The diagrams demonstrates information about how frozen fish pies are manufactured. Overall, the process involved four stages: prepares all ingredients, cooks and seasons the food, freezes and stores and finally ends up with delivery.
In the beginning stage, all basic ingredients included potatoes, prepared peas, prepared sauce, and fresh salmon from a delivery that takes a month. For the process of dealing with potatoes, the machine will clean, peel, and chop the potatoes into slice pieces through the systemic production line. Then, the prepared potato slices are going to be boiled, chilled and stored. For the fresh salmon, staff will season it with lemon juice and salt, then put it in the steam oven and remove skins and bones. Furthermore, staff will keep inspecting the whole production line.
