New Defrosting Technology Using Cold Steam
Defrosting frozen raw meat and poultry for processed products requires a quick and efficient process that doesn't decrease the value of the thawed product. Technology provider GEA has created a solution using cold steam under vacuum conditions that completes the job faster than when using conventional methods. GEA has developed the ColdSteam, which works in conjuction with the GEA ScanMidi tumbler, injecting steam into a highly controlled vacuum drum to gently but rapidly defrost meat and poultry, reducing lead times and enabling food manufacturers to respond more quickly to orders. At the normal atmospheric pressure of 1 bar, water boils at 100°C (212°F). However, under the 95% vacuum (0.05 bar) conditions of the ColdSteam, it boils at the much lower temperature of 33°C (91.4°F). The steam is then injected into the drum at this temperature which does not scald or damage the meat, nor cause denaturation of proteins. The steam condenses on the cold meat, and efficiently transfers its thermal energy, significantly speeding up the defrosting process, whilst keeping the colour, binding properties and structure of the meat intact. The system is suitable for a wide range of meat and poultry products. The speed and angle of the system can be adjusted according to requirements, and the process is very gentle, ensuring that damage to the products is at an absolute minimum.
New Nitrogen-based Cull Method For Laying Hens Gas separation specialist Oxair has launched a nitrogen-based system which gives egg-laying poultry a distress-free send-off at end of life. As the price for layer-meat has reduced significantly in recent years, the outlay involved in shipping spent layers off to poultry processing plants has made this option commercially unviable for many poultry farmers. The commonly preferred method, gassing with carbon dioxide, can cause distress to poultry. Oxair’s Anoxiatec equipment guides poultry into a controlled nitrogen environment, into which nitrogen is injected. The birds are gradually put to sleep within two to three minutes and at no time regain consciousness or experience distress. Similar methods using nitrogen have previously been trialled; however Oxair’s enclosed system ensures no danger to the operator and no risk that the birds may regain consciousness or fight the procedure.
New Poultry Incineration Solution Launched A new high throughput agricultural incinerator has been launched by Staffordshire manufacturer Addfield Environmental Systems aimed at operators of large broiler houses. Leedsway Farms recently invested in the A50L to dispose of fallen stock. It is able to achieve almost continuous loading and operation. It is capable of managing in excess of 1 tonne a day or as little as 100kg. Waste can to be loaded almost continuously via an automated hopper and bin tipper system. “We work with farms of all sizes from micro small holdings through to some of the largest pig and poultry producers in the world,” said James Grant, business development director at Addfield.
