1. The working principle of dried wood log biomass pellet processing equipment

The working principle of dry wood biomass pellet fuel processing equipment is to convert dry wood waste (such as sawdust, shavings, wood scraps, etc.) into high-density, regularly shaped pellet fuel through a series of physical processing steps. The core relies on two major mechanisms: mechanical extrusion densification and natural bonding of lignin, without the addition of artificial adhesives.

2. Characteristics of dried wood log biomass pellet processing equipment

Balance between energy consumption and efficiency, suitable for large-scale production

(1)Dry wood pellet equipment has clear advantages in energy saving and production efficiency:

 Low unit energy consumption: It eliminates the deep drying step (drying energy consumption accounts for 40%-60% of the total energy consumption of biomass pellet processing), and the overall energy consumption is 30%-50% lower than that of equipment that processes wet materials; at the same time, the friction heat generated by dry materials during molding is more concentrated, which can reduce the need for external heating and further save energy.

Strong production continuity: Dry materials are not easy to stick to the inner wall of the equipment (such as the feed pipe and ring die cavity), reducing the downtime and cleaning time caused by material blockage. The continuous operation time of a single pelletizer (1-5 tons per hour) can reach 8-12 hours, which is suitable for large-scale production. 

(2)Automation and safety design Modern dry wood pellet equipment generally has a high level of automation and safety assurance:    

 Intelligent control system: equipped with a PLC control system, which can monitor parameters such as raw material moisture content, feed rate, ring die temperature, and particle density in real time, and automatically adjust the feed speed, roller pressure, etc. to ensure the stability of the finished particle density (1.1-1.3g/cm³) and hardness (crushing strength ≥90%).

 Multiple safety protection: equipped with overload protection (automatic shutdown when the equipment is stuck), temperature warning (starting the cooling device when the ring die temperature is too high), metal detection (automatic discharge when metal impurities are detected in the screening process) and other functions to avoid equipment damage or production accidents. 

(3)Environmental protection and finished product quality assurance : 

 Low pollution emissions: The crushing and screening stages are equipped with dust removal devices (such as pulse bag dust collectors) to reduce the spread of sawdust dust; the pelletizing process does not generate waste gas or wastewater, which meets environmental protection standards. 

Finished product is compatible with combustion equipment: The pellets produced are of uniform size (6-8mm in diameter, 10-30mm in length), do not contain additives, have stable combustion power, and low ash content (≤3%). They can be directly adapted to combustion equipment such as biomass boilers and fireplaces, and are easy to store and transport (high bulk density and not easy to absorb moisture).

3. Application scenarios of dried wood log biomass pellet processing equipment

Professional biomass pellet plants purchase dry wood waste (such as waste from wood processing plants and waste wood from building demolition), process it on a large scale through dry wood pellet equipment, and produce standardized pellet fuel (diameter 6-8mm, length 10-30mm), which is supplied to the following fields:

(1) Industrial heating: used for boiler heating in the textile, food, papermaking and other industries, replacing coal or oil, and meeting the environmental protection policy's requirements for "low sulfur and low nitrogen" emissions.

(2) Civil heating: In Europe, North America and other regions, biomass pellets are the mainstream fuel for home fireplaces and small heating stoves; some northern regions in China are also promoting "coal to biomass". Dry wood pellets have become an important choice for civil heating because of their clean combustion (ash content ≤3%) and easy storage.

(3) Power generation: Large biomass power plants purchase a large amount of pellet fuel, generate electricity through dedicated combustion equipment, achieve renewable energy grid connection, and enjoy national new energy subsidy policies.

Processing dry wood into biomass pellets is indeed a high-quality investment project with both economic benefits and ecological value.

 1. Controllable costs throughout the entire chain, with a short investment return cycle. 

(1) Significant raw material cost advantages:By signing long-term agreements with forest farms and wood processing plants, a stable and low-priced raw material supply can be locked in.

 (2) High cost-effectiveness of equipment investment:The eighth-generation TONY centrifugal high-efficiency pelletizer can achieve an electricity consumption of less than 60 degrees per ton of material, saving 20% ​​energy compared to traditional equipment. 

2. A sound risk prevention and control system and a clear sustainable development path. 

(1) Diversified raw material supply:Investors can use this to build a "mixed pelletizing of agricultural and forestry waste" model to reduce the risk of fluctuations in a single raw material.

(2) Environmentally compliant operations:It is recommended to build a closed raw material warehouse to achieve zero dust overflow and zero sewage discharge. 

(3) Vertical extension of the industrial chain:Combining biomass pellet production with forest tending and forest economy: increasing forest stock through thinning and obtaining residual raw materials from forest tending; using the sawdust ash after pelleting to produce biochar-based fertilizer, achieving the triple benefits of "forestry carbon sink + biomass energy + circular agriculture"
