The diagrams below give information about the manufacture of frozen fish pies. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

The diagrams illustrate the production of frozen fish pies, which come in a microwaveable container and include a layer of ingredients

such

as fresh salmon, peas, sauce, and sliced

potatoes

. In general, there is a dual process, which is named

Potatoes

and Fresh salmon, starting at different junctures. The automatic method is applied to the Potato process,

whereas

the other combines manual labour and technology. The first branch shows how the

potatoes

are prepared.

Initially

, the

potatoes

, delivered to the factory up to a month in advance, are cleaned, peeled, and sliced into small pieces. The potato peelings are thrown away, and the slices are boiled and

then

chilled before storage.

Secondly

, the fresh salmon must be cooked in a steam oven within 12 hours of delivery after lemon juice and salt are added to the slices for several reasons,

for instance

, flavour enhancement, odour reduction, etc. Skin and bones are removed and disposed of by the workforce before being inspected by others.

Following

this

, the pre-prepared peas, sauce, and

potatoes

are wrapped manually with the fish to produce the final products, which are frozen prior to being stored or dispatched.
