Pet food freeze dryer
2025-07-04
Pet food freeze dryer preserves food through low-temperature freezing and vacuum dehydration. FD freeze drying can retain more than 95% of the nutrients in the ingredients, maintaining their original shape, color, and flavor. Traditional high-temperature drying or air drying can cause the materials to shrink and dry. Pet food freeze dryer (pet freeze dryer) uses low-temperature freezing and vacuum drying technology to directly remove the moisture in pet food (cat food, dog food, pet snacks, etc.) from solid ice to gaseous state, ultimately obtaining freeze-dried pet food with a moisture content of<5%.
The three key stages of pet food freeze dryer:
1. Low temperature freezing: Quickly freeze ingredients in an environment below -35 ℃.
2. Vacuum sublimation: In a vacuum environment of<10Pa, solid ice crystals directly vaporize into water vapor.
3. Analysis of drying: Slowly raise the temperature to remove bound water.
The freeze-drying machine avoids the nutritional damage caused by traditional high-temperature processing, does not destroy the original appearance and color of pet food, and has a crispy and rich taste. Freeze dried pet snacks can be stored at room temperature for 2-3 years without the need for preservatives.
The GFD pet food freeze dryer has the core advantages of low-temperature freshness locking, intelligent control, and high efficiency and energy saving, promoting the development of the pet food industry towards high quality and functionality. The future GFD freeze-drying machine provides a new freeze-drying solution for pet food.
