Pet food raw materials including fresh chicken, duck meat, egg yolk particles and raw meat bones lose minimal nutrition when processed by Vacuum freeze dryer Freeze-drying technology.
High-temperature baking and air-drying break down animal protein and taurine inside pet raw materials; only Freeze dryer Lyophilization locks full original nutrition without chemical additives.
Medium-size Industrial lyophilizer is the mainstream equipment for pet food factories, balancing daily production output and factory space occupation for batch Freeze-drying processing.
Pet snack brands use Bench-top freeze dryer to test different meat matching formulas, recording taste and nutrition retention data before mass production on large Freeze drying machine.
The low evaporation temperature (-30℃ ~ -45℃) of our Industrial freeze dryer avoids protein denaturation inside fresh meat during the whole Lyophilization cycle.
Freeze-dried pet snacks produced by Vacuum freeze dryer have loose porous texture, easier for cats and dogs to digest and absorb compared with ordinary oven-dried feed.
No preservatives are required for freeze-dried pet food processed by Freeze dryer; thorough sublimation dehydration greatly extends product shelf life.
Many new pet brands start their production line with one Bench-top freeze dryer first, then upgrade to multiple sets of Industrial freeze dryer after market order growth.
