B) Pouring baskets in to the reception tank of
the selecting/grading line containing iced water (max
5c), regulating the speed of the converyor belt to
make it possible to control over the defected shrimp
(broken, soft or moulted shell) (this process is very
effective for the quality of the product), grading
through the sorter.
NOTE 1: Residual
sulphite should be analysed too at this step so it can
be decided if it is less than 80PPM, an additional
treatment with a 2% sodium metabisulfite solution (1
minute) must be applied.
NOTE 2: The
uniformity of the product must be observed between 1/1
to 1/3.
C) The 2050gr of graded shrimp is weighed and
manually packed in boxes.
NOTE 1: The net
weight of each 2kg box must exceed 2000-2010 gr after
defrost (by a digital scale)
NOTE 2: Large
sized shrimp must be placed on top and bottom of the
boxes.
NOTE 3: Boxes will
enter in to the plate freezer or tunnels in the upside
down position.
NOTE 4: Labels
attached on the boxes should include the tracking
code, the EEC agreement number and additive used as
anti oxidant.
D) Freezing includes the following systems:
- Plate freezer: Under-40 c for 4-5 hours (deep frozen
down to -180c)
- Tunnel freezer: Under -42c for 10-12 hours
- Combining system: pre-freezing all the product in to
the plated freezer down to -10c within 2 hours. Then
transferring the product to tunnel to finish the deep
freezing process down to -18c about 4-6 hours.
E) Packing: Putting the frozen boxes in to
master cartons and transferring to -25c cold stores.
NOTE 1: The boxes
and master cartons must be handled with special care
with no shocks.
NOTE 2: The
process must be as rapid as possible to prevent the
boxes from thawing.
NOTE 3: Labeling
must be carried out with special care so that all the
information's on the boxes correspond to the ones on
the master cartons.
F) Storage and Exportation includes storing in
the cold store and transporting through containers to
the port.
NOTE 1:
Temperature storage must be -25c. Storage must be
organized by sizes, by freezing dates and by lot
numbers also each carton must be stamped with the EEC
number.
NOTE 2: Maximum 2
to 3 hours are needed to load a 40 feet container.
NOTE 3: The
shipping report must mention the amount of cartons and
kilos for each size, the temperature of the product,
the one of the storage room, the one set on the
container, the date and time when loading began and
when it was finished.
NOTE 4: A map of
the load must be provided to the final customer,
giving the composition in number of cartons by size.
NOTE 5: It is not
necessary to pre-cool the container before loading
because this make condensation when opening and will
wet the cartons and then form rime on them.
NOTE 6: The quality control manager must
be equipped with a needle thermometer and a
calculator. |
