Abstract

A method for manufacturing a fruit tray by using the wastepaper is provided to reduce the cost and to save the energy by recycling the wastepaper through a simple manner, and to prevent the fruit from sliding by forming pores inside the tray. Impurities are removed after collecting the wastepaper at a wastepaper collection process. The wastepaper collected at the wastepaper collection process is inputted to a disintegrator, and is disintegrated at a disintegration process(10). The wastepaper disintegrated at the disintegration process is inputted into a mixer filled with the first mixture of water and desiccant, and is stirred to dissolve the disintegrated wastepaper well at a stirring process(20). The wastepaper disintegrated at the stirring process and the second mixture of water and desiccant are inputted into the forming device for forming a fruit tray shape at a forming process(30). The fruit tray is completed by drying for 30-40 minutes at 175-180 degree celsius at a drying process(40). Wax of 3 weight% and a catalyzer aluminum sulfate of 3 weight% are added to the first mixture of 100 weight%.

The present invention relates to a fruit tray using a waste paper and a manufacturing method thereof, and more particularly, to a fruit tray and a manufacturing method using a waste paper such as various boxes or newspapers.

Generally, the harvested fruit is transported to the consumer in a moving or packing box.

For example, apples harvested from a tree are placed in a moving box and transported to a packing place for packaging, and transferred apples are placed in a packing box and moved back to general demand.

Apples transported in this way had a disadvantage in that the commodity value was lowered due to wounds, scratches, bruises, etc. caused by collision with each other due to frequent raising and lowering or shaking during movement, and a fruit tray was used to prevent this.

However, the general fruit tray is easy to produce and low price, the fruit tray is made of a synthetic resin material with good use and aesthetics.

The fruit tray made of the synthetic resin material is not collected well, the collected synthetic resin fruit tray is not recycled well, causing a serious disadvantage of environmental pollution to mankind.

The conventional synthetic resin fruit trays are not recycled well after use, and when the synthetic resin fruit trays used for general farms are collected and disposed of, serious environmental pollution occurs during incineration and landfilling, and thus incineration and landfilling cannot be performed. There was a problem such as a secondary cost caused by disposal.

Accordingly, an object of the present invention is to provide a fruit tray and a method for manufacturing the same, which are produced by using waste paper so as to be easily incinerated and landfilled and recycled when devised to solve various problems as described above.

Method for producing a fruit tray using the waste paper of the present invention to achieve the above object,

In the manufacturing method of the fruit tray,

A waste paper collection process of collecting various waste papers and removing foreign matters; A pulverizing step of putting waste paper collected in the waste paper collecting process into a grinder and crushing the waste paper fed into the grinder; A stirring step of stirring the waste paper ground in the grinding step into a stirrer filled with a first mixture of water and a desiccant, so that the ground waste paper melts well; A molding step of molding the waste paper pulverized in the stirring step, and a second mixture of water and a desiccant, which are put into a molding machine in which a fruit tray-shaped mold is formed; The fruit tray formed in the molding step is characterized in that the drying step of drying for 30 to 40 minutes in a high temperature drying furnace of 175 ~ 180 ℃.

In the stirring step, it is also possible to further add 3% by weight of a degassing wax and 3% by weight of aluminum sulfate as a catalyst to 100% by weight of the first mixture of the source water and the desiccant to the stirrer.

Therefore, the fruit tray manufactured by this manufacturing process is simple in its manufacturing method, and is manufactured without using a compressor such as a press, so that sufficient pores are generated inside the fruit tray and protects the fruit encased in the tray during impact due to the pores. It is characterized by the fact that the surface of the tray is not smooth due to the non-compression, and the fruit does not slide well in the tray.

In addition, it is convenient to recycle after use, and when disposed, there is a feature that can be landfilled and incinerated.

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

1 is a process chart showing the manufacturing process of the fruit tray using the waste paper of the present invention.

In the method of manufacturing a container according to the present invention, as shown in FIG. 1, a predetermined amount of waste paper collected through various methods and paths is put into the grinder 10 and densely pulverized. At this time, in order to increase the efficiency of grinding, it is also possible to mix the appropriate amount of water.

The waste paper pulverized in the crusher 10 is introduced into a stirrer 20 filled with a first mixture in which water and a desiccant are mixed and stirred for a predetermined time.

As for the ratio of the said waste paper, water, and a desiccant, the ratio of 13-17 weight% of paper, 80-85 weight% of water, and 2-3 weight% of desiccant is preferable.

It is also possible to add 3% by weight of the degassing agent and 3% by weight of the catalyst to 100% by weight of the first mixture in which the water filled in the stirrer and the desiccant are mixed.

Usually, the desiccant uses epomin, the degassing agent uses wax, and aluminum sulfate is used as a catalyst.

When the waste paper is sufficiently melted by stirring in the stirrer 30 and melted in the first mixture sufficiently to form a second mixture, the second mixture is introduced into a molding machine 30 having a mold of a fruit tray to have a fruit tray shape. Molding is carried out so that.

As such, when molding without applying compression, sufficient pores are formed inside, so that the pores exhibit a buffering effect when an impact occurs.

When a certain type of fruit tray is molded, the dryer is moved and dried for 30-40 minutes in a high temperature drying furnace of 175 ~ 180 ℃.

The dried fruit tray is also packaged for each unit will be shipped.

As such, the fruit tray molded to a certain shape includes sufficient pores therein, so that when the impact occurs, the pores absorb the impact to protect the fruit.

In addition, the surface of the fruit tray is not smooth by molding without pressing the fruit tray. This prevents the fruit from slipping in the tray due to the uneven surface.

As described above, according to the fruit tray using the waste paper of the present invention and a method of manufacturing the same, it is possible to reduce the production equipment and production cost by preparing a simple method without applying pressure to the waste paper.

In addition, by using what has been used as a synthetic resin as a waste paper can be used to save environmental pollution and energy consumption, and can be collected and recycled again after use to prevent environmental pollution by disposal.

In addition, since the pores are formed in the fruit tray, the fruit is excellent in protecting against impact, and the surface is not smooth, thereby preventing the fruit from sliding in the tray.
