Description

Powder transfer system {POWDER TRANSFER SYSTEM}

The present invention relates to a powder transport system, and more particularly, to a technology for removing dust generated by transporting the powder of milled grains to a moving tank of a vehicle.

Due to the westernization of the diet, the people's rice consumption has significantly decreased, and the rice stock has increased sharply, resulting in serious problems such as a decrease in the income of rural areas where rice farming is done. To solve this problem, research on methods to promote rice consumption was conducted, and among them, research and development on processed food using rice was intensively carried out.

It is easy to develop food products that use rice as a raw material, rather than using rice grains as they are, by crushing rice and transforming it into rice flour with fine particles. In order to manufacture processed food using rice, the process of pulverizing rice grains to have fine particles and milling them into powder form should be preceded above all.

The powder milled in the grain crushing system is shipped by a vehicle, and a lot of dust is generated by the powder in the transport process for loading the powder into a moving tank of the vehicle. In particular, there is a problem that the dust generated during the transport process has a possibility of causing respiratory diseases of workers, and there is a risk of explosion due to a fire or the like.

The matters described as the background art above are only for improving the understanding of the background of the present invention, and should not be taken as an acknowledgment that they correspond to the prior art already known to those of ordinary skill in the art.
