Richi Machinery supply ring die peanut shell pelletizer machine and 1-40 ton per hour complete peanut shell pelletizing production line.Because 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.
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 ring die peanut shell pellet press machine or ring die peanut shell pellet mill machine, 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.
2.Making Peanut Hull Into Biomass 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. High efficiency low consumption ce peanut hull pellet making machine is what we needed for the compressing or granulating.
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.
Peanut shell pellets crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials.
Rotary drum drying machine for peanut shell pellets is mainly used for drying the peanut hull pellets with a certain degree of humidity and particle size.
Dual motor driving system, low noise and no need for lubrication, screw feeder adopts frequency converter; Start current is half of single motor gear biomass wood pellet mill for peanut shell pellets,low working voltage. SKF bearing and Siemens motor;Automatic oil adding device for main shaft and roller.
Advanced theory of countercurrent cooling, widely applied in pellet cooler, such as Granulation, Expansion, extruder, expanded and so on.
Belt packing scale is suitable for powder and granular materials, spiral feed scale applies only to powder material.
4.How Moisture Content & Additives Effect Peanut Hull Pelleting Quality?
Richi Machinery 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.
(1)NO.1 peanut hull pellets
(2)NO.2 peanut hull pellets
(3)NO.3 peanut hull pellets
Through these experiments, we come up with an optimal raw material proportion for making peanut hull pellets fuel.
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.
