Method for extracting industrial oil from obtained oil residue after oil manufacture of vegetable

Abstract

The invention discloses a method for extracting industrial oil from obtained oil residue after oil manufacture of vegetable, which solves the defects that in the prior art, water, oil, oil cake and impurities are reserved in obtained oil residue after oil manufacture, so that the obtained oil residue is slabby, occupies large storage area, is exposed to wind, the sun and rain, and pollutes environment as the obtained oil residue flows everywhere; lawbreakers even reuse the oil residue by taking the oil residue as raw materials of illegal cooking oil, as a result, great harm is done to people; and greater harm is done to the environment and people when a chemical squeeze method is adopted. The method is characterized in that the obtained oil residue after oil manufacture of vegetable is heated, mixed with a filter aid, put into a cloth bag and finally squeezed. The method has the advantages that waste is turned into wealth as excess oil is squeezed from the oil residue; the problem, which puzzles oil pressing mills for a long time, that the storage of oil residue not only pollutes environment, but also occupies large area can be solved; meanwhile, illegal activities of taking the oil residue as raw materials of extracting illegal cooking oil are prevented; and the residual oil residue after extracting industrial oil with the method provided by the invention can be used as fertilizer and fuel to extract industrial oil from obtained oil residue after oil manufacture of vegetable.

Description

technical field [0001] The invention relates to the physical separation technology in the international patent classification, in particular to a method for extracting industrial oil from the oil foot after plant oil pressing. Background technique [0002] Extracting oil from plants in the prior art adopts physical and chemical two methods of squeezing. Although the oil in plants can be squeezed and squeezed out using these two methods, its disadvantages are: method, there are still a large amount of water, residual oil, oil cake and other impurities in the oil feet after vegetable oil extraction. It is precisely because of the existence of these residues that the oil feet after plant oil extraction are sticky and not easy to dry; the storage occupies a large area; it flows everywhere after being blown by wind, sun and rain, which is one of the pollution sources of polluting the environment . In addition, what's more, the oil feet after the oil extraction of these plants a...
