2) pig blood 0.2%, dandelion 0.2%, purslane 0.25%, brewex's grains 3%, are used into Verticle grinding after cleaning screen clears up impurity elimination Machine crushes to obtain raw material and first step gained raw material and corn flour 10%, earthworm powder 0.28%, fish meal 6%, egg pupa powder 4%, beet After alkali 0.06%, bile salt 0.01%, wheat-middlings 6%, cassava fecula 22% carries out secondary mixing, kettle is fallen into through vibration discharger discharging Formula quality-adjusting device is simultaneously passed through 62 DEG C~66 DEG C of steam, mix it is quenched, it is dry into after-ripening fluidized dryer after being kept for 13~17 minutes It is crushed again through micronizer afterwards, smashing fineness is fed through dextrorotation variable-pitch auger after being greater than 190 mesh through helix emptying machine discharge again Glassware enters the adjustable screw blade formula quality-adjusting device of barrel temperature, adds 23~26% moisture, in 80 DEG C~85 DEG C of temperature At a temperature of heat preservation curing in 100~200 seconds after quenched 32~38 seconds of lower progress, through screw blade formula retainer at 75 DEG C~85 DEG C Sterilization, by dextrorotation variable-pitch auger feeder by bulking machine feed hopper feeding single screw squeezing expansion machine squeeze it is swollen Change, swelling granular density domination is in 470~570kg/m3, the die throat diameter of the single screw squeezing expansion machine is 1~Φ of Φ 8, Draw ratio is 1.5~2, and the bulking machine feed hopper gradient is greater than 72 degree, and two sides are symmetrically each provided with a gas butterfly, described two Secondary mixing opens greatly two-door mixing machine, hammer crusher described in step 1) and step 2, vertical crusher, ultra micro using oar blade type The discharge port of pulverizer is all rectangular or rectangle, is connected separately with that one section of 30mm~130mm high is rectangular or the changeover portion of rectangle, The other end of changeover portion is just connect with respective lower road equipment, and the one side of the changeover portion is both provided with the guarantor with extinguishing device Dangerous piece, 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, is equipped with dust pelletizing system at each charging and discharging in the processing step, the dust pelletizing system, which is provided with, lets out Mouth is pressed, and pressure relief opening is led to by outdoor using elongnated building conduit, the length of the elongnated building conduit is less than 3m, described quick-fried There cannot be the turning less than 138 degree in fried venting conduit scene setting.
2. a kind of fresh water fish feed processing technology according to claim 1, which is characterized in that the dust pelletizing system, which uses, matches The pulse bag type dust collector of antistatic filter bag is set, circle transition conduit is arranged in the ejection air port of the pulse bag type dust collector, described Circle transition conduit other end and blower direct connection, the blower direct connection have muffler, and the muffler is horizontal positioned, the round transition Length of tube is not more than 0.8m.
3. a kind of fresh water fish feed processing technology according to claim 1, which is characterized in that the dextrorotation variable-pitch auger Feeder installs gradient no more than 10 °.
4. a kind of fresh water fish feed processing technology according to claim 1, which is characterized in that the swelling granular density is adopted It is controlled with density controller.
5. a kind of fresh water fish feed processing technology according to claim 1, which is characterized in that autoclave quality-adjusting device inner cavity Using stainless steel material.
