Problems solved by technology

Moreover, food residues in oil will undergo oxidation, hydrolysis, polymerization and other reactions after repeated high-temperature frying, which will increase the acid value and peroxide value of edible frying oil, causing oil deterioration
Such processed food will also cause harm to the health of the eater. In addition, the long-term high temperature will cause the decomposition of polymer compounds and increase the acidity of the oil, which limits the shelf life of fried food. Therefore, high-temperature edible oil filter paper must be used for filtration.

Embodiment 1

[0019] Example 1 90 parts of Tencel fiber with a fiber fineness of 1.1 dtex and a fiber length of 7 mm and 10 parts of water-soluble PVA fiber were broken into single fibers with a beater, and 0.1 part of anionic polyacrylamide (PAM) was added for dispersion After mixing, add water to prepare a slurry with a concentration of 0.2%, and form it on an inclined screen or a side-flow round screen. The formed wet paper sheet uses 6 parts of polyvinyl alcohol and sodium carboxymethyl cellulose (CMC) as a binder. :1. Prepare 3% concentration for surface sizing, then dry, coil, and cut into products. The main technical indicators of finished paper are: quantitative 23.3g / m 2 , Thickness 0.082 mm, longitudinal tensile strength 0.88kN / m, transverse tensile strength 0.47kN / m, wet longitudinal tensile strength 0.21kN / m, air permeability 1825L / m 2 ·S. (The parts mentioned in this embodiment refer to parts by weight, and the following embodiments are the same).

Embodiment 2

[0021] Example 2 After mixing 40 parts of viscose fiber with a fiber fineness of 5.0 dtex and a fiber length of 3 mm, 45 parts of a vinylon fiber with a fiber fineness of 5.0 dtex and a fiber length of 3 mm and 15 parts of low-melting polyester fiber were mixed, Disintegrate into a single fiber with a hydraulic pulper, add 5.0 parts of polyoxyethylene (PEO) dispersant, add water to prepare a slurry with a concentration of 0.3%, and shape it on an inclined net or a side-flow circular net. The paper sheet is surface sized with 10 parts of 2% surface sizing starch, dried, rolled, and cut into products. The main technical indicators of finished paper are: quantitative 23.2g / m 2 , Thickness 0.080mm, longitudinal tensile strength 1.53kN / m, transverse tensile strength 0.56kN / m, wet longitudinal tensile strength 0.36kN / m, air permeability 1284L / m 2 ·S.

Embodiment 3

[0022] Example 3 After mixing 50 parts of viscose fiber with a fiber fineness of 2.5 dtex and a fiber length of 5 mm, 45 parts of a tencel fiber with a fiber fineness of 4 dtex and a fiber length of 5 mm, and 5 parts of low-melting polyester fiber, Use a beating machine to dissolve into single fibers, add 1.5 parts of polyoxyethylene (PEO) dispersant, add water to prepare a slurry with a concentration of 0.2%, and form it on an inclined wire or a side-flow circular wire to form a wet paper sheet Use 3 parts of 4% polyvinyl alcohol for surface sizing, dry, coil, and cut into products. The main technical indicators of finished paper are: quantitative 24.4g / m 2 , Thickness 0.084mm, longitudinal tensile strength 1.13kN / m, transverse tensile strength 0.44kN / m, wet longitudinal tensile strength 0.26kN / m, air permeability 1734L / m 2 ·S.

Abstract

The invention relates to a high-temperature edible oil filter paper and a manufacturing method thereof, belonging to the technical field of paper making. The manufacturing method comprises the following steps: adding a fibrous adhesive to enhance chemical fibers acting as main raw materials, pulping to defiber the chemical fibers and the fibrous adhesive, adding a certain amount of dispersant, molding with an inclined sieve or a lateral flow type cylinder sieve, applying a liquid adhesive to the surface for enhancement, drying, and cutting to obtain the filter paper capable of being used continuously. The manufacturing method can also comprise the following steps: adding a certain number of plant fibers to the chemical fiber materials, and drying without previously applying a liquid adhesive to the surface for enhancement, thus obtaining the filter paper capable of being used intermittently. Compared with the prior art, the high-temperature edible oil filter paper manufactured by the invention can be continuously or intermittently used, has favorable dry / wet strength, can resist high oil temperature of 180-200 DEG C and has the advantages of high paper uniformity and the like, thereby having fine application prospects.

Description

Technical field [0001] The invention belongs to the technical field of papermaking, and specifically relates to a high-temperature edible oil filter paper with good dry and wet strength, oil temperature resistance of 180-200 DEG C, and uniform paper, and a manufacturing method thereof. Background technique [0002] With the rapid economic development and the increasing living standards of the people, food processing is no longer limited to family cooking, and the wave of corporate food production has swept the world. In the food processing industry, fast food and fast-food fried food have the fastest growth rate, especially Western fast food led by McDonald's and KFC, and Chinese noodle fast food represented by Master Kong and Tongyi. These fast foods use edible oil in large quantities and are repeatedly used. Food slag will inevitably be produced during the frying process. Therefore, the edible oil must be precipitated and filtered after being used for a period of time. Moreove...
