The Production Process Of Food Grade Air Fryer Paper

The production process of food grade air fryer paper generally includes the following main steps:
Raw material selection
Wood pulp: High quality virgin wood pulp, such as coniferous wood pulp and broad-leaved wood pulp, is usually selected. Needle wood pulp has long fibers, high strength, and can endow paper with good toughness and tensile strength; Hardwood pulp fibers are short and have good interweaving properties, which can make the surface of paper smoother. The two are mixed in a certain proportion to achieve ideal physical properties.
Additives: Adding food grade additives, such as wet strength agents, can improve the strength of paper in humid environments; Retention aids can help fibers and fillers stay better in the paper, improving the quality and stability of the paper; There are also some oil resistant and waterproof agents that give paper good oil and water resistance, ensuring that it will not be damaged or deformed due to the oil and moisture of food in the high temperature environment of an air fryer.
pulping
Crushing: Cut the logs into suitable wood pieces and send them to a pulper. Add an appropriate amount of water to crush the wood pieces into fibers and make coarse pulp.
Screening and purification: Coarse pulp is filtered through screening equipment to remove impurities such as sawdust, bark, etc. Then, purification treatment is carried out to further remove small impurities such as sand particles and metals, ensuring the purity of the pulp.
Beating: The purified pulp is subjected to pulping treatment, where the fibers are subjected to forces such as shear and friction through mechanical action, resulting in fiber separation and pulverization. This increases the specific surface area and interlacing ability of the fibers, thereby improving the strength and flexibility of the paper.
papermaking
Ingredients: According to the performance requirements of the product, different types of pulp and additives are mixed evenly in a certain proportion to prepare a pulp suitable for producing air fryer paper.
Copying: The prepared pulp is fed into a paper machine and evenly distributed on the papermaking belt through a flow box. Under the action of gravity and vacuum suction, the moisture is quickly filtered out, and the fibers gradually interweave to form wet paper sheets.
Squeezing: Wet paper passes through the pressing section and further squeezes out moisture through mechanical pressure, improving the dryness and tightness of the paper and enhancing its strength.
Drying: After pressing, the paper enters the drying section and is dried using steam heated drying cylinders or hot air to remove residual moisture from the paper, achieving the specified moisture content and further stabilizing and improving the physical properties of the paper.
surface treatment
Coating: In order to further improve the oil resistance, waterproofing, and anti sticking properties of air fryer paper, coating treatment is usually carried out on the surface of the paper. Coating liquid is generally composed of food grade polymer materials, oil resistant agents, waterproofing agents, etc., and is uniformly coated on the surface of paper through coating equipment to form a thin layer of coating.
Polishing: After coating, the paper is subjected to a calendering machine, which uses mechanical pressure and temperature to make the surface of the paper smoother and more even, improving the glossiness and printing adaptability of the paper. At the same time, it can also make the coating bond more tightly with the paper, enhancing the stability and durability of the coating.
Split packaging
Slitting: Cut the surface treated large roll of paper into various sizes suitable for use in air fryers according to the specified size and specifications.
Packaging: After quality inspection, the cut air fryer paper is packaged in a certain quantity, usually using packaging materials such as plastic film or paper boxes, to prevent contamination and damage to the paper during transportation and storage.
Throughout the entire production process, manufacturers need to strictly comply with food related safety standards and hygiene regulations to ensure the quality and safety of air fryer paper, so that it can be safely used for food cooking.
