*Processing fish meal as animal feed from fish and seafood

Fishmeal is an important component indispensable in food processing livestock and aquaculture. To manually feed processing in households and farms, livestock farmers use fish meal is mostly homemade, but the production and processing fish meal homemade majority of people are not technically correct , polluting the environment and product quality is not good. To overcome this drawback, the invention processing of animal feed 3A Nguyen Hai Chau effect. Has made the appropriate equipment and experimental success, the technology can produce high-quality fish meal of scale and farm households

.

* Processing fishmeal as feed – Ingredients:

– Raw material for fishmeal production is the use of trash fish such as croaker, snapper, fish alum, sardines, mandarin fish, discus, herring, snapper, fish spines cows, pompano, fish tilapia…

 
– Store the raw materials:
Fresh raw fish preserved by ice + salt. Preserved by ice mixture + 5% salt can keep fish fresh for 16 days. Ice mixture + 15% salt can keep fresh raw fish for 30 days.
Not preserved with a mixture of salt more than 15%, because the processing to proceed to ferment makes material release missing protein, vitamins … reduce quality of fishmeal.
* Processing of fish meal as animal feed – Equipment:
Equipment necessary for the production of fishmeal, including:
– Containers to 400 liters of water used to boil the fish dipped in ripening, yield 50 kg / batch.
– Fish 3A3KW mowers. 220v power 3kw motor running. Productivity 350kg / h
– Centrifuge 3A3KW juiced. 200 cycles / min. Motor-driven power 3kw 220v. yield 50 kg / batch.
– 3A3KW machines to yield 50 kg / batch.
– Oven 3A can adjust the temperature between 60 – 120 ° C, yield 100 kg / batch.
– Shredding Machine versatile productivity 3A2.2KW 150 kg / hour.

Step 1: Handle material:
If the fish are preserved by ice + salt mixed with clean water to flush salt and thawed, until the salt content in fish superiority <1%. Purification of impurities. Then put the fish into fish cutting machine 3A3KW shredded hash with slice thickness 3 – 5 cm.
Step 2: Cook ingredients:
Use a cooking pot with a capacity 400lit mounted pulleys to control the cooking pot fish baskets. Put the ingredients into baskets, 50kg / batch, using pulleys drop into the pot of boiling water. The ratio of water to cook / material = 5/1. Cooking time 2-3 minutes until the fish cooked fragrant.
Step 3: Centrifugal squeezed dry ingredients:
Using centrifuges 200 cycles / min. Once cooked fish, take fish into baskets containing centrifuge 200 cycles / min. Go for 3-5 minutes until no water discharge from the faucet collection of machine translation is fish. Translation mackerel can be packed into cattle feed.
Step 4: How to materials:
Pour the raw fish from baskets on spinner. Spinner running for 8-10 minutes until the ingredients apart into pieces.
Step 5: Drying of raw materials:
Material taken from me at the tray machine mesh, in the oven for 80-85 degrees Celsius in 7-8 hours. Or dried in the sun.
Step 6: grinding mill and packing:
Raw dried over steps taken 3A versatile ADM mill for grinding into powder. Once the powder is discharged into the sealed plastic bags. For fish meal bags in closed containers to avoid insects, rodents vandalism.
Quality Fishmeal
Results showed that, fishmeal production technology on material norms of 4.5 / 1, meaning that production material 100kg trash fish products obtained 22 kg of fish meal and 27 kg centrifugal services. Products with high quality, to fishmeal, no lumps, no mold, has a distinct aroma of fish meal, the sweet taste of protein, pale golden brown.
