Description

Plant fiber environmental protection tableware process

The invention relates to a vegetable fiber environmentally-friendly tableware process, in particular to a tableware semi-finished product made by an article forming machine, which is immersed in a boiling temperature device with a preset temperature for the ripening operation, thereby fixing the shape of the tableware semi-finished product. (Fixing) and structural reinforcement, so that the finished finished tableware can be reduced in thickness without affecting its hardness (strength), and the amount of raw materials can be reduced, thereby reducing the thickness of the tableware and increasing the decomposition. Speed, more environmentally friendly recycling benefits, to achieve agricultural waste recycling.

According to the plastic products, they have the advantages of light weight, no water penetration and high plasticity. Therefore, plastic products have been widely used, such as common plastic bowls, cups, spoons, cutlery, straws, etc.; however, due to plastics The product is not easily decomposed and will release environmental hormones (such as bisphenol A, plasticizer, etc.), which will cause environmental pollution damage. In addition, with the gradual rise of environmental awareness in recent years, plastic products have gradually been popular. Disabled and eliminated.

In order to avoid the pollution of the environment caused by the continued use of plastic products, some manufacturers have developed environmentally-friendly tableware made of plant fibers, and the manufacturing method of the vegetable fiber-friendly tableware (as shown in the first figure), 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 for fixed forming; Step 3: Finishing the environmentally-friendly tableware semi-finished product for drying operation, That is, the formation of environmentally friendly tableware. Thereby, the natural plant fiber which can be decomposed is added by using the tableware component, and the source of the natural plant fiber can be the residue of food recovery (such as coffee grounds or bagasse), so that the environmentally-friendly tableware produced is environmentally friendly. efficacy.

However, in order to make the vegetable fiber eco-friendly tableware still have the same hardness and heat resistance as the plastic tableware, the conventional plant fiber environmental protection tableware must be manufactured to increase the thickness setting of the product forming machine, so that it can be made through the article forming machine. The relative thickness of the semi-finished products of the environmentally-friendly tableware has increased, resulting in the final product of the environmentally-friendly tableware. The product is quite heavy, which not only requires more environmentally-friendly raw materials and costs, but also forms a thick environmentally-friendly tableware that is less likely to be decomposed. The time required to decompose is increased, resulting in lower environmental benefits.

According to the invention, the method for manufacturing the vegetable fiber environmental protection table comprises the steps of: firstly placing the raw material of the plant fiber into an article forming machine, and forming the raw material into a predetermined tableware semi-finished product by the article forming machine; Feeding into a boiling device, the boiling device has a liquid with a preset temperature (for example, a liquid between 20 ° C and 150 ° C), and the semi-finished products of the tableware are immersed in the liquid of the boiling device to perform the ripening operation, and the tableware for the ripening operation is completed. The semi-finished product becomes the finished product of the tableware; the finished product of the tableware is sent to a dewatering device, and the dewatering operation is performed by draining, drying and the like of the finished tableware by the dewatering device; the finished tableware for the dewatering operation is sent into an oven device, and the tableware is placed by the oven device The finished product is sterilized, that is, the environmentally-friendly tableware made of plant fibers 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 device to perform the aging operation, and the shape of the semi-finished tableware can be fixed (formed) and structurally enhanced by the aging operation. Finally, the thickness of the finished tableware can be reduced without affecting the hardness and heat resistance. In addition to reducing the amount of raw materials, reducing the thickness of the tableware can increase the speed of decomposition and provide more environmental benefits.

The features and advantages of the present invention will be described in detail in conjunction with the accompanying drawings. The present invention is described in detail, but does not limit the scope of the invention in any way.

Referring to the second figure, the present invention discloses a vegetable fiber environmental protection tableware process, and the manufacturing method thereof comprises:

Step 100: The raw material of the plant fiber is placed in an article forming machine, and the raw material of the plant fiber is used to form a semi-finished product of the preset shape. The plant fiber may be a mixture of one or more of corn flour, sweet potato, coffee grounds (shell), bagasse, bamboo powder, rice husk, wood flour or agricultural waste. The article forming machine may be an injection molding machine, a blow molding machine, an extrusion molding machine or a polymerizable molding apparatus. The shape of the cutlery semi-finished product may be a straw, a dish, a spoon, a chopstick, a cup, a knife and a fork, and the like.

Step 110: feeding the cutlery semi-finished product of the previous step into a boiling device, the boiling device having a liquid of a preset temperature (for example, a liquid between 20 ° C and 150 ° C), soaking the semi-finished product of the cutlery in boiling The liquid of the equipment is used for the ripening operation, and the finished semi-finished product of the ripening operation can be a finished tableware.

Step 120: feeding the finished tableware of the ripening operation in the previous step into a dewatering device, and performing dewatering operation on the finished tableware by the dewatering device; for example, the dewatering device may drain and dry the finished tableware. operation.

Step 130: Feeding the finished tableware that has been dehydrated in the previous step into an oven device, and performing high-temperature sterilization operation on the finished tableware by the oven device, that is, completing the environmentally-friendly tableware made of plant fibers.

After the step 130 is completed, the finished tableware that has completed the high temperature sterilization operation can be sent to a packaging device, and the finished tableware that has completed the high temperature sterilization operation is packaged by the packaging device.

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 device to perform the aging operation, and the shape of the semi-finished tableware can be fixed (formed) and structurally enhanced by the aging operation. Finally, the thickness of the finished tableware can be reduced without affecting the hardness and heat resistance. In addition to reducing the amount of raw materials, reducing the thickness of the tableware can increase the speed of decomposition, and more environmentally friendly recycling benefits. Reuse of agricultural waste.
