1. Material analysis:
The materials used in the degradable disposable tableware are harmless to the human body and easily degradable. Its production, use, and destruction will not cause pollution and ensure that it will not affect human health. The overall quality of the product meets the requirements of food hygiene. The tableware is easy to recycle, consume and dispose of after use. For example, mung bean starch has a high viscosity, low water absorption rate, white color, but high cost; potato starch has fine texture, whiter color, higher gloss than mung bean starch, low water absorption rate, lower cost, and is more suitable as an additive. Bamboo shoots and wheat bran have high cellulose content, which is an excellent dietary fiber, but the cost of using bamboo shoots is higher than that of wheat bran. The use of wheat bran is conducive to the comprehensive utilization of agricultural and sideline products, and wheat bran and starch are easy to decompose.
2. Processing flow of synthetic materials:
At present, the production equipment of degradable disposable tableware can adopt the existing complete sets of equipment, which mainly include feeders, pulverizers, mixers, mixers, setting machines, drying devices, ultraviolet disinfection equipment, conveyor lines, and packaging lines. The production process is as follows:
The main ingredients such as vegetable starch and wheat bran are crushed into powder, mixed with other applicable additives in a certain proportion, mixed with water to make raw materials, and then made into the shape of chopsticks, spoons, plates, and other tableware. It maintains its hardness and flexibility through a specific drying process, and can be put on the market after sterilization and packaging.
The material cost of the production of biodegradable disposable tableware is slightly higher than that of ordinary disposable tableware, and its social value is relatively high, which meets the needs of modern people's fashion consumption. It is low-carbon and environmentally friendly, has low production energy consumption, a wide range of raw materials, and is in line with sustainable development. Requirements.
