Industrial defrosting and mixing for frozen raw materials
Reduce frozen material tempering time from hours to minutes, ensuring rapid, consistent mixing that enhances product quality and safety while streamlining your production line.

Rapidly Tempers and Mixes Frozen Food Ingredients
The GEA ColdSteam M represents an innovative step forward in defrosting and mixing technology for the food processing industry. Engineered by GEA, it utilizes the ColdSteam technology to dramatically cut down tempering times, transforming frozen food ingredients into a homogeneous mix for high-quality formed products like fish burgers, chicken nuggets, and plant-based meatballs within minutes. By delivering steam under vacuum conditions, the system defrosts efficiently at approximately 33°C, preventing scalding and protein denaturation.
This equipment is seamlessly integrated into automated production lines, equipped with variable speed twin-shaft mixers for optimal ingredient blending, ensuring consistent quality and enhanced protein extraction. The robust design caters to a wide range of products, from solid to slurry, with capacities ranging from 1,000 to 5,000 liters, addressing the needs of high-speed and continuous operations.
Food processors will appreciate the enhanced food safety inherent in its closed system, reducing bacterial contamination risks. The optional integration of liquid CO2 or liquid N2 cooling allows for processing even within extended formed product ranges. Designed for easy cleaning and maintenance, the GEA ColdSteam M provides reliable performance with minimal downtime, delivering precise and predictable mixing results essential for maintaining product integrity in a competitive market.
