Embodiment 1

[0033] A kind of production technology of greaseproof paper, it comprises the following steps:

[0034] ⑴ Beating:

[0035] ①Put the cloth needle pulp board and non-fluorescent bamboo pulp board with mass percentages of 25% and 75% respectively into the hydraulic pulper and add water to disintegrate, control the pulp water mass concentration to 4.0%, and transfer to the pulp storage tank;

[0036] ②After disintegration, the pulp water is beaten with a double disc mill in series, and the return valve is opened to circulate the pulp water. The model of the grinding disc is type 4. The grinding teeth of the grinding disc are arranged in an S shape, with a tooth width of 2.0mm, a tooth groove width of 1.7mm, and a tooth depth 3.4mm ， Carry out a percussion, semi-viscous beating. When the slurry water reaches the percussion degree: 76 o SR, wet weight: 4.0g, concentration: when it is 4.0%, it is converted to the slurry tank;

[0037] ⑵Pulp mixing: the slurry water is transferre...

Embodiment 2

[0055] A kind of production technology of greaseproof paper, it comprises the following steps:

[0056] ⑴ Beating:

[0057] ①Put the cloth needle pulp board and non-fluorescent bamboo pulp board with mass percentages of 30% and 70% respectively into the hydraulic pulper and add water to disintegrate, control the pulp water mass concentration to 4.25%, and transfer to the pulp storage tank;

[0058]② After disintegration, the pulp water is beaten with a double-disc mill in series, and the return valve is opened to circulate the pulp water. The model of the grinding disc is type 4. The grinding teeth of the grinding disc are arranged in an S shape, with a tooth width of 2.2mm, a tooth groove width of 1.9mm, and a tooth depth 3.6mm ， Carry out a percussion, semi-viscous beating. When the slurry water reaches the percussion degree: 77 o SR, wet weight: 4.25g, concentration: when 4.25%, it is converted to the slurry tank;

[0059] ⑵Pulp mixing: the slurry water is transferred f...

Embodiment 3

[0078] A kind of production technology of greaseproof paper, it comprises the following steps:

[0079] ⑴ Beating:

[0080] ①Put the cloth needle pulp board and non-fluorescent bamboo pulp board with mass percentages of 35% and 75% respectively into the hydraulic pulper and add water to disintegrate, control the pulp water mass concentration to 4.5%, and transfer to the pulp storage tank;

[0081] ②After disintegration, the pulp water is beaten with a double disc mill in series, and the return valve is opened to circulate the pulp water. 3.8mm ， Carry out a percussion, semi-viscous beating.

Abstract

The invention discloses a production process of greaseproof paper. The production process includes: taking a needle pulp board and a nonfluorescent bamboo pulp board, pulping, preparing pulp, slushing, applying glue, papermaking on a screen, pressing, pre-drying, surface-gluing, post-drying, press-polishing, controlling quality, coiling, and packing to obtain the finished paper, wherein weight percent of the needle pulp board and the nonfluorescent bamboo pulp board is 30+ / -5% and 70+ / -5%, preferred ratio of the needle pulp board to the nonfluorescent bamboo pulp board is 30%:70%, speed of papermaking on the screen is 90m / min, mass concentration of the screen is 0.45-0.55%, preferred pulping grinding teeth are 2.2mm in width, 1.9mm in teeth channel width, and 3.6mm in teeth depth, preferred press polishing machine is a four-roller soft press polishing machine with double pressing areas, preferred raw material is food grade, and preferred pipeline is made of 304L type stainless steel. By the production process, potential safety hazard due to larger amount of oil-proofing agent used in the greaseproof paper in traditional production process is avoided, and amount of the oil-proofing agent used in the greaseproof paper is reduced greatly. The greaseproof paper produced by the process has fine gloss, tightness, and oil resistance, and reaches food grade.

Description

technical field [0001] The invention relates to a production process of greaseproof paper. Background technique [0002] Oil-proof paper is commonly used in food production and packaging. Most of the existing oil-proof paper manufactures completely use oil-proof agents to achieve the oil-proof effect, and most of the raw materials used are non-food grade, such as 200780033946.6 and 200410071449.3. Paper products are coated or sizing to achieve oil-proof effect, and 201120285336.9 and 200820162733.5 are coated with silicone oil to prevent oil. Therefore, the greaseproof paper produced is difficult to meet the food use standard, which brings hidden dangers to food safety. Contents of the invention [0003] The object of the present invention is to provide a production process of greaseproof paper, which overcomes the potential safety hazards that may be caused by using a large amount of oilproof agents in the greaseproof paper, and improves the safety of the greaseproof pap...
