Air drying ovens are equipment specifically designed for drying thermosensitive, easily decomposable, and oxidizable substances. Currently, air drying ovens have been widely applied in biochemical, pharmaceutical, healthcare, agricultural research, environmental protection, and other research and application fields. In recent years, the market scale of China’s air drying oven industry has continued to expand, and with the rapid development of pharmaceutical, environmental protection, and medical industries, its future growth potential remains significant.
Current Status of Domestic Air Drying Oven Industry
At present, domestic air drying ovens are becoming increasingly diverse, with market share gradually rising. However, compared to foreign counterparts, domestic drying equipment still lags in product performance, automation levels, and service life.
As industry requirements for equipment efficiency and reliability continue to escalate, users are placing greater emphasis on drying efficiency and service life—two critical factors that directly impact production stability and economic benefits for enterprises.
Key Factors for Improving Drying Efficiency
It is reported that many users encounter incomplete drying of materials during operation. Excluding equipment malfunctions, standardized operational practices are key to enhancing drying efficiency. Users are advised to focus on the following:
- Equipment Inspection: Conduct comprehensive checks on circuits, control instruments, and other components before startup.
- Proper Material Arrangement: Distribute materials evenly with sufficient spacing to facilitate hot air circulation and improve drying uniformity and efficiency.
- Temperature Control: Set appropriate temperatures and activate the air blower system to ensure even heat distribution.
- Staged Heating: After temperature stabilization, turn off one set of heating elements to avoid overheating, enhance temperature control accuracy, and reduce energy consumption.
Recommendations for Extending Equipment Service Life
The technicians of the drying equipment manufacturer suggest that in order to extend the service life of the air drying box, users can take the following measures:
First, the air drying box should be placed in a flat place indoors. This drying box is a non-explosion-proof drying box and contains flammable and volatile items. Do not put flammable and explosive items in the drying box to avoid accidents.
Second, after the power is turned on, you can turn on the two sets of heating switches, and then press the button of the control instrument to set it to the temperature required by the user. The indicator light is on, and the blower switch is turned on at the same time to make the blower work.
Third, when the temperature is constant, one set of heating switches can be turned off, leaving only one set of electric heaters to work, so as to avoid excessive power and affect the sensitivity of constant temperature.
Fourth, before powering on, check the electrical performance of the air drying box, and pay attention to whether there is a circuit break or leakage. An iron shell knife switch should be installed in the power supply line dedicated to the box, and the box should be grounded.
Fifth, do not remove the side door, interfere with or change the line at will. Only when the box fails, the side door can be removed and checked according to the line. If a major failure occurs, contact the manufacturer.
In addition, some users reported that the heating wire of the air drying box exposed to the air is easy to oxidize due to the high temperature and long-term heating, which affects the life. In response to this problem, some experts said that the heater can use a coil-type electric heating tube to reduce the oxidation rate and increase the life. Manufacturers should also design different types of heating control systems according to the user’s production process conditions to ensure its efficiency.
Industry Development Recommendations and Trends
Currently, China’s air drying oven industry faces significant market demand and promising growth potential. However, scaling the market and advancing the industry require progressive improvements in environmental policies and overall industry standards. Therefore, while domestic manufacturers recognize market opportunities, they must also align with industry trends, upgrade equipment capabilities, and accelerate the development of the air drying oven sector.
