The process of preparing rapeseed oil by leaching oil equipment technology:
Rapeseed → cleaning → softening → rolling embryo → steaming and frying → pre-pressing → pre-squeezed cake-leaching → mixed oil evaporation and steam stripping → leaching crude oil ↓ ↓ machine pressing crude oil ← filtration desolventization → rapeseed meal
Main process parameters:
(1) Cleaning: Remove impurities in rapeseed, and the content of impurities after cleaning should not exceed 0.5%.
(2) Softening: The softening temperature is 50-60℃, the moisture is about 9%, and the softening time is 12min.
(3) Rolled embryo: The thickness of the rolled embryo is about 0.35mm, which is less powdery and does not show oil.
(4) Steaming and stir-frying: the discharging moisture is 4-6%, and the discharging temperature is about 110℃.
(5) Pre-squeezing: using an oil press, the squeezing water is 4-5%, the squeezing temperature is about 110℃, and the oil content in the cake is about 12%.
(6) Leaching equipment: Use No. 6 solvent oil, the general temperature is 50-55℃, the immersion solvent to material ratio is 1.6-2:1, and the spray leaching solvent to material ratio is 0.3-1:1 , The concentration of mixed oil is controlled at 10-25%.
(7) Desolubilization: The temperature of the meal is 105-110℃, and the moisture content is below 10-12%.
(8) Evaporation: The discharge temperature of the mixed oil is not more than 120℃, and the water vapor is 0.2-0.4Mpa.
(9) Stripping: the mixed oil feed temperature is 90-100℃, the feed concentration is 90%, the solvent content is not more than 0.3%; the direct vapor pressure is 0.2-0.3Mpa, the indirect vapor pressure is 0.02-0.04Mpa
