1. The working principle of  wet straw biomass pellet processing equipment

Wet straw biomass pellet processing equipment converts wet straw (such as corn straw and wheat straw) into high-density, regularly shaped biomass pellet fuel through a series of physical processes. This process relies on mechanical extrusion and the natural bonding of lignin, eliminating the need for additional adhesives. The wet straw biomass pellet processing process can be summarized as follows: raw material pretreatment (crushing, pulverization, drying) → extrusion molding → post-processing. Because the raw material is "wet straw" (usually with a moisture content of 10%-15%), deep drying is required. Instead, the process focuses on densifying the material through mechanical forces and utilizing the heat generated during processing to activate the binding properties of lignin, ultimately forming stable pellets.

2. Characteristics of  wet straw biomass pellet processing equipment

(1) Full-process integration capability: Crushing and pelletizing equipment forms a continuous production line, covering the crushing, grinding, drying, pelletizing, cooling and other links of raw materials. It is suitable for the production of biomass pellets from a variety of biomass raw materials such as bamboo, straw, sawdust, and sugarcane bagasse. The finished products can be used in power generation, artificial boards, papermaking and other fields.                                                                                                          (2) Environmental protection and economy: By processing waste such as straw and rice straw, resource waste is reduced. Pellet fuel has high combustion efficiency and low smoke, which is in line with the trend of energy conservation and environmental protection. The equipment is easy to operate and has low maintenance costs, making it suitable for large-scale production or individual operations.                                                                                                                                                                                                       (3) Application scenarios and industry adaptability: The processed straw pellets can be used as biomass fuel for home heating, industrial boilers or biomass power plants; the crushed straw can also be directly used to produce feed, realizing the diversified utilization of raw materials.

3. Application scenarios of  wet straw biomass pellet processing equipment

The application of straw pellet processing equipment is primarily concentrated in the energy, agriculture, environmental protection, and industrial sectors. The following are its core application scenarios and advantages:

1. Biomass Energy Production

Power Generation and Heating: Straw pellets, as a clean fuel, can replace coal in power plants or district heating systems, reducing carbon emissions.

Home Energy: Small pellet stoves are suitable for rural households, meeting daily cooking and heating needs.

2. Resource Utilization of Agricultural Waste

Reducing Incineration Pollution: Converting straw into high-density pellets avoids air pollution caused by open-air burning.

Improving Soil Fertility: Processing residues can be returned to the fields as organic fertilizer, improving soil structure.

3. Livestock Feed Additive

Nutritional Supplement: Compressed straw pellets increase digestibility and can be added to cattle and sheep feed to supplement fiber and energy.

Cost Optimization: Reduce dependence on traditional feed (such as corn straw) and reduce livestock costs.

4. Industrial Fuel

Industrial Boiler Fuel: Pellets have high combustion efficiency and are suitable for industrial boilers in industries such as ceramics and textiles. 5. Environmental Protection and Circular Economy

Carbon Neutral Contribution: The CO₂ released by burning straw pellets is roughly balanced by the CO₂ absorbed by plant growth, meeting low-carbon goals.

Extension of the Industrial Chain: Promoting an integrated "straw collection, processing, and sales" model will create employment opportunities in rural areas.

1.Environmental characteristics 

(1) Low pollution emissions: The sulfur and phosphorus content during combustion is extremely low, and the SO₂ and NOx concentrations in the flue gas are much lower than those of coal. It will not produce acid rain, and the CO₂ emissions are zero (because plants absorb CO₂ during their growth).

(2) Ash utilization: The ash after combustion is rich in organic potassium and can be recycled as a high-efficiency organic fertilizer. 

2. Economic benefits 

(1) Wide range of raw material sources: Straw is a kind of agricultural and forestry waste, which can produce millions of tons each year. The production cost of pellets is lower than that of traditional fossil fuels.            (2) Substitution benefits: Replacing coal can save about 20% to 30% of fuel costs. 

3. Wide range of application scenarios

(1) Industrial application: Widely used in boiler heating, power generation and industrial production, such as textile mills, food factories, etc.

(2) Civil heating and living energy: Straw pellets have high combustion efficiency, are easy to store and use, and are safe and hygienic.
