Nthawi zambiri anthu amatha kuwoneka akuwotcha zotsatira za ntchito yawo mumphika wokulirapo pamoto wotseguka ku Ethiopia, komwe kumadziwikanso kuti ndiko komwe khofi anabadwira.
Tanena izi, owotcha khofi ndi zida zofunika kwambiri zomwe zimathandiza kusintha khofi wobiriwira kukhala wonunkhira, nyemba zowotcha zomwe zimathandizira bizinesi yonse.
Msika wowotcha khofi, mwachitsanzo, ukuyembekezeka kukhala wamtengo wapatali $337.82 miliyoni mu 2021 ndipo ukuyembekezeka kukula mpaka $521.5 miliyoni pofika 2028.
Makampani a khofi asintha pakapita nthawi, monganso makampani ena onse.Mwachitsanzo, owotcha ng'oma omwe amafala kwambiri pabizinesi yamakono adatengera njira zakale zowotchera nkhuni zomwe zidagwiritsidwa ntchito ku Ethiopia.
Ngakhale kuti zowotcha khofi zowotcha mpweya kapena zoziziritsa kukhosi zidayamba kupangidwa m'ma 1970, kuwotcha ng'oma ndi njira yakale, yodziwika bwino.
Ngakhale kuwotcha mpweya kwakhala kukugwiritsidwa ntchito kwa zaka makumi asanu, okazinga ambiri tsopano akuyesa njirayi chifukwa imatengedwa kuti ndi yatsopano.
Kodi khofi amawotcha bwanji mpweya?
Mike Sivets, katswiri wamakina pophunzitsidwa, akuyamikiridwa kuti adapanga lingaliro la khofi wowotcha mpweya zaka zoposa 50 zapitazo.
Mike adayamba ntchito yake pantchitoyi pogwira ntchito ku General Foods'instant khofi division, koma sanapange chowotcha chamadzi mpaka atasiya bizinesi ya khofi.
Akuti atapatsidwa ntchito yokonza mafakitale a khofi wanthawi yomweyo, anayamba kuchita chidwi ndi anthu okazinga khofi.
Panthawiyo, okazinga ng'oma okha ndi omwe ankawotcha khofi, ndipo kafukufuku wa Mike adawonetsa zolakwika zambiri zomwe zidachepetsa kwambiri zokolola.
Pambuyo pake Mike adapita kukagwira ntchito m'malo opangira polyurethane, komwe adapanga njira yopangira bedi lamadzimadzi kuti achotse mamolekyu amadzi m'mafupa a magnesium.
Akatswiri a ku Germany anachita chidwi ndi ntchito yake chifukwa cha zimenezi, ndipo posakhalitsa panayambika kukambirana za kugwiritsa ntchito njira yomweyi powotcha khofi.
Zimenezi zinatsitsimulanso chidwi cha Mike pa khofi, ndipo anathera nthaŵi ndi nyonga zake kupanga makina oyamba owotchera mpweya, chowotchera khofi pabedi lamadzimadzi.
Ngakhale zidamutengera Mike zaka zambiri kuti apange mtundu wogwirira ntchito womwe ukhoza kukulitsa kupanga, kapangidwe kake ka patenti kanali patsogolo kwambiri pamakampani pafupifupi zaka zana.
Zowotcha zamadzimadzi, zomwe zimadziwikanso kuti zowotcha mpweya, zimatenthetsa nyemba za khofi podutsa mpweya wodutsa.Dzina lakuti "kuwotcha pabedi" linapangidwa chifukwa nyemba zimaleredwa ndi "bedi" la mpweya.
Masensa ambiri omwe amapezeka mu chowotcha wamba amakulolani kuti muwone ndikuwongolera kutentha kwa nyemba.Kuphatikiza apo, zowotcha mpweya zimakuthandizani kuti muzitha kuwongolera zinthu monga kutentha ndi kutuluka kwa mpweya kuti muwotche zomwe mukufuna.
Kodi kuwotcha mpweya ndikoposa bwanji kuwotcha ng'oma?
Momwe nyemba zimatenthedwera ndi kusiyana kwakukulu pakati pa kuwotcha mpweya ndi kuwotcha ng'oma.
Mu ng'oma yodziwika bwino kwambiri, khofi wobiriwira amaponyedwa mu ng'oma yozungulira yomwe yatenthedwa.Pofuna kutsimikizira kuti chowotchacho ndi chofanana, ng'oma imazungulira nthawi zonse.
Kutentha kumaperekedwa ku nyemba mu chowotcha ng'oma kudzera mu kuphatikiza kwa 25% conduction ndi 75% convection.
M'malo mwake, kuwotcha mumlengalenga kumawotcha nyemba kudzera mu convection.Mpweya umenewo, kapena kuti “bedi,” umapangitsa kuti nyembazo zikhalebe m’mwamba ndipo zimatsimikizira kuti kutentha kumamwazikana mofanana.
M'malo mwake, nyembazo zimakutidwa ndi mpweya wotenthedwa bwino.
Kusiyana kwa kukoma kungakhale chimodzi mwazinthu zomwe zimayendetsa kukula kwa owotcha mpweya mu gawo lapadera la khofi.
Ndikofunika kukumbukira kuti amene amawotcha khofi amakhudza kwambiri kukoma kwake.
Koma chifukwa makinawo amachotsa mankhusu akamawotcha, amakhala ndi mwayi wochepa woyaka, kuwotcha mpweya sikungabweretse kukoma kwa fodya.
Kuphatikiza apo, poyerekeza ndi owotcha ng'oma, owotcha mpweya amakonda kutulutsa khofi yemwe ali ndi acidic mu kukoma.
Poyerekeza ndi zowotcha ng'oma, zowotcha mpweya nthawi zambiri zimapanga zowotcha zosasinthasintha zomwe zimakonda kutulutsa mawonekedwe amtundu umodzi.
Kodi khofi wowotcha mpweya amakuchitirani chiyani
Kupatula kukoma ndi kununkhira kwake, zowotcha ng'oma wamba ndi zowotcha mpweya zimasiyana wina ndi mzake.
Kusiyanasiyana kwakukulu kwa magwiridwe antchito kumathanso kukhala ndi chikoka chachikulu pakampani yanu.
Imodzi ndi nthawi yowotcha, mwachitsanzo.Khofi akhoza kuwotchedwa mu chowotcha chamadzimadzi pafupifupi theka la nthawi yomwe zimatengera muwotcha wamba.
Makamaka kwa okazinga khofi apadera, kuwotcha kwakufupi sikungapange mankhwala osayenera, omwe nthawi zambiri amapatsa khofi fungo losavomerezeka.
Chowotcha pabedi lamadzimadzi chingakhale chisankho chabwino kwambiri kwa okazinga omwe akuyang'ana kuti apereke chithunzi cholondola cha makhalidwe a nyemba.
Chachiwiri ndi mankhusu, chinthu chosapeŵeka cha kuwotcha chomwe chimabweretsa ngozi kwa kampani yanu.
Choyamba, imatha kuyaka kwambiri ndipo ikhoza kugwira moto ngati siigwiridwa mosamala, kuletsa ntchito yonseyo.Kupanga utsi mwa kuwotcha mankhusu ndi chinthu china choyenera kuganizira.
Owotcha pabedi amadzimadzi amachotsa mankhusu mosalekeza, ndikuchotsa kuthekera kwa kuyaka kwa mankhusu kuti apangitse khofi wokoma kwambiri.
Chachitatu, pogwiritsa ntchito thermocouple, zowotcha mpweya zimawerengera bwino kutentha kwa nyemba.
Izi zimakupatsirani chidziwitso chowonekera komanso cholondola chokhudza nyemba, kukuthandizani kuti mupangenso mbiri yowotcha yomweyi.
Makasitomala apitilizabe kugula kuchokera kwa inu ngati kampani ngati malonda anu ali ofanana.
Ngakhale kuti owotcha ng'oma amatha kuchita zomwezo, kuchita zimenezi kaŵirikaŵiri kumafuna kuti wowotcherayo akhale ndi chidziwitso chochuluka ndi ukatswiri.
Poyerekeza ndi zowotcha ng'oma wamba, zowotcha mpweya sizingafune kusintha kwakukulu pamalo omwe muli pano pokonza ndi kukonza.
Zowotcha mpweya zimatha kutsukidwa mwachangu kuposa zowotcha ng'oma, ngakhale zida zonse ziwirizi ziyenera kusamalidwa ndi kutsukidwa.
Imodzi mwa njira zowotchera bwino zachilengedwe ndi kuwotcha mpweya, komwe kumatenthetsa mwanzeru nyemba za khofi pogwiritsa ntchito kutentha komwe kumachitika powotcha.
Pochepetsa kufunika kotenthetsanso ng'oma pakati pa magulu, ndizotheka kupulumutsa ndikubwezeretsanso mphamvu ndikuchepetsa mpweya woipa wa carbon dioxide ndi 25%.
Mosiyana ndi zowotcha ng'oma wamba, zowotcha mpweya safuna afterburner, zomwe zingakuthandizeni kusunga mphamvu.
Kugula zopangira khofi zobwezerezedwanso, zokometsedwa, kapena zowola komanso makapu otengera khofi ndi njira ina yopititsira patsogolo mbiri ya kampani yanu yowotcha.
Ku CYANPAK, timapereka mayankho osiyanasiyana opaka khofi omwe ndi 100% omwe amatha kubwezeredwanso komanso opangidwa kuchokera kuzinthu zongowonjezwdwanso ngati pepala la kraft, pepala la mpunga, kapena ma LDPE amitundu yambiri okhala ndi PLA yamkati ya Eco-friendly.
Kuphatikiza apo, timapatsa owotcha athu ufulu wakulenga powalola kupanga zikwama zawo za khofi.
Mutha kupeza thandizo kuchokera kwa ogwira ntchito yopanga khofi kuti abwere ndi phukusi loyenera la khofi.Kuonjezera apo, timapereka matumba a khofi osindikizidwa omwe ali ndi nthawi yochepa yosinthira maola 40 ndi nthawi yotumiza maola 24 pogwiritsa ntchito luso lamakono losindikiza digito.
Owotcha ang'onoang'ono omwe akufuna kukhala achangu pomwe akuwonetsa chizindikiritso chamtundu komanso kudzipereka kwa chilengedwe amathanso kutenga mwayi pazambiri zotsika mtengo za CYANPAK (MOQs).
