Microwave technology, RF & DC
Radiofrequency processing (RF) is a technology based on dielectric heating, where the product is heated volumetrically and not from the outside in as in traditional treatments. This technology has high potential in other processes such as: in the preservation of fruit and vegetables, deworming of insects in cereals, pasteurization of dairy products and other beverages such as juices, cooking of sausages and dehydration of products after baking, such as example cookies..
Microwave and Radio Frequency heating are thermal processing technologies based on the dissipation of electromagnetic energy within the target product. These technologies have unique and unmatched properties when it comes to heating and drying.
We respond to your demands quickly and competitively, we adapt to your projects, we provide you with specialized machinery for your industry. Above all of this, we stick to top-notch production quality.

Advantages of using Microwave and Radio Frequency technology:
- Homogeneous heating:
Microwaves and radio frequency heat the entire mass of the product directly and homogeneously, which is called “volumetric heating.”
Thanks to these properties, RF and microwave technology offers fast and reproducible results when used within industrial drying or food processing systems.
Fast and even heating:
Microwaves and radio frequency have the ability to heat thanks to the dielectric loss properties of materials. This phenomenon is due to the vibration and rotation of the polarized molecules inside the material, induced by the rapid reversal of the polarity of the electromagnetic field (one million times per second).
Heat generation is almost instantaneous and allows a perfectly controlled process thanks to rapid and uniform heating. Additionally, almost all of the energy is transferred to the treated product, dramatically reducing energy losses.
- PSelective properties
Thanks to the polar properties of water, microwaves and radio frequency can heat wet materials very quickly. Specifically, they have the ability to evaporate water quickly and selectively from many materials. This is because water molecules are highly polarized, more so than most substrates on which they are typically found.
This property is used in many fields, including the food industry and industrial heating in fact, anywhere where drying is involved.
- Correct frequency
Other frequencies are used in certain countries, depending on local regulations. Each of these frequencies has specific properties, such as different penetration depths.
Depending on your application, Grupo Acyc will always select the most appropriate frequency to optimize the effects you are looking for.
- Safe technology:
Although microwave technology only has a thermal effect, the high power used requires certain precautions. Therefore, all our equipment is equipped with redundant sensors and interlocks, as well as a microwave leak detector, which will immediately cut off the power if necessary.
Good conductive materials, such as metal, are usually not passed through or heated by microwaves and radio frequencies, since they do not have sufficiently large dielectric losses. For this reason, most microwave equipment is made of stainless steel, which perfectly blocks radiation, while offering excellent durability and cleanliness.
- Union of processes: Our advanced technologies can be combined with other more traditional ones, such as hot air, steam, infrared, etc. to get the most out of the combination. For example, you can cook a dessert quickly and evenly with microwaves, and achieve final browning on the surface with infrared.

Reduced production times in pasteurization, heating, cooking and thawing of a wide variety of products:
It represents a great opportunity for those companies in the food sector that want not only to produce innovative products, but also to automate their process and reduce energy costs. In the particular case of pasteurization of dishes prepared by microwave, for example, by applying said process to a bag of vegetables it is possible to reach temperature values with the desired pasteurization capacity much more quickly than with a conventional thermal process in an autoclave, even achieving more of a double pasteurization factor in a quarter of the process time. Similarly, a continuous industrial microwave equipment can obtain the required pasteurization value for a prepared dish in just 15 minutes, while about 105 minutes of treatment are needed through a thermal process.
Main applications:
- Defrosting and tempering meats, fish and foods in general.
- Thermal stabilization and bacterial inactivation (pasteurization or sterilization) of packaged foods (fresh pasta, baked goods) and liquid products (fruit products, liquid eggs, etc.)
- Fried without oil.
- Industrial bakeries.
- Drying in ice cream/pastry shop.
- Toasted nuts.
- Pasteurization and disinfection.
- Drying of textile fibres, yarns and fabrics after dyeing or other wet treatments.
- Drying of leather and technical textiles (glass fibers, polymer foams).
- Conditioning drying and gluing of wooden materials (laminate, profiles, parquet, cork, MDF, etc.) and paper substrates (paper, corrugated cardboard, cardboard tubes, etc.)
- Partial dehumidification before firing or sintering of ceramics and refractory materials (sanitary appliances, pottery, catalytic supports, etc.)
- Preheating of thermosetting powders and welding of thermoplastics.
- Drying of foundry sand, molds, etc.
We offer the best solutions in the industry now throughout Latin America.
The radiofrequency drying method and thermal treatment, thanks to its endogenous, selective and controlled heating mechanism, allows numerous benefits to be obtained both from a technological, operational and economic point of view, as well as considerably reducing thermal treatment times, improving the productivity and competitiveness of companies.
