Radio Frequency Industrial Defroster THERIO

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 labor cost.

UNIFORM DEFROSTING
Meat, fish, vegetables, fruit etc. either in blocks or IQF can be defrosted in a few minutes up to -1/-3°, with no drip loss. The process is uniform throughout the whole mass of the product, regardless of its size, weight and shape.

NO BACTERIAL DEGRADATION OR CONTAMINATION
Either loose or packaged products can be RF defrosted with no bacterial degradation thanks to the fast process. Bacterial cross-contamination among different product pieces is eliminated in packaged product. The RF defrosters are also equipped with an efficient CIP system for the sanitization of the conveyor belt carrying the product.

IN-LINE PRODUCTION
The process is carried out in-line, ensuring handling efficiency, labor savings and operational flexibility.

ACCURATE PROCESS CONTROL
The RF power delivered by the machine can be easily adjusted and automatically controlled based on the specific needs of each particular product, thus ensuring a defrosting process up to the desired temperature range and the best quality results, minimizing human errors and eliminating product waste at the same time.

LARGE PRODUCTION CAPACITY IN A SMALL SPACE
The reduced footprint of RF defrosters enables food companies to reduce drastically the area dedicated to the thawing process. The modular design allows to increase the production capacity at a later stage. The PLC ensures an easy and seamless integration into fully
automated production lines.
