Problems solved by technology

For example, there is a method of concentrating fish soluble slurry into a paste, but this paste is very inconvenient to use in the feed industry
There is also a method of adding fish soluble slurry to fish meal for drying. This method will cause problems such as increased moisture absorption of fish meal, difficulty in storage, and poor fluidity.
[0003] If fish soluble pulp is made into fish soluble protein powder, it will completely solve the recycling problem of fish soluble pulp, but this effort has not been successful, the main reason is that fish soluble pulp contains substances with strong hygroscopicity, It is impossible to dry the fish soluble slurry into powder by the usual method

Embodiment 1

[0032] The specific operation steps of the preparation method of fish soluble protein powder of the present invention are as follows:

[0033] (1) Send the fish soluble slurry flowing out of the fishmeal production line into a disc centrifuge at a speed of about 6000 rpm, the light phase is fish oil, and put it into a special fish oil storage tank. The heavy phase is deoiled fish slurry, which is sent to the mixing tank.

[0034] (2) Control the temperature of the mixing tank to be 60° C., add 1% calcium acetate under stirring, stir for 10 minutes, and then send it into a horizontal centrifuge.

[0035] (3) Adjust the rotating speed of the horizontal centrifuge to 4000 rpm, the mucopolysaccharide calcium salt precipitate is removed from the slag discharge port, and the fish-dissolved pulp clear liquid flows out from the clear liquid port, and then is sent into the decompression concentrator.

[0036] (4) At 0.02Kg / cm 2 Concentrate the fish soluble slurry under pressure to a ...

Embodiment 2

[0042] The concrete operating steps of the method of the present invention are as follows:

[0043] (1) Send the fish soluble slurry flowing out of the fishmeal production line into a disc centrifuge at a speed of about 7000 rpm, the light phase is fish oil, and put it into a special fish oil storage tank. The heavy phase is deoiled fish slurry, which is sent to the mixing tank.

[0044] (2) Control the temperature of the mixing tank to be 30° C., add 2% calcium acetate under stirring, stir for 30 minutes, and then send it into a horizontal centrifuge.

[0045] (3) Adjust the rotational speed of the horizontal centrifuge to 5000 rpm, the mucopolysaccharide calcium salt precipitate is removed from the slag discharge port, and the fish-dissolved pulp clear liquid flows out from the clear liquid port, and then is sent into the decompression concentrator.

[0046] (4) At 0.02Kg / cm 2 Concentrate the fish soluble slurry under pressure to a solid content of about 30%.

[0047] (5)...

Embodiment 3

[0050] The concrete operating steps of the method of the present invention are as follows:

[0051] (1) Send the fish soluble slurry flowing out of the fishmeal production line into a disc centrifuge at a speed of about 9000 rpm, the light phase is fish oil, and put it into a special fish oil storage tank. The heavy phase is deoiled fish slurry, which is sent to the mixing tank.

[0052] (2) Control the temperature of the mixing tank to be 30° C., add 4% calcium acetate under stirring, stir for 30 minutes, and then send it into a horizontal centrifuge.

[0053](3) Adjust the rotational speed of the horizontal centrifuge to 5000 rpm, the mucopolysaccharide calcium salt precipitate is removed from the slag discharge port, and the fish-dissolved pulp clear liquid flows out from the clear liquid port, and then is sent into the decompression concentrator.

[0054] (4) At 0.02Kg / cm 2 Concentrate the fish soluble slurry under pressure to a solid content of about 50%.

Abstract

The present invention relates to ''fish soluble protein powder and preparation method'', which belongs to the field of animal feed processing. A fish soluble protein powder preparation method, the fish soluble can be processed by being eliminated from fish oil and mucopolysaccharide, and then being concentrated and dried. Through eliminating from fish oil and mucopolysaccharide, the drying performance of fish soluble has greatly improved, after concentrated, the fish soluble is fed into a spray tower with tower wall cooling system, revolving sweep tower system and air humidity elimination system, the fish soluble powder is easily dried, free of moisture and hygroscope, easy preservation and transportation, at the same time the protein content in the fish soluble protein powder is not decreased, which is the lower the high quality materials for animal feed.

Description

technical field [0001] The invention relates to the field of feed processing, in particular to an animal feed raw material fish soluble protein powder and a preparation method thereof. Background technique [0002] Fish soluble pulp is the press wastewater produced during the production of fishmeal. Fish soluble pulp is rich in high-quality protein. According to P.J.BECHTEL, Univ.of Alaska, fish soluble pulp contains 6% protein, pepsin digestibility is greater than 95%, soluble Protein accounts for 70%. The fish soluble protein recovered by appropriate methods can be used in the feed industry as raw material for animal feed. If the fish soluble protein is discharged directly to the environment without recycling, it will cause environmental pollution. Long-term research has been carried out on the recovery method of fish lysate protein at home and abroad. If there is a method for concentrating fish soluble slurry into a paste, but this paste is very inconvenient to use in t...
