Mutsetse uyu unoshanda ne8.5 tonnes paawa, zvichienderana nechinangwa chekugadzira chakaiswa panguva yekuiswa. 1. Indasitiri yeSalmon Feed yeNorway: Zviyero uye Zvinodiwa zveTechnical Kutonga kweNorway muAtlantic salmon aquaculture kwakanyorwa zvakanaka. Muna 2024, nyika iyi yaishanda munzvimbo dzinosvika 994 dzekugadzira mvura yegungwa uye yaive nemarezenisi ekurima gungwa anosvika 2,905, ayo 1,651 aishandiswa pakugadzira salmon netrout. Huwandu hwese hwekugadzira salmon hwakasvika mamiriyoni 1.553, huwandu hwacho hwakakura nguva dzose mumakore gumi apfuura uye hunotsigira indasitiri yekutumira kunze kwenyika inodarika mabhiriyoni 150 (Eurofish, 2025). Huwandu hwekugadzira uhwu hunoda huwandu hwakawanda hwekudya. Musika wekudya kwesalmon wekuNorway unoshumirwa zvikuru nevagadziri vakuru vana - Skretting (Nutreco), Mowi Feed, Cargill (EWOS), uye BioMar - avo vakabatanidzwa vanodarika mamiriyoni 1.5 matani pagore. Mowi Feed yega yakagadzira matani 584,586 ekudya muna 2024, zvichigadzira EBITDA inoshanda ye€62.2 miriyoni, uye yakazivisa kuwedzera kwematani 60,000 pafekitori yayo yeBjugn yakarongerwa kupera panosvika Q2 2026 (Mowi Q4 2024 Report). Skretting Norway yakashuma kuti huwandu hwekabhoni yekudya kwayo hwakaderera kusvika pa1.41 kg CO2 yakaenzana pakirogiramu yechikafu muna 2024, kudzikira kwe46% kubva pakutanga kwa2020, zvichikonzerwa nekutsiviwa kwezvinhu zvakabikwa uye kuvandudzwa kwesimba (Skretting Norway Impact Report, 2024). Mafekitori ekudya akazvimiririra akadai seFjordfôr ane chikamu chakakosha asi chakakosha mumusika. Mafekitori aya anowanzo shandira mapoka ekurima emunharaunda, anopa kuchinjika kwekugadzira uko makwikwi makuru asingakwanise kuenderana nevatengi vadiki, uye anoita basa rakakosha mukuchengetedza kugona kwekutengesa mumahombekombe eNorway ane makiromita 2,500. Zvisinei, anotarisana nezvinodiwa zvehunyanzvi zvakafanana nemakambani makuru - uye mune dzimwe nzira matambudziko makuru, zvichipiwa kuti anoshanda mitsetse mishoma yekugadzira uye haakwanise kubhadhara nguva yakareba yekuzorora. Kugadzirwa kwechikafu chesalmon ndeimwe yezvikamu zvinonyanya kudiwa zvehunyanzvi muindasitiri yepasi rose yeaquafeed. Kudya kwakajairika kwevarimi veAtlantic salmon mumvura yegungwa kune 28–38% lipid, 36–42% crude protein, uye pasi pe10% nitrogen-free extract (NFE). Mafuta akawanda anowanikwa kuburikidza nekusanganiswa kwemafuta anoiswa mu-extruder (kazhinji anogumira pa12% nekuda kwezvinodiwa zvekukweshana mu-single-screw extrusion) uye post-extrusion vacuum coating iyo inosvitsa huwandu hwemafuta muzvipfuyo. Mapellets anofanira kunyura nekukurumidza kusvika pakadzika kunodiwa mumapeni emumbure, arambe aripo panguva yekudyisa mumvura kwemaminitsi 20-40, uye arambe kuora kwemuchina panguva yekufambisa, kuchengetwa, uye kutakurwa nemhepo (ScienceDirect, 2025; Nofima, 2015). Zvinhu zvemhando yepellet zvinoonekwa sezvisingabvumirwe nevarimi veNorway salmon zvinosanganisira: kugadzikana kwemvura kweinenge 88-90% mushure memaminitsi makumi matatu ekunyudzwa mumvura; Pellet Durability Index (PDI) pamusoro pe95%; kumhanya kwekunyura kunoenderana nezvinodiwa zvesystem yekudyisa; uye huwandu hwefines huri pasi pe2% panguva yekuendesa. Tsvagiridzo yakaburitswa neNofima yakaratidza kuti kugara kwenguva refu kwepellet uye kugadzikana kwemvura zvine hukama hwakanaka nekudya kwesalmon yeAtlantic, nepo kuwanda kwefines kunotungamira mukurasikirwa zvakananga kwehupfumi uye kukanganisa kwezvakatipoteredza. 2. Dambudziko paFjordfôr: Midziyo Yekare, Hunhu Huri Kuderera Pakutanga kwa2025, timu yekugadzira yaFjordfôr yakanga yanyora kudzikira kuri kuramba kuchiitika kwehunhu hwepellet kubva pamuchina wayo we ring die pellet, uyo wakanga waunganidza maawa anopfuura 36,000 ekushanda kubva pawakaiswa muna 2011. Kudzikira uku kwakaratidzwa nenzira nhatu dzinoyerwa: Chekutanga, kugadzikana kwemvura mushure memaminitsi makumi matatu kwakadzikira kubva paavhareji yenhoroondo ye88% kusvika 84%, zvichidzika pasi pezvinodiwa zvishoma zvakatsanangurwa muzvibvumirano zvekambani zvekubvisa nevatengi vekurima. Chechipiri, PDI yakanga yadzikira kubva pa94% kusvika pa91%, zvichikonzera faindi dzaiunganidzwa panguva yekufambisa uye dzakagadzira matambudziko ekubata guruva panzvimbo dzekupa purazi. Chechitatu, kushandiswa kwesimba kwakanangana kwakanga kwakwira kusvika pa14.6 kWh patani, inenge 16% pamusoro pechipimo chemazuva ano che ring die pellet mills mukirasi ye132–160 kW. Kuongorora kwechikonzero chemidzi kwakaratidza kuti ring die bore wear ndiyo chinhu chikuru. Mushure memaawa 36,000, maburi edie akaratidza kukura kwedhayamita uye kudzikira kweganda repamusoro, zvichikonzera kudzvanywa kusina kuenzana pachiso chedie. Chidziyo che single-shaft chiripo chakaratidzawo kuchinja-chinja kwetembiricha ye ±5°C panguva yekugadzira, zvichikonzera kusagadzikana kwe starch gelatinization uye kusasimba kwe pellet binding. Vatungamiriri veFjordfôr vakaongorora sarudzo nhatu: kugadzirisa mutsetse uripo ne die yekutsiva ring uye conditioner yakagadziridzwa; kutenga chigayo chitsva che pellet kubva kune mumwe wevagadziri veEurope vakakurumbira; kana kuongorora dzimwe nzira dzemitengo inokwikwidzana kubva kune vatengesi vekuAsia vane ruzivo rwakaratidza rwekudya kwe salmon. Sarudzo yekubatana neHongyang yakakurudzirwa nekutarisa kwakadzama kwereferensi nemugadziri we salmon wekuChile akange atumira Hongyang SZLH mutsetse muna 2024 uye akataura kuti kugadzikana kwemvura kuri nani kubva pa84% kusvika pa92% pamwe chete ne12% yekuchengetedza simba (Hongyang Chile Salmon Feed Case Study, 2025). 3. Mhinduro yeUnyanzvi yeHongyang: Yakagadziriswa Zvikafu zveSalmon Chikwata cheinjiniya cheHongyang chakaongorora kwemazuva mana panzvimbo iyi paFjordfôr's facility iri pedyo neNamsos, vachiongorora mashandiro aripo, vachiongorora mwedzi mitanhatu yezvinyorwa zvekugadzira, uye vachiyedza mash samples kubva mufomu yekambani yekudyara salmon. Chikumbiro chakabuda chaive pamusoro peSZLH508 ring die pellet mill yakagadzirirwa kugadzirwa kwechikafu chesalmon chine lipid yakawanda. Tsanangudzo huru dzehunyanzvi uye zvikonzero zvekugadzira zvakatsanangurwa pazasi. Ring Die Compression Ratio. Mafomu echikafu cheSalmon ane 32–36% protein uye 12–15% pre-extrusion fat content anoda huwandu hwakanyanya hwekumanikidzwa kupfuura chikafu chezvipfuyo kuti awane huwandu hwakakwana hwepellet uye kugadzikana kwemvura. Hongyang akataura chiyero chekumanikidzwa kwe1:11 che ring die, chakaverengerwa zvichibva pakugadzirwa kwaFjordfôr — inenge 28% yehove yekudya, 16% soybean protein concentrate, 14% wheat gluten, 10% yemafuta ehove (pre-extrusion), uye 8% pea starch se binder, nechiyero chinosanganisira mavhitamini nemaminerari premixes. Chiyero ichi chekumanikidzwa chinovimbisa kumanikidzwa kwakakwana kwemechanical kuti starch iite gelatinization pasina kudzvanya zvakanyanya pellet, izvo zvaizoderedza kumhanya kwekunyura uye kukanganisa maitiro ekudyisa. Dual-Shaft Differential Conditioning. Mutsetse weSZLH508 waive ne double-shaft conditioner inopa kudzora kumhanya kwakazvimirira pashaft yega yega, zvichiita kuti kugadziriswa kwakanyatsojeka kwenguva yekuchengetedza (kazhinji masekondi 60-120 ekudyisa mumvura) uye kusanganisa simba. Dhizaini iyi yakapa kupinda kwakasimba kwehunyoro uye kugoverwa kwetembiricha mukati mehuwandu hwese hwemash usati wapinda mu die. Munguva yemiedzo yekugadzira, kugadzikana kwekushisa kwe conditioner kwakachengetedzwa mukati me ±2°C panzvimbo yakatarwa ye 88°C, zvichienzaniswa ne ±5°C pamidziyo yekare. Kugadzirisa zvinhu zvakafanana kwakakosha pakudya kwesalmon nekuti gelatinization isina kukwana yestarch inoderedza kubatana kwepellet, zvichideredza kugadzikana kwemvura uye kuwedzera kugadzirwa kwemari. Ring Die Metallurgy uye Surface Finish. Hongyang yakapa vacuum-hardened alloy steel ring die (HRC 58–60) ine roughness yepamusoro pemakomba yakaposhwa kusvika Ra ≤ 0.8 μm. Iyi metallurgical specification inopa simba rekudzivirira kupfeka zvakanyanya pakurwisa hunhu hweabrasive hwe high-ash fishmeal formulations. Nzvimbo yegomba yakaposhwa inoderedza kukweshana panguva yekubvisa pellet, zvichibatsira zvakananga mukubudirira kwesimba kunoonekwa panguva yekugadzira. Hupenyu hwebasa re ring die hwakavakirwa pakuedzwa kweFjordfôr kwe abrasive index hunosvika matani 11,000–12,000 pa die, kuvandudzika kwe40–50% kupfuura nguva yekuchinjana kwedie yemutengi. Drive System uye Energy Efficiency. SZLH508 configuration paFjordfôr inoshandisa mota huru ye160 kW ine gear-driven transmission. Giya rinofambisa rinopa simba repamusoro rekutumira torque (inenge 96–97%) zvichienzaniswa nedzimwe nzira dzinofambiswa nebhandi, richishandura simba rekuisa zvakananga mukuita basa rekuisa pellet uye kuderedza kurasikirwa kwesimba. Pamwe chete nekukakavadzana kwakaderera kubva mumakomba ekufa akaporishwa, dhizaini iyi yekufambisa yakabatsira kudzikiswa kwe14% mukushandiswa kwesimba kwakananga. Kuisa kwakapedzwa panguva yekuvharwa kwekuchengetedza kwemazuva gumi muna Nyamavhuvhu 2025. Chikwata cheHongyang chakatanga basa chakaramba chiri panzvimbo iyi kwemazuva mashanu ekuwedzera kuti chiite miedzo yekugadzira muFjordfôr's three salmon feed formulations (starter, grower, uye finisher), kugadzirisa ma conditioner parameters eresipi yega yega, uye kudzidzisa vashandi veshift vekambani maitiro ekuchinja die uye kuronga kuchengetedza kwekudzivirira. 4. Mhedzisiro Yekugadzira uye Pellet Quality Metrics Mushure memwedzi mina yekushanda nguva dzose, Fjordfôr akanyora zviyero zvinotevera zvekushanda, achienzanisa mutsetse mutsva weHongyang SZLH508 nemidziyo yekare: Kuburitswa kwakawedzera kubva pa6.8 kusvika pa8.5 matani paawa, kuvandudzika kwe25%.
