Among other terms, the process is also known as spray cooling, carcass spraying, evaporative cooling spraying and carcass chilling. After the animals are slaughtered and the carcasses are fed into the chiller room, the common practice is to circulate cold, dry, fan-forced refrigerated air over the carcasses. This process draws moisture from the meat, which leads to shrinkage and weight loss. The evaporation is fairly rapid in the initial stages, as there is a large difference between the freshly slaughtered warm carcass temperature and the chiller air temperature. Weight lost from carcasses that are not spray chilled will vary between chillers. However, typical results show a 1.5 to 2% reduction in weight from the beginning of the process to the end. The AutoJet® Carcass Chilling Spray System from Spraying Systems Co. uses a range of spray nozzles to successfully offset the evaporative loss during the carcass chilling process. The system’s programmable controller accurately monitors the timing and the amount of water sprayed between spray cycles in order to minimise the shrinkage to as close to zero as possible. Other features and benefits include the ability to monitor water usage for each cycle, accurate water pressure and temperature control as well as savings on energy and refrigeration expenses. Cleaning time in the chiller room can be reduced significantly as the water on the floor stops blood and fluids from drying, making it easier to rinse and clean. In addition, boning room workers have indicated their preference for processing spray chilled carcasses. The AutoJet Carcass Chilling Spray System has been shown to reduce the total loss of carcass weight to 0.5% or less, which can lead to savings of thousands of dollars per year. The system has been successfully implemented in several lamb, beef, sheep, venison and pork processing plants across New Zealand. Spraying Systems Co. are able to offer turnkey solutions that encompass the entire spray chilling process as well as upgrades and retrofits for existing installations. Their local technical support and experienced engineers will ensure that the best solution is offered to suit client operations. ARE THERE BENEFITS TO SPRAY CHILLING?
