Cov dev yog omnivores, thaum miv yog cov tsiaj txhu nruj heev. Cov muaj pes tsawg leeg ntawm lawv cov khoom xyaw pub thiab lawv cov khoom noj khoom haus sib txawv heev, yuav tsum tau xaiv cov pellet zeb uas haum rau txhua hom tsiaj thaum tib lub sij hawm ua tau raws li qhov yuav tsum tau ua ntawm "siab fineness, zoo nutrient retention, thiab zoo heev palatability." Tshwj xeeb, peb qhov tseem ceeb yuav tsum tau xav txog:

Ua ntej, muab qhov tseem ceeb rau ntxaib - ntsia hlau dev noj zaub mov extruder tshuab nrog kev sib tsoo zoo. Cov khoom xyaw dev thiab miv feem ntau muaj feem ntau ntawm cov nqaij noj (feem ntau yog 30%-50%) thiab yuav tsum tau tov nrog txiv hmab txiv ntoo thiab zaub hmoov, probiotics, thiab lwm yam, yuav tsum tau pellet zeb sib tsoo precision ntawm 80{11}}120 mesh. Cov qauv tsim ntawm ntxaib - ntsia hlau qauv tso cai rau "sib tsoo ua ntej nthuav dav," qhov twg cov ntaub ntawv raw yog hauv av hauv ob theem (20 mesh hauv thawj theem thiab 80 mesh hauv qhov thib ob) ua ntej nkag mus rau hauv lub tshuab extrusion, xyuas kom cov pellets zoo yam tsis muaj coarse residue, haum rau lub plab zom mov ntawm dev. Tib -screw pellet mills tsis muaj kev sib tsoo txaus, yooj yim ua rau cov nqaij tsis sib xws, cuam tshuam rau palatability. Rau cov khoom noj miv, nws raug nquahu kom xaiv cov khoom siv nrog "tsawg-kub extrusion" muaj nuj nqi, tswj lub extrusion chamber kub ntawm 80-90 degree, 30-40℃qis dua cov khoom siv zoo tib yam. Qhov no ua rau kom muaj kev tuav pov hwm cov khoom noj uas muaj cua sov hauv cov nqaij qaib thiab ntses noj, thiab tiv thaiv kom tsis txhob muaj cov khoom xws li taurine.

Thib ob, xyuam xim rau kev teeb tsa ntawm ncej- txheej txheej seasoning. Cov dev thiab miv yog rhiab rau zaub mov tsw. Aub zaub mov extruders yuav tsum tau nruab nrog ib tug tshwj xeeb seasoning spraying ntaus ntawv. Tom qab cov pellets txias, roj nqaij qaib, roj ntses, los yog tsiaj - tshwj xeeb flavorings yog sib npaug zos rau saum npoo. Cov tshuaj tsuag tuaj yeem tswj tau los ntawm lub ntsuas dej ntws (0.5%-5%). Cov tshuab pellet zoo ib yam tsis muaj qhov ua haujlwm no, thiab kev siv tshuaj tsuag tuaj yeem yooj yim ua rau tsis sib xws, nrog qee cov pellets clumping vim muaj roj ntau dhau. High-end tsiaj pellet tshuab txais kev tsim qauv ntawm "atomized txau + cua kub kho." Lub atomizing nozzle atomizes lub seasoning rau qis dua 10μm, kom ntseeg tau tias txhua pellet yog sib npaug coated nrog tsw. Tom qab ntawd, 60℃cua kub sai kho qhov tsw, tiv thaiv tsw poob thaum lub sijhawm thauj mus los. Tsis tas li ntawd, cov cuab yeej yuav tsum txhawb nqa ntau yam kev hloov pauv thiab siv lub tshuab ntxuav ceev kom ua tiav cov khoom noj dev, cov zaub mov miv, thiab cov khoom noj sib txawv, yog li txhim kho kev tsim khoom.

Thib peb, qhov tuag loj yuav tsum raug xaiv raws li tus tsiaj yug thiab loj. Cov dev me thiab cov khoom noj me me yuav tsum muaj 2.0-2.5mm aperture tuag rau me me, yooj yim zom pellets; cov khoom noj dev loj tuaj yeem muaj qhov loj dua ntawm 4.0-5.0mm rau cov pellets loj me me kom ua kom satiety; cov khoom noj miv tuag raug pom zoo kom siv ib puag ncig lossis pob txha- zoo li lub qhov tsim, uas tsis tsuas yog haum rau miv noj zaub mov xwb tab sis kuj txo cov khoom noj. Cov tuag yuav tsum muaj cov qauv tso tawm sai sai, nrog lub sijhawm hloov tsis pub dhau 5 feeb, ua kom yooj yim me me -batch, ntau- qhov loj me. Tib lub sijhawm, cov khoom noj tsiaj extruders 'txoj kev txias yuav tsum siv cov cua txias qis kom tsis txhob muaj cua kub ceev los ntawm qhov ua rau poob ntawm cov pellet nto. Lub sij hawm txias yuav tsum tau tswj ntawm 2-3 feeb kom ntseeg tau tias cov pellet kub poob rau hauv chav tsev kub, tiv thaiv condensation tom qab ntim.
