Description

A kind of slow falling fish feed and its preparation process
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
1. just crushing：Fish meal, dregs of beans, cornstarch, alphalise starch, multi-vitamins, composite mineral matter and lactose is taken to crush respectively, Cross 50 ~ 80 mesh screens；
2. separating twice：Take the fish meal after the first crushing of formula ratio, dregs of beans, cornstarch, alphalise starch, multi-vitamins, compound The vegetable oil of formula ratio, mixing is added in minerals and lactose, mixing, and separating twice crosses 80 ~ 100 mesh screens；
3. pelletizing：By after separating twice mixture expanding treatment or compressing tablet process；
4. post-processing：It is dried at 40 ~ 45 DEG C, is placed in cooling at 25 ~ 28 DEG C, obtains compound mixed feed；
（2）Preparation for spraying the lotion for forming slow falling film
1. crushing：Maltodextrin, starch from sweet potato, sodium bicarbonate, ethylene-vinyl acetate copolymer, citric acid, chlorination are taken respectively Sodium and P123 type PEO-PPO-PEO block copolymers crush, and cross 80 ~ 100 mesh screens；
2. the processing of sodium bicarbonate：The starch from sweet potato of formula ratio is taken, water is added, is uniformly mixing to obtain paste, formula ratio is added Sodium bicarbonate roll on it, paste is coated into sodium bicarbonate, is dried at 80 ~ 85 DEG C, be placed at 25 ~ 28 DEG C it is cooling, Obtain sodium bicarbonate particle；
3. the preparation of lotion：The ethylene-vinyl acetate copolymer after the crushing of formula ratio is taken, water is added, stirs evenly, is added Lemon acid, sodium chloride and P123 type PEO-PPO-PEO block copolymers are added maltodextrin and stir evenly after stirring evenly；It is eventually adding carbonic acid Hydrogen sodium particle, spray treatment is walked under entering without stir process and in 5min；
（3）A kind of preparation of slow falling fish feed：By for spraying the Emulsion Spraying for forming slow falling film outside compound mixed feed, One layer of slow falling film is formed outside compound mixed feed, the thickness control of slow falling film is 1.0 ~ 1.5mm；It dries, is placed at 40 ~ 45 DEG C It is cooling at 25 ~ 28 DEG C, obtain a kind of slow falling fish feed.
In conclusion the invention has the advantages that：
The compound use that the compound mixed feed of slow falling type is combined by slow falling film, greatly slows down the sinking speed of feed, reduces Feeding time, reduction feed cost；Feed conversion rate is high, and cost substantially reduces, environmental protection and energy saving.
