The construction and working principle of a hot air oven

The hot air oven is an electrical device that is used in various industries. The device uses hot dry steam for the sterilization of products used in industries. Industrial ovens have different types that are used for the different applications like Annealing, Curing, Heating, Baking, Drying, Preheating, Sterilizing, etc. There are various types of industries that use various types of products to be processed as final product. The application and the type of process are the most important when buying a furnace for your industry. It is always better to choose the product wisely after analyzing the necessary points.

When choosing a hot air oven, pay attention to the following points:-

• inner chamber dimensions

• Inner chamber construction

• Shelf number and option to remove

• Temperature range

• temperature sensitivity

• power supply

• heater supply

• General dimensions of the device.

• unit net weight

Working principle of a hot air oven

• The device works well to sterilize products manufactured in different industries using dry heat to keep them safe.

• It is good for killing the bacteria of the products in the sterilization process, which is the main reason for the processing of the products.

• The inner chambers of the devices are equipped to create a pressure that provides good air circulation.

• The device is used in pharmaceutical applications proving it safe for baby products.

• It is also used in the heating, drying and baking processes, in addition to the sterilization process of the products.

Robust construction of a hot air oven

• All the outer casings of hot air ovens are coated with a thick layer to give it better resistance from the inside out. This provides a strong, highly scratch and heat resistant surface for a long lasting attractive finish for the device.

• The internal surfaces (including doors) of the device are made of a high-strength material that can be aluminum or stainless steel to eliminate sharp edges.

• The device’s double-walled chamber is filled with high-quality insulation to prevent heat loss during operation.

• The oven door has a gasket that ledges the sides of the doors to fit perfectly into the fixed guides. In addition, insulating materials are filled between the two walls of the oven to prevent heat loss.

• The capacity of the device varies according to the use and the requirements of the industries. The power supply also varies in the same way that the capacity of the device varies depending on the voltage and frequency used.
