Electric Pressure Cooker or Slow Cooker: What is more energy efficient?

There are so many new models of Electric Pressure Cookers on the market now.  The new sleek modern models make meal prep easy for us to deliver amazing home cooked meals after busy days. 

When comparing the Electric Pressure Cooker against the Slow Cooker, the winner was clear.  The Electric Pressure Cooker not only saves you time, it saves energy is several different ways. 

Here are four ways an Electric Pressure Cooker can save energy;

1. Air-Tight Lid

A pressure cooker comes with a lid made ofaluminum or steel and has an air-tight seal. This design enables it to build uppressure of around 5 atmospheres in the container. As pressure builds up, theboiling point of water rises. This creates steam that ends up reaching atemperature of about 150 degree Celsius rather than the 100 degrees Celsiuswhich it clocks at normal room temperature. Therefore, the food is cooked highertemperature than using conventional cooking pans.

2. Steam- An Excellent HeatConduction

Steam is able to transfer heat by conduction and convection in a much better way than water or air. To illustrate this, think about how you can easily pass your hand in a 200 F degree oven without getting burned, but if you try placing your hand in a pot of boiling water (100 degrees), you will burn immediately. This is because water (or steam) is a good conductor of heat, whereas air doesn’t. These effects of steam reaching higher temperatures and its ability to transfer heat allow food to be cooked faster using less energy.

3. Higher cooking temperature can be reached

Water boils at 100 degree Celsius, at which it turns into steam. However, the temperature doesn’t increase any further until all the water has turned into steam. This means that boiling water will remain at 100 degree Celsius regardless of how long it boils. This limits the rate at which your food cooks.  But with a pressure cooker, boiling water is converted to steam by increasing the pressure inside the pot. By trapping steam in the enclosed space through an airtight lid, the longer the water boils, and the more the steam is built within the pot.

4. Small Pressure Outlet

Pressure cookers are fitted with a smallpressure outlet system that is situated in the middle of the lid. It opens whenthe steam has reached the maximum level to prevent the pressure inside frombuilding to unsafe levels. This ensures temperatures remain at high levels evenat constant temperature.

In the end, if you are looking for the most energy efficient product an electric pressure cooker is the way to go.  Enjoy tasty meals in less time with more flavor!
