Extractor is the core equipment of leaching oil production process, and its quality is directly related to various economic and technical indicators of leaching production. The horizontal rotary extractor is the most widely used extractor in our country. Suitable for all kinds of oil crops. It has simple structure, reliable operation, unique rotor balance design, low power consumption, stable and noiseless operation, and extremely low maintenance costs.

   The high material layer rotary design of the extractor is conducive to the formation of immersion leaching and the reduction of the content of meal powder in the mixed oil, which is conducive to improving the quality of crude oil and reducing the fouling of the evaporation system; it has a wide range of applications and is most suitable for pre-pressed cakes of leaching. The structure of the horizontal extractor is mainly composed of a sealed outer shell, a rotor, a fixed grid, a track, a mixed oil collection grid, a spray device, a feeding and unloading device, and a transmission device.

   The leaching method applies the principle of solid-liquid extraction, selects an organic solvent that can dissolve oil, and sprays and soaks the oil to extract the oil in the oil. The basic process of extracting oil by leaching method is to immerse the oil seed embryo, pre-pressed cake or puffed embryo in the selected solvent, so that the oil is dissolved in the solvent to form a mixed oil, and then the mixed oil is separated from the leached solid meal. Evaporate and strip the mixed oil to vaporize the solvent and separate the oil, so as to obtain the extracted crude oil.

  When the horizontal extractor is working, the raw material is sent to the mixing auger through the closed auger to accept the pre-soaking of the mixed oil, and then the wet material falls into the extractor to rotate. Since the raw material is a wet material, the powder flying in the device can be avoided when it is a dry material. With the slow operation of the rotary grid, when the blank in the grid is transferred to the position of the spray pipe, it is sprayed and leached by the sprayed mixed oil. Since the spraying of fresh solvent and mixed oil is in the opposite direction to the direction of the raw material, the concentration of mixed oil leaking into the mixed oil grid after leaching from the grid that has just been put into the raw material is the highest, and the mixed oil overflows to the second stage. The mixed oil grid, the mixed oil leaked from the grid corresponding to the second grid passes through the tent filter. The filtered thick mixed oil is drawn out from this compartment. Then, the grid receives the spray of mixed oil pumped from the next mixed oil grid, and the grid continues to rotate, and the embryos in the grid are subjected to spraying and leaching of the mixed oil pumped in again and again. once thin. Finally, it is sprayed and leached with fresh solvent, and the thinnest mixed oil is collected in the corresponding mixed oil grid. Meanwhile, the mixed oil pumped into the mixing auger is extracted from the II mixed oil grid. After being drained for a period of time, the material grid has been transferred to the meal falling place. At this time, the lower part of the turntable is a false bottom, and the copper roller slides along the downward track, and the false bottom is automatically opened to release the wet meal. The lower part of the grid is a fixed grid bottom, and the wet meal is scraped to the gap by the grid and falls. The wet meal dropped in the meal hopper is then taken over by the scraper conveyor at the next destination and sent to the steamer for processing. After the extracted thick mixed oil is filtered, it is put into the mixed oil tank for processing; after the wet meal is emptied, the copper roller on the false bottom rotates with the rotating grid, and gradually flattens along the upward track, and the false bottom is closed tightly, or Go through the gap at the bottom of the grid and go to the initial position of the fixed grid bottom. At this time, it is just aligned with the feeding port and accepts the incoming material; then it enters the next round of continuous operation to form continuous production.
