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

Equipment for processing wet wood biomass pellets (i.e., pellet forming equipment for high-moisture wood feedstock) must address the molding difficulties caused by excessive moisture content. Its principles and characteristics differ significantly from those used for processing dry wood. The key to processing wet wood biomass pellets (typically with a moisture content exceeding 30%, and even reaching 50%-60%) is the synergistic effect of drying and mechanical compression to overcome the molding barrier caused by high moisture content, ultimately producing dense pellets.

2. Characteristics of wet wood log biomass pellet processing equipment

(1) High degree of automation, reducing manual intervention

The PLC control system is used to link the crushing, tempering, molding, cooling and other links, and automatically adjust the feed amount, pressure wheel speed and other parameters according to the moisture and hardness of the raw materials, reducing production interruptions caused by fluctuations in the characteristics of wet materials.

Equipped with an automatic mold cleaning device, when the mold is detected to be blocked, it can automatically reverse the pressure wheel or spray a release agent to reduce the frequency of shutdowns for cleaning.

(2) Balance between energy consumption and adaptability, taking into account both efficiency and cost

Compared with equipment that processes dry materials, wet material processing equipment consumes slightly more energy (because it needs to overcome the viscosity and moisture resistance of the wet material), but it eliminates the need for a separate drying step (or significantly reduces drying energy consumption), and the overall energy consumption may be lower (especially when the moisture content of the raw materials is extremely high).

It has strong adaptability to raw materials and can not only process wet wood, but also mix and process other high-moisture biomass (such as straw, sugarcane bagasse, etc.), making it suitable for small and medium-sized processing plants with complex raw materials.

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

(1) Energy and fuel fields

This is the main application scenario. The processed pellets (called "biomass pellet fuel") can replace coal and natural gas and be used in industrial boilers (such as heating in food factories and chemical plants), civil fireplaces (home heating), and biomass power plants (power generation and grid connection).

Advantages: High combustion efficiency (calorific value of about 4000-4800kcal/kg, close to medium-quality coal), low pollutant emissions (SO₂ emissions are only 1/10 of coal).

(2) Agriculture and animal husbandry

Aquaculture bedding: The pellets have strong water and moisture absorption (each kg can absorb 2-3kg of water) and are soft in texture. They are often used as bedding in chicken houses, pig houses, and pet cages. They can reduce ammonia emissions and improve the breeding environment.

Organic fertilizer raw materials: After being crushed, the pellets can be mixed with livestock and poultry manure for fermentation to make organic pellet fertilizer, which can be used in farmland and orchards to improve soil fertility.

TONY Brand 18 Ton/Hour Wet Wood Log Pellet Manufacturing Plant can take wet wood, various types of wood - related biomass materials, such as branches, small - diameter logs, and wood shavings, with wet wood as the main raw material. After pretreatment and processing, it is solidified into high - density wood pellet fuel. This fuel is an ideal substitute for coal and oil and plays a role in energy conservation and emission reduction. At present, it has been widely used in regions rich in wood resources.

Project Site Selection and Construction Plan

1.Project Site Selection

(1)Resource Advantages: The project site is surrounded by numerous wood processing plants, furniture factories, and other businesses, providing a rich source of wood processing residues, ensuring a stable supply of raw materials. Furthermore, the abundant local forestry resources provide a solid foundation for the project's long-term development.

(2)Convenient Transportation: The site is located near major transportation arteries and boasts a well-developed road and rail network, facilitating the import and export of raw materials and products, effectively reducing transportation costs.

(3)Well-Developed Infrastructure: The area has comprehensive infrastructure, including water, electricity, and communications, to meet the needs of project construction and production operations. Furthermore, the local government has provided a series of preferential policies and a favorable business environment to attract investment, facilitating the smooth implementation of the project.

2.Construction Plan

(1)Production Workshop: The modern production workshop features a steel structure with wide spans and high ceilings, facilitating equipment installation and production operations. The workshop is rationally laid out according to the production process flow, with functional areas such as raw material storage, pretreatment, crushing, drying, pelletizing, cooling, screening, and packaging to ensure a smooth production process. Raw Material Warehouse and Finished Product Warehouse: Separate warehouses will be built to store raw materials and finished products. These enclosed warehouses feature excellent ventilation, moisture-proofing, and fire-proofing to ensure the quality and safety of raw materials and products.

(2)Office and Living Area: A comprehensive office building will be used for daily office work and management.

(3)Environmental Protection Facilities: To minimize the environmental impact of the project's production processes, comprehensive environmental protection facilities will be constructed. These include the installation of efficient dust removal equipment to collect and treat dust generated during production, ensuring that exhaust emissions meet emission standards; sewage treatment facilities to treat wastewater generated during production to meet national emission standards; and dedicated solid waste storage areas to collect and properly dispose of solid waste, including slag, generated during production.

Wood pellets are standardized biomass fuels made from wood processing waste (such as wood chips, sawdust, shavings, and branches) that are crushed, dried, and compressed.

 1.They have stable physical properties. 

They have a regular shape: most pellets are cylindrical, 6-12mm in diameter and 20-50mm in length, with a density of 0.8-1.2g/cm³. They are hard and resistant to breakage, making them easy to store and transport.

They have a low moisture content: They undergo a drying process before molding, typically keeping the moisture content at 10%-15%. This reduces charring during combustion and ensures stable thermal efficiency.

2.Their composition and combustion characteristics are tailored to energy needs. 

They are primarily composed of lignocellulose, which contains approximately 45%-50% carbon. They have a high calorific value (typically 4200-4800 kcal/kg, similar to medium-quality coal) and burn efficiently.

They have an extremely low sulfur content (typically <0.05%) and low nitrogen content. Pollutants such as SO₂ and NOₓ produced during combustion are far lower than those produced by coal, meeting environmental standards. 

3.The raw materials are widely available and renewable. 

The raw materials are wood processing waste (such as scraps from furniture and panel mills) and forestry waste (such as pruned branches and fallen leaves). This represents a "waste-to-treasure" resource recycling effort, without requiring additional arable land or forest resources.
