Description
Technical field
The present invention relates to a kind of fishing mixed 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..
The mixed feed of the prior art is made of multicomponent, the speed that is disintegrated when settling in water, different component it
Between binding force there is a possibility that rupture, cause fish that can not absorb the whole nutrition of feed.
Invention content
The first object of the present invention is to provide a kind of fishing mixed feed, has and extends the excellent of disintegration effective feed time
Point.
The present invention above-mentioned technical purpose technical scheme is that：
A kind of fishing mixed feed, including compound mixed feed and one layer of release membranes being sprayed on outside compound mixed feed, delay
The thickness for releasing film is 0.3 ~ 0.5mm；By mass, for spray formed release membranes lotion include nano-calcium carbonate 10.5 ~
11.2%, lactose 8.3 ~ 8.6%, carboxymethyl cellulose 6.0 ~ 6.3%, polyvinyl alcohol 6.6 ~ 7.0%, polyacrylic acid 5.2 ~ 5.5%, poly-
Allylamine hydrochloride 3.2 ~ 3.4%, neopelex 1.3 ~ 1.5%, vitamin C 0.3 ~ 0.5%, polyethylene glycol 1.3 ~
1.5% and ethyl alcohol 10.2 ~ 10.5%.
In one layer of release membranes of compound mixed feed trypsin method, when feed enters in water, water first acts on the film, and water is first
It is swollen or is gradually dissolved the filmogen on this layer, slows down the time that water acts on compound mixed feed, plays the effect of sustained release
Fruit has the time for extending and being disintegrated effective feed, and the possibility of feed entirety nutrition can not be absorbed by reducing fish caused by feed disintegration
Property.
Further preferably：By mass, for spraying, to form the lotion of release membranes further include 2.1 ~ 2.3% He of naphthenic oil
Glycerine 3.3 ~ 3.5%.
Further preferably：The release membranes trypsin method has one layer of slow falling film, and the thickness of slow falling film is 1.0 ~ 1.5mm；With
It includes 15.0 ~ 16.5wt% of maltodextrin, 5.0 ~ 5.5wt% of starch from sweet potato, sodium bicarbonate 8.5 to form the lotion of slow falling film in spraying
~ 10.0wt%, 8.0 ~ 10.0wt% of ethylene-vinyl acetate copolymer, 4.0 ~ 4.5wt% of citric acid, 2.0 ~ 2.5wt% of sodium chloride and
P123 type 3.0 ~ 3.3wt% of PEO-PPO-PEO block copolymers, the starch from sweet potato are coated on outside sodium bicarbonate.
In one layer of slow falling film of release membranes trypsin method, when the feed enters in water, water body gradually wraps up slow falling film, is dispersed in second
Water-soluble material in the hydrophobic materials such as alkene-vinyl acetate co-polymer gradually dissolves, and hydrophobic starch from sweet potato is acted in water
It gradually scatter down to release the sodium bicarbonate being wrapped in it, sodium bicarbonate and citric acid react release outlet in water
Body pushes compound mixed feed to roll to slow down the sinking of feed in water；Simultaneously because starch from sweet potato, sodium chloride and wheat
The effect of bud dextrin can improve the feed physical properties such as salinity, concentration of water body nearby, to further slow down under feed
It is heavy；After compound mixed feed is absorbed, remaining slow falling film can be in P123 type PEO-PPO-PEO block copolymers and chlorine in water
Change and dissolved under the collective effect of sodium, 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 is formed through tabletting.
After compressing tablet process, the specific surface area of feed reduces, and density increases, and causes feed sedimentation to become faster, with the prior art
Mode is the feed that can not be handled in this case, but can also be obtained on the feed after compressing tablet process using the present processes
Similar effect, simultaneously because the stability of tabletting feed, can greatly improve safety, the stability of product, be conducive to
Industrialized production.
Active force after tabletting between feed increases, and can greatly increase disintegration time limited.
