Abstract

The invention relates to a method for comprehensively utilizing oil residues and in particular relates to a method for producing feed oil and corn germ meal feed by adopting dehydrated oil residues. The method for producing feed oil and corn germ meal feed by adopting dehydrated oil residues, disclosed by the invention, comprises the following steps: leaching the dehydrated oil residues by adopting normal hexane, filtering to obtain mixed oil and filter residues, distilling the mixed oil to recover the solvent and feed oil, and adding the filter residues into the corn germ meal. According to the method disclosed by the invention, the problem that the dehydrated oil residues are colloidal and difficult to transport and are difficultly utilized in feed factories is solved; and a novel feed oil source is developed, the phosphorus content of the corn germ meal feed is improved, and the quality of the feed is improved.

Description

technical field [0001] The invention relates to a method for comprehensive utilization of oil bottoms, in particular to a method for producing feed oil and corn germ meal feed by using dehydrated oil bottoms. Background technique [0002] Corn oil refining is divided into degumming, decolorization, dewaxing, deodorization and other processes. Among them, the soap-free refining process is a new oil refining process that has emerged in recent years. Crude corn oil is hydrated and degummed by adding phosphoric acid, adding light alkaline water to neutralize phosphoric acid, washing with water to separate the two phases to obtain oil feet, and evaporating to remove water to obtain dehydrated oil feet. Dehydrated oil feet are generally supplied to feed mills, but they have the disadvantage of being gelatinous in physical properties and difficult to transport. If the water content of the oil foot is increased, the economic benefit will be poor. Therefore, the storage and handlin...
