Qhov ntom ntawm cov pob kws zom ua ke ua lub cim qhia ncaj qha ntawm cov suab thaj uas tuaj yeem ferment tau. Thaum lub sijhawm ua cov txheej txheem distillation cawv, qhov ntom ntawm cov zom ua ke ntau dua sib raug rau qhov muaj suab thaj ntau dua, thiab yog li ntawd qhov theoretical yield ntawm ethanol ntau dua yog tias kev hloov pauv tiav.
Qhov ceev ntawm cov pob kws zom yog qhov tseem ceeb hauv cov txheej txheem fermentation ntawm lub chaw ua dej cawv, uas cuam tshuam rau kev ua kom zoo dua ntawm txhua theem. Qhov ceev yog hais txog qhov hnyav ntawm cov zom ib chav ntim, thiab hauv cov ntsiab lus ntawm cov zom pob kws, yog txiav txim siab los ntawm qhov concentration ntawm cov khoom yaj thiab cov khoom dais - feem ntau yog cov suab thaj tsis tau fermented, starches, thiab cov khoom me me los ntawm kev zom.
Pob kws Mash hauv Kev Tsim Dej Cawv
Cov pob kws zom yog cov khoom sib xyaw ua ke uas siv los tsim cov cawv uas tau lim dej zoo li bourbon thiab pob kws whiskey. Hauv nws lub hauv paus, cov cawv zom pob kws thiab cov cawv zom pob kws yog cov cawv uas tsim los ntawm cov khoom sib xyaw uas pob kws yog cov nplej tseem ceeb - raws li txoj cai lij choj hauv Tebchaws Meskas, tsawg kawg 80% ntawm daim nqi zom rau cov pob kws whiskey yuav tsum yog pob kws. Cov txheej txheem kev cai lij choj no ua kom ntseeg tau tias cov cawv tshwj xeeb thiab tso cov pob kws zom rau hauv nruab nrab ntawm nws tus kheej thiab cov txheej txheem tsim khoom.
Kev Txheeb Xyuas Txog Cov Txheej Txheem Tsim Dej Cawv
Kev tsim cawv pib nrog cov noob pob kws nyoos, uas raug tshuab zom siv cov tshuab dov lossis rauj zeb kom nce thaj chaw saum npoo. Cov pob kws hauv av ces muab sib xyaw nrog dej hauv cov txheej txheem hu ua mashing. Cov mash raug cua sov thiab kho nrog cov enzymes, feem ntau yog alpha-amylase thiab glucoamylase, los hloov cov hmoov pob kws ua suab thaj fermentable - qhov no yog cov txheej txheem saccharification hmoov pob kws. Thaum saccharified, poov xab raug qhia kom ferment cov suab thaj no rau hauv cawv. Cov mash fermented, lossis "npias," ces distilled - feem ntau hauv kem lossis lauj kaub stills - kom sib cais thiab concentrate cov ethanol. Qee cov khoom, xws li bourbon, dhau los ua aging tom qab hauv cov thoob, thaum cov whiskey pob kws yuav pom kev laus tsawg lossis tsis muaj.

Kev ntsuas qhov ceev ntawm cov pob kws mash hauv lub sijhawm tiag tiag yog qhov tseem ceeb rau kev ua kom zoo dua ntawm cov enzyme dosage hauv cov chaw ua dej cawv. Kev nyeem cov density kom raug tso cai rau cov neeg ua haujlwm kho kom zoo dua cov enzymes, xws li amylase lossis cellulase, siv los rhuav cov starches thaum lub sijhawm saccharification. Piv txwv li, kev tsom mus rau cellulase dosage ntawm 50 FPU / L tau pom tias txo cov viscosity ntawm mash los ntawm ntau dua 40%, nce ethanol yield los ntawm 12%, thiab txo cov suab thaj seem los ntawm ntau dua ib nrab. Yog tsis muaj cov ntaub ntawv mash density tseeb, kev ntxiv enzyme yuav muaj kev pheej hmoo siab dhau - pov tseg cov peev txheej - lossis qis dhau, ua rau starch tsis lwj thiab txwv tsis pub hloov mus ua cawv. Kev ntsuas qhov ceev hauv kab txhais tau tias cov koob tshuaj teb tam sim ntawd rau cov xwm txheej mash tiag tiag, tshwj xeeb tshaj yog thaum cov khoom siv raw zoo sib txawv, ua kom zoo tshaj plaws ob qho tib si kev lag luam thiab kev ua tau zoo.
Vim li cas kev ntsuas qhov ntom ntom inline thiaj li tseem ceeb hauv cov txheej txheem fermentation ntawm distillery?
Kev ntsuas qhov ceev hauv kab muab cov distillators nrog kev taug qab txhua lub sijhawm, tsis siv neeg ntawm cov xwm txheej mash thoob plaws hauv cov txheej txheem fermentation. Cov ntaub ntawv txuas ntxiv no txhawb nqa kev kuaj pom thaum ntxov ntawm qhov tsis zoo - xws li kev hloov pauv hmoov txhuv nplej siab tsis tiav lossis kev ntxhov siab ntawm cov poov xab - tso cai rau kev kho kom sai. Cov kab ke hauv kab, suav nrog Coriolis mass flowmeters thiab vibration-type liquid density meters, xa cov ntawv nyeem nrog kev nkag siab siab thiab raug. Lawv siv txhim kho cov khoom sib xws los ntawm ib pawg mus rau ib pawg thiab ua rau muaj kev hloov kho cov tshuaj enzyme tam sim ntawd, yog li ua kom cov txheej txheem fermentation distillery zoo dua thiab txo cov neeg ua haujlwm tes. Kev ua raws li txoj cai kuj tau txhawb nqa los ntawm kev saib xyuas hauv kab, vim nws ua kom muaj kev sib xyaw ntawm cov cawv raug cai thiab cov khoom zoo sib xws yam tsis muaj kev cuam tshuam tes.
Puas muaj qhov sib txawv ntawm qhov ceev ntawm cov kua txiv hmab txiv ntoo uas muaj pob kws uas muaj cawv txiv hmab puas cuam tshuam rau tus cwj pwm kawg ntawm cov cawv?
Yog. Kev hloov pauv ntawm qhov ceev ntawm pob kws mash ncaj qha cuam tshuam rau kev ua haujlwm ntawm fermentation, kev siv substrate los ntawm cov poov xab, thiab cov qauv ntawm cov khoom lag luam metabolic. Qhov ceev ntau dua tuaj yeem ua rau cov cawv kawg nce ntxiv, tab sis kuj hloov qhov sib npaug ntawm cov tshuaj volatile tsim tawm - xws li cov cawv ntau dua, esters, thiab aldehydes - cuam tshuam rau qhov saj, aroma, thiab kev ntxhib los mos. Piv txwv li, kev tshawb fawb siv GC-MS thiab sensory panels tau txuas cov mash densities siab dua rau cov txiv hmab txiv ntoo thiab paj ntxiv, thaum qhov ceev ntau dhau tuaj yeem ua rau cov qab zib seem lossis cov seem tsis xav tau. Ntawm qhov tod tes, qhov ceev tsawg dhau yuav ua rau cov cawv nyias nyias, tsis muaj zog nrog tus cwj pwm tsis zoo. Kev tswj hwm qhov ceev ceev pab cov neeg distillators ua tiav qhov saj sib xws, tsom mus rau thiab du hauv kev tsim cov cawv mash pob kws.
Kev saib xyuas qhov ceev ntawm cov hmoov nplej ua rau cov txheej txheem ua haujlwm tau zoo dua li cov txheej txheem kuaj ib txwm muaj li cas?
Kev soj ntsuam qhov ceev ntawm cov cawv mash uas siv lub sijhawm tiag tiag, inline, zoo dua li cov txheej txheem kuaj tes ib txwm muaj hauv ntau txoj hauv kev tseem ceeb. Cov thev naus laus zis inline muab cov lus teb tam sim ntawd thiab ua kom cov ntaub ntawv sau tau yooj yim, tshem tawm ob qho kev ncua thiab kev pheej hmoo ntawm kev ua yuam kev ntawm tib neeg uas cuam tshuam nrog kev kuaj xyuas qhov ceev ntawm tes tsis tu ncua. Qhov no ua kom cov txheej txheem kho sai dua - txawm tias yog kev ntsuas enzyme lossis kho cov txheej txheem fermentation - ua rau cov kauj ruam ua haujlwm distillation cawv sib xws dua thiab ua haujlwm tau zoo dua. Cov cuab yeej ntsuas qhov ceev niaj hnub no sau cov qauv sib xws, tso cai rau kev kuaj pom qhov yuam kev tam sim ntawd thiab txo qhov yuav muaj cov khoom tsis zoo. Cov ntaub ntawv kev lag luam lees paub tias kev soj ntsuam tas mus li txo cov kev xav tau ntawm cov neeg ua haujlwm, ua kom muaj kev tswj hwm cov txheej txheem nruj dua, thiab txhawb nqa ob qho tib si cov cawv thiab cov khoom sib xws, tshwj xeeb tshaj yog ntawm qhov ntsuas kev lag luam.
