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

The dry pallet biomass pellet processing equipment uses waste dry pallets as raw material. Through three core steps: pretreatment, extrusion molding, and cooling and packaging, it transforms the loose wood material into high-density biomass pellets. Its operating principles revolve around "raw material adaptation" and "converting mechanical energy into molding force."

First, in the pretreatment stage, the equipment receives dry pallets through a feed system. A crusher breaks the pallets into wood blocks, which are then further pulverized into wood chips by a grinder.

Next, in the core extrusion molding process, a screw feeder evenly feeds the pretreated wood chips into the pelletizer. Inside the pelletizer, a compression roller and an annular die form an extrusion chamber. A motor drives the rollers to rotate at high speed, forcing the wood chips into the die's molding holes. Within the die, the wood chips are subjected to high temperature and pressure, softening the hemicellulose in the wood fibers and creating bonding forces. Finally, they are continuously extruded into cylindrical pellets.

Finally, in the cooling and packaging phase, the pellets enter a cooler where they are cooled by reverse-blowing cold air, bringing the temperature down to room temperature (to prevent moisture and mildew during storage). The cooled pellets are then screened by a vibrating screen to remove broken, fine particles (which can be returned for re-pelleting). Qualified pellets are then sent to the finished product warehouse for storage or packaging, completing the entire processing process. This entire process recycles waste dry wood pallets.

2. Characteristics of dried wood pallets biomass pellet processing equipment

(1)Wide adaptability of raw materials, achieving "waste resource conversion":It can directly process discarded dry pallet wood (including common pallet materials such as pine, fir, poplar, and miscellaneous wood), eliminating the need for complex sorting (only metal parts need to be removed). This solves the problem of difficult dry pallet recycling and environmental pollution, aligning with the concept of a "circular economy."

(2)Stable pellet quality and excellent fuel performance:Using "ring die-roller" high-pressure extrusion technology, combined with the wood's own lignin bonding, the finished pellets achieve a density of 1.1-1.3 g/cm³, high hardness, and resistance to breakage, making them easy to transport and store over long distances.

The finished pellets have a low moisture content, stable calorific value, and are smokeless and odorless when burned. Pollutant emissions are significantly lower than coal (SO₂ emissions are only 1/10 of coal, and NOx emissions are reduced by over 30%), meeting environmental standards (such as GB/T31740-2015 "Biomass Solid Pellet Fuels").

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

Dry wood pallet biomass pellet processing equipment has a wide range of applications, covering environmental protection and energy needs across multiple sectors. In the industrial sector, the pellets produced can replace coal and natural gas as fuel for boilers and hot air furnaces in the food processing, chemical, and building materials industries, helping companies reduce energy costs and carbon emissions, in line with the "coal reduction and carbon reduction" policy.

In the consumer sector, during the winter heating season in northern China, pellets can be used in household biomass heating stoves, small hotels, and office building heating boilers. Compared to electric and natural gas heating, they are more economical, produce no black smoke, and meet environmental heating needs.

In agriculture, pellets provide a stable heat source for drying grain, fruits, vegetables, and traditional Chinese medicines, with adjustable temperatures and low costs, avoiding agricultural drying pollution. Furthermore, they can be integrated with forestry processing parks to process discarded dry wood pallets and scraps, achieving self-sufficiency and self-distribution of solid waste. In the environmental protection sector, logistics parks, warehousing companies, and municipal solid waste treatment centers can use this equipment to convert discarded dry wood pallets, which would otherwise be landfilled or incinerated, into high-value pellets, reducing environmental burdens, forming a "solid waste-to-resource" cycle, and promoting the resource utilization of wood waste.

The biomass pellet processing startup project is an environmentally friendly venture capitalizing on the dual trends of "solid waste resource utilization" and "clean energy substitution." Using waste wood (such as discarded dry pallets from the logistics industry, lumber mill scraps, agricultural and forestry pruning branches, and furniture production waste) as its core raw material, it utilizes specialized equipment such as shredding, crushing, drying, and extrusion to produce high-density biomass pellet fuel. Suitable for small and medium-sized investors, it offers both economic returns and social value.

 The project's core competitiveness lies primarily in its low cost and high adaptability of the raw material: The raw material is widely sourced, mostly from waste resources, and can be purchased at low prices in logistics parks, furniture factories, and forestry farms. Some partners even provide it free of charge (though transportation costs must be covered). Furthermore, the equipment can efficiently sort and process dry pallets with metal connectors and branches containing impurities through pre-processing, eliminating the need for extensive manual screening and achieving a raw material utilization rate of over 90%. Furthermore, to promote the development of "zero-waste cities," local governments often provide site and equipment subsidies for solid waste resource utilization projects, further reducing initial startup pressures.

 In terms of market demand, the project aligns with the energy structure adjustment needs under the "dual carbon" policy. In the industrial sector, boiler heating in small and medium-sized factories and the drying process in food processing companies require alternatives to highly polluting coal fuels, and biomass pellets can be directly integrated into existing equipment. In the agricultural sector, there is a strong demand for low-cost fuels for winter insulation in greenhouses and heating livestock and poultry farms. In the civilian sector, biomass pellets are becoming a high-quality alternative to coal due to their convenient storage and smokeless combustion in rural areas of northern China. Demand for these products covers multiple scenarios and is growing year by year.

Widely available and low-cost raw materials. Discarded wooden pallets are a common waste material in logistics, warehousing, wood processing, and manufacturing, generating significant quantities annually (e.g., discarded pallets from e-commerce and machinery companies). This raw material eliminates the need to purchase additional wood and can often be recycled at a low price. In some areas, collection is even free (companies are willing to pay for the removal of discarded pallets, even though they need to dispose of them). This significantly reduces raw material procurement costs and ensures project profitability.

1.Raw material pre-processing is relatively easy.

 Wooden pallets are primarily made from common hardwoods or softwoods, such as pine, fir, and poplar. Their fiber structure is intact, requiring no complex sorting (only impurities like nails and plastic need to be removed). They can be directly crushed and processed, resulting in low energy consumption and high efficiency.

2.Strong raw material supply stability.

 The logistics industry has a long-standing demand for wooden pallets, and the generation of discarded pallets has steadily increased with the scale of logistics. By establishing long-term recycling agreements with warehousing companies and manufacturing plants, a stable raw material supply chain can be established, avoiding the risk of running out of material to process.
