  • Vacuum Drying: Back to Physics 101

    Catherine Sidman is the Product Manager at Cascade TEK, an A2LA accredited environmental product testing laboratory. They also manufacture high quality vacuum ovens used for drying, curing and vacuum bake-out applications. You can read more on the Cascade TEK blog. Imagine a 1 liter glass beaker full of water sitting at sea level. This water has a column of air gaseous atmosphere comprised of Nitrogen, Oxygen, Carbon Dioxide and particulates that is as large as the mouth of the beaker and sixty-two miles high. Those gaseous molecules and particulates have...

  • Save Money With Low Temperature Vacuum Ovens

    Environmentally friendly vacuum ovens seem to be the name of the game as the "go green" revolution encompasses more sectors of industry. Low temperature vacuum ovens are a prime example of environmentally friendly processing. This innovation produces results that have no environmental impact with discharges that meet OSHA and EPA standards. If the process is performed correctly then the only byproducts should be water and carbon dioxide which can be safely released from inside or outside a facility. If the water mist becomes an issue inside the facility then special...

  • Vacuum Ovens: Dealing with the Atmosphere

    The atmosphere that I ponder is a vast space where stars, moons and unknown planets dwell. However, the atmosphere also refers to the air that surrounds us on a daily basis, which we cannot live without. In fact, some industrial processes and machines, such as vacuum ovens, alter the state of the atmosphere in order to get certain results. Industrial ovens are thermal processing equipment that is used in a variety of ways, most notably to cook food. Vacuum ovens specifically alter the atmospheric pressure within their main body to...

  • Modern Man's Fire: Industrial Ovens and Their Many Applications

    by Marjorie Steele, Editor at IQS There's no question that fire was man's first great invention. Before Homo sapiens discovered how to create and harness fire, we were in most ways more like our closest primate ancestors, the chimps, gorillas and orangutans who spend over half their waking hours just chewing. Not only did fire give Homo sapiens the ability to break down food into more digestible forms, it also gave sapiens the key ingredient for forming metals: heat. Since man's discovery of fire somewhere around 800,000 years ago, we've...

Industry Information

Vacuum Ovens

A vacuum oven is a piece of thermal processing machinery that is capable of controlling atmospheric pressure within its heating chamber. Removing all or some atmosphere during a heat treatment process can reduce the number of variables that could compromise a successful treatment. Oxidization, which is the cause of a form of surface degradation in metals, becomes impossible when no oxygen is present in the atmosphere.

Surface reactions become less likely when the heating chamber’s atmosphere is strictly controlled as it is in a vacuum oven. When a complete or near-complete vacuum is created, convection, which is the transfer of heat between gasses and liquids, becomes impossible. The only transfer of heat in a vacuum happens as a result of radiation, and radiant heat is reliably even in its distribution. Vacuum ovens have a number of advantages over other types of industrial ovens. In drying, negative pressure from the vacuum works together with the heat allowing drying to take place at lower temperatures than would otherwise be possible. Some laboratories use vacuum ovens for drying heat-sensitive materials. Vacuum ovens may be walk-in or truck-in batch ovens or smaller cabinet ovens.

The process of applying heat treatment begins with loading an item or several items into an oven. Unlike with other heat treating processes, the number of kinds of ovens available to heat treating technicians is limited; conveyor ovens are not suitable solutions in vacuum heat treatment. Outside the confines of a vacuum chamber, atmospheric conditions cannot be maintained. Within the vacuum chamber, there would be no use for a conveyor as heat distribution is completely even throughout the chamber. The most likely variety of industrial oven in vacuum heat treatment contexts would likely be a batch oven if several smaller items were to be treated. In the case of a single, large item, a walk-in or truck-in oven would be suitable. The chamber would be sealed after loading the oven, and a vacuum would be created by pumping atmosphere out of the chamber. Any variety of heat sources could be used to heat the newly evacuated chamber; gas-fired ovens and electric heat sources are both used to heat vacuum ovens. The product, once sufficiently heated, is sometimes quenched with an inert gas that allows the product to cool quickly. The gas is then evacuated through heat transfer equipment, and the product is ready to be removed from the vacuum chamber.
