Sindikudziwa ngati mwaonapo, kupatulapo mitundu ina ikuluikulu ya unyolo, nthawi zambiri sitimawona makapu osefera a trapezoidal m'masitolo a khofi. Poyerekeza ndi makapu osefera a trapezoidal, kuchuluka kwa makapu osefera a conical, flat bottom/keke ndi kwakukulu kwambiri. Anzanu ambiri anayamba kuda nkhawa, nchifukwa chiyani anthu ochepa amagwiritsa ntchito makapu osefera a trapezoidal? Kodi ndi chifukwa chakuti khofi yomwe imapanga si yokoma?
Ayi ndithu, makapu osefera a trapezoidal alinso ndi ubwino wochotsa makapu osefera a trapezoidal! Mofanana ndi makapu osefera okhala ndi mawonekedwe ofanana, dzina lakuti chikho chosefera cha trapezoidal limachokera ku kapangidwe kake kapadera ka mtundu uwu wa chikho chosefera. Ndi kapangidwe ka trapezoidal kokhala ndi pamwamba ndi pansi pang'ono, motero amatchedwa "chikho chosefera cha trapezoidal". Kuphatikiza apo, chifukwa cha mawonekedwe a pepala losefera lomwe limagwiritsidwa ntchito limodzi ndi chikho chosefera cha trapezoidal chofanana ndi fan, chikho choseferachi chimadziwikanso kuti "chikho chosefera chooneka ngati fan".
Chikho choyamba chosefera chomwe chinabadwa padziko lonse lapansi chinagwiritsa ntchito kapangidwe ka trapezoidal. Mu 1908, Melitta wochokera ku Germany adayambitsa chikho choyamba chosefera khofi padziko lonse lapansi. Monga momwe Qianjie adayambitsa, ndi kapangidwe ka trapezoidal kozungulira komwe kali ndi nthiti zingapo zomwe zimapangidwa mkati mwa khoma la chikho kuti zitulutse utsi, ndi dzenje laling'ono pansi kuti ligwiritsidwe ntchito ndi pepala losefera looneka ngati fan.
Komabe, chifukwa cha kuchuluka ndi kukula kwa mabowo otulukira madzi, liwiro lake lotulutsa madzi ndi lochepa kwambiri. Chifukwa chake mu 1958, khofi wopangidwa ndi manja atatchuka ku Japan, Kalita adayambitsa "mtundu wabwino". "Kusintha" kwa chikho chosefera ichi ndikukweza kapangidwe ka dzenje limodzi loyambirira kukhala mabowo atatu, zomwe zimafulumizitsa kwambiri liwiro la madzi ndikuwonjezera mphamvu yophikira. Chifukwa cha izi, chikho chosefera ichi chakhala chodziwika bwino cha makapu osefera a trapezoidal. Chifukwa chake, kenako, tidzagwiritsa ntchito chikho chosefera ichi kuti tidziwitse ubwino wa chikho chosefera cha trapezoidal pakupangira mowa.
Chikho cha fyuluta chili ndi mapangidwe atatu ofunikira omwe amakhudza kutulutsa, omwe ndi mawonekedwe awo, nthiti, ndi dzenje la pansi. Nthiti za chikho cha fyuluta cha Kalita101 trapezoidal zimapangidwa molunjika, ndipo ntchito yake yayikulu ndi utsi. Ndipo kapangidwe kake kakunja ndi kotakata pamwamba komanso kopapatiza pansi, kotero ufa wa khofi umapanga bedi lokhuthala la ufa mu chikho cha fyuluta. Bedi lokhuthala la ufa limatha kukulitsa kusiyana kwa kutulutsa panthawi yopangira, ndipo ufa wa khofi pamwamba pake udzalandira kutulutsa kochuluka kuposa ufa wa khofi wapansi. Izi zimalola kuchuluka kosiyanasiyana kwa zinthu zokometsera kusungunuka kuchokera ku ufa wosiyanasiyana wa khofi, zomwe zimapangitsa khofi wopangidwa kukhala wosalala kwambiri.
Koma chifukwa kapangidwe ka pansi pa chikho chosefera cha trapezoidal ndi mzere osati mfundo, bedi la ufa lomwe limapangidwa silidzakhala lokhuthala ngati chikho chosefera cha conical, ndipo kusiyana kwa kuchotsa kudzakhala kochepa.
Ngakhale kuti pali mabowo atatu otulutsira madzi pansi pa chikho cha Kalita 101 trapezoidal filter, kutsegula kwawo si kwakukulu, kotero liwiro la madzi silidzakhala lachangu ngati makapu ena osefera. Ndipo izi zilola kuti khofi alowe kwambiri panthawi yopangira mowa, zomwe zimapangitsa kuti khofiyo ichotsedwe bwino. Khofi wopangidwayo adzakhala ndi kukoma koyenera komanso kapangidwe kolimba.
Kuona ndi kukhulupirira, choncho tiyeni tiyerekezere V60 ndi kapu yosefera ya trapezoidal kuti tiwone kusiyana kwa khofi yomwe amapanga.Magawo ochotsera ndi awa:
Kugwiritsa ntchito ufa: 15g
Chiŵerengero cha madzi a ufa: 1:15
Mlingo wopera: Ek43 scale 10, 75% sefa yozembetsa 20, kupeta shuga wabwino
Kutentha kwa madzi otentha: 92 ° C
Njira yowiritsa: magawo atatu (30+120+75)
Chifukwa cha kusiyana kwa kukula kwa ma pore, pali kusiyana pang'ono pa nthawi yotulutsa pakati pa ziwirizi. Nthawi yopangira nyemba za khofi ndi V60 ndi mphindi ziwiri, pomwe nthawi yogwiritsira ntchito chikho chosefera cha trapezoidal ndi mphindi ziwiri ndi masekondi 20. Ponena za kukoma, Huakui yopangidwa ndi V60 ili ndi mphamvu zambiri zogawika! Maluwa a lalanje, citrus, sitiroberi, ndi zipatso, zokhala ndi kukoma kodziwika bwino, kukoma kokoma ndi kowawasa, kapangidwe kosalala, komanso kukoma kwa tiyi wa oolong; Huakui yopangidwa pogwiritsa ntchito chikho chosefera cha trapezoidal mwina singakhale ndi kukoma kosiyana komanso kofanana ndi V60, koma kukoma kwake kudzakhala koyenera, kapangidwe kake kadzakhala kolimba kwambiri, ndipo kukoma kwa pambuyo pake kudzakhala kwakutali.
Zikuoneka kuti pansi pa magawo ndi njira zomwezo, khofi wopangidwa ndi awiriwa ali ndi mitundu yosiyana kwambiri! Palibe kusiyana pakati pa chabwino ndi choipa, zimatengera zomwe munthu aliyense amakonda. Mabwenzi omwe amakonda khofi wokhala ndi kukoma kodziwika bwino komanso kukoma kopepuka amatha kusankha V60 popanga mowa, pomwe anzawo omwe amakonda khofi wokhala ndi kukoma koyenera komanso kapangidwe kolimba amatha kusankha makapu oyesera a trapezoidal.
Pakadali pano, tiyeni tibwerere ku mutu wakuti 'N’chifukwa chiyani makapu oyeretsera a trapezoidal ndi osowa kwambiri?'! Mwachidule, zikutanthauza kusiya chilengedwe. Kodi zimenezi zikutanthauza chiyani? Pamene chikho choyeretsera cha trapezoidal chinapangidwa kale, khofi wokazinga kwambiri ndiye anali wotchuka kwambiri, kotero chikho choyeretsera chinapangidwa makamaka mozungulira momwe khofi wophikidwayo angapangire kukoma kokoma, ndipo kukoma kwa khofi wophikidwayo kukanakhala kofooka pang'ono. Koma pambuyo pake, khofi woyeretsera anasintha kuchoka pa kuya kupita pa kuya, ndipo anayamba kuyang'ana kwambiri kukoma. Chifukwa chake, kufunikira kwa anthu ambiri makapu oyeretsera kunasintha, ndipo anayamba kufunikira makapu oyeretsera omwe angawonetse bwino ndikuwonjezera kukoma. V60 ndi yodziwika bwino, kotero idalandira yankho labwino ikangoyambitsidwa! Kutchuka kwakukulu kwa V60 sikunangodzipangira mbiri yake yokha, komanso kunavumbula kwambiri msika wa makapu oyeretsera a conical. Chifukwa chake kuyambira pamenepo, opanga zida zazikulu za khofi ayamba kufufuza ndikupanga makapu oyeretsera a conical, ndikuyambitsa makapu atsopano oyeretsera a conical chaka chilichonse.
Kumbali ina, mawonekedwe ena a makapu osefera, kuphatikizapo makapu osefera a trapezoidal, akuchepa kwambiri chifukwa opanga ochepa ayesetsa kuwagwiritsa ntchito. Mwina ali ndi chidwi ndi kapangidwe ka makapu osefera okhala ndi mawonekedwe ozungulira, kapena akufufuza makapu osefera okhala ndi mawonekedwe apadera komanso ovuta. Kuchuluka kwa zosintha kwachepa, ndipo kuchuluka kwa makapu osefera kwachepa, kotero mwachibadwa, kukuchepa kwambiri. Komabe, izi sizikutanthauza kuti makapu osefera okhala ndi mawonekedwe a trapezoidal kapena ena ndi osavuta kugwiritsa ntchito, akadali ndi mawonekedwe awoawo opangira mowa. Mwachitsanzo, chikho chosefera cha trapezoidal sichifuna luso lapamwamba la madzi kuchokera kwa baristas monga chikho chosefera chokhala ndi mawonekedwe ozungulira chifukwa bedi la ufa silolimba kwambiri, nthiti sizimawonekera kwambiri, ndipo khofi amachotsedwa ponyowa kwa nthawi yayitali.
Ngakhale oyamba kumene amatha kupanga kapu ya khofi wokoma mosavuta popanda luso lawo, bola ngati akhazikitsa miyezo monga kuchuluka kwa ufa, kupukutira, kutentha kwa madzi, ndi chiŵerengero. Chifukwa chake makapu osefera a trapezoidal nthawi zambiri amakondedwa ndi makampani akuluakulu a unyolo, chifukwa amatha kuchepetsa kusiyana pakati pa oyambira ndi akatswiri odziwa bwino ntchito, ndikupatsa makasitomala kapu ya khofi yokhazikika komanso yokoma.
