Radio Frequency Meat and Seafood Defroster & Tempering Machine
Faster. Safer. More Uniform.
Revolutionise your defrosting and tempering process with MagnaFrost, Strayfield’s advanced Radio Frequency (RF) solution designed for high-efficiency, continuous food processing.
Engineered for precision and performance, MagnaFrost delivers uniform core-to-surface defrosting, minimising product loss while maximising throughput.
Why MagnaFrost?
Traditional defrosting methods are slow, inconsistent, and inefficient. MagnaFrost eliminates these challenges with cutting-edge RF technology.
Uniform temperature distribution
Minimal drip loss
Reduced bacterial growth
Compact, in-line processing design
Unlike conventional methods, RF heating creates a uniform energy field, ensuring even defrosting across the entire product.
How It Works
MagnaFrost uses radio frequency dielectric heating to excite water molecules within the product, generating heat from the inside out.
- No surface overheating
- No frozen cores
- No compromise on texture or nutrition
This results in consistent, high-quality output, batch after batch.
Key Benefits
Perfect Uniformity
Even defrosting from core to surface; eliminating hot and cold spots.
Superior Product Quality
Maintains texture, moisture, and freshness while reducing bacterial growth.
High Throughput Efficiency
Process thousands of kilograms per hour with consistent output.
Sustainable by Design
- Lower energy consumption
- Zero water waste
- Minimal product loss
Space-Saving System
Compact, conveyorised design integrates seamlessly into production lines.
