Shellfish defrosting chamber COLDWAVE+

for the food industryfor fish

Overview
Rapid Radio Frequency (RF) tempering/defrosting system designed for industrial processing of fish and seafood. The RF process delivers fast, uniform tempering while maintaining physical, organoleptic and nutritional integrity of the products. Suitable for in-line integration in processing lines.

Treatable products

• Species and formats: squid, calamari, octopus, scallops, mussels, sardines, salmon, tuna, swordfish, shrimps, prawns, crawfish, lobsters, cod, pollock, hake, pangasius, halibut, catfish, toothfish, surimi, etc.
• Forms: whole, H&G, fillets, loins, steaks/chunks, shell-on or peeled.
• Product state: IQF pieces or frozen blocks (standard configuration; customization available for larger/heavier blocks).

Machine configuration and processing capabilities
The system features a multi-position upper electrode and a wide conveyor belt to handle a broad range of sizes and weights: standard range from a few kilograms up to 30 kg and product heights from a few centimeters up to 23 cm. Custom electrode and conveyor configurations are available on request to process larger or heavier blocks.

Packaging and product handling
RF field characteristics and multiple conveyor belt types enable processing of packaged products (PE film/liner/bag open or vacuum, paper-film, PE + carton, PP crates or trays) as well as unpackaged (naked) items, minimizing drip loss and cross-contamination risk.

Performance and operating data

• Typical starting temperatures: -20°C to -18°C.
• Typical thawing times: approximately 10–35 minutes depending on product and format.
• Target/final temperatures: typically between -6°C and -2°C to ensure optimal quality.

Media
Operational video available demonstrating in-line rapid defrosting for seafood.
