Cov tsev noj mov loj hauv tsev so, chained- cov tsev so thiab cov khw haus dej haus ntau cov dej khov hauv ib hnub, qhov tsis zoo ntawm kev siv ob peb lub tshuab dej khov me me yog lub zog siab thiab dej haus, thiab qhov zoo ntawm cov dej khov yog qhov nyuaj rau kev lav.
Kev Lag Luam Ice Service
Cov tsev so, tsev loj, cov chaw pabcuam dej haus, cov tsev kawm ntawv, cov dav hlau, kev kho mob thiab lwm yam lag luam xav tau cov khoom noj khoom haus tshwj xeeb.
Ntses thiab cov khoom siv nuv ntses yuav tsum tau khaws cia nrog dej khov lossis dej txias los ntawm txhua kauj ruam ntawm kev tuav cov ntses. Txhawm rau kom muaj txiaj ntsig zoo ntawm cov ntses zoo, cov dej khov loj yog xav tau rau kev tswj xyuas qhov kub thiab txias kom txo tau cov kab mob los yog cov enzyme hauv cov khoom noj nqaij nruab deg, qeeb qeeb thiab ua tiav qib siab dua.
Nqaij ua
Thaum lub sij hawm ua cov nqaij, scouring thiab dehairing yog ob txheej txheem ua rau nqaij kub nce, uas cuam tshuam rau cov nqaij zoo.
Ua ntej khaws cia cov nqaij ua tiav, yuav tsum ceev ceev kom khov kom muaj qhov saj thiab zoo ntawm cov nqaij.
Cov txiv hmab txiv ntoo thiab zaub tshiab tshiab muaj "tej tshav kub" uas ua rau cov khoom tawg tau sai dua. Kev tswj qhov kub thiab txias yog qhov tseem ceeb kom tswj tau qhov zoo ntawm ntau hom khoom thiab txuas ntxiv txee- lub neej ntawm cov khoom lag luam horticultural.
Ci Cov Khoom Ua Haujlwm
Cov khoom xyaw chilled dej yog siv los ua khob noom cookie sib tov thiab txias. Cov dej khov yog tov rau hauv lub khob noom cookie rau kev tswj qhov kub thiab txias.
Cov khoom ci, tshwj xeeb yog cov qhob cij, cov yob qab zib, thiab cov buns, yog tsim nyob rau hauv cov ntim loj, nrog rau kev tswj xyuas qhov kub thiab txias thaum lub sij hawm ua khob noom cookie ua lub luag haujlwm tseem ceeb hauv qhov khoom kawg.
Pob zeb yog cov khoom siv siv ntau tshaj plaws hauv kev tsim vaj tsev engineering. Cov pob zeb pouring yuav tsum tau nqa tawm ntawm qhov ntsuas kub kom tsis txhob deformation thiab tawg los ntawm thermal expansion thiab contraction. Kev tsim kom muaj qhov ua tiav ua kom txias txias tau dhau los ua qhov teeb meem tseem ceeb uas tau ntsib los ntawm txhua qhov kev tsim kho nrog rau txoj kev loj thiab kev tsim vaj tse, tshwj xeeb tshaj yog cov haujlwm hauv cheeb tsam kub thiab qhuav.
Kev ua tshuaj lom neeg
Diazo cov tshuaj tiv thaiv, cov tshuaj tiv thaiv sib txuas thiab cov tshuaj tiv thaiv condensation yog peb qhov kev cuam tshuam hauv kev ua tshuaj, thiab lawv kuj yog cov piv txwv ntawm exothermic cov tshuaj tiv thaiv, cov cua sov uas yuav tsum tau tso tawm raws sijhawm. Kev kub siab tsis tsuas yog tuaj yeem ua rau nitrous acid decomposition, tab sis kuj ua rau kom lub decomposition ntawm cov tshuaj sib txuas. Qhov zoo tshaj plaws kub rau cov tshuaj tiv thaiv nyob nruab nrab ntawm 0℃thiab 10 degree.
Hauv kev ua cov khoom noj siv mis, cua sov lossis cua txias ua haujlwm feem ntau ua ke nrog cov txheej txheem ntawm lub cev xws li nplawm lossis sib cais los tsim ntau hom khoom noj siv mis. Qhov zoo ntawm cov khoom siv mis nyuj tuaj yeem cuam tshuam yog tias qhov kub thiab txias yog siab dhau lossis qis dhau. Yog li, kev tswj qhov kub thiab txias thaum lub sijhawm ua haujlwm yog qhov tseem ceeb.
