Fish Meal
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.
