Abstract
The present invention relates to a pottery snack bowl and a processing process thereof. Pottery clay is used as raw materials and processed into powder; the powder and adhesive agents are uniformly mixed and molded into a bowl blank coated with films or soaked in water repellent agents to obtain products; and after discarded, the pottery bowls are still soil after weathering and decomposition. The present invention has the advantages that the process is simple, no waste is discharged in the machining process, the price of the products is low, and polystyrene snack boxes can be completely replaced with the pottery snack bowl.
Description
The present invention relates to the processing method of the tableware that a kind of fast food uses, exactly is a kind of processing method of ceramic bowl for snack.
Environmental protection has basic role in the strategy of sustainable development." white pollution " that the polystyrene mess-tin is caused arrived must improvement stage.Researching and developing degradable new material substituted polystyrene is one of effective way of administering " white pollution ".Now disclosed substitution material mainly contains cardboard, paper pulp, starch etc.For cardboard, paper pulp, its initiation material is timber and grass fiber, and the former need cut for forest will destroy the ecological balance, and the mess-tin that the latter processed still can not satisfy instructions for use, in addition, all environmental pollutions of various degrees in timber, its process of grass fiber.Starch cost height, the popularization and application difficulty.
Bowl for snack provided by the present invention is intended to the substituted polystyrene mess-tin, and its process and use all can not endanger environment later.
The present invention is raw material with potter's clay, is processed into a bowl base earlier, then cladding film or dipping water repellent agent and obtain bowl for snack on the bowl base.Concrete technology is as follows:
Select to make it loose behind the clean free of contamination potter's clay natural drying, sieve and roughly select to remove foreign material such as stone; Potter's clay after roughly selecting carries out high temperature and bakes, and one dehydrates, and two come sterilization; Pulverize after baking, sieving makes powder.Powder is made compound after the mixing and stirring according to a certain percentage with adhesive.With this compound moulding bowl base, typing after drying.The cladding thin film promptly is a bowl for snack on the bowl base after the typing, can use after sterilization.
Described potter's clay can be the earth that bare place is used, and perhaps other nonmetallic ore soil are as attapulgite etc.
Described adhesive can be inorganic, the organic bond of sticky rice juice or other frees from extraneous odour.From the angle of environmental protection, be good with sticky rice juice.
The film of cladding usefulness can be edible packing film or transparent food wrapping paper or oily wax wrapping paper etc.Above-mentioned these films all can be degraded, and can not endanger environment after discarding.
The bowl base also can not clad film outward, adopts the method for infusion of food level water repellent agent, also can use after drying, the sterilization.Water repellent agent solidifies the back and forms smooth, clean refreshing superficial layer, has the required anti-outlet capacity of disposable use.
Weathering under field conditions (factors) after this pottery bowl is discarded, to decompose be earth still finally, takes from soil, and also in soil, environmental sound.Certainly also recyclable, pulverize again and make powder production ceramic bowl for snack.
Raw material of the present invention is sufficient cheap, and technology is simple, does not also have any waste discharge in the production process, and product price has competitiveness, fully can the substituted polystyrene mess-tin.
Fig. 1 is the structural representation of ceramic bowl for snack, is made of bowl 1 and 2 on lid.
Fig. 2 is a process flow diagram of the present invention.
In conjunction with the accompanying drawings, embodiments of the invention are described below:
Natural drying after selecting clean free of contamination earth digging on the bare place, sending coarse classifier 3 to sieve in loose earth then roughly selects to remove foreign material such as stone and rubble, earth after roughly selecting send and carries out high temperature in the electricity oven dry road 4 and bake (300 ℃), after baking successively through pulverizer 5 and screening machine 6 pulverize, sieving makes powder.
With powder with sticky rice juice in accordance with regulations 2: 1 ratio (mass ratio) drop into fully to stir in the mixer 7 and make uniform compound.Compound is pressed into sheet material through moulding press 8.Sheet material is by rolling mould press 9 compression molding bowls 1 and lid 2 (bowl base).The bowl base send behind impregnation pond 10 dipping latexes or the varnish in drying shed 11 inner dryings, typing, after can pack warehouse-in behind ultraviolet sterilizing chamber 12 sterilizations.
Sticky rice juice adds water by per kilogram glutinous rice and boils the prescription processing that obtains 6-10 kilogram sticky rice juice.
Essential nontoxic, the safety of used latex or varnish, the temperature that ability is about 100 ℃ is as white glue with vinyl, acetic acid or cellulose butyrate varnish etc.
Bowl base after the moulding also can directly carry out finalizing the design behind the drying and dehydrating, then through mold pressing packaging machine cladding thin film, as edible packing film or transparent food wrapping paper or oily wax wrapping paper etc.
