Abstract

PURPOSE: To utilize a large amount of waste grain husks for producing various kinds of containers and to reduce the necessity of wood pulp by a method wherein the grain husks are powdered and mixed with edible glue, a paste material is formed therefrom after being exposed to vapor, a belt-like body is formed after being stretched by rollers, and the belt-like body is formed into a container with press applied by a molding die and drying applied afterward. CONSTITUTION: Grain husks are put into a crush mill 21 and crushed until they become powdery 22. Then, the powder 22 in 97% of volume is mixed with an edible powder such as carboxymethylcellulose in 3% of volume and exposed to vapor at 200 deg.C for 30 minutes and thereby a paste material 31 is formed. Then, the paste material 31 is made to pass through rollers 32 having a space in between, and the paste material is stretched by the rollers to become a belt-like body 220. The belt-like body 220 is thrust into a mold for concaved container by appropriate molding dies 41, 42, 43 with a pressing force approximately at 120 kg/cm<2> . A molded container 60 is guided onto a conveyer 52 and dried with a heater 51 at 60 deg.C-80 deg.C to become a finished product. Thereby, waste grain husks can be utilized effectively, and the amount of use can be reduced for wood pulp.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The invention of this application relates to a method of making a container from husks.

[0002]

2. Description of the Related Art Containers are widely used on a daily basis, and most of them are discarded after use. Most of these containers are made of paper or polypropylene (P.
P.), made from a chemical material such as polystyrene foam, and has the following inevitable drawbacks.

Paper containers cannot be heated and are made of wood pulp obtained by deforestation.

It has been proven that containers of chemical materials do not accept hot contents as toxic substances may be generated and these toxic substances cause cancer. In addition, the chemical materials do not biodegrade.

It is an object of the present invention to provide a method of manufacturing a container from husks in order to alleviate and / or prevent the above problems.

[0006]

In order to achieve the above object, a method for producing a container from the husks in the first invention is
(a) powdering the husks, (b) mixing the powder with an edible paste and exposing it to steam to form a paste material, (c) rolling the paste material into a strip, (d) the strip Is pressed by a mold for a container having a desired shape, and (e) a step of drying the molded container is performed.

In the method for producing a container from husks in the second invention, the mixing in the step (b) in the first invention is 97% powder.
It is characterized in that it is mixed at a ratio of 3% by volume and edible paste and exposed to steam at 200 ° C. for 30 minutes.

In the method for producing a container from husks in the third invention, the pressing force in the step (d) of the first invention is 120 kg.
It is characterized by being / cm ² .

In the method for producing a container from the husks in the fourth invention, the drying temperature in step (e) of the first invention is 60 ° C.
It is characterized in that it is -80 ° C.

The method for producing a container from husks according to the fifth aspect of the invention is characterized in that the edible paste according to the first aspect is carboxymethyl cellulose.

[0011]

According to the invention of this application, the husks are made into a powder, the powder is mixed with edible paste, and the paste is exposed to steam to form a paste material. It is possible to manufacture a container from the husks by pressing with a mold of a container having a desired shape, and drying the formed husks. Mix at a ratio of 3% by volume, expose to steam at 200 ° C for 30 minutes to form a paste material, and roll the paste material into a strip, which is placed in a mold of a container at a rate of about 120 kg / cm. ^A container can be manufactured from the husks by a 5-step manufacturing method in which it is pressed into a desired shape by being pressed with a pressing force of ² and then dried at 60 to 80 ° C.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The objects, advantages and novel features of the invention according to this application will be described below with reference to the drawings.

FIG. 1 is a block diagram showing a manufacturing process of a method for manufacturing a container from husks, and FIG. 2 is a side view showing a manufacturing process of the same manufacturing method.

As shown in the figure, the method for producing a container from a husk, such as rice husk, usually comprises five steps (a) to (e) shown in FIG. Then, the husks are poured into a crushing mill 21 and crushed to a powder form 22. In step (b), 97% by volume of powder 22 is mixed with 3% by volume of edible glue such as carboxymethyl cellulose. Then, the paste material 31 is formed by exposing it to steam at 200 ° C. for 30 minutes, and in the step (c), the paste material 31 is passed between the two rollers 32 forming a gap to form a belt 220, and the strip 220 is formed. ), The band 220 is placed in the mold of the concave container and the appropriate molds 41, 4 are used.
It is pushed with a pressing force of about 120 kg / cm ² by ² , 43, and in the step (e), the molded container 60 is guided onto the conveyor 52 and dried by the heater 51 at 60 ° C to 80 ° C.

The above-mentioned embodiments describe the preferred embodiments of the invention according to this application, and modifications and changes can be made without departing from the spirit and scope of the present invention.

[0016]

According to the invention of this application, a large amount of waste husks can be utilized for manufacturing various containers, which not only reduces the treatment of husks but also brings enormous benefits. .

The use of husks in the container also reduces the need for wood pulp and thereby reduces wood felling.
