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

[0020] Example 1 90 parts of tencel fibers with a fiber fineness of 1.1dtex and a fiber length of 7 mm and 10 parts of water-soluble PVA fibers were disintegrated into single fibers with a beater, and 0.1 parts of anionic polyacrylamide (PAM) was added to disperse After adding water to prepare a slurry with a concentration of 0.2%, it is molded on an inclined wire or a side-flow circular wire. The formed wet paper is filled with 6 parts of polyvinyl alcohol and sodium carboxymethyl cellulose (CMC) in 1 : 1 Prepare a concentration of 3% for surface sizing, and make products after drying, coiling, and slitting. 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 described in this embodiment refer to parts by weight, and the following examples are the same).

Embodiment 2

[0022] Example 2 After 40 parts of viscose fibers with a fiber fineness of 5.0 dtex and a fiber length of 3 mm, 45 parts of vinylon fibers with a fiber fineness of 5.0 dtex and a fiber length of 3 mm and 15 parts of low-melting point polyester fibers were mixed, Disintegrate into single fibers 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 screen or a side-flow circular screen. The formed wet The paper sheet is surface sized with 10 parts of 2% surface sizing starch, dried, coiled and slit to make the product. 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

[0023] Example 3 After mixing 50 parts of viscose fibers with a fiber fineness of 2.5 dtex and a fiber length of 5 mm, 45 parts of tencel fibers with a fiber fineness of 4 dtex and a fiber length of 5 mm and 5 parts of low-melting polyester fibers, Use a beater to disintegrate 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, and make products after drying, coiling and slitting. 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

[0001] technical field [0002] The invention belongs to the technical field of papermaking, and in particular relates to a high-temperature edible oil filter paper with good dry and wet strength, oil temperature resistance of 180-200°C and uniform paper and a manufacturing method thereof. Background technique [0003] With the rapid development of the economy and the improvement of people's living standards, the processing of food is no longer limited to home cooking, and the wave of enterprise production of food has swept the world. In the food processing industry, fast food and fast-food fried food have the fastest growth rate, especially Western-style fast food led by McDonald's and KFC, and Chinese-style noodle fast food represented by Master Kong and Uni-President. These fast foods use a large amount of edible oil, and are repeatedly used, and food residues will inevitably be produced during the frying process, so the edible oil must be precipitated and filtered after ...
