Rectified ethyl cawv. Ethyl cawv - siv. ethyl cawv

Nws yog tsis muaj daim card uas raws li lub ntsiab raw khoom rau zus tau tej cov dej haus yog rectified ethyl cawv. Nws nemaloznachimy khoom nyob rau hauv cov cheeb tsam no. Yog xav paub ntxiv kom meej hauv qab no.

Hauj lwm ntawm cov khoom siv

Ethyl cawv rectified yog ib tug tsis muaj kob pob tshab kua, uas muaj tsis muaj tsw thiab aftertaste. Cov kev hnyav ntawm cov khoom nyob rau hauv 20 ° C sib npaug zos rau 0,78927 g / cm3. Ethanol, los yog ethyl cawv, twb xub tsim nyob rau hauv 1855 los ntawm ethylene. Qhov no cov ntaub ntawv uas yog ib tug flammable kua. Thaum nws yog tsim los ntawm combustion ntawm dej thiab carbon dioxide. cawv vapors muaj teeb meem rau kev noj qab nyob. Qhov siab tshaj plaws pub concentration hauv cov huab cua yog pom tias yuav tsum yog 1 mg / l. Nws khov kub yog -117 ° C thiab cov kub point: +78,2 ° C.

Ethanol - ib lub mis

Nws yog ib qho tseem ceeb kom paub. Cov kev tshuaj mis ntawm ethanol: C ₂ H ₅ OH. Nws qhia nyob tus yeees ntawm cov khoom thiab tau raug tsim muaj tau nyob rau hauv 1807. Tab sis tsuas yog tom qab nws ua tau zoo nyob rau hauv synthesizing ethyl cawv yam ntxwv mis twb muab tau. Nws yog sau raws li nram no: CH ₃ CH ₂ OH.

Ethanol yog ib tug nyeem cawv thiab, txij li thaum nws muaj tsuas yog ib OH pab pawg neeg, yog hais txog mus rau ib tug monatomic qeb. Lub xub ntiag ntawm hydroxyl pawg txiav txim seb tus tshuaj thaj chaw ntawm lub substance, raws li zoo raws li cov tshuaj tiv thaiv cov khoom ntawm tsis muaj zog.

Thaum muab cia rau hauv unsealed ntim ethyl cawv suab thiab dej yog absorbed los ntawm cov huab cua. Qhov no yog vim lub fact tias ethanol hais txog ib tug hygroscopic substance. Vim lub fact tias hais tias cov khoom muaj ib tug qauv zoo li dej, nws yuav tsum tau tov nrog nws nyob rau hauv tej proportions.

Ethyl cawv rectified, uas ua rau ib tug muaj ib puag ncig, nws muaj ib tug me ntsis acidic cov tshuaj tiv thaiv. Nws yog ib tug txhim khu kev qha qhov tseeb. Nws muaj ib tug me me npaum li cas organic acids. Cov tshuaj tiv thaiv ntawm lub sib ntshiab ethyl cawv nruab nrab. Nws yuav tsum tau nco ntsoov hais tias.

Yuav tsum hais tias thov mus rau qhov zoo ntawm grain

Lub ntsiab kev sib tw muag los ntawm manufacturers ntawm dej cawv haus, yog ib tug ntau lawm ntawm ethyl cawv ntawm lub siab tshaj plaws zoo. Lub xeev cov qauv thiab lwm yam ntxawg cov ntaub ntawv rau qhov no siab yuav tsum, uas muaj feem xyuam rau cov physico-tshuaj thiab organoleptic tsis. Ethanol yog tau los ntawm ntau yam tej yam ntuj tso cov ntaub ntawv.

Siv thiab ua cov hais tias neeg sawv cev los ntawm ua liaj ua teb raw cov ntaub ntawv yog biotechnological ntau lawm, uas siv kab mob los hloov cov hmoov txhuv nplej rau hauv fermentable suab thaj, thiab ces npaj cov ntaub ntawv uas - ethanol. Tag nrho cov ua sawv ntawm kev txaus sab ntawm grain rau rectification muaj ib tug loj npaum li cas ntawm cov tshuaj thiab txhua yam dab. Txhua yam ntawm cov muaj feem xyuam rau cov organoleptic yam ntxwv ntawm ethyl cawv. Qhov no yuav tau piav tom qab.

Yam rau cov organoleptic yam ntxwv

Nyob rau hauv cov ntaub ntawv no:

• Huv mob ntawm cov khoom rau cov (Pipeline vaporization chamber, Thaum tshav kub kub exchangers, hloov tank).
• Zoo ntawm raw khoom (hom grain, lub tej yam kev mob ntawm cia, raws li txoj cai, thiab tsw al.).
• Usable flowsheet pub npaj (enzymatic Txhua yam, tsoos).
• Cov kev kho mob (freeness, nyob rau hauv ib tug warehouse, nyob rau hauv ntau lawm).
• Siv cov poov xab hom.
• Cov kev kawm ntawm lub fermentation txheej txheem (ntev, kev nce ntawm acidity).
• Pab txhawb nqa ntaub ntawv (antiseptics thiab disinfectants).

Ib tug ntawm cov tseem ceeb tshaj yog qhov zoo tshaj ntawm raw cov ntaub ntawv siv. Qhov teeb meem no nrog nws yog ib qhov nyuaj, vim yog tsis muaj pej xeem mov ntawm grain. Yog li ntawd, lub ib thooj ntawm raw cov ntaub ntawv siv yog xa mus rau lub tuam txhab nyob rau hauv lub sib cog lus. Lawv xaus lus uas txawv lwm ntawm khom nqi.

Rau hnub tim, muaj yog tsis muaj lub teb chaws txheej txheem los yog lwm yam normative thiab kev cov ntaub ntawv, uas yuav kom meej meej txhais tau tag nrho cov uas yuav tsum tau rau grain, siv rau qhov siv thiab ua cov khoom no. Txawm li cas los, ib co ntawm lawv yog tsau nyob rau hauv lub "kev cai rau zus tau tej cov dej cawv los ntawm cov hmoov txhuv nplej-muaj raw cov ntaub ntawv." Cov lawv - cov ntsiab lus ntawm ntau yam tshuaj lom kab mob (noob nroj, etc ...), Kab Tsuag kab ntawm grasses, raws li zoo raws li tsim kom muaj av.

Kev siv cov alcohols nyob rau hauv qhov siv thiab ua haus dej haus cawv yuav tsum tau ib tug siab zoo ntawm cov uas ua khoom. Los ntawm lub xeev ntawm cov grain siv yog ncaj qha nyob rau hauv lub organoleptic thaj chaw ntawm lub resulting therefrom hais tias substance. Qhov loj tshaj qhia ntawm lub raw khoom yog nws tsis hnov tsw. Vim lub capillary-ntxeem tau qauv ntawm cov grains thiab coj loj skvazhistosti nws yuav adsorb (nqus) qhov sib txawv gases thiab vapors ntawm cov ib puag ncig. Cov raw khoom uas yog tus kab mob cia kab, tej zaum kuj muaj cov khoom ntawm lawv lub neej. Yog hais tias lub grain mub yog tam sim no, nws worsens cov xim thiab saj, tab sis kuj tsim ib lub tsw. Kev puas tsuaj rau no sheath ntaub ntawv tsim paaj tej yam kev mob rau txoj kev loj hlob microbial thiab txuam nrog ntawm mycotoxins. Siv no grain los tsim li sai tau. Txawm li cas los, cov xov tooj ntawm kab adversely muaj feem xyuam rau cov organoleptic yam ntxwv ntawm lub resulting haus dej cawv.

Rau lub chaw ua khoom ntawm hais tias cov khoom no yog feem ntau ntawm cov neeg pluag zoo siv thiab cov puas grain, cov uas tsis paub qab hau thiab freshly tua, puas kom qhuav, raug rau nws tus kheej-cua sov, thiab lub qhov txhab ergot smut thiab Fusarium. Nws yog ib tug txhim khu kev qha qhov tseeb. Thaum lub sij hawm ua ntawm freshly tua nplej rau siav tsis raug technology ua txhaum tshwm sim, uas ua rau yus muaj teeb meem ntawm lub mash thiab, yog li ntawd, tseem ceeb txo nyob rau hauv kev kawm ntawm cov coj compartment.

Cov xim ntawm cov raw khoom, puas los ntawm qhuav, yuav sib txawv los ntawm lub teeb xim av mus rau dub. Nws yog ib qho tseem ceeb kom paub. Lis dub raug rau cov thoob khib nyiab. Raws li ib tug tshwm sim ntawm txoj kev no nws, tsuas yog nws nrog ib tug noj qab nyob zoo. Yog li ntawd, lub permissible tus nqi ntawm hlawv nplej yuav tsum tsis txhob yuav ntau tshaj 10%. Kev siv cov alcohols rau zus tau tej cov zoo dej haus nyob rau hauv excess ntawm no daim duab yog tsis tsim nyog.

Nyoo kab mob ergot thiab smut yuav lom, txij li thaum nws muaj ntau yam alkaloids (argonin, ergotamine, kortunin etc.). Teeb meem impurities yog heev undesirable, vim hais tias lawv feem xyuam rau txoj organoleptic ntsuas ntawm dej cawv thiab muab nws sharpness, bitterness thiab pungency. Txawm li cas los, cov nqaij nyoos ntaub ntawv uas yuav tau nrog ib tug noj qab nyob zoo grain. Yog li nws cov ntsiab lus yuav tsum tsis muaj ntau tshaj li 8-10 hom%.

Lis, uas yog siv rau kev haus cawv ntau lawm, muaj cov hmoov txhuv nplej (65 - 68% nyob rau hauv qhuav tshuaj yeeb dej caw) raws li protein, rog, free suab thaj, minerals, polysaccharides, dextrin. Tag nrho cov uas muaj npe tebchaw nyob rau hauv ntau yam ua sawv ntawm txoj kev muab kev koom tes nyob rau hauv ntau yam biochemical kev tig cev.

Lwm yam uas muaj feem xyuam rau cov organoleptic thaj chaw ntawm cov khoom tiav yog ib tug malt thiab fermentation npaj mikroorganizmennyh cov qoob loo (saccharifying ntaub ntawv). Nws yuav tsum raug coj mus rau hauv tus account. Heev feem ntau tus kab mob cov tshuaj yuav tsum tau siv nyob rau hauv raug. Nws tseem yuav tshwm sim hais tias lawv tuaj los ntawm ib tug tsis muaj kev enzymatic. Nyob rau hauv xws li ib tug cov ntaub ntawv no tshwm sim tus kab mob fermentation txheej txheem. Cov no yog ib tug tsim-up ntawm pliaj cov khoom pov tseg ntawm cov poov xab. Yog li ntawd, oxidation cawv tsawg. Vim hais tias ntawm no, nws yog tsis zoo heev tshaj tsis hnov tsw thiab saj.

Qhov zoo tshaj ntawm cov dej cawv ncaj qha nyob rau ntau hom poov xab siv. Lawv zoo xaiv thiab characterization ntawm competent fermentation tso cai rau kom muab tau hais tias cov khoom muaj ib tug uas tsis muaj cov ntsiab lus uas yooj yim impurities.

Nws tseem yog ib qho tseem ceeb tivthaiv nyob rau hauv zus tau tej cov dej cawv yog dej. Los ntawm nws kev coj dawb huv (tus nqi ntawm kab mob tam sim no, thiab ntau yam yaj nyob rau ntawd Tshuaj) zoo ntawm cov khoom ua nyob. Nws yog qhov zoo tshaj plaws los mus siv dej los ntawm artesian springs.

Tsis tas li ntawd nco ntsoov tias tom qab tu khoom nyob twj ywm nyob rau hauv hais tias ntau yam tshuaj lom kab mob. Dua esters yog tej zaum tam sim no nyob rau hauv lub ua cawv, yuav impart ib lub teeb, ib tug faint fruity tsw. Nws yog ib tug txhim khu kev qha qhov tseeb. Tab sis muaj cov diethyl ether muab lub npe hu khoom bitterness thiab putrid tsw.

Qhov zoo tshaj ntawm cov tshuaj yeeb dej caw thiab nws organoleptic yam ntxwv kuj los ntawm ntau yam atypical impurities los yog lwm yam microbial toxins, tshuaj tua kab thiab lwm cov neeg.

cawv ua technology

Cov khoom no yog ib tug los ze zog saib. Rectified ethyl cawv tau nyob rau hauv peb txoj kev: los ntawm tshuaj, khoom cua thiab biochemical (enzymatic). Lawv xaiv nyob ntawm tus neeg.

• Enzymatic txheej txheem rau qhov kev npaj ntawm qab zib cawv fermentation tshwm sim. Nws nemaloznachimy txheej txheem. Nws nqa tawm qhov kev txiav txim ntawm cov poov xab thiab enzymes.
