HOW IT WORKS

The Mildtech Process

Our solid-state microwave and vacuum systems combine precise energy delivery with controlled pressure and temperature to enable advanced drying, heating and thermal processing.

01

Solid-State Microwave Energy

Precisely controlled microwave energy is generated using solid-state semiconductor technology.
02

Volumetric Heating

Microwave energy interacts directly with the material, generating heat throughout its volume rather than relying solely on heat transfer from the surface.

03

Vacuum-Assisted Moisture Removal

Reduced pressure lowers the boiling point of water, allowing moisture to be removed at lower temperatures.
04

Real-Time Process Control

Sensors continuously monitor key process conditions, allowing the system to respond to temperature and vacuum throughout processing.

05

Flexible Process Conditions

Microwave power, frequency, vacuum and temperature limits can be configured to suit the material and processing objective.

06

Controlled Finished Product

Precise control throughout processing helps achieve the required final product characteristics consistently and repeatably.

MICROWAVE + VACUUM

Lower Temperatures. Greater Process Control.

Applying vacuum reduces the boiling point of water, allowing moisture to be removed at lower product temperatures. Combined with precisely controlled microwave energy, this enables rapid and highly controllable processing while reducing unnecessary thermal exposure.

Conventional Heating
(surface to core)

Microwave Heating (volumetric)

VOLUMETRIC MICROWAVE HEATING

Energy Delivered Throughout the Material

Unlike conventional heating which relies on thermal conduction from the surface to the core, microwave energy penetrates the material to deliver heat volumetrically. This results in faster, more uniform heating and improved process efficiency.

PRECISION PROCESS CONTROL

Control the Process, Not Just the Power

Mildtech systems provide precise control over the key parameters that influence microwave processing. Microwave power, frequency, vacuum, temperature and process time can be controlled through programmable recipes, helping deliver consistent and repeatable processing conditions across different products and applications.

Microwave Power

Precisely control microwave energy input throughout each stage of the process.

Frequency

Control and sweep operating frequency to optimise energy coupling for different products and materials.

Vacuum Level

Set and control processing pressure according to the requirements of the product and application.

Temperature

Monitor product temperature and apply defined temperature limits throughout processing.

Time & Recipes

Create and store repeatable processing recipes incorporating power, frequency, vacuum, temperature and time.

Process Endpoints

Use process data such as temperature and moisture measurements to help determine when processing is complete.

FLEXIBLE FREQUENCY Ranges

Multiple Microwave Frequency Ranges

Mildtech develops solid-state microwave systems across multiple frequency ranges, allowing the technology to be configured according to system scale, product characteristics and processing requirements.

2400–2500MHz

Suitable for compact systems, research applications and processes requiring precise, highly controllable microwave energy delivery.

900–930MHz

Suitable for larger-scale systems and applications requiring greater microwave penetration through larger product volumes.

425–475MHz

Designed for larger processing volumes and applications where deeper penetration and more uniform energy distribution through bulk material are important.

The optimum operating frequency depends on the material, product geometry, processing objective and system scale.

DRYING, HEATING & THERMAL PROCESSING

More Than Drying

Mildtech’s solid-state microwave technology can be configured for a wide range of processing applications, from low-temperature vacuum drying to precise heating and controlled thermal processing. Vacuum can be applied where lower-temperature moisture removal is required, while atmospheric processing enables higher-temperature heating applications.

Low-Temperature Drying

Vacuum-assisted microwave drying for heat-sensitive products and materials where controlled moisture removal at reduced temperatures is required.

Controlled Heating

Precise microwave heating with controllable power, frequency and temperature, with or without vacuum depending on the application.

Thermal Processing

Controlled microwave processing for applications requiring defined temperature profiles and targeted thermal treatment.

Process Development

Development and optimisation of new microwave processes for specialist products, materials and production requirements.
