In the traditional production of disposable corn starch tableware, many kinds of chemical additives are needed in the starch gelatinization process, which makes the operation troublesome, inconvenient for process control and cost reduction, and high rework rate, and some raw materials are not easy to purchase. Therefore, the manufacturer proposes a production method of degradable disposable starch tableware, which is convenient for process control and operation, and can produce high qualified rate and high cost Low cost products, and the products are more easily degraded and recycled after use.

该工艺包括植物淀粉概化、加料混匀、膨化成型和表面处理工艺。其中，植物淀粉糊化的工艺中糊化温度是60-80℃、糊化时间是30-60分钟，用料的各组分重量百分配比是植物淀粉13-15、助剂0，8-1.2、水余量、助剂是丙烯酸类阳离子的物质。

The process includes the generalization of plant starch, mixing, puffing and surface treatment. Among them, the gelatinization temperature of plant starch is 60-80 ℃, the gelatinization time is 30-60 minutes, the weight percentage ratio of each component is plant starch 13-15, adjuvant 0, 8-1.2, water surplus and auxiliary agent are acrylic cationic substances.

其中，表面处理为:影化成型的盘、碟类等产品可直接消菌即为成品;碗、盒类等产品，可先在其表面喷涂1-6UV克光固化树脂，再经紫外光发生器照射1-3秒，即为成品。

Among them, the surface treatment is as follows: the finished products can be directly sterilized by the shadow forming plate and dish; the products such as bowls and boxes can be sprayed with 1-6 UV gram UV curing resin on the surface, and then irradiated by the ultraviolet generator for 1-3 seconds.

与传统技术相比，该新式一次性玉米淀粉餐具制作工艺主要有如下优点：

Compared with the traditional technology, the new disposable corn starch tableware has the following advantages:

一是由于改进了化工艺，只是选用了一种化学助剂，并降低了粉化混度和时间，所以工艺易于控制操作也简单。

One is that the process is easy to control and the operation is simple because only a chemical additive is selected and the pulverizing mixing degree and time are reduced.

二是糊化工艺中所用助剂普通易得，较低，用量少，此一项能减少成本33%，并使总成本降低8-10%。

Second, the additives used in the gelatinization process are common and easy to obtain, the price is low, and the dosage is small. This can reduce the cost by 33% and reduce the total cost by 8-10%.

三是由于采用了UV光固化树脂对产品进行表面处理，该树脂具有较强抵水、抗油和消菌作用，所以产品合格率高，可达90%。

Third, due to the use of UV curable resin for surface treatment of the product, the resin has strong water resistance, oil resistance and sterilization, so the product qualification rate is high, up to 90%.

四是由于抵水、抗油性能提高，便于自动化连续生产和缩短了加工时间，所以综合能源成本可降低20左右。

Fourth, the comprehensive energy cost can be reduced by about 20 due to the improvement of water resistance and oil resistance, the convenience of automatic continuous production and the shortening of processing time.

五是降解质量变化率>90%，比同类产品提高6-10%

Fifth, the change rate of degradation quality is more than 90%, which is 6-10% higher than that of similar products

总之，该一次性玉米淀粉餐具新式生产法具有工艺易于控制、操作简单、成本低、合格率高和易降解等优点。

In a word, the new production method of disposable corn starch tableware has the advantages of easy control, simple operation, low cost, high qualified rate and easy degradation.
