Peanut Shell Pellet Press

make peanutshell pelletsBecause of the advantages of zero emission and renewable, biomass energy is been seen as the most promising alternative energy sources in the future. China is a large agricultural country and also the largest country in the output of agricultural waste in the world. About 650 million agricultural production wastes are produced every year in China. Urgent solution is needed to utilize these wastes becomes an emergency.

Why Make Peanut Shell Pellets? Turn “Waste” Into Wealth!

Peanut shell is a byproduct of peanut shell processing. The shell weight is about 25% of the whole peanut. During the peanut processing, 5 million tons peanut shell will be produced per year. Only a small amount is used in manufacturing edible fungi cultivation and chemical raw materials (such as furfural, butyl, ethyl formate, etc). Most of these peanut hulls are treated as rubbish, causing the waste of biomass natural resources.

By granulating the peanut shells into pellets under high pressure and high temperature with a pellet press or pellet mill, these wastes can be turned into premium pellets fuel. This can not only alleviate the environmental burden produced by discarding and burning, but also solve the energy shortage problem.

Making Peanut Hull into Pellets Fuel

In recent years, the planting area of peanut is increasing year by year. At present, the comprehensive utilization of peanut shell has not got large attention and development. The main reason is that its bulk density is light and cannot be transported to the destination far away for processing effectively and economically. In order to reduce the transportation cost, the peanut shells must be compressed and granulated into pellets. Peanut hull pellet press is what we needed for the compressing or granulating.

How to Start A Peanut Shell Pellet Plant?

The bulk density of peanut hull (peanut shell) pellets is quadruple of raw peanut hull. The pelletize processing does not destroy the component of the peanut hull, but improve the content of soluble dietary fiber. When the air humidity is 60%~80%, the peanut hull pellets will absorb moisture. When the humidity is around 50%, the pellets will loss moisture. When the moisture content of the peanut hull pellets are over 13.7%, they are difficult to preserve.

How The Moisture Content And Additives Effect The Peanut Hull Pelleting Quality?

GEMCO does a great deal of experimental research to find how the water content and pelletizing additives (palmitin and anthracite) influent the quality of peanut hull pellets (including heat value, ash content, density and appearance). Below is three raw material composition of our pelletizing experiments.

No. Water Content Palmitin Content Anthracite Content
1 11% 5% 1%
2 13% 7% 3%
3 15% 9% 5%

Through these experiments, we come up with an optimal raw material proportion for making peanut hull pellets fuel.

  • Peanut Hull / Shell: 79%
  • Water Content: 11%
  • Palmitin: 5%
  • Anthracite: 5%

For the premium pellet fuel, the heat value is higher than 17.5MJ/kg; the anti-crush rate is large than 98%; the density is larger than 650kg/m.
