Preheating Rotary Oven Machine

When the rotary furnace is in operation, hot gases pass through the chamber to perform the heat treatment. Generally, the hot gases pass through in the opposite direction than the sample, but depending on the application requirements they can also pass through in the same direction.: an oven comprising one or more horizontal circular tables on a vertical axis that turns so that work can be introduced at one radial position and removed at another after heat and rotation have completed the process.Rack ovens use convection heat, a form of air circulation where the heat is transferred by a fan to the baking products. The hot air produced by heating elements or a gas burner and the fan distribute the air throughout the baking chamber. The oven rack also rotates to ensure an even bake.
