The main structure of the drying oven is shown in the attached figure: Front sectional view
2Overview of Working Principle
This drying oven is a drying equipment with circulating ventilation and automatic control of the entire process. The drying oven is equipped with a high-temperature resistant centrifugal blower,During work, the hot air (adjusted internally through the air supply duct) set in the heating chamber of the drying oven is uniformly forced into the working chamber through a blower,After exchanging heat with the workpiece in the studio, the hot air flows back to the return air duct and is then sent to the heating chamber for heating by the blower,Hot air repeats itself in the drying oven,Make the temperature inside the drying oven meet the process requirements.
This product has the characteristics of high temperature control accuracy, easy operation, energy saving, high safety and reliability.Widely used in the spraying industry for mold PTFE spraying, mold preheating, epoxy casting curing and drying processes.

Working Principle: |
The air is blown into the left and right air ducts by a high air volume blower, and after heat exchange with the electric heating elements in the ducts, it is blown out from the lower air outlet of the left and right air ducts. After entering the working room and exchanging heat with the workpiece, it returns to the blower motor through the top return air plate, thus forming a continuous hot air cycle. Simultaneously using a porous regulating plate for air volume adjustment ensures good temperature uniformity within the workspace. Vertical air supply from bottom to top |
