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

The process of processing dry wood chips into pellets is essentially a process of "raw material adaptation → physical shaping → stable shaping". Three key stages determine the quality of the pellets:

(1) Raw material pretreatment: Make the dry wood chips meet the "extrudability"

The initial state of the dry wood chips (particle size, moisture content) directly affects the molding effect. The core of pretreatment is to solve two problems

(2) Extrusion molding: Rely on "friction heat + pressure" to achieve bonding

This is the core link of the entire equipment. The principle can be summarized as "pressure compaction + lignin bonding"

(3) Cooling and shaping: Make the pellets maintain "structural stability"

There are two problems with freshly extruded pellets: ① The temperature is high (80-100℃), and the lignin is not completely solidified; ② A small amount of hot air may remain inside. If stored directly, it is easy to cause: the pellets to stick to each other (lignin has not cooled and hardened); the hot air inside shrinks when it cools, causing the pellets to crack; high temperature accelerates moisture absorption, increasing the risk of mold. Therefore, the cooling system uses "air cooling + vibrating screen" to quickly cool down (to room temperature) and release the internal stress of the particles, ultimately forming biomass particles with "high hardness (compressive strength ≥ 150N), no agglomeration, and easy storage".

2. Characteristics of dried wood chips biomass pellet processing equipment

(1) Automatic lubrication and intelligent control: The pellet machine is equipped with an automatic lubrication system and variable frequency speed regulation function, which can adjust the speed according to the characteristics of the raw materials, avoid machine blockage problems, and reduce energy consumption. 

(2) High efficiency and energy saving and cost control Dry-in and dry-out process: When the moisture content of the raw materials is 10-15%, there is no need to dry them and they can be processed directly, which significantly reduces energy consumption costs. Low maintenance design: The equipment's vulnerable parts (such as molds and rollers) are made of high-strength materials. Combined with regular lubrication and maintenance (such as gear oil replacement and metal impurity cleaning), they can extend their service life and reduce downtime.

(3) Environmental protection and resource recycling Zero additives and pollution-free: The processing process does not require adhesives and relies on the softening and bonding of lignin itself. When the finished product is burned, there is no harmful emission such as sulfur dioxide, which meets the requirements of energy conservation and emission reduction. Waste resource utilization: Agricultural and forestry waste such as dry wood chips and waste wood can be converted into high-value pellet fuel, realizing "waste to treasure" and contributing to the circular economy.

(4) Application scenarios and market adaptability: The equipment is widely used in industrial boilers, biomass power plants, civil heating and other fields. With the advancement of environmental protection policies, equipment is extending from traditional energy replacement to diversified fields such as feed and fertilizer, and market demand continues to grow.

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

(1) Building materials industry: Wood chips can be used as raw materials for building materials and used to produce various boards and composite materials.

(2) Furniture factories: During the furniture manufacturing process, scraps and leftovers can be converted into wood chips through wet wood chip processing equipment. These pellets can be reused or used as fuel.

(3) Forestry and board mills: Wood waste generated in these places can be processed into wood chips for the production of biomass energy.

(4) Animal husbandry and feed industry: Wood chips can also be used as raw materials for feed pellets. After proper drying and processing, they can meet the needs of animal feed.

Raw Material Advantages of Dry Wood Chips for Biomass Pellets

Dry wood chips, as the core raw material for this project, offer the advantages of a wide range of sources, low cost, and easy storage. This fundamentally addresses the pain points of biomass projects, often associated with raw material shortages and price fluctuations:

1. Wide-ranging and stable raw material sources

Major sources include: wood processing plant scraps (such as sawdust and wood chips), forestry logging residues (such as branches and trunk segments), fruit tree pruning branches (such as waste branches from apple and pear orchards), and waste from wood-based panel manufacturers. In regions with abundant timber resources (such as the forested areas of Northeast China, Southwest China, and East China), the raw material collection radius can typically be controlled within 50 kilometers, resulting in low transportation costs and year-round supply with no significant seasonal fluctuations (dry wood chips with a moisture content of ≤15% can be stored for long periods).

2. Low raw material cost, reducing production costs

The purchase price of dry wood chips is significantly lower than that of raw materials such as straw and rice husks. Some wood processing plants even provide them free of charge (only the transportation costs are covered) to process the waste. This offers significant profit potential. 

3. Simple raw material pretreatment, requiring no additional investment.

Dry wood chips are inherently low in moisture and easy to crush (typically 10%-15% moisture content, requiring no additional drying). They are 5-10mm thick, and can be crushed into 3-5mm wood powder using a standard hammer mill. Compared to straw, which requires prior sun drying and impurity removal, pretreatment equipment and energy costs are reduced by 30%-40%.

1. Outstanding environmental value: renewable, low-carbon, and contribute to "dual carbon" 

(1) 100% renewable, recycling resources The raw materials mainly come from wood processing waste (such as wood chips, sawdust, scraps), forestry residues (such as branches, bark), without consuming natural timber, realizing the "waste-to-treasure" of agricultural and forestry waste, avoiding the methane (strong greenhouse gas) generated by the accumulation and decay of waste or the pollution caused by incineration, and promoting the recycling of resources. 

(2) "Carbon neutral" emissions, in line with low-carbon goals The carbon dioxide released by the combustion of wood pellets is basically balanced with the amount of carbon dioxide absorbed during the growth of trees. From the perspective of the life cycle, it is a "carbon neutral" energy source and can replace fossil energy such as coal and oil, helping to reduce carbon emissions in industries such as industry and heating, and is in line with the global "dual carbon" strategy and the environmental protection policy orientation of various countries. 

2. Good economic efficiency: controllable costs and policy support

(1) Low raw material costs and stable supply

The raw materials are wood processing waste or forestry residues. The procurement cost is much lower than coal and natural gas. The raw materials are widely sourced (furniture factories, wood processing plants, forest farms, etc.). The supply chain is stable and there is no need to worry about raw material shortages.

(2) Obvious production and use cost advantages

Although the pelletizing process requires equipment and energy consumption, the high calorific value and high transportation efficiency of the pellet products can offset some of the costs. For example, under the same heat demand, the cost of using wood pellets is 20%-30% lower than natural gas and 40%-50% lower than electric heating, which is attractive to both businesses and households.
