INDUSTRIAL MICROWAVE FEASIBILITY TESTING

AMT designs and carries out focused feasibility studies and laboratory trials to investigate how materials and processes respond to microwave energy, identify useful operating conditions and generate evidence for the next development decision.

FOCUSED TESTING, BUILT AROUND THE PROCESS

A useful microwave trial starts with the technical question, not with a standard test procedure.

AMT considers the material, existing process, desired outcome, previous work and practical constraints to determine what should be investigated and how to test it meaningfully.

The work can be tightly scoped around a single question or form the first stage of a larger development program.

WHAT CAN A LAB TRIAL REVEAL?

A focused trial can answer very different questions depending on the material and process. Typical areas include:

MATERIAL RESPONSE:

  • Microwave absorption and coupling

  • Heating rate and temperature behaviour

  • Heating uniformity and penetration

  • Selective heating between different materials or phases

PROCESS EFFECTS:

  • Changes in reaction rate or process behaviour

  • Physical or chemical transformations

  • Effects on product or material characteristics

  • Promising temperatures, times and operating conditions

ENERGY & THROUGHPUT:

  • Energy required to achieve the target temperature or process change

  • Estimated microwave power required for the desired throughput

  • Heating time and residence-time requirements

CONFIGURATION & DEVELOPMENT:

  • Appropriate microwave power and frequency

  • Applicator and field behaviour

  • Impedance matching and operating configuration

  • Factors likely to matter when moving toward larger-scale processing

HOW AMT APPROACHES FEASIBILITY WORK

Not every project needs the same investigation. AMT starts with the process requirements, identifies the important unknowns and uses calculations, simulation and practical testing where they will provide useful evidence.


01 - PROCESS & ENERGY DUTY

Establish the material, starting and target conditions, throughput and required process change.

First-pass mass and energy calculations can then estimate the heating duty, residence time and microwave power range likely to be required.

02 - DESIGN THE INVESTIGATION

Identify what cannot be answered from calculations alone and determine the most useful way to investigate it.

This may involve desktop engineering, simulation, laboratory testing (or a combination) with the test configuration built around the process.

03 - TEST & MEASURE

Carry out controlled trials to determine how the material or process actually responds.

Depending on the application, this may include heating rate, absorbed energy, temperature behaviour, uniformity, selective heating, reaction effects, material changes and operating stability.

04 - INTERPRET & DEVELOP

Compare the measured behaviour with the original energy, throughput and process requirements.

Use the evidence to identify promising operating conditions, remaining uncertainties and the most useful next step — further testing, process development, higher-power work or scale-up.

PRACTICAL DEVELOPMENT CAPABILITY

AMT maintains an industrial microwave development facility in Wollongong with the equipment and flexibility needed to investigate processes at a meaningful engineering level.

Microwave generators, impedance-matching equipment, network analysis, simulation capability, instrumentation, existing applicators, specialised process hardware and in-house fabrication can be brought together as required for each investigation.

Many focused laboratory trials can be completed within a few days. A typical program may involve around one day of setup and two days of testing, followed by results analysis or external laboratory analysis of the processed material.

FROM TRIAL TO DEVELOPMENT

A feasibility trial does not need to produce a finished process. Its purpose is to generate enough useful evidence to decide what should happen next.

Where results are promising, AMT can continue into process and applicator development, higher-power testing, pilot-scale work and industrial scale-up.

Where results are less clear, the next step may be further targeted testing, a revised configuration or a different process approach.
