Making biomass pellets is a process which can be achieved on both a large as well as small scale. As by means of most industries, the development of large scale wood pellet plants presently dominates the biomass pellet production market. Yet, there is a growing number of biomass pellet machines accessible for even small home owners to use to make there own pellet energy. However there is very little information accessible on which wood pellet making machinery is suitable to process different wood materials for fuel pellets.
The first intended use of the pellet appliance was to produce a superior animal feed. The idea was to process the grasses, straws, vitamins as well as minerals into pellet form. The advantages of such were that it would be much cheaper to transportation the feed, much easier to get the animals to take the required mineral plus vitamins as well as eat the correct amount of food to achieve the top charge to profit ratio.
Though, the type and design of pellet machinery used form making animal feed, is not the same type of pellet appliance that can be used for making a wood pellet. Wood as a raw matter is very dissimilar to straws in addition to grasses. Wood has a much higher density along with stronger fibers. These differences mean biomass performs very differently in the pellet machine. To compress a material into a pellet requires sufficient heat plus pressure to melt the materials unrefined lignin.
Through the increased density of wood, means that biomass has to reach a higher heat than grasses and straws to form a pellet. Also, through the increased density of the biomass, more power is needed to compress the biomass owing to the die template in the biomass briquette making machine. This generally means the pellet machinery needs to be geared down to provide more torque.
Not all biomass pellets are the same, depending on the type of wood residue used to manufacture the pellets the ash content of the pellets can change. For case, to create a pellet with as little ash as potential, practically all bark must be removed from the pellets. In many cases on the other hand, this is not practical, in addition to also bark contains a lot of energy. When making a biomass pellet, before placing the matter into the machine, it is very important to monitor the moisture content and manufacture sure it is dry sufficient but still have enough moisture to melt the untreated lignin to help bind the biomass pellet together.
