Abstract
The invention discloses an aquaculture fodder formula; a method includes the following steps: (1) raw material selection, (2) mixing and crushing, (3) conditioning processing, (4) extrusion expanding granulation, (5) granules post-processing, and (6) fodder forming. A water-resistant aquaculture fodder prepared by the method has the particle size of 1.0-3.0 mm, has half-floating performance, and is not broken up and decomposed when soaked in water for more than or equal to 12 h. According to the invention, the operation is simple and convenient, and the preparation technology is simple; and the prepared aquaculture fodder has the half-floating performance, can meet the predation requirements of aquatic organisms in different water-area depths, has long water-resistant time, has the resolving time in water being about 12 h, effectively avoids a phenomenon that the aquaculture fodder is scattered and resolved in water before being eaten, increases the fodder utilization rate, and improves the cultivation water quality.
Description
Technical field
The present invention relates to the field that aquaculture feed manufactures, particularly relate to the aquaculture feed formula that a kind of resistance to water is high.
Background technology
Culture fishery mainly promotes the growth of aquatic biological in the mode of feed of throwing something and feeding, material is dispersed in water after throwing something and feeding, and aquatic biological is found one by one and eaten, there is feed used for aquiculture miscellaneous in the market, there is floating type, sedimentation type, improve aquatic organism disease-resistant performance etc., but these feeds mostly poor water resistance, after staying for some time in water, also do not wait prey, just dissolve, defeated and dispersed in water body, this makes the feeding volume of feed increase on the one hand, waste resource, on the other hand, a large amount of feeds is dissolved in water body, the eutrophication of water quality can be caused, make microorganism undue growth and breeding in water, microorganism absorbs the dissolved oxygen in water in a large number, cause fish because of anoxic death by suffocation, be unfavorable for the sound development of culture fishery.
Summary of the invention

(2) co-grinding: described each raw material mixer mixing is uniformly dispersed, then proceeds in pulverizer and carry out 3 ~ 4 grades of pulverization process;
(3) modifier treatment: input in expanded quality-adjusting device by the mixed material after co-grinding in step (2), modified 3 ~ 5min at 95 DEG C, makes the water content of material be 20 ~ 25%;
(4) extrusion granulation: adopt single screw extrusion machine to carry out extrusion granulation to the mixed material after modified in step (3), described extrusion granulation process parameters is: swelling temperature 110 ~ 120 DEG C, extrusion temperature 85 ~ 90 DEG C, rate of extrusion 35 ~ 40 turns/min;
(5) pellet post processing: the pellet after extrusion in step (4) is proceeded in stable quality-adjusting device, inside holding modifier treatment 25 ~ 35min at 60 ~ 75 DEG C;
(6) feed is shaping: the feed granules through post processing in step (5) is proceeded to cool drying 20 ~ 25min in cold air drying sifting bed, and the water content making feed is 15 ~ 20%, obtains resistance to water aquaculture feed.
Preferably, described starch is at least one in wheaten starch, cornstarch and farina.
Preferably, in described step (2), the mixed material fineness after described pulverization process is 20 ~ 28 orders.
Preferably, in described step (4), the feed particle diameter after described extrusion is 0.8 ~ 3.5mm.
Preferably, in described step (6), the sieve diameter of described cold air drying sifting bed is 0.5 μm.
Preferably, in described step (6), described cold air drying technique parameter is: temperature 30 ~ 40 DEG C, air quantity 5 ~ 10m
3/ min.
The technology of the present invention beneficial effect:
The formula of a kind of aquaculture feed of technical solution of the present invention, simple to operation, preparation technology is reasonable, prepared aquaculture feed has half sink-float, can meet the hydrobiological predation demand of different Larger water depths, and water resisting time is long, resolving time in water is about 12h, dissolved defeated and dispersed phenomenon in water body before effectively prevent predation, improve the utilization rate of feed, improve cultivation water.
Detailed description of the invention
