Advantages of corn starch tableware production technology

In the traditional corn starch tableware making process, the starch gelatinization process needs to use a variety of chemical additives, which causes troublesome operation, inconvenient process control and cost reduction, and the rework rate is high, and some raw materials are not easy to purchase. A production method for degradable disposable starch tableware that is convenient for process control and operation. The method can produce products with higher qualification rate and lower cost, and the products are easier to degrade and recycle after use.
 

The process includes generalization of plant starch, uniform feeding, puffing molding and surface treatment processes. Among them, the gelatinization temperature in the vegetable starch gelatinization process is 60-80°C, the gelatinization time is 30-60 minutes, the weight percentage of each component of the materials used is vegetable starch 13-15, and additives 0,8- 12. Water balance, the auxiliary agent is an acrylic cationic substance.

 

Among them, the surface treatment is the dinner plate formed by shadow, and the products such as the dinner plate can directly sterilize the bacteria. Bowl and box products can be first sprayed with 1-6 UV gram light-curing resin on the surface, and then irradiated by an ultraviolet light generator for 1-3 seconds to become a finished product.

 

Compared with traditional technology, the new cornstarch tableware manufacturing process has the following advantages:

1. As the chemical process is improved, only one chemical additive is selected, and the powder mixing degree and time are reduced, so the process is easy to control and the operation is simple.

2. The auxiliaries 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%.

3. Due to the use of UV light curing resin for the surface treatment of the product, the resin has strong water resistance, oil resistance and antibacterial effects, so the qualified rate of the product is high, which can reach 90%.

4. Due to the improvement of water resistance and oil resistance, it is convenient to automate continuous production and shorten the processing time, so the comprehensive energy cost can be reduced by about 20%.

5. Degradation quality change rate> 90%, which is 6-10% higher than similar products.

 

In short, the new production method of corn starch tableware has the advantages of easy process control, simple operation, low cost, high qualification rate and easy degradation.
