2) pig blood 2.2%, 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 water peanut 10%, earthworm powder 6.28%, fish meal 6%, fly maggot powder 5%, egg pupa Powder 4%, after glycine betaine 0.06%, bile salt 0.01%, wheat-middlings 12%, cassava fecula 5% carries out secondary mixing, through vibration discharger Discharging falls into autoclave quality-adjusting device and is passed through 62 DEG C~66 DEG C of steam, and mixing is quenched, after being kept for 13~17 minutes, into post curing It is crushed again through micronizer after drying machine is dry, smashing fineness is greater than after 190 mesh through 45 degree of inclination dischargings of helix emptying machine again Enter the adjustable screw blade formula quality-adjusting device of barrel temperature through dextrorotation variable-pitch auger feeder, add 24~25% moisture, 80 DEG C~85 DEG C at a temperature of carry out quenched 32~38 seconds after, through screw blade formula retainer 75 DEG C~85 DEG C at a temperature of The sterilization of curing in 100~200 seconds is kept the temperature, single screw rod is fed by bulking machine feed hopper by dextrorotation variable-pitch auger feeder and is squeezed Bulking machine carries out extrusion, and swelling granular density domination is in 550~600kg/m3, the die hole of the single screw squeezing expansion machine Diameter is Φ 2, and draw ratio 2, for the bulking machine feed hopper gradient greater than 72 degree, two sides are symmetrically each provided with a gas butterfly, The secondary mixing opens greatly two-door mixing machine, hammer crusher described in step 1) and step 2, Verticle grinding using oar blade type Machine, micronizer discharge port be all rectangular or rectangle, be connected separately with that one section of 30mm~130mm high is rectangular or rectangle The other end of changeover portion, changeover portion is just connect with respective lower road equipment, and the one side of the changeover portion is both provided with band fire extinguishing The safety plate of device, 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 In the double belt drying machines of the cross-flow type of rate control module after conical air duct is dry, 3% fish is sprayed with continous way roller spray machine For oil by vibration separation screen after turnover panel cooler is cooling, screening gained finished product carries out packing stacking, each in the processing step Dust pelletizing system is equipped at a charging and discharging, the dust pelletizing system is provided with pressure relief opening, and will let out using elongnated building conduit Pressure mouth leads to outdoor, and the length of the elongnated building conduit is less than 3m, cannot have in the setting of elongnated building conduit scene small In 138 degree of turning.
2. a kind of crab feed processing technology 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 crab feed processing technology 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 crab feed processing technology according to claim 1, which is characterized in that the swelling granular density uses Density controller control.
5. a kind of crab feed processing technology according to claim 1, which is characterized in that adopt autoclave quality-adjusting device inner cavity Use stainless steel material.
