Nrog rau kev nce qib thiab kev siv cov pellet pub rau tsiaj txhu thiab nqaij qaib, kev lag luam aquaculture, thiab cov lag luam tawm tshiab xws li cov chiv chiv, hops, chrysanthemum, ntoo chips, txiv laum huab xeeb, thiab paj noob hlis noj, ntau thiab ntau chav siv lub nplhaib tuag pellet mills. Vim muaj qhov sib txawv ntawm cov mis pub mis thiab qhov sib txawv hauv cheeb tsam, cov neeg siv muaj qhov sib txawv ntawm cov khoom noj pellet. Txhua lub chaw tsim khoom noj yuav tsum muaj cov pellet zoo thiab qhov ua tau zoo tshaj plaws pelleting rau cov pellet pub nws tsim. Vim muaj cov qauv pub sib txawv, kev xaiv ntawm lub nplhaib tuag tsis muaj thaum nias cov pellet pub kuj txawv. Cov tsis yog tsuas yog xav txog nyob rau hauv kev xaiv ntawm cov khoom, pore txoj kab uas hla, pore puab, nam piv, thiab qhib piv. Kev xaiv ntawm lub nplhaib tuag tsis yuav tsum tau txiav txim siab raws li cov tshuaj muaj pes tsawg leeg thiab lub cev muaj zog ntawm ntau yam khoom siv raw uas tsim cov qauv pub. Cov tshuaj muaj pes tsawg leeg ntawm raw cov ntaub ntawv feem ntau suav nrog cov protein, hmoov txhuv nplej siab, rog, cellulose, thiab lwm yam. Lub cev lub cev ntawm cov khoom siv raw feem ntau suav nrog particle loj, noo noo, muaj peev xwm, thiab lwm yam.

Cov tsiaj nyeg thiab nqaij qaib pub tsuas yog muaj cov nplej thiab pob kws, nrog cov hmoov txhuv nplej siab thiab cov ntsiab lus fiber ntau. Nws yog ib qho khoom noj uas muaj hmoov txhuv nplej siab. Txhawm rau nias cov khoom noj no, nws yuav tsum xyuas kom meej tias cov hmoov txhuv nplej siab siab gelatinized thiab ua tau raws li qhov kub thiab txias thiab kev ua haujlwm. Lub thickness ntawm lub nplhaib tuag feem ntau yog tuab, thiab lub aperture Qhov ntau yog dav, thiab qhov sib piv yog feem ntau ntawm 1: 8-1: 10. broiler qaib thiab ducks yog cov khoom noj muaj zog uas muaj roj ntau, yooj yim granulation, thiab kuj loj ib nrab ntev thiab txoj kab uas hla ntawm 1:13.

Cov khoom noj hauv dej feem ntau suav nrog cov ntses pub, cw noj, mos-shelled vaub kib pub, thiab lwm yam. Cov ntses pub muaj cov ntsiab lus siab fiber ntau, thaum cov cw noj thiab cov mos-shelled vaub kib pub muaj cov ntsiab lus tsis tshua muaj fiber ntau thiab cov protein ntau, uas yog siab. - noj protein. Cov ntaub ntawv hauv dej yuav tsum tau muaj kev ruaj ntseg ntev ntawm cov khoom hauv dej, qhov sib npaug ntawm txoj kab uas hla thiab zoo huv si, uas yuav tsum muaj qhov loj me me thiab qib siab ntawm ripening thaum cov khoom siv granulated, thiab siv cov txheej txheem ua ntej ripening thiab post-ripening. Txoj kab uas hla ntawm lub nplhaib tuag siv rau ntses pub yog feem ntau ntawm 1.5-3.5, thiab qhov sib piv feem ntau yog nyob nruab nrab ntawm 1: 10-1: 12. Lub aperture ntau ntawm lub nplhaib tuag siv rau cw noj yog nyob nruab nrab ntawm 1.5-2.5, thiab qhov ntev-rau-txoj kab uas hla yog nyob nruab nrab ntawm 1:11-1:20. Cov kev txwv tshwj xeeb ntawm qhov sib piv ntev-rau-inch yog xaiv Nws yuav tsum tau txiav txim siab raws li cov khoom noj khoom haus ntsuas hauv cov mis thiab cov kev cai ntawm cov neeg siv. Nyob rau tib lub sijhawm, tus qauv tsim ntawm qhov tuag qhov zoo tsis siv cov kauj ruam ntau li ntau tau nyob rau hauv cov xwm txheej ntawm lub zog tso cai, txhawm rau xyuas kom meej tias cov khoom txiav yog qhov ntev thiab txoj kab uas hla.

Lub compound fertilizer yog tsim los ntawm inorganic chiv, organic chiv thiab minerals. Inorganic chiv nyob rau hauv compound chiv xws li urea yog ntau corrosive rau lub nplhaib tuag, thaum cov minerals yog heev abrasive rau lub tuag qhov thiab puab lub khob hliav qab qhov ntawm lub nplhaib tuag, thiab lub extrusion quab yuam yog kuj siab. loj. Qhov txoj kab uas hla ntawm compound fertilizer nplhaib tuag yog feem ntau loj, xws li ntawm 3 mus rau 6. Vim qhov loj coj coefficient, lub qhov tuag yog nyuaj rau tso tawm, yog li qhov ntev-rau-inch ratio yog me me, feem ntau ntawm 1:4. —1:6 . Cov chiv muaj cov kab mob, thiab qhov kub yuav tsum tsis pub tshaj 50-60 degrees, txwv tsis pub nws yooj yim tua cov kab mob. Yog li ntawd, lub compound fertilizer yuav tsum tau ib tug qis granulation kub, thiab feem ntau cov phab ntsa thickness ntawm lub nplhaib tuag yog kuj nyias. Vim yog qhov hnyav hnyav thiab tsim kua muag ntawm cov chiv chiv rau ntawm lub nplhaib tuag qhov, cov kev cai ntawm lub qhov taub tsis nruj heev. Feem ntau, lub nplhaib tuag yog scrapped thaum qhov sib txawv ntawm lub siab rollers tsis tuaj yeem hloov kho. Yog li ntawd, qhov ntev ntawm lub kauj ruam yog siv los xyuas kom meej qhov sib piv thiab txhim kho qhov kev pab cuam kawg ntawm lub nplhaib tuag.

Cov ntsiab lus ntawm crude fiber nyob rau hauv hops yog siab thiab muaj ntau hom, thiab qhov kub thiab txias feem ntau tsis tuaj yeem tshaj 50 degrees, yog li cov phab ntsa thickness ntawm lub nplhaib tuag rau nias hops yog nyias, thiab qhov ntev thiab txoj kab uas hla yog luv luv, feem ntau txog 1: 5, thiab particle txoj kab uas hla yog loj ntawm 5-6 ntawm.

Chrysanthemum, txiv laum huab xeeb, pluas noj, thiab sawdust muaj ntau cov khoom siv raw, cov ntsiab lus fiber ntau yog ntau tshaj 20%, cov roj cov ntsiab lus yog tsawg, kev sib txhuam tsis kam ntawm cov khoom dhau los ntawm qhov tuag qhov loj, granulation. kev ua haujlwm tsis zoo, thiab qhov hardness ntawm granules yuav tsum tau. Tsawg, nws nyuaj rau ua tau raws li qhov yuav tsum tau ua yog tias nws tuaj yeem tsim tau feem ntau, qhov particle txoj kab uas hla yog qhov loj, feem ntau ntawm 6-8, thiab qhov sib piv feem ntau yog li 1: 4-1: 6. Vim tias cov khoom noj no muaj qhov loj me me thiab qhov loj ntawm lub qhov tuag, daim kab xev yuav tsum tau siv los kaw lub voj voog sab nrauv ntawm qhov tuag qhov chaw ua ntej granulation, kom cov khoom tuaj yeem ntim rau hauv lub qhov tuag thiab tsim. , thiab tom qab ntawd daim kab xev yog rhais tawm.

Rau cov granulation ntawm ntau yam ntaub ntawv, dogma tsis tau rigidly ua raws li. Nws yog ib qho tsim nyog los xaiv lub nplhaib tuag tsis raug thiab kev ua haujlwm raws li cov yam ntxwv granulation ntawm cov khoom thiab cov yam ntxwv tshwj xeeb ntawm txhua lub chaw tsim khoom noj. Tsuas yog los ntawm kev ua raws li cov xwm txheej hauv zos tuaj yeem tsim cov khoom noj zoo.

Ua rau kev tshuaj xyuas thiab kev txhim kho txoj kev ntawm cov khoom tsis zoo

Pub cov khoom siv feem ntau muaj cov pellets txawv txav thaum tsim khoom noj, uas cuam tshuam rau cov tsos thiab sab hauv zoo ntawm cov pellets, yog li cuam tshuam rau kev muag khoom thiab lub koob npe nrov ntawm lub Hoobkas pub. Cov hauv qab no yog cov npe ntawm cov laj thawj rau qhov txawv txav uas feem ntau tshwm sim hauv cov mills pub thiab ib daim ntawv teev cov txheej txheem txhim kho:
