Nanjing Huozao Machinery Technology Co., Ltd. is one of the leading manufacturers and suppliers of steam 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 steam drying oven from our factory.
Working Principle
The working principle of the steam drying oven is based on a combination of "forced hot air circulation + steam heat exchange":
Steam Input: An external steam pipe introduces saturated steam from a boiler into the finned radiator inside the equipment.
Heat Exchange: Steam flows within the radiator tubes, transferring heat through the finned tube walls to the cold air flowing outside. The steam itself condenses into water, which is discharged through a steam trap.
Hot Air Circulation: A high-temperature resistant axial flow fan delivers the heated air from the radiator into the air duct. After being evenly distributed by an adjustable air distributor, the air flows horizontally or vertically over the materials placed on the drying trays, undergoing heat exchange and removing moisture from the materials.
Circulation and Dehumidification: Most of the hot air returns to the fan inlet for continued circulation, while some humid hot air is discharged from the dehumidification outlet. Simultaneously, fresh air is supplied from the air inlet to maintain a suitable humidity level inside the steam drying oven.
Features
Low operating costs: Steam heat energy costs are far lower than electricity prices, making it suitable for continuous mass production; existing enterprise steam networks can be directly connected, resulting in extremely low marginal costs.
Temperature control capability: Standard temperature range 50-140℃ (maximum 150℃), with accuracy reaching ±1-2℃ when using a PID/PLC system; however, it is not suitable for high-temperature processes above 160℃.
Safety and compliance: No open flames or electric sparks, inherently safe; the inner chamber uses a stainless steel rounded corner design and is equipped with an H13 high-efficiency filter, eliminating dead corners and facilitating easy cleaning, fully complying with GMP verification requirements.
High efficiency and uniformity: Fully enclosed circulation achieves a thermal efficiency of 35-70%; forced circulation air combined with a distribution plate controls the temperature difference within the chamber to within ±2℃.
