Oil-making process by solvent extraction method
1. The classification of oil-making process by solvent extraction method can be divided into batch extraction and continuous extraction according to the operation mode.
①Batch extraction
The flakes enters the extractor, the meal is discharged from the extractor, the injection of fresh solvent and the extraction of concentrated mixed oil are all batch, intermittent, and periodic leaching processes belonging to this process type.
②Continuous extraction
The flakes enters the extractor, the meal is discharged from the extractor, the injection of fresh solvent and the extraction of concentrated oil are all continuous extraction processes belonging to this process type.
2. According to the contact method, the extraction method can be divided into immersion extraction, percolation extraction and combined extraction
①Immersion extraction
The flakes in the solvent to complete the extraction process is called immersion extraction.
The immersion extraction equipment includes tank type, in addition to redler extractor and Hildebrand extractor,Y-type extractor.
②Percolation extraction
The solvent is in the spray state and contacts the flakes to complete the extraction process, which is called percolation extraction. The percolation extraction equipment includes screen belt type solvent extractor.
③Combined extraction
This is a extraction method that combines percolation and Immersion. The combined extraction equipment includes rotocel extractor and loop type extractor.
3. The oil-making process of extraction method can be divided into direct extraction and pre-pressing extraction according to the production method
① Direct extraction
Direct extraction is also called "single extraction". It is the process of extraction oil directly after pre-treatment of the oil. This process is suitable for processing oil with low oil content.
②Pre-pressing extraction
The pre-pressing extraction oil is pre-pressed to remove part of the oil, and then the cake with higher oil content is extracted. This process is suitable for oils with higher oil content.
①Batch extraction
The flakes enters the extractor, the meal is discharged from the extractor, the injection of fresh solvent and the extraction of concentrated mixed oil are all batch, intermittent, and periodic leaching processes belonging to this process type.
②Continuous extraction
The flakes enters the extractor, the meal is discharged from the extractor, the injection of fresh solvent and the extraction of concentrated oil are all continuous extraction processes belonging to this process type.
