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

(1) Feeding: The crushed dry straw material is fed into the pelletizing chamber of the pelletizer at a uniform speed by the feeder to avoid feed jamming caused by over-drying of the material.

(2) High-pressure extrusion: The roller in the pelletizing chamber presses the material tightly against a ring die with a die hole (diameter 6-12mm). Under the action of high pressure, the material is squeezed into the die hole to form a continuous cylindrical strip. The friction of dry straw is relatively small, and some equipment will appropriately increase the pressure of the roller to ensure the molding density.

(3) Cutting and cooling: The cylindrical strip is cut into 5-15mm pellets by a high-speed cutter. Since the friction heat generated by dry straw during extrusion is relatively small, the pellet discharge temperature is usually 50-80℃. Some small equipment can omit the cooling step and directly air cooling can meet the standard; large-scale production lines need to be equipped with a cooler to ensure that the pellet temperature drops to room temperature to avoid agglomeration during storage.

2. Characteristics of dried straw biomass pellet processing equipment

(1) Simplified pretreatment process: No drying required, reducing equipment complexity

This is the core feature of dry straw equipment. It is directly adapted to low-moisture raw materials, eliminating the key link of wet straw equipment

(2) High molding stability: Adapting to the characteristics of dry materials, reducing failures

In view of the characteristics of dry straw being brittle and weak in adhesion, the equipment has made targeted optimizations in the molding process to ensure production continuity.

(3) Better energy consumption and cost: Strong long-term operating economy

From equipment operation to later maintenance, the cost advantage of dry straw equipment is more obvious, especially suitable for long-term large-scale production.

(4) Adaptability to large-scale production: High production capacity and automation compatibility

Dry straw equipment is easier to achieve high production capacity and automated control, suitable for large energy companies or centralized processing projects.

3. Application scenarios of dried straw biomass pellet processing equipment

(1) Agricultural drying fuel: Farmers and grain drying factories use the heat generated by the combustion of pellets to dry grains such as corn, rice, and wheat, replacing traditional coal drying or natural drying methods. The combustion temperature of the pellets is stable (up to 800-1000°C), with high drying efficiency and no grain odor, meeting food safety standards.

(2) Auxiliary for organic fertilizer production: During the fermentation process of organic fertilizers, dry straw pellets can be burned to provide stable heat for the fermentation pile (maintaining a fermentation temperature of 55-65°C), accelerating the decomposition of organic matter; at the same time, the ash after the combustion of the pellets is rich in potassium, calcium, etc., and can be directly added as raw materials for organic fertilizers, achieving a complete chain recycling of "straw - energy - fertilizer".

Cost Advantages of Dry Straw to Biomass Pellets

Cost control is key to project profitability. Dry straw projects offer significant advantages in both initial investment and long-term operations. Dry straw to biomass pellet projects require low equipment investment and low operating energy consumption, lowering the threshold for profitability.

1. Lower Equipment Investment:

There is no need for the costly drying systems (such as drum dryers and hot air furnaces) required for wet straw projects. Total equipment investment is 25%-35% lower than for wet straw projects, significantly reducing initial capital pressure.

2. Lower Operating Energy Consumption:

Dry straw has already reached the desired moisture content (10%-15%), resulting in 30%-50% lower energy consumption per ton of pellet processing than for wet straw projects, saving 20%-30% in annual electricity costs. 

3. Low raw material storage costs:

Dry straw is less susceptible to mold and can be stored for long periods (6-12 months) in ventilated, rainproof sheds. This eliminates the need for silage pits or temperature-controlled warehouses required for wet straw projects, reducing storage facility costs by over 60% and eliminating the need for additional costs such as mold inhibitors.

1. Eliminating pollution from straw burning:

Converting straw, which previously produces PM2.5 and sulfur dioxide, into solid pellets reduces pollutant emissions by over 90%, solving the straw disposal problem at the source and avoiding environmental penalties.

2. Renewable and zero land occupation:

Using agricultural waste as the raw material, there is no need to mine it like coal or oil, nor does it require arable land like grain crops. The straw resource can be recycled annually.

3. Zero waste throughout the entire supply chain:

Pellets produced during production can be recycled, and the ash from combustion/feeding can be used as organic fertilizer. This achieves a resource utilization rate of over 95%, creating a closed loop of "straw - pellets - ash - fertilizer" with no residual waste.

4. Significantly Reduced Storage and Transportation Costs:

With a density of 1.1-1.3g/cm³ (energy pellets) or 0.8-1.0g/cm³ (feed pellets), these pellets are 10-20 times denser than loose straw. One ton of pellets requires only 1-1.5m³ of space, reducing storage costs by 80%. Transportation losses are less than 3% (compared to 10%-15% for loose straw), resulting in a 40%-60% reduction in freight costs.

5. Improved Efficiency and Stability:

Energy pellets boast a combustion efficiency exceeding 85% (compared to 50% for loose straw), a stable calorific value of 15-18MJ/kg, and precise temperature control. Feed pellets also improve palatability (cattle and sheep feed intake increases by 20%-30%) and digestibility by 15%-20%, addressing the inefficiency and instability associated with loose straw.
