Description

A kind of salmon feed production method
Technical field
The present invention relates to aquatic feeds fields, and in particular to a kind of salmon feed production method.
Background technique
Astaxanthin rich in salmon, astaxanthin are a kind of strong anti-oxidation substances, possess anti-aging effect.Together When, astaxanthin also has effects that the effect of removing the injury of sunlight middle-ultraviolet lamp and inhibiting melanin, eats of salmon more, can It helps women to repair the skin to come to harm, skin is allowed to shine whitening brilliance again, thus salmon has been favored by people, salmon Fish culture is limited by the development of salmon Feed Production Technology, and salmon feed is a kind of slow sinking feed, production currently on the market Main problem existing for the salmon feed of method production is: cost of material is high, efficiency of feed utilization is low, and generates in production process big Dust is measured but without explosion precaution, there are security risks；Salmon is poor to general plant feed digestibility and utilization ability, affects battalion The digestion and absorption of substance is supported, how to reduce cost of material using plant and nutrition equilibrium can be produced, be suitble to salmon feeding habits and benefit It is a problem to be solved in the salmon feed of digestion and absorption.
Summary of the invention
The purpose of the present invention is to solve above-mentioned technical problems, provide a kind of salmon feed production method, utilize original The complementation of material makes original by secondary quenched, mixing, maturation process accordingly matched smashing fineness and suitable temperature, moisture Material reaches the glutinous degree of most good soft, prepares that nutrition is balanced, palatability is good, feed system by extrusion and unique auxiliary process The low feed of number, yields is high, abundant raw material, cheap, select everywhere can target-seeking plant as basic raw material, be greatly reduced Cost of material, but nutrition is balanced for resulting salmon feed, and feeding effect is good, has good diseases prevention, promotes digestion, And improve efficiency of feed utilization, reduce residual bait, water quality is improved, ultramicro grinding process is eliminated in production method, further Production cost is reduced, is controlled by refining temperature etc., product effect but has same effect, and production method of the invention With explosion prevention function, the hidden danger of dust explosion in Feed Manufacturing is prevented.

2) pig blood 0.2%, dandelion 0.26%, purslane 0.25%, brewex's grains 3%, are used into hammer leaf powder after cleaning screen clears up impurity elimination Broken machine crushes to obtain raw material and first step gained raw material and corn flour 6%, earthworm powder 0.28%, fish meal 23%, egg pupa powder 4%, greatly After beans lecithin 3%, bile salt 0.01%, wheat-middlings 8%, cassava fecula 10% carries out secondary mixing, fallen through vibration discharger discharging Enter autoclave quality-adjusting device and be passed through 62 DEG C~66 DEG C of steam, mixes quenched, keep 18~after twenty minutes, into after-ripening fluidized dryer Crushed again through vertical crusher after drying, smashing fineness be 90~100 mesh after through helix emptying machine be discharged again through dextrorotation varying pitch Scroll feeder enters the adjustable screw blade formula quality-adjusting device of barrel temperature, adds 25~26% moisture, at 82 DEG C~87 DEG C At a temperature of carry out quenched 32~38 seconds after, through screw blade formula retainer 78 DEG C~88 DEG C at a temperature of heat preservation 100~200 Second curing sterilization, feeds single screw squeezing expansion machine by bulking machine feed hopper by dextrorotation variable-pitch auger feeder and is squeezed Extruding is pressed, at 123~140 DEG C, pressure control produces extruding product in 33~36kg/cm2, the extruding for temperature control before depanning In 470~570kg/m3, the die throat diameter of the single screw squeezing expansion machine is Φ 1.8 for grain density control after object depanning, Draw ratio is 1.8, and the bulking machine feed hopper gradient is greater than 72 degree, and two sides are symmetrically each provided with a gas butterfly, the list spiral shell The speed of mainshaft of bar extruder is 500~550rpm, and the secondary mixing opens greatly two-door mixing machine, step using oar blade type 1) and hammer crusher described in step 2, vertical crusher, micronizer discharge port be all rectangular or rectangle, connect respectively It is connected to that one section of 30mm~130mm high is rectangular or the changeover portion of rectangle, the other end of changeover portion just connects with respective lower road equipment It connects, the one side of the changeover portion is both provided with the safety plate with extinguishing device, and another plane of symmetry, which is both provided with, leads to outdoor Pilot safety plate and pipeline；
3) puffed material obtained by step 3) is transported to through self-cleaning type bucket elevator, and is arranged in high-rise included evaporation and aqueous Through vibration separation screen after conical air duct is dry in the double belt drying machines of the cross-flow type of rate control module, screening gained finished product into Row is packaged stacking, and the charging angle of the self-cleaning type bucket elevator is 55 degree, each charging in the production method steps With dust pelletizing system is equipped at discharging, the dust pelletizing system is provided with pressure relief opening, and is drawn pressure relief opening using elongnated building conduit To outdoor, the length of the elongnated building conduit is less than 3m, cannot have in the setting of elongnated building conduit scene less than 138 degree Turning.
2. a kind of salmon feed production method according to claim 1, which is characterized in that the dust pelletizing system is using configuration Circle transition conduit, the circle is arranged in the pulse bag type dust collector of antistatic filter bag, the ejection air port of the pulse bag type dust collector Transition conduit other end and blower direct connection, the blower direct connection have muffler, and the muffler is horizontal positioned, the round coupling tube Length is not more than 0.8m.
3. a kind of salmon feed production method according to claim 1, which is characterized in that the dextrorotation variable-pitch auger is fed Glassware installs gradient no more than 10 °.
4. a kind of salmon feed production method according to claim 1, which is characterized in that the particle of the extruding product is close Degree is controlled using density controller.
5. a kind of salmon feed production method according to claim 1, which is characterized in that adopt autoclave quality-adjusting device inner cavity Use stainless steel material.
