The diagram illustrates the various stages involved in the commercial production of frozen fish pies.
Overall, the depicted production process comprises several distinct phases, beginning with the preparation of main ingredients such as fresh salmon, peas, sauce, and sliced potatoes, and ending with the birth of frozen fish pies. The production of fish pies is, in contrast to the previous stage, characterized by a more labor-intensive series of steps.
Following the delivery of sliced potatoes, they undergo a series of preparation steps. Initially, they are cleaned and peeled before being sliced into uniform pieces. Subsequently, the slices are boiled and then chilled to ensure freshness. Once prepared, the potatoes are stored until needed for assembly. In contrast, the process for handling fresh fish is more intricate. Within twelve hours of delivery, the fish is steamed with lemon juice and salt to enhance flavor. Afterwards, meticulous manual labor is employed to remove the skin and bones, followed by a thorough visual inspection to ensure quality.
The next phase involves the assembly of the fish pies. Once the main ingredients are prepared, they are combined in microwaveable containers. nFirstly, the cooked fish is placed in the container, followed by the addition of peas and sauce. Finally, a layer of cooked potato slices is placed on top to complete the assembly. Once assembled, the pies are carefully wrapped and subjected to the freezing process. This ensures that the pies maintain their quality and freshness. Following freezing, the pies are ready for dispatch, either immediately or after a period of storage at the factory.
