DZF Vacuum Drying Oven
Working Principle
Different from conventional forced air drying ovens, this vacuum drying oven creates a negative-pressure enclosed chamber. Under vacuum conditions, the boiling point of moisture inside test samples is significantly reduced, enabling rapid dehydration at low temperatures without high-temperature baking. The oxygen-deficient vacuum environment effectively prevents oxidation, discoloration and thermal decomposition of heat-sensitive substances, preserving the original physical and chemical properties of test materials. The built-in PID temperature control system maintains constant temperature accurately during the whole drying cycle, ensuring uniform moisture removal across all samples.
Premium Material Configuration
● Outer cabinet: Thick cold-rolled steel sheet with anti-rust electrostatic spraying, scratch-resistant and long service life;
● Inner chamber: Integrally formed 304 stainless steel, arc seamless design without dead corners, corrosion-resistant and easy to wipe clean;
● Door seal: High-elastic silicone rubber sealing ring, excellent air tightness to sustain stable vacuum for long hours;
● Observation window: Double-layer tempered explosion-proof glass, safe for real-time sample inspection without breaking vacuum;
● Internal racks: Detachable stainless steel trays, support layered placement of different specimens.
Wide Application Scopes

2. Independent vacuum adjustment knob and real-time vacuum pressure gauge for convenient vacuum extraction and nitrogen filling;
3. Automatic over-temperature protection and power-off memory function to avoid sample damage caused by abnormal conditions;
4. Compact bench-top structure saves laboratory counter space, simple operation with minimal training required;
5. Reserved USB data export port to store drying temperature curves and experimental data for test report filing.
FAQ
Q1: What Kinds Of Samples Are Not Suitable For This Vacuum Drying Oven?
A1: Samples that produce volatile flammable, explosive or corrosive gas under heating are prohibited, as such substances may cause chamber corrosion or safety hazards in vacuum environment.
Q2: Why Is Vacuum Drying Better Than Ordinary Blast Drying For Heat-Sensitive Materials?
A2: Vacuum lowers water boiling point to realize low-temperature dehydration. Meanwhile, the low-oxygen environment stops sample oxidation and deterioration, which cannot be achieved by hot air circulation drying at normal atmospheric pressure.
Q3: Can This Vacuum Drying Oven Be Connected To A Nitrogen Tank For Inert Gas Protection?
A3: Yes. The machine reserves an inert gas inlet port. You can connect a nitrogen cylinder to fill the chamber and fully isolate oxygen when processing highly oxidizable raw materials.
Q4: What Standard Volume Sizes Do You Provide For The DZF Series?
A4: We supply three mainstream models: 20L (DZF-6020), 50L (DZF-6050) and 90L (DZF-6090). Customized large vertical vacuum drying ovens are available upon customer request.
Q5: How To Maintain Stable Vacuum Tightness Of The Equipment Long-Term?
A5: Regularly check the silicone rubber door seal for aging or cracks; clean foreign matters on the door frame before closing each time; avoid scratching the sealing ring with sharp tools to guarantee airtight performance.
