Abstract

PURPOSE: A manufacturing method of a biodegradable disposable bowl is provided to minimize air pollution by not exhausting toxic substances in a process of incinerating food waste and to recycle the food waste for fertilizers or feed stuff by mixing the food waste with agricultural products having high bonding property such as sweet potatoes, potatoes, rice hulls and rice bran. CONSTITUTION: Raw material of a bowl including sweet potatoes, potatoes, rice hulls and rice bran are crushed and fermented in water. Herein, fermenting the raw material is for swelling a bowl well. The fermented material is picked up from the water and dried. After that, the dried material is mixed each other regularly and mixed with edible oil. The dried material contains about 10-19% of moisture content. The raw material is manufactured into a bowl in a specific die(A). The bowl die completes the bowl by raising the temperature up to 140-250deg.C. The bowl is pressed between the die frame and a press(B) and completed in a desired shape by the rising temperature. The completed bowl(C) is heated at a high temperature of 220-300deg.C and coated by vegetable property of oil. Finally, the bowl is pressed again. The bowl is made by cheap raw material and rotten out without causing any environmental pollution. In addition, the bowl has a high intensity for the bowl is coated by oil.

Description

Pollution-free disposable container and manufacturing method {A Depollute Courage and Manufacturing Method}

The present invention relates to a pollution-free disposable container and a manufacturing method.

Conventionally, in manufacturing disposable machines, since synthetic resins, silver foil, paper, etc. are used as raw materials, they remain as pollutants after use to discharge enormous wastes. It is pointed out as a problem of the world environment as a semi-natural protection product polluting water quality and air, and in particular, the replacement products are urgently needed due to the problem of environmental hormone extracted from disposable containers.

The present invention is to solve the above problems,

To provide goods that are beneficial to human life, livestock, and the natural environment (such as soil, water quality, and air pollution) using sticky sweet potatoes, potatoes, rice hulls, and rice bran,

When burning food wastes, it aims to minimize air pollution by releasing no toxic substances and to be beneficial when recycling food and fertilizers even if they are included in food wastes.

In order to achieve the above object,

The present invention comprises the steps of crushing sweet potatoes, potatoes, rice husk, bran and soaked in water and fermented;

After fermentation, dried in water, dried and mixed with food oil;

A drying step of drying the mixed raw materials such that moisture is about 10-19%;

Inserting the raw material into the container production frame and raising the temperature of the production frame to 140 degrees-250 degrees to complete the container;

After completing the container of the desired shape, it is characterized by consisting of a step of coating the vegetable oil at a high temperature of about 220 degrees-300 degrees and then pressing it again.

1 is an explanatory view of a container production of the present invention.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

The present invention first pulverized sweet potato, potato, rice husk, rice bran, etc., which is a raw material of the container, soaked in water and fermented.

The reason for fermenting the container raw material in the above process is to make it swell well when forming the container.

After fermentation, dry and dry in water, and when the drying is completed to some extent, mix the ingredients evenly, and then mix the edibles.

At this time, the content of water after drying is preferably about 10%-19%.

When the raw material mixing process is completed as described above, the raw material is put into a predetermined mold to produce a container. The raw material is put into a container forming mold as shown in A of FIG. Will be.

In this case, the container mold is raised to a temperature between 140 degrees and 250 degrees, and the container is completed. The principle of completion of the container is that the volume is increased when the temperature is increased while being pressed between the container mold and the press. Is completed.

Then, after the desired shape of the container is completed, after raising the temperature of the container to a high temperature of 220 to 300 degrees, sprinkled with vegetable oil and then press again to coat the container is finished.

That is, the present invention comprises a fermentation step of crushing sweet potatoes, potatoes, rice husk, bran and soak in water;

Drying, drying and mixing in water after fermentation, and mixing the food oil mixed with food oil;

A drying step of drying the mixed raw materials such that moisture is about 10-19%;

A container manufacturing step of completing the container by inserting the raw material into the container production frame and raising the temperature of the production frame to 140 degrees-250 degrees;

After completing the container of the desired shape, it is sprinkled with vegetable oil at a high temperature of about 220-300 degrees, and then pressed again to form a coating step.

As described above, since the present invention is made of a cheap material as a raw material, it is relatively inexpensive and rots after being discarded, and thus does not adversely affect the environment.
