Abstract
The invention provides a method for preparing an environment-friendly snack box. The method comprises the following steps: mixing rice husks, oat straws and maize straws to produce a main ingredient, according to the weight ratio of 1: 0.9-1.2: 0.6 -0.9; mixing rubberlith, starch, alum and olefin to produce an auxiliary ingredient according to the weight ratio of 1: 1.2-1.6 : 0.2-0.4 : 0.1-0.3; mixing the main ingredient and the auxiliary ingredient according to the weight ratio of 3 to between 2 and 2.5; evenly stirring the mixed ingredients by hot water at 90 DEG C to press a rough blank of the snack box; and producing a finished product of the snack box through surface sizing and roasting. The snack box produced by the production method can be completely and naturally degraded without polluting the environment; moreover, the snack box has wide source of raw materials, simple production process, and lower cost than a plastic foam snack box.
Description
Technical field
The present invention relates to the Food Packaging technology field, be specifically related to the preparation method of the environment friendly fast food box of a kind of disposable use, non-environmental-pollution.
Background technology
Along with China's development of economic construction, people's rhythm of life is constantly accelerated, and fast food is widely accepted, and the use amount of disposable fast food packing box also grows with each passing day.At present the disposable snack box that uses of China mostly is to adopt vinyon blowing (foaming) to make, and this tableware has cheap advantage, but also is repeated utilization easily, and main is can't natural degradation, has brought serious pollution to ecological environment.This pollution effect is permanent, is difficult to eliminate, and has become serious problems of China environmental protection.
In recent years, the degradeable snack box product that substitutes the polyethylene foam mess-tin emerged in an endless stream, and mainly contained paper mould cutlery box, cardboard compacting cutlery box, stalk husk tableware, optically and biologically degrading tableware, starch and closed products such as moulding the plastic uptake tableware.
Wherein the cost of paper mould cutlery box and cardboard compacting cutlery box is higher, paper pulp large usage quantity especially, and the heavy damage forest reserves, and can't the reclaiming utilization; Be added with plastic additive and chemical synthesis auxiliary agent more than 40% in the stalk husk cutlery box, can not all degrade; Optically and biologically degrading tableware and starch close that to mould plastic uptake tableware investment of production equipment big, manufacture craft process complexity, and additive costs an arm and a leg, and is difficult for promoting the use of.
Utilize natural degradable macromolecular materials such as protein, starch, crude fibre to produce the environmental-protection quick cutlery box and have good market prospects.But, with string such as straw, straw, reed or other grass family wild plant is that the common problem that degradable snack box that major ingredient processes exists is, fiber after string is pulverized shortens, and need add more colloid during production, as pectic substance select improper, ratio is improper, can cause the bonding force between string and the colloid not strong, the stretching resistance of mess-tin is poor, and is easily cracked, and gum level is when too high, mess-tin is felt like jelly, do not endure with all one's will easy deformation.
Summary of the invention
It is reliable to the purpose of this invention is to provide a kind of health, free from environmental pollution, all the preparation method of the environment friendly fast food box of natural degradation.
The preparation method of environment friendly fast food box of the present invention is to be major ingredient with husk, oat bar, cornstalk, and lithopone, starch, alum, paraffin are auxiliary material, mixes the compacting mess-tin, the steps include:
A) husk, oat bar, milled powders of cornstalk are broken into 150～200 purpose fine powders, are mixed and made into major ingredient according to the weight ratio of 1:0.9～1.2:0.6～0.9;
B) according to starch: the weight ratio of lithopone: alum: paraffin=1:1.2～1.6:0.2～0.4:0.1～0.3 is mixed and is formed auxiliary material;
C) according to the weight ratio of 3:2～2.5 with major ingredient with after auxiliary material mixes, add 90 ℃ of hot water that account for 1～2 times of major ingredient and auxiliary material gross weight again, mixing and stirring is cut into the small powder of 70～80g;
D) small powder is added mold in the moulding machine, cast mess-tin base just;
E) surface coating of base at the beginning of mess-tin;
F) with mess-tin behind the gluing just base make the mess-tin finished product in 90 ℃ of baking 5～6min.
The present invention needs to add certain auxiliary material when the preparation mess-tin.Wherein, lithopone mainly is to use as forming agent, and its consumption generally is controlled at 20～30% of batching gross mass.If the forming agent consumption is too much, the mess-tin embrittlement of then producing and heavy; If the forming agent consumption is very few, then poor, the light transmittance height of the compression strength of mess-tin, Waterproofing/oilproofing not.In addition, starch uses mainly as binder, can use cornstarch or farina, and its consumption also can not be too much, otherwise can influence the rheological property and the foam performance of mess-tin.In other auxiliary materials, alum is coagulant, and paraffin uses as waterproofing agent.
Auxiliary material to mess-tin finished product quality influence maximum is a forming agent, if the fineness of forming agent is little, whiteness is high, the mess-tin of then producing is pure white, be rich in gloss.General fineness with forming agent lithopone is advisable more than being controlled at 200 orders.
During with major ingredient and auxiliary material mix, must use the hot water more than 90 ℃, and fully mix and stir 20～30min.If water temperature is lower than 90 ℃, will not bring into play separately effect owing to major ingredient and auxiliary material can not combine together.
After blank finishes, should immediately small powder be added mold in the moulding machine.Should be noted that mold temperature and time GPRS are proper, if mold temperature is low excessively, the time is too short, the edge of mess-tin drying and moulding then, and the bottom surface also has little time reaction, can cause the disengaging of mess-tin edge and bottom surface; If mold temperature is too high, the mold overlong time then can be with the roasting paste of mess-tin.Usually, should control mold temperature is 200 ℃, and the mold time, 60～70s was advisable.
Mess-tin just the purpose of base surface coating be waterproof, grease proofing effect, particularly under the situation that boiling water brews, require rubberised layer should be able to anti-continuously 100 ℃ of water temperature 2h about.Simultaneously, after mess-tin abandoned modification, rubberised layer can break away from mess-tin soon, and mess-tin is degraded.Gluing should carry out after mess-tin base cooling just, otherwise the crack that can when oven dry, cause rubberised layer.General employing polyethylene glue or lucite glue are as the rubberized material on mess-tin surface.
Adopt production method of the present invention to produce mess-tin, raw material sources are extensive, and production process is easy, does not need complex apparatus and technology, and cost is also cheaper than plastic foam mess-tin.
The mess-tin compressive resistance height, the stretching resistance that adopt production method of the present invention to produce are good, not easily broken, have toughness preferably, and mess-tin is stiffening does not feel like jelly, and splendid attire food is indeformable.
Mess-tin of the present invention is natural degradation all, and is free from environmental pollution, solved discarded mess-tin problem of environment pollution caused, the favorable environment protection.
The specific embodiment
With forming agent lithopone 30kg, binder farina 20kg, coagulant alum 5kg, waterproofing agent paraffin 4kg mixing and stirring, make auxiliary material.
Get the husk 10kg, oat bar 10kg, the milled powders of cornstalk 8kg that are ground into 200 order fine powders, drop in the mixer with above-mentioned auxiliary material 20kg, add 50kg90 ℃ hot water, stirring 20min makes and mixes.Be cut into small powder by each mess-tin 70g then.
Small powder is added in the moulding machine,, casts mess-tin base just in 200 ℃ of temperature bottom mold 60～70s, treat base cooling just after, with polyethylene glue at the first surface coating of base of mess-tin, at last with dryer at 90 ℃ of baking 5～6min, make the mess-tin finished product.
