About the Fishmeal Process: |
|
Gone are the days where the
trash fish is utilized for the fish meal production. Earlier the fresh
fish that were not supportive for human consumption lead to the
manufacture of fish meal production. The fish that is diverted for the
production of various byproducts such as the fishmeal is about one third
of the total fish consumption. Normally the low priced fishes having
less market value and those which are disliked in taste and flavour are
reduced to fishmeal. This also helps in maintaining the civic problems
in fishing industry. The Leading Fish meal producers in the world are
Japan. Chile, USSR, Peru, USA, Norway, and Denmark. Of late, India is
finding its place in this group. The company has made its name in
“Quality” and “Capacity” in terms of production. |

FISH MEAL: |
|
The
fresh fish is brought to the factory in iced condition. The icing is
done depending upon the transporting time. The raw material is taken
through the conveyors from the fish tanks through a metal detector (to
catch the metal items) to the “Cookers” which makes use of indirect
steam for cooking the fish in a temperature of 80-85°C for about
25-30min. The cooked fish is later pressed in “Screw Press” to separate
Fish liquor (Press Liquor) and Fish solids (Press cakes). The fish
liquor hereby termed as “Stick water” is collected in a stick water tank
for further oil separation.
The press cake having 40-45% moisture is forwarded to the “Steam Drier”,
so as to reduce the moisture to about 9-10% with the help of indirect
steam at a temperature of 80-90°C inside the drier. The Dried fish meal
is forwarded into the “Pulverizer” for converting into fine particle
size. The fish meal is sieved in a “Siever” to remove the foreign
particles/ bones/ scales and only the fine powdered fish meal is
collected and passed through a cooler maintaining the output fish meal
temperature at 27-30°C. In an aseptic environment the fish meal is
packed directly into an inner coated polypropylene bag of 50kg capacity.
The fish meal thus produced is stored in a well maintained Godown.
Most of the equipments for the production of fish meal are manufactured
and imported from china. The conveyors that are used in the production
line are all Stainless steel materials.
The shelf life of the fish meal is increased by adding antioxidant (Ethoxiquin)
in recommended dosage. |

FISH OIL: |
|
The
Press liquor from the stick water tank is fed into the “Super Decanters”
to remove the solids from the stick water. The liquid of stick water
that is free from solids is fed into the “Super Centrifuges” or “Three
Phase Centrifuges” for separation of water and oil from stick water. The
oil that is produced is the “centrifuged fish oil” which is stored in
Oil storage tanks. |

|
|
|
FISH SOLUBLES: |
|
The stick water that is let out after
the separation of oil from the centrifuges is fed into “Multiple effect
evaporators” to prepare “concentrated fish soluble” (containing 50%
solids and 50% water) and finally dried in the Drier so as to achieve
the “whole meal”. |
