Abstract
The expendable dining utensils such as box, cup, etc. is made up of fruit shell, plant stem or stalk, saw dust, starch, calcium carbonate and water through mixing, loading mixture in mould cavity, vibration, pressurizing, closing mould, demoulding, keeping pressure, spraying whitening coating of polyvinyl alcohol, spraying water-proof coating of polystyrene and radiation sterilization.
Description
The present invention relates to a kind of disposable hygienic food and drink tool and preparation method thereof.
At present, catering industry is extensive use of food containers such as a kind of disposable foamed plastics lunch box.The long-term use of this food and drink tool has certain toxic and side effect to human body, its machinery and physical property are also poor, and be not too convenient during use, with after not perishable and disappear and ruin, easily reclaimed to use and cause secondary pollution, if abandon then and can cause even more serious " white pollution " surrounding environment by the people.In the society also the someone produced disposable paper-made food and drink tool, but price is higher, raw material are in short supply, and intensity is also poor, therefore are difficult to promote.In addition, also the someone developed with the sclerotin powder of fibre of plant, animal etc. and was raw material making disposable food or beverage container, but in raw-material selection and preparation, also there is bigger problem, if any raw material sources more in short supply, the price that has is higher, especially therefore more complicated on manufacture craft yet there are no this product so far and comes out.
The objective of the invention is to overcome the deficiency of above-mentioned prior art, provide that a kind of raw material sources are wide, cost is low, mechanical strength is high, technology is simple, with the disposable hygienic food and drink tool of the easy molten water treatment in back and its preparation method.
The object of the present invention is achieved like this: this product includes a housing, and housing is mixed and made into by plant shell or cane or saw foam and starch based, calcium carbonate and water.The ectonexine of housing all scribbles polyvinyl alcohol and brightens coating.Internal layer brightens coating surface and outer field upper limb (the rim of a bowl) all scribbles water-soluble separating property polystyrene latex (waterproof action).
The optimum value of the raw material that above-mentioned said making housing is used is: plant shell or cane or saw foam are 47.5%.Starch based is 17.5%.Calcium carbonate is 2.5%.Water is 32.5%.
The preparation method of this product is:
(1) each raw material that will make housing mixing and stirring in proportion.
(2) raw material after will stirring adds housing and becomes in the base mold cavity, and the mould temperature control is at 200 ℃～220 ℃, die cavity is vibrated make raw material evenly be covered with die cavity.
(3) counterdie and patrix are exerted pressure to middle mould simultaneously, finish matched moulds, the demoulding and pressurize, the housing one-shot forming.
(4) the ectonexine spraying polyethylene alcohol to housing brightens coating.
(5) internal layer to housing brightens coating surface and water-soluble the separating property polystyrene latex of outer field upper limb spraying.
(6) carry out the width of cloth according to sterilization and packing.
The present invention compared with prior art has more advantage.Primary raw material is cane, shell or the saw foam etc. of plant, is again the hot press moulding moulding, has no side effect free from extraneous odour.Raw material sources are wide, product cost is low, technology is simple.Intensity is preferably arranged, and ectonexine all scribbles the material that brightens approximate imitative porcelain, and sense organ and result of use are all good.Not water-fast, not moisture resistance because of outer surface, can very fast corrosion scatter behind the chance water, it can not be reclaimed reuse, reach hygienic requirements.After this product corrosion is discarded is the good raw material of cultivated mushroom, also can make the animal foodstuff, and burying after rotting has been again fertilizer, can not bring " white pollution ".
Below in conjunction with embodiment the present invention is further described.
With disposable and convenient noodle bowl commonly used is example, and it is made main process and is:
(1) selects materials and be rice hulls, starch based (as rice, flour etc.), calcium carbonate and common water.The ratio of each raw material is selected for use by above-mentioned optimum value.Wherein, the effect of husk mainly is to form body frame.Starch based plays the adhesive effect.Calcium carbonate plays closely knit and adds the temperature resistance effect in man-hour.
(2) clean material is done a pond by the production scale size, fills with clear water, and husk is poured into, removes dust and sandstone, pulls out stand-by.
(3) stir, it is even to pour in the mixer each raw material into mix.
(4) charging, automatic control adds into the raw material that mixes in the bad mold cavity according to quantity.Becoming the mold tool is that upper, middle, and lower part is formed, and patrix leaves during charging, from top to bottom directly charging according to quantity.Mould temperature (adjustable) is controlled between 200 ℃～220 ℃.After raw material enters die cavity, vibrated simultaneously (electromagnetism, machinery and gas vibration all can), make raw material evenly be covered with die cavity.
(5) be hot pressed into base, power source is automatically controlled, hydraulic pressure.After raw material was covered with die cavity equably, counterdie and patrix were exerted pressure to middle mould simultaneously, can finish matched moulds, the demoulding, pressurize in 10～20 seconds.The one-shot forming of housing base substrate, base substrate wall thickness 1mm～1.5mm.And then hand spraying over to by manipulator.
(6) housing (base substrate) ectonexine sprays non-watertight coating, is buttressed by manipulator, respectively adorns a spray equipment up and down, simultaneously housing ectonexine spraying polyethylene alcohol is brightened coating, controllable thickness in 0.4mm, 2～4 seconds time.Through hot-forming housing, temperature is very high, and the coating top layer of being sprayed is very fast just can be dry.Spray back manipulator displacement, delivered the watertight composition spraying.
(7) spraying of housing internal layer and outer upper limb (the rim of a bowl) watertight composition is respectively adorned a spray equipment with the side below, specially is sprayed on inner surface and outer upper limb (this position palpus waterproof) with water-soluble separating property polystyrene latex.THICKNESS CONTROL is in 0.5mm, and the time is 2～4 seconds.
(8) baking typing after spraying finishes, was delivered on the baking line by manipulator again, carries out high temperature (about 150 ℃) baking, through baking typing in 4～5 minutes.
(9) bowl end lettering is realized by off-the-shelf equipment.Except that cup, dish, dish need the printing pattern pattern, an instant noodle bowl branding and label get final product.
(10) width of cloth is according to sterilization, and production line continues to transmit behind the lettering, the width of cloth photograph of sterilizing while sending, and direct sending is to the packing workbench.
(11) packing cartonning, strict with sterile working.
