Chippers are essential machines in biomass processing, converting large woody materials like branches and logs into smaller, uniform chips. This size reduction helps in the efficient drying and further processing of biomass materials.
These machines enhance the surface area of woody biomass, creating standardized particles that are easier to handle, transport, and process. This uniformity ensures consistent quality in the final biofuel product.
Wood chippers are used for a wide variety of applications, such as to create mulch, produce wood pulp, dispose of waste, use wood waste as a biofuel in boilers, use wood waste for making briquettes or pellets, etc.
Biomass Wood Chippers are available in various sizes, from portable garden units to industrial-scale machines. Chippers improve biomass handling efficiency and enable better resource utilization by processing materials that might otherwise go unused.
Dryers play a very important role in biofuel production, as the controlled moisture content plays an important role in the formation of briquettes and pellets, i.e., 8-15%. Keeping moisture levels in control helps to maintain the fuel quality by ensuring the highest burn ratio. Mainly, there are two types of dryers available for biomass drying applications: flash dryers and rotary dryers. The choice of dryer depends on the moisture content and raw material size. For powdery material and low moisture content flash dryers are used, and for bigger size material with high moisture content, rotary dryers are used.
Key Features of Dryers
The cow dung log-making machine is a specialised machine that turns semi-solid cow dung into square- or round-shaped logs. These logs can be used for heat generation for domestic and industrial purposes. It shows a new way to deal with waste and make energy that won’t run out. Ecostan CDL 5 machine can produce up to 450 kg of fuel per hour.
The pneumatic stone separator plays a key role in maintaining the quality and safety of biomass processing. As biomass contains many different types of contaminants like stones, pebbles, metals, and other heavy objects, if not segregated, it can damage the biomass machinery. These contaminants can be separated from the biomass with the help of a pneumatic stone separator. This cleaning step is essential to protect downstream processing equipment from harm and to ensure the final biofuel product remains pure.
