Petfood processing 4.0: Microwave solutions for efficiency, safety and quality

The challenges of modern petfood processing

The global petfood market is booming, driven by demand for premium quality products as well as rising safety and sustainability standards. This rapid growth creates significant technological challenges for manufacturers seeking to improve productivity while preserving product quality.

Conventional technologies—such as tempering rooms, steam or hot-air pasteurization tunnels, and traditional drying systems—remain widely used across the industry. However, they present several limitations.

For tempering, frozen meat blocks stored at −18 °C often require several days in tempering rooms before processing. This approach occupies valuable cold storage space, increases microbial risks, and slows down production cycles.

For pasteurization and sanitization, hot air or steam treatments may alter the nutritional profile, texture, or palatability of petfood products, while also struggling to ensure uniform treatment throughout the product.

Similarly, conventional drying methods are typically slow and energy-intensive, often leading to uneven moisture distribution and potential loss of sensitive nutrients.

As manufacturers seek more efficient, safe, and sustainable solutions, microwave and radiofrequency technologies are emerging as powerful alternatives for modern petfood processing.

Why choose microwave innovation for petfood processing?

Microwave and radiofrequency processing technologies provide a new level of performance and flexibility for petfood manufacturers.

Key advantages include:

Instant volumetric heating
Uniform energy transfer heats the product throughout its entire volume.

Faster processing
Treatment times can be reduced from days to minutes.

Preservation of food quality
Proteins, nutrients, texture, and palatability remain intact.

Clean-label processing
No additives, chemicals, or ionizing radiation are required.

Efficiency and cost savings
Up to 80% of the energy is absorbed directly by the product. No loss of weight during defrosting (no driploss).

High flexibility
Suitable for processing meat, kibbles, treats, cereals, vegetables, insects, and alternative proteins.

SAIREM microwave and radiofrequency applications for petfood

1. Tempering of meat, poultry, fish and vegetables

SAIREM microwave systems allow frozen products stored at −18 °C to be tempered to −4 °C / −2 °C in less than 10 minutes.

Key benefits include:

  • Processing times reduced from several days to minutes

  • No drip loss and no hot spots, resulting in direct bottom-line impact and short payback

  • Preservation of texture, proteins, and flavor

  • Greater flexibility in production scheduling

2. Pasteurization of wet petfood (pâtés, sauces, treats)

Microwave pasteurization tunnels can raise product temperature rapidly and uniformly, for example from 25 °C to 75 °C in under two minutes.

Advantages include:

  • Microbial reduction of 3–5 log CFU

  • Shelf life extension without preservatives

  • Preservation of palatability and nutritional value

3. Drying of ingredients (insects, cereals, vegetables)

Microwave drying technologies provide fast and homogeneous moisture reduction.

Main advantages:

  • Residual moisture below 10% achieved rapidly

  • Efficient even for low-moisture ingredients

  • In-line microbial decontamination

  • Significant energy savings compared to hot-air drying

4. Sanitization of raw materials (cereals, nuts, meat meals)

Microwave treatment provides fast and reliable microbial reduction for sensitive ingredients.

Benefits include:

  • Elimination of bacteria and molds in minutes

  • Clean-label safety without chemicals

  • Preservation of proteins and nutritional integrity

  • Easy integration into industrial ingredient processing lines

The future of petfood processing

The petfood industry is evolving rapidly, driven by premiumization, the humanization of pets, and increasing regulatory and sustainability pressures. Pet owners expect safer, more natural, and nutritionally balanced products, while manufacturers must manage rising energy costs, raw-material volatility, and labor constraints.

At the same time, the emergence of novel protein sources such as insect-based or plant-based ingredients introduces new processing challenges.

SAIREM’s microwave and radiofrequency solutions directly address these industry transformations. By reducing processing times from days to minutes, ensuring microbiological safety without preservatives, and preserving nutritional value and palatability, these technologies provide a powerful tool for modern petfood manufacturers.

Their flexibility also makes them ideally suited for processing next-generation ingredients, including cereals, insects, and alternative proteins.

In a market where efficiency, product quality, and sustainability are key competitive factors, microwave and radiofrequency processing technologies are becoming a strategic enabler for the future of petfood production.
