidentally drop some water into the hot oil. This can cause the oil to splatter and sputter, and it’s a serious hazard. The water will instantly vaporize and turn into steam, which can cause severe burns.

But what if you deliberately add water to a deep fryer? It’s not something we recommend, but some people do it to put out a grease fire.

If you pour water into a deep fryer that’s already hot, it will again vaporize instantly and create a dangerous situation. The best way to extinguish a grease fire is with a fire extinguisher, not water.

Is it OK to boil water in a deep fryer?

Yes, you can boil water in a deep fryer. Boiling water in a deep fryer is a great way to clean it. The high temperatures of the boiling water will kill any bacteria lurking in the fryer, and the steam will help loosen any grease or food particles stuck to the sides.


In a deep fryer, ice will quickly melt and turn to steam. This can potentially be dangerous if the steam comes into contact with the hot oil. If you choose to put ice in a deep fryer, it’s essential to be very careful. We recommend avoiding putting ice in a deep fryer unless it is unavoidable.
