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) The wet grass pellet biomass pellet processing equipment has the characteristics of high efficiency and low energy consumption. It can quickly process biomass raw materials into fuel pellets and improve production efficiency.

(2) The biomass pellet machine has molds of various specifications. The corresponding molds can be selected for processing according to different biomass raw materials, improving the adaptability of processing.

(3) The biomass pellet processing equipment has a high degree of automation and good safety, effectively reducing labor intensity and improving production efficiency.

(4) The quality specifications of the pellet biomass fuel processed by the wet grass biomass pellet processing equipment are stable and meet the production standard requirements.

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

(1) Economic Benefits

The use of hay, weeds, and dead grass as biomass pellet fuel raw materials is due to their plentiful availability and low cost. Even after factoring in other costs such as fuel and power, wages and benefits, and equipment depreciation, the overall cost remains low. The price of hay pellets is currently rising, which can bring significant economic benefits to customers.

(2) Environmental Benefits

Improper handling of hay can pollute the environment to a certain extent. Pellets made from hay, burned in a dedicated gasification boiler, have a thermal efficiency of up to 81%. Carbon dioxide and sulfur dioxide emissions are near zero. It can replace non-renewable fuels such as coal and oil, while also reducing the environmental impact of waste.

(3) Social Benefits

The completion of the hay pellet production line will not only increase income, but also create jobs and reduce unemployment. Furthermore, this product can replace non-renewable energy sources, addressing the energy crisis and contributing to the establishment of a sustainable energy system and the promotion of economic development.

Biomass pellet fuel is energy-efficient and environmentally friendly, conserving non-renewable resources, and alleviating electricity and oil shortages. With the continuous promotion and application of biomass fuels, the demand for biomass pellet fuels will inevitably increase significantly in the future, and the market prospects are very broad.

Wet straw (corn stalks, rice straw, forage grass, etc.), as agricultural waste, has long faced the challenges of pollution from burning and high disposal costs. Processing it into biomass pellets can achieve triple value: Environmental value: It replaces coal combustion, reducing carbon emissions and aligning with the "dual carbon" strategy. Emissions per ton of pellets are reduced by more than 80% compared to coal, while also addressing the disposal challenges after the ban on straw burning. Energy value: The finished pellets have a density of 0.9-1.2 g/cm³ and a calorific value of 3500-4500 kcal/kg, making them suitable for direct use in industrial boilers, biomass power plants, and home heating, with a combustion rate exceeding 95%. Market potential: Domestic annual production exceeds 10 million tons, with strong demand in major agricultural production areas such as North and East China. Export prices to Japan and South Korea reach 1500 yuan/ton, and prices can increase by 10%-20% during the heating season.

Wet grass pellets, as a renewable energy source, can not only solve the problem of agricultural waste disposal, but also replace fossil fuels to reduce pollution. They are especially suitable for home heating, industrial power generation and agricultural applications, and are a win-win choice for environmental protection and economy. The carbon dioxide emissions during combustion are balanced with the absorption during the growth cycle of the raw materials, and it is a carbon-neutral fuel; the emissions of harmful gases (such as sulfur dioxide and nitrogen oxides) are much lower than those of coal, and the thermal efficiency is over 80%. The heat of 1 ton of pellets is equivalent to 0.8 tons of coal, and the burning time is 8-10 times longer than that of bulk materials. The volume is greatly reduced after compression, saving storage space; the solid form avoids the risk of leakage, and the transportation cost is lower. It does not contain flammable and explosive components, and there is no risk of poisoning or explosion; the ash after combustion can be recycled as fertilizer. The raw materials are agricultural waste (such as wet grass and straw), the cost is lower than gas and fuel oil, and the operating cost is 60% lower than electric heating.
