Pfupiso yeVatungamiriri
Mumusika wenyama dzehuku dzinokwikwidzana uko chikafu chemhuka chinotora mari inosvika70% yemari yose yekugadzira, mhando yepellet haisi yehunyanzvi - ipfungwa yekuchinja-chinja. Apo kambani yekutengesa nyama yemombe muMashonaland East Province, Zimbabwe, yakawana kuti muchina wayo wekugadzira nyama yemombe wakakura kwemakore gumi uchiburitsa mapellets akapwanyika, ane guruva aikanganisa mashandiro eboka uye achikwidza mabhiri emagetsi, vatungamiriri vepurazi vakaita danho guru: kutsiva michina yekare nemuchina wekugadzira nyama yemombe wemazuva ano wepellet kubva kuLiyang Hongyang Feed Machinery Co., Ltd.Mhedzisiro yacho yaiveKuvandudzika kwemapoinzi gumi nemaviri muzanamuPellet Durability Index (PDI), kudzikiswa kunoyerwa muFeed Conversion Ratio (FCR), uyeKuderera kwe13% mukushandiswa kwesimbapatani yezvokudya zvinogadzirwa. Chidzidzo ichi chinoongorora hunyanzvi uye hupfumi hwezvinhu zvinogadzirwa.
Nzvimbo yekudya kweNhunzi dzeBhuru muZimbabwe
Sekisheni yehuku muZimbabwe yakagadzira matani anofungidzirwa kuva zviuru makumi matanhatu nezvishanu enyama yehuku muna 2022, zvichienderana nedata reUSDA Foreign Agricultural Service, kugadzirwa kwehuku dzemombe ndiko kwakanyanya kuwanda. Chikafu chehuku chinomiririra anopfuura 70% yehuwandu hwekudya kwemumaindasitiri munyika. Sangano reZimbabwe Poultry Association rakanyora shanduko kubva pakugadzirwa kwemumagadheni kuenda kumabasa ekutengeserana akaomarara. Kuchinja uku kunowedzera njodzi yemhando yekudya: mumasisitimu ekudya ega ega ari kuwanikwa mudzimba dzehuku dzeZimbabwe, mapellets anofanira kugara achitakura michina asingaparare. Zvidimbu - zvidimbu zveguruva zvinokonzerwa nekuputsika kwemapellets - zvinoita kuti shiri dzibate zvidimbu zvakakura, zvichikonzera kuparadzaniswa kwezvinovaka muviri, kurasikirwa kwechikafu zvakanyanya, uye kufema kunorwadza kubva muguruva rinobuda mumhepo.
Papurazi reMashonaland East, dambudziko racho rakatanga. Muchina wayo wekugadzira shiri dzemhando yeflat die pellet, wakatanga kutengwa kuti ushandiswe kugadzira shiri diki, wainetseka kuendesa shiri dzemhando yepellet dzakakodzera shiri dzepurazi dzaikwanisa kukwira 80,000. Kuongororwa kwePDI kwakaitwa pamwe chete nerabhoritari yekudya yedunhu kwakaratidza avhareji ye82% - pasi pe90% threshold yaionekwa seyakaderera pakushanda kwehuku dzekutengesa. Mari dzefaindi dzaipfuura 12% mumabhegi ekudya akapedzwa.
"Kurasika kwechikafu kwaionekwa zuva nezuva," maneja wekugadzira wepurazi akafunga kudaro gare gare. "Waigona kubvisa faindi padzimba dzese. Ndiko kurasirwa kwechikafu kwawakatobhadhara, kuchizorasika."
Nyaya yeUnyanzvi yeRing Die Technology
Muganho mukuru wezvigayo zvema "flat die pellet mills" uri mukugadzirwa kwazvo kwe "mechanical architecture". Mu "flat die system", ma "rollers" anotenderera pa "die plate" yakatwasuka; nzvimbo yekudzvanya inogumira kunzvimbo ye "roller-die contact zone", uye kugoverwa kwezvinhu hakuna kuenzana. Sezvo "die" ichikura - isingadzivisike ne "abrasive Zimbabwean miganho" - "pellet" inoderera nekukurumidza.
Zvigayo zveRing die pellet zvinogadzirisa zvipingamupinyi izvi kuburikidza nedhizaini yakasiyana zvachose. MuLiyang Hongyang's SZLH series, die ring inotenderera yakatenderedza maroller asingachinji kana anotenderera pa vertical axis. Zvinhu zvinoiswa panzvimbo ye nip pakati pe roller ne die uye zvinomanikidzwa kubuda ne radially kuburikidza nemaburi e die pasi pekumanikidzwa kwakafanana. Nzvimbo yekudzvanya inoshanda yakakura zvakanyanya pa kutenderera, uye simba re centrifugal rinobatsira kugoverwa kwezvinhu, zvichiita kuti pellet igare yakafanana pamusoro pe die yese.

Tsvagiridzo yakaburitswa muKuvandudzwa kweTekinoroji yeZvekudya(2023) uye ASABE Standard S269.4 protocols dzekuongorora dzinoratidza kuti ring die configurations dzinowanzoita zvakanaka kupfuura flat die systems ne10–15% mukushanda nesimba uye 8–15 muzana yePDI yekushandiswa kwekudya kwehuku.
Iyo Liyang Hongyang Nzira
Chinosiyanisa mashandiro aLiyang Hongyang inzira yekambani yekugadzira zvinhu. Zvigayo zveSZLH ring die pellet zvinogadzirwa neCNC-machined alloy steel die rings uye case-hardened roller assemblies, zvinogadziriswa kusvika pakukwana kwakakodzera izvo zvinoderedza kudedera uye kuwedzera nguva dzebasa. Iyo integrated stainless steel conditioner inoita kuti ipinde nemhepo yakaenzana uye gelatinization - danho rakakosha rekudya kwenyama yemombe inobva kustarch uko kubika kwakakodzera kunokanganisa zvakananga kubatana kwepellet uye kuwanikwa kwezvinovaka muviri.
Vasati vatumira chigayo cheSZLH508 pellet kuZimbabwe, timu yehunyanzvi yeHongyang yakaita ongororo iri kure yehurongwa hwemitsetse yekudya yepurazi, magadzirirwo emagetsi, uye chimiro chezvinhu zvakabikwa. Izvi zvakabvumira kugadzirwa kwenzvimbo dzemakomba ekufa (dhayamita ye4.0mm, chiyero chekumanikidzwa kwemafuta echibage-soybean broiler formula) uye magadzirirwo emota akaenzana negridi ye50Hz yeZimbabwe. Kuiswa kwacho kwakapedzwa mukati memazuva mashanu. Mainjiniya weHongyang akaramba ari panzvimbo iyi kuti atange basa uye adzidziswe nevashandi, achitarisa kuongororwa kwemafuta, kugadzirisa gap re roller, uye kugadzirisa tembiricha - ruzivo rwekushandisa rwakanga rusina kugashirwa nechikwata chekuchengetedza purazi nekutenga michina kare.
Migumisiro Inoyerwa
Mwedzi mitanhatu mushure mekuvhurwa kwepurazi, purazi rakaita ongororo yakazara yekushanda kwepurazi. Zvakabuda zvakanyorwa uye zvakasimbiswa zvakazvimirira:
Hunhu hwePellet
PDI yakawedzera kubva pa82% kusvika pa94%, zvichiyerwa nenzira yeASABE tumbling can. Mari yekudya yakachengetwa mumabhegi yakaderera pasi pe5%. Mapellets akasimba akabvisa dambudziko reguruva mumitsetse yekudyisa otomatiki, uye maitiro eshiri akachinja kubva pakunhonga kwekusarudza kuenda pakushandiswa zvakaenzana.
Chiyero cheKuchinja kweChikafu
Purazi iri rakawana kuwedzera kweFCR kweinenge 6.5%, kubva pa1.68 kusvika pa1.57 panguva yekukura kwemhuka. Izvi zvinoenderana netsvagurudzo yakaburitswa kubva kuFeed International inoratidza kuti mapellets ane PDI yakawanda (>93%) anoburitsa kuwedzera kweFCR kwe3–10% zvichienzaniswa nemapellets asina kunaka mukugadzirwa kwehuku dzenyama. Kune vanogadzira matani zviuru zvina echikafu pagore, kuwedzera uku kunomiririra matani angangoita mazana maviri nemakumi matanhatu echikafu chinochengetwa pagore - mhedzisiro yakananga.
Mari yeSimba
Kushandiswa kwemagetsi kwakadzikira kubva pa22 kWh kusvika pa19.1 kWh patani, kudzikira kwe13%. Nemitengo yemagetsi muZimbabwe iri paavhareji yeUS$0.10–0.12 pa kWh kune vashandisi vemabhizinesi, izvi zvinoreva kuchengetedza mari pagore.
Nguva Yekushanda
Chigayo chekare chakati sandara chaida kumira kwekugadzirisa kusina kurongwa mavhiki ese maviri kusvika matatu nekuda kwekutadza kushanda zvakanaka kwemabheyaringi uye kusakara kweplate isina kurongeka. SZLH508, ichishanda pasi pechirongwa chimwe chete chekugadzira uye mamiriro ezvinhu ezvigadzirwa, yapedza mwedzi mitanhatu yekugadzira nguva dzose nekumira kwekuchengetedza kwekudzivirira kwakarongwa chete. Zvikamu zvekuchengetedza, izvo purazi raimbowana kuburikidza nenzira dzisina kurongeka dzekupinza zvinhu nemutengo wakakwira uye nguva refu dzekutungamira, ikozvino zvava kuwanikwa kuburikidza ne network yaLiyang Hongyang yekugovera mushure mekutengesa.
Zvinokonzera Hurongwa hweVashandi veAfrica Vanogocha Zvokudya
Nyaya yeZimbabwe inoratidza mafambiro akakura mukugaya chikafu muAfrica. USDA neFAO vese vakataura kuti mashandiro ekudya kwezvirimwa zvepakati nepakati muAfrica ari kuchinja kubva pakushandisa michina yekutanga kuenda kumichina yepamusoro sezvo ichikwidza kugadzirwa uye inotarisana nemitengo inokwira. Kuvandudza chigayo chepellet - chinonyanya kukosha pakugadzira chikafu - kunowanzopa purofiti yakawanda kubva pakudya pakati pezvimwe zvingangowanikwa.
Kuna Liyang Hongyang, kuiswa kweZimbabwe kwakasimbisa kuzvipira kwekambani kutsigira vatengi kupfuura kutengeswa kwekutanga. Pakazokumbira purazi rimwe chete remhando itsva yekudya, timu yehunyanzvi yeHongyang yakapindura nekukurudzira kwehuwandu hwekumanikidzwa mukati memaawa makumi mana nemasere, uye dhiziri rekutsiva rakaendeswa kuHarare mukati memavhiki matatu.
Iyi haisi nyaya yekutsiva michina chete. Ipfungwa yezvinozoitika kana mugadziri wezvikafu akabatana nemutengesi anoona mashandiro emuchina sehukama hweinjiniya huri kuramba huripo kwete sekutengeserana kamwe chete. Mumusika umo chikamu chimwe nechimwe chekuvandudzwa kweFCR chinoshandurwa kuita zviuru zvemadhora zvakachengetwa, musiyano iwoyo unokosha.
Mota yeSZLH508 yave ichishanda kwemaawa anopfuura 2,000 ekugadzira pachivako cheZimbabwe. Hunhu hwepellet hunoramba hwakafanana, kushandiswa kwesimba kwakaramba kuripo, uye purazi rave kutanga kuronga mutsetse wechipiri wekugadzira - nemidziyo yeLiyang Hongyang yakatsanangurwa kubva pakutanga.
