From frozen to final mix in one machine
GEA mixers equipped with ColdSteam technology are designed to optimize the tempering of fully frozen raw material and prepare it for forming into premium quality products. The technology is fast, reducing tempering time down to minutes instead of hours, and is carried out in the same machine as high performance mixing, so only a single unit is required.
The GEA ColdSteam M defrosting technology provides fast tempering of fully frozen raw material to create a homogenous mix for formed products. The technology rapidly defrosts the frozen material by delivering steam under vacuum conditions, which effectively then uses the thermal energy, rather than heat itself, to defrost. Transferring thermal heat by means of 33 °C steam ("cold steam") means that materials are defrosted within minutes, while scalding or protein denaturation.
Main applications for ColdSteam M industrial defrosting technology include the tempering of fully frozen raw material ready for forming into premium quality products such as fish burgers, vegetable and meat replacement products and chicken nuggets.

Defrosting and mixing in one unit
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.
