As the core equipment for the industrialization of biomass energy, the biomass pellet machine has become the "key pusher" for promoting the large-scale application of renewable energy by virtue of its efficient conversion ability of agricultural and forestry waste. Its role is not only reflected in the technical level of raw material conversion, but also by solving the pain points of "dispersion, inefficiency, and non-standard" of biomass energy, it has opened up the whole chain from agricultural and forestry waste to large-scale clean energy

1. Solve the problem of "dispersion" of raw materials and lay the foundation for large-scale supply

Biomass raw materials (straw, wood chips, etc.) naturally have the characteristics of "dispersed distribution and low density" (such as the natural stacking density of straw is only 80-120kg/m³, and wood chips are about 100-150kg/m³), which directly leads to the collection, transportation, and storage costs accounting for more than 40% of the total cost, becoming the primary obstacle to scale.

The biomass pellet machine compresses the raw materials into pellet fuel with a density of 1.1-1.3g/cm³ (i.e. 1100-1300kg/m³) through high-temperature extrusion molding, and the density is increased to 5-10 times that of the raw materials:

Transportation efficiency: The loading capacity of the same transportation tool is increased by more than 5 times

Storage capacity: Pellets can be stacked and stored (up to 3-5 meters in height), occupying only 1/8 of the raw materials (100 tons of pellets require a 100㎡ warehouse, while the same raw materials require 800㎡), and the moisture resistance is improved, and the storage period is extended from 1 month of raw materials to 6-12 months.

This "high-density conversion" capability allows scattered agricultural and forestry waste to be centrally processed through the "village collection point-regional processing station" model, forming a large-scale supply network of "ton-level raw materials-10,000 tons of pellets"

2. Improve production "efficiency and stability" to support industrial mass production

The core of renewable energy scale is "stable mass production", and early biomass processing equipment has the problem of "low hourly output and high failure rate". Modern biomass pellet machines (mainly ring die pellet machines) have achieved three major breakthroughs through technological iteration: production capacity leap, continuous operation capacity improvement, and reduced defective product rate

3. Promote product "standardization and commercialization" and open up large-scale application channels

For renewable energy to enter the mainstream energy market, it must meet the commercial standards of "stable quality and controllable indicators", and biomass pellet machines are the core tools to achieve this goal:

Stable calorific value: By controlling the raw material ratio (such as wood chips + 30% straw) and moisture content (15%-20%), the calorific value of pellet fuel can be stabilized at 4000-4500 kcal/kg (close to the calorific value of coal) 80%), and the fluctuation range is less than 5% (far exceeding the 30% fluctuation of scattered burning straw);

Pollutions are controllable: ash content is less than 5%, sulfur content is less than 0.05% (only 1/20 of coal burning), which meets the environmental protection standards of industrial boilers and biomass power generation (such as EU EN393/394 standards);

Morphology is unified: particle diameter (6-12mm) and length (2-5 times the diameter) are standardized, which can be directly adapted to the feed system of the existing coal-fired boiler transformation (no large-scale equipment transformation is required), lowering the application threshold.

Standardized pellet fuel has become a "plug-and-play" energy to replace coal and fuel oil

Fourth, activate the "synergy effect" of the industrial chain and form a large-scale ecology

The application of biomass pellet machine is not only a breakthrough in a single link, but also drives the synergy of the entire industrial chain from "raw material collection-processing-application-recycling" to form a large-scale ecology:

Biomass energy has moved from "supplementary energy" to "main renewable energy" - this is its core meaning as a "large-scale promoter".
