Abstract

The invention discloses a production technique for edible oil filter paper, which is characterized in that bleached softwood pulp is taken as a main raw material; and the mercerization processing for the raw material is carried out by adopting alkali liquor. The technique also comprises a winkling processing, i.e. a scraper is contacted with paper sheets, thus chatter marks are generated on the paper sheets because the paper sheets is provided with different speed at the time of passing through the squeezed part and the dried part and the scraper is arranged on the squeezed part; the chatter marks can increase the gap and the filter area among a plurality of layers of filter papers, reduces the filter resistance of a plurality of layers of filter papers, strengthens the air permeability and simultaneously enhances the broken strength resistance of the filter paper; the production cost of the technique is low; and the filter papers produced by the invention are only YMB **** / ton compared with the price of the same type of the existing import filter papers (about YMB *** / ton).

Description

technical field [0001] The invention relates to a production process of food oil filter paper, belonging to the technical field of special paper production. Background technique [0002] As our country enters the stage of building a well-off society in an all-round way, people's living standards continue to improve, and there is a large demand for green and environmentally friendly food, especially high-grade edible oil that is clear, fragrant and pure is more and more popular. During the production of edible oils, the degree of purification in the filtration stage is crucial. [0003] In the traditional process, filter cloth, chemical fiber filter paper and palm oil filter paper are usually used to filter edible oil. However, such traditional filter materials are neither hygienic nor environmentally friendly, and their filtration accuracy and efficiency are relatively low, but the cost is high. [0004] In the field of fuel oil purification, filter paper is commonly used ...
