Specifications
Advanced technologyColdSteam technology: Using simple physics

GEA ColdSteam defrosting technology provides fast tempering to create a homogenous mix for formed products. The method, which is ideal for defrosting pre-ground frozen meat, exploits the phenomenon that water boils at a lower temperature in a vacuum. The injected steam condenses on the cold meat block, efficiently transferring thermal energy and reducing defrosting time from hours to minutes. The low steam temperature in the vacuum (approx 33°C, instead of above 100°C) means that scalding or protein denaturation is avoided.
