Speed, more environmentally friendly recycling benefits, to achieve the reuse of agricultural waste.

According to the press, plastic products have the advantages of light weight, no water penetration, and high plasticity. Therefore, plastic products have been widely used so far, such as common plastic bowls, cups, spoons, knives, forks, straws, etc.; Products are not easy to be decomposed and will release environmental hormones (such as bisphenol A, plasticizers, etc.), but it will cause damage to the environment. In addition, in recent years, with the gradual rise of environmental awareness, plastic products have gradually been popularized by the public. Disabled and eliminated.

In order to avoid the continued use of plastic products to pollute the environment, some manufacturers have developed environmentally friendly tableware made from plant fibers. The conventional manufacturing process of plant fiber environmentally friendly tableware (as shown in the first picture), the main process steps are as follows, Step 1: The raw material mixed with plant fiber is made into an environmentally friendly tableware semi-finished product by an article forming machine; Step 2: The environmentally friendly tableware semi-finished product is directly dried to fix the shape; Step 3: The environmentally friendly tableware semi-finished product is completed, That is to say, finished environmental protection tableware. In this way, the natural vegetable fibers that can be decomposed are added by using tableware ingredients, and the source of natural plant fibers can be the residues of food recycling (such as coffee grounds or bagasse, etc.), so that the environmentally friendly tableware produced is environmentally friendly effect.

However, in order to make the vegetable fiber environmental protection tableware still have the same hardness and heat resistance as the plastic tableware, the conventional plant fiber environmental protection tableware must be increased in the thickness setting of the product forming machine during manufacturing, so that the product The relative increase in the thickness of the semi-finished environmentally-friendly tableware results in a relatively heavy product of the final environmentally-friendly tableware, which not only consumes more environmentally friendly raw materials and costs, but also results in a thicker environmentally friendly tableware that is less likely to be decomposed. The time required for decomposition increases, resulting in lower environmental protection benefits.

According to the plant fiber environmentally friendly tableware process disclosed by the present invention, the process method includes: firstly putting raw materials with plant fibers into an article forming machine, and the article forming machine forms the raw materials into a preset tableware semi-finished product; and the tableware semi-finished product It is fed into a boiling device, which has a liquid with a preset temperature (for example: a liquid between 20°C and 150°C), soaks the semi-finished tableware in the liquid of the boiling device to perform the cooked operation, and completes the cooked tableware The semi-finished products become finished tableware; send the finished tableware to a dehydration device, and the dehydration device performs dehydration and other dehydration operations on the finished tableware; send the finished tableware products that have completed the dehydration operation to an oven device, and the oven device processes the tableware The finished product is sterilized, that is, the environmentally friendly tableware made of plant fiber is completed.

The technical feature of the present invention is that the semi-finished tableware made by the article forming machine is immersed in the liquid of the boiling equipment to perform the cooked operation, and the shape of the semi-finished tableware can be fixed (shaped) and the structure is strengthened through the cooked operation, so that Finally, the thickness of the finished tableware can be reduced without affecting its hardness and heat resistance. In addition to reducing the amount of raw materials used, reducing the thickness of the tableware can increase the speed of decomposition and have more environmental benefits.
