Types of wood pellet coolers
Effective cooling is the primary purpose of a wood pellet cooler for sale, but it also prepares the wood pellets for packaging and storage. Many wood pellet coolers incorporate different techniques, such as air, water, and air-water coolers, are available on the market.
- Air cooler: An air wood pellet cooler uses ambient or forced cool air to reduce the temperature of the freshly produced pellets. It is the most common type of cooler manufactured. The wood pellets are cooled here by exposing them to ambient air. This process is handled by a grate or perforated plate that allows air to pass through. The speed of the air circulation determines how fast the temperature of the wood pellets drops.
- Airflow cooler: It is similar to an air cooler, but a fan is integrated into the system to increase the airflow volume.
- Air-Water Coolers: This type of cooler utilizes both air and water for the cooling process. In this cooler, the wood pellets are first cooled using air, and then they pass through a water bath, which further reduces their temperature.
- Water cooler: A water wood pellet cooler uses water to cool the pellets. It often consists of a cooling jacket or bath where the pellets are submerged or sprayed with water. Water coolers have better cooling rates than air coolers, and they also reduce the risk of fire hazards.
- Rotary cooler: It is a combination of an air and water cooler. In this type of cooler, the wood pellets are cooled by forced air and also sprayed with water from a spray nozzle. The rotary cooler is a large drum that rotates slowly like a cement cooler.
- Drum cooler: The rotary cooler and drum cooler are the same. The freshly produced hot wood pellets are introduced to the cooler's rotating drum, where they are in a constant motion. In the process, the ambient room air circulates, which cools down the wood pellets. The final product is then discharged from the cooler.
- Vibrating coolers: The vibrating cooler works almost the same way as the drum cooler. Here, the cooled wood pellets are separated by vibration rather than rotation. The vibrating cooler has a simpler and more compact design, which makes it a more popular option for small-scale wood pellet manufacturers.
Specifications and maintenance of a wood pellet cooler for sale
Specifications
- Cooling capacity: The cooling capacity indicates the quantity of wood pellets the cooler can handle within a specific timeframe. It is generally expressed in kilograms per hour (kg/h) or tons per hour (t/h).
- Cooling method: There are two primary ways to cool wood pellets: air cooling and water cooling. Coolers that use air flow as a medium are generally more compact and widely applicable but may have slower cooling speeds. Water-cooling wood pellet coolers have faster cooling speeds but may require more complex equipment and maintenance.
- Dimensions: The dimensions of a wood pellet cooler include length, width, and height. Dimensions may vary based on the cooling method and design.
- Weight: The weight of the wood pellet cooler is related to the materials and components used. A heavier cooler tends to have a more rugged construction and better stability.
- Fan power: For air coolers, the power of the fans installed is also a specification. Fan power is usually expressed in watts (W) and is related to the cooling efficiency and noise level.
Maintenance
- Regular inspection: Users should schedule regular inspections of the wood pellet cooler after installation and the first maintenance. Check whether the fasteners in each part are firm, inspect the sealing performance, and check the operation of the cooling fan.
- Cleaning: Clean the wood pellet cooler. Remove the dust and dirt on the cooler body, fan blades, and air outlets. If the cooler is air-cooled, the cooler may need to be cleaned more frequently to ensure proper ventilation and cooling performance.
- Lubrication: Regular lubrication of bearing components and transmission systems is required to ensure the smooth operation of the wood pellet cooler. Use the appropriate lubricating oil or grease onto the bearings and transmission parts.
- Fan maintenance: Maintain the cooling fan. Check the tightness of the blades and the bearing's conditions, ensuring that they are not deformed or worn. If there are any issues, users need to repair or replace them in time.
- Pay attention to the noise and heat: During use, pay close attention to the cooler's working noise and temperature. If found the noise becomes more prominent or the temperature rises abnormally, it needs to be checked and addressed as soon as possible to avoid potential safety hazards.
Scenarios of wood pellet cooler for sale
The wood pellet cooler is an essential part of the wood pellet production line, with relevant application scenarios as follows:
- Wood Pellet Plant: In large or medium-sized wood pellet plants, wood pellet cooling is an integral part of the entire production process. Wood pellets are produced by high-temperature granulators, and excessive heat may cause abnormalities in the subsequent links and storage. Using a wood pellet cooler can lower the temperature of the wood pellets and make them suitable for storage and further processing.
- Biofuel Processing Plant: Biofuel processing plants usually use biomass raw materials to produce various types of biofuel. In the biofuel processing plant, a wood pellet cooler is a necessary facility. It ensures that wood pellets meet the specifications of storage and combustion, improving the quality and utilization of biofuel.
- Pallet Storage: Wood pellet cooling is also necessary when storing wood pellets in warehouses. Wood pellet storage can provide appropriate cooling treatment for wood pellets so that the temperature of wood pellets will not be too high, avoiding the risk of self-ignition and ensuring safety.
- Animal feed production lines: In animal feed production lines, various animal feeds are produced, including pellets. Cooling wood pellet coolers can lower the temperature of the pellets to ensure the quality and safety of the feeds. Using wood pellet coolers can improve the competitiveness of products and satisfy the needs of customers.
- Pellet Mill Manufacturing: For pellet mill manufacturers, ensuring the quality of the produced pellets is critical. Wood pellet coolers are needed to regulate the temperature of the pellets and maintain the stability of the pellet mill production process.
How to Choose Wood Pellet Cooler for Sale

Wood pellet cooler for sale Q&A
Q: Why do wood pellets need to be cooled?
A: The wood pellet cooler reduces the temperature of pellets after they are pressed. Hot pellets cannot be stored because they could spontaneously ignite. Furthermore, cooling makes the pellets more solid and reduces breakage during handling.
Q: What is the optimal cooling time for wood pellets?
A: Wood pellets should be cooled for at least 30 minutes to 2 hours. The time may vary depending on the wood pellet cooler's design and the pellets' temperature.
Q: What are a few methods of cooling pellets?
A: The most common methods of cooling pellets are air cooling, pellet cooler, water cooling, and forced air cooling. Among them, air cooling, pellet cooler, and forced air cooling are the most popular methods in pellet plants. The water cooling method is rarely used because it can make the wood pellets lose their integrity.
Q: What is the recommended storage temperature for wood pellets after cooling?
A: Once cooled, wood pellets should be stored at temperatures below 30°C/86°F to minimize the risk of self-ignition and potential hazards.
