Food safety, disinfestation, insect sanitation - Industrial microwave and radio frequency systems | SAIREM Technologies

Microwave and radio frequency: a clean disinfestation method

Microwave and radio frequency technologies provide an effective thermal solution for insect control in food ingredients. As food safety standards tighten and chemical treatments are increasingly restricted, manufacturers are looking for reliable methods to eliminate insect contamination while preserving product quality.

By generating rapid, volumetric heating directly within the product, SAIREM systems efficiently destroy insects at all stages of development — eggs, larvae, and adults — without the use of chemicals. This approach ensures consistent results across a wide range of products, including low-moisture ingredients, while maintaining their sensory and nutritional properties.

Key advantages of microwave  and radio frequency decontamination

Fast, in-depth disinfestation

 
Volumetric heating destroys insects and larvae inside the product within seconds or minutes, much faster than hot-air or fumigation processes.

Chemical-free, residue-free

 
Eliminates pests without phosphine, methyl bromide, or synthetic fumigants. No residues, no withdrawal period, fully aligned with clean-label requirements.

Preserves food quality

 
Controlled heating prevents over-drying or roasting, maintaining the natural color, texture, and nutritional value of grains and seeds.

Uniform, repeatable results

 
Microwave and radio frequency penetrate dense products, ensuring complete disinfestation, even in bulk materials with uneven density.

Packaging compatibility

Can treat products in bulk bags, boxes, or continuous-flow conveyors without damaging packaging.

Energy-efficient and compact systems

Electric, high-efficiency units with up to 79% of energy transferred to the product, designed for easy integration into industrial lines.

No downtime, no long fumigation

Removes the need for storage rooms and multi-day treatments, improving logistics and supporting just-in-time production.

Supports export compliance

Helps meet international phytosanitary requirements and reduces the risk of infestation during transport.

Applications for insect control in food products

Microwave disinfestation is widely used for insect control in food ingredients such as grains, flours, nuts, and seeds. Below are typical products that benefit from this process. For specific applications, feel free to contact us.

Beans disinfestation

Microwave treatment instantly eliminates insect eggs and larvae present inside beans without affecting their hydration level or appearance.

  • Kills all insect life stages inside dry beans
  • No chemical residues
  • Prevents reinfestation during storage
  • Preserves color and structural integrity

Cereals and grains disinfestation

Ideal for wheat, barley, oats, corn, and multi-source cereal ingredients. Volumetric heating ensures a uniform temperature rise at the core for reliable insect elimination.

  • Fast treatment for high-throughput cereal lines
  • Maintains milling and baking functionality
  • Reduces losses linked to fumigation or long storage times
  • Compliant with export phytosanitary requirements

Rice disinfestation

Microwaves effectively eliminate larvae (e.g., rice weevil), which often hide deep inside kernels where chemicals cannot reach.

  • Effective against internal and external pests
  • Avoids fissuring or cracking of rice grains
  • Suitable for white, brown, and parboiled rice
  • Clean-label, energy-efficient process

Nuts & seeds disinfestation

Ideal for almonds, pistachios, hazelnuts, sunflower seeds, chia, sesame, flaxseed, and similar products.

  • Protects premium quality nuts
  • Prevents rancidity due to long thermal exposure
  • No flavour alteration or oil migration
  • Compatible with organic products

Here’s a questions-and-answers section about our industrial disinfestation solutions.

Yes. Microwave destroys insects at all life stages — eggs, larvae, pupae, and adults — ensuring full disinfestation.

Yes. Microwave disinfestation is a chemical-free alternative that eliminates residues, reduces treatment time from days to minutes, and helps meet export phytosanitary regulations.

No. SAIREM systems ensure precise temperature control, preventing cracking, roasting, or degradation of product quality.

Yes. Microwave and radio frequency disinfestation systems can treat food products directly in their packaging, including bags, boxes, paper, and certain plastic materials, depending on thickness and composition. This allows effective insect control while maintaining product integrity and simplifying industrial processing.

Yes. Microwave disinfestation is a chemical-free process that eliminates the need for fumigants such as phosphine or methyl bromide. It also reduces energy consumption compared to conventional thermal treatments, making it a more sustainable solution for food safety and insect control.
