Abstract
The invention provides a preparation method of aquatic puffed feed which is high in digestion rate in fishes, small in feed waste, high in stability in water and low in pollution to the water. The preparation method of the aquatic puffed feed comprises the following steps: removing impurities, coarsely crushing, mixing primarily and mixing secondarily, extruding and puffing via two screw rods, drying, uniformly coating grease, cooling and sieving stage by stage. The preparation method of the aquatic puffed feed is simple and reasonable in steps; the feed is coated with the grease, the sequent puffing process of the feed under the room temperature is reduced; the dissolving time of the feed in the water is prolonged.
Description
Technical field
The present invention relates to technical field of aquaculture, particularly a kind of preparation method of expanded feeds of aquaculture.
Background technology
Puffing aquatic product feed is a kind of feed having application prospect, and its main feature is that water stability is good, digestibility is high, feed waste is few, little to water pollution.In puffing process, feed is through the process of a HTHP in Builking cavity, forms a kind of particle of bulk porous.Puffing process can improve starch burn degree in feed, therefore compared with hard pellet diet, is easier to be digested and assimilated by aquatic livestock.Meanwhile, all right passivation ANFs of process of high temperature, high pressure, high shear force, kills the microorganism in raw material, improves product quality, increase product stability.And high-quality aquatic feeds be a kind of nutritious and balanced, containing antibiotic, good stability, green feed that absorption rate is high, this feed is less to the negative effect of cultivation water environment in aquaculture of aquatic animal process, to improving water quality, reduce body eutrophication and have significant effect, be conducive to promoting China culture fishery sustainable and stable development.
But this feeding quality is lighter, on can keeping afloat for a long time, even there is not the phenomenon of sinking, this makes the predation of the aquatic biological living in waters lower floor be restricted, raiser needs to execute simultaneously and feeds solid feed and expanded pellet diet, and process of feeding is loaded down with trivial details, and expanded pellet diet kicks the beam due to quality, the weather of wind is being had easily to be blown away, difficulty of feeding.
Summary of the invention
The object of the present invention is to provide that a kind of fish body digestibility is high, feed waste is few, water stability good, preparation method to the little expanded feeds of aquaculture of water pollution.
(1) by each component raw material impurity elimination cleaning, carry out coarse crushing, carry out mixed once in described ratio, obtain the thick batch mixing of raw material stand-by.
(2) thick for above-mentioned raw materials batch mixing is carried out ultramicro grinding, then with fish B B-complex, mineral feed supplement, calcium dihydrogen phosphate, stone flour, wheat bran, aquatic products is high temperature resistant, and enzyme carries out secondary in proportion mixes.
(3) raw material mixed is added water modified, make expanded pellet feed by twin-screw extruder.
(4) drying box post curing is placed in dry.
(5) carry out grease to expanded pellet diet to be coated with outward, grease is sprayed on expanded pellet diet equably.
(6) by expanded pellet diet cooling, classification, screening, pack, obtain finished product.
Concrete, the invention provides a kind of preparation method of expanded feeds of aquaculture, concrete preparation method is as follows:
(1) by each component raw material through impurity elimination cleaning, coarse crushing, by carrying out mixed once after 50 mesh sieves, obtain the thick batch mixing of raw material stand-by.
(2) thick for above-mentioned raw materials batch mixing is carried out ultramicro grinding, ultramicro grinding by 90 mesh sieves, then with set content fish B B-complex, mineral feed supplement, calcium dihydrogen phosphate, stone flour, wheat bran, aquatic products is high temperature resistant, and enzyme carries out secondary mixes.
(3) by step (2) obtain secondary mixed material evenly add 30% water carry out modified after, move into twin-screw extruder and carry out extrusion operation, screw speed is 50 ~ 70r/min, rate of feeding 30 ~ 50r/min, the feed zone of barrel zone temperature controls at 90 ~ 110 DEG C, interlude controls at 100 ~ 115 DEG C, and discharging section controls, at 110 ~ 125 DEG C, to make expanded pellet feed by twin-screw extruder.
(4) step (3) is obtained expanded pellet feed and be placed in drying box post curing drying, it is 65 ~ 70 DEG C that dry the temperature inside the box controls, and drying time is 4 hours.
(5) to step (4) obtain dry after expanded pellet feed expanded pellet diet carry out grease and be coated with outward, grease be coated with outward adopt spray into not higher than 3% rape oil, grease is sprayed on expanded pellet diet equably, and it is 85 ~ 90 DEG C that spraying temperature controls.
(6) expanded pellet diet after being coated with outward by grease, through cooling, classification, screening, packaging, obtains puffing aquatic product finished feed.
Beneficial effect of the present invention is, processing method of the present invention is simple, each processing step arranges rationally, the spraying of grease, reduce feed follow-up expansion process at room temperature, extend the dissolution time of feed in water, the good stability of feed in water, fish body digestibility be high, feed waste is few, little to water pollution.
