Description
Technical field
The present invention relates to a kind of slow falling fish feed and its preparation processes.
Background technology
Fish feed is the basic substance or input of aquaculture.Quality of the fodder and quantity are directly related to China
The development of culture fishery, the especially environmental protection to the control of aquaculture cost, culture efficiency and Cultivated water.Therefore,
Solution and the production and application for grasping fish feed, science decision are great to promote the sustainable health development of culture fishery to have
Meaning.
The Chinese patent that Authorization Notice No. is CN102293347B, authorized announcement date is on January 30th, 2013 discloses one
Kind powdery compound feed for sturgeons comprising fish meal, pre-gelatinized starch, expanded soybean, fermented bean dregs, fish oil, brewer's yeast, beans
Oil, minerals, choline chloride, calcium dihydrogen phosphate etc..
When the mixed feed of the prior art is launched, due to gravity, mixed feed rapid subsidence to bottom causes fish
It can not bite in time, cause the waste of feed.
Invention content
The first object of the present invention is to provide a kind of slow falling fish feed, has the advantages that slow down sinking speed.
The present invention above-mentioned technical purpose technical scheme is that:
A kind of slow falling fish feed, including compound mixed feed and one layer of slow falling film being sprayed on outside compound mixed feed, slowly
The thickness of heavy film is 1.0 ~ 1.5mm;For spray formed slow falling film lotion include 15.0 ~ 16.5wt% of maltodextrin, sweet potato form sediment
5.0 ~ 5.5wt% of powder, 8.5 ~ 10.0wt% of sodium bicarbonate, 8.0 ~ 10.0wt% of ethylene-vinyl acetate copolymer, citric acid 4.0 ~
4.5wt%, sodium chloride 2.0 ~ 2.5wt% and P123 3.0 ~ 3.3wt% of type PEO-PPO-PEO block copolymers, the starch from sweet potato packet
It overlays on outside sodium bicarbonate.
In one layer of slow falling film of compound mixed feed trypsin method, when the slow falling fish feed enters in water, water body gradually wraps up
Slow falling film, the water-soluble material being dispersed in the hydrophobic materials such as ethylene-vinyl acetate copolymer gradually dissolve, and hydrophobic is red
Sweet potato starch gradually scatter to release the sodium bicarbonate being wrapped in it under water effect, and sodium bicarbonate and citric acid are in water
Middle reaction releases gas, and compound mixed feed is pushed to roll to slow down the sinking of feed in water;Simultaneously because sweet potato is formed sediment
The effect of powder, sodium chloride and maltodextrin can improve the feed physical properties such as salinity, concentration of water body nearby, thus into one
Step slows down the sinking of feed;After compound mixed feed is absorbed, remaining slow falling film can be in P123 types PEO-PPO-PEO in water
It is dissolved under the collective effect of block copolymer and sodium chloride, the usual nutrition as fish is used.
Further preferably:Compound mixed feed includes 47.7 ~ 48.5wt% of fish meal, 19.0 ~ 19.5wt% of dregs of beans, corn shallow lake
It is 10.0 ~ 10.5wt% of powder, 10.0 ~ 10.5wt% of alphalise starch, 3.5 ~ 3.7wt% of vegetable oil, 0.3 ~ 0.5wt% of multi-vitamins, compound
5.5 ~ 6.0wt% of 2.3 ~ 2.5wt% of minerals and lactose, the nutrition of the compound mixed feed include crude protein 44.0 ~
45.0wt%, 12.0 ~ 12.5wt% of 10.0 ~ 10.2wt% of crude fat, 1.20 ~ 1.25wt% of crude fibre and coarse ash;It is described compound to match
It closes feed and is suitable for Acipenser sinensis juvenile fish.
Further preferably:Compound mixed feed forms or tabletting forms through puffing.
Expanding treatment can increase the specific surface area of feed, reduce density, to further slow down sinking speed.Tabletting
After processing, the specific surface area of feed reduces, and density increases, and causes feed sedimentation to become faster, is that can not locate in prior art manner
The feed of reason in this case, but similar effect can also be obtained on the feed after compressing tablet process using the present processes,
Simultaneously because the stability of tabletting feed, can greatly improve safety, the stability of product, be conducive to industrialized production.
The second object of the present invention is to provide a kind of preparation process of slow falling fish feed.
The present invention above-mentioned technical purpose technical scheme is that:
A kind of preparation process of slow falling fish feed, includes the following steps:
(1)The preparation of compound mixed feed
