In the traditional production of corn starch tableware, the starch gelatinization process needs to use many kinds of chemical additives, which makes the operation troublesome, inconvenient, process control and cost reduction. Moreover, the rework rate is high, and some raw materials are not easy to purchase, The method can produce products with high qualified rate and low cost, and the products are easier to degrade and recover after use.

該工藝包括植物淀粉概化、加料混勻、膨化成型和表面處理工藝。其中，植物淀粉糊化的工藝中糊化溫度是60-80℃、糊化時間是30-60分鐘，用料的各組分重量百分配比是植物淀粉13-15、助劑0，8-1.2、水余量、助劑是丙烯酸類陽離子的物質(zhì)。

The process includes plant starch generalization, blending, puffing and surface treatment. In the gelatinization process of plant starch, gelatinization temperature is 60-80 ℃, gelatinization time is 30-60 minutes, the weight percent ratio of each component is plant starch 13-15, auxiliary 0, 8-1.2, water surplus, auxiliary is acrylic cationic material.

其中，表面處理為:影化成型的盤、碟類等產(chǎn)品可直接消菌即為成品;碗、盒類等產(chǎn)品，可先在其表面噴涂1-6UV克光固化樹脂，再經(jīng)紫外光發(fā)生器照射1-3秒，即為成品。

Among them, the surface treatment is as follows: the finished products can be directly sterilized by the shadow shaped plates and dishes; Bowls, boxes and other products, can be sprayed on the surface of 1-6 UV curing resin, and then irradiated by UV generator for 1-3 seconds, that is the finished product.

與傳統(tǒng)技術(shù)相比，該新式玉米淀粉餐具制作工藝主要有如下優(yōu)點：

Compared with the traditional technology, the new technology has the following advantages
                       

一是由于改進(jìn)了化工藝，只是選用了一種化學(xué)助劑，并降低了粉化混度和時間，所以工藝易于控制操作也簡單。

First, because of the improvement of the pulverization process, only a kind of chemical additive is selected, and the pulverization mixing degree and time are reduced, so the process is easy to control and the operation is simple.

二是糊化工藝中所用助劑普通易得，較低，用量少，此一項能減少成本33%，并使總成本降低8-10%。

The other is that the additives used in gelatinization process are generally available, the price is low and the dosage is small. This can reduce the cost by 33% and the total cost by 8-10%.

三是由于采用了UV光固化樹脂對產(chǎn)品進(jìn)行表面處理，該樹脂具有較強(qiáng)抵水、抗油和消菌作用，所以產(chǎn)品合格率高，可達(dá)90%。

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

四是由于抵水、抗油性能提高，便于自動化連續(xù)生產(chǎn)和縮短了加工時間，所以綜合能源成本可降低20左右。

Fourth, due to the improvement of water resistance and oil resistance, it is convenient for automatic continuous production and shortens the processing time, so the comprehensive energy cost can be reduced by about 20%.

五是降解質(zhì)量變化率>90%，比同類產(chǎn)品提高6-10%

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

總之，該玉米淀粉餐具新式生產(chǎn)法具有工藝易于控制、操作簡單、成本低、合格率高和易降解等優(yōu)點。

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