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

(1)Pre-treatment: "Homogenization" of wet wood chips

Wet wood chips (such as wood processing waste, construction waste wood chips, etc.) usually have problems of uneven size and humidity fluctuations. They need to be adjusted to a state suitable for molding through pre-treatment to avoid subsequent blockage or molding failure.

(2)Core molding: "Fiber reorganization and densification" under mechanical extrusion

This is the key step in converting wet wood chips into pellets. The core principle is "high-pressure extrusion + wood fiber self-bonding" - the lignin in the wet wood chips (a natural adhesive that softens under pressure and frictional heat) works together with water to make the fibers tightly bonded to form pellets of fixed shape.

(3)Cutting and shaping: "Precise control" of pellet length

The wet wood chips squeezed out of the mold forming hole will form "continuous cylindrical strips" that need to be cut into pellets of uniform length by a cutting mechanism. 

(4)Cooling and screening: the final checkpoint for pellet quality

(5)Auxiliary systems: ensuring stable operation of the equipment

Wet wood chip pellet processing equipment requires auxiliary systems to solve problems such as "blockage and overload" during wet material processing. The core systems include electronic control systems, dust removal systems, and lubrication systems.

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)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 wet wood chip pellet processing projects:

The core drawbacks of wet wood chips are their high moisture content, high transportation costs, and susceptibility to deterioration. Traditional disposal methods (landfill and incineration) require fees. This project effectively transforms these into raw material advantages:

1. Extremely low raw material costs, even negative costs

Wet wood chips are mostly waste from wood processing (furniture factories, plywood factories), forestry harvesting (tree branches/tailings), and building demolition (waste timber). Most companies have to pay for their removal and disposal. Project owners not only avoid purchasing these, but can even charge a "waste disposal fee" in some cases.

Compared to "dry wood chip pellet processing," wet wood chip raw material costs are directly reduced by over 80%, significantly reducing the total project cost.

2. Wide range of raw material sources and strong regional adaptability. 

As long as there are areas with wood processing, forestry, construction, and landscaping activities, there will be a stable supply of wet wood chips (such as furniture industry clusters, areas surrounding forest farms, and urban demolition sites). This eliminates reliance on a single raw material source and eliminates the "raw material competition" (dry wood chips must compete with industries like papermaking and wood-based panels, while wet wood chips have no other high-value uses), ensuring long-term raw material stability.

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 wet 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.
