Los ntawm cov khoom xyaw hwm kom siab tshaj -Lub Zog Kibble - Muaj pes tsawg txoj kev zais cia nyob hauv Kab Ntsig Extrusion?

Ntau thiab ntau tus tswv tsiaj tau mob siab rau qhov zoo ntawm lawv cov tsiaj cov zaub mov tseem ceeb. Ntawm ntau hom khoom noj tsiaj, extruded kibble tau dhau los ua kev lag luam tseem ceeb ua tsaug rau nws cov palatability zoo, khoom noj khoom haus ruaj khov, thiab kev nyab xeeb siab. Tab sis koj puas tau xav paub tias cov khaub ncaws zoo li cas, cov miv thiab dev kibbles hloov los ntawm cov nplej? Niaj hnub no, peb coj koj mus rau hauv lub chaw tsim khoom noj khoom haus kev lag luam los nthuav tawm cov cuab yeej tseem ceeb thiab cov txheej txheem logic tom qab txhua kauj ruam - los ntawm cov khoom siv raw mus rau cov khoom tiav.

Lub Formulation: A Precise Science

Cov qauv khoom noj tsiaj yog tsim los ntawm kev noj zaub mov zoo. Raws li kev xav tau kev noj haus ntawm cov tsiaj, cov khoom xyaw feem ntau muab faib ua ob peb pawg:

Lub zog lub hauv paus: Pob kws, nplej, nplej, nplej xim av, thiab lwm yam cereals muab cov carbohydrates thiab tsim cov pob txha pob txha rau kev nthuav dav.

Protein qhov chaw: nqaij qaib noj, ntses noj, nqaij thiab pob txha noj mov, soybean pluas noj, thiab lwm yam., txiav txim siab cov amino acid tshuav ntawm cov khoom kawg.

Cov rog thiab roj: nqaij qaib, roj ntses, roj zaub, thiab lwm yam, muab cov fatty acids tseem ceeb thiab txhim kho palatability.

Functional additives: Vitamin premixes, minerals, prebiotics, fiber, etc., txhawb kev noj qab haus huv thiab kev zom zaub mov.

Ua ntej nkag mus rau hauv cov kab ntau lawm, cov khoom siv raw no tau txais kev tu thiab tshuaj xyuas kom tshem tawm cov impurities, xyuas kom txhua batch yog huv thiab nyab xeeb. Txawm hais tias ib kauj ruam yooj yim, nws txiav txim siab qhov kev ruaj ntseg ntawm txhua cov txheej txheem tom ntej.

Los ntawm hmoov mus rau Pellet - Txheej txheem kev sib tshuam

Cia peb ua ib qho kev sib tw twin-ntsia hlau ntub-extrusion kab ua piv txwv thiab rhuav tshem nws ib kauj ruam.

① Fine Sib Tsoo - Rauj Zeb

Cov ntaub ntawv sib txawv yuav tsum tau ua hauv av rau qhov tshwj xeeb zoo, feem ntau 60-80 mesh lossis finer. Qhov sib txawv ntau qhov zoo, qhov zoo dua qhov txias thiab extrusion tau, thiab qhov smoother ntawm pellet nto. Qhov no yog ua tiav los ntawm ib qho rauj-hom micro-grinder, uas ua kom cov hmoov zoo flowability thiab txo qis kev sib cais.

② Precise Batching & Mixing - Batching Scale & Twin-Shift Paddle Tov Khoom

Kev sib xyaw ua ke ib lub kaum los yog kaum ob ntawm cov khoom sib xyaw ua ke yog tus yuam sij kom ua kom muaj kev noj haus zoo sib xws hauv txhua qhov kib. Tom qab tsis siv neeg qhov hnyav los ntawm lub computer-tswj batching system, cov khoom xyaw nkag mus rau hauv lub tshuab twin-shaft paddle tov khoom. Cov cuab yeej siv no ua kom muaj kev sib txig sib luag hauv lub sijhawm luv luv, nrog cov residue tsawg los tiv thaiv kev sib kis.

③ Conditioning - Khawv koob ua ntej Extrusion - High-Efficiency Conditioner

Cov hmoov sib xyaw yog muab tso rau hauv qhov sib txawv-inch txias txias lossis ntxaib-ncej txias txias, qhov twg chav thiab cov dej tsim nyog tau txhaj. Cov khoom yog rhuab mus rau 80-95 degree, pib starch gelatinization thiab protein denaturation, ua kom sov, elastic "dough." Cov kauj ruam no teev cov theem zoo meej rau extrusion.

④ Cov txheej txheem tseem ceeb: Kub-Tshav Kub Tshaj Tawm - Twin-Screw Extruder

Qhov no yog lub plawv ntawm tag nrho cov kab. Cov khoom raug thawb mus rau hauv lub thoob ntawm twin-screw extruder, qhov twg nws raug mob hnyav compression, shearing, thiab kev sib txhuam, ua rau kub thiab siab nce siab (txog 120-160℃thiab 30-40 atmospheres). Raws li lub pasty loj raug yuam tawm los ntawm qhov tuag qhov, lub siab yog dheev tso tawm, thiab superheated dej vapor flashes rau hauv chav, ua rau cov khoom puff instantly rau hauv ib tug ntxeem tau, nthuav pellet. Ib tug rotating riam txiav cov pellets rau preset lengths.

Cov cuab yeej tseem ceeb: Lub ntxaib-ntsia hlau extruder nta nws tus kheej tu lub peev xwm thiab muaj zog shear-sib tov cuam tshuam, ua rau nws tshwj xeeb tshaj yog tsim rau kev tsim cov zaub mov nrog cov nqaij tshiab slurries thiab cov ntsiab lus roj siab, thaum muab kev tswj tau yooj yim dua pellet zoo thiab ntom.

⑤ Qhuav & Txias - Siv Lub Tshuab ziab khaub ncaws & phaj txias

Freshly extruded pellets muaj cov ntsiab lus noo noo, siab kub, thiab kev ntxhib los mos. Lawv sib npaug sib npaug ntawm lub tshuab ziab khaub ncaws tsis tu ncua, qhov twg ntau txheej txheej thiab cov cua kub tswj hauv cheeb tsam maj mam txo cov dej noo, teeb tsa cov qauv pellet, thiab tsim kom muaj nkig. Tom qab ntawd lawv nkag mus rau hauv lub phaj txias kom sib npaug sab hauv thiab sab nraud qhov kub thiab txias, tiv thaiv kom tsis txhob qhuav tawm sab nraud, ntub dej sab hauv.

⑥ Flavor Enhancement & Nutrient Fortification - Nruas Coater

Tom qab ziab thiab txias, cov pellets dawb nkag mus rau hauv lub nruas txheej txheej. Raws li cov pellets poob, cov kua roj xws li cov roj nqaij qaib lossis cov roj ntses yog atomized thiab txau rau ntawm lub taub hau siab, thaum tshav kub-sensitive as-ham zoo li cov vitamins thiab flavorings sib npaug ntawm plua plav. Qhov no kaw hauv savory flavors thaum tiv thaiv cov khoom xyaw cua sov-labile.

⑦ Kev Tshuaj Ntsuam & Ntim - Vibrating Screen & Tsis Siv Neeg Ntim

Thaum kawg, cov pellets tiav lawm dhau los ntawm lub vijtsam vibrating kom tshem tawm cov nplua thiab cov khoom tawg, kom ntseeg tau tias muaj kev sib haum xeeb thiab kev ncaj ncees. Cov kibbles uas tsim nyog tau raug ntsuas thiab ntim los ntawm lub tshuab ntim tsis siv neeg, nrog nitrogen flushing los yog lub tshuab nqus tsev sealing kom ntev txee lub neej thiab tiv thaiv cov roj oxidation.

Tom qab cov txheej txheem nruj zoo li no, cov khoom noj tsiaj extruded muaj qhov zoo uas cov khoom noj hauv tsev los yog cov khoom noj txias txias nrhiav nyuaj kom phim:

High digestibility: Tag nrho cov hmoov txhuv nplej siab gelatinized thiab cov protein uas muaj roj tsawg ua rau nws yooj yim dua ntawm cov tsiaj lub plab zom mov, txhim kho kev nqus cov as-ham, thiab txhawb cov quav ua kom zoo.

Kev nyab xeeb zoo tshaj plaws thiab kev nyiam huv: Cov txheej txheem kub-siab, siab-siab tshem tawm cov kab mob phem xws li Salmonella thiab E. coli, ua tau raws li cov qauv kev nyab xeeb ntawm zaub mov.

Kev noj zaub mov sib npaug hauv txhua qhov tom: Tag nrho cov khoom xyaw yog "xauv" rau hauv ib lub pellet, tiv thaiv tsiaj los ntawm kev xaiv cov khoom tshwj xeeb.

Yooj yim cia thiab pub mis: Qhuav, zoo, thiab tsis tshua muaj kev tawg, cov kibbles ua haujlwm zoo nrog cov khoom noj tsis siv neeg. Nitrogen-flushed ntim khoom txuas ntxiv lub neej txee thaum tuav lub nkig.

Cov palatability zoo heev: Cov qauv ntxeem tau yooj yim nqus cov rog thiab cov tshuaj tsw qab, ua rau kibbles yooj yim rau tom thiab txaus siab rau cov tsiaj nyiam.

Ib qho yooj yim kibble embodies ib tug sib sib zog nqus kev koom ua ke ntawm cov khoom xyaw science, khoom engineering, thiab zoo tswj systems. Cov kab khoom noj khoom haus zoo tshaj plaws tsis yog hais txog kev tsim cov khoom siv raw - nws yog hais txog kev tswj qhov kub thiab txias, siab, lub sijhawm, thiab noo noo kom rov tsim cov khoom noj khoom haus hauv daim ntawv uas cov tsiaj tuaj yeem nkag tau yooj yim dua.

Peb mob siab rau muab cov khoom noj khoom haus zoo tshaj plaws - los ntawm ib lub tshuab ua kom tiav cov kab turnkey - pab peb cov neeg muas zaub ntim kev thaj yeeb ntawm lub siab thiab khoom noj khoom haus rau hauv txhua lub hnab khoom noj tsiaj.
