A chilled chain is a bunch of processes - production, chilling, warehousing, picking, transportation, final destination on displays of groceries and others - of particular products that must be kept during the entering process in a rigorous controlled temperature. During the primary chilling, meat temperatures, for example, must be reduced below 7°C. There, the meat will be submitted to a temperature of -15°C to -70°C during the first stage of the process until it achieves 7°C. To keep the shelf life of the product, for example, transportation must be between -1°C to 0.5 °C. James (1996).
