1. Mbiri
Kenya ndi dziko lalikulu kwambiri padziko lonse lapansi lomwe limapanga mkaka ku sub-Saharan Africa kunja kwa South Africa. Malinga ndi deta yomwe idatulutsidwa ndi Kenya Dairy Board ndipo idasonkhanitsidwa ndi portal ya governance.co.ke, dzikolo lidapanga malita a mkaka okwana 5.76 biliyoni mu 2024, kuchokera pa malita 5.2 biliyoni mu 2022. Gawo la mkaka limathandizira 3-4% ya GDP ya dziko lonse ndi pafupifupi 12% ya GDP yaulimi, kuthandiza mabanja akumidzi opitilira 1.8 miliyoni ndikupereka ntchito zopitilira 700,000. Pansi pa Ndondomeko Yosintha Zachuma Pang'onopang'ono (BETA), boma lakhazikitsa cholinga chachikulu chochulukitsa kawiri kuchuluka kwa mkaka kufika malita 10 biliyoni pachaka, ndi zakudya zabwino za ziweto zomwe zadziwika kuti ndi njira yoyamba.
Chigawo cha Nakuru chili ku Rift Valley ku Kenya — limodzi mwa madera omwe amapanga mkaka wambiri mdziko muno. Mu 2024 yokha, Nakuru idapanga malita 318 miliyoni a mkaka ofunika KSh 13.9 biliyoni, zomwe zidathandizira anthu opitilira 500,000 pa unyolo wamtengo wapatali wa mkaka, monga momwe Organic Farm Kenya idaneneratu pasadakhale Msonkhano woyamba wa Milk Value Chain womwe udachitika mu Seputembala 2025 m'boma. Chigawochi chili ndi gulu lalikulu la alimi ang'onoang'ono ndi apakatikati omwe amadalira zakudya zopangidwa m'deralo kuti asunge mkaka ukugwira ntchito bwino.
Gawo lopanga chakudya chamalonda ku Kenya lakula mofulumira chifukwa cha kuchuluka kwa anthu omwe akufuna chakudya. Mu February 2025, kampani ya ku Dutch yotchedwa De Heus Animal Nutrition inalamula kuti fakitale yopangira chakudya ya KSh 3 biliyoni (pafupifupi USD 23 miliyoni) ku Athi River ikhale ndi mphamvu zokwana matani 240,000 pachaka, yokhala ndi mizere iwiri ya pellet iliyonse yomwe ili ndi mphamvu zokwana 20 t/h - chizindikiro chodziwikiratu cha njira yopita patsogolo kwa gawoli. Komabe, kwa opanga chakudya odziyimira pawokha omwe amagwira ntchito kunja kwa msewu wa Nairobi-Athi River, vuto si kukulitsa mphamvu zokha; koma kukwaniritsa mtundu wa pellet, kusinthasintha kwa ntchito, komanso kudalirika kwa ntchito zomwe alimi a mkaka amalonda amafunikira kwambiri.
Kasitomala mu kafukufukuyu ndi kampani yopangira chakudya cha mabanja yomwe ili pamtunda wa makilomita 15 kuchokera pakati pa mzinda wa Nakuru. Kampaniyo idakhazikitsidwa mu 2012, ndipo imapanga pafupifupi matani 2,500 a chakudya chamafuta pamwezi, ndipo pafupifupi 60% mwa iwo ndi mkaka wochuluka ngati pellet. Zotsalazo zimakhala ndi ufa wa nkhuku ndi ufa wa nkhumba, zonse zogulitsidwa ngati ufa. Mzere wa pellet wa mkaka ndiye chinthu chapamwamba kwambiri cha kampaniyo ndipo ndiye chimakulitsa kukula kwake.
Zipangizo zopangira mkaka wochuluka zimapezeka mkati mwa mtunda wa makilomita 120: chimanga ndi mbewa za chimanga kuchokera ku Kitale ndi Eldoret, ufa wa soya wochokera ku mafakitale opangira zinthu ku Nakuru Industrial Area, keke ya thonje kuchokera ku mafakitale opangira zinthu ku Lake Victoria, ndi zinthu zopangidwa ndi mchere kuchokera kwa ogulitsa ochokera ku Nairobi. Kuchepa kwa zinthu kumeneku kumapatsa mphero mwayi waukulu poyerekeza ndi omwe akupikisana nawo omwe amadalira zosakaniza za chakudya chochokera kunja, komanso zikutanthauza kuti chinyezi ndi kukula kwa tinthu tating'onoting'ono zimasiyana kwambiri pakati pa magulu - zomwe zimapangitsa kuti mphero ya pellet ikhale yofunikira kwambiri pakukonza ndi kukanikiza.
2. Vuto
Zisanafike chaka cha 2025, mzere wa ma pellet a kasitomala unamangidwa mozungulira ma mphero awiri ochokera kunja ochokera ku India omwe amapangidwa ku India, iliyonse yomwe inali ndi mphamvu ya 6 t/h. Kwa zaka zinayi zogwira ntchito - pomwe ma mpherowa ankagwira ntchito pamodzi matani pafupifupi 75,000 a mkaka wochuluka - mavuto atatu osatha adabuka, iliyonse ikuwononga phindu komanso chidaliro cha makasitomala.
Choyamba: kusakhazikika kwa mphamvu yamagetsi ndi kusokonekera pang'onopang'ono. Dongosolo lotumizira magiya loyendetsedwa ndi lamba linavutika ndi kuchepa kwa mphamvu yamagetsi pamene mphamvu ya lamba inachepa chifukwa cha katundu wokhazikika komanso kutentha kwakukulu kwa malo ozungulira. Nakuru ili pamtunda wa mamita pafupifupi 1,850 pamwamba pa nyanja, ndipo kutentha kwa masana kumafika 28–32 °C nthawi zambiri. Pansi pa izi, ogwira ntchito adanena kuti mphamvu yamagetsi inatsika kuchoka pa 5.5 t/h mpaka kufika pa 3.8 t/h mkati mwa miyezi itatu kuchokera nthawi iliyonse yosinthira lamba. Kusintha lamba kunkafunika miyezi inayi kapena isanu iliyonse, ndipo nthawi iliyonse imatenga maola asanu ndi atatu kapena khumi kuchokera nthawi yopuma yopangira.
Chachiwiri: kupanga zindapusa zambiri. Mafakitale akale ankadalira choziziritsira cha m'badwo wakale chomwe chinali chopingasa chomwe chinali chovuta kuchepetsa kutentha kwa pellet pansi pa 20 °C kuposa momwe zimakhalira nthawi yayitali yopangira. Zindapusa zomwe zinkatuluka mu choziziritsira pa 50–55 °C zinawonetsa kusweka pang'ono pamwamba pamene zinkazizira kwambiri panthawi yosungira, zomwe zinapanga zindapusa zomwe zinkasonkhana m'matumba akuluakulu ndi m'magalimoto otumizira. Kufufuza kwa malo ochitira kafukufuku komwe kunachitika ndi gulu loyang'anira khalidwe la kasitomala kunawonetsa kuti zindapusazo zinalipo kuyambira 6.5% mpaka 11.2% poyerekeza ndi kulemera - kuposa 3% kuposa momwe alimi amkaka ogulitsa m'chigawo cha Rift Valley ankayembekezera. Alimi adadandaula za fumbi looneka m'zakudya zomwe zaperekedwa ndipo adanenanso kuti ng'ombe zawo zinakana pang'ono, zomwe zinasiya zotsalira zosadyedwa m'zitsime zodyera.
Chachitatu: kukwera kwa nthawi yopuma yosakonzekera. Kulephera kwa mabenchi a gearbox, kutopa kwa ring die clamp bolt, ndi kutentha kwambiri kwa injini yoziziritsira pamodzi kuti pakhale kuyimitsidwa kosakonzekera ka 11 pamwezi, kulikonse kumatenga mphindi 45 mpaka kusintha kwathunthu. Mu nyengo yoyamwitsa kwambiri (March-June, pamene kupezeka kwa ziweto kumachepa ndipo kufunikira kwakukulu kukukwera), mphamvu yogwira ntchito ya fakitoleyo inatsika pafupifupi 28% pansi pa zomwe idalonjeza, zomwe zinapangitsa kasitomala kugulitsa ma pellets ku fakitole ya mpikisano yomwe ili pamtunda wa makilomita 80 - pa KSh 3.50 pa kilogalamu iliyonse yomwe idadya pafupifupi malire onse a mzere wa ma pellets a mkaka.
Chikalata chokonzera zinthu cha kasitomala kwa miyezi 12 isanafike nthawi yosinthira zida chinalemba zinthu 127 zosakonzedwa, nthawi yapakati pakati pa kulephera (MTBF) ya maola 65 ogwirira ntchito, ndi ndalama zogulira zinthu pachaka zomwe zimafanana ndi 18% ya mtengo wa mabuku omwe ma pellet mills adatsika mtengo.
3. Yankho la Hongyang
Mu Seputembala 2024, atawunika malingaliro ochokera kwa ogulitsa zida atatu — m'modzi waku Europe, m'modzi waku India (chitsanzo cholowa m'malo mwa yemwe analipo), ndi Hongyang Feed Machinery (Liyang, China) — kasitomala adasankha lingaliro la Hongyang. Zinthu zofunika kwambiri, monga momwe adafotokozera mkulu woyang'anira fakitole, zinali: (a) kutumiza mwachindunji kwa HYPM508 komwe kumayendetsedwa ndi giya, komwe kumachotsa kutsetsereka kwa lamba ngati njira yolephera; (b) njira yoziziritsira yolumikizidwa, yomwe lingaliro la ku Europe lidalipira mtengo wokwera ndi 40% ngati chowonjezera chodziyimira pawokha; ndi (c) kufunitsitsa kwa Hongyang kupereka chithandizo chogwirira ntchito pamalopo ndi gulu la mainjiniya awiri kwa masiku 14.
Kapangidwe kake kamene kaikidwa ndi motere:

Kutulutsa chotseka chozungulira, choyendetsa ma frequency osinthasintha
Uinjiniya wa ma transmission: giya loyendetsa limachotsa kuwonongeka kwa lamba. HYPM508 imagwiritsa ntchito giya loyendetsa lozungulira lomwe limalumikizidwa mwachindunji ndi mota yayikulu kudzera mu cholumikizira chosinthika, ndi mphete yolumikizira yomwe imayikidwa pa quill shaft. Kapangidwe kameneka kamatumiza mphamvu pa chiŵerengero chocheperako cha pafupifupi 6.3:1, kupereka liwiro lozungulira la die la 6.5–7.0 m/s — mkati mwa zenera labwino kwambiri la ma formula a mkaka okhala ndi 14–18% crude protein ndi 10–12% crude fiber. Mosiyana ndi ma precursors oyendetsedwa ndi lamba, palibe chinthu chotumizira chomwe chimatha kupumula mphamvu, kusintha kwa friction coefficient komwe kumadalira kutentha, kapena kulowerera kwa fumbi. Chikwama cha giya chimatsekedwa ndipo chimapakidwa mafuta, ndi galasi lowonera ndi pulagi ya magnetic drain kuti chiziyang'aniridwa nthawi zonse.
Kukonza: Kusiyanitsa kwa double-shaft kwa mitundu yokhala ndi ulusi wambiri. Mitundu yokhala ndi mkaka wambiri ku Kenya nthawi zambiri imakhala ndi keke ya 15–25% ya mbewu ya thonje kapena keke ya mpendadzuwa, zonse ziwiri zomwe zimapangitsa kuti ulusi wa kapangidwe kake usamalowe mu gelatinization. Chokometsera cha Hongyang cha double-shaft differential conditioner chimagwira ntchito imeneyi mwa kusunga nthawi yosungira ya masekondi 45–60 pa 82–88 °C, zomwe zimathandiza kuti gawo la starch kuchokera ku chimanga (pafupifupi 30–35% ya kapangidwe kake) likhale ndi gelatinization yokwanira kuti ligwire ntchito ngati chomangira chachilengedwe. Kapangidwe ka differential paddle - ndi shafts zamkati ndi zakunja zikuzungulira pa liwiro losiyana - kumalepheretsa kulumikiza ndi kufupika kwa circuitry komwe ma single-shaft conditioners amawonetsa akamakonza chakudya chokhala ndi ulusi komanso chinyezi chochepa.
Kuziziritsa kwa mpweya wozungulira: kukhudzana ndi mpweya wozungulira kumaletsa kutentha kwambiri. Choziziritsira cha HYSK160 chozungulira chimadutsa mpweya wozungulira mmwamba kudzera mu mzere wazinthu zomwe zimatsika, zomwe zimapangitsa kuti kutentha kukhale koyenera pomwe ma pellet otentha kwambiri (otuluka mu mphero ya pellet pa 75–85 °C) amakumana ndi mpweya wotentha kwambiri, pomwe ma pellet ozizira kwambiri pafupi ndi chipata chotulutsira madzi amakumana ndi mpweya watsopano wozungulira. Kusintha kwa kutentha kozungulira kumeneku kumaletsa kusweka kwa pamwamba komwe kumachitika pamene ma pellet otentha akumana ndi mpweya wozizira wozungulira m'malo ozizira kapena ozungulira. Kuyendetsa kwa ma frequency osinthasintha pa airlock yozungulira yotulutsira madzi kumasintha nthawi yogona ya chinthu kuti igwirizane ndi kuchuluka kwa kutulutsa kwa pellet, kuonetsetsa kuti choziziritsiracho chikugwira ntchito pamlingo woyenera pamlingo wonse wa throughput.
Kukonza zitsulo zopangira zinthu zoduladula. Keke ya mbewu ya thonje ya ku Kenya, kutengera komwe idachokera, ili ndi ulusi wotsalira wa linter ndi kuchuluka kwa tinthu ta dothi tomwe timathandizira kusweka kwa khoma. Hongyang adatchula die ya chitsulo chosapanga dzimbiri ya X46Cr13 yolimba ndi vacuum yokhala ndi chiŵerengero chogwira ntchito cha 1:6.5 pa dzenje la 6.0 mm. Kuchuluka kwa zinthuzi kumakwaniritsa kuuma kwa pamwamba pa 58-60 HRC pomwe kumasunga kulimba kokwanira kuti kupewe kusweka kwa micro-chipping m'malo olowera mabowo - njira yolephera yomwe idawonedwa pama die am'mbuyomu, omwe adawumitsidwa mpaka 62-64 HRC yofooka.
4. Zotsatira
Mzere wa Hongyang unayamba kugwira ntchito mu Januwale 2025. Gulu loyang'anira khalidwe la kasitomala linachita pulogalamu yowunikira magwiridwe antchito ya masiku 90, kuyeza zizindikiro zazikulu poyerekeza ndi deta yoyambira kuchokera ku miyezi isanu ndi umodzi yomaliza ya mzere wakale. Zotsatira zake zafotokozedwa mwachidule pansipa.

Chiyerekezo cha Kulimba kwa Pellet pa 96.8%. Zotsatira za Holmen zoyesa za 96.8% pambuyo pa masekondi 30 zikuyimira umphumphu wa pellet mu gawo lapamwamba la chakudya cha mkaka chogulitsidwa padziko lonse lapansi. Kuphatikiza kwa chowongolera cha double-shaft chomwe chimapangitsa kuti gelatinization ikhale yofanana komanso choziziritsira chotsutsana ndi kutentha ndi njira yayikulu. Kwa alimi a mkaka omwe ali mu radius yogawa ya kasitomala, izi zikutanthauza kuti chakudya choyera kwambiri sichinakanidwe chifukwa cha chindapusa chochulukirapo m'miyezi isanu kuyambira pomwe idayamba kugwira ntchito, komanso malipoti a mbiri ya kuchepa kwa zotsalira za chakudya.
Kugwiritsa ntchito mphamvu kwachepetsedwa ndi 19.2%. Chiwerengerochi chikuwonetsa zotsatira zonse za giya yoyendetsedwa ndi giya (pafupifupi 5% ya phindu la mphamvu poyerekeza ndi lamba woyendetsedwa bwino komanso mpaka 12% poyerekeza ndi lamba wosweka), kuphatikiza kuchotsa chotengera chosiyana cha choziziritsira ndi fan yobwezeretsanso, zomwe pamodzi zimadya pafupifupi 7.5 kW. Pa kuchuluka kwa kupanga kwa mphero ya mkaka pafupifupi matani 1,500 pamwezi, ndalama zosungidwa za 4.3 kWh/t zikufanana ndi kuchepetsa mtengo wamagetsi pafupifupi KSh 130,000 pamwezi - zofanana ndi malipiro a wogwiritsa ntchito wina wowonjezera.
5. Ndemanga za Makasitomala
Mtsogoleri wamkulu wa fakitaleyi, polankhula paulendo wake woyendera malo mu Meyi 2025, adapereka ndemanga iyi:
"Chigayo cha ma pellet choyendetsa magiya ndi choziziritsira cha counterflow zasintha kwambiri momwe timakonzera kupanga. Pansi pa dongosolo lakale, ndinali kukonza nthawi yogwiritsira ntchito makina — kukonza mawindo okonzera, kukonza bajeti ya ma lamba osintha, ndikupepesa kwa alimi akafika mochedwa. Tsopano makinawo amagwira ntchito motsatira dongosolo lopangira, osati mosiyana. Alimi athu a mkaka amatiuza kuti ma pellet afika ali bwinobwino ndipo ng'ombe zawo zimatsuka zimbudzi. Imeneyo ndiye ndemanga yofunika kwambiri kwa ife."
Woyang'anira ntchito yokonza zinthu anawonjezera kuti: “Choziziritsira chotsutsana ndi madzi ndi ngwazi yosayamikirika. Tinkadandaula za nkhungu nthawi yamvula chifukwa choziziritsira chakale chinkasiya zinthu zofunda komanso zonyowa. Mvula yayitali ya chaka chino — kuyambira mu Marichi mpaka Meyi — sitinapeze phindu lililonse chifukwa cha nkhungu. Kutentha kotuluka mu choziziritsira sikunapitirire 30 °C ngakhale masiku omwe mlengalenga unafika 30 °C. Kusasinthasintha kumeneko ndi komwe makasitomala athu amaona.”
Gulu lokonza linanena kuti mphete yomangira yomwe idayikidwa panthawi yoyambitsa ntchito inali itasonkhanitsa maola pafupifupi 6,200 ogwirira ntchito pofika kumapeto kwa Meyi 2025, ndipo kuwonongeka kwa dzenje lomangira kunali 0.12 mm — mkati mwa malire a ntchito omwe wopanga adalimbikitsa a 0.25 mm, zomwe zikusonyeza kuti nthawi yogwiritsira ntchito mpheteyi iyenera kupitirira maola 10,000.
6. Mapeto
Nkhani ya mphero yodyetsera mkaka ku Nakuru ikuwonetsa momwe zinthu zimachitikiranso pakati pa opanga zakudya zapakatikati ku East Africa: kusintha kuchoka pa mphero yodyetsera mkaka kupita ku mphero yodyetsera mkaka yoyendetsedwa ndi lamba kupita ku mphero yoyendetsedwa ndi gear, kuphatikiza ndi kuziziritsa kwa counterflow, kumabweretsa kusintha kwakukulu pakukhazikika kwa zotulutsa, mtundu wa pellet, ndi kapangidwe ka ndalama zogwirira ntchito komwe kumapitirira kupititsa patsogolo pang'onopang'ono.
Pa Hongyang Feed Machinery, pulojekitiyi inasonyeza kuthekera kwa kampaniyo kupereka njira yonse yopangira ma pellet — mphero ya ma pellet, chowongolera mpweya, ndi choziziritsira — monga phukusi lophatikizidwa ndi chithandizo chopangira ma pellet pamalo ovuta kugwira ntchito. Nthawi yopangira ma pellet ya masiku 14 inatha mkati mwa nthawi yake, ndipo mzerewo unafika pa 95% ya mphamvu yovomerezeka pofika tsiku la 11 la kupanga.
