Soybean Roj Ntau Lawm Kab

Soybean roj ntau lawm txheej txheem:

1. Cov txheej txheem rho tawm: taum pauv → ntxuav → crushing → softening → flaking → immersion khoom → cia lub thawv → kaw stirring tawb → extractor → tuab tov roj

2. Cov txheej txheem kev kho roj sib xyaw: pom → sib tov Cov roj cia tank → diyi evaporator → thib ob evaporator → stripping ntauwd → roj crude

3. Crude roj refining txheej txheem: hydration huv cov roj → nqus deodorization → lim huv si roj → preheating → ntxiv dej rau hydration → sawv los nag → sib cais → │ Soybean roj ko taw → cua sov → ntsev tawm → sedimentation → rov qab taum taum roj.

Cov ntsiab lus tseem ceeb ntawm soybean roj cov txheej txheem: 

1. Flaking yog tus yuam sij rau pretreatment, uas muaj feem xyuam rau cov txiaj ntsig thiab cov roj zoo. Tus yuam sij rau flaking yog nyob rau hauv kev ua haujlwm ntawm lub tshuab flaking. Txhawm rau kom ntseeg tau qhov zoo ntawm flaking, noo noo thiab kub ntawm cov khoom ua ntej flaking yuav tsum tau tswj nruj me ntsis. Nws yog qhov zoo tshaj rau nruab ib lub thawv softening ntawm lub pob zeb zeb kom tsis txhob poob dej ntau dhau thiab kub tom qab muag muag. Ua ntej pib lub tshuab, ua tib zoo xyuas cov kev ua haujlwm ntawm lub tshuab flaking. Yog tias koj pom tias cov pob zeb ntawm ob qhov kawg tsis sib npaug hauv cov tuab, lossis cov roj tsis sib xyaw yog sib xyaw rau hauv cov pob zeb, koj yuav tsum nres lub tshuab rau kev tshuaj xyuas thiab kho qhov kev ncua deb (qhov kev sib npaug yuav tsum tau ua ntawm ob sab, thiab tsis txhob kho nruj heev. ). Xyuas seb lub scraper yog nruj nreem txuas rau saum npoo ntawm yob kom tsis txhob lo rau yob. Ua tib zoo saib xyuas qhov sib xws ntawm kev ntws thiab tiv thaiv tsis muaj kev thauj khoom.

2. Tus nqi ntawm cov khoom nyob rau hauv txhua lub cell ntawm lub extractor yog 80-85 feem pua, qhov kub ntawm cov kuab tshuaj yuav tsum tau tswj ntawm 50-55 degree, qhov kub ntawm soybean embryos yog 50-55 degree, thiab qhov kub ntawm lub extractor yog 50 degree . Nws yog qhov zoo dua los siv cov tshuaj tsuag loj loj dripping qhuav txau txoj kev, cov kua theem ntawm cov tshuaj tsuag yuav tsum yog 30-50 hli siab tshaj ntawm cov khoom nto, thiab cov kuab tshuaj tshiab yuav tsum tsis txhob dhau mus rau hauv ntu qhuav thaum txau. Solvent ratio (qhov piv ntawm hnyav hnyav rau leaching khoom hnyav) 1:0.8-1.1. Cov kuab tshuaj tsis muaj tshuaj lom raug xaiv, uas yuav tsum tau ua kom tsis muaj zog rau cov roj thiab cov rog, ruaj khov hauv cov khoom siv tshuaj lom neeg, tsis muaj hluav taws kub, tawg, nqaim hauv qhov kub kub ntau, tsis tshua muaj dej solubility, tsis muaj corrosive rau tshuab, thiab tsis muaj tshuaj lom neeg. reactive nrog roj residues.

3. Master kev khiav hauj lwm ntawm lub steamer. Thaum cov pluas noj nkag mus rau hauv diyi txheej ntawm lub tshuab ziab khaub ncaws thiab tshuab ziab khaub ncaws, vim tias cov pluas noj muaj cov kuab tshuaj ntau dua, qhov kub thiab txias yuav tsum tsis txhob nce siab los yog siab dhau, thiab nws yog qhov zoo dua los tswj nws ntawm 65-75 degree; Qhov kub ntawm cov txheej thib ob yog tswj ntawm li 85 degree . diyi, txheej thib ob yog txau nrog cov pa ncaj qha, thiab cov haujlwm ntawm cov enzymes puas tsuaj raug puas tsuaj thaum cov kuab tshuaj evaporating. Tus nqi ntawm kev txhaj tshuaj ncaj qha yog 5-6 kg / ton ntawm cov khoom. Los ntawm txheej thib peb mus rau txheej kawg, lub interlayer yog rhuab los ua lub luag haujlwm ntawm cov khoom ziab. Qhov kub yog 100-105 degree , thiab lub sijhawm steaming yog li 40 feeb. Cov dej sib xyaw ua ke ntawm cov dej thiab cov kuab tshuaj evaporated los ntawm cov pluas noj ntub dej tom qab ziab yog feem ntau los ntawm qhov siab Lub qhov hluav taws xob cov yeeb nkab nyob rau sab saum toj ntawm thawj pem teb yog tawm nrog me me ntawm plua plav plua plav (tshem cov plua plav plua plav no yog qhov zoo rau cov kuab tshuaj thiab kev ruaj ntseg ntawm cov khoom siv rov qab). Cov zaub mov qhuav qhuav yog tawm los ntawm qhov hluav taws xob ntawm cov txheej txheem qis ntawm lub tshuab ziab khaub ncaws (tsis suav cov pluas noj qhuav nrog cov dej noo ntawm 18-20 feem pua), thiab qhov ntsuas kub qis dua 40 degree.

4.Cov txheej txheem kev kho cov roj sib xyaw yuav tsum nruj me ntsis tswj qhov kub thiab txias. Tom qab stripping, yog tias qhov concentration ntawm cov roj sib xyaw tsis ua raws li qhov yuav tsum tau ua ntawm kev ua haujlwm evaporation, ib feem ntawm cov roj sib xyaw yuav tsum txuas ntxiv mus thiab evaporate.

5. Refining yog ua kom cov roj taum pauv tau zoo raws li tus qauv siv tau. Nyob rau hauv tus txheej txheem ntawm refining high-temperature hydration kev kho mob, nws yuav tsum tau muab sau tseg tias thaum ntxiv dej, qhov kub ntawm preheated soybean crude roj yog 55-75 degree . Cov dej tuaj yeem ntxiv los ntawm kev txau cov dej ncaj qha, cua sov lossis siv chav dej thiab dej hauv peb txoj kev. Cov ntsiab lus phospholipid nyob rau hauv cov kua txiv hmab txiv ntoo rho tawm yog 3-4 feem pua, thiab cov dej ntxiv yog 2-3.5 npaug ntawm cov ntsiab lus phospholipid, thiab cov dej kub yuav tsum tsis txhob qis dua cov roj kub. Thaum ntxiv dej, thaum phospholipid micelle tuaj yeem raug tshem tawm hauv cov roj rau lub sijhawm ntev thiab tsis yooj yim rau kev sib sau ua ke thiab tsim flocculent precipitates, ntxiv dej sai dua; txwv tsis pub, nws yuav tsum tau qeeb. Thaum lub sij hawm hydration, tus naj npawb ntawm rotations ntawm lub stirring hniav (inclination 40-45 degree ) yog 60-70 rpm thaum pib (140-180 rpm rau hom ncua kev kawm ntawv), thiab ces qeeb mus rau {{9 }} rpm tom qab tsim cov phospholipids . Thaum cov roj kub nce mus txog 140 degree thiab lub tshuab nqus tsev kawm ntawv nce mus txog 93325 Pascals (700 mm Hg) thaum lub sij hawm hydration, nws yuav nyob ruaj khov. Cov ntsiab lus hnyav hauv cov roj taum pauv tom qab deodorization yuav tsum qis dua 50 mg / kg.

6. Cov khoom siv uas xav tau rau cov roj taum qhuav: vibrating tiaj sieve, pob zeb tshem tawm, cov hlau nplaum ruaj khov nruas, cua tshuab cais, tshuab ziab khaub ncaws, centrifugal pulverizer, sov taum lub thawv, softening lauj kaub, chav stirring tawb, ob chav dov Embryo tshuab, extractor, scraper conveyor, desolventizing roasting tshuab, cov ntaub ntawv siab txheej steaming thiab ziab tshuab, ntxiab, lim, tov roj tank, diyi evaporator, thib ob evaporator, stripping ntauwd, condenser, Dej separator, tshuav tank, distilled dej tank, thiab lwm yam.
