When the Misgurnus auguillicaudatus special compound feed is fed, if its subsidence velocity is too fast, it is easy to happen feed
Due to being difficult to sufficiently to be ingested by Misgurnus auguillicaudatus the phenomenon that be deposited on cultivation bottom of pond portion, lead to the waste of feed, while also right
Water body causes certain pollution.To solve the above-mentioned problems, present invention further propose that a kind of big squama pair mud as described above
The preparation method of loach special compound feed is prepared the Misgurnus auguillicaudatus special compound feed by way of extrusion
The pollution to water body is reduced to improve the utilization rate of feed at the extremely slow floating forage of subsidence velocity, Fig. 1 is shown
One embodiment of the preparation method of Misgurnus auguillicaudatus special compound feed provided by the invention.Referring to Fig. 1, in the present embodiment
In, the preparation method of the Misgurnus auguillicaudatus special compound feed the following steps are included:
Step S10, fish meal, steck powder, corn protein powder, dregs of beans, rapeseed meal, corn protein powder, Strong flour, di(2-ethylhexyl)phosphate are taken
Then hydrogen calcium, choline chloride and premix mixing carry out primary comminution and form just mixing；
In the present embodiment, step S10 is more preferably: taking fish meal, steck powder, corn protein powder, dregs of beans, rapeseed meal, high muscle
Then flour, calcium dihydrogen phosphate, choline chloride and premix mixing carry out primary comminution and cross point that aperture is 1.0~1.5mm
Grade sieve forms just mixing.By way of grinding and sieving, so that the particle diameter distribution in the obtained just mixing is more equal
Even, the oversize after sieving can be again by being sieved after primary comminution, and it is 1.0 that all raw materials are all sufficiently ground into partial size
The powder of~1.5mm.Wherein, the primary comminution can by the grinding mode of the routine such as high speed disintegrator or grinding into
Row, carries out preferably by high speed disintegrator, has the advantages that easy to operate, time saving.
Step S20, the just mixing is pulverized, forms Ultramicro-powder particle；
Ultramicro grinding refers to overcomes solid interior cohesiveness to be allowed to broken using mechanical or hydrokinetic method, thus will
The material particles of small particle are crushed to the operating technology of the smaller ultramicro powder of partial size, have crush speed it is fast, can be at low temperature
Progress, finished product grain size is thin and is evenly distributed, improves the advantages that raw material availability and saving raw material, and mill can be selected to be situated between when in use
Formula, air-flowing type or mechanical shearing type micronizer carry out, wherein the parameter setting of the micronizer belongs to existing skill
Art can obtain the crushed material with different-grain diameter size by relative parameters setting, and this will not be repeated here.
In the present embodiment, step S20 further includes the steps that crushed material is sieved in the specific implementation, specific embodiment
Are as follows: the just mixing is carried out pulverizing and crossing the classifying screen that aperture is 0.1~0.3mm, forms Ultramicro-powder particle.In this way,
The partial size of the Ultramicro-powder particle obtained is in 0.3mm hereinafter, be conducive to improve obtained feed in Misgurnus auguillicaudatus body
Interior digestion and absorption.
Step S30, extrusion again after modifier treatment is carried out to the Ultramicro-powder particle, pellet is made；
Animal feed is pelletized again after usually all carrying out modifier treatment to powder made of raw material during the preparation process, usually
For steam regulation of texture, conditioning of texture, following purposes may be implemented by modifier treatment: (1) making material under hydrothermal, the gelatinization degree of starch is big
Amplitude increases, while also promoting the protein receptor thermal denaturation in material, and the albumen of denaturation is easy to be digested, to improve particle
The digestive utilization ratio of feed；(2) most of pathogenic bacteria, such as Escherichia coli and salmonella etc. are killed, keep feed hygiene horizontal
It is guaranteed；(3) pass through the sticky component gelatinized starch, denaturation by the hydrothermal of steam, in material during quenched
Albumen can give full play to the effect of binder, can effectively bond periphery others component, under the squeezing action of pressing mold pressure roller,
Particle and particle be combined with each other more closely, so that pellet be made to become more densely cross-linked, appearance is bright and clean, during the feeding process
It is not easy to be increased stability in water by moisture attack；(4) so that material is softened by quenched, more plasticity, with
In the extrusion process of die hole wall, pressing mold inner wall and pressure roller appearance, frictional force reduces, and avoids a large amount of mechanical in pelletization
Thermal energy can be changed into, while slowing down the abrasion of pressing mold and pressure roller, so as to save the energy consumption of granulation, improve granulator pressure
The service life of mould, pressure roller.In the present embodiment, the embodiment of the modifier treatment in step S30 are as follows: to the ultramicro grinding
The vapor that temperature is 95~105 DEG C, quenched 60~80s are passed through in material.And in actual process, the quenched place
The process of reason can carry out in quality controling machine, and the setting of technological parameter belongs to the prior art, can pass through steam pressure, addition
The control of the parameters such as amount, so that the material after quenched reaches certain water content, this will not be repeated here.
Extrusion pressing puffing process described in step S30 can carry out in extruder, and the extruder is selected
Single screw squeezing expansion machine or twin-screw extruder etc. are selected double in the present embodiment with the extruder
It is illustrated for screw extrusion machine, the specific embodiment of the extrusion in step S30 are as follows: modifier treatment will be passed through
The Ultramicro-powder particle afterwards is sent into twin-screw extruder and carries out extrusion, wherein the work of the extruder
Make parameter are as follows: 220~240rpm of screw speed, the temperature of feed zone, extruded segment and discharging section correspond to 95~100 DEG C, 116~
120 DEG C, 131~140 DEG C.
It is understood that cooling device and cutter device can also be set in the downstream of the extruder, it will
It cuts and is granulated after the material squeezed out from the discharge port of the extruder is cooling, granular feed of swimming is made, wherein institute
The cooling device of water cooling or the forms such as air-cooled can be selected by stating cooling device, and when selection can be according to the actual conditions of production line
Selected, it is not limited here, and the cooling device and cutter device selection and parameter setting belong to this field
The prior art, such as the cutter device cut be granulated when, the size of feed can be wanted according to when actual production
It asks to adjust the revolving speed of cutter device, with the corresponding granulated meal for obtaining different sizes, this will not be repeated here.
Step S40, soya-bean oil will be sprayed after pellet drying, Misgurnus auguillicaudatus special compound feed is made.
In step s 40, the drying can select the forms such as heated-air drying, microwave drying or fluidized drying, and correspondence is adopted
It is carried out with blast drier, microwave dryer or fluid bed dryer, it is not limited here.It will be by made from extrusion
Graininess is swum after feed drying, and soya-bean oil is sprayed at the pellet surface, can be prepared by the dedicated cooperation of Misgurnus auguillicaudatus
Feed.It is understood that since the technique of spraying soya-bean oil is typically all to carry out under heating or hot conditions, so spraying
After soya-bean oil, the step of being cooled to room temperature feed is also typically included.And in order to enable the dedicated cooperation of obtained Misgurnus auguillicaudatus
Feed size size in feed product is more uniform, can also include the steps that screening after cooling, is cut with screening out part
