Dryer Features

Microwave dryer features

  • Drastic Reduction in Drying Time: By directly heating water molecules, drying time can be significantly reduced by 25% to 90%.

  • Reduced Operational Costs: Lower energy consumption compared to conventional methods, combined with a compact design and fast cycle times, leads to overall cost savings.

  • Ultra-Low Moisture Content: Capable of drying materials down to a moisture content of 1% or less, which is extremely difficult to achieve with traditional drying methods.

  • Prevention of Over-Drying: Because it does not rely on traditional heat transfer (conduction/convection), the heating speed is exceptionally fast. This minimizes surface hardening, carbonization, or cracking caused by prolonged heat exposure.

  • Material Integrity: Drying occurs at relatively low temperatures (approx. 70~80°C based on exhaust temperature), minimizing damage to the raw materials.

  • Eco-Friendly Process: Since no fossil fuels are used, the process is free from combustion exhaust gases, allowing for the minimization of secondary environmental control equipment.

Primary Applications of Microwave Dryers

  • Food Industry: Agricultural products, grains and nuts, tea leaves and medicinal herbs, sterilization, and thawing.등

  • Chemical & Advanced Materials: Secondary battery materials (cathode and anode raw materials), ceramics and catalysts, high-purity ceramic raw materials, graphene, and nano-materials.조

  • Pharmaceuticals & Cosmetics: Raw powders for tablets and capsules, natural extract powders, mask pack sheets, etc.

  • Textiles & Wood: Drying of thick timber/lumber and fabric drying.

  • Waste Management: Volume reduction of sewage sludge and industrial waste.

Drying System Selection

  • Various configurations—including continuous (conveyor), batch, and vertical types—can be adopted, allowing for selective application tailored to the specific requirements of the site.

  • Continuous (conveyor)

  • Batch type

  • Vertical type

Microwave Power Selection

  • Pilot Testing: Conduct pilot drying tests on target materials as required to verify performance.

  • Heat Requirement Calculation: Calculate the required heat capacity based on the specific physical properties and moisture content of the target material.

  • System Calibration: Select the appropriate frequency and calculate the required microwave power based on the chosen drying method (Continuous, Batch, or Vertical).

  • Energy Integration: Review the application of waste/idle energy (such as steam or other thermal sources) from the existing process as a supplementary heat source to maximize efficiency.

  • Example of calculating required heat by material balance

  • Example of P&ID and PFD creation linked to pre- and post-equipment

Microwave Simulation

  • Uniform Energy Distribution: Simulation of microwave dryer modules to ensure a uniform electromagnetic field distribution across the target area.

  • Leakage Shielding: Simulation of shielding modules designed to perfectly block microwave leakage to the exterior of the device for operator safety.

  • Heating Method Geometry: Geometric simulation of the system structure optimized for specific heating methods (conduction, convection, or direct radiation).

  • Transmission Optimization: Simulation of microwave transmission lines and antennas to minimize power attenuation (loss) during energy delivery.
