Rapid defrosters for vegetables, fruits and other products “COLDWAVE+”

Radio Frequency tempering minimises the drip loss of frozen fruits and vegetables, which therefore retain their texture, flavour and freshness.
The treatment can be performed on IQF products or blocks. The multi-position upper electrode system and the wide conveyor belt allow to process a wide range of sizes and weights: from few kg to 30 kg and from few cm to 23 cm high (standard configuration). Upon request, the machine can be customized to process bigger and heavier blocks.
Thanks to the characteristics of the RF field and the different types of conveyor belt available, the product can be processed packaged (in PE film/liner or bag, open or vacuumed, PE+carton, PP crates or trays, etc.) or in bulk.
Our radio frequency defrosting solutions are suitable for a wide variety of products, including vegetables, fruit and fruit derivatives, dairy products, dough, and liquid or semi-liquid items. The system efficiently handles blocks, individual portions, and packaged goods, ensuring fast and uniform defrosting without compromising quality.
For example, we defrost 20 kg blocks of carrots or onions in just 15 minutes, while 25 kg blocks of butter reach +4°C in 40 minutes. Fruit-based products like carrot juice, coconut juice, kiwi purée, and crushed pineapple (in 10–20 kg blocks) are defrosted in 35 to 48 minutes. Egg white blocks are ready in 42 minutes, and IQF strawberries in only 19 minutes. Raw bread dough, both before and after proving (330 g pieces), reaches the correct temperature range in just 10 minutes. Even delicate products like soft cheese, in 350 g packages, are defrosted evenly in 15 minutes.
