Nyob rau hauv ib txwm kub thiab siab ({{0}}}.3 MPa rau 0.8 MPa), siv butane ua cov kuab tshuaj los rho tawm cov khoom nquag ntawm marigold granule los ntawm txee tam sim no extraction, thiab tom qab ntawd lub tshuab nqus tsev evaporation ntawm cov kuab tshuaj extract thiab pluas noj yuav pib, cov roj hnyav tom qab evaporation yuav dhau los ntawm compression thiab condensation rau kev siv dua tshiab. Ib feem ntawm cov cua sov rau cov kuab tshuaj evaporation los ntawm qhov system nws tus kheej. Lwm qhov ntawm cov cua sov yog muab los ntawm cov cua sov.
Cov txheej txheem rho tawm
Ua ntej, lubmarigoldpaj granule raug thauj mus rau lub tank cia, thiab tom qab ntawd lub conveyor nkag mus rau hauv lub tank extraction. Cov txheej txheem rho tawm tam sim no yog tsim nyob rau hauv lub tank extraction ntawm marigold paj granules thiab hnyav. Cov paj tshiab uas tau nkag mus rau marigold yog soaked nyob rau hauv ib tug siab concentration ntawm extracts, ces cov concentration ntawm cov extracted kua yog txo nyob rau hauv lem, thiab siv cov tshiab hnyav nyob rau hauv lub xeem counter tam sim no extraction txheej txheem. Kev rho tawm zaus yog 4 ~ 6 zaug. Lub sij hawm rho tawm ntawm 120-180 feeb, qhov ntsuas kub yog 45 degree, cov lutein residual nyob rau hauv cov pluas noj yog tsawg tshaj li hauv qab no 0.5 feem pua, extract concentration yog 20 ~ 25 feem pua. (Nyeem ntau ntxiv txog cov noob txiv ntoo roj extraction txheej txheem.
Cov txheej txheem ntub dej desolventizing
Thaum cov pluas noj ntub yog nyob rau hauv extractor, siv indirect steam rau chav hnyav. Ua ntej, siv compressor tshem tawm cov kuab tshuaj los ntawm decompression desolventizing, tom qab ntawd siv lub tshuab nqus tsev tsis zoo kom tshem tawm cov kuab tshuaj thaum qhov kub tuaj txog ntawm qee qhov siab, thaum kawg, cov kuab tshuaj yog steamed tawm ntawm pluas noj. Tom qab desolventizing kev kho mob, cov residual hnyav nyob rau hauv cov pluas noj yog hais txog 700 qhov chaw ib lab, cov dej noo nyob rau hauv cov pluas noj yog tsawg tshaj li 12 feem pua, qhov kub ntawm cov zaub mov desolventizing yog 40 degree nyob ib ncig ntawm. Tom qab ntawd, cov pluas noj tuaj yeem xa mus rau lub tsev khaws khoom noj rau kev ntsuas, pob thiab khaws cia.
Extract txheej txheem
Lub extraction ntawm lub extraction tank mus los ntawm extract lim thiab extract tank kom tshem tawm pulp ua npuas ncauj, thiab ces cov kuab tshuaj yog tshem tawm los ntawm nws los ntawm decompression. Cov kuab tshuaj residual ntawm extract tshem tawm cov kuab tshuaj s tsawg dua 500 qhov chaw ib lab, thiab qhov kub thiab txias yog 55 degree. Lub extraction kua concentration system yog ua nyob rau hauv tsis zoo siab los xyuas kom meej tias cov kuab tshuaj yog yaj nyob rau hauv qis kub.
Cov kuab tshuaj los ntawm lub tank extraction, evaporator yog condensed los ntawm lawv tus kheej compressor. Tom qab compressed thiab liquefied, cov kuab tshuaj los rau condenser. Cov kuab tshuaj condensed yog rov ua dua tshiab rau hauv lub tank rov ua dua tshiab, thiab cov roj uas tsis yog-condensable hnyav tau tso tawm ib ntus los ntawm cov channel ruaj khov.
