Soybean Roj Refining Tshuab

Soybean oil, peanut oil, and sesame oil yog cov roj tseem ceeb hauv kuv lub tebchaws. Yog tias qhov zoo ntawm cov khoom siv raw khoom zoo thiab cov txheej txheem ntawm cov roj extraction yog qhov tsim nyog, cov roj crude zoo zoo dua, thiab cov ntsiab lus ntawm cov roj fatty acid dawb yog feem ntau qis dua 2 feem pua, uas yooj yim rau refine.

1. Crude edible roj refining txheej txheem (batch hom)

dej mos→ Desolvation →Pom cov roj crude → preheating → hydration → stationary sedimentation → sib cais -- → dej-muaj degummed roj → ziab → ntxhib refining edible roj

Yog tias cov roj crude yog refined thiab leached, nag lossis daus kub yog li 160 degree, kev khiav hauj lwm siab tsis ntau tshaj 4.0kPa, thiab lub sij hawm los nag yog 1 ~ 3 teev.

2. Refining txheej txheem ntawm refined edible roj (nruam deacidification, intermittent decolorization thiab deodorization)

Lub adsorption decolorization kub yog 80-90 degree, kev khiav hauj lwm siab siab yog 2.5-4.0 kPa, lub sij hawm ua hauj lwm ntawm decolorization kub yog li 20 feeb, tus nqi ntawm cov av nplaum ntxiv yog 2.5 feem pua ​​{ {23}} feem pua ​​​​ntawm cov roj nyiaj, thiab qhov ntsuas kub thaum sib cais av nplaum sib txawv. Ntau tshaj 70 degree. Hauv cov roj decolorized, p<5 ppm, Fe<0.1ppm, Cu<0.01ppm, no clay, deodorization temperature is about 230°C, operating absolute pressure is 260~650Pa, stripping steam flow rate is 8~16 kg/t h, The deodorization time is 4-6 hours, the amount of citric acid (5%) added is 0.02%-0.04% of the oil, and the safe filtration temperature is not higher than 70°C.
