Microwave and Radio frequency technology

Innovative Microwave and Radio frequency technology

Microwave and Radio Frequency technologies are suited to improve thermal processes such as tempering as defrosting, sanitizing, cooking, heating, pasteurization, drying. These two technologies are complementary and they both have their advantages depending on the products to be treated. We advise you which technology is most suitable for your product or process, as we master both technologies.

Microwave and Radio frequency for food industry

All food industries have different requirements and products, so everyone need a different solution. The technologies are developed for the tempering of various products: Microwaves are perfectly adapted to temper all kinds of meat: beef, pork, poultry, also with fat and bones. In contrast to that Radio Frequency is mainly suitable for standard fish blocks such as cod fish, salmon and so on.

What is Microwave and Radio frequency technology?

Microwave and Radio frequency are heating technologies based on the dissipation of electromagnetic energy within the targeted product. The heating process is generated by the quick polarity reversal of the electromagnetic field which creates vibration and rotation of the polarized molecules inside the material. This is made possible thanks to the dielectric loss properties of materials. This phenomenon is induced by the quick polarity reversal of the electromagnetic field (a million times per second). As water molecules are highly polarized, Microwave and Radio frequency technologies are very effective at heating up wet materials. Heat generation is almost instantaneous and allows for a perfectly controlled process thanks to rapid, uniform heating. Moreover, almost all the energy is transferred to the treated product, drastically reducing energy losses.

Where can Microwave and Radio frequency be integrated?

Microwave and Radio frequency can be used in all food industries, which are processing frozen products in Agriculture and food sector. Depending on the requirements the Microwave or Radio frequency can be used for butcheries, butchers, bakeries, dairies and other companies. Products like meat, fruit, seafood, vegetables, fish or butter can be quickly and efficiently tempered while maintaining the organoleptic properties.
