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

The working principle of dried wood log biomass pellet processing equipment

Dry wood biomass pellet processing equipment operates by converting dry wood waste (such as sawdust, shavings, and wood chips) into high-density, regularly shaped biomass pellet fuel through a series of physical processes. This process relies on mechanical extrusion and the natural bonding of lignin, eliminating the need for additional adhesives. The dry wood biomass pellet processing process can be summarized as follows: raw material pretreatment → extrusion molding → post-processing. Because the raw material is "dry wood" (with a moisture content typically controlled at 10%-15%), deep drying is not required. Instead, the process focuses on densifying the material through mechanical force and utilizing the heat generated during processing to activate the bonding properties of lignin, ultimately forming stable pellets.

2. Characteristics of dried wood log biomass pellet processing equipment

Strong adaptability of raw materials, achieving efficient resource utilization

(1) Wide range of raw material sources: It can process a variety of dry wood waste, including sawdust, shavings, scraps after wood processing, and forestry waste (such as branches, bark, etc.), and can be processed without complex pretreatment, effectively realizing "turning waste into treasure".

(2) Clear requirements for raw material moisture content: Based on the characteristics of "dry wood", the equipment is more suitable for processing raw materials with low moisture content (usually 10%-15%), without the need for additional high-intensity drying (or only simple humidity adjustment), reducing energy consumption and processing costs.

The core equipment (pellet mill) has stable performance and high molding efficiency

(3) Relying on natural adhesives (lignin): The high temperature (100-120℃) generated by extrusion softens and melts the lignin in the wood, without the need to add artificial adhesives, which not only reduces costs but also ensures the environmental friendliness of pellet fuel (no harmful residues after combustion).

(4) High particle density and uniform quality: After high-intensity extrusion between the ring die and the roller, the particle density after forming can reach 1.1-1.3g/cm³. It has high hardness, is not easy to break, and has a regular shape (diameter 6-8mm, uniform length), which is convenient for storage and transportation.

(5) Strong continuous production capacity: Modern pellet mills mostly use automated feeding and speed control systems, which can adjust the speed and pressure according to the characteristics of the raw materials to achieve continuous and stable production. The output of a single device can reach hundreds of kilograms to several tons per hour, meeting the needs of different scales (from home workshops to industrial production).

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

Wood processing plants (such as furniture, wood flooring, and plywood factories) generate large quantities of dry sawdust, shavings, offcuts, and scraps during production. These waste materials have a low moisture content (typically ≤15% after natural air drying) and can be directly processed into pellet fuel through dry wood pellet processing without additional drying, thus achieving a "waste-to-energy" internal cycle:

(1)Self-use energy supply: The pellets produced can be directly used in the factory's heating system (such as boilers and kilns), replacing traditional coal and natural gas, reducing energy costs (biomass pellets are typically 30%-50% cheaper than natural gas) and lowering carbon emissions.

(2)Reduced waste disposal costs: Wood waste can be recycled through processing equipment, eliminating the need for waste accumulation and waste incineration (which can be polluting). Excess pellets can even be sold to generate additional revenue.

TONY Brand 3.5-4 Ton/Hour Dried Wood Log Pellet Manufacturing Plant can take dried wood, various types of wood - related biomass materials, such as branches, small - diameter logs, and wood shavings, with dried wood as the main raw material. After pretreatment and processing, it is solidified into high - density wood pellet fuel.

Biomass pellet venture capital projects have broad prospects. The following is a detailed introduction to the project:

1. Project Advantages

Strong Market Demand: Biomass pellet fuel, due to its low carbon footprint, environmental friendliness, and high calorific value, enjoys significant demand both domestically and internationally. Domestically, the promotion of industrial boiler renovations, biomass heating, and power plant construction has significantly expanded the market. Stringent environmental regulations in Europe and other regions have also led to a surge in demand for biomass fuel, creating new export opportunities for domestic companies.

Various Raw Material Sources: Biomass pellet production can be sourced from a wide variety of agricultural and forestry waste, such as straw, rice husks, peanut shells, sawdust, and wood scraps. These resources are often abundant in rural areas and surrounding areas, and in some areas are even available free of charge, effectively reducing raw material procurement costs.

2. Cost-Benefit Analysis

Cost Investment: Equipment costs vary significantly depending on production volume and configuration. Pellet machines typically cost tens to hundreds of thousands of yuan. Large-scale biomass pellet production lines require significant equipment investment. Furthermore, there are costs associated with raw material procurement, labor, site rental, and operational maintenance. Profit margin: Different types of biomass pellet fuels have different prices, and the return on investment is relatively considerable.

1.High combustion efficiency and a wide range of applications.

Full combustion: The pellets have a dense structure, ensuring uniform air-fuel contact during combustion, a stable flame, and a thermal efficiency exceeding 85% (higher than the 30%-40% of loose firewood), reducing energy waste.

High adaptability: They can directly replace fuels such as coal and natural gas for use in industrial boilers (in the textile, food, and chemical industries), residential heating (fireplaces, biomass heating stoves), and biomass power plants, without requiring major modifications to existing equipment (only burner parameters need to be adjusted).

2.Stable raw material source and manageable costs

Sufficient raw material: They primarily utilize wood processing waste (such as sawdust and shavings from furniture and plywood factories), eliminating the need to consume high-quality wood, effectively turning waste into valuable resources. Raw material procurement costs are low (typically 100-200 yuan/ton, and in some areas, they are even available free of charge).

Low price volatility: Compared to fuels such as natural gas and coal, which are more susceptible to international energy markets, wood pellet prices are more stable. Their predominantly regional supply limits transportation radius, ensuring manageable long-term costs. 

3.Other Features

Easy to Ignite: Low moisture content (typically <10%) allows for fast ignition, and combustion produces no black smoke or odor, providing a superior user experience compared to loose coal and firewood.

Policy Support: As a clean energy source, wood pellets are eligible for national and local subsidies (such as biomass fuel subsidies and energy conservation and emission reduction incentives), further enhancing their economic viability.

In summary, wood pellets, with their environmentally friendly, efficient, convenient, and cost-effective characteristics, have become a valuable alternative to traditional fossil fuels, offering broad application prospects in industrial, residential, and power generation applications.
