Abstract
A degradable food container or package is made up of the fibres of plant such as bagasse, reed and masson pine through preheating, thermal grinding to make fibrous pulp, fine grinding, bleaching, mixing with binder, water-proofing and oil-proofing assistant, filler and water, shaping, drying, finishing and sterilization.
Description
But a kind of natural degradation moulding of plant fibres utensils for snack, food and the industrial packaging production method of moulding article.
The present invention relates to a kind of production method of producing degradable utensils for snack, food and industrial packaging goods, belong to the technical field of plant fibre moulding article.
At present, but the production method of the string matter molding utensils for snack of known natural degradation is that the paper pulp that adopts chemical method to produce is raw material.Chinese patent ZL942166515 discloses this method, one of its shortcoming is with chemical agent the big portion of lignin composition that accounts for 20%～30% in the fibrous raw material to be removed in the pulping process, pulping yield 30～45%, the production cost height, compare with at present popular plastic foam mess-tin, its cost exceeds more than one times.And pulping process pollutes big; Two of its shortcoming is to adopt residual in the paper pulp that chemical method produces a spot of chlorinated lignin to be arranged, and this material has proved a kind of carcinogenic substance, and it is unsafe promptly making utensils for snack with this chemical pulp.
But the production method that the purpose of this invention is to provide a kind of string utensils for snack of natural degradation, not only cost is low for it, and resource utilization height, and totally nontoxic are safe in utilization, reach the purpose that substituted for plastic foam snack container is eliminated " white pollution ".
It is fibre stuff that the present invention adopts preheating thermomechanical method to separate timber non-wood materials such as reed, bagasse, masson pine, (non-wood materials such as wood raw material is chipped, bamboo, awns bar prescind raw material through getting the raw materials ready, bagasse removes marrow etc.) after send into feed bin, enter continuously (or intermittently) formula boiling vessel again and carry out The pre-heat treatment.Preheat temperature is 110 ℃～190 ℃, be 5～120 minutes preheating time, do corresponding the adjustment with different raw materials and purposes, under pressure, the material after the preheating is sent into disc mill, the diameter of disc mill can change between φ 300～φ 1500mm with the requirement difference that production capacity reaches slurry, and material grinds pulping in disc mill, and the beating degree of slurry is 20～45 ° of SR, pulping yield can reach 95%, and pulping process pollutes few.
Adopt disc type steel mill or stone mill to finish grind, and make slurry acquisition grinding make fiber have bond strength preferably, the bleaching of slurry can add bleaching agent and auxiliary agent in preheating defibrator process process, bleaching and defibrator process fiber separation are once finished, also can bleach after defibrator process, bleaching agent is a hydrogen peroxide etc. again, and consumption is 1～10% of an over dry slurry, auxiliary agent is with sodium metasilicate etc., and obtaining whiteness is the slurries of 50～70 degree.Also can not bleach and directly use according to the customer requirements fibre stuff, the product of making is exactly a natural colour.
The fiber that above technology is made through washing after, packaged food and utensils for snack are adopted the water that conforms with national drinking water standard; Adopt water for industrial use to be made into certain density slurries to the industrial packaging material, the waterproof and oilproof auxiliary agent and the filler that add the certain proportion sizing material, the waterproof and oilproof auxiliary agent can be silicone based, modified cellulose class, chitin kind and modified starch series etc. and composition thereof and other active principles, and the waterproof and oilproof auxiliary dosage is 0.5～10%.Auxiliary agent must meet the sanitary standard requirement of tableware.
Fibre stuff through preparation carries out moulding under negative pressure in the make-up machine that has the stainless (steel) wire mould, make fiber mould base, the base of making is placed on and dries processing in the continuous dryer, again with the moulding press processing of finalizing the design, perhaps directly base is placed on and carries out dryness finalization in the moulding press and handle after the oven dry.Then, product by trimmer cut edge, embossing, shaping, but handle and operation such as packing is made natural degradation moulding of plant fibres utensils for snack, food and industrial packaging fibre mould goods through check, disinfection by ultraviolet light through the tableware after the typing.
Compare with the ZL942166515 disclosed method, the utensils for snack that adopts method disclosed by the invention to produce, its cost of raw material can reduce more than 50%.
Embodiment 1: bagasse is passed through the boiling vessel boiling, 150 ℃ of temperature, 10 minutes time, with φ 300 defibrator defibrator process pulpings, make 25 ° of SR of beating degree of bagasse slurry, whiteness 45 degree, again with φ 300 disc mills correct grinding, the fiber beating degree is brought up to 30 ° of SR, adopts hydrogen peroxide bleaching to whiteness 65 degree, adds the grease-proof and waterproof auxiliary agent.Be molded on the steel mesh mould with the vacuum forming method, use a pressure sintering compression molding again, 140 ℃ of hot pressing temperatures, 40 seconds time.Make paper pulp and mould fast food lunch-box, its whiteness is 65 degree, pours 100 ℃ of hot water into and does not have the leakage of rushing down half an hour.And three months degradables under field conditions (factors) after using.
Embodiment 2: southern leaf wood is used the technology boiling relative with embodiment 1, with φ 900 defibrator defibrator process pulpings, adopts the technology correct grinding identical with embodiment 1 and bleaches, and compression molding, make the paper mould fast food lunch-box, its whiteness is 65 °, pours 100 ℃ of hot water into and does not have the leakage of rushing down half an hour.And three months degradables under field conditions (factors) after using.
