The present invention relates to a rotating table dining table with low noise, and more specifically, it is rotatably installed on a dining table provided in a large restaurant or cafeteria so that a plurality of eaters rotate the rotating table on which a food container is placed at a position not on the dining table. It relates to a low-noise rotating table dining table that allows you to conveniently reduce and eat food suitable for taste as needed.

In general, a dining table is to provide a dining space where a large number of eaters can gather and eat in one place, and due to the advantage that the dining room can sit on a chair, it is widely installed in the canteens of homes, large restaurants, or large businesses. It has been used.

In particular, in the case of self-serving meals at a large buffet-style restaurant or a cafeteria of a large-scale business establishment, the eaters line up in turn and serve food placed on a fixed table, such as rice and side dishes, on a plate or plate. After that, I moved to the table and ate.

And those who lacked rice and side dishes moved to the fixed table again and took additional rice and side dishes to eat, and those who finished the meal threw the leftover food in the container and returned the plate or plate.

However, as described above, in the process of self-serving meals at large restaurants or canteens of large business sites, the meals were re-fixed to further reduce the inconvenience and lack of food in order to reduce the inconvenience of having to dispense food on a plate or plate by standing in line. Since the meal time is increased due to the hassle of moving to the table, the majority of eaters ate by dropping a large amount of food on a plate or plate at a time, and as a result, they could not consume all of the food, increasing the amount of food waste.

Unlike general garbage, such food waste contains a large amount of moisture, so it has a lot of difficulty in its disposal. In particular, if it is not treated quickly in summer, it acts as a factor that pollutes the surrounding environment along with the occurrence of odor due to decay.

Accordingly, various methods for reducing food waste are emerging due to the problem that an enormous national budget is required annually according to specialized treatment facilities and treatment costs in the treatment of such food waste.

In recent years, in order to compensate for this, a low-noise revolving table has been proposed, in which a diner can conveniently reduce an appropriate amount of food by rotating a revolving table on which a food container is placed at a seated position on the table.

This low-noise revolving table eliminates the inconvenience of moving meals in a line and dropping food on a plate or plate, and the hassle of moving to a fixed table when additional food needs to be removed. The amount of waste generated has been significantly reduced.
