Automatic Biomass Pellet Cooling System counterflow pellet cooler 1-20/T High Efficiency Biomass Pellet Cooler

Automatic Biomass Pellet Cooling System counterflow pellet cooler 1-20/T High Efficiency Biomass Pellet Cooler

DEXI pellet cooler is a core equipment in biomass pellet and feed pellet production, used to rapidly cool and dry newly formed high-temperature pellets. It uses airflow or vibrating screens to evenly dissipate heat, effectively reducing pellet temperature, improving hardness and stability, and preventing deformation or caking. Featuring a compact structure, stable operation, and low energy consumption, it is widely used in biomass energy and feed processing industries, serving as a critical link to ensure finished product quality.

Every part of DEXI machines is strictly quality-checked.

Note: All product specifications can be customized according to customer requirements. If you have any questions,please contact us.

• 1. Industrial and District Heating - Replaces coal in facilities such as factories, schools, hospitals, and centralized heating

networks.

• 2. Power Generation - Serves as fuel in dedicated biomass power plants or enables co-firing with coal in conventional powergeneration.

• 3. Residential Heating - Supplies domestic heating and hot water through specialized pellet stoves and boilers

• 4. Industrial Thermal Energy - Provides a reliable heat source for drying and thermal processes across sectors including foodprocessing, tobacco, and textiles.

Main Advantages - As a renewable energy carrier, biomass pellets offer low emissions, high energy density, and compatibility withautomated handling and conveyance systems, positioning them as a critical enabler of the transition to cleaner energy.

Shandong Dexi Machine Co., Ltd is professional supplier for the biomass pellet machines and complete pellet production line. ourproducts involve, wood chipper, wood sawdust making machine, hammer mill, drum rotary dryer, pellet making machine, pelletcooling machine, pellet packing machine and other related auxiliary equipment.

l ①Chipping:

This stage processes raw logs, forestry residues (branches, trunks), and sawmill waste (bark, offcuts) into 3-5 cm wood chips, preparing the material for subsequent crushing.

l ② Crushing:

The wood chips are further ground into fine sawdust with a particle size of 3-5 mm, achieving an optimal consistency for pelletizing.

l ③Drying:

Excess moisture is rapidly removed from the sawdust. Using a rotary dryer, the moisture content is reduced to approximately13%-the ideal level for pellet formation.

l ④Pelletizing:

The dried material is fed into the pellet chamber, where it is compressed under high pressure into solid wood pellets, typically with diameters ranging from 6 to 12 mm.

l ⑤Cooling:

Freshly extruded pellets exit at elevated temperatures (85-90°C) and require cooling before packaging. A dedicated pellet cooler lowers the temperature to ambient conditions, stabilizing the pellets for handling and storage.

l ⑥ Packaging:

The cooled pellets are automatically weighed and packed into bags of 5-25 kg, followed by stitching or sealing. This final step ensures convenient storage, transport, and market readiness.

l   ⑦Palletizing:

Packed bags are systematically stacked onto pallets to facilitate safe and efficient handing, storage, and logistics.

l  ⑧Film wrapping:

Loaded pallets are securely wrapped with stretch film, ensuring stabiity, protection from moisture and contaminants, and readiness for shipment.

DEXl exports to 116 countries every year, wth over 2,800 equipment solutions delivered globally. Here are one examples from our many successful projects.

Country: Poland

Capacity: 3-5t/h

Raw materials: Wood shavings and Hardwood

After thoroughly evaluating the specific conditions and requirements from our client in Indonesia, DEXI engineered a fully customized wood pellet production line capable of processing 3–4 tons per hour.

The system is designed to efficiently handle raw materials including wood shavings and hardwood from local sawmills. Our integrated solution covers the complete workflow:

• 1. Crushing – uniform size reduction for consistent drying and pelletizing

• 2. Drying – moisture control optimized for tropical climate conditions

• 3. Pelletizing – high-density pellet formation with minimal fines

• 4. Cooling – stable temperature management to ensure pellet durability

• 5. Screening – removal of undersized pellet guarantee product uniformity

• 6. Packaging – automated weighing and bagging for ready-to-market output

Each stage incorporates equipment selected and tuned for the client’s material properties, throughput targets, and site layout. As a result, the plant now consistently produces high-grade wood pellets while achieving a strong return on investment through reliable output and optimized operational efficiency.
