Ultrasonic cov khoom cawv cawv
Cov dej cawv lub ntsiab lus laus: cov cawv tshiab freshly ua kom tiav cov mos mos, kev sib raug zoo thiab kev ua haujlwm rau lub suab, thiab lub cawv txiv ntoo laus yuav ua tau zoo dua hauv aroma thiab saj.
Laus mechanism:
(1) Txhawb nqa cov koomhaum: txhim kho kev sib raug zoo ntawm cov lwg me, tsis tsuas yog txhim kho qib ntawm kev sib raug zoo ntawm cov cawv dej cawv thiab dej lwg me me, tab sis kuj tseem tuaj yeem ua ib pawg loj dua thiab firmer koom ua ke ntawm cov lwg ncau. Nyob rau tib lub sijhawm, txhawm rau txhawm rau txhim kho cov tshuaj tiv thaiv esterification thiab kev tsim cov tshuaj ester hauv cov kab ke, qee cov esters thiab acids kuj tseem tuaj yeem ua ke nrog pawg koom ua ke no.
(2) Txhim kho lub zog molecular kev ua kom lub zog ntawm ntau yam tshuaj: txhim kho qhov kev sib tsoo ntawm cov qauv sib txawv, ua kom nrawm rau kev ua kom tiav, ua kom yws, rov ua dua thiab lwm yam kev cuam tshuam, uas tau txais txiaj ntsig los ua cov cawv ester brewing tsw ntawm cov cawv.
(3) Ua kom sai ntawm kev hloov pauv ntawm cov roj hauv qab: vim qhov nce ntawm molecular kinetic lub zog, muaj peev xwm muaj cov tshuaj hydrogen sulfide, acetaldehyde thiab lwm cov khoom ntxiv yuav ua kom nrawm khiav tawm ntawm cov cawv, sai sai tshem tawm cov pungent thiab lwm yam ntxhiab.
Ultrasonic irradiation tuaj yeem txhawb kev luam ntawm cov poov xab, ua kom lub sij hawm fermentation luv thiab nce cov aroma ntawm caw. Ultrasound tseem siv los leeb kev laus ntawm caw. Cov cawv txiv neej ua rau lub siab loj ntawm kev co ntawm ultrasonic tsis, thiab lipids yog nrawm los ua ke nrog ethanol thiab dej. Khaws cia rau ib lub sijhawm luv luv, cawv muaj mellow saj, qab zib thiab muag.
Ultrasonic laus ntawm caw nplej tau pom tseeb cuam tshuam. Cov ntsiab lus hloov pauv ntawm cov kua qaub, cawv, aldehyde, kua qaub thiab ester hauv cov cawv yog zoo li ntawd ntawm cov neeg laus ib txwm.
Cov ntxhiab ntawm cov dej cawv yuav hloov tom qab kev kho mob ultrasonic. Kev kho mob ultrasonic tuaj yeem txhawb kev laus ntawm cawv thiab muaj qee yam cawv rau cov cawv cawv, cov kua qaub tag nrho, tag nrho cov rog, cov ntsiab lus methanol, thiab lwm yam.
Qhov kev hloov siab ntawm hops yuav tshwm sim thaum npias yog ultrasonically kho rau 5 feeb, thiab siv ultrasonic tsis nyob hauv npias ntau lawm tuaj yeem txuag raw khoom.
Ultrasonic kev kho mob ntawm cov cawv txiv hmab tsis tuaj yeem tsuas yog hnub nyoog ua cawv txiv hmab, tab sis kuj txiav txim siab tshem tawm cov khib nyiab thiab lwm yam zoo, uas tuaj yeem tsim nyob hauv ob xyoos.
Hauv kev tsim cov txheej txheem ntawm kev noj qab haus huv cawv, ultrasonic vuam siv tau los siv cov khoom xyaw zoo ntawm cov ntaub ntawv tshuaj, thiab cov cawv txiv hmab kuj tseem tuaj yeem raug ultrasonic laus, uas yog lub zoo meej ntawm ntau lub zog.
