Straw Pellet Plant Production Process
Before pelleting, straw should be ground into uniform size of less than 5mm, at this time wood hammer mill can be the best choice.
Straw is often air-dried, with a moisture content of typically 15%. However if the moisture content is higher than 15%, one rotary drum dryer is then necessary.
Straw is pressed into pellets under the pressure of straw pellet mill. Common size for straw is 6mm and 8mm.
After pelleting, straw pellets is with high temperature, so in order to maintain its quality pellets cooling machine is needed.
Use a pellet packing machine to seal straw pellets in bags so that the storage and delivery can be made easier.
Comparison of Crop Straw and Straw Pellets
1. Better combustion features: As we can see from the chart above, straw pellets have higher calorific value, lower moisture content and less ash content, which makes it a fuel with better combustion features.
2.Environmental friendly: On one hand, straw pellets are carbon-neutral which causes zero CO2 emission. On the other hand, the pollution caused by direct burning can be avoided.
3.Economical benefit: Both the potential market of biomass pellets and the high efficiency of straw pellet plant contribute the fast return of your investment.
4.Easy to store and transport: Density of straw biomass pellets is higher, which reduces their storage space and delivery cost.
Application of Straw Pellets
1. Used as fuel for heating or cooking.
2. Used as animal bedding.
3. Used as animal feed.
