Food manufacturing techniques that are used as raw materials to achieve environmental protection goals have long been well known, for example, No. 710438026" Jianwei (hereinafter referred to as the case No. 826) has been disclosed in patent applications such as "Method for Making Environmentally Friendly Dinner Plates" (hereinafter referred to as "Method for making trays" in US Patent No. 550000). The technology disclosed in the case No. 826 'is based on the original grains of grains and plant matter (or powder of tree shrews), blended with water, steamed for a period of time, and #cooled to a certain temperature. , Then High pressure is applied into the mold and then formed into tableware; although the raw materials used for this tableware are mainly natural, they must be formed through high temperature and high pressure processes (such as Luo place) in the process of making utensils. The required processing conditions are relatively strict, and the contained plant matter or cassava (starch) ingredients will make the cutlery made apparently poor in the humidity and humidity resistance, especially the starch is easily susceptible to moisture. Mold and deterioration, and these phenomena are no different for eating utensils with high safety standards

Invention Description (2) is a fatal flaw. The technology disclosed in the 〇-9 case and the US Patent No. 5 0 0 889, the material used in the organic respect is a natural plant with a clear stripe beam. Vitamin 蛊 脔 忒 short fiber male .1 怍 is beaten, and then mixed with starch as an adhesive, then fully stirred and gelatinized into a gelatinous mixture, which is compressed and dried using a fine mesh breathable mold. After that, it is processed into a tableware and other utensils through a mold-setting process of heating and pressurizing molds, and finally can be completed after drying and solidification. Therefore, its process is obviously far more complicated than the aforementioned case No. 826. 'Because starch is used as an adhesive, there are still many problems such as resistance to water and moisture', and even mildew. As for the use of natural short fibers as the substrate, not only the steps for obtaining materials are complicated, but the structure formed by short fibers Moreover, the texture of the product will be porous and loose, and its ability to prevent leakage and water will be tested. As for the traditional technique of making paper cups or paper plates and tableware from paper, raw materials for papermaking must be obtained from wood, and the acquisition of wood will also have an impact on the ecology ’and consume precious natural resources. On the other hand, 'the above two known technologies must use a large amount of water in the production process'. Relatively, a lot of wastewater will be a threat to T-guarantee, and the treatment of wastewater will cause production costs. [Summary and Purpose of the Invention] The main purpose of the present invention is to provide an environmentally friendly disposable container for food that can be naturally decomposed and can even be used as fertilizer or feed. Thanks to this

Description of the invention (3) The disposable disclosed in the Ming Dynasty is made of organic raw materials made of natural coriander skin, combined with non-toxic and naturally decomposable adhesives and fillers, so it can be used in a natural environment. Medium decomposition 'can even be used as fertilizer or feed, and 容 再 33 之 玟 3' can be divided or re-used in the loss of 柰; for fertilizer, or feed, it is a kind of environmental protection and has a very high Disposable containers for disposable foods of great value. A secondary object of the present invention is to provide a manufacturing technology of a disposable container for food, which is easy to manufacture, has low raw material price, easy to obtain raw materials, and meets environmental protection requirements. According to the disclosure, the “process for making a disposable container for food that can be naturally decomposed” is mainly a powdery substrate made of cereal rind, a filler (calcium carbonate; Ca 1 ci um Carbonate), and an adhesive. Agent (polyvinyl alcohol; PVA 'Polyvinyl Alcohol), and the release agent are mixed uniformly in the proper proportion' and then mixed with water as the medium, so that the powdery substrate and the filler are bonded into a kind by the bonding effect of the adhesive. A plastic mixture, which is then formed into a food-free disposable container by pressure molding (such as hydraulic molding), and then subjected to a simple drying and waterproof treatment, which can be made into a fine-grained and environmentally-friendly Food-free disposable containers. ^ Fa, the main raw material used is cereal rind. Because the output of cereals is extremely high, the relative value of cereal rind after taking out grains is also relatively great = quantity. Generally speaking, it is treated as waste, even if it is used for other purposes. , Its pot grid is also very cheap, and the acquisition of raw materials is not difficult; on the other hand, most of the so-called environmentally friendly tableware are mostly made of wood or paper.

Description of the invention (4) Because it is not easy to obtain wood, it is also necessary to cut down forest trees to obtain 'so its cost is relatively high', which is inferior to the economics of the present invention. For the purpose of obtaining material tree stumps, it is a natural source of data. Increasingly precious and dwindling environmental words today are more difficult to use. This is in addition to indirectly affecting the ecological development and even causing major problems of soil and water conservation. It is another object of the present invention to provide a fine-texture leave-on content for food. 'As the present invention uses a powdery cereal rind, and then uses CAC03' Calcium Carbonate 'as a filler' for filling food The gap in the weaving group of the disposable container makes it possible to obtain a disposable disposable container for high-quality food, which is not as loose as a fibrous texture. ^ The disposable container disclosed in the invention only uses a small amount of water during the production process, and all of this water is used to prepare a slightly viscous composite material. Therefore, during the production process, There will not be a large amount of waste water, which is of great help to% guarantee and cost reduction.

Description of the invention (6) In addition to the above three constituent substances, 'depending on the actual production process, an appropriate amount of release agent (such as boric acid core 03) is added to become a component of the composite material layer 10. First, and in principle, it is better to add eight in the form of liquid butterfly water; otherwise, it can also be applied directly on the surface of the cavity of the molded disposable container 10 Food-grade release agents such as grease and water to help release molds from disposable containers. The powdery substrate is obtained from the outer skin of cereals (such as rice and wheat), and the outer skin is ground into a very fine powder by a grinding device. In principle, this powdery substrate is It is better to pass more than 80 mesh. Filler is CaCo3; Calcium Carbonate is used to fill the gaps of the composite material to increase the compactness of the composite material. Polyvinyl Alcohol (PVA) can pass water as a lubricant, so that a mixture of these three basic constituents can form a slightly viscous composite material by bonding to facilitate the process.

Description of the invention (ΙΟ) ~ ^ — The general characteristics of a CCP PVA ---_ ^ 目 3__ΙΓ ^ ^ __ White to pale yellow particles or powder f is really better than Emperor UDM 31. υ. Τ ~ 〇 The cooked text is qualitatively heated for a long time to more than 160 ° C and gradually turns yellow. Above 200 ° C, it quickly discolors and starts to decompose at about 220 ° C, and completely decomposes above 300 ° C. It is called high quality, solvent-resistant, hygroscopic, weak-acid and weak-salt. It is highly stable to animals, vegetable oils, petroleum-based hydrocarbons, esters, ketones, and higher alcohols. It is the best solvent-resistant material. One. It has lower hygroscopicity than other water-soluble polymers and is less affected by humidity. Damin PVA film except H20 is barrier to H2, N2, C02 and other gases. Light resistance: 4ι 04 * ~ '~~~-Quality is not affected by light. Film-forming properties PVA has excellent film-forming properties. Its physical properties such as tensile strength, tear strength, and abrasion resistance are better than other water-soluble resins. Non-toxic Pure PVA is not harmful to the human body; for example, stick drugs are used as adhesives. Now 7 knife β ,. ------- (Table 1) linsn C: \ Program Files \ Patent \ p-〇157tw.ptd page 13
