Abstract

PURPOSE: A feed for raising fish is for producing the nutrient feed made of animal materials such as fish waste or animal organs and plant materials such as beans or wine lees. And the other aim is capsulating feed by coating the materials with insoluble stuff to prevent nutritions from outflowing. CONSTITUTION: A feed for raising fish is produced by: putting in animal materials such as fish waste or animal bonds and organs, and plant materials such as beans or wine lees respectively in 90-100°C plant oil and animal oil in airtight cookers; heating the oil under the condition reducing pressure 700-750mmHG for 50-60 minutes; dehydrating the respective materials, and removing oil from the materials with a centrifuge; mixing the plant materials and animal materials and forming the feeds; capsulating by coating the materials with insoluble oil.

Description

Manufacturing method of farmed fish feed {MOTHOD OF PRODUCING FOR FEED}

The present invention relates to a method for producing a feed for aquaculture fish by mixing animal raw materials such as fish residues, animal bones or internal organs, and vegetable raw materials such as soybeans and forages.

Conventionally, fish foods such as Iwachi, Saba, and Ebi were used for the production of tuna such as Hamachi, Thailand, and Aji, but they are expensive and have a low preservation rate, and most of them are scattered in the water, causing serious waste of raw materials. Since it was decayed in the bottom of the farm, it caused pollution.

In recent years, food has been developed in which fish are processed on dry pallets to prevent waste of raw materials.

However, since all food is mainly made from animal and plant protein raw materials such as Iwachi, Saba, Ami, and Ebi, fish are poor in nutrition and lack of resistance to various diseases of fish, and fish are easily killed. There was a problem that loses its distinctive flavor.

The present invention has been made in order to solve the above problems, and the object of the present invention to prepare a feed rich in nutrients by mixing animal raw materials such as fish residues, animal intestines and soybeans, forge, etc. have.

Still another object of the present invention is to prevent the outflow of nutrients by encapsulating by coating the surface of the feed with a poorly soluble substance on the surface of the feed.

The present invention for achieving the above object is a preliminary heating of animal oil, vegetable oil, such as fish residues, animal bones, raw materials such as intestines, vegetable raw materials such as bean sake, etc. The oil temperature of animal and vegetable oil is heated under reduced pressure, and the water in each raw material is dehydrated, and after dehydration, dehydration treatment is performed using a centrifugal separator or the like, and then the animal and vegetable raw materials after dehydration are mixed. To form a mixed raw material and form a pallet.

Hereinafter, an embodiment of the present invention will be described in detail. First, 1000 kg of each fish residue or animal raw material is introduced into a sealed container.

In this cooker, animal and vegetable oil, a single oil, or a mixed oil are accommodated. The raw material is heated to a temperature of about 100 degrees by heating the oil by steam injected into the cooker jacket shaft, and the inside of the cooker is stirred slowly.

In the heating operation, the initial pressure of the raw material is reduced to a small degree, and the surface water of the raw material is dehydrated by heating the oil, followed by a reduced pressure of 700 to 750 mmHG, followed by heating for a predetermined time (50 to 60 minutes). Is carried out.

Then, the raw material is taken out and deoiled using an extruder or a centrifuge to prepare a powdery animal raw material.

After the oil temperature dehydration treatment of each of the fish residues or animal raw materials or in parallel, the vegetable raw materials are subjected to oil temperature dehydration using a separate cooker to produce powder.

In the case of vegetable raw materials, vitamin A, C, iron and the like contained are weak to heat, so the oil temperature dehydration treatment temperature is preferably about 100 degrees.

Thereafter, the various powdered bodies are mixed to produce raw materials, and the raw materials are palletized using a molding machine as necessary, to produce a cultured feed for adult fish.

At this time, the surface may be encapsulated by coating a poorly soluble oil on the surface.

As described above, according to the present invention, waste can be recycled by feeding wastes such as bones and internal organs of animals, and formed into capsules for easy storage, and when distributed to aquaculture farms, poorly soluble oil coated on the surface is dissolved in water. Being able to eat meat will be easier to feed.

Claims (1)

Residues of fish, animal bones, raw materials such as intestines, and vegetable raw materials such as soybean dregs are put into animal oil and vegetable oil preheated to about 90 to 100 degrees, respectively, in separate airtight containers, and the oil temperature of animal and vegetable oil is reduced. Heated in the state, dehydration of water in each raw material, dehydration treatment using a centrifugal separator or the like after each dehydration, and then mixed with the animal raw material and vegetable raw material after the dehydration treatment to form a mixed raw material, the pallet phase Method for producing a cultured fish feed, characterized in that formed by.
