[0031] The implementation principle of a horizontally rotating continuous extractor in the embodiment of the present application is as follows:

[0032] Taking advantage of the physical property of oils and fats that can be dissolved in organic solvents, the pretreated material or pre-pressed cake is soaked or sprayed with an organic solvent to dissolve the oil in the organic solvent to obtain a mixed oil, which then enters the next process.

[0033] The working process is as follows: the material is evenly added to the material grid 23 through the feed hopper 7 and the material distributor, and a certain material layer height is formed. The driving mechanism 5 drives the rotor mechanism to rotate at a set speed and low speed, pushing the material to the discharge port. In this process, the solvent is sprayed on the material through the spray pipe 10. After the material is sprayed and soaked, the grease in the material is slowly dissolved, precipitated, and dissolved in the solvent, commonly known as mixed oil. The mixed oil is filtered through the sieve plate 2 into the oil storage tank 1 and circulated and sprayed through the circulating pump 13. After the material has been leached for 1-4 hours, the first cylinder 11 at the oil draining station 22 extends and pushes the pressure plate 12 to squeeze the material in the material grid 23, so that the solvent in the material can be squeezed out to ensure that the material is relatively dry, and then enters the discharge trough 101 for discharge, which is convenient for subsequent processing.

Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
