Compared with conventional ovens, it has advantages of stable performance, high vacuum level, short baking time, excellent dewatering and drying effect, and good pressure retention. It is combined with a dedicated high vacuum unit and cooling system to form an independent baking system, replacing conventional traditional ovens. IV. Working Principle Each machine can operate in continuous cycles; the basic process: open the door, place the cells or electrode sheets into the oven, then set the heating time, vacuum time, and nitrogen time. The system will automatically complete heating and timed gas exchange according to the preset time parameters, completing the baking process.   V. Product Features High Vacuum Design The internal chamber is made using pressure vessel standard welding process, with high vacuum retention, long durability, and no deformation. Stable Temperature Uniformity Temperature uniformity reaches ±3℃ under constant temperature. Optimized Space Design The internal chamber size can be customized according to the customer’s battery size, improving space utilization efficiency. Precise Temperature Control Temperature is controlled using silicon-controlled rectifier (SSR) + PID mode, with low thermal inertia and good control effect. Heating Method Hot air circulates both inside and outside the chamber, maintaining consistent internal and external chamber temperatures. Heat radiation and heat conduction ensure chamber temperature uniformity. During cooling, heating tubes are shut off, and internal heat is carried away by air circulation, accelerating cooling speed. Sixfold Safety Protection Ensures operational safety and product reliability. Automated Program Control PLC program controls heating, vacuuming, and nitrogen injection. Manual/automatic operation modes can be switched. Automatic timed heating is completed by simply setting heating time, vacuum time, and nitrogen time. The system will automatically perform baking and gas exchange. Internal Airflow Structure Uses magnetofluid circulation with good sealing and high temperature resistance.   VI.

L. Touchscreen display, automatic circulation and control, automatically returns to vacuum holding at the end; digital display of safety temperature. M. Equipped with multi-level over-temperature protection, effectively prevents temperature control failure and enhances accuracy of protection. N. Control panel adopts centralized touchscreen operation, convenient and reliable control. Program controller adopts PLC control, stable and reliable operation. O. The two-barrel oven is independently controlled, can set total baking time, cycle time, vacuum time, drying time separately. After setting parameters, pressing the auto button will enter the automatic baking program. When the baking time is reached, the system will automatically shut down. If the temperature exceeds the safety limit, it will automatically alarm, the red indicator light turns on, heating stops, and the alarm information is displayed on the screen. P. During normal operation, fault warnings and causes can be displayed on the screen in real-time. 4.
