Edible oil extractor
Edible oil extractor is a kind of equipment for extracting vegetable oil, which is widely used in food processing industry. Its main working principle is to separate oil from oily raw materials by solvent soaking or extraction. Common raw materials include soybeans, peanuts, rapeseed seeds and sunflower seeds.
Working principle of edible oil solvent extraction
Solvent extraction is an advanced oil-making method widely used in the world. The process includes solvent extraction, separation of mixed oil, desolvation and drying of wet meal and solvent recovery.
Types and application of edible oil extractor
Edible oil extractor is the key equipment for extracting vegetable oil, and its types and applications are different according to production requirements. Common types of extractor include drag chain extractor, loop type extractor and tank extractor.
Drag chain extractor is a common continuous extraction equipment, which is widely used in oil processing industry to extract oil from plant seeds. It distributes the materials evenly in the extractor through the drag chain system, and fully soaks the materials with solvent to dissolve the oil in the solvent.
Rotocel extractor is a continuous combined extractor. The rotor composed of material grids rotates around the main shaft once to complete the extraction process. Rotocel extractor is the most widely used edible oil extraction equipment, which is suitable for small and medium-sized oil mills.
Tank extractor is a kind of immersion extractor. Each extraction tank works in batches, including feeding, soaking, steam blowing, stripping and discharging. Several tanks form a continuous extraction process. Tank extractor is suitable for small oil production plants with capacity below 20 TPD.
The continuous optimization of leaching technology not only improves the oil yield, but also reduces the solvent consumption, which is of great significance to green production.
