Abstract
A disposable food container is made up of bean curd dregs, plant fibre and coagulant, which is prepared from carboxymethylcellulose, starch and water, through mixing, press shaping, drying and coating a layer of edible paraffine. Its advantages include easily available raw materials, low cost, and the possibility of being reclaimed, using as feed, or being biodegradated.
Description
The present invention relates to food container.
Supply is the food container (as snack box) of material with the Polymer in the market, has formed putative " white pollution ", in order to solve this serious pollution problem, therefore various reports about food containers such as improved snack boxs is arranged.For example Chinese patent (CN1137439A, 1996) report is a raw material with starch, adds xanthan gum, through mixing hot-forming making snack box.And for example Chinese patent (CN1107116A, 1994) report employing glutinous rice, rice, corn and vegetable fibre are snack box or the food container that raw material is processed into different shape.Though eliminated pollution, because of the cost high price also with regard to corresponding height, can't be accepted by market, and the country that China neither a grain affluence, therefore produce a kind of pollution-free and inexpensive food container, be that people expect the problem that solves for a long time.
China is bean curd big producing country, a large amount of soybean residues that in soybean curd production process, produce, and custom is used to feed pigs always, and is perishable when day heat has little time to handle, and becomes to draw rubbish to abandon and causes environmental pollution.It is that main material is made food containers such as snack box that the inventor considers to adopt with the wide inexpensive again soybean residue in this source, is a job highly significant.
The object of the invention provides a kind of with soybean residue, and vegetable fibre and coagulant are a kind of disposable food packing container that raw material is manufactured, and raw material sources are wide, and cost of price is cheap, and production technology is simple.
Disposable food packing container of the present invention is with soybean residue, vegetable fibre and be raw material as coagulant by the paste that carboxymethyl cellulose and starch are made, after fully mixed according to a certain ratio the stirring, compression moulding, drying, skim food grade paraffin forms on the inside and outside wall external coating again.
The proportioning of each constituent of raw material of disposable food packing container of the present invention is as follows:
Constituent weight %
Soybean residue 60-82
Vegetable fibre 12-30
Coagulant 6-11
Vegetable fibre can be waste paper, textile mills' lap waste, time loose thread, fiber crops, below grade, cotton bar skin, cornstalk skin, sugarcane skin etc.
Coagulant is to use carboxymethyl cellulose, and starch and water stir evenly the paste of making, and three's part by weight is followed successively by 1: 0.8-2: 2.5-4.Carboxymethyl cellulose is the commercial goods, and its performance is tasteless, odorless, harmless, soluble in water, and the aqueous system is transparent, is gluey, and starch can be wheat starch, and cornstarch etc., so the strong good penetrability of coagulant binding force are easy to preserve, and the surface can skinning.
Soybean residue is directly to ship from the bean curd originating firm, through the most moisture content of drop, proceeds processing.If soybean residue can not in time be processed, then can behind the most moisture content of drop, add propionic acid and evenly stir, carry out anti-corrosion treatment, in order to avoid soybean residue is rotten.The amount that adds propionic acid can require shelf-life length to change with aqueous ingredients in the soybean residue and soybean residue, for example the soybean residue aqueous ingredients is 18%, require 1 month shelf-life, then in 100 kilograms of soybean residues, add 350 gram propionic acid, as require 6 months shelf-lifves, then in 100 kilograms of soybean residues, add 450 gram propionic acid.
The production method of disposable food packing container of the present invention is as follows: after producing soybean residue that bean curd factory directly takes and using up moisture content through drop, again with hydroextractor dehydration (the soybean residue aqueous ingredients after general such dehydration is about 14%).After for example waste paper passes through step process such as pulverizing, immersion, rinsing, sterilization with vegetable fibre in addition, dewater with hydroextractor equally.Soybean residue after the dehydration is mixed the back with vegetable fibre by said ratio fully to be stirred, after fully stirring by proportioning adding coagulant again, compression moulding, drying, at inside and outside wall surface brushing skim food grade paraffin, promptly can be made into snack box or other food container of different shape again.
Advantage of the present invention: disposable food packing container of the present invention adopts soybean residue, and vegetable fibre and starch are that raw material is made, thus with after can recycle, also can sneak into hogwash as feed.If when losing in the open air, biodegradation is very fast, can not pollute.Raw material sources are wide, and cost of price is cheap, and production technology is simple, have the market competitiveness.
The present invention is further elaborated by following embodiment, but does not limit the scope of the invention.
Embodiment 1
From the most moisture content of soybean residue process drop that the bean curd originating firm directly comes, with common centrifugal dehydrator dehydration, aqueous ingredients is about 14% in the soybean residue of dehydration back again.With after the routine operation steps such as the pulverizing of waste paper process, immersion, rinsing, sterilization, dewater with hydroextractor too in addition.Soybean residue 75kg after the dehydration is mixed the back fully to be stirred with paper pulp 18kg, add the 7kg coagulant again (by carboxymethyl cellulose 1.6kg, wheat starch 1.6kg and water 3.8kg stir evenly the paste of making) fully stir after, being pressed into lid is the taper type snack box of divergence type with box, after drying, again at inside and outside wall surface brushing skim food grade paraffin.
Embodiment 2
From the most moisture content of soybean residue process drop that the bean curd originating firm directly comes, with common centrifugal dehydrator dehydration, aqueous ingredients is about 14% in the soybean residue of dehydration back again.With after the routine operation steps such as the pulverizing of cotton bar skin process, immersion, rinsing, sterilization, dewater with hydroextractor too in addition.Soybean residue 60kg after the dehydration is mixed the back fully to be stirred with cotton bar latex 30kg, add the 10kg coagulant again (by carboxymethyl cellulose 1.5kg, the paste that cornstarch 2.5kg and water 6kg stir and make) after abundant the stirring, being pressed into lid is the oblong packaging for foodstuff of connection type with box, after drying, again at inside and outside wall surface brushing skim food grade paraffin.
