Ngo-1938, iNestle yasebenzisa indlela ethuthukisiwe yokomisa ikhofi ukuze ikhiqizwe ngokushesha, okuvumela ukuthi i-powder yekhofi esheshayo incibilike ngokushesha emanzini ashisayo. Ngaphezu kwalokho, ivolumu encane nosayizi kwenza kube lula ukuyigcina. Ngakho-ke ithuthuke ngokushesha emakethe enkulu. Njengamanje izinhlobo zekhofi esheshayo ezidumile zifaka phakathi iNestle, iMaxwell, i-UCC, njll.
Inqubo yokukhiqiza ikhofi esheshayo
Ikhofi esheshayo iyisiphuzo esiqinile sekhofi esicutshungulwa ngokuthosa ubhontshisi wekhofi nokuwuchoboza, ukukhishwa kwezinto ezincibilikayo ngamanzi, bese womiswa ngomoya oshisayo noma ukomiswa ngeqhwa. Kulula ukuncibilikiswa emanzini bese ubuyela ekhofini eliwuketshezi elinokunambitheka nokunambitheka kwasekuqaleni. Inqubo yokukhiqiza imi kanje: ukuhlolwa kobhontshisi wekhofi, ukususwa kokungcola, ukuthosa, ukugaya, ukukhipha, ukuhlushwa, ukomiswa, ukupakisha.
II. Amaphuzu Ayinhloko Enqubo Yokukhiqiza Ikhofi Ngokushesha
(I) Ukwelashwa Kwangaphambi Kokuba Ubhontshisi Wekhofi Oluhlaza
Okokuqala, izinto zokusetshenziswa kufanele zikhethwe ngokucophelela. Ubhontshisi wekhofi omusha ukhanya, uyindilinga futhi ulingana ngobukhulu, ngaphandle kobhontshisi okhuntile, obilisiwe, omnyama, odliwe yizibungu, ophukile kakhulu kanye nowezinye eziphansi, kanye nokungcola okuhlukahlukene okufana namagobolondo embewu, amabhlogo enhlabathi, amabhlogo ezinkuni, amatshe, kanye nezinsimbi. Ukuze kuqinisekiswe ikhwalithi, ukuhlukaniswa kungenziwa ngezikrini ezidlidlizayo, ukucindezela komoya noma ukuhanjiswa kwe-vacuum.
(II) Ukuthosa
Ukuthosa kuyinqubo enqumayo yokwakheka kokunambitheka kanye nekhwalithi yekhofi esheshayo. Izinqubo zezentengiselwano zobhontshisi bekhofi zisebenzisa i-half hot-air direct fire roaster noma i-hot air roaster enamakamelo okuthosa ngesimo sesigubhu esijikelezayo ngokuvamile. Izinga lokushisa lokuthosa kanye nesikhathi sokuthosa yizinto ezibalulekile ezibalulekile.
Ubude besikhathi sokosa buyahlukahluka hhayi nje ngenxa yohlobo lwekhofi kanye nohlobo lwayo, kodwa futhi kuya ngezinga lokosa elidingekayo kumkhiqizo wokugcina. Isikhathi esifushane sokosa sibonisa ukuthi ubhontshisi wekhofi uthambile futhi une-asidi enamandla, ukubaba okubuthakathaka kanye nokukhishwa okulula ngemva kokugaya. Ngokuphambene nalokho, isikhathi eside sokosa sibonisa ukuthi ubhontshisi wekhofi uqinile futhi une-asidi ebuthakathaka, ukubaba okunamandla kanye nokusebenza kahle kokukhipha ukuze uthole impuphu ecolekileyo eningi.
Ukungagayi ngokwanele kuzoholela ephunga elibi, umbala ongemuhle womkhiqizo oqediwe kanye nesilinganiso esiphansi sokukhipha; ukugayiwa ngokweqile kuzoholela ekunisweni kakhulu kwamafutha, okuzophazamisa ukukhishwa futhi kuthinte ukusebenza kokomisa ngokufutha. Ngakho-ke, izimo ezinhle zokugaya kumele zinqunywe umbala womkhiqizo, iphunga, isivuno, ukusebenza kahle kwezomnotho kanye nezimo zokuklama imishini yokukhiqiza.
Uma ubhontshisi wekhofi ufika ezingeni elidingekayo lokuthosa, cisha umlilo, yeka ukufudumeza, bese upholisa ubhontshisi wekhofi ngokushesha. Ngoba noma ngabe ukuthosa kuyekile, ukushisa okungaphakathi kobhontshisi wekhofi kuzoqhubeka nokuthosa isikhathi esithile, ngakho-ke ngemva kokuba ubhontshisi wekhofi uthululwe egumbini lokuthosa idrama, ifeni yokukhipha ugesi kufanele ivulwe ukuze ipholise ukuze kuvinjwe izinga lokushisa lingakhuphuki. Embonini, inani elithile lamanzi abandayo lifuthwa ekamelweni lokuthosa ukuze liphole, bese ubhontshisi wekhofi othosiwe ukhishwa ekamelweni lokuthosa ukuze uphole.
(III) Isitoreji Esinganyakazi
Kungcono ukugcina ubhontshisi wekhofi othosiwe usuku olulodwa ukuze uvumele i-carbon dioxide kanye namanye amagesi ukuthi aqhume futhi akhululeke, kuyilapho futhi umunca ngokuphelele umswakama emoyeni ukuze athambise ubhontshisi, okulungele ukukhishwa. Usayizi wosayizi wezinhlayiya zokugaya uhlobene nemishini yokukhipha esetshenziswayo. Izinhlayiya ezincane zilungele ukukhishwa kahle kakhulu kodwa zivimbela ukuhlunga okulandelayo kuyilapho izinhlayiya eziqinile zinzima ukukhishwa kodwa kulula ukuhlunga. Ngokuvamile, ububanzi obujwayelekile bezinhlayiya zekhofi ezigayiwe bungaba ngu-1.5 mm.
(IV) Ukukhipha
Ukukhipha ikhofi kuyingxenye eyinkimbinkimbi kakhulu yenqubo yokukhiqiza ikhofi esheshayo. Imishini evame ukusetshenziswa ekukhipheni ibizwa ngokuthi i-extractor, equkethe amathangi okukhipha angu-6 kuya kwangu-8 axhunywe ngamapayipi futhi angakhiwa ngokushintshana abe yiyunithi yokusebenza.
(V) Ukuhlukaniswa Okuqinile Koketshezi
Uketshezi lwekhofi olukhishwe luzoba nezinto eziningi eziqinile ezisele. Lokhu kudinga ukuhlukaniswa koketshezi lwekhofi ngaphambi kokuba luthuthelwe enkambisweni elandelayo. Isihlukanisi sebhabhathane singafinyelela umphumela wokuhlukanisa odingekayo ngokujwayelekile.
(VI) Ukugxila
Ukugxila kuhlukaniswe ngokugxila kwe-vacuum, ukugxila kwe-centrifugal kanye nokugxila okuqandisiwe ngokujwayelekile. Ukuze kuthuthukiswe ukusebenza kahle kokomisa, kuncishiswe ukutshalwa kwezimali kwemishini kanye nokusetshenziswa kwamandla, ukugxila okuqinile kuyancishiswa kuze kufinyelele ngaphezu kuka-35%. Ukugxila kwe-vacuum kwehlisa izinga lokubila kwamanzi libe cishe ama-degrees angu-60 ekucindezelweni kwe-vacuum ngaphezu kuka-0.08Mpa. Ukuze uketshezi luqine ngokushesha. I-inline ikhofifei-e sli-urry i-concei-ntrationimithakusiza ukusetshenziswa kokugcina ngaphandle kokunqunywa kokuhlushwa okuphindaphindiwe nokukhathazayo ngokuqapha kwayo okunembile ngesikhathi sangempela. Ukuhlushwa kokuhlushwa ngokuvamile akudluli ku-60% (i-refractometer). Njengoba izinga lokushisa loketshezi oluqoqiwe oluphuma embhoshongweni wokuhwamuka liphakeme kunezinga lokushisa legumbi, kumele lipholiswe ngaphambi kokuthunyelwa ethangini lokugcina ukuze kuncishiswe ukulahleka.
(VII) Ukomisa ngesifutho
Uketshezi olugxilile luthuthwa ngqo phezulu kombhoshongo wokomisa ngokufutha ngepompo yokucindezela, lufuthwe ngesibhamu sokufutha ngokucindezela, bese lomiswa lube yimpuphu ngaphansi kokushisa nomoya ogeleza cishe ku-250°C. Ubuchwepheshe bokomisa nge-vacuum noma bokomisa ngokufutha bungasetshenziswa futhi ekomiseni. Ubuchwepheshe bokomisa ngokufutha buwukuqandisa i-coffee concentrate ekushiseni okuphansi, bese amanzi akuyo eqandisiwe abe yizinhlayiya ze-ice crystal ezincane, bese kushiswa futhi kufakwe ngaphansi kwezimo eziphezulu ze-vacuum ukuze kufezwe injongo yokomisa ngezinga lokushisa eliphansi. Ngemva kokuba i-concentrate isicutshunguliwe, ukwelashwa okwengeziwe okudingekayo kungenziwa ku-concentrate, futhi ingathuthukiswa ibe yisiphuzo esiwuketshezi.
Chofoza lapha ukuze uthole okwengeziweizixazululo zokuqapha ukuhlushwa okuqondileNoma ungaxhumanaI-Lonnmeterngqo nezidingo zakho ezithile.
