1. The working principle of wet hay/grass/alfalfa biomass pellet processing equipment

Wet straw pellet processing equipment is a special equipment designed for pelletizing grass raw materials (such as wheat straw, rice straw, etc.) with a high moisture content (usually 15%-40%). Its core features are designed around the three core needs of "adaptability to high-moisture raw materials", "efficient molding" and "reduced pretreatment costs". It can directly process wet straw with a moisture content of 15%-40%, greatly reducing the energy consumption and time cost of pretreatment. Pellet molding is achieved through mechanical extrusion heat generation. The core principle is "fiber softening + physical bonding". During the extrusion process, the friction between the straw and the pressure roller and ring die generates heat, which can soften the wax layer and hemicellulose in the grass (playing a natural bonding role) without the need to add exogenous adhesives such as starch and clay, ensuring the "pure natural properties" of the pellets (suitable for feed and biomass fuel scenarios).

2. Characteristics of wet hay/grass/alfalfa biomass pellet processing equipment

(1) Efficient production capacity: In order to meet the market demand for wet grass pellets, processing equipment usually has high production efficiency. For example, some large-scale wet grass pellet processing production lines can process several tons or even tens of tons of wet grass per hour. By optimizing the structure and operating parameters of the equipment, such as increasing the speed of pelletizing and increasing the efficiency of material transportation, efficient production capacity can be achieved, thereby reducing the production cost per unit product and improving the economic benefits of the enterprise.

(2) Stability and reliability: The stable operation of the equipment is the key to ensuring production continuity and product quality consistency. During the design and manufacturing process of wet grass pellet processing equipment, attention is paid to the quality and reliability of key components. For example, high-strength materials are used to manufacture vulnerable parts such as the pressure roller of the pellet mill to improve its wear resistance and service life. At the same time, it is equipped with advanced automatic control systems to monitor the operating status of the equipment in real time, such as temperature, pressure, current and other parameters. When an abnormal situation occurs, it can promptly alarm and take corresponding measures to ensure stable and reliable operation of the equipment and reduce downtime caused by equipment failure.

3. Application scenarios of wet hay/grass/alfalfa biomass pellet processing equipment

Wet grass pellet processing equipment plays a key role in modern agriculture, environmental protection, and energy. Its core value lies in converting high-moisture grass raw materials (such as fresh grass, straw, and reeds) into high-density, easy-to-store pellets through processes such as crushing, dehydration, and compression molding. This addresses seasonal fresh grass surpluses and shortages: excess fresh grass or silage during the rainy season can be processed into pellets to prevent spoilage; it can also be used as a high-quality feed supplement during the dry season or winter, ensuring balanced nutrition for livestock year-round.

Improving feed utilization: The pellet shape reduces picky eating, and the compression process breaks down plant cell walls, increasing starch and protein digestibility (experiments show a 10%-15% increase in digestibility for cattle and sheep).

TONY Brand 20-25  TPH Wet Hay/Grass/Alfalfa Line can process wet grass and various biomass materials related to agricultural waste into biomass pellets. Grass processing into biomass pellets has a wide range of uses .As fuel: grass pellet fuel can be used as boiler fuel for power plants, industrial boilers, civil heating and other fields. Its calorific value is similar to coal, but the price is lower, and the combustion process produces fewer pollutants, is a more environmentally friendly fuel. As feed: grass pellets processed by grass pellet machine can be used as feed for livestock. This method can make full use of grass, reduce feed costs, and also help solve the problem of grass disposal. These uses can not only effectively use agricultural waste, reduce environmental pollution, but also create economic benefits and promote sustainable agricultural development.

In 2025, as the global energy crisis deepens and the green transition accelerates, the wet grass biomass pellet market is experiencing explosive growth. According to the International Energy Agency (IEA), the global biomass pellet market has exceeded $50 billion, with an annual growth rate exceeding 15%. Carbon tax policies are driving a shift to cleaner fuels in the industrial sector (such as power plants and cement plants); the home heating market is experiencing robust growth in northern China (especially with the winter forecast to be colder in 2025); and export potential is enormous (European biomass pellet imports are increasing by 20% annually). Users may be interested in entering this niche market, and wet grass pellets offer a significant price advantage due to their low cost. Local policies, such as the Rural Revitalization Fund, are prioritizing such projects. Internationally, the Paris Agreement strengthens the carbon trading mechanism, allowing entrepreneurial projects to generate additional income through carbon credits.

1. Space Savings

After high-temperature compression, wet grass biomass pellets significantly save storage space.

2. High Combustion Thermal Efficiency

Wet grass biomass pellets significantly improve the combustion performance of wood materials, increasing thermal efficiency by over 80%. One ton of biomass pellet fuel generates the equivalent amount of heat as 0.8 tons of coal. Its calorific value is tested using specialized equipment.

3. Safety

Because wet grass biomass pellets are derived from natural biofertilizers or wood, they contain no fissile or explosive chemicals, preventing poisoning, explosions, or leaks.

4. Sustainable Use

The ash from burning biomass pellets can be used as fertilizer, promoting new plant growth and reinvigorating the biomass resource supply and sustainable utilization.
