Regular cleaning of the drying oven not only helps to maintain the good performance of the equipment, but also extends its service life and ensures the accuracy of experiment or production results. The following is a detailed drying oven cleaning method for reference.

Preparation before cleaning

Power off: Ensure that the drying oven is powered off and unplug the power to prevent accidents during cleaning.
Cooling: Wait until the inside of the oven is completely cooled. Avoid cleaning at high temperature to avoid burns.
Tools: Prepare the necessary cleaning tools, such as buckets, brushes, soft cloth, white silk cloth, etc.
Detergent: Choose the right detergent according to the material and dirt level of the drying oven. A neutral detergent is usually used, with an aqueous solution of 0.5%.

Cleaning procedure

Remove the remaining material: First remove the remaining material inside the drying box and on the tray and bracket with a brush, promptly put it into a dust-free container or plastic bag, closed in the designated place, and remove it out of the operation area in time after the end of the work.
Rinse: Rinse the inside of the primary drying oven and the trays and brackets with drinking water to initially remove dust and dirt.
Washing: Wash the inside of the drying box and the tray and bracket carefully with a neutral detergent solution to ensure that every corner is cleaned.
Rinse again: Rinse the tray and bracket thoroughly with drinking water until it is clean and ensure that no detergent remains.
Drying: Put the reverse side of the tray in the bracket, close the drying oven door, and steam for 3-5 minutes for drying.

Cleaning effect evaluation

After cleaning, wipe the surface of the tray, bracket and drying oven with white silk cloth to check whether there is no residue of dirt. If there is no obvious stain on the silk cloth, it means that it is clean.

Matters needing attention

Avoid using corrosive cleaning agents: Do not use corrosive cleaning agents to avoid damaging the surface and internal components of the drying oven.
Keep dry: Ensure that the drying oven is placed in a dry and ventilated environment to avoid damage to the equipment caused by damp and dust.
Clean the filter regularly: the air inlet of the drying box is provided with a filter screen, which needs to be cleaned regularly to ensure smooth air circulation.
Check the sealing strip: Regularly check whether the sealing strip of the filament dryer oven is intact. If it is damaged or aging, it should be replaced in time to ensure the sealing performance of the box.

Care and maintenance

Regular inspection: Periodically check whether key components such as heating elements, fans, and temperature sensors are in good condition. If abnormal, replace or maintain them in time.
Environmental control: Avoid direct sunlight and high temperature environment, so as not to affect the temperature control accuracy and service life of the drying oven.
Regular calibration: In order to ensure the temperature control accuracy of the drying oven, it is necessary to regularly calibrate the equipment, which can be operated according to the method in the equipment manual, or contact professionals for calibration.

Through the above cleaning methods and maintenance measures, the normal operation and long-term use of the drying oven can be ensured, providing a stable and reliable guarantee for experiment and production.
