N₂ or CO₂ for Temperature Control of fresh blended & Frozen pet foods

Higher Productivity for High Quality Products

Rapid heat removal with either liquid nitrogen or pressurized carbon dioxide gas precisely controls the processing temperature in premium pet food products. Exact processing temperature helps to ensure the thorough incorporation of protein, fat, seasoning and essential ingredients during grinding and mixing for fresh products. 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.

In pet food manufacturing, time is money. Through the use of liquid carbon dioxide or nitrogen, Linde's ACCU-CHILL^® BI and ACCU-CHILL^® CBC meat mixer injection systems help pet food manufacturers shorten chilling and freezing times. The ACCU-CHILL system evenly mixes fats, ingredients, and spices, which leads to a properly formulated product. With a control system that ensures liquid cryogen is consistently injected, the cryogen injection systems can address your pet food production’s temperature control needs while increasing throughput and quality.

For a growing segment of the population, pets are people, too. At least when it comes to better quality pet food options. As pet owners become more health and ingredient conscious for their own diets it carries over into the health of their pets and the ingredients that they look for in their pets’ food. 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.

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 gases in combination with properly sized 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.
