Two-Layer Single-Door High Vacuum Oven
Application: Suitable for baking lithium-ion battery electrodes, battery cells, and pre-injection batteries
1. Frame section
2. Inner chamber section
3. Vacuum pumping and nitrogen injection section
4. Electrical control section
5. External circulation section
6. Internal circulation section
7. Cooling system section (optional configuration)
Place the battery cells or electrode sheets into the oven, set the heating time, vacuum time, and nitrogen time. The system will automatically carry out heating and timed gas exchange based on the preset time parameters to complete the baking process
1. Heating – Includes external and internal heating systems:
U-shaped electric heating tubes with forced air circulation for fast temperature rise
2. Vacuum pumping:
Equipped with a vacuum pump, capable of reaching the set vacuum level within 5 minutes; an alarm is triggered if the set value is not reached
3. Nitrogen injection:
An alarm is triggered if nitrogen is not detected during automatic injection
4. Cooling:
Automatically stops when the temperature drops to the set value
l Internal chamber size: 700 mm (H) × 800 mm (W) × 1300 mm (D) (×2 chambers) (customizable upon request)
l External dimensions: 1870 mm (H) × 1500 mm (W) × 2000 mm (D)
l Equipment color: Off-white (customizable upon request)
1. Exterior material: A3 cold-rolled steel plate with baking paint treatment, color: off-white
2. Inner chamber material: 304# industrial brushed stainless steel plate, thickness: 5.0 mm
3. Door structure: Single-door, filled with aluminum silicate insulation cotton; pressure-sealed door (automatically sealed upon closing); exterior of the furnace door made of steel plate with paint treatment
4. Sealing ring: Molded silicone rubber O-ring, high-temperature and corrosion resistant
5. Vacuum and nitrogen ports and interface specifications: Ports located at the back; vacuum port: KF40; nitrogen gas inlet: φ12 mm gas pipe connector
6. Control system: PLC automatic control, HMI with touchscreen interface
The system includes:
l 1 high vacuum pump unit (customer-supplied)
l 1 auxiliary cooling system (customer-supplied)
l 1 high vacuum oven
Vacuum system provided by the supplier. A maximum of two chambers can be vacuumed simultaneously. Once the set vacuum level is reached, the branch valve will close automatically before the other chamber starts vacuuming.
l Ultimate pressure at pump inlet: ≤10 Pa (no-load condition)
l Single chamber vacuuming from atmospheric pressure to 20 Pa: ≤10 min (no-load)
l Vacuum leakage rate (cold no-load): After reaching ultimate vacuum and closing the valve, vacuum remains at ≤500 Pa within 24 hours
l Vacuum method: Shared vacuum pump for multiple chambers
l No-load ultimate vacuum: ≤20 Pa
l Practical vacuum varies with exhaust volume of the baked material
l Set vacuum levels:
High vacuum: 50–100 Pa (for efficient moisture removal)
Low vacuum: ≤2000 Pa (for nitrogen exchange threshold)
l System includes: Two-stage vacuum pump and pipeline
Vacuum pump: provided by customer or supplier
Vacuum pipeline: according to final confirmed drawings based on the location of the pump and oven
Short distances: stainless steel corrugated hoses provided by supplier
Long-distance piping: to be confirmed in advance with installation party designated
l Distance between ovens: approx. 600 mm
l Distance from oven to vacuum pump: <2000 mm
l Distance from oven to chiller: <3000 mm
l Cold air ducts mounted on oven top
l Vacuum pipelines use stainless steel flexible hoses
l Air ducts: 110 mm PVC pipes wrapped with insulation cotton for better thermal retention
l Connection: Pipes connect to oven cooling inlets
l Total cooling power: 4 KW
l Cooling temperature setting: 5–10°C
l Cooling time: 90–150 minutes to reach the set temperature
1. Vacuum level: Ultimate vacuum per chamber ≤1 Pa; no-load ≤20 Pa; full-load: 50–100 Pa; leakage within 24h ≤500 Pa
