EFB Pellet Machine

The EFB Pellet Machine is an environmentally friendly machinery, which is specifically designed to convert EFB into high-density, uniformly shaped biomass fuel pellets.

Core Definitions of EFB Pellet Machine

EFB pellet machine is a granulation machine specifically designed to address the issue of waste from palm oil mills.

EFB stands for Empty Fruit Bunch, which is the main agricultural waste produced by palm oil mills after the extraction of palm oil. These waste materials are difficult to process, occupy a lot of space when piled up and they are prone to causing environmental problems. Moreover, EFB fibers are long and have a loose texture, which is difficult to utilize in their natural state.

However, the EFB pellet machine is not only a machine but also a crucial component in realizing the circular economy of the palm oil industry. Through specialized technology, it transforms agricultural waste into economically valuable green energy and products, which greatly reduces environmental burdens and creates new sources of income. This holds immense significance for palm oil-producing nations, where the EFB pellet machine brings substantial economic and environmental benefits.

RICHI Machinery’s EFB Pellet Machine features advanced design and production configuration, with compact structure and excellent performance. In addition to processing EFB pellets, this EFB pellet machine can also pelletize materials that are difficult to process with low adhesion rates, such as rice husks, sunflower seed shells, peanut shells and stems, bark, and other biomass waste. Additionally, we can customize EFB pellet plant to meet your specific production requirements.

How Does a EFB Pellet Machine Work?

The working principle of the EFB pellet machine involves the physical process of high-temperature, high-pressure compression to compulsorily reshape loose and unformed EFB fibers into high-density, uniformly shaped solid fuel pellets. The entire conversion process can be divided into four stages.

Feeding: The crushed EFB fibers are uniformly fed into the pelleting chamber through the feeder.
Conditioning: During this process, steam is injected to condition the fibers, which makes them softer and more flexible. Simultaneously, the temperature is raised to facilitate subsequent forming.
Forming: Under the powerful pressure of the press rollers, fibers are forcibly squeezed through the cylindrical channels of the ring die. During this process, the material becomes extremely dense.
Cutting: As the compressed material is extruded from the opposite end of the die hole, the cutting blades that are installed on the outside of the die will cut it into predetermined lengths, which forms the final pellets.

Why Produce EFB Pellets?

The fundamental purpose of producing EFB pellets lies in transforming agricultural waste into highly valuable resources. This approach not only resolves the most urgent waste disposal challenge of the palm oil industry by converting it into clean energy and economic benefits, but also significantly promotes the green and sustainable development of the new energy sector.

Waste Management

Palm oil mills generate substantial amounts of empty fruit bunch waste during production. This waste is bulky and occupies large areas. If they pile up randomly, they will rot and emit foul odors, attract mosquitoes and other pests, and potentially contaminate water sources and soil.

Reducing Energy Costs

Palm oil mills are major energy consumers themselves. Using self-produced EFB pellets to replace coal or natural gas for providing steam and electricity to boilers can significantly reduce energy purchase costs.

Clean Combustion

Compared to coal, EFB pellets have extremely low sulfur content, which produces minimal sulfur oxides during combustion. Processing them into pellets and burning them cleanly in specialized equipment can significantly reduce pollution emissions.

Abundant Raw Materials

It is very common in Southeast Asia, particularly in Indonesia and Malaysia. Sufficient material can be obtained from oil palm plants, which has abundant material resources.

Supporting Equipment for EFB Pellet Line

If you are interested in mass-producing EFB pellets, we strongly recommend establishing a complete and automated biomass pellet plant. RICHI can provide customized EFB pellet machines and all necessary supporting equipment for your production line. Below is a list of basic supporting equipment for an EFB pellet line for your reference.

EFB Hammer Mill

The original EFB fibers are long and have uneven moisture content, so they cannot be directly compressed. Therefore, a EFB hammer mill is required to cut the long fibers into uniformly short lengths. This reduces fiber entanglement and improves material flowability.

EFB Dryer

A dryer is used to reduce the moisture content of the material to the optimal range of 12%-15%. Adequate moisture acts as a lubricant and weak binder during compression, but excessive moisture generates steam, which causes the pellets to become loose and break apart.

EFB Pellet Machine

The EFB pellet machine processes crushed raw materials into solid fuel. As the core component of the entire EFB pellet line, the EFB pellet mill directly determines the production capacity of the EFB pellet line.

EFB Counter-flow Cooler

Freshly molded pellets are extremely hot and soft in texture. They must be immediately transferred to a cooler for rapid cooling. This cooling process will remove surface heat and some moisture from the pellets, so that they can be hardened and set into shape. This facilitates subsequent storage and transportation.

EFB Automatic Packing Scale

After cooling, EFB pellets can be packed into bags of the required size and stored in a dry location to prevent moisture absorption.
