Mwina mwadina kachidutswa kakang'ono kameneka pa thumba lanu la khofi kuti mununkhize nyemba. Koma dzenje limenelo sililipo kuti mununkhize. Lilipo chifukwa popanda ilo, thumba lanu lidzaphulika.
Matumba a khofi ali ndi ma valve otulutsa mpweya omwe amatulutsa mpweya wa carbon dioxide pamene akutseka mpweya. Nyemba zokazinga zimatulutsa mpweya wambiri wa CO2 kwa maola 24-72 mutakazinga.—Kutuluka kwa thumba nthawi zambiri kumachitika pamene makampani ambiri amatseka matumba awo. Valavu imaletsa kuwonongeka kwa thumba panthawi yovutayi, koma pokhapokha ngati zomwe valavuyo ikufuna zikugwirizana ndi nthawi yanu yokazinga mpaka kulongedza komanso kulemera kwa chodzaza.
Makambirano ambiri okhudza ma CD amayang'ana kwambiri mitundu ya ma valve ndi zipangizo. Koma ndawona ma valve apamwamba akulephera chifukwa ma roaster amadzaza matumba maola asanu ndi limodzi mutawotcha m'malo mwa khumi ndi awiri. Funso si valavu yoti mugwiritse ntchito, koma nthawi yoti mutseke mutazizira. Pitirizani kuwerenga kuti mudziwe chifukwa chake nthawi nthawi zonse imakhala yofunika kwambiri kuposa zofunikira.
Kodi n’chiyani kwenikweni chikuchitika mkati mwa thumba la khofi lotsekedwa?
Kuwotcha khofi wobiriwira kumasintha nyemba zake pogwiritsa ntchito mankhwala amphamvu. Kutentha kumawononga chakudya chophatikizana ndi mapuloteni, zomwe zimapangitsa kuti pakhale zinthu zambirimbiri zosakhazikika.
Chomwe chimapangidwa ndi carbon dioxide. Nyemba zikamawotcha, zimasunga CO2 mkati mwa kapangidwe ka maselo awo. Nyemba zikachotsedwa pamoto, nthawi yomweyo zimayamba kutulutsa mpweyawu. Kuchuluka kwa mpweya kumadalira kuchuluka kwa wowotcha komanso kutentha kwa malo ozungulira. Zowotcha zakuda zimatulutsa mpweya mwachangu kuposa zowotcha zopepuka, chifukwa kutentha kwakukulu kumapanga kapangidwe ka nyemba zokhala ndi mabowo ambiri.
Malo Oopsa: Maola 24–72
Nyemba zokazinga kumene zimatulutsa 60–80% ya CO2 yonse mkati mwa masiku atatu. Mpweya woipa umatuluka kwambiri m'maola 24 oyambirira. Chikwama cha nyemba zonse cha 350g chingapangitse kuti pakhale kupanikizika kokwanira kuti ziswe mipata kapena kusokoneza filimuyo.
Ndaona anthu ophika nyama akutaya zinthu zonse ponyalanyaza nthawi imeneyi. Kasitomala mmodzi anatseka matumba 1,000 maola anayi ataphika, zomwe zinachititsa kuti matumba 30% awonongeke mkati mwa maola 48.
Kuchuluka kwa gasi kumasiyana kwambiri malinga ndi mbiri ya nyama yokazinga:
- •Kuwotcha pang'ono: kutulutsidwa pang'onopang'ono kwa masiku 5-7
- •Kuwotcha kwapakati: kutulutsidwa pang'ono kwa masiku 3-5
- •Kuwotcha kwakuda: kutulutsidwa kophulika kwa maola 24-48
Valavu yanu iyenera kukhala yokhoza kuthana ndi kuchuluka kwa madzi omwe amatuluka molingana ndi kuchuluka kwa madzi omwe mumawotcha. Ma "valavu a khofi" wamba saganizira kusiyana kumeneku.
Chifukwa chiyani mpweya umawononga ubwino wa khofi
Mpweya wa okosijeni umayambitsa kusintha kwa okosijeni komwe kumaphwanya mankhwala onunkhira. Mafuta omwe ali mu mafuta a khofi amakhala otupa akamayikidwa mumlengalenga. Njirayi imathamanga kwambiri kutentha kwa chipinda.
Kuba kumayamba mkati mwa maola ochepa kuchokera pamene mpweya walowa. Mudzaona kutayika kwa kukoma ngakhale nkhungu isanawonekere. Valavuyi idapangidwa osati kuti itulutse CO2 yokha komanso kuti ipange chotchinga cha mbali imodzi chomwe chimatseka mpweya wozungulira kuti usalowe, pomwe kupanikizika kwamkati kumakakamiza mpweya kutuluka.
Kupaka kwachikhalidwe kopanda ma valve kumakukakamizani kusankha: kutseka nthawi yomweyo ndikuyika pachiwopsezo cha kuphulika, kapena kudikira masiku 5-7 kuti muchotse mpweya wonse ndikusiya kutsitsimuka. Palibe njira iliyonse yomwe ili yoyenera kugwiritsidwa ntchito pamalonda.
Kodi ma valve ochotsa mpweya m'njira imodzi amagwira ntchito bwanji?
Makina a valavu amagwiritsa ntchito diski yopyapyala ya elastomer yomwe yakanikiza pa maziko obowoka. Kupanikizika kwamkati mwa silinda, komwe kumachitika chifukwa cha kuchuluka kwa CO2, kumakweza pang'ono diskiyo. Gasi amatuluka kudzera m'mabowo. Kupanikizika kwamkati kukatsika, diskiyo imabwerera pamalo ake oyamba, ndikutseka mpweya kuti usalowe.
Ma valve okhazikika amatsegulidwa pa kuthamanga kwamkati kwa 0.5–1.5 psi. Zimatseka nthawi yomweyo mphamvu ikakhala yofanana. Zipangizo za elastomer ziyenera kukhala zosinthasintha kutentha kuyambira -20°F mpaka 120°F kuonetsetsa kuti zinthuzo zili bwino panthawi yonyamula ndi kusungira.
Kuyika ma valavu ndikofunikira kwambiri kuposa momwe mukuganizira.
Makampani ambiri amaika ma valve kulikonse kutsogolo kwa thumba. Komabe, malo awo amakhudza kwambiri magwiridwe antchito. Nthawi zonse ndimalimbikitsa kuyika ma valve kutengera kulemera kwa kudzaza ndi komwe thumba likuyang'ana.
Pa matumba oimikapo okhala ndi ma gussets apansi, valavu iyenera kuyikidwa pansi pa msoko 2.5-5 cm, zomwe zimapangitsa kuti mpweya ukhale wambiri. Matumba okhala ndi ma gussets am'mbali amafuna kuti ma vavu azikhala pakati pa gulu lakutsogolo kuti apewe kusintha kwa kukongola chifukwa cha kutulutsidwa kwa CO2.
Kugwirizana ndi wopanga zinthu wapadera, yemwe anasuntha ma valve ndi 7.5 cm pansi pa matumba okhala ndi pansi panthaka, kunachepetsa madandaulo a makasitomala okhudza "matumba otupa" ndi 85%.
Valavu iyenera kupereka kuchuluka kwa madzi koyenera kulemera kwa chodzaza:
- Matumba 8-12 oz: m'mimba mwake wa valavu ndi 8 mm
- Matumba a 1-2 lb: valavu ya 10 mm kuti ikhale ndi mphamvu zambiri
- Matumba a nyemba okwana mapaundi 5: makina awiri a ma valve kapena mainchesi 15 mm
Kugwiritsa ntchito ma valve ang'onoang'ono kumabweretsa kupanikizika kumbuyo, zomwe zimapangitsa kuti chitsekocho chikhale chovuta. Ma valve akuluakulu ndi okwera mtengo koma sapereka mphamvu yowonjezera.
Nkhani Zogwirizana ndi Zinthu Zomwe Palibe Amene Amalankhulapo
Ma valve amamangiriridwa ku filimu yopaka pogwiritsa ntchito zomatira zotenthetsera kapena zomatira zomatira. Kapangidwe ka filimuyo kayenera kuonetsetsa kuti valavuyo imamatira popanda kulekanitsidwa. Ndaona ma flaps akuchotsa matumba chifukwa opanga amagwiritsa ntchito zomatira zomwe sizigwirizana ndi mafilimu otchinga.
Pa matumba a khofi opangidwa ndi manyowa, kusankha ma valavu ndikofunikira kwambiri. Ma valavu achikhalidwe okhala ndi PET sawonongeka m'malo opangira manyowa. Mukufuna ma valavu opangidwa ndi ma polima opangidwa ndi manyowa omwe amakwaniritsa zofunikira zobwezeretsanso filimu yanu.
Mapangidwe obwezerezedwanso amakumana ndi zovuta zina. Vavu iyenera kuchotsedwa mosavuta panthawi yobwezerezedwanso, apo ayi idzadetsa gulu lonselo. Chifukwa chake, ndikupangira kuti valavuyo iikidwe kuti ikhale yosavuta kwa ogula kuchotsa asanabwezerezenso.
Kodi ndi liti pamene mukufunikadi valavu yochotsera mpweya?
Makapisozi ogwiritsidwa ntchito kamodzi kokha ndi mapaketi ang'onoang'ono operekedwa kamodzi kokha nthawi zambiri samakhala ndi ma valve. Mfundo ndi yomveka bwino: ogula amapanga zinthuzi nthawi yomweyo akangotsegula. Nthawi yogwiritsira ntchito pashelefu imayesedwa m'masiku, osati masabata.
Ma valve amafunikira zinthu zitatu zikakwaniritsidwa: chinthucho ndi nyemba yonse (osati yophwanyika), kukula kwa paketiyo ndi koposa ma ounces 8 (230 ml), ndipo nthawi yosungiramo khofi imapitirira milungu iwiri. Khofi wophwanyika amachotsa mpweya mwachangu ndi 50% kuposa nyemba yonse, koma mpweya wonse ndi wochepa chifukwa njira yopera imatulutsa CO2 yogwidwa musanapake.
Kusankha Nthawi Yokazinga ndi Kupaka
Apa ndi pomwe anthu ambiri owotcha nyama amalakwitsa kwambiri. Amafunsa kuti, "Ndi valavu iti yomwe ndiyenera kugwiritsa ntchito?" asanayankhe kuti, "Ndi liti pamene ndiyenera kutseka matumba ndikawotcha nyama?"
Ngati mungathe kudikira maola 12-24 musanatseke, ma valve ang'onoang'ono komanso otsika mtengo angagwiritsidwe ntchito chifukwa mphamvu ya peak pressure yatuluka kale mwachilengedwe. Komabe, ngati mukufuna kutseka matumba mkati mwa maola 4-6 (omwe nthawi zambiri amapangidwa ndi anthu ambiri), muyenera ma valve akuluakulu opangidwa kuti aziyenda bwino.
Nthawi zonse ndimafunsa makasitomala kuti, "Kodi ndondomeko yanu yeniyeni yopangira ndi yotani?" Wophika khofi amene amakonza ma batches maola 8 aliwonse amafunika njira yosiyana ndi munthu amene amaphika khofi kuyambira Lolemba mpaka Lachitatu kuti agulitsidwe pamsika wa alimi kumapeto kwa sabata.
Kukambirana ndi wowotcha yemwe adachepetsa mtengo wa ma valavu ndi 40% pongosintha nthawi yoziziritsira kuti alole nthawi yopumula maola 18 asanapake.
Zinthu zokhudza malo ndi nyengo
Kutalika kwa mpweya kumakhudza kuchuluka kwa mpweya wotuluka m'thupi. Nyemba zokazinga pamalo okwera mamita 1,500 zimatulutsa CO2 mwachangu kuposa zomwe zimakazinga pamalo okwera nyanja, chifukwa kutsika kwa mpweya kumapangitsa kuti mpweya ukhale wochepa kwambiri.
Kusintha kwa kutentha panthawi yoyendera kumakhudza kwambiri kutseka ma valve. Ma phukusi akasunthidwa kuchokera ku zidebe zozizira kupita ku malo osungiramo zinthu otentha, pamakhala kusiyana kwa kuthamanga kwa mpweya komwe kungawononge umphumphu wa ma valve. Ndikupangira kuyesa zitsanzo zopakidwa pansi pa mikhalidwe yosinthasintha kutentha musanayambe kupanga kwakukulu.
Chinyezi sichimakhudza mwachindunji kutuluka kwa CO2, koma chimakhudzanso zinthu zotchinga za filimuyi. Chinyezi chochuluka chingayambitse kulephera kwa chitseko pa malo olumikizira ma valavu ngati mugwiritsa ntchito zomatira zochokera m'madzi m'malo motseka kutentha.
Kodi ndi zolakwa zazikulu ziti zomwe makampani amapanga akamagwiritsa ntchito ma valve a khofi?
Cholakwika chofala kwambiri ndikuwona ma valve onse ngati zinthu zosinthika. Ndawona makampani akusintha ogulitsa ma valve kuti asunge $0.02 pa unit iliyonse, koma kutaya madola masauzande ambiri chifukwa cha zolakwika pakulongedza.
Kugwira ntchito kwa mavavu kumadalira zinthu zisanu ndi chimodzi: mbiri yokazinga, kuchuluka kwa nyemba, kulemera kwa kudzaza, nthawi yotseka, kutentha kosungira, ndi nthawi yomwe ikuyembekezeka yosungiramo zinthu. Kusintha kusintha kulikonse kumafuna kuwunikanso momwe mavavu amagwirira ntchito.
Nthano ya "Chikwama Chopumira"
Ophika nyama ena amakoka "matumba opumira" popanda kumvetsetsa kuchuluka kwenikweni kwa mpweya womwe amatulutsa. Amayitanitsa ma valve opangidwira tiyi kapena zonunkhira—zinthu zomwe zimatulutsa mpweya wochepa—kenako n’kudabwa chifukwa chake matumba awo a khofi akadali kuphulika.
Khofi imatulutsa CO2 yochulukirapo ka 5-10 kuposa khofi wouma wamba. Valavu yanu iyenera kupirira kuchuluka kwenikweni, osati mawu otsatsa akuti "khofi imafunika kupuma."
Ndikupangira mayeso osavuta: sungani gulu loyesera, yesani matumba mukamalongedza, ndikuziyezanso patatha maola 24, 48, ndi 72. Kuchepa kwa kulemera kumasonyeza kuchuluka kwa CO2 komwe kumatuluka. Deta iyi imatsimikizira molondola kuchuluka kwa madzi omwe valavu yanu iyenera kuthana nawo.
Kunyalanyaza Kusintha kwa Chuma Cholembetsa
Msika ukugawikana, kuchoka pa kugula zinthu zambiri kupita ku kutumiza zinthu zochepa komanso pafupipafupi. Izi zimasintha kwambiri kapangidwe kabwino ka ma CD.
Ma micro-batch roasters tsopano amafunika ma valve system otsekekanso chifukwa ogula amafuna matumba a ma ounces 8 omwe angathe kudya mkati mwa masiku 5-7, osati matumba a mapaundi awiri omwe amakhala otseguka kwa milungu ingapo. Komabe, opanga ambiri amagwiritsabe ntchito ma valve achikhalidwe olowera njira imodzi omwe adapangidwira mtundu wakale wogulitsa.
Kupanga matumba otsekeredwanso ndi makina ochotsera utsi omwe ali mkati mwa makampani olembetsa kumathandiza makasitomala kusunga utsi watsopano akamatsegula mobwerezabwereza komanso kuwongolera mpweya wa CO2 wochokera ku matumba omwe amagwiritsidwa ntchito pang'ono.
Momwe Mungasankhire Valuvu Yoyenera Yopangira Khofi
Yambani podziwa nthawi kuyambira kuwotcha mpaka kulongedza. Yesani bwino—osati pamene mukufuna kutseka khofi, koma pamene mutsekadi pansi pa mikhalidwe yabwinobwino yopangira khofi.
Ngati kutseka kukufunika mkati mwa maola 6 kuchokera pamene kuwotcha, tchulani ma valve othamanga kwambiri (10 mm m'mimba mwake kapena kuposerapo) omwe ali ndi mphamvu ya 2 psi kapena kuposerapo. Ngati kutseka kukufunika mkati mwa maola 12-24, ma valve okhazikika a 8 mm m'mimba mwake adzakhala oyenera kugwiritsidwa ntchito nthawi zambiri. Ngati kutseka kukufunika kwa maola 48 kapena kuposerapo, ganizirani ngati mukufuna valavu ya mapaketi osakwana ma ounces 12.
Lumikizanani nafe kuti mudziwe zambiri
