Oil Solvent Extraction Machine
Oil extractor is the most important machine of cooking oil solvent extraction plant,and its quality is directly related to various economic and technical indicators of extraction production.
Working Principal of Edible Oil Solvent Extraction
Solvent extraction is an advanced oil manufacturing method widely used in the world. The process includes solvent extraction,miscella separation, wet meal desolventizing and drying, and solvent recovery.
Solvent extraction adopts a selected organic solvent that can dissolve oil to extract oil from pretreated oilseeds or pre-pressed cake by immersion or percolation in the oil extractor. The mixed liquor obtained is called miscella. The wet meal is discharged from the meal outlet and sent to the desolventizer toaster to remove the solvent. The thick miscella is filtered and sent to the evaporation system. Utilizing the difference of boiling point between the selected solvent and oil, after miscella evaporation and stripping, the solvent evaporates and separates with oil, thus the crude extracted oil is obtained. The solvent vapor is condensed and cooled for reuse. The crude oil is sent to the refining workshop and undergoes a series of refining processes such as degumming,de-acidification, bleaching, and deodorization to obtain the edible oil.
Rotary Extractor
The Rotary Extractor is the most commonly used cooking oil extractor. Its main characteristics are high material layer, high mixed oil concentration, simple structure, and convenient operation and maintenance.
Rotocel extractor is suitable for the oil extraction of peanut, rapeseed, cottonseed, sunflower seed, sesame, corn germ, camellia seed, flax seed, castor seed, soybean, rice bran, safflower seed, palm fruit cake, palm kernel cake, copra, grape seed, evening primrose seed, etc. The extractor is especially suitable for the extraction of various pre-pressed oil cakes. Rotocel extractor is also used for extracting capsicum red pigment.
Chain Extractor
The chain extractor is used for various oil extraction. Its structural feature is that the annular structure separated from the upper and lower layers is merged into a unified box-type structure. Under the action of the turning mechanism, the material can be turned completely, so the permeability is very good.
Loop Type Extractor
Loop type extractor is a continuous combined type extractor suitable for large-scale oil extraction plants. Dragging by the drag chain conveyor, the materials rotate for one cycle to complete the extraction process. The loop-type extractor is suitable for the oil extraction of peanut, rapeseed, cottonseed, sunflower seed, corn germ, camellia seed, flax seed, soybean, rice bran, evening primrose seed, etc.
