Iindlela zokuphucula i-Feed Pellet Durability Index (PDI)

I-Pellet Durability Index (PDI) yindlela eqhelekileyo yokulinganisa umgangatho we-pellet emzimbeni weshishini lokutya. Ilinganiswa ngokuwisa isampuli yee-pellets kwisixhobo sokuvavanya esimiselweyo (indlela ye-Holmen pneumatic okanye i-Kansas State tumbling can) kunye nokubala ipesenti yee-pellets ezihlala zinjalo, i-PDI ichaphazela ngokuthe ngqo ukusebenza kakuhle kokutya, ukusebenza kwezilwanyana, kunye nokwaneliseka kwabathengi. Ii-pellets eziqhekekayo ngexesha lokuphathwa zivelisa iifizi—amasuntswana amancinci ahlelwa zizilwanyana kwaye alahlwayo kwindawo yokutya—ukutya okuchithayo, kunyusa iindleko ngekhilogram yokwanda kobunzima obuphilayo, kwaye kuthomalalise ukufana kwesondlo okwenziwe ziingcali zesondlo. Eli nqaku lihlola izinto ezichaphazela i-PDI kwaye libonisa amaqhinga asebenzayo okuphucula.

1. Uqoqosho lwe-PDI

Umgangatho ophantsi wepellets unemiphumo elinganisekayo yezemali:

- Inkunkuma yokutya. Iintlawulo ezingamkelekanga kwindawo yokutya zimela ukulahleka kokutya ngqo. Kwimisebenzi yokutya kweenkomo, iintlawulo ezenziwe ngexesha lokuthuthwa okukhulu kwiindlela ezingagayiwanga zinokufikelela kwi-5–15% yobunzima obuhanjiswayo xa i-PDI iwela ngaphantsi kwe-90%.

- Ukusebenza kwezilwanyana okunciphileyo. Iintaka kunye nezilwanyana ezihlela ukutya zitya ukutya okungalinganiyo okwahlukileyo kwiprofayili yesondlo esicwangcisiweyo, okunciphisa izinga lokukhula kunye nokusebenza kakuhle kokuguqulwa kokutya.

- Ukugcinwa kwabathengi. Iifektri zorhwebo ezibonelela ngemisebenzi yenkukhu edibeneyo okanye abavelisi bemfuyo abazimeleyo bajongene nezohlwayo zesivumelwano kunye nokungafunwa kwabathengi xa i-PDI iwela ngaphantsi kwemimiselo yesivumelwano.

Uphononongo lwetyala laseHongyang eKazakhstan lubonise ngokucacileyo ubudlelwane: xa i-PDI ekutyeni kweenkomo iphucuke ukusuka kwi-88.7% ukuya kwi-94.2% (ukwanda kwamanqaku nge-5.5%), amandla okusebenza emihla ngemihla anyuke ukusuka kwi-130 ukuya kwi-178 yeetoni—uphuculo lwe-36.9% lokuvelisa olukwabonelela ngomgangatho ongcono weepellet [1].

2. Ubunzima beeFactor: Yintoni eqhuba iPDI?

Uphando lweshishini lufumanise ubunzima obuqikelelweyo begalelo kwizinto ezintlanu eziphambili ezichaphazela ukuqina kwepellet:

Isici: Ukwenziwa kokutya (iimpawu zokubopha izithako). Igalelo eliqikelelweyo kwi-PDI: 40%.

Isici: Ukulungisa imeko (umphunga, ukufuma, ubushushu, ixesha). Igalelo eliqikelelweyo kwi-PDI: 20%.

Isici: Ukusila (ukusasazwa kobungakanani bamasuntswana). Igalelo eliqikelelweyo kwi-PDI: 20%.

Isici: Iinkcukacha zedayi yeringi (umlinganiselo woxinzelelo, uyilo lwemingxunya). Igalelo eliqikelelweyo kwi-PDI: 15%.

Ingongoma: Ukuphola nokomisa. Igalelo eliqikelelweyo kwi-PDI: 5%.

Ezi zilinganiso ziqikelelwa kwaye zihambelana nesicelo, kodwa zibonisa ingongoma ebalulekileyo: ngaphezulu kwesinye kwisithathu se-PDI kugqitywa ziiparameters ezinokulungiswa kwi-pellet mill—ukulungisa, ukugaya, kunye neenkcukacha ze-die—okwenza i-PDI ibe yi-metric elawulekayo kwii-mills ezizimisele ukuphucula iinkqubo zazo.

3. Ukwenziwa kwesondlo: I-40% Factor

Ukwenziwa kwemveliso yeyona nto inegalelo elikhulu kwi-PDI, kodwa kudla ngokuba yeyona inzima kakhulu—iingcali zezondlo zizama ukusebenza kwezilwanyana kunye nexabiso lazo, kungekhona ukuqina kwe-pellet. Nangona kunjalo, ngaphakathi kwemida yesondlo, utshintsho oluninzi lwemveliso luphucula i-PDI:

Umxholo wesitatshi. Ukufakwa kwesitatshi kwi-gelatinization ngexesha lokulungiswa kunye nokufakwa kwe-pellet kubonelela ngendlela ephambili yokubopha. Iifomyula ezinomxholo ophezulu wesitatshi (umbona, ingqolowa, irhasi) zihlala zingcono kwi-pellet. Iifomyula ezisekelwe kumbona ezinomxholo wombona ongaphezulu kwe-60% zixhamla kwimilinganiselo ephantsi yokucinezelwa (uluhlu lwe-1:5) evumela ukufakwa kwesitatshi kwi-gelatinization ngaphandle kokuqina komphezulu [2].

Ukongezwa kwamafutha/ioyile. Amafutha asebenza njengesithambisi ngexesha lokugalela, enciphisa ukungqubana kunye noxinzelelo lokufa. Ngelixa ukufakwa kwamafutha emva kokugalela kuphucula umgangatho wepellet ngokugquma umphezulu wepellet, amafutha amaninzi kwi-pre-pelleting mash (ngaphezulu kwe-3%) anciphisa kakhulu i-PDI ngokuphazamisa ukubopha kwesitatshi kunye neproteni. Umgaqo osebenzayo: ungongeza amafutha angaphezu kwe-1–2% kwi-mixer; faka amafutha aseleyo emva kokugalela.

Imithombo yeeProtein. Izinto zokubopha zendalo ezifana ne-gluten yengqolowa kunye neenxalenye ezithile zomgubo wesoya ziphucula i-PDI ngokutshintsha kweproteni kunye nokudibanisa ngexesha lenkqubo yokugaya. Ngokwahlukileyo koko, amanqanaba aphezulu emithombo yeeprotein engabophiyo (njengomgubo we-cottonseed) anokunciphisa i-PDI.

Ifayibha. Amanqanaba efayibha aphakathi (3–8%) aphucula umgangatho we-pellet ngokubonelela nge-matrix yesakhiwo. Nangona kunjalo, amanqanaba aphezulu efayibha (ngaphezulu kwe-10–12%) anciphisa i-PDI kuba amasuntswana e-fibrous ayamelana nokucinezelwa kwaye adala iindawo ezibuthathaka kwisakhiwo se-pellet.

4. Ukulungisa imeko: I-20% Factor

Ukulungisa imeko yeyona nto ilawulekayo yokuphucula i-PDI. Injongo kukufikelela ekungeneni kobushushu kunye nokufuma okufanayo okuvuselela i-starch gelatinization kunye ne-protein plasticization ngaphambi kokuba izinto zingene kwi-die.

Iiparameters zokuLungisa eziLungileyo:

Uhlobo lokutya: Ukutya kweenkukhu (i-corn-soy). Ukufuma okujoliswe kuko: 15–17%. Ubushushu obujoliswe kuko: 80–85°C. Ixesha lokuGcina: imizuzwana engama-30–60.

Uhlobo lokutya: Ukutya okufakwe ileya. Ithagethi yokufuma: 15–16%. Ubushushu Ithagethi: 75–80°C. Ixesha lokuyigcina: imizuzwana engama-30–45.

Uhlobo lokutya: Ukutya kwehagu. Ithagethi yokufuma: 15–17%. Ubushushu Ithagethi: 75–85°C. Ixesha lokuyigcina: imizuzwana engama-45–90.

Uhlobo lokutya: Ukutya kweenkomo (ifayibha ephezulu). Ithagethi yokufuma: 14–16%. Ubushushu Ithagethi: 70–80°C. Ixesha lokuyigcina: imizuzwana engama-60–120.

Uhlobo lokutya: Ukutya okumanzi. Ithagethi yokufuma: 16–18%. Ubushushu Ithagethi: 85–95°C. Ixesha lokuyigcina: imizuzwana engama-90–180.

Ixesha elide lokugcina amanzi liphucula ukufana kwendlela yokuwagcina. Ii-conditioner ze-double-shaft okanye zexesha elide ezigcina amanzi ukuya kwimizuzwana engama-90-180 zinceda kakhulu i-PDI, ngakumbi kwi-aqua feed apho ukuzinza kwamanzi kubalulekile.

Umgangatho woMphunga. Umphunga ogcweleyo (hayi umphunga omanzi owongeza umswakama ogqithisileyo, okanye umphunga oshushu kakhulu ongadlulisi ubushushu obaneleyo) ubalulekile. Umphunga omanzi wonyusa ukungqubana kwemingxunya yokufa kwaye unokunciphisa i-PDI; umphunga oshushu kakhulu awupheki kakuhle umxube.

5. Ukusila: I-20% Factor

Ukusasazwa kobungakanani bamasuntswana kuchaphazela umgangatho we-pellet ngeendlela ezimbini: indawo yomphezulu ekhoyo yokubopha i-starch-protein kunye noxinano lokupakisha amasuntswana ngaphakathi komngxuma wokufa.

Ubungakanani obufanelekileyo beeNgcambu. Kwininzi yokutya kweenkukhu, ububanzi bejometri ephakathi kwee-microns ezingama-600–800 bubonelela ngokulinganisela okungcono kwe-PDI kunye nokusebenza kwezilwanyana. Ukusila okucolekileyo kwandisa indawo yomphezulu ekhoyo yokubopha kodwa kwandisa iindleko zamandla okusila. Ukusila okucolekileyo kunciphisa amandla okubopha.

Ukufana. Ukusasazwa kobukhulu besuntswana obuncinci kubaluleke ngakumbi kunobungakanani obuthile ekujoliswe kubo. Ukusasazwa okubanzi kuvelisa iipellets ezinoxinano lwangaphakathi oluguquguqukayo, nto leyo edala amachaphaza abuthathaka anciphisa i-PDI.

6. I-Ring Die: I-15% Factor

I-ring die ichaphazela i-PDI ngeeparameter ezintathu:

Umlinganiselo woxinzelelo. Umlinganiselo ophezulu woxinzelelo uvelisa iipellets eziqinileyo ezine-PDI engcono—ukuya kuthi ga kwinqanaba elithile. Idatha yovavanyo malunga nokutya kombona-isoya ibonisa ukuba ubunzima bepellet buyanda ukusuka kwi-85N kwi-1:5 ukuya kwi-170N kwi-1:8, kunye nokunciphisa kwezinga leentlawulo ezifanayo ukusuka kwi-12.3% ukuya kwi-4.8% [2]. Nangona kunjalo, ngaphaya kwe-1:7, ukwanda kobunzima kuncipha ngelixa umthamo wehla. Umlinganiselo ofanelekileyo woxinzelelo lwe-PDI kufuneka ulungelelaniswe neemfuno zomthamo wemveliso.

Imeko yeMingxunya Yokufa. Imingxunya yokufa egugileyo—eyandisiweyo nerhabaxa ngenxa yokuguguleka okurhabaxa—ivelisa iipellets ezine-PDI ephantsi kuba umlinganiselo woxinzelelo olusebenzayo uyancipha kwaye uxinzelelo lwe-extrusion aluhambelani. Uphando malunga nokutya kweenkuku zenyama yohlobo lwe-die (entsha kunye nelungisiweyo) luchaphazele kakhulu ukwakheka kwepellet kunye ne-crumble kwi-feed mills zorhwebo [3].

Uyilo lweDie Hole. Ukufakwa kwemingxunya efakwe kwi-countersunk kuphucula ukuhamba kwezinto kwi-die, kunciphisa ukucinezelwa kwangaphambili kwaye kukhuthaza ukwakheka kwe-pellet efanayo. Uyilo lwemingxunya ethe tye enokukhululwa okwaneleyo (ubunzulu be-countersink 2–3 mm) luqhelekile kwiisicelo ezininzi zokutya.

7. Isifundo seTyala: Uphuculo lweKazakhstan PDI

Uphononongo lwetyala lwaseHongyang Kazakhstan lubonelela ngokuqinisekiswa kwale migaqo. Lo matshini wokugaya utshintshe umatshini wokugaya ipellet osele ukhulile (ufakelo luka-2012, ubomi bokujika buncitshiswe ukuya kwiiyure ezingama-600) ngeyunithi entsha yeHongyang SZLH-series. Izigqibo eziphambili zoqwalaselo ziquka:

- Umlinganiselo woxinzelelo oluchanekileyo lwesicelo: 1:9–1:10 kwisabelo seenkomo (18–22% ifayibha eluhlaza), 1:7–1:8 kwisabelo seegusha (ifayibha ephezulu)

- I-X46Cr13-equivalent ring die ene-vacuum hardening kwi-HRC 58–60

- Iigobolondo zerola ezihambelanayo ezivela kwibanga elifanayo lentsimbi ye-alloy

- Injini esebenza kakuhle kakhulu ye-IE3

Iziphumo emva kweenyanga ezisibhozo zokusebenza:

Ipharamitha: Ukutya kweenkomo iPDI (%). Ngaphambi koKuphuculwa (2024): 88.7. Emva koKuphuculwa (2025–26): 94.2. Utshintsho: +5.5 pp.

Umthombo: [1]

8. Uluhlu lokuhlola uPhuculo lwePDI

Kwiindawo zokufuya ezijolise kwi-PDI ≥ 92% (umgangatho weshishini lokufuya okuphambili kwezorhwebo):

1. ✅ Indlela yokuvavanya: vavanya umxholo wesitatshi, ixesha lokongeza amafutha, kunye nokufakwa kwe-binder yendalo

2. ✅ Qinisekisa ukuba i-conditioner iyasebenza: jonga umgangatho womphunga (ogcweleyo, ongamanzi), ubushushu (±2°C bendawo ekujoliswe kuyo), kunye nexesha lokugcinwa kwayo

3. ✅ Qinisekisa ukugaywa: linganisa ubungakanani bezinto ezisasazwayo (ujolise kwi-600–800 μm kwinkukhu) kunye nokufana kwazo

4. ✅ Hlola imeko yedayi: linganisa ububanzi bemingxuma (tshintsha ukuba ungaphezulu kwe-15% yokwandiswa), jonga ukuba umphezulu awugugi/uyiglasi.

5. ✅ Qinisekisa umlinganiselo woxinzelelo: qinisekisa ukuba i-CR ihambelana nefomyula (dibana nomenzi wedayi ukuze ufumane ingcebiso ethile yesicelo)

6. ✅ Jonga umsantsa werola: gcina i-0.1–0.3 mm, qinisekisa umsantsa ofanayo kumjikelezo opheleleyo

7. ✅ Vavanya ukusebenza kwe-cooler: qinisekisa ukuba ubushushu bokuphuma kwe-pellet buyi-≤ ambient +5°C, ukufuma ≤ 12.5%

Isiphelo

I-PDI ayilophawu oluzinzileyo lwefomyula yokutya ethile. Nangona ifomula inegalelo eliqikelelwa kwi-40% ekuqineni kwe-pellet, i-60% eseleyo—ukulungisa imeko, ukugaya, iinkcukacha ze-die, kunye nokupholisa—imele iiparameter ezihlengahlengiswayo ezilawulwa ngabaqhubi be-feed mill. Isifundo setyala saseKazakhstan sibonisa ukuba ukulungiswa okucwangcisiweyo kwezi zinto kunokubonelela ngophuculo lwe-PDI yepesenti ezi-5+ ngelixa ngaxeshanye kunyusa umthamo we-throughput ngama-37% kwaye kuncitshiswe ukusetyenziswa kwamandla nge-15%. Kwi-mills apho i-PDI ingumhluzi wokhuphiswano, imbuyekezo kutyalo-mali oluvela ekuphuculweni kwenkqubo kunye nokukhetha i-premium ring die kukhethwa kudla ngokufunyanwa kwiinyanga zokuphunyezwa.
