Abstract
A seaweed feed rich in crude protein, I, Ca and P is prepared from kelp dregs through calsifying it to obtain the clacified floc, dewatering, baking, pulverizing to obtain class-one product, grinding seaweeds, spray drying, pulverizing, and mixing it with said class-one product to obtain class-two product.
Description
Technical field
The present invention relates to the processing method of feeds such as a kind of livestock and poultry, particularly a kind of processing method of Sargassum protein feed.
Background technology
In recent years, China's aquaculture development is rapid, feed is in short supply, especially the shortage of protein feeds has become the comparison distinct issues, is accompanied by the sharp increase of population and a large amount of minimizings in arable land, and the people is becoming increasingly acute with the contradiction that the raising livestock and poultry strive grain, therefore, seek new feed resource in the algae of ocean growth, and be processed into protein feed, having become needs the urgent scientific research problem that solves.Distributing in the ocean and reaching up to ten thousand kinds algae, comprise 10 of Chlorophyta, Phaeophyta, Cyanophyta, Rhodophytas etc., contain abundant algal polysaccharides, protein, fat, vitamin, mineral matter at these fronds, and the physiological activator with special efficacy, provide the raw material storage of food, feed and medicine.There are wide marine site and very long coastline in China, and marine algae resource is very abundant.Also it needs to be noted, China has large quantities of algin processing enterprise, the sector is utilizing marine alga processing to extract a large amount of discarded object--the kelp residue of meeting generation in the process of algin, this kelp residue mainly is made up of the sea-tangle piece of not catapepsis, sea-tangle fiber, carbohydrate gum, sodium alginate glue etc., is alkalescent; The method one that present stage handles usually to kelp residue is the outward transport landfill, method two is made bio-feritlizer, method one is that kelp residue is abandoned as refuse, very easily cause the environmental pollution and the wasting of resources, though having carried out kelp residue to handle again, method two forms organic fertilizer, but this processing only is a primary treatment, does not make it obtain more fully effectively utilizing.
Summary of the invention
Task of the present invention is to provide a kind of processing method of Sargassum protein feed, and it is a raw material with kelp residue of the prior art, handles through processing, and the protein feed that obtains being suitable for raising livestock and poultry is turned waste into wealth, and also can help reducing environmental pollution.
Its technical solution is:
The processing method of a kind of Sargassum protein feed of the present invention, it has following steps:
A chooses kelp residue as main material;
B carries out calcification to kelp residue, obtains the calcification flocculate;
C dewaters, dries, pulverizes the main material body of powder that obtains as the one-level finished product with above-mentioned calcification flocculate.
D chooses suitable marine alga as additional raw material;
E obtains additional raw meal opisthosoma with seaweed additional raw material defibrination, spraying oven dry, pulverizing;
Above-mentioned main material body of powder of f and the composite mixing of additional raw meal opisthosoma obtain the secondary finished product.
Above-mentioned steps e adds the dilution water body in the seaweed additional raw material defibrination, above-mentioned dilution water body is the kelp soaking water of obtaining in the algin process, makes the solid content that obtains the algae slurry at last be controlled at 15%-30%; Above-mentioned algae slurry was deposited 24 hours-48 hours, carried out degradation treatment; The back adopts 80 orders-100 purpose filter to filter, the algae slurry that obtaining can be used for spraying dries; The spraying baker is adopted in the spraying oven dry, 180 ℃ of-210 ℃ of oven dry of spraying, carries out ultra-fine grinding again, obtains the above-mentioned additional raw meal opisthosoma of 150 orders-200 purpose; Before dehydration is carried out in above-mentioned steps c, with clear water calcium chloride superfluous in the above-mentioned calcification flocculate is flushed out, the backwashing manner of taking is with in the calcification flocculate input washing strand cage, dash with clear water pair twist cage and drench to clean, make calcium chloride in the calcification flocculate be fused in the water and with discharging in the lump towards trickle.
Calcification among the above-mentioned steps b can realize like this, adds 1%-2% hydrochloric acid in above-mentioned kelp residue, makes its pH value reach 3.5-4.5, adds 4%-6% calcium chloride solution again, makes its flocculation fully.
Above-mentioned steps c in its dehydration, removes the part of moisture content in the above-mentioned calcification flocculate, and the water content that makes the calcification flocculate is in 65%-75% scope; In its drying course, remove the major part of moisture content in the calcification flocculate after the above-mentioned dehydration, obtain the dry solid content of water content in 10%-20% scope; In its crushing process, with above-mentioned dry solid content fragmentation, the size of particle is in 40 orders-100 order scope.
Above-mentioned seaweed additional raw material can be selected any in spirulina, natural mouse tail algae and the sargassum for use; Or the mixing of selecting above-mentioned two or more marine alga thing for use.
The weight portion proportioning of above-mentioned main material body of powder and the composite mixing of additional raw meal opisthosoma is: main material body of powder 95～50, additional raw meal opisthosoma 5～50.
Processing method of the present invention can be carried out calcification processing with the glue that contains in the kelp residue, forms to be beneficial to the flocculate that other solid contents are together processed in follow-up and the kelp residue, and various effective ingredients can be fully used; Make the main material body of powder, can be convenient to the storage transportation directly as feed first, second its main material as composite feed can be convenient to and other raw materials such as following additional composite mixing of raw meal opisthosoma.The secondary finished product that aforesaid way is produced, not only contain kelp residue as various nutritions that main material comprised, and, also can make full use of other algae of being rich in nutrition as additional raw material, on the basis of contained nutrition of aforementioned kelp residue and content, obtain more effectively replenishing and adding, be particularly conducive to the crude protein content that improves finished product, make this secondary finished product feedstuff be rich in nutrition, effective ingredient more rationally comprehensively.In the aforesaid way, the solid content that obtains the algae slurry at last is controlled at 15%-30%, helps follow-up spray-drying; Carry out degradation treatment, various compositions are further separated out; Carry out the ultra-fine grinding of 150 orders-200 purpose, can effectively destroy the cell membrane of frond, be easy to digesting and assimilating of livestock and poultry, improve the utilization rate of feed.In above-mentioned additional raw material defibrination (can refer in the raw material in the process of grinding or pulping medium) add the kelp soaking water of obtaining in the algin process and dilute, can further utilize compositions such as iodine in the kelp soaking water, alcohol, phosphorus, carbohydrate gum, polysaccharide colloid, inorganic salts, promote the nutrition of feed comprehensively.
The processing method of Sargassum protein feed provided by the invention is the discarded object that the algin processing industry produces--kelp residue provides a kind of brand-new approach that utilizes, and turns waste into wealth, and reduces environmental pollution, can produce bigger economic results in society; In addition, also can make full use of other marine algae resource, carry out composite mixing and obtain being rich in feed products such as crude protein, iodine, calcium, phosphorus, make its nursing that is suitable for livestock and poultry more, help promoting the development of China's feed processing industry.
