Abstract

PURPOSE: A forming device and method for a disposable food container are provided to minimize environmental contamination through shaping the disposable food container by using grain hulls, water, and starch. CONSTITUTION: Hulls are collected to be inputted into a hopper(1). The hulls are transferred to a foreign material separator(2) by a conveyer(3). Then, the hulls are inputted to a hopper of an expander. The hulls are fed in one direction by the rotation of a feed screw to be crushed. Herein, water is discharged from a water tank through a pipe. The hulls are thermally expanded by the heat of a heater in the expander. The hulls are inputted to an agitator(7) while adding starch at a certain ratio. The mixture discharged from the agitator is transferred in one direction while being compressed. The mixture is shaped into a food container(9) by a press die of a former(10) at the end of a feed screw. The container is dried by the air supplied from an air compressor and coated by the coating liquid jetted from the upper and lower directions of the container.

Preferably, the aforementioned mixture of bran and starch maintains a 10: 1 ratio, and the moisture contained in the bran and starch maintains a water content of 20% to 30%.

The gel mixture discharged from the stirrer 7 described above is compressed while being transferred in one direction by the rotation of the transfer screw 12. A food container 9 of a predetermined shape (in the drawing, is an example) by using a mixture containing bran and water and starch by driving a press die (not shown) of the molding machine 10 formed at the end of the conveying screw 12. As shown in Fig. S50).

The food container 9 formed by the above-described molding machine 10 is dried by spraying air supplied from an air compressor or the like not shown when being transported through the conveyor 13 so as to maintain its shape. . Because of this, it is possible to specify the shape of the food container (9).

The food container 9 conveyed along the conveyor 13 described above may coat the inside and outside surfaces of the food container 9 by the coating liquid sprayed in the up and down direction of the food container 9 so as to maintain its durability. (See S60).

Therefore, as the food container 9 is coated on the inner and outer sides, the production of the food container 9 is completed.

As described above, according to a preferred embodiment, by injecting disposable food containers such as ramen containers, including the bran, water and starch discharged when the grains such as rice, barley, etc., are incinerated after use Or to minimize the environmental pollution of the air, soil and water quality when landfilling.

In addition, it is excellent in the heat retention of the food container by the characteristics of the bran itself, it is possible to significantly reduce the cost cost by forming the food container thermal expansion by molding.

In addition, by using an environmentally friendly material as a disposable food container material is to have a competitive advantage in the art by significantly increasing the preference of the product.

In addition, there is an advantage that can significantly reduce the cost required for post-management such as incinerators or landfills incinerated after using disposable food containers.
