Pellet molding apparatus

According to the present invention, since the rotary dice and the plurality of roller mills are respectively directly and actively rotated at high speed through a plurality of low-power drive motors, the compression ratio of the pellet raw material can be greatly improved, thereby reducing the manufacturing cost and pellet productivity. The present invention relates to a pellet molding apparatus, which can be greatly improved and furthermore, pellet materials can be evenly supplied to each molding space of the chamber.

There is a need to develop a pellet manufacturing apparatus using wood and recyclable combustible environmental by-products as energy that can cope with fossil fuels such as oil and gas.

Accordingly, in order to secure stable demand for wood pellets, we have been promoting the combustor supply business of wood pellet boilers and stoves. By 2014, about 17,000 home boilers and 67 industrial boilers have been supplied.

Currently, the domestic pellet market started to spread the supply of residential wood pellet boilers and industrial pellet boilers starting in 2009, and it is rapidly growing despite the short market period due to the low cost and high efficiency aspect compared to chemical fuels. In addition, the market began to be formed as a substitute fuel for chemical fuels, mainly in the farming industry, but the scope of application of the pellets is expanding along with the expansion of rural housing and the revitalization of camping culture.

In 2012, domestic wood pellet consumption was 174,000 tons, which was more than three times higher than 63,000 tons in 2011, leading to supply.In the case of wood pellets, 80% of the consumption is imported. Relying on it, it is seeking ways to deal with it.

According to the Japan Wood Pellet Association, world consumption of wood pellets in 2010 increased to 16 million tons to 30 million tons in 2015, and will grow to 59 million tons by 2020.

The Forest Service is forecasting domestic consumption of 5 million tons by 2020 and 4 million tons of imported domestic products, with 1 million of domestic production. Based on these criteria, the domestic consumption market is expected to reach an annual average of more than 800 billion won.

On the other hand, in recent years, farmers can produce pellets that can be used as fuel by using livestock manure, which can be used as a variety of fuels. Patent No. 10-1243471 has been proposed.

However, in the case of Korea Patent Publication No. 10-1243471, by rotating a rotary shaft vertically installed in the center of the die block through a single motor to passively rotate the rolling press formed radially in the die block at regular intervals. Compressing the pellet raw material can not improve the compression ratio of the pellet raw material of the rolling press, as well as the use of one high-power motor to passively rotate the rolling press to increase the manufacturing cost and also reduce the pellet productivity have.
