The invention relates to the technical field of food processing, in particular to a filtering device for efficient deep-frying equipment. The filtering device comprises a plurality of filtering containers in parallel, a filtering device arranged in each filtering container, a vacuum pump and a recovery container, wherein each filtering device comprises a multi-stage filtering net, and the filtering containers in parallel are connected with an oil inlet pipeline, an oil outlet pipeline, a recovery pipeline and a vacuumizing pipeline. The multi-stage filtering net can trap food oddments mixed todeep-frying oil in different filtering nets, the filtering capacity is improved, besides, the filtering nets can also be prevented from being blocked, after filtration is completed, the deep-frying oil adhered to the food oddments is converged into the recovery container under the action of pressure differences, and besides, the filtering nets can be cleaned to a certain extent. The filtering device is simple in structure, and can effectively prevent the filtering nets from being blocked. Besides, the labor force and the time cost for cleaning are greatly reduced, high recovery rate of the deep-frying oil can be realized, and fine production is facilitated.
