Nanjing Huozao Machinery Technology Co., Ltd. is one of the leading manufacturers and suppliers of dual-fuel hot air circulating drying oven in China. With abundant experience, we are committed to providing high quality equipment made in China with competitive price. Welcome to wholesale customized dual-fuel hot air circulating drying oven from our factory.
Working Principle
Hot Air Circulation: Hot air is delivered into the oven chamber by a fan and evenly distributed through the air ducts, ensuring uniform heating of the materials.
Heating Method: The dual-powered (electric and steam) hot air circulating oven offers multiple heating methods for users to choose from, including steam heating and electric heating.
Circulation and Dehumidification: Most of the hot air returns to the fan inlet for continued circulation, while some humid air is discharged from the exhaust port, and fresh air is replenished through the air inlet.
