Abstract
The invention provides a preparation method for grass carp feed. The preparation method includes the following steps of 1, raw material weighing; 2, raw material smashing, wherein raw materials weighed in the step 1 are added into a smashing cavity through a smashing machine, and then 50-80 parts of water is added for 15-30 min of smashing; 3, material homogenizing, wherein the materials smashed in the step 2 are conveyed into a homogenizer to be homogenized for 20-30 min; 4, material drying, wherein the materials homogenized in the step 3 are conveyed into a freeze drier to be freeze-dried, and the grass carp feed is obtained. According to the method, the materials are strictly selected and reasonably matched; all the raw materials for preparing the feed are smashed, homogenized and freeze-dried, so that the breakage rate and powder content of the obtained feed are reduced, the loss of nutritive substances is reduced, the quality of the feed is improved, and the cost of the raw materials is reduced.
Description
Technical field
The present invention relates to technical field of aquaculture, particularly to feedstuff used for aquiculture, be specifically related to a kind of Ctenopharyngodon idellus
The preparation method of feedstuff.
Background technology
Along with feed industry and the development of livestock breeding industry, high-quality pellet is increasingly favored by market,
Particularly in culture fishery, the demand of high-quality, the aquatic feeds of high remuneration is also constantly being risen, feed manufacturing emterprise
Also feed quality will be improved as the target constantly pursued.When pellet has comprehensive nutrition, good palatability, shortening are searched for food
Between, avoid particular about food, be readily transported, take care of, raise the series of advantages such as mechanization, the ratio in feedstuff total amount is continuously increased.
Pellet also exists certain problem in quality, is mainly manifested in: 1, feed nutrition is unbalanced and feedstuff cost high,
2, finished feed is broken, high containing powder rate, product is in water stability difference etc..Research shows, crude fibre suitable in feedstuff contains
Amount can improve the palatability of feedstuff, promotes to ingest, and improves the caking property of pellet, strengthens the stability in water, reduces battalion
Form the effects such as molten mistake point in water, but crude fibre makes its usage amount be restricted because of its problem being difficult to digest, so,
In order to make feedstuff utilization rate reach optimum level, it is generally the case that low thick fine of wide material sources in feedstuff, price can be reduced
The addition of the feedstuff that dimension hplc is high, increases the high protein content of price and the amount of the high feedstuff of fat content, this
Sample, not only causes the increase of feed cost, and crude fiber content suitable in feedstuff is conflicting with efficiency of feed utilization, when raising
When crude fiber content is the most suitable in material, then efficiency of feed utilization can be caused low, then can cause when crude fiber content is low in feedstuff raising
The increase of material cost, has an effect on the exterior quality of feedstuff simultaneously, makes feedstuff broken, high containing powder rate, poor at water stability.On
Situation of stating both had weakened the market competitiveness of enterprise, result in again the decline of Business Economic Benefit.
One notification number is CN101991027A, discloses the patent of invention of entitled feed of grass carp and preparation method thereof,
The feed of grass carp of this patent be by wheat-middlings, oil cake of flax seed, Zein powder, root of Cornu Cervi Pantotrichum, corn germ cake, bean cake, cottonseed meal, rapeseed cake,
Fish flour, dalcium biphosphate, choline chloride 50%, bentonite, fat emulsifier, Ctenopharyngodon idellus premix material and VE cooperation form.This invention
Being arranged by strict material choice and rational formula, it is balanced in nutrition, comprehensive, with strong points, have good attractant,
Stability, is greatly improved the speed of growth improving Ctenopharyngodon idellus, the generation of prevention grass carp disease.Analysis goes feed ingredient to understand, should
The protein raw material feedstuff that in feedstuff, price is high and fat material content are more, and the high raw material of crude fiber content is less, although
Improve efficiency of feed utilization, but feed cost is higher, and feedstuff is broken, high containing powder rate.Thus, greatly limit pellet
The development of industry.
Summary of the invention
It is an object of the invention to provide the preparation method of a kind of feed of grass carp, the method strictly selects materials, reasonably combined, will
After each raw material pulverizing of composition feedstuff homogenizing lyophilization process so as to get the percentage of damage of feedstuff and reduce containing powder rate, battalion
Support material damage to reduce, improve the quality of feedstuff, reduce cost of material.
For solving above-mentioned technical problem, the present invention is achieved through the following technical solutions.
The preparation method of a kind of feed of grass carp, comprises the steps:
(1) raw material weighs: weigh wheat-middlings 10～15 parts, fish flour 10～15 parts, wheaten starch 5～10 parts, bean cake 10～15 parts, dish
Seedcake 10～15 parts, barley bran 15～25 parts, Testa Tritici 15～25 parts, Folium Pini 2～5 parts, humic acid 3～5 parts, cellulase
0.3～0.6 part, premix material 0.5～1 part；
(2) raw material pulverizing: use pulverizer the raw material that above-mentioned steps (1) weighs is joined in crushing chamber, be subsequently adding 50～
Broken 15～30 minutes of 80 portions of pigment；
(3) material homogenizing: the material after middle for step (2) pulverizing is delivered to homogenizer homogenizing 20～30 minutes；
(4) dry materials: the material after homogenizing in step (3) is delivered to lyophilization in freezer dryer and i.e. obtains Ctenopharyngodon idellus and raise
Material.
Described cryodesiccated method is as follows: first by material pre-cooling 4 hours under the conditions of-3 DEG C, then by the thing after pre-cooling
Quick freezing in storehouse of freezing at material proceeds to rapidly-40 DEG C is-30～-40 DEG C to material center temperature, is then placed in condenser temperature
For-50 DEG C, vacuum be 20～30Pa dryness storehouse in freeze 2 hours, after freezing under the conditions of 55 DEG C sublimation drying 20 hours,
Dried material when being 25～15 Pa, is delivered from godown by the last pressure that is dried to dryness storehouse under the conditions of temperature is 65 DEG C.
Described premix material includes the following compositions of following weight parts: compound vitamin 1～3 parts, composite mineral matter 3～6 parts,
System health 60～75 parts.
