Description

Rice dispenser {RICE DISPENSER}

The present invention relates to a rice dispenser, and to a rice dispenser that is not limited to the type of container and the quantitative measurement of the rice is made accurately.

The rice dispenser can be defined as a device that automatically supplies the rice contained in the hopper to a specific container by weighing an appropriate amount.

Such a rice dispenser has an advantage in solving hygienic problems by excluding the use of a spatula in large-scale self-serving such as schools and companies, and the frequency of use is increasing recently.

In this regard, Patent Document 1 (Japanese Laid-Open Patent Publication No. 2019-37163) discloses a food material supply device that improves the feed rate and weight accuracy of rice to a food material container.

However, in Patent Document 1, since the weight of the rice is weighed after the rice is put into the container, there is a disadvantage in that there are many errors in the weight of rice and the type of container used is very limited.
