Lolu cwaningo luhlola ukuthiI-AlpenFutter GmbH, umkhiqizi wokudla kwe-trout ophethwe ngumndeni e-Upper Austria, uthuthukise umugqa wawo wokugaya ama-pellets nge-I-Hongyang SZLH420 Ring Die Pellet Millekuqaleni kuka-2024. Ezinyangeni ezingaphezu kwezingu-18 zokusebenza okuqhubekayo, umshini wokugaya ulethe ikhwalithi ye-pellet eqhubekayo enezinhlawulo ezingaphansi kuka-2%, wavumela ukuphuma okuzinzile kwe-Amathani angu-5.8–6.2 ngehoraekukhiqizeni ama-trout ajwayelekile, futhi kwaba negalelo ekwandeni kwe-FCR epulazini1.05kubikwe ngabalimi bezinhlanzi ezincane ezitholakala eduze komfula. Leli cala libonisa indlela ubuchwepheshe be-precision ring die obuvela eHongyang obusekela ngayo izidingo zekhwalithi ezidingekayo zokukhiqizwa kokudla kwezinhlanzi zanamuhla.
Ingemuva: Ukufuywa Kwezinhlanzi zase-Austrian Trout
I-Austria ingumkhiqizi omkhulu we-rainbow trout (I-Oncorhynchus mykiss) e-European Union, ngokukhiqiza kwaminyaka yonke okungaphezu kwamathani angu-4,500 ngokusho kwedatha ye-FAO kanye ne-FEAP (Federation of European Aquaculture Producers). Le mboni ibonakala ngemisebenzi yomndeni emincane kuya kwephakathi esezintabeni zase-Alps zase-Upper Austria, eStyria, naseCarinthia, lapho amanzi ahlanzekile abandayo, agcwele umoya-mpilo enikeza izimo ezinhle zokulima ama-salmonid.
Ukudla kwe-trout kumelela cishe55–65% wezindleko zokusebenza ezipheleleemapulazini e-trout ase-Austria. Ngenxa yalokho, ikhwalithi yama-pellet—ikakhulukazi ukuqina komzimba, ukuqina kwamanzi, kanye nokufana kosayizi—kunquma ngqo inzuzo yepulazi. Ukudla okunezinhlawulo eziningi akugcini nje ngokuchitha izinto zokusetshenziswa kodwa futhi kuyawohloka ikhwalithi yamanzi, kwandisa isidingo se-oxygen, futhi kuphakamisa ingozi yokucasuka kwama-gill ezinhlelweni zemigwaqo yomjaho egcwele kakhulu.
I-AlpenFutter GmbH, eyasungulwa ngo-1998, isebenzela cisheAmapulazi angu-40 e-troutkulo lonke elase-Upper Austria naseSalzburg. Le nkampani ikhiqiza amathani ayi-12,000–14,000 okuphakelwa kwamanzi okukhishwe kanye nokufakwe ama-pellet minyaka yonke, kanti ukudla okucwiliswayo okufakwe ama-pellet kubalwa cishe u-40% womkhiqizo. Umugqa wabo wokuphehla ama-pellet wawusekelwe kakhulu emshinini ojwayelekile we-pellet osebenza kahle, owawusebenze kahle iminyaka engamashumi amabili kodwa waqala ukubonisa izimpawu zomkhiqizo ongaguquki kanye nezindleko zokulungisa ezikhulayo njengoba ibhizinisi likhula.
Inselele: Ukuvumelana Kwekhwalithi Esikalini
Ngasekupheleni kuka-2023, ithimba lokukhiqiza le-AlpenFutter lathola izinkinga ezintathu ezixhumene:
I-flat-die mill ekhona ikhiqize ama-pellet anenani le-PDI (Pellet Durability Index) elishintshashintshayo phakathi88% kanye no-94%kuzo zonke izinhlobo, ngisho nalapho kucutshungulwa amafomula afanayo. Lokhu kuguquguquka kwaphoqa amapulazi angaphansi komfula ukuthi alungise amazinga okuphakela inqwaba ngenqwaba, okwenza kube nzima ukulandelela kwawo i-FCR kanye nokuphathwa kokudla.
Njengoba isidingo esivela emapulazini ezinhlanzi ezincane sanda—ngokwengxenye ngenxa yokwanda kokuthanda kwabathengi base-Austria izinhlanzi ezifuywayo endaweni—umugqa wokukhipha ama-pellet waba yisithiyo sokukhiqiza. Isilinganiso semishini yokugaya ekhona sasingu-1.5%.4.2 t/hkuma-pellets ajwayelekile okutshala i-trout angu-4 mm, angaphansi kuka-5.5 t/h adingekayo ukuze kuhlangatshezwane nama-oda esizini ephezulu ngaphandle kokusebenzisa amashifu ande.
Ukucushwa kwe-flat-die kwakudinga ukushintshwa kwe-roller shell njaloAmathani angu-400–500kokukhishwa kwemikhiqizo ye-trout enamafutha amaningi (22–25% amafutha aluhlaza). Lokhu kuhunyushwe kwaba yisikhathi sokungasebenzi esingahleliwe cishe njalo ezinsukwini zokukhiqiza eziyi-10-12, okunciphisa ukusebenza kahle kwemishini iyonke (OEE).
"Besingalahlekelwa amakhasimende, kodwa besilahlekelwa ukuzethemba ekhonweni lethu lokukala ngaphandle kokubeka engcupheni ikhwalithi. Abalimi be-trout e-Austria bayaxoxa—ukungaguquguquki kuyidumela lethu."

Ukukhetha Isixazululo: Kungani i-SZLH420 Ring Die Pellet Mill isetshenziswa
I-AlpenFutter ihlole izinketho zokugaya ama-pellet ezivela kubakhiqizi abathathu, okuhlanganisa nabaphakeli baseYurophu nabaseShayina. Izindlela zokuhlola zalinganiswa kanje:
Isilinganiso Sokuhlola
II-Hongyang SZLH420 Ring Die Pellet Millyakhethwa ngemuva kokubuyekezwa kobuchwepheshe kanye nokuhlolwa kwezinkomba namakhasimende aseHongyang akhona emkhakheni wezokufuya izinhlanzi. Izici ezibalulekile zokuthatha izinqumo zazihlanganisa:
I-SZLH420 ine-ring die enokwakhiwa kwensimbi ye-alloy eqinile nge-vacuum. I-geometry ye-die hole—ikakhulukazi isilinganiso sokucindezela kanye nomklamo wokukhulula—yenzelwe ukwakheka kwe-aquafeed okunamafutha amaningi, okunamaprotheni amaningi. Ngokungafani nemiklamo ye-flat-die lapho ukucindezela kusetshenziswa khona esigabeni esisodwa, ukucushwa kwe-ring die kusabalalisa amandla okucindezela ngokulinganayo kulo lonke umjikelezo we-die, okuholela ekuminyaneni kwe-pellet okufanayo.
I-Hongyang inikeze isethi efanayo yamagobolondo e-ring die nama-roller, akhiqizwe ngendlela ethile yokubekezelela ukukhishwa kwe-0.10–0.15 mmLokhu kufaneleka okunembile kubalulekile ekusetshenzisweni kokudla emanzini ngoba ukususwa ngokweqile kuvumela izinto ukuthi zidlule ukucindezelwa, kudale izinhlawulo; ukususwa okunganele kusheshisa ukuguguleka futhi kwandisa ukusetshenziswa kwamandla. Indlela ehambisanayo iqeda ukuguquguquka okulethwa lapho ama-rollers nama-dies etholakala ngokwehlukana.
I-SZLH420 ilinganiswe ngama-t/h angu-6–8 ekudleni kwezinkukhu okujwayelekile kanye nama-t/h angu-5–7 kuma-aquafeed anamafutha amaningi. Lokhu kunikeze indawo ekhululekile ngaphezu kwesidingo sika-AlpenFutter sama-t/h angu-5.5, okuvumela umshini wokugaya ukudla ukuthi usebenze cishe85% womthamo olinganisiwe—indawo yokusebenza evame ukwandisa isikhathi senkonzo yegobolondo le-roller.
UHongyang uzibophezele ekuqaliseni umsebenzi endaweni nonjiniyela oqeqeshwe efektri owahlala esakhiweni sase-AlpenFutter isikhathi eside.izinsuku ezinhlanu ngemuva kokufakwa, ukuqeqesha opharetha ngezinqubo zokuhlola i-ring die, izinqubo zokulungisa igebe lama-roller, kanye nokuhlela ukulungiswa kokuvimbela.
Ukufakwa Nokugunyazwa
I-SZLH420 yafakwa ngoFebhuwari 2024 ngesikhathi sewindi lokulungisa elihleliwe lesonto elilodwa. Ukuhlanganiswa ne-pre-conditioner ekhona (i-double-shaft differential conditioner) kanye ne-post-pelleting cooler kwakudinga i-transition chute entsha kanye nokuguqulwa okuncane kukagesi, okwenziwa yithimba lokulungisa langaphakathi le-AlpenFutter ngesiqondiso esikude esivela konjiniyela baseHongyang.
Ukuqaliswa kwaqhubeka ngezigaba ezintathu:
Ukuqinisekisa ukuzungeza kwenjini, ukusetha igebe le-roller-die, kanye nokusebenza kokuxhumana kokuphepha.
Kucutshungulwe amathani ayi-12 okuphakelwa kwe-trout okungu-4 mm (amaprotheni angu-42%, amafutha angu-23%) kuzo zonke izinhlobo ezine zokuhlola, kwanda kancane kancane umthamo kusuka ku-3.0 t/h kuya ku-6.0 t/h okuhlosiwe. Amasampula e-pellet aqoqwe ekukhulisweni komthamo ngamunye ukuze kuhlaziywe i-PDI yelabhorethri kanye nokuhlolwa kokuzinza kwamanzi.
Ukukhiqiza okuphelele kwamathani angu-28, nokuqapha okuqhubekayo komthwalo wemoto (kuzinzile ku-78–82%enesilinganiso esingu-160 kW), izinga lokushisa lokushisa (eligcinwe ku-72–76°C), kanye nekhwalithi yokukhipha i-pellet.
Ekupheleni kwesonto lokuqalisa ukusebenza, umshini wokugaya wawusukhululiwe ukuze ukhiqizwe ngendlela evamile.
Imiphumela: Idatha Yokusebenza Yezinyanga Eziyi-18
Idatha elandelayo ihlanganisa isikhathiKusukela ngoMashi 2024 kuya ku-Agasti 2025(izinyanga ezingu-18), okumele cisheAmathani angu-9,800ukudla kwe-trout okucutshungulwe nge-SZLH420.
5.1 Ikhwalithi ye-Pellet
| I-Metric | Ngaphambi (Ukufa Okuphansi) | Ngemva (SZLH420) | Ushintsho |
|---|---|---|---|
| I-PDI — 4 mm umlimi we-trout | 88–94% (okuguquguqukayo) | Isilinganiso esingu-96.2% (SD=0.8%) | Inzuzo yokungaguquguquki |
| Izinhlawulo (%) | >4.2% isilinganiso. | Isilinganiso esingu-1.6% | -62% |
| Ukuqina kwamanzi (imizuzu engama-30) | 82–88% | Isilinganiso esingu-93.4% | +8 amaphesenti amaphuzu |
| Ukwehlukahlukana kobuningi (iqembu ngalinye) | ±4.5% | ±1.2% | Okubalulekile |
Ukwehla kokwehluka kwe-PDI kusuka ebangeni lamaphuzu angu-6% kuya ekuphambukeni okujwayelekile okungu-0.8% kwaba ukuthuthuka okukodwa okunomthelela omkhulu ngokombono wabalimi be-trout. Ngokuhlala isikhathi eside kwe-pellet, abalimi bangakwazi ukwenza amatafula abo okuphakelayo abe sezingeni elifanayo kunokulungisa nsuku zonke ngokusekelwe ekuhlolweni kwekhwalithi ye-pellet ebonakalayo.
5.2 Ukusebenza Kahle Kokukhiqiza
| I-Metric | Ngaphambi | Ngemva | Ushintsho |
|---|---|---|---|
| Umthamo ojwayelekile (4 mm) | 4.2 t/h | 6.0 t/h | +43% |
| Ukusetshenziswa kwamandla okuqondile | 22.8 kWh/t | 19.5 kWh/t | -14.5% |
| Isikhathi sokuphila kwegobolondo le-roller (amathani ngesethi ngayinye) | 400–500 t | 1,100–1,300 t | +160% |
| Isikhathi sokuphumula esingahleliwe (amahora/inyanga) | Amahora angu-8.5 | Amahora angu-2.1 | -75% |
Ukwandiswa okukhulu kokuphila kwenkonzo yamagobolondo e-roller shell—kusukela cishe kumathani angu-450 kuya kumathani angu-1,200 ngesethi ngayinye—kwabangelwa ukususwa kwe-roller-die okuhambisanayo kanye nokwelashwa kokuqina okunembile okusetshenziswa kumagobolondo e-roller e-Hongyang. Ngesilinganiso sokukhiqiza esimaphakathi samathani angu-540 ngenyanga, izikhawu zokushintsha amagobolondo e-roller shell zanda kusukela cishe kanye ngenyanga kuya kanye njalo ezinyangeni ezingu-2.2, kunciphisa izindleko zezingxenye kanye namahora okusebenza.
5.3 Isilinganiso Sokuguqulwa Kokudla Kwasepulazini
I-AlpenFutter yenze ucwaningo lwe-FCR ngokuzithandela phakathi kwamakhasimende ayo angu-18 epulazini lama-trout cishe ezinyangeni ezingu-12 ngemuva kokuthuthukiswa kwemishini. Amapulazi ayishumi nanhlanu anikeze idatha ewusizo yesizini yokukhula ka-2024:
Nakuba i-FCR ithonywa yizici eziningi—izinga lokushisa lamanzi, ubuningi besitokisi, umoya-mpilo oncibilikisiwe, kanye nemikhuba yokuphatha ipulazi—ikhwalithi eqhubekayo yama-pellet kanye nezinhlawulo ezincishisiwe kucashunwe ngabalimi abahloliwe njengezinto ezibangela lokho.
"Ngaphambi koshintsho, besilokhu sinesendlalelo sothuli phansi kwebhokisi lethu lokugcina ukudla. Manje ama-pellets afika ephelele, futhi sondla lokho esikukalayo. Lokho kukodwa kwasinika iphuzu eliyingxenye ku-FCR."
