Zifukwa ndi Mayankho a Kutsekeka kwa Granulator ya Chakudya (mphero ya pellet)

Pakupanga chakudya chenicheni, chifukwa cha zifukwa zosiyanasiyana, "mphika wopangidwa ndi zinthu" ukhoza kupangidwa pakati pa mphete yozungulira ndi chozungulira choponderezera, zomwe zimapangitsa mavuto monga kutsekeka, kutsekeka, ndi kutsetsereka kwa granulator.

Tapeza mfundo zotsatirazi kudzera mu kusanthula kothandiza komanso zomwe takumana nazo pa malo omwe mlanduwu udachitikira:

1, Zinthu zopangira

Zipangizo zokhala ndi starch yambiri zimakhala ndi gelatinization ya nthunzi ndipo zimakhala ndi kukhuthala kwina, komwe kumathandiza kupanga ulusi; Pazipangizo zokhala ndi ulusi wambiri, mafuta ambiri amafunika kuwonjezeredwa kuti achepetse kukangana panthawi ya granulation, zomwe zimathandiza kuti zinthuzo zidutse mu nkhungu yozungulira ndipo granular zomwe zimachokera zimakhala ndi mawonekedwe osalala.

2、Kuchotsa kosayenera kwa die roll

Mpata pakati pa ma roller a nkhungu ndi waukulu kwambiri, zomwe zimapangitsa kuti gawo la zinthu pakati pa ma roller a nkhungu likhale lokhuthala kwambiri komanso losagawidwa mofanana. Roller yokakamiza imatha kutsetsereka chifukwa cha mphamvu yosagwirizana, ndipo zinthuzo sizingachotsedwe, zomwe zimapangitsa kuti makina atseke. Kuti makina achepetse kutsekeka, chisamaliro chiyenera kuperekedwa pokonza mpata pakati pa ma roller a nkhungu panthawi yopanga, nthawi zambiri 3-5mm ndi yomwe imakondedwa.

3, Mphamvu ya khalidwe la nthunzi

Zinthu zabwino kwambiri pa ndondomeko ya granulation ndi izi: chinyezi choyenera cha zinthu zopangira, nthunzi yabwino kwambiri, komanso nthawi yokwanira yotenthetsera. Kuti tinthu tating'onoting'ono tikhale tabwino komanso kutulutsa bwino, kuwonjezera pa kugwira ntchito bwino kwa magawo osiyanasiyana otumizira a granulator, nthunzi youma yodzaza yomwe imalowa mu conditioner ya granulator iyeneranso kutsimikiziridwa.

Kutsika kwa nthunzi kumapangitsa kuti zinthuzo zikhale ndi chinyezi chambiri potuluka mu conditioner, zomwe zingayambitse kutsekeka kwa dzenje la nkhungu ndi kutsetsereka kwa pressure roller panthawi ya granulation, zomwe zimapangitsa kuti makina atseke. Izi zimaonekera makamaka mu:

① Kupanikizika kosakwanira kwa nthunzi komanso chinyezi chochuluka kungayambitse kuti zinthuzo zitenge madzi ambiri. Nthawi yomweyo, pamene kupanikizika kuli kochepa, kutentha kwa zinthuzo kumakhala kochepa, ndipo wowuma sungathe kusungunuka bwino, zomwe zimapangitsa kuti granulation ikhale yoipa;

② Kuthamanga kwa nthunzi sikukhazikika, kumasintha kuchoka pa kukwera kupita pa kutsika, ndipo khalidwe la zinthu silikhazikika, zomwe zimapangitsa kuti mphamvu ya granulator isinthe kwambiri, ludzu losafanana la zinthu, komanso kutsekeka mosavuta panthawi yopangira zinthu.

Kuti achepetse kuchuluka kwa kuyimitsidwa kwa makina chifukwa cha nthunzi yabwino, ogwira ntchito m'mafakitale odyetsera zakudya ayenera kusamala ndi chinyezi cha zinthuzo atazitenthetsa nthawi iliyonse. Njira yosavuta yodziwira ndikutenga zinthu zingapo kuchokera mu conditioner ndikuzigwira ngati mpira, ndikuzisiya kuti zingomwaza.

4. Kugwiritsa ntchito ma ring dies atsopano

Kawirikawiri, pamene chogwirira chatsopano cha mphete chikugwiritsidwa ntchito koyamba, chiyenera kuphwanyidwa ndi zinthu zamafuta, ndi kuwonjezeka koyenera kwa pafupifupi 30% ya mchenga wa emery, ndikuphwanyidwa kwa mphindi pafupifupi 20; Ngati pali zinthu zambiri mu chipinda cha granulation, ndipo mphamvu yamagetsi ikuchepa poyerekeza ndi kuphwanyidwa, imakhala yokhazikika, ndipo kusinthasintha kwake kumakhala kochepa. Pakadali pano, makinawo akhoza kuyimitsidwa ndipo momwe granulation imagwirira ntchito zitha kuwonedwa. Granulation ndi yofanana ndipo imafika pa 90%. Pakadali pano, gwiritsani ntchito zinthu zamafuta kuti mukanikize ndikuyikanso zinthu za mchenga kuti mupewe kutsekeka kwina.

5. Momwe mungachotsere kutsekeka

Ngati chikombole cha mphete chatsekedwa panthawi yopanga, mafakitale ambiri odyetsera zakudya amagwiritsa ntchito ma drill amagetsi kuti aboole zinthuzo, zomwe zingawononge kusalala kwa dzenje la chikombole ndikuwononga kukongola kwa tinthu tating'onoting'ono.

Njira yabwino yolimbikitsira ndi kuwiritsa chikombole cha mphete mu mafuta, chomwe ndi kugwiritsa ntchito poto yamafuta yachitsulo, kuyikamo mafuta otayira a injini, kuviikamo chikombole chotsekedwa, kenako kuchitenthetsa ndi kuchitentha pansi mpaka phokoso losweka, kenako nkuchitulutsa. Pambuyo poziziritsa, kukhazikitsa kumamalizidwa, ndipo granulator imayatsidwanso malinga ndi momwe ntchito ikuyendera. Zipangizo zomwe zimatseka chikombole cha mphete zimatha kutsukidwa mwachangu popanda kuwononga tinthu tating'onoting'ono.
