Purpose Grease leaching is the most important process in the oil leaching process, and the leaching device is one of the key equipment in the grease leaching process.The drag chain leaching device uses the drag chain to push the material to move on the bottom of the grid plate. After spraying, soaking, draining and other processes, the grease and solvent are separated from the material under certain time and temperature conditions.The drag chain leaching device is widely used for the leaching of various oily materials such as soybeans, rapeseed, cottonseed, peanuts, etc., and can also be used as pigment extraction equipment for various pigment raw materials such as chili peppers and chrysanthemums.
Performance characteristics The equipment adopts full automatic control of the main power, the spindle can realize stepless variable speed rotation, the material layer is low, the soaking is sufficient, and the material is flipped once during the leaching process, which is conducive to thorough leaching.It has the characteristics of stable and reliable work, small footprint, easy installation and layout, and good leaching effect.
Working Principle
The material is fed into the housing of the leaching device by the feeding device, and the material is pushed to move on the bottom of the grid plate through the drag chain. A uniform material layer of a certain thickness is formed under the action of the homogenization of the raking device. The solvent is evenly sprayed on the material by the spray system, and the oil components inside the material are leached and separated by the principle of extraction. Through the continuous spraying and circulation of mixed oils of different concentrations, under certain soaking time and temperature conditions, the grease in the material is thoroughly leached and separated, and then the mixed oil is withdrawn from the oil bucket of the leaching device by a mixing oil pump, and the material enters the discharge system through the draining process. , The meal is fed into the next process by the discharge buried scraper.
