Advantage
1)Keep a certain distance from the magnetron tube to ensure that the object is heated synchronously.
2)The top of the box is designed with an arched slope of 80~100mm, and the condensed water will slide down along the slope without dripping on the ashes.
3)The bottom is also formed into an arc shape, and the accumulated water is easy to leave.
4)The sewage outlet pipeline is hidden in the line of sight, and is accompanied by a tendency to avoid damage to the sewage pipeline from the upper and lower cargo.
5)The requirement of round corners in the microwave vacuum drying oven of our company can meet the requirement of no dead corners.

1. What is an Automated Microwave Vacuum Drying Oven and what does it do?
It is an industrial dryer that combines microwave heating with vacuum conditions to remove moisture quickly and gently from materials (chemicals, plastics, food). Vacuum lowers boiling point for efficient drying, while microwaves heat material volumetrically for faster, uniform drying.
2. What are the key specifications of model WBHX-4?
Model WBHX-4 has 4 kW microwave power, water evaporation capacity 3–4 kg/h, adjustable drying temperature RT–200°C, vacuum degree up to -0.05 MPa, drying chamber 600×600×500 mm, overall size W1200×D800×H1500 mm, and weight about 500 kg.
3. What power and motor ratings does the machine use?
The unit uses a 4 kW microwave generator for heating (WBHX-4). Mechanical components are driven by an industrial motor (configurable; some configurations use a 6 kW motor) — motor size depends on optional features. Exact motor rating is specified with your order.
4. What production capacities can this oven handle?
Typical drying capacity is 5–50 kg/h depending on material and moisture load; sterilizing capacity is up to 50 kg/h. Actual throughput depends on material properties, loading method and drying parameters.
5. Which materials and industries is it suitable for?
Designed for food, chemicals and plastics processing. Construction materials (SUS304 / SUS304L / SUS316 / SUS316L) support food-grade and corrosive environments. For flammable/explosive or highly reactive materials, consult manufacturer for safe use or special certifications.
6. How does vacuum level affect drying performance?
Operating under vacuum (up to -0.05 MPa) reduces the boiling point of water and solvents, accelerating evaporation at lower temperatures and protecting heat-sensitive materials while improving product quality and safety.
7. How is temperature and process control handled?
The oven features PLC-based controls allowing adjustment of drying temperature (RT–200°C), microwave power, vacuum level and timing. PLC provides repeatable program control for consistent batches.
8. What safety features are included?
Safety components include a certified pressure vessel construction, PLC monitoring, interlocks on door and service access, controlled microwave shielding, and engineered condensation/drainage design to avoid spills. Additional safety options can be provided per application.
9. How is condensation and drainage managed?
The chamber top is sloped and the bottom formed as an arc so condensed water flows away from product and into hidden sewage outlet piping. This design prevents dripping onto product and protects pipelines from cargo damage.
10. How easy is cleaning and avoiding contamination?
Round-corner internal design (no dead corners) and stainless-steel construction (SUS3xx options) facilitate thorough cleaning and sanitary operation, making it suitable for food applications with appropriate cleaning procedures.
11. Can the machine be customized?
Yes. Capacity, chamber size, materials (SUS304/304L/316/316L), control options, and evaporation capacity can be customized to meet process requirements. Discuss your application for a tailored specification.
12. Are there restrictions for drying flammable solvents or explosive dusts?
Special precautions are required. Drying flammable solvents or combustible dusts may need explosion-proof design, inerting systems or certification (e.g., ATEX). Contact the manufacturer with material safety data for an assessment and safe configuration.
13. What are the installation and utility requirements?
Typical requirements include appropriate electrical supply (per model), vacuum pump connections, ventilation for exhaust/condensate handling and a floor capable of supporting ~500 kg plus load. Exact utilities depend on model and options — manufacturer will provide installation specifications.
14. What maintenance and service are required?
Periodic checks include microwave generator (magnetron) inspection, vacuum pump maintenance, seals and gaskets, PLC/software updates, and cleaning of drains. Magnetron replacement and high-voltage servicing should be performed by qualified technicians. Service plans and spare parts are available from the supplier.
15. Do you offer testing, certification, training or warranty?
Most suppliers provide factory acceptance testing (FAT), optional certifications on request, operator training, and standard warranty terms. Specifics (warranty length, certifications) should be confirmed with the vendor before purchase.
