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

(1)Core Forming: Fiber reorganization and densification through mechanical extrusion is a key step in converting wet wood chips into pellets. The core principle is "high-pressure extrusion + wood fiber self-bonding." Lignin (a natural adhesive that softens under pressure and frictional heat) in the wet wood chips works together with water to tightly bind the fibers, forming pellets with a fixed shape.

(2)Core component: the forming machine—the "ring die pellet machine," which is more adaptable to wet materials and less prone to clogging.

During the extrusion process, intense friction between the sawdust and the inner wall of the die and the surface of the rollers generates frictional heat of 60-90°C. This temperature softens the lignin in the wood chips (the softening point of lignin is approximately 70-100°C). Simultaneously, the water forms "liquid bridges" that bind the dispersed fibers together, providing a foundation for subsequent shaping.

2.Characteristics of wet wood chips biomass pellet processing equipment

(1)High efficiency and energy saving: For example, pellet machines have low energy consumption, high output, compact process, small footprint, good dust removal effect, low noise, and a good production environment. A production line only requires 2-3 workers and can be operated automatically, reducing labor costs.

(2)Low maintenance cost and easy operation: Wood pellet machines have low maintenance costs and do not require grease injection. Non-professionals do not need much time to complete maintenance. The wearing parts are practical and durable. The roller bearings are made of international brands and are not easy to damage. They are easy to operate and do not require professional operation. 

(3)Raw material processing and environmental protection are taken into consideration: The moisture content of the raw materials before pellet processing needs to be controlled at about 10-15%. Therefore, drying equipment may be required in actual production. Wood pellets contain few harmful substances and the content of harmful gas components during combustion is extremely low. The ash after combustion can be used as potash fertilizer, which meets environmental protection requirements.

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

(1)Biomass power generation/heating enterprises

Typical scenarios: Biomass power plants and industrial boilers (such as heating boilers in textile factories and food factories) require a large amount of stable pellet fuel

(2)Small and medium-sized heating/drying users

Typical scenarios: Rural heating stations, agricultural product drying plants (such as grain, fruit and vegetable drying), greenhouse heating; processed pellets are directly stored in the silo of the heating station and can be taken out as needed.

(3)"Self-circulating" processing in orchards/tea gardens

Typical scenarios: After being processed into pellets, they can be used as fuel for the orchard's "biomass hot air furnace" (for fruit tree frost protection and fruit drying), or crushed and buried in the soil to improve soil quality, realizing "self-circulating waste in the park";

(4)Environmental protection and solid waste treatment fields

Typical scenarios: Urban solid waste treatment plants (sorted wet wood waste), garden waste treatment stations (wet branches, wet shrub slices)

TONY Brand 36-45Ton/Hour Wet Wood Chips Pellet Manufacturing Plant can take wet wood chips, various types of wood - related biomass materials, such as wood pallets ,branches, wood logs, and wood shavings.

The wet wood chip pellet project is a promising biomass energy utilization project.

1. Project Overview:

The wet wood chip pellet project converts wet wood chips generated during wood processing into high-density, high-calorific value wood pellet fuel or biomass pellet products through a series of processes, including crushing, drying, and pelletizing. These pellets can be widely used in biomass power generation, industrial boiler fuel, and residential heating.

2. Market Demand:

(1)Energy Sector: With the increasing global demand for clean energy, wood pellets, as a renewable biomass fuel, are increasingly being used in biomass power generation and industrial boilers. For example, in Europe, wood pellets have become a key fuel for power generation. The German wood pellet market has an annual demand of over one million tons and is growing at approximately 5% annually.

(2)Construction and Furniture Industry: Wood pellets can also be used as a filler in new building materials and furniture production. They are environmentally friendly, energy-efficient, and offer excellent performance. With the development of the construction industry and growing consumer demand for eco-friendly furniture, market demand is also expanding.

Biomass pellets (i.e., wood pellets) processed from wood chips are a clean, renewable biomass energy product. Their energy advantages are primarily reflected in their high calorific value, easy combustion, and strong stability.

1.High density + high calorific value, high energy efficiency

After compression and pelletization, wood chips are significantly reduced in volume (density can reach 1.1-1.3 tons/m³, 4-5 times that of loose wood chips), while their energy density per unit volume is significantly increased (lower calorific value is approximately 4200-4800 kcal/kg, close to that of medium-quality coal). Heat release is concentrated during combustion, resulting in a thermal efficiency 30%-50% higher than directly burning loose wood chips. This makes them suitable for applications with stable heat demand (such as industrial boilers and biomass power generation).

2.Complete combustion and low pollutant emissions.

Wood pellets have a uniform structure and controllable moisture content (dried to 10%-15% during processing). They are not prone to charring during combustion and contain no harmful elements such as sulfur and phosphorus. Exhaust emissions of sulfur dioxide and nitrogen oxides after combustion are extremely low (far lower than those from coal combustion). Dust emissions can also be reduced to meet environmental standards with simple treatment.

3.Convenient storage and transportation, strong stability.

The pellets have a regular shape (mostly cylindrical, 6-10mm in diameter and 10-30mm in length) and good fluidity. They can be transported in bags or bulk, requiring only one-fifth the storage space of loose wood chips. Furthermore, the pellets have a low moisture content and are resistant to mold and mildew. They can be stored for 6-12 months, eliminating the need to worry about raw material deterioration.
