Abstract
The utility model relates to a method for making food or beverage utensils with potatoes. Potatoes are used as a raw material; starch and potato residue of the potato are separated, and the potato residue is processed and manufactured into additives; an auxiliary agent is added into a heatable container with a stirring blade; reaction products are quantitatively distributed in a mould for heat forming after sufficient reaction; then, a formed product is treated by demoulding, edge shaping, coating and pressure heat setting; finally, the product is checked and packed. The product manufactured by the utility model has the advantages of white and smooth surface without adding any pigment, light weight and low product cost. Besides, the color of the product can be arbitrarily selected according to different purposes. The product can be discarded after being used, and the product can completely biodegraded after being discarded.
Description
Technical field
The present invention relates to a kind of dining utensil, specifically is a kind of biodegradable dining utensil of manufacturing with potato.
Background technology
Along with the variation that people's food habits takes place, urgent pursue material benefit, quick, health, efficiently, food and drink easily, obtained developing rapidly as the fast food catering industry of the symbol of modernization civilization, and be subjected to people's favor day by day.But present employed fast food ware majority is made by the EPS expanded plastic.After going out of use, this kind plastics dining utensil can not rot, utmost point difficult for biological degradation, reclaim difficulty, burn and to produce toxic gas, thereby, become " white pollution " that make us startling along with the increase of using discarded amount, seriously pollute physical environment, the broken eubiosis of having encircled, danger utmost point human existence.
Summary of the invention
The object of the present invention is to provide a kind of biodegradable dining utensil of manufacturing with potato, its abundant raw material, technology are simple, with low cost, three-waste free discharge, can all biological degraded after discarded, eliminated white pollution, protected ecotope.
The object of the present invention is achieved like this: a kind of biodegradable dining utensil, the component of its this dining utensil and weight percent are: potato 75-90%, vegetable fibre 8-23% and auxiliary agent 0.01-0.05%, its above-mentioned each component content sum equals 100%.
Wherein, described potato can substitute with Ipomoea batatas, sweet potato, pachyrhizus, sweet potato, cassava, yam bean, taro or konjaku; Described vegetable fibre is crop stalk, weeds, grass roots or velveteen; Described auxiliary agent is ammonla alum NH
4Al (SO

2.12HO or potassium alum KAl (SO
4)
2.12H
2O.
The procedure of processing of this dining utensil: 1) at first the raw material potato is carried out selected, cleaning, pulverizing, screening, potato slag and separate with starch; 2) starch is stand-by after washing, dewater through albumen sepn, eddy flow stream; 3) the potato slag is made additive after washing, bleaching, drying; 4) then stand-by yam starch and potato slag additive and auxiliary agent can be heated and be had in the container of stirring by weight dropping into, be warming up to 70 ℃-85 ℃ and ceaselessly stir and react; 5) after question response is finished, add vegetable fibre by weight, it is mixed, quantitatively inject in the mould through helical stir; 6) pressure expanded molding in 200 ℃ ± 10 ℃ temperature environments; 7) work in-process after the moulding enter the coating apparatus coating after the demoulding, deburring; 8) after pressure heat setting type get product.
Advantage of the present invention is that abundant raw material, technology are simple, with low cost, three-waste free discharge, and is harmless to HUMAN HEALTH in the use, can degrade by all biological after discarding, and eliminated white pollution, protected ecotope.
Description of drawings
Table 1 is a procedure of processing schema of the present invention.
Embodiment
The present invention is described in detail in detail below.
As shown in table 1, at first the raw material potato being carried out selected, cleaning, pulverizing, screening, potato slag separates with starch, starch is stand-by after washing, dewater through albumen sepn, eddy flow stream, the potato slag is made additive after washing, bleaching, drying stand-by, then with yam starch and potato slag additive and auxiliary agent ammonla alum NH
4Al (SO
4)
2.12HO dropping into together by weight percentage to heat and to have in the container of stirring, be warming up to 70 ℃-85 ℃, and ceaselessly stir and react, after question response is finished, add the vegetable fibre crop stalk by weight, it is mixed through helical stir, quantitatively inject in the mould, pressure expanded molding in 200 ℃ ± 10 ℃ temperature environments, the work in-process after the moulding enter the coating apparatus coating after the demoulding, deburring, and final pressure heat setting type gets product.
In the above-mentioned procedure of processing, its potato slag bleaching can not be adopted fluorescent bleaches, with the weave construction of tamper-proof original fiber.
Product by the present invention makes can be used in the microwave oven and heat, and brews through 100 boiling water and still not influence use.
