Getting Started With Different Applications Of Forced Air Ovens In Labs


Flammable Storage Refrigerator

Forced air ovens differ from convection ovens, which is not the case with gas and electric ovens. Instead, the airflow heats a tray that runs right along the back wall of the oven. The air temperature inside the oven is usually 350-450F, and it runs constantly.

The forced air ovens are more precise; require more maintenance, and cost more than a convection oven. Their performance depends on the manufacturer and model of the oven. The heat distribution inside an oven is like a convection system, but there is no net movement of air. Fan-forced convection ovens circulate air around the whole chamber at much higher temperatures.

Understanding the Basics of A Forced Air Oven

Forced Air Ovens are the modern form ofcreating airflow around the cooking area. There are different systems and designs, but most rely on the same principle: An electric blower pumps air through a tube into the oven, causing hot air to rise and cool air to fall. These hot pockets of air expand and collapse as they pass through the oven, moving around it. A few basic points about using forced air ovens are shared below:

  • The forced air oven is mounted above the cooking area.
  • A damper is on the top of the oven to keep the combustion chamber hot.
  • A fan moving at high speeds pulls in and releases air through an adjustable opening or door.
  • The control panel has an “AIR” symbol with three bars, instead of a dial that must be turned all the way up to start heating.

There are some important distinctions between forced-air and conventional convection ovens. The major difference is that a forced-air unit comes with no heating element, meaning its only heat source is the fan inside the chamber itself.

Structure of a Forced Air Oven

A forced air oven combines convection and traditional cooking technologies with a fan to move hot air through the cavity in which food is placed. An electric blower circulates the hot air and cool air through the oven’s cooking chamber, while an adjustable door gives access to the contents of the heat source.

Forced air ovens are usually built with “air” in their name because they create hot pockets of air that move around inside their oven as they cook. These ovens also have vents to allow cold fresh air in. Still, they may not have other ventilation features besides a basic damper to maintain combustion or heating temperatures.

How Does a Forced Air Oven Works?

All forced air ovens create hot zones inside the oven as they bake. The fan in these ovens works similarly to how an electric fan works, but with a forced-air setup, the air moves through an adjustable door and around the oven’s interior. This creates hot pockets of more or less circulating air that cooks can manipulate to get their food cooked to specification.

The most basic forced-air oven will have no heating elements inside it at all. Instead, a fan unit will pull air over a heating element inside the chamber itself. The main advantage of this system is that the heat doesn’t have to travel far, which means it can be regulated more easily.

Different Applications of Forced Air Ovens

Forced air ovens are unique because they don’t have special temperature gauges or dials to monitor their operation. Instead, they have an airflow that needs to be manipulated to cater to the needs of the sample stored in it. Most labs use an electric forced air oven because of its low cost and simplicity. Other uses of these forced air ovens include:

  1. Blending

A forced air oven can be used to help break and mix different reagents and samples. The hot air circulating the oven is carried by the forced air that is blown through the oven door by an electric motor. This cold air will help break down the protein contents of an ingredient, while the hot temperatures will heat it.

  • Drying

A forced air oven can also be used to dry any chemical o biological material that may have been dried as a condiment in a conventional oven. In addition, the high temperatures of a forced-air oven can accelerate the drying process even more quickly than using traditional methods alone.

The forced air oven provides precise temperature control and heat transfer, which means you can use it to mimic many different cooking chambers, such as pizza ovens, rotisserie ovens, steamers, roasters, and more.

Conclusion

Forced air ovens are becoming more popular across laboratories and factories to keep the heat consistent in the heating chamber. Any process/reaction that requires heating under dry conditions can now be achieved with a forced air oven. If you want to learn about Forced Air Ovens, click here.
