Description

A kind of trout feed production method
Technical field
The present invention relates to aquatic feeds fields, and in particular to a kind of trout feed production method.
Background technique
Trout meat thorniness is few, Fresh & Tender in Texture, and smoother taste is full of nutrition, to have been favored by people, trout cultivation by It is formed on the development of trout feed production technology, trout feed is a kind of slow sinking feed, production technology production currently on the market Trout feed existing for main problem be: cost of material is high, efficiency of feed utilization is low, and generates a large amount of dust but in production process There is no explosion precaution, there are security risks；Trout is poor to general plant feed digestibility and utilization ability, affects nutriment It digests and assimilates, how to reduce cost of material using plant and nutrition equilibrium, suitable trout feeding habits can be produced and be conducive to digestion and inhale The trout feed of receipts is a problem to be solved.
Summary of the invention
The purpose of the present invention is to solve above-mentioned technical problems, provide a kind of trout 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 trout 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.
It is provided by the invention the specific scheme is that

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, is equipped with dust pelletizing system, the dust pelletizing system setting at each charging and discharging in the production method steps There is pressure relief opening, and pressure relief opening is led to by outdoor using elongnated building conduit, the length of the elongnated building conduit is less than 3m, institute State the turning that cannot have in the setting of elongnated building conduit scene less than 138 degree.
2. a kind of trout 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 trout 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 trout 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 trout feed production method according to claim 1, which is characterized in that adopt autoclave quality-adjusting device inner cavity Use stainless steel material.
