OverviewRadio Frequency (RF) tempering minimises drip loss in frozen fruits and vegetables while preserving texture, flavour and freshness. COLDWAVE+ processes blocks, individual portions and packaged goods, delivering fast, uniform defrosting without compromising product quality.
Key features- In-line Radio Frequency rapid defrosting/tempering solution for vegetables, fruits and other food products.
- Handles IQF products, blocks and packaged goods (PE film/liner or bag, open or vacuum-packed, PE+carton, PP crates or trays) and bulk product.
- Multi-position adjustable upper electrode system to accommodate different product sizes and shapes.
- Wide conveyor belt for a broad range of sizes and weights; standard configuration handles pieces from a few kg up to 30 kg and products up to 23 cm in height.
- Machine dimensions and configuration customisable on request to process larger or heavier blocks.
- Different conveyor belt types available depending on product and packaging.
Processing examples and typical defrosting times- 20 kg blocks of carrots or onions: approximately 15 minutes.
- 25 kg blocks of butter: reach +4°C in about 40 minutes.
- Fruit-based blocks (carrot juice, coconut juice, kiwi purée, crushed pineapple) in 10–20 kg blocks: 35–48 minutes.
- Egg white blocks: approximately 42 minutes.
- IQF strawberries: approximately 19 minutes.
- Raw bread dough (330 g pieces), before and after proving: reaches correct temperature range in about 10 minutes.
- Soft cheese in 350 g packages: defrosted evenly in about 15 minutes.
