  GEA Food Solutions ColdSteam® Technology inside
ColdSteam is a highly controlled process using steam under vacuum to efficiently defrost meat without scalding or damaging it, nor cause denaturation of proteins. GEA Food Solutions pioneered this technique, and currently leads the market with the innovative ColdSteam. GEA Food Solutions applies defrosting under vacuum in both tumblers and mixers. Fast defrosting under vacuum increases operational flexibility as it reduces lead-time in the production process. Compared to traditional defrosting techniques such as tempering chambers or microwave systems, ColdSteam delivers consistent results, no incomplete defrosting or hot spots. In other words, it enables meat processors to satisfy the increasingly higher demands of their customers.  What is ColdSteam?
At normal atmospheric pressure (1.0 bar), water boils at 100°C (212°F). In a vacuum, it boils at a lower temperature. In a 95% vacuum (0.05 bar), the boiling point of water drops to 33°C (91.4°F). The resulting steam also at this temperature condenses immediately on to the cold meat, and efficiently transfers its thermal energy, significantly speeding up the defrosting. The steam at 33°C does not scald or damage the meat, nor cause denaturation of proteins. The general benefits of vacuum, controlled, defrosting: Significant reduction of defrosting time Increased yield, no weight loss through purge (drip loss) Substantial reduction of manualhandling Increased operational flexibility Faster reaction to customer demands Verified food safety guarantee Top and easy to use hygienic design For high variety of products (bone-in and boneless meat& poultry, shrimps)
ColdSteam Mixer defrosts pre-ground or crushed frozen meat for further processing in around 10 minutes ColdSteam Tumbler defrosts whole muscle and bone-in products in 3 to 8 hours, depending on the type of products/block size. GEA Food Solutions ColdSteam Tumbler: The GEA Food Solutions ColdSteam Tumbler (T) significantly reduces defrosting time to less than half that of conventional defrosting techniques. Standard executed with a steam expander, cooling/heating on jacket and carriers, integrated vacuum pump and weighing cells.  The GEA Food Solutions ColdSteam T benefits include:
• Substantial reduction (50%) of defrosting time • No drip loss, no weight loss • Substantial reduction of manual handling • Increased capacity, reduced defrosting time à more production time. • Automated and fully controlled process • Three processes in one: defrosting, marinating and massaging Read More on the GEA ColdSteam Tumbler >> GEA Food Solutions ColdSteam Mixer: The GEA Food Solutions ColdSteam Mixer (M) spectacularly reduces defrosting time from days to minutes! The side-by-side mixer is enhanced with steam injection, vacuum pump, integrated weighing cells, and PLC controls. 
The benefits of GEA Food Solutions ColdSteam M include: • Extremely fast defrosting down to 10 minutes. • Substantial reduction in manual handling • Increased capacity, faster defrosting results in more production time. • Automated and fully controlled process • Products are ready for further processing as the meat retains the right temperature Read More on the GEA ColdSteam Mixer >>
