Problems solved by technology

[0003] Most of the current treatment methods for waste cooking oil are to directly take out the impurities in the oil and use them again, but they are still not thoroughly treated, which will affect the use and still cause certain harm to the human body. Most of the treatments are not completely degreasing the oil in the oil, and the effect is poor, which affects the treatment effect

Abstract

The invention discloses a method for degreasing and purifying waste edible oil, and relates to the technical field of waste edible oil treatment. The method mainly comprises the following steps: collecting, removing impurities, carrying out alkali washing condensation, standing for layering, decolorizing, deodorizing, filtering, recovering grease, distilling, uniformly mixing H-type modified polypropylene fibers, ferroferric oxide powder, ground phosphate rock and polyferric sulfate, and filling into a reaction tank to form a primary filter layer, the weight ratio of the H-type modified polypropylene fiber to the ferroferric oxide powder to the polyferric sulfate is 8: 2: 1: 1. According to the method disclosed by the invention, the waste oil becomes clear refined oil through decoloration, odor in the waste oil is effectively removed through deodorization, and impurities and other harmful substances in the waste oil are removed through impurity removal, filtration and other steps, so that the value of the oil is increased; the feed oil use standard is reached.

Description

technical field [0001] The invention belongs to the technical field of waste edible oil treatment, in particular to a method for degreasing and purifying waste edible oil. Background technique [0002] With the rapid development of our country's economy, the catering industry and tourism industry have also developed. The related problems are that the amount of waste cooking oil in the catering industry such as hotels and hotels is also increasing.
