Dingsheng Machine Unveils Comprehensive Corn Oil Production Solutions
Date:Oct 21st, 2024
Corn oil, also known as maize or corn germ oil, is extracted from the germ of corn kernels, with a high fat content of 17-45%, making up over 80% of the total fat in corn. This valuable oil is processed through a complex, precise procedure involving extraction from corn germ and a series of refinement steps to produce high-quality corn oil. Dingsheng Machine offers fully customized corn oil production lines, covering every stage from raw material handling and extraction to refining and packaging, ensuring high efficiency and quality.
Corn Oil Pre-Treatment Process
The pre-treatment stage focuses on preparing corn kernels for optimal oil extraction, enhancing both stability and purity. The process includes cleaning, de-hulling, and drying, all designed to increase oil yield and ensure the final product’s quality.
Raw Material Preparation and De-hulling
Corn kernels are first cleaned to remove impurities, ensuring purity. The kernels are then moistened for better separation, followed by de-hulling and breaking.
Corn Germ Selection and Pressing
Corn germ is separated from the kernels based on weight and purity, then pressed and screened to prepare for further processing.
Drying and Roasting
Moisture content is reduced to suitable levels for pressing, generally below 4%, using drying and roasting methods to enhance quality.
Corn Oil Extraction Process
There are two main methods of corn oil extraction:
Pressing: Traditional physical pressing extracts oil but may retain some impurities, yielding slightly lower extraction rates.
Solvent Extraction: The more advanced solvent extraction method uses hexane to dissolve the oil from corn germ, then separates it through processes like steaming, stripping, and condensation. This method provides higher yields, though solvent residue must be carefully managed for food safety.
Corn Oil Refining Process
Once extracted, crude corn oil contains impurities and potentially harmful substances. The refining process ensures purity and safety through multiple stages:
Deacidification: The oil is neutralized with alkali to remove free fatty acids and impurities, followed by a soap formation reaction that is carefully heated and mixed.
Decolorization: If needed, color pigments are removed using bleaching agents, producing visually clear oil.
Deodorization: This critical step uses vacuum steam distillation to remove undesirable odors, improving taste and stability. Equipment used includes deodorization tanks, condensers, and vacuum pumps.
Dewaxing: Though corn oil has low wax content, any remaining wax can be filtered out for optimal quality.
