Nyob rau hauv cov hnub tsis ntev los no, ib co tshiab brewmaster nug peb yuav ua li cas brew npias los yog yuav ua li cas pib brewing, ntawm no, peb tham txog yuav ua li cas pib brewing.
Txawm hais tias nws yog npias brewing nees nkaum liters los yog ob txhiab liters ntawm npias, yeej ib txwm muaj ib txoj kev.
Cov kauj ruam rau npias brewing raws li hauv qab no:
1. Sib tsoo, malt milling
Lub tshuab cov menyuam nias lub sprouted barley los yog lwm yam khau rau hauv daim.
2. Brewhouse (Mashing kauj ruam)
Lub malt hu ua mash yog rhuab nrog dej li ib teev.Thaum nws nce mus txog 64-67 ℃, cov enzyme hauv pob yuav pib hloov cov hmoov txhuv nplej siab thiab polysaccharide rau hauv monosaccharides.Tus brewmaster yuav tsum txuas ntxiv do cov buds los ntawm lub tshuab los ntawm tes.
3. Lim (Lautering tank)
Tom qab lub bud yog precipitated, lub wort yog lim tawm, thiab ces cov nplej crust ( residue ) yog ntxuav nrog dej kub kom yaj cov qab zib ntxiv kom ntau li ntau tau.Thaum kawg ntawm cov kauj ruam no, cov nplej dregs yuav raug coj mus ua txiv neej chiv los yog xa mus rau pasture rau pub.
4. Boiling
Hloov cov wort mus rau lwm lub tank ua noj thiab ua kom sov li ib teev kom boil nws.Lub winemaker yuav ntxiv hops rau lub sij hawm no ntxiv iab thiab aroma.
5. Cua txias
Txhawm rau kom tsis txhob kis tus kab mob los yog lwm yam kab mob hauv lub wort, nws yog ib qho tsim nyog yuav tsum tau ceev kom txias kom qis dua 25 ℃.
NotedL Ntawm no nws muaj feem xyuam nrog peb brewing system, peb xav muab koj cov kev daws teeb meem zoo brewery:
1.Rau cov txheej txheem brewing, peb lub tsev brewhouse tuaj yeem brew ntau hom npias los ntawm 8 txog 14 plato wort kom tau raws li cov txheej txheem sib txawv.Nyob rau tib lub sijhawm, Peb cov khoom siv brewing tuaj yeem ua tiav kev tswj hwm ntawm cov kav dej thiab cov li qub kom ntau li ntau tau kom txo qis kev ua haujlwm ntawm brewmaster thiab txhim kho brewing efficiency.
2.Peb xav txog kev nyab xeeb ntau dua nyob rau hauv brewing tank, ib yam li peb lub taub hau ntawm brew tanks tag nrho yog cais los tiv thaiv qhov kub hnyiab vim nws yog kub thaum boiling.Tsis tas li ntawd hais txog qhov siab ntawm railing thiab qhov dav ntawm cov ntaiv yog tag nrho raws li cov cai hauv Tebchaws Europe lossis Asmeskas.
3. Cov ntsiab lus ntawm cov khoom siv, ib yam li cov cua kub ceev hauv lub tank boiling, peb tuaj yeem ua 1degree ib min raws li peb ntxiv cov cua sov coil ntawm lub tsho kom cov cua kub kom sib npaug thiab kev kub ceev.Tej zaum lwm tus neeg muag khoom tuaj yeem qhia koj tias lawv tseem tuaj yeem ua tau li ntawd, tab sis lawv tsis paub qhov cua sov ceev tiag tiag vim peb tau sim peb cov cuab yeej thiab tau txais cov ntaub ntawv meej.Hais txog cov khoom siv ntxiv, koj tuaj yeem pom cov ntaub ntawv txuas mus saib peb cov qauv tsim.
4.High theem brewery accessories kom phim peb cov brewing system, ib yam li lub cev muaj zog yog ABB, lub twj tso kua mis yog LYSF (Alfa Laval Tuam Tshoj Hoobkas), lub wort txias yog Nanhua (Sab saum toj theem nyob rau hauv cua sov exchnager), ntawm no peb yuav tsum tau saib cov cua sov kev ua tau zoo ntawm cov dej kub rov ua dua tshiab.Qhov kub ntawm Nanhua exch tuaj yeem ncav cuag 60-65degree tom qab txias lub wort thiab rov ua dua rau lub tank dej kub, tsuas yog koj ua kom sov me ntsis rau lub sijhawm tom ntej thiab txuag koj lub zog thiab sijhawm.Tab sis yog tias qhov ib txwm muaj, cov dej kub rov ua dua tsuas yog txog 30-40degree, uas txhais tau tias koj yuav ua kom sov nws ntev dua, qhov ntawd yog qhov pov tseg hauv lub sijhawm ntev brewing.Yog li, tag nrho cov khoom siv qib siab no yuav ua kom peb lub cev ua haujlwm zoo thiab txo tus nqi qis.
6. Fermentation
Nws tau lees paub tias wort yog khaws cia ntawm qhov ntsuas kub thiab tom qab ntawd muab tso rau hauv cov poov xab, uas yuav decompose cov monosaccharide thiab tsim cawv, carbon dioxide thiab esters (aroma molecules).Tom qab ib lub sij hawm ntawm fermentation, qhov tsw ntawm npias tuaj yeem paub tab.
7. Txias-soaked hops
Qee cov tshuaj tsw qab ntxiag heev hauv hops raug rhuav tshem los ntawm qhov kub thiab txias thaum lub sij hawm fermentation txheej txheem.Txhawm rau kom tshem tawm cov ntxhiab tsw zoo tshaj plaws, tus brewmaster yuav rov qab cov hops tom qab cov txheej txheem fermentation thiab lub raj mis npias hauv ob peb lub lis piam.
8. Kev ntsuas thiab ntsuas
Tus brewmaster yuav npaj qhov kev sim tom qab npias fermenting los yog cia tiav, ces txiav txim siab dab tsi yog kauj ruam tom ntej, kom txias los yog sau.
9.Filling thiab labeling
