Description
Technical Field
The invention relates to the technical field of packaging paper production, in particular to a production process and production equipment of degradable packaging paper.
Background
With the development of the food industry, the variety of food wrapping paper is increasingly diversified, and common paper for external packing of cake paper, candy paper, facial tissue hanging box, bread paper, biscuit paper box and ice cream is cake paper, candy paper and candy paper.
Patent document (CN 107524044A) discloses a moisture-proof wrapping paper, which is made of modified materials, is safe and nontoxic, has no pollution to the environment, is more suitable for packaging moisture-proof articles, does not absorb water, and has a surface polyethylene film further enhancing the waterproof function of the wrapping paper, so that water does not soak into the wrapping paper when contacting with the wrapping paper; the packing paper has the bacteriostatic action, and when the packing paper is used for packing articles, the articles cannot be corroded by bacteria for a long time, the packing paper also has the antioxidant function, and the packing paper is in contact with air or sunlight for a long time, so that the oxidation phenomenon cannot occur, and the packing paper cannot be oxidized, discolored and the like. However, the packaging paper is not easy to degrade, paraffin is required to be coated on two sides of the film in the production process, a part of paraffin is wasted in the melting process of the existing production equipment, and the coating efficiency of the film is not high.
Disclosure of Invention
The invention aims to provide a production process and production equipment of degradable packaging paper, which solve the following technical problems: (1) konjac glucomannan is used as a main raw material, soy protein isolate and carrageenan are added as auxiliary materials, glycerol is used as a plasticizer, and added slurry is not bleached, so that carcinogens such as dioxin, organic halide and the like are not contained, and the fiber slurry is porous and has thick wall, so that the air permeability and the strength of finished paper can be effectively improved; the degradable food packaging paper is prepared by the processes of sol, mixing, swelling, drying, coating edible paraffin and the like, and has the characteristics of safety, no toxicity, environmental protection and the like; meanwhile, the mechanical strength is obviously improved, the added raw materials are all food grade, the food is not polluted even if the food has a permeation phenomenon, and the paper can be used as inner packaging paper of foods such as ice cream, cakes, fried foods and the like; (2) the production equipment is characterized in that the planetary gear is matched with the central gear in the melting cavity, the stirring roller is used for stirring the paraffin while the stirring frame is used for stirring, the double internal and external stirring enables the melting effect of the paraffin to be better, and meanwhile, the condition that part of the molten paraffin cannot be conveyed downwards on the inner wall of the melting cavity is avoided; (3) this production facility is through offering out the wax mouth on two waxing roller surfaces, and the waxing roller is to membrane surface coating paraffin when satisfying to the membrane transport, and paraffin coating is efficient and the coating is even, smears even processing through even wax tape after paraffin coating simultaneously to collect unnecessary paraffin, make things convenient for the recycle of paraffin.
The purpose of the invention can be realized by the following technical scheme:
a production process of degradable wrapping paper comprises the following steps:
the method comprises the following steps: weighing 4-8 parts of konjac glucomannan, 8-10 parts of carrageenan and 8-10 parts of soybean protein isolate according to parts by weight, dissolving the konjac glucomannan, the carrageenan and the soybean protein isolate in 1L of water, uniformly stirring, standing and swelling for 2-3h to obtain konjac sol;
step two: melting food-grade raw wood pulp and water, and adjusting the pH to 7.5-8.5 by using 0.1mol/L sodium hydroxide to prepare food-grade wood pulp;
step three: adding glycerol which accounts for 0.3-0.5% of the weight of the konjac sol into the konjac sol in the first step to serve as a plasticizer, adding the food-grade wood pulp prepared in the second step in an amount which is 2.5-3.5 times of the weight of the konjac sol, stirring the mixture by using a stirrer at 70-85 ℃ in a water bath, adjusting the viscosity of the sol by using 5-20% of modified starch solution to enable the viscosity to be not less than 600Pa & s, and adjusting the pH of the sol to be 8.0-9.5 by using 0.1mol/L sodium hydroxide or sodium carbonate powder;
step four: ultrasonic degassing at 200-400W by using an ultrasonic degassing machine, rolling and forming to obtain a film when the film is cooled to 45-50 ℃, and drying the film in an oven until the water content is not higher than 8%;
step five: taking out the dried film, cooling at room temperature, pouring paraffin into the film from a paraffin inlet on a melting cavity on production equipment, enabling the paraffin to enter the melting cavity, driving a driving rod to rotate by a first motor, driving a stirring frame to rotate by the driving rod, matching a planetary gear on a stirring roller with a central gear while the stirring frame rotates, rotating the stirring roller on the stirring frame, stirring the paraffin in the melting cavity by the stirring frame and the stirring roller, enabling the molten paraffin to enter a conveying cavity, driving a connecting roller to rotate by a telescopic cylinder matching with a rotating arm, matching the connecting roller with a rotating pull rod, scraping the paraffin on the inner wall of the melting cavity by a scraping blade on a moving strip into the conveying cavity, driving two conveying screws to rotate by a second motor matching with two gears, conveying the paraffin in the conveying cavity into two paraffin coating rollers by two communicating pipes by the two conveying screws, enabling the film on a film roller on a support frame to pass between the two paraffin coating rollers, two wax coating rollers pass through wax outlet and coat paraffin on the upper and lower surface of membrane, and the membrane after the coating is through two even wax areas, and even wax area is smeared the paraffin on membrane surface evenly, and scribble unnecessary paraffin simultaneously and smear on inhaling the wax roller, and the scraper will inhale paraffin on the wax roller and strike off to the collecting vat in, take out the collecting vat from waxing indoorly, can take out unnecessary paraffin, and two even wax areas carry out the membrane from waxing room, then dry the membrane, obtain degradable wrapping paper.
Further, in the second step, the water content of the food-grade raw wood pulp is 15% -20%, and the weight ratio of the raw wood pulp to the water is 1: 8-10, dissolving pulp, wherein the raw wood pulp is unbleached and has a degree of fragmentation of 150-200 meshes, and the length of the contained wood fiber is 2.5-3.0 mm.
