DZF-6050 Vacuum Lab Oven With Optional Vacuum Pump

53L 250°C DZF-6050 Vacuum Lab Oven With Optional Vacuum Pump And 30 Segment Programmable Temperature Controller 

Introduction

The DZF-6050 Vacuum Drying Oven is a laboratory and pilot-scale thermal processing unit designed for moisture removal, solvent evaporation, and heat treatment under reduced-pressure conditions. In lithium-ion battery manufacturing, vacuum drying is a critical step for ensuring low moisture content in electrode materials, separators, and assembled cells before electrolyte filling or sealing.

Compared with conventional hot-air ovens, vacuum drying allows materials to be heated at lower temperatures while maintaining high drying efficiency, which helps prevent oxidation, binder degradation, and structural damage to sensitive battery components.

The DZF-6050 model is widely used in battery research laboratories, university research centers, pilot production lines, and small-scale industrial environments where stable temperature control and reliable vacuum performance are required.

Technical Specifications

Customization Options

The vacuum drying oven can be configured according to different battery laboratory or production requirements. Optional customization includes chamber size, heating power, vacuum interface type, additional shelves, programmable controller, and different voltage standards.

For battery R&D laboratories, compact versions with precise temperature control are commonly used, while pilot production lines may require larger chambers or multiple ovens for parallel processing. Automation interfaces and external vacuum system integration are also available when the oven needs to be connected to a glove box system or dry room environment.

Working Principle and Drying Mechanism

Vacuum drying is based on the principle that the boiling point of liquids decreases as pressure decreases. When the chamber pressure is reduced, residual water, NMP solvent, or other volatile components inside the material can evaporate at a lower temperature, allowing safe drying of heat-sensitive materials.

During operation, the vacuum pump removes air from the chamber to create a low-pressure environment. The heating system raises the chamber temperature to a controlled setpoint, and the temperature controller maintains uniform thermal distribution inside the stainless-steel chamber. Under vacuum conditions, moisture and solvent molecules escape more easily from the material surface and internal pores, resulting in faster and more uniform drying.

This mechanism is especially important in lithium battery production, where trace moisture can react with electrolyte salts such as LiPF₆ and generate HF, which may damage electrodes and reduce cell lifetime.

Application in Lithium-Ion Battery Manufacturing

The DZF-6050 vacuum drying oven is commonly used in the following battery manufacturing processes:

● Drying of cathode and anode powders (LFP, NMC, graphite, silicon-based materials)
● Drying of electrode sheets after coating and calendaring
● Vacuum drying of separators before cell assembly
● Drying of pouch cells, cylindrical cells, and prismatic cells before electrolyte filling
● Removal of residual solvent (such as NMP) in laboratory and pilot production

Because the drying process takes place under vacuum, the risk of oxidation, contamination, or dust deposition is significantly reduced, which is essential for high-performance lithium-ion battery production.

Engineering Features

● Stable vacuum environment for low-temperature drying of sensitive materials
● High-precision temperature controller for uniform thermal distribution
● Stainless steel inner chamber suitable for battery materials processing
● Double-layer glass door for safe observation during operation

Integration into Battery Production Line

In lithium-ion battery manufacturing, the vacuum drying oven is typically installed before electrolyte filling or final sealing. In laboratory lines, the oven is often used together with slurry mixers, coating machines, rolling presses, and glove boxes to ensure low-moisture processing conditions.

In pilot and small-scale production environments, the oven can be connected with vacuum pumps, dry rooms, or inert gas systems to create a controlled atmosphere suitable for electrode and cell drying. The DZF-6050 model is suitable for laboratory-scale and pilot-scale production of pouch, cylindrical, and prismatic lithium-ion cells.
