solvent extractor

During the process of solvent extraction, the most two popular types of extractors are Rotary extractor and loop extractor.

Rotary Extractor

Rotary extractor is popular for various pre-pressed oil cakes which has adopted a variable voltage variable frequency (VVVF) drive with an adjustable rotation speed. A chain transmission imparts smooth, reliable operation. The fixed-plate grid is made of stainless steel. Its precision 18-cell design and transverse plate grid prevents concentrated miscella from flowing to incorrect chambers. The loop extractor, however adopts a chain driving system. This kind of solvent extractor ensures less power consumption, less maintenance, and reduces noise. The rotation speed of loop extractor can be adjusted automatically according to incoming oilseed's quantity to ensure that the bin level is stable. This will help to form micro negative-pressure in the extractor to prevent the escape of solvent gas.

 Features of the Rotary Extractor

• The rotary extractor adopts a rack driving system. The unique rotor balancing process ensures less power consumption, less maintenance and less noise.
• The rotation speed of the air lock and rotor extractor can be adjusted automatically according to the incoming oilseed quantity to ensure that the bin level is stable. This will help to form micro negative pressure in the oil seed extractor and prevent solvent escaping from the oil extractor.
• Miscella circulation is improved to reduce solvent usage, solvent residue in meal and to increase the miscella concentration. Energy is saved by reducing evaporation.
• The rotating extractor is popular for many kinds of pre-pressed cake. The rotation cell at the upper bin level makes it easy to perform immersion extraction and reduces meal fines in the miscella. All this will help improve the quality of crude oil and reduce scaling in the evaporation system.

Loop Type Extractor

The loop type extractor adopts a chain driving system. It is one potential extraction method available in the solvent extraction plant. The new loop-structure ensures less power consumption, less maintenance, and reduces noise. The rotation speed of Loop-type extractor can be adjusted automatically according to incoming oilseed's quantity to ensure that the bin level is stable. This will help to form micro negative-pressure in the extractor to prevent the escape of solvent gas.

 Features of the Loop Type Extractor

• The loop extractor is designed with a chain drive, frequency controlled motor speed, unique circular structure, low rotating speed, low power consumption. It runs smoothly and silently with low maintenance costs.
• An advanced miscella circulating schematic design decreases the need to input fresh solvent. The residual oil in dregs of rice is reduced, improving the miscella’s concentration. Energy is saved by cutting down on evaporation.
• The material bed in the extractor is low and uses percolation leaching. To prevent dead spots in the leaching process, materials at the curved section will be turned. In cases of significant dregs in the miscella is high, the dregs are effectively disposed of before entering the evaporation system.
