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

The flow charts illustrate the process by which frozen fish pie is generated from potatoes and fresh salmon

together with

some necessary ingredients.

Overall

, the key point to note is that

this

is a dual process, from yam to chips, and from fresh salmon to ready-made fish pie, starting at different junctures. Notably, an automatic method is applied to the first process,

whereas

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

Initially

, potatoes, delivered to the factory line up to a month in advance, are automatically cleaned, peeled and sliced into small pieces.

Next,

these slices are dealt with in boiled water, and after being chilled for a

while

, they are stored for the next preparation.

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. After cooking, skins and bones are removed by three workers and

then

checked by another inspector.

Following

this

, the pre-prepared peas, sauce, and chips are wrapped manually with the fish to produce the final products, which are frozen prior to being stored or dispatched.
