Radio Frequency Dryers
RF drying ensures fast and efficient moisture removal and levelling, increasing shelf-life and cutting processing costs.
The drying process plays a decisive role in creating high-quality products. Radio Frequency dryers have been developed on purpose to remove the excess moisture content from many substrates in minutes, replacing slow and expensive conventional drying systems. The RF technology is particularly suitable for the postbaking drying of baked products (biscuits, crackers, crispbread, etc..). Indeed, final moisture reduction and levelling is a difficult task to achieve in baking ovens: due to the crust formation during baking, moisture evaporation takes about 60% of the energy of the entire process and about 30% of the overall oven length. Differently, Radio Frequency is selective towards water and ensures drying in minutes with no surface over-baking or excessive colouring. Hundreds of RF post-baking dryers have been installed in industrial bakeries in the last 40 years, making it the most popular RF drying application in the food sector.

RF Defrosting of meat, fish and vegetables
RF defrosters ensure a rapid and uniform defrosting process, eliminating the need for large thawing rooms and minimizing the drip loss.
Conventional defrosting systems (still air thawing, forced air/blast thawing, water sprinkling, water immersion systems, etc..) are slow and often generate product waste due to the poor process control. Differently, RF defrosting is an endogenous and instantaneous method that delivers the product ready for the next step in a few minutes: the product to be defrosted, either in blocks or IQF, is placed on the conveyor belt of the RF machine and is submitted to rapid dielectric heating that brings its temperature just below the melting point of water, with no drip loss or bacterial deterioration. In this way, other than saving time and preserving quality, last-minute orders can be easily managed and product waste is completely avoided. Furthermore, being a continuous and in-line process, multiple handling is eliminated, with huge savings in labour cost. with no drip loss or bacterial deterioration.

Product category: Pasteurizing and sterilizing machines
RF pasteurizers for loose and packaged products
The RF pasteurizers ensure a rapid and even microbial inactivation, preserving at best food physical, sensorial and nutritional properties.
The outstanding benefits of the RF technology can also be achieved in the disinfestation, sanitization and pasteurization of various food commodities, intermediates or finished products, either in bulk or packaged. Food processors often rely on steam or other conventional heating systems (mostly based on hot air circulation or surface heat exchangers) for the microbial inactivation/stabilization processes: the heat transfer is generally slow and uneven, severely damaging the physical, sensorial and nutritional properties of the product. Differently, the ability to penetrate deep inside the product mass and generate heat evenly and instantly is, at the same time, the main characteristic and the main benefit of RF heating. Practically, in RF pasteurizers the product is submitted to a rapid and gentle dielectric heat treatment for a few minutes, that leads to live cell destabilization and microbial inactivation. In this way, food substrates can be sanitized while preserving their physical, sensorial and nutritional properties. RF machines are rather small in size and modular, so that additional production capacity can be easily added at any time. This makes convenient the integration of the RF technology into existing production lines. Adjustable parameters in the PLC allows the operator to set the appropriate process recipe for each product. Either batch or conveyorized model RF machines are available, depending on the product/process type and production capacity requirements. The machines and their ancillary equipment are designed and supplied according to the customers specific requirements.
