Study On Precooling Technology Of Carcasses In Chilled Fresh Pork Production

Overcome the cold-meat hot meat, frozen meat in the quality of the shortcomings and defects, soft, elastic texture, taste good, taste delicious. Pre-cooling processes but there is the problem of excessive wear and tear. This paper studies the process of carcass water loss in the pre-cooling law, pre-cooling heat loss is a result of carcass cooling process in the formation of cold and hot swap, hot IOUs through the evaporation of water to release its heat absorption cooling capacity, the water evaporation is inevitable and irreversible. Pre-cooling loss is the result of interaction of many factors, both external causes of its formation, there are internal:external factors that pre-cooling process, the IOUs own internal quality.This loss test from the lower external and internal pre-cooling point of view, considering temperature, humidity, wind speed, coating loss and other factors on the impact of pre-cooling, and strive to get good results, pre-cooling losses from 1.7% to 1.1% of the ideal level.In this paper, obtained using a cooling method, the IOUs library directly to the carcass surface, spray fine mist, or IOUs library installed in the humidifier, with relative humidity of 99% of the cold air to cool the white bars, white bars can significantly reduce the pre-cold loss.This study compared the Sec cooling method and a cooling method pigs wear and tear white bars, white bars the amount of surface water evaporation at the beginning of a quarter of pre-cooling time, the weight loss of about one-half of the estimated more than half, Therefore, measures to reduce the loss of a key pre-cooling the beginning quarter of the time in the pre-cooling. Sec cooling method is better than a cooling method to improve the quality of flesh. Ante with good management system, resting on the pig to maintain a good physique to improve pig meat quality and reduce the loss of pre-cooling has important practical significance. Ma also helped change the role of electronic technology, but is estimated to kill way more conducive to using set of products flesh. Pre-cooling of the three sections of exploring to do some innovative, loss of pre-cooling is more reduced.
