——Nhungamiro yenzira dzekuchengetedza bhinzi yekofi
Mushure mekusarudza bhinzi yekofi, basa rinotevera nderekuchengetedza bhinzi dzekofi. Unoziva here kuti bhinzi yekofi ndiyo inofefetera mukati memaawa mashoma ekugochwa? Ndeipi kurongedza ndiyo yakanakisa kuchengetedza kutsva kwebhinzi yekofi? kofi bhinzi inogona kuchengetwa mufiriji? Zvadaro tichakuudza chakavanzika chekofi bhinzi packaginguye kuchengetedza.
Kofi Bean Packaging uye Kuchengetedza: Kofi ine Fresh Beans
Kufanana nekudya kwakawanda, kutsva kwacho, ndiko kunowedzera kwechokwadi. Izvo zvakafanana zvinoenda kune bhinzi yekofi, kutsva kwadzo, kunowedzera kunaka. Zvakaoma kutenga bhinzi dzekofi dzemhando yepamusoro, uye haudi kunwa kofi ine huturu hwakadzikiswa zvakanyanya nekuda kwekusachengeteka zvakanaka. Kofi bhinzi inonyatso nzwisisa kune yekunze nharaunda, uye yakanakisa kuravira nguva haisi refu. Nzira yekuchengetedza zvakanaka bhinzi yekofi inyaya yakakosha kune avo vanoteedzera yemhando yepamusoro kofi.
Kutanga, ngatitarisei maitiro ebhinzi yekofi. Mushure mekunge mafuta ebhinzi yekofi yakakangwa yakagochwa, pamusoro pacho pachava nekupenya kupenya (kunze kwebhinzi yekofi yakakangwa uye bhinzi yakakosha yakagezwa nemvura kubvisa caffeine), uye bhinzi icharamba ichiita mamwe maitiro uye kusunungurwa. carbon dioxide. . Benzi dzekofi itsva dzinoburitsa marita mashanu kusvika gumi nemaviri ecarbon dioxide pakirogiramu. Ichi chiitiko chekupedza simba ndechimwe chekiyi yekusiyanisa kana kofi iri nyowani.
Kuburikidza nemaitiro aya ekuchinja kunoramba kuripo, kofi inotanga kuva nani mushure memaawa makumi mana nemasere ekugocha. Zvinokurudzirwa kuti nguva yakanakisisa yekuravira yekofi ndeye 48 maawa mushure mekugocha, zvichida kwete kupfuura mavhiki maviri.
Zvinhu zvinokanganisa kutsva kwebhinzi yekofi
Kutenga bhinzi yekofi ichangobva kugochwa kamwe chete pamazuva matatu zviri pachena kuti hazvishande kuvanhu vemazuva ano vakabatikana. Nekuchengeta bhinzi dzekofi nenzira kwayo, unogona kudzivirira dambudziko rekutenga uye uchiri kunwa kofi inochengeta kunaka kwayo kwepakutanga.
Bhinzi yekofi yakakangwa inonyanya kutya zvinhu zvinotevera: okisijeni (mhepo), unyoro, chiedza, kupisa, uye hwema. Oxygen inokonzera kuti kofi tofu iende yakaipa uye iparare, hunyoro hunosuka mafuta anonhuwira pamusoro pekofi, uye zvimwe zvinhu zvinokanganisa maitiro mukati mebhinzi yekofi, uye pakupedzisira zvinokanganisa kunaka kwekofi.
Kubva pane izvi iwe unofanirwa kukwanisa kufungidzira kuti nzvimbo yakanakisisa yekuchengetedza bhinzi yekofi inzvimbo isina oxygen (mhepo), yakaoma, yakasviba uye isina kunhuwa. Uye pakati pavo, kuparadzanisa okisijeni ndiyo yakanyanya kuoma.
Vacuum packaging hazvirevi kutsva
Zvimwe unofunga kuti: “Chii chakaoma pakuchengeta mhepo?Vacuum packagingzvakanaka. Zvikasadaro, isa mugaba rekofi risina mhepo, uye oxygen haipinde. Vacuum kurongedza kana zvizereairtight packaginginogona kunge yakaoma zvikuru kune zvimwe zvinhu. Zvakanaka, asi isu tinofanirwa kukuudza kuti hapana package yakakodzera bhinzi dzekofi nyowani.
Sezvatakambotaura, bhinzi dzekofi dzicharamba dzichiburitsa kabhoni dhaikisaidhi yakawanda mushure mekugocha. Kana iyo bhinzi yekofi iri muvacuum package iri nyowani, bhegi rinofanira kuputika. Naizvozvo, tsika yakajairika yevagadziri ndeyekurega bhinzi yekofi yakakangwa imire kwenguva yakati rebei, vozoiisa muvacuum packaging mushure mekunge bhinzi dzisisina kupera. Nenzira iyi, haufanirwe kunetseka nezve kubuda, asi bhinzi hadzina kunhuhwirira kwakanyanya. Zvakanaka kushandisa vacuum packaging yehupfu hwekofi, asi isu tese tinoziva kuti poda yekofi pachayo haisi iyo nyowani yekofi.
Yakavharwa kurongedzazvakare haisi nzira yakanaka. Kurongedza kwakavharwa kunongodzivirira mweya kuti usapinda, uye mweya uri mukutanga kurongedza haugone kutiza. Kune 21% okisijeni mumhepo, iyo yakaenzana nekuvhara okisijeni nebhinzi yekofi pamwe chete uye haigone kuwana yakanakisa kuchengetedza maitiro.
Iyo Yakanakisa Chishandiso Chekuchengetedza Kofi: One-Way Vent Valve
Mhinduro chaiyo iri kuuya. Chishandiso chinogona kuita zvakanakisa kuchengetedza kutsva kwebhinzi dzekofi pamusika ivharuvhu yenzira imwe chete, iyo yakagadzirwa neFres-co Company muPennsylvania, USA muna 1980.
sei? Kuti uongorore fizikisi yakapfava yechikoro chesekondari pano, gasi rakareruka rinofamba nekukurumidza, saka munzvimbo ine chinobuda chimwe chete uye pasina gasi rinopinda, gasi rakareruka rinoita kutiza, uye gasi rinorema rinogara. Izvi ndizvo zvatinoudzwa neMutemo waGraham.
Fungidzira bhegi rakazara nebhinzi dzekofi itsva ine imwe nzvimbo yasara izere nemhepo ine 21% oksijeni uye 78% nitrogen. Carbon dioxide inorema kupfuura ose ari maviri magasi aya, uye pashure pokunge bhinzi dzekofi dzabudisa carbon dioxide, inosvina okisijeni nenitrogen. Panguva ino, kana pane imwe nzira yevhavhavhavha, gasi rinogona kubuda chete, asi kwete mukati, uye okisijeni iri mubhegi ichava shoma nekufamba kwenguva, izvo zvatinoda.
Iyo oksijeni shoma, zviri nani kofi
Oxygen ndiyo inokonzera kuparara kwebhinzi yekofi, inova imwe yenheyo dzinofanirwa kutariswa pakusarudza nekuongorora zvakasiyana siyana zvekuchengetedza bhinzi yekofi. Vamwe vanhu vanosarudza kupinza buri diki mubhegi rekofi, iro riri nani pane chisimbiso chakazara, asi huwandu uye kukurumidza kwekupukunyuka kweokisijeni kunogumira, uye gomba ipombi ine nzira mbiri, uye okisijeni kunze ichaita. mhanyawo mubhegi. Kuderedza mhepo yemukati mupakeji ndeyechokwadi zvakare sarudzo, asi chete-nzira imwe chete vent valve inogona kuderedza iyo oksijeni yemukati mubhegi rekofi.
Mukuwedzera, inofanira kuyeuchidzwa kuti kuvhara nevhavha yemhepo imwe chete inofanira kuiswa chisimbiso kuti ibudirire, kana zvisina kudaro okisijeni inogona kuramba ichipinda muhombodo. Usati waisa chisimbiso, unogona kusvina zvinyoronyoro kunze kwemhepo yakawanda sezvinobvira kuderedza nzvimbo yemhepo mubhegi uye huwandu hweokisijeni hunogona kusvika kubhinzi yekofi.
Maitiro ekuchengeta kofi bhinzi Q&A
Ehe, iyo imwe-nzira vent valve ingori kutanga kwekuchengetedza kofi bhinzi. Pazasi takanyora mimwe mibvunzo yaungave unayo, tichitarisira kukubatsira iwe kunakidzwa nekofi inofefesa mazuva ese.
●Ko kana ndikatenga bhinzi yekofi yakawandisa?
Zvinowanzokurudzirwa kuti nguva yakanakisisa yekuravira yebhinzi yekofi ivhiki mbiri, asi kana ukatenga anopfuura mavhiki maviri, nzira yakanakisisa ndeyokuishandisa mufiriji. Tinokurudzira kushandisa mabhegi efiriza anovharika (aine mweya mudiki sezvinobvira) uye nekuachengeta mumapakiti madiki, asingapfuure mavhiki maviri ega ega. Bvisa bhinzi yekofi awa imwe usati washandisa, uye mirira kuti ice itonhore kusvika kune tembiricha yekamuri isati yavhura. Iko kune kuderera kudiki pamusoro pebhinzi yekofi. Usakanganwa kuti hunyoro huchakanganisa zvakanyanya kunaka kwebhinzi yekofi. Usadzorere bhinzi dzekofi dzakatorwa mufiriji kuti udzivise hunyoro hunokanganisa kunaka kwekofi panguva yekunyunguduka uye nechando.
Nekuchengetedza kwakanaka, bhinzi dzekofi dzinogona kugara dzakatsva kwemavhiki maviri mufiriji. Inogona kusiiwa kusvika kumwedzi miviri, asi haina kukurudzirwa.
●Ko bhinzi yekofi inogona kuchengetwa mufiriji here?
Kofi bhinzi haigoni kuchengetwa mufiriji, mufiriji chete ndiwo unokwanisa kuzvichengeta zviri zvitsva. Chekutanga ndechekuti tembiricha haina kudzika zvakakwana, uye yechipiri ndeyekuti bhinzi dzekofi pachadzo dzine mhedzisiro yekubvisa kunhuhwirira, izvo zvinotora kunhuhwirira kwezvimwe zvekudya mufiriji mubhinzi, uye kofi yekupedzisira yakabikwa inogona kunge iine kunhuwa kwefiriji yako. Hapana bhokisi rekuchengetedza rinogona kuramba kunhuhwirira, uye kunyange nzvimbo dzekofi hadzina kukurudzirwa mufiriji yefiriji.
●Mazano pamusoro pekuchengetedzwa kwekofi yakabikwa
Nzira yakanakisisa yekuchengetedza kofi yepasi ndeyekubikira mukofi uye kuinwa, nokuti nguva yekuchengetedza yekofi yepasi iawa imwe chete. Kofi ichangoburwa uye yakabikwa inochengeta kunaka kwakanyanya.
Kana pasina chaizvo nzira, saka tinokurudzira kuchengeta kofi yepasi mumudziyo usina mhepo (porcelain yakanakisisa). Kofi yepasi inonyanya kubatwa nehunyoro uye inofanira kuchengetwa yakaoma, uye edza kusaisiya kweanopfuura mavhiki maviri.
●Ndeipi mitemo yakawanda yekuchengetedza bhinzi yekofi?
Tenga bhinzi itsva dzemhando yepamusoro, zvirongedze zvakasimba mumigaba ine rima ine mapopoma enzira imwe chete, woichengeta munzvimbo yakaoma, inotonhorera kure nechiedza chezuva nechitsinga. Maawa makumi mana nemasere mushure mekunge bhinzi yekofi yakagochwa, kunhuhwirira kunowedzera zvishoma nezvishoma, uye kofi inotonhorera inochengetwa pamhepo tembiricha kwemavhiki maviri.
●Sei kuchengeta bhinzi dzekofi kuine tsiye dzakawanda kudaro, kuita sekunge kunetsa
Zviri nyore, nekuti yakanaka yekofi yakakodzera dambudziko rako. Kofi chinwiwa chemazuva ese, asi kune hupfumi hweruzivo rwekudzidza. Ichi ndicho chikamu chinonakidza chekofi. Zvinzwe nemoyo wako uye kuravidza iyo yakakwana uye yakachena inonaka yekofi pamwe chete.
