Generally speaking, rotary oil extractor and loop oil extractor are two of the most popular oil solvent extractors in the process of oil solvent extraction.
Loop Oil Extractor
Loop oil extractor adopts a chain driving system and has many advantages, like: less power consumption, less maintenance, and low noise. The rotating speed of loop extractor can be adjusted automatically according to the quantity of incoming oilseeds, which ensures the level of the bin is stable. All of these help to form micro negative-pressure in the extractor to prevent the escape of solvent gas.
Features of Loop Oil Extractor
1. The loop oil extractor is designed with a chain drive, frequency controlled motor speed, unique circular structure, low rotating speed, and low power consumption. It runs smoothly with low maintenance cost.
2. Its advanced miscella circulating schematic design decreases the usage of fresh solvent. The residual oil in dregs is reduced, which improves the miscella’s concentration. Energy is also saved by cutting down on evaporation.
3. The material bed in the extractor is low and it adopts percolation leaching. To prevent dead spots in the leaching process, materials at the curved section will be turned. In cases that significant dregs in the miscella is high, the dregs are effectively disposed of before entering the evaporation system.
Rotary Oil Extractor
Rotary oil extractor adopts a variable voltage variable frequency (VVVF), and it is very popular for many different pre-pressed oil cakes. Its rotating cell design at the top bin level makes it easy to perform immerse extraction and to reduce the meal fines in the miscella, which improves the quality of the crude oil by reducing scaling in evaporation system. The extractor is driven by gear rack. The unique balancing rotor is designed to ensure less power consumption, less maintenance cost and less noise.
Features of Rotary Oil Extractor
1. It adopts a rack driving system. The unique rotor balancing process ensures less power consumption, less maintenance cost and less noise.
2. The rotating speed of air lock and rotor extractor can be adjusted automatically according to the oilseeds’ quantity to ensure that the bin level is stable. This will help to form micro negative pressure on the oilseed extractor and prevent solvent escaping from the oil extractor.
3. Miscella circulation is improved to reduce solvent usage, solvent residual in meal and to increase the miscella concentration. Besides, energy is saved by reducing evaporation.
4. The rotary oil extractor is very popular for many kinds of pre-pressed cake. The rotating cell design at the top bin level makes it easy to perform immerse extraction and to reduce the meal fines in the miscella. All of these help a lot to improve the quality of the crude oil by reducing scaling in evaporation system.
