Abstract
A kind of disposable snack box and sanitary chopsticks is made up of rice or wheat straws through drying, breaking, mixing with the aqueous solution of polyvinyl alcohol, injection moulding, adhering the box with a pair of chopsticks, and baking. Its advantages are simple technology and no environmental pollution.
Description
The present invention relates to the production method of disposable snack box or hygienic chopsticks.
Existing disposable snack box is made by plastic foam material or paper material and starch material, and above-mentioned material is made disposable snack box, and there are the following problems: the former is difficult for degraded, causes the white pollution to environment; Though the latter makes moderate progress aspect degraded, consume a large amount of forest tree resources and grain resource, and the cost of manufacture height, increased the weight of consumer's burden.For disposable sanitary chopsticks, wooden by bamboo entirely at present, China is annual owing to use this hygienic chopsticks will consume the forest tree resource how many public affairs are inclined, heavy damage our mankind ecological environments of depending on for existence.
The objective of the invention is and to disclose the production method that a kind of raw materials for production are extensively cheap, production process is simple and convenient, the production product can not pollute with the back reusable edible to the public with straw or straw production disposable snack box or hygienic chopsticks.
Production method of the present invention contains siccative, pulverizing, system mucus, extrusion modling, pairing and baking operation fully, it is characterized in that:
1, in being equipped with the siccative operation, not carrying out dryness in the sun or (dry or toast with other method with totally having the straw that goes rotten or wheat seeds ...) make its drying;
2, in pulverizing process, the straw of drying or straw are pulverized the bean vermicelli shape fines of grow up 0.5～2 millimeter of 3～6 millimeter, diameter with size reduction machinery;
3, in system mucus operation, the PEF alcohol and water is joined in the heating container by 1: 3～4 weight ratio, also insulation is about 90 ℃ in heating, and stirring is dissolved polyvinyl alcohol fully, makes viscous liquid;
4, in the extrusion modling operation, polyvinyl alcohol mucus that dissolving is good and the straw that crushes or straw fines join in the extruder of helical axis simultaneously by 1: 5～6 weight ratio, go in disposable snack box or the hygienic chopsticks mould by the extruder squeeze note again, make at the bottom of the disposable snack box box and the first first base of single chopsticks of base or hygienic chopsticks of single box of lid;
5, in the pairing operation, with at the bottom of the disposable snack box box and the single box of the pairing of lid just base or hygienic chopsticks the single chopsticks of pairing just base compose and lay out at one, and its overlap joint is bonding with polyvinyl alcohol solution or other adhesive solutions;
6, in baking operation, the first base of disposable snack box that pairing is bonding or hygienic chopsticks is sent in the drying room and is dried, and takes out cold and dries in the air, and is finished product.
In order to improve the outward appearance of this disposable snack box or hygienic chopsticks, in the extrusion modling operation, when producing, then in mould, overlap one earlier and decorate pattern for disposable snack box, extruding material in the pattern in the mould makes the moulding outer one deck facing paper of pasting of base just again; When producing for disposable sanitary chopsticks, then making in mould does not earlier have outer paster base just, after the demoulding immediately on first base outside subsides one deck facing paper.
Useful effectiveness of the present invention is as follows: 1, its raw materials for production are common straw and straw, and it is very extensive to originate, and simultaneously they are for the discarded object of agricultural production, and are with low cost; 2, production process is easy, does not need complex apparatus and technology, is easy to go into operation; 3, the product of Sheng Chaning with after can collect heating and produce as raw material circulation again, promptly saved raw material, more solved the problem of environmental pollution that product abandonment brings, favorable environment protection.
Embodiment one: the production method of producing disposable snack box with straw
1, will totally not have mildew and rot straw (preferably remove the standing grain leaf earlier, only stay the rice bar) dryness in the sun under the sun, remove contained most of moisture content;
2, earlier dry straw is cut into 3～6 millimeters short grass material with chaffcutter, with pulverizer the short grass material being broken into diameter again is 0.5～2 millimeter bean vermicelli shape fines;
3, the PEF alcohol and water is poured in the stainless steel cask by 1: 4 part by weight, be heated to about 90 ℃, and stir, polyvinyl alcohol is dissolved fully, make viscous liquid with agitator with water heater;
4, polyvinyl alcohol being dissolved mucus joins in the extruder of helical axis with the weight ratio of the straw fines that crushes by 1: 6, its extruding force is about 50 kg/cm, go in the disposable snack box mould by the extruder squeeze note again, make at the bottom of the disposable snack box box and the first base of single box of lid; In order to improve the outward appearance of mess-tin, (this decoration pattern can be simple blank sheet of paper sample can to pack into a decoration pattern earlier in mould, also can be the decoration pattern of band color, band pattern or band literal), and then extruding material in the pattern in the mould, make the moulding outer one deck facing paper of pasting of base just;
5, with at the bottom of the box and lid two single boxes come one, and its scrap (bridge) is bonding, and make its curing with hot blast with polyvinyl alcohol mucus; Or when extrusion modling, at one its both side is linked to each other with beginning to rehearse with the mould of lid at the bottom of its box, so just in the extrusion modling process, also just finished pairing;
6, with the disposable snack box of pairing just base send in the drying room and dry, take out cold and dry in the air, be finished product.Embodiment two: the production method of producing disposable sanitary chopsticks with straw
1, will totally not have mildew and rot straw dryness in the sun under the sun, but can not be dry excessively because straw too dry friableness when pulverizing can not keep elongated filament;
2, with chaffcutter straw is cut into the short grass material of 3 millimeters long, again with pulverizer with its be broken into diameter be 0.2 millimeter bean vermicelli shape fines; Or directly the straw that dries is broken into the bean vermicelli shape fines that diameter is 0.2 millimeter with pulverizer;
3, the PEF alcohol and water is poured in the stainless steel cask in 1: 3 ratio, be heated to about 90 ℃, and stir, polyvinyl alcohol is dissolved fully, make viscous liquid with agitator with water heater;
4, polyvinyl alcohol being dissolved mucus joins in the extruder of screw shaft with the weight ratio of the straw fines that crushes by 1: 6, extruder pressure is about 50 kg/cm, fast by the extruder squeeze note again by the shaping mould of the disposable sanitary chopsticks of a honeycomb coaly, making diameter is the strip blank of 2.5～3 millimeter, cuts off then to be base just; Or go into fixed length by the extruder squeeze note and decide to make the first base of hygienic chopsticks list chopsticks in the disposable sanitary chopsticks mould of diameter, for attractive in appearance, hygienic chopsticks list chopsticks wrapped immediately stick one deck facing paper (being preferably blank sheet of paper) again;
5, single chopsticks the upper half or full chopsticks being coated with one deck adhesive varnish (polyamine fat varnish) outward, that two single chopsticks the upper halfs are bonded into is a pair of, and the hygienic chopsticks that must match are base (pairing also can be carried out after oven dry is finished again) just;
6, the first base of the hygienic chopsticks of pairing is sent into drying room and dry, take out cold and dry in the air, be finished product.
