Rapidly remove heat and chill to preserve product integrity
For a growing segment of the population, pets are people too. Fresh is widely regarded as better-for-you than processed, so fresh and fresh-frozen pet foods are becoming more in-demand and, consequently, more prevalent. For frozen pet meal and treat products, either nitrogen or carbon dioxide systems quickly reduce product temperature to a set target temperature improving production rate and maintaining high product quality.
Whole muscle cuts, ground product and diced portions are the leading ingredients and require precise temperature control to retain the initial high quality. Liquid nitrogen or liquid carbon dioxide in the gases' coldest, cryogenic form are effective and highly efficient tools to rapidly reduce product temperature. The precise temperature requirements to thoroughly chill or quickly freeze product to a target temperature is key. These Praxair gases in combination with cryogenic freezing, chilling, injection cooling and direct snowing systems allow for the production of not only pet entreés but also improved productivity for a variety of fresh snack, jerky and freeze-dried treats.
