Peeling and freezing shrimp
(Afskalning og frysning af rejer)
|
Denmark
1993
|
Shrimp for human consumption are often
subject to industrial processing (cooking,
peeling, freezing and packing) before distribution to the market.
Process description
The present data
refer to industrial freezing and packing of shrimps
in one factory. The main processes are following: 1) frozen shrimps entering
the factory are defrozen, 2) the defrozen shrimps are matured at 12oC,
3) the shrimps are peeled 4) the peeled shrimps are cooked 5) the cooked
shrimps salted, cooled and frozen individually in a flowfreezer 6) the frozen
shrimps are covered with a thin layer of ice ("glasification") and
packed.
Data collection and treatment
Data have been collected from Naajaq Seafood
Esbjerg A/S in 1993, see Dansk Industri (1995). Average energy consumption per
produced unit has been calculated. It has been assumed that
shells etc. constitute 25% of shrimps.
Technical scope
Energy consumtion from all production
processes
at the factory are
included. Other inputs and outputs such as water consumption and wastewater
generation are not
considered.
Representativity
The Danish fish industri has been subject to
significant energy saving activities after the present dataset has been
established in 1993 and energy consumption in the industry is probably somewhat
lower today.
Validation
No validation has been
performed
Inputs and outputs
Inputs
and outputs associated with
peeling and freezing are shown in the table below. Data
are provided per
2520
kg
peeled and frozen shrimps
at the factory's gate without packaging.
