The diagrams below illustrate the steps involved in manufacturing frozen fish pies.
Overall, the production of frozen fish pies involves multiple steps that begin with the delivery and preparation of potatoes and fresh salmon. The process continues with the combination of ingredients before the final product is wrapped, frozen, and dispatched.
In the first stage, potatoes are delivered, cleaned, peeled, and sliced. These potato slices are boiled, cooled, and stored in bags for further use. Meanwhile, fresh salmon is delivered within 12 hours and placed on the conveyor belt for preparation. This includes salting the fish and squeezing lemon juice over it before baking it in a steam oven. After cooking, the skin and bones are carefully removed, and the fish is inspected. Peas and a sauce are then added to the salmon mixture to improve the flavor and topped with prepared potato slices.
Finally, all prepared ingredients are combined and placed into small rectangular containers. These are then sealed and frozen. The frozen pies are finally sent to storage or dispatched for distribution to supermarkets.
