A kind of processing method of seaweed fodderTechnical field
The present invention relates to the processing method of feeds such as a kind of livestock and poultry, particularly relate to a kind of processing method of seaweed fodder.
Background technology
Seaweed plants in the ocean is of a great variety, and 10 of Chlorophyta, Phaeophyta, Rhodophytas etc. are arranged, and the difference by contained pigment in the marine alga is divided into green alga, brown alga, blue-green algae, xanthophyta, chrysophyceae or the like, is divided into tangleweed and little algae two classes by the algae form.Laver in tongue bar, sea lettuce and the red algae in sea-tangle in tangleweed such as the brown alga, undaria pinnitafida, bulk kelp, the green alga, agar etc.; Little algae is a unicellular algae, and its diameter has only several microns, but reserves are huge, has the wide development prospect.Marine alga be can be made into seawood meal through special processing technology.Whole world seawood meal output reaches 50,000 tons at present, and wherein special seawood meal processing factory is all had in states such as Norway, Denmark, Britain, the U.S., Canada, and marine alga is applied to its feeding as feed addictive.The seawood meal of China produces and uses and also is in the starting stage.
Summary of the invention
The object of the present invention is to provide a kind of processing method of seaweed fodder, the multiple natural macro plant in the selection environment, is handled through processing as primary raw material as sea-tangle, undaria pinnitafida etc., obtains being suitable for raising livestock and poultry feed.Feed of the present invention is the nuisance free feed that does not add any artificial hormone, and production cost is low, for natural algae provides new approach in the development and use of domestic animal field of animal feed.Technical solution of the present invention is:
A kind of processing method of seaweed fodder comprises the steps:
A. choose natural macro plant as main material;
B. main material is dewatered, oven dry, machine pulverize the main material body of powder that obtains as the one-level finished product.
Before dehydration is carried out among the above-mentioned steps b, the tangleweed plant that obtains is washed with clear water.
Among the described step b, it is 60%～70% that processed makes the main material moisture; Oven dry is handled and made the main material moisture is 10%～20%, and described main material forms dry solid content; Pulverization process is with above-mentioned dry solid content fragmentation, and the size of particle is 40～100 orders.
Described natural macro plant is sea-tangle, undaria pinnitafida, Enteromorpha, sea lettuce.
The processing method of described seaweed fodder also comprises the steps:
C. choose seaweed additional raw material;
D. seaweed additional raw material defibrination, degradation treatment, spraying oven dry, machine are pulverized and obtained additional raw meal opisthosoma;
E. with main material body of powder and the composite secondary finished product that obtains of additional raw meal opisthosoma.
Described seaweed additional raw material is large-scale green alga, sargassum, Enteromorpha, sea lettuce or other algae.
Described steps d adds the dilution water body in additional raw material defibrination, making the solid content that obtains the algae slurry at last is 20%～30%; Above-mentioned algae slurry was deposited 1～2 day, carried out degradation treatment; The back adopts 80～100 purpose filters to filter, and obtains can be used for spray-dired algae slurry; Carry out spray-drying at 180 ℃～200 ℃, pulverize again, obtain 150 orders～200 purpose additional materials body of powder.
Above-mentioned dilution water body is the immersion water of the sea-tangle obtained in the tangleweed plant process, undaria pinnitafida, Enteromorpha, sea lettuce etc.
The percentage by weight of above-mentioned primary raw material body of powder and the composite mixing of additional raw meal opisthosoma is: primary raw material body of powder 90%～50%, additional raw meal opisthosoma 10%～50%.
The present invention does not add the nuisance free feed of any artificial hormone, and production cost is low, has both cleared up sea rubbish, has reduced environmental pollution again, for natural algae provides new approach in the development and use of domestic animal field of animal feed, can produce bigger economic results in society.
