Kenya ndiyo nyika huru inogadzira mukaka muAfrica iri pasi peSahara kunze kweSouth Africa. Sekureva kwedata rakaburitswa neKenya Dairy Board uye rakaunganidzwa ne governance.co.ke portal, nyika iyi yakagadzira marita emukaka anosvika mabhiriyoni mashanu nemakumi manomwe nematanhatu muna 2024, kubva pamarita mabhiriyoni mashanu nemakumi maviri muna 2022. Chikamu chemukaka chinopa 3–4% yeGDP yenyika uye inenge 12% yeGDP yezvekurima, ichitsigira mhuri dzinopfuura mamiriyoni gumi nesere dzekumaruwa uye ichipa mabasa anopfuura mazana manomwe ezviuru. Pasi pechirongwa cheBottom-Up Economic Transformation Agenda (BETA), hurumende yakaisa chinangwa chikuru chekuwedzera kaviri huwandu hwemukaka kusvika pamarita mabhiriyoni gumi pagore, nekuvandudzwa kwekudya kwemhuka kuchionekwa senzira huru.
Dunhu reNakuru riri muRift Valley muKenya — imwe yenzvimbo dzinonyanya kugadzirwa mukaka munyika. Muna 2024 chete, Nakuru yakagadzira marita emukaka anosvika mamiriyoni mazana matatu negumi nemasere (318 million liters) anokosha KSh 13.9 bhiriyoni, zvichibatsira vanhu vanodarika mazana mashanu ezviuru (500,000) kurarama pamwe chete nekambani yemukaka, sezvakashumwa neOrganic Farm Kenya pamberi peMusangano wekutanga weMilk Value Chain wedunhu wakaitwa munaGunyana 2025. Dunhu iri rine boka guru revarimi vemukaka vadiki nevepakati vanovimba nekudya kwemukaka kwakagadzirwa munharaunda kuti varambe vachiyamwisa.
Bazi rekugadzira chikafu chekutengeserana muKenya rakawedzera nekukurumidza zvichienderana nekukura kwezvinodiwa. Muna Kukadzi 2025, kambani yeDutch De Heus Animal Nutrition yakaraira chigayo chekudya cheKSh 3 bhiriyoni (inenge USD 23 miriyoni) muAthi River chine huwandu hwematani 240,000 pagore, chine mitsetse miviri yepellet imwe neimwe ine chiyero che20 t/h - chiratidzo chakajeka chekufambira mberi kwechikamu ichi. Zvisinei, kune vagadziri vezvikafu vepakati nepakati vanoshanda kunze kweNairobi-Athi River corridor, dambudziko harisi rekuwedzera huwandu hwezvikafu chete; asi kuwana mhando yepellet, kugara kwenguva refu, uye kuvimbika kwekushanda izvo varimi vemukaka vemabhizinesi vari kuwedzera kuda.
Mutengi ari muchidzidzo ichi ikambani yemhuri inogaya chikafu iri makiromita angangoita gumi nemashanu kubva pakati peguta reNakuru. Yakavambwa muna 2012, kambani iyi inogadzira matani angangoita 2,500 echikafu chakasanganiswa pamwedzi, icho 60% yacho inenge iri muchimiro chepellet. Chinosara chinosanganisira chibage chehuku chakasanganiswa nenyama yenguruve, zvese zvinotengeswa muchimiro chehupfu. Mutsetse wepellet yemukaka ndiwo chigadzirwa chepamusoro-soro chekambani uye ndicho chinonyanya kukonzera kukura kwayo.
Zvinhu zvekugadzira dhaka remukaka zvinotorwa mukati memakiromita zana nemakumi maviri: chibage nechibage kubva kuKitale neEldoret, hupfu hwesoya kubva kumafekitori ekugadzira muNakuru Industrial Area, keke rekotoni kubva kumaginneries muLake Victoria basin, uye zvicherwa zvinosanganiswa kubva kuvatengesi vekuNairobi.

Sistimu yeSteam 1.0 t/h boiler (iripo), nzvimbo yekuderedza kumanikidzwa yakagadziridzwa uye vharuvhu yekuchinja
Inotonhorera Hongyang HYSK160 Counterflow Inotonhorera
Kukwanisa kutonhodza 8–10 t/awa (kunoenderana nezvinobuda mumigodhi yepellet)
Kubata Mhepo feni ye centrifugal ye 15 kW ine cyclone separator
Kuburitsa mhepo inotenderera, inochinja-chinja frequency drive
Uinjiniya hwekutumira: giya rinobvisa kuora kwebhandi. HYPM508 inoshandisa giya rinotenderera rakabatana zvakananga nemota huru kuburikidza nekubatanidza kunochinjika, ne ring die yakaiswa pa quill shaft. Iyi configuration inotumira simba nechiyero chekuderedza chinogara chiripo cheinenge 6.3:1, ichipa kumhanya kwe die circumferential kwe6.5–7.0 m/s — mukati mehwindo rakakodzera rema dairy concentrate formulations ane 14–18% crude protein uye 10–12% crude fiber. Kusiyana nemabhandi-driven previous previous, hapana chinhu chekutumira chinogona kurerukirwa ne tension, ambient-temperature-dependent friction coefficient variation, kana abrasive dust ingress. Giya rinovharwa uye mafuta-bath anozorwa, negirazi rekuona ne magnetic drain plug kuti iongororwe nguva dzose.
Kugadzirisa: double-shaft differential action yemafomula ane fiber yakawanda. Mafomula emukaka muKenya anowanzo sanganisira 15–25% yekeke rekotoni kana keke resunflower, zvese izvi zvinopa fiber yechimiro inodzivirira gelatinization. Double-shaft differential conditioner yeHongyang inotarisa izvi nekuchengetedza nguva yekuchengetedza yemasekondi 45–60 pa82–88 °C, zvichibvumira chikamu chestarch kubva muchibage (inenge 30–35% yefomula) kuwana gelatinization yakakwana kuti ishande sechisikirwo. Kurongeka kwepaddle differential - nemukati nekunze shafts zvichitenderera nekumhanya kwakasiyana - kunodzivirira bridgeing uye short-circuit iyo ma single-shaft conditioners anoratidzwa pakugadzira chikafu chine fibrous, chisina hunyoro hwakanyanya.
Kutonhodza kwemhepo inoyerera nepakati: kubatwa kwemhepo inoyerera nepakati kunodzivirira kuvhunduka kwekupisa. HYSK160 inotonhodza inofambisa mhepo inoyerera nepakati pechinhu chinodzika, zvichiita kuti tembiricha iwedzere apo mapellets anopisa (anobuda mupellet mill pa75–85 °C) anosangana nemhepo inodziya zvakanyanya, nepo mapellets anotonhorera ari pedyo negedhi rekuburitsa mvura anosangana nemhepo itsva inoyerera nepakati. Kuchinja kwetembiricha uku kunodzivirira kupwanyika kwepasi kunoitika kana mapellets anopisa akasangana nemhepo inotonhora inoyerera nepakati pechinhu chinotonhora muzvitonhodza zvinoyerera nepakati kana kuti zvakatwasuka. Kuchinja-chinja kwemhepo inoyerera nepakati pechinhu chinoburitsa mhepo kunogadzirisa nguva yekugara kwechigadzirwa kuti chienderane nemazinga akasiyana-siyana ekubudisa kwepellet mill, zvichiita kuti chitonhodza chishande pahurefu hwakakodzera hwemubhedha wese.
Metallurgy yesimbi yeringi inoshandiswa pakugadzira ma "brasive formulations". Keke reKenya rine mbeu yekotoni, zvichienderana nekwakabva, rine fiber yakasara uye huwandu hwezvimedu zvevhu zvinopa simba rekukwesha madziro. Hongyang yakaratidza kuti "X46Cr13 stainless steel ring die" ine vacuum-harded ne "vacuum" ine chiyero chekudzvanya che1:6.5 chegomba re 6.0 mm. Iri giredhi rezvinhu rinowana kuomarara kwenzvimbo ye 58–60 HRC uku richiramba rakasimba zvakakwana kuti rirambe micro-chipping pamaburi ekupinda - nzira yekukundikana yakaonekwa pamaburi ekare, ayo akaomeswa kusvika pa brittle 62–64 HRC.
