AI Technical Summary
Existing technologies for removing phthalates from edible oils suffer from low efficiency, high energy consumption, large solvent usage, and may lead to the loss of vitamin E and the accumulation of plasticizers.
A device for removing hazardous substances from edible oil is used, comprising an oil droplet alcohol bubble detoxification unit, a temporary storage tank, an oil pump, and a centrifugal separation unit. Low-molecular-weight alcohol gas is pressurized to form oil droplet bubbles, which adhere to the mesh of the attachment chamber. Subsequently, the oil droplets are mixed with solvent and stirred, cooled, and centrifuged. Finally, solvent removal is performed to remove the hazardous substances.
It achieves efficient removal of phthalates from edible oils, while reducing energy consumption and solvent usage, improving oil quality, and reducing the formation of trichloropropanol esters and glycidyl esters during subsequent refining processes.
