Description

Technical Field

[0001] The invention belongs to the technical field of fish ball processing equipment and relates to freezing equipment for fish ball production. Background Art

[0002] During fish ball production, the freezing process significantly impacts product quality and production efficiency. Traditional fish ball freezing equipment often suffers from numerous problems: A low degree of automation requires manual operation for everything from loading and sorting fish balls to pallet transfer, resulting in low efficiency and the risk of damage due to improper operation. Inadequate sorting accuracy leads to fish balls easily stacking and sticking together, resulting in frequent collisions during feeding, impacting product integrity. The freezing effect is poor, with uneven cold air distribution, resulting in insufficient cooling of some fish balls. Furthermore, surface moisture cannot be drained smoothly during freezing, further reducing freezing efficiency. Furthermore, the various processes are loosely connected, and equipment coordination is poor, making it difficult to adapt to subsequent automated packaging processes, which in turn restricts the overall production process.

[0003] Therefore, we propose a freezing equipment for fish ball production, which can realize the fully automatic circulation, precise material distribution and efficient and uniform freezing of fish balls. The various processes are closely connected and can meet the quality and production capacity requirements of fish balls and similar meatball products for large-scale production.
