1、 Material analysis:
The materials used in disposable tableware are not harmful to people, easy to degrade, and its production, use and destruction process will not be polluted, which ensures that it will not affect people's health. The overall quality of the product meets the requirements of food hygiene in China. After use, the tableware is easy to recycle, consume and handle. For example: mung bean starch has high viscosity, low water absorption, white and glossy color, but high cost; Potato starch has fine texture, white color and higher luster than mung bean starch. The smaller the water absorption and the lower the cost, the more suitable it is as an additive. The cellulose content of bamboo shoots and wheat bran is high, which is an excellent dietary fiber. However, the cost of using bamboo shoots is higher than that of wheat bran. The use of wheat bran is conducive to the overall utilization of agricultural and sideline products, and wheat bran and starch are easy to decompose.
2、 Material synthesis process flow:
At present, the production equipment of disposable tableware can adopt the existing set of fixed equipment, mainly including feeder, pulverizer, mixer, mixer, setting machine, drying device, ultraviolet disinfection equipment, conveying line and packaging production line
Plant starch, wheat bran and other main materials are crushed into powder, mixed with other additives according to a certain proportion, and mixed with water to make raw materials. Then some forming techniques are used to make chopsticks, spoons, plates and other tableware shapes, and special drying process is adopted to maintain their hardness and flexibility, And then after disinfection packaging can be put on the market.
Although the material cost of producing disposable tableware is slightly higher than that of ordinary disposable tableware, its social value is relatively higher, and its finished product is more beautiful than ordinary disposable tableware, which not only meets the demand of modern fashion consumption, but also makes better use of recyclable resources, low-carbon and environmental protection, and has low energy consumption and wide range of raw materials, In line with the requirements of sustainable development.
