Product Description
Cooking oil extractor mainly includes rotocel extractor, loop type extractor and towline extractor. According to different raw material , we adopt different type extractor. Rotocel extractor is the most widely used cooking oil extractor at home and abroad, it is the key equipment for oil production by extraction. Rotocel extractor is the extractor with a cylindrical shell, a rotor and a drive device inside, with simple structure, advanced technology, high safety, automatic control, smooth operation, less failure, low power consumption. It combines spraying and soaking with good leaching effect, less residual oil, the mixed oil processed through internal filter has less powder and high concentration.It is suitable for pre-pressing of various oil or disposable extraction of soybean and rice bran.

The leaching process of rotocel extractor:
Rotocel extractor leaching process is a high material layer counter current leaching. The transmission to drive the rotor and the rotor material within the rotation by a fixed sprinkler system mixed oil spray, soak, drain, rinse with fresh solvent in order to achieve the extraction of material oil, then taking the oil feed meal after a feeding device unloaded out.

When leaching, first by the sealed material embryo auger, according to production requirements even feed grid. After leaching cell memory is full of materials, along the direction of rotation turn around, you can feed in order to complete the cycle spray and drain, washed with fresh solvent, and finally drained out meal, forming a cycle to achieve continuous production.
The two-tier flat rotocel extractor has a strong leaching effect with the following features.


Features OF THE Solvent Leaching Oil Plant: Loop Type Extractor:
1. It has the features of simple structure, smooth operation, low power consumption, low failure rate, high extraction efficiency, easy maintenance and suitable for a variety of oil.
2. The leaching device is driven by the whole casting gear rack and special rotor balance design, with stable operation, low rotating speed, no noise, low power consumption and long service life.
3. The fixed grid plate of rotocel extractor is made of stainless steel and the crosswised grid plates are added, so that the strong miscella oil is prevented from flowing back to the blanking case, thereby ensuring the oil leaching effect.
4. Using γ ray material level to control the feeding, which fully guarantees the feeding uniformity and stability, so that the material level of the storage tank is maintained at a certain height, which plays the role of material sealing to avoid running of the solvent, also greatly improves the leaching effect.
5. The feeding device adopts the material stirring pot with two stirring wings, so that the materials falling instantly can be continuously and uniformly unloaded into the wet meal scraper, which not only absorbs the impact on wet meal scraper, but also realizes uniform scraping of the wet meal scraper, thus completely solves the instability of the hopper and wet meal system and prolongs the service life of the scraper as well.
6. The feeding system can adjust the rotating speed of airlock and main engine according to the feeding quantity and maintain a certain material level, which is beneficial to the micro negative pressure inside the extractor and reduce the solvent leakage.
7. The advanced miscella circulation process is designed to reduce the fresh solvent input, reduce the residual oil in meal, improve the miscella concentration and save energy by reducing the evaporation capacity;
8. The multilayer of material, high concentration of mixed oil, less meal contained in mixed oil. The high material layer of the extractor contribute to form immersion extraction and reduce the content of meal foam in miscella. It is effective improve the quality of crude oil and reduce the scaling of evaporation system.
9. Different spray process and height of material layer are used for the treatment of different materials. Adopting the combination of heavy spraying, forward spraying and self-spraying effect as well as frequency conversion technique, the optimal spraying effect can be reached by adjusting the rotary speed of rotocel extractor according to oil content and thickness of material layer.
10. Suitable for extraction of various pre-pressed cake, say, rice bran puffing and pretreatment cake.

Rotocel extractor is the key equipment for oil production by extraction，which is directly related to the economic and technical indexes of oil production.Therefore, a reasonable choice of rotocel extractor is very important for improving the efficiency of oil production, reducing production costs, and improving the economic efficiency of oil plants.The rotary leaching process is the most widely used leaching method at present, and the rotocel extractor is one of the main equipment in the complete equipment of leaching oil.It can be continuously operated and can extract leaching of cottonseed, soybean, rapeseed, peanut, sunflower seeds, and other plant oils.It is also widely used in the extraction of peppermint oil, pepper red pigment, palm oil, wheat germ oil, corn germ oil, grape seed oil, and evening primrose oil.

Fotma rotocel extractor realizes the good contact between the solvent and the material and the rapid drain, the material germ-layer extraction completely, it is very advantageous to reduce the oil content of the meal and the solubility of the mixed meal, the design of the rotocel extractor has a material level controller, the material level controller and the frequency-modulated motor of the leaching machine, which can keep the raw meal bed with certain material level.On the one hand, it can support the rotocel extractor, on the other hand, the action of the frequency-modulated motor can keep the material level of the rotocel extractor and the wet meal flow balance of the stripping machine.In addition, the rotocel extractor has small power, smooth movement, low failure rate, no noise, low failure rate, easy maintenance, and is one of the advanced rotocel extractor.

Introduction:

Rotocel extractor is the extractor with a cylindrical shell, a rotor with several and a drive device inside.Rotocel extractor includes loose bottom(false bottom) extractor, fixed bottom extractor and double layer extractor. Loose bottom rotocel extractor is widely used in domestic oil processing plant in the 1980s. After the 1990s, fixed bottom rotocel extractor became popular, while the loose bottom rotocel extractor was gradually being phased out. Fixed bottom rotocel extractor has the features of simple structure, easy manufacture, low power consumption, smooth operation and less failure. It combines spraying and soaking with good leaching effect, less residual oil, The mixed oil processed through internal filter has less powder and high concentration, and has been used widely. It is suitable for pre pressing of various oil or disposable extraction of soybean and rice bran.

It has the features of multilayer of material, high concentration of mixed oil, less meal contained in mixed oil, simple structure, smooth operation, low failure rate, easy maintenance and so on. Our company is experienced in the design and production of large rotocel extractor.
2.The fixed grid plate of rotocel extractor is made of stainless steel. The transverse grid plate is added, so that the concentrated mixed oil is prevented from flowing into the drop case, thereby ensuring the leaching effect.
3.Using γ ray material level to control the feeding, which fully guarantees the feeding uniformity and stability, so that the material level of the storage tank is maintained at a certain height, which plays the role of material sealing to avoid running of the solvent, also greatly improves the leaching effect.
4.The feeding device adopts the material stirring pot with two stirring wings, so that the materials falling instantly can be continuously and uniformly unloaded into the wet meal scraper, which not only absorbs the impact on wet meal scraper, but also realizes uniform scraping of the wet meal scraper, thus completely solves the instability of the hopper and wet meal system and prolongs the service life of the scraper as well.
