Description

Rice Refrigeration Unit {RICE REFRIGERATION DEVICE}

The present invention relates to a rice refrigeration apparatus, and more particularly, by using a thermoelectric element to cool the air and discharge the cooled air to the upper portion of the storage tank in which the rice is stored, the energy efficiency is good and noise is not generated, as well as storage A rice refrigeration apparatus which prevents condensation of moisture and freezing of rice inside a tank.

Generally, when the humidity and temperature of the space where the rice is stored are high, rice worms are generated and the quality of the rice is reduced. Therefore, the rice is preferably less moisture and stored at a low temperature (temperature around 14 ℃).

Accordingly, in recent years, a rice refrigeration apparatus has been developed that can store rice at a low temperature by cooling the space in which the rice is stored to a constant temperature to maintain the temperature.

Republic of Korea Utility Model Publication No. 20-0331817, Republic of Korea Registered Utility Model Registration No. 20-0313073 and Republic of Korea Patent Publication No. 10-2004-0052279 are storage tanks in which rice is stored as a refrigerant pipe passing through the refrigerant A rice refrigeration apparatus is disclosed that directly cools a storage tank by encapsulating the refrigerant and compressed by a compressor and cooled by a cooler in a refrigerant pipe surrounding the storage tank.

However, since the conventional rice refrigerating device compresses, cools, and evaporates the refrigerant, energy consumption is not only required for the compression and cooling of the refrigerant, but also a lot of noise is generated from the compressor compressing the refrigerant, and a refrigerant that is an environmental pollutant is used. Has the disadvantage.

In addition, since the conventional rice refrigeration system is a structure in which the storage tank is directly cooled, water condensation is generated on the inner wall surface of the storage tank, and rice is in contact with the condensation to reduce the quality of the rice as well as near the inner wall surface of the storage tank. It takes a long time for cold air to penetrate into the inside of the rice, so the distribution of cold air is uneven. Even near the inner wall of the storage tank has a problem that the rice is frozen while the water is frozen due to condensation and excessive cooling.

The present invention is to solve the above problems, the object of the present invention is to use a thermoelectric element as a cooling means for cooling the inside of the storage tank in which rice is stored, as well as low energy consumption, low noise generation and environmental pollutants It is to provide an unused rice refrigeration unit.

In addition, another object of the present invention is to cool the air by the thermoelectric element and discharge the cooled air to the upper portion inside the storage tank in which the rice is stored indirectly cooling the rice to generate moisture condensation inside the storage tank in which the rice is stored. As the cold air is discharged to the upper portion and lowered, it penetrates evenly inside the rice to provide an even distribution of cold air and at the same time provide a rice refrigeration apparatus in which the rice does not freeze.
