Production process of degradable packaging paper and production equipment

Abstract

The invention discloses a production process of degradable packaging paper and production equipment. According to the production process, konjac glucomannan is used as a main raw material, soy isolateprotein and carrageenan are added as auxiliary materials, glycerin is used as a plasticizer, the added pulp is not bleached, therefore, cancerogens such as dioxin and organic halide do not exist, andthe fiber pulp is porous and is thick in the wall, so that the air permeability and strength of paper can be effectively increased; the degradable food packaging paper is prepared in the steps of dissolving in sol, mixing, swelling, drying and applying edible paraffin and has the characteristics of safety, no toxicity or harmlessness, environmental friendliness and the like; and additionally, themechanical strength is obviously increased, all of the added raw materials are food grade, food cannot be contaminated even if the osmotic phenomenon exists, and the degradable food packaging paper can be used as the inner packaging paper for ice cream, cakes, fried food and the like.

Description

technical field [0001] The invention relates to the technical field of packaging paper production, in particular to a production process and production equipment for degradable packaging paper. Background technique [0002] With the development of the food industry, there are more and more types of food packaging paper. The more common ones are cake paper, candy paper, noodle cartons, bread paper, biscuit cartons, and ice cream outer packaging paper. [0003] The patent document (CN107524044A) discloses a moisture-proof wrapping paper. The material selected for the wrapping paper is safe and non-toxic after modification, and has no pollution to the environment. It is more suitable for packaging moisture-proof articles. Further strengthen the waterproof function of the wrapping paper. When water touches the wrapping paper, the water will not soak into the paper; The paper will not be oxidized when it is exposed to air or sunlight for a long time, so the wrapping paper will n...

Problems solved by technology

[0004] The object of the present invention is to provide a kind of production technology and production equipment of degradable wrapping paper, solve the following technical problems: (1) take konjac glucomannan as main raw material, add soybean protein isolate and carrageenan as auxiliary materials, and use glycerin as Plasticizer, the pulp added has not been bleached, so it does not contain carcinogens such as dioxins and organic halides, and this fiber pulp is porous and thick, which can effectively improve the air permeability and strength of the paper; after sol, Mixing, swelling, drying, and smearing edible paraffin to make degradable food packaging paper, which is safe, non-toxic, and environmentally friendly; at the same time, the mechanical strength is significantly improved, and all the raw materials added are food grade. , even if there is infiltration, it will not pollute the food, and can be used as the inner wrapping paper of ice cream, cake, fried food and other foods; (2) The production equipment cooperates with the planetary gear and the central gear in the melting chamber, and the stirring box While stirring, the stirring roller also stirs the paraffin. The double internal and external stirring makes the melting effect of the paraffin better, and at the same time avoids the situation that the melted part of the paraffin cannot be transported downward on the inner wall of the melting chamber; (3) The production equipment passes through two A wax outlet is opened on the surface of each waxing roller, and the waxing roller satisfies the film conveyance while coating the paraffin wax on the film surface. The paraffin coating efficiency is high and the coating is uniform. processing, and the excess paraffin is collected to facilitate the recycling of paraffin
