AI Technical Summary
Existing quick-freezing machines have a slow freezing speed, resulting in larger ice crystal nuclei forming in quick-frozen foods, which affects the taste and nutritional value.
A two-stage refrigeration system is adopted. The first-stage refrigeration component performs initial quick freezing, while the second-stage refrigeration component has a greater cooling intensity. Combined with straight and spiral conveyor belts, liquid nitrogen refrigeration components are used for secondary quick freezing to ensure that the food reaches the crystallization temperature before entering the second stage and quickly forms small and uniform ice crystal nuclei.
It shortens the quick-freezing time, reduces the size of ice crystal nuclei, improves the taste and nutritional value of frozen foods, and maintains the advantages of large-volume frozen products.
