Description

Manufacturing method of environment-friendly tableware

The invention relates to a method for manufacturing tableware, in particular to a method for manufacturing and molding environment-friendly tableware made from bean agricultural products.

Due to the shocking environmental hazards of styrofoam and plastic materials, governments of various countries have worked hard to develop relevant plastic restriction policies and encourage catering businesses to use non-plastic tableware; although most domestic catering companies no longer use styrofoam Foam tableware is replaced by paper tableware. However, paper tableware needs to cut down a lot of trees, which affects soil and water conservation, not to mention that in order to make paper tableware soften quickly without being affected by the moisture content of the food when it is filled with food, it usually must be in the tableware. The surface is coated with plastic film, which not only makes it easy for users to eat the plasticizer, but also makes the paper tableware itself not a very environmentally friendly material.

In order to solve the aforementioned problems of plastic tableware and paper tableware, Taiwan Patent Publication No. 500746 proposed the "Disposable Plant Fiber Environmentally Friendly Tableware Manufacturing Method and Additive Formula", which collects raw bran raw materials, washes, centrifuges, and grinds. The steps of mixing, molding, drying, ultraviolet sterilization, quality control, and packaging produce environmentally friendly tableware. The environmentally friendly tableware is made of plant waste and can be decomposed by the environment to achieve a more environmentally friendly effect. However, since the compression molding is performed immediately after mixing in the manufacturing step, and the high temperature is not limited for compression molding, the friction and heat generated by the raw materials after mixing make the raw materials have a higher temperature and cause agglomeration. The physical properties are unstable and cannot be directly processed. Perform compression molding.

The environmentally friendly tableware manufacturing method provided by Taiwan Patent No. I383765 is to wash, dry, filter, and classify the main raw materials with plant fibers, then crush the main raw materials and add auxiliary additives for mixing. Finally, the raw materials are mixed with Pour into the hot pressing equipment in a metering method, and use the hot pressing equipment to heat-press the raw materials into tableware rough embryos, and then trim the tableware rough embryos into finished tableware; it is an attempt to recycle agricultural waste into tableware that can be decomposed by organisms. , So as to replace products such as styrofoam, plastic or paper pulp, and become pollution-free and environmentally friendly tableware.

Although the tableware manufactured in the aforementioned I383765 patent case is more environmentally friendly than tableware made of plastic or pulp materials, the main raw materials must be washed, dried, filtered and sorted during the treatment process, which requires more equipment and processes.
