The manufacture of wood pellet energy is an area of growing interest, on the other hand there is little quality information available on how the process actually works. At first the pellet manufacture process may appear basic plus even straightforward. The fact is this couldn’t be further from the truth, by the fact that to manufacture quality pellets from any raw material requires the raw matter to have definite qualities plus the right apparatus. In a sentence, pellet manufacture is the compression of a loose material into a compressed pellet form by means of a uniform size, shape and density. On the other hand to achieve a pellet of suitable quality will necessitate a deeper understanding of the process of what the raw matter requires to manufacture a quality pellet. Firstly one of the key criteria for biomass pellet manufacture, or any pellet pellet construction is the removal of moisture from the raw matter. There are two reasons for this, firstly as a energy, moisture reduces burning efficiency, temperature generation along with increases ash content. Secondly it is not probable to compress moisture, therefore for the pellet to hold its shape, a low moisture content is vital. Yet a certain percentage of moisture is required for the pellet to form. The percentage of moisture required depends on each raw matter as well as tools used. For instance if steam conditioning is used in the manufacture process, a raw matter moisture content as low as 10% can be used. Yet steam conditioning is generally only used on a large scale through the expensive as well as risk control required. Therefore where steam conditioning is not used, a raw material closer to 15% is required. Too much or too little moisture can consequence wear of the rollers as well as die and also the energy consumption of the pellet mill. Therefore is is generally recommend to experiment by the moisture content of the raw matter to achieve finest pellet quality as well as lowest fuel usage.

Pellet construction can be carried out on either a small or large scale. However as by way of steam conditioning, the gear plus processes used does vary. In terms of drying gear, there are preferences for small in addition to large scale construction based on accessible space, fee, as well as process control. For small scale manufacture, pipe flash dryers are commonly used as they are fairly basic, as well as the cost to manufacturer are fairly low. Vent dryers though are not ideally suited to dry raw materials by a high moisture content around 50%, for example virgin biomass. The raw material may need quite a few passes to remove sufficient moisture. For large scale wood pellet production rotary dryers are used, these are larger plus more expensive, though the drying time can be restricted to dry in a single pass.

There are also differences in the types of pellet mill used in small plus large scale manufacture. The most basic design of pellet mill is the flat die pellet mill. This design is commonly used for small scale production, due to lower manufacture costs along with cheaper consumables. For large scale production ring die pellet mills are more commonly used as they are generally regarded as being more energy efficient. All pellet mill designs share similar principles of operation. These include a roller in addition to die configuration. The design of the pellet mill may either have the die or roller shell rotating, the rotation speed required changes.
