Dab tsi yog txoj kev extraction ntawm cottonseed roj, thiab yuav ua li cas xaiv cov khoom tsim nyog cottonseed extraction khoom?

Muaj ob txoj hauv kev tseem ceeb ntawm cov roj cog qoob loo: ib qho yog pretreatment pressing method, thiab lwm yam yog cov kuab tshuaj extraction txoj kev. Cov txheej txheem sib txawv siv cov khoom siv sib txawv ntawm cov noob roj extraction, yog li yuav ua li cas xaiv cov khoom siv cog qoob loo cog qoob loo? Kab lus no yuav muab cov lus teb rau koj.

• Thawj txoj kev: pretreatment pressing method

Ua ntej, ib qho tshwj xeeb cua cais yog siv los tshem tawm lub teeb impurities thiab hnyav impurities nyob rau hauv cov paj rwb, thiab cov txiv hmab txiv ntoo uas huv si yuav tsum tau muab tshem tawm, thiab cov disc sheller yog siv los ua kom tiav cov nyhuv xav tau. Tom qab ntawd ib lub plhaub plhaub cais yog xav tau los cais lub plhaub ntawm lub kernel, yog li koj tau txais cov ntsiav huv si rau cov kauj ruam tom ntej. Cov kernels ntxuav yuav tsum tau ib tug roaster kom lawv mos thiab yooj yim nias. Qhov tseem ceeb tshaj plaws yog cov txheej txheem nias, xaiv cov roj xovxwm tshuab kom raug, kom cov roj yield yog siab thiab pheej yig dua. Cottonseed roj yog lim los ntawm lub lim xovxwm kom tshem tawm impurities thiab tau txais cov roj huv huv.

• Qhov thib ob txoj kev: hnyav extraction method

Txoj kev no muaj cov roj residual tsawg thiab yog siv dav hauv cov roj extraction. Lub pretreatment theem yog tib yam li cov txheej txheem nias. Thawj txheej txheem ntawm extraction yog cov kuab tshuaj extraction seem. Qhov thib ob txheej txheem yog miscella evaporation thiab stripping. Lub hom phiaj yog tshem tawm cov hmoov coarse thiab cov kuab tshuaj sib cais hauv cov roj, thiaj li kom tau txais cov roj ntshiab uas tau muab rho tawm. Qhov thib peb kauj ruam yog desolventize lub ci mov. Cov hmoov ntub dej tawm ntawm lub tshuab rho tawm feem ntau muaj 20% -40% hnyav thiab yuav tsum tau rov qab los ntawm kev sib cais thiab ziab. Cov kauj ruam kawg yog hnyav rov qab.

Yog li yuav ua li cas xaiv cov cuab yeej zoo los rho tawm cov roj cottonseed? Ib qho yog nyob ntawm tus nqi ntawm cov khoom siv raw, thiab lwm qhov yog raws li kev nqis peev nyiaj txiag.

Yog tias koj lub peev xwm ua tau me me thiab cov peev nyiaj tsawg, nws raug nquahu kom koj xaiv txoj kev nias pretreatment. Cov khoom siv uas yuav tsum tau muaj xws li: cov khoom siv tu, lub tshuab shelling, cov khoom siv plhaub plhaub cais, roaster, roj xovxwm, lim, thiab lwm yam.. Cov txheej txheem tshem tawm cov kuab tshuaj yog tsim rau cov paj noob hlis roj extraction tej yaam num nrog ntau cov ntaub ntawv raw thiab kev nqis peev siab. Ntxiv nrog rau cov khoom siv nias, peb kuj yuav tsum tau siv cov khoom hnyav extraction.
