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

Straw pellet machine is a machine that compresses various types of biomass waste, such as straw, rice husk, sawdust, wood chips, etc., into a shaped fuel with a certain shape and high density by mechanical pressure. After the raw materials are extruded and formed, the density can reach 0.8-1.3t/m³, the energy density is equivalent to that of medium-quality coal, and the combustion characteristics are significantly improved.

2. Characteristics of  wet straw biomass pellet processing equipment

(1) No need for natural drying, saving space and labor costs: The equipment can directly process wet straw with a moisture content of 30%-60%. The raw material collection radius is smaller, reducing transportation costs. 

(2) Strong production continuity: As long as there is wet straw raw material, continuous production can be achieved, which is especially suitable for rainy areas or enterprises that need continuous production throughout the year. 

(3) Wide range of raw material adaptability and higher utilization rate: In addition to common wet straw such as corn stalks and wheat straw, it can also process a variety of high-moisture agricultural waste such as wet sawdust, sugarcane bagasse, and peanut shells. It can be flexibly switched according to local raw material supply conditions, improving raw material utilization and reducing dependence on a single raw material. 

(4) Reduced costs and more environmentally friendly. The equipment can use the lignin contained in the straw itself to play a bonding role under high extrusion temperature without adding any additives. The produced pellets are more in line with green fuel standards.

3. Application scenarios of  wet straw biomass pellet processing equipment

(1) Boilers in small and medium-sized enterprises: Many small and medium-sized enterprises need to use boilers in their production processes. Traditional coal-fired boilers are gradually restricted due to environmental issues. Biomass pellet fuel, as a clean energy source, can replace coal for use in boilers in these enterprises. 

(2) Home heating and hot water systems: With the improvement of environmental awareness and government support for clean energy, biomass pellet fuel has also begun to enter the home market. It can be used in home heating and hot water systems, such as fireplaces, heating stoves, etc. 

(3) Agriculture and forestry: In the fields of agriculture and forestry, biomass pellet fuel can be used to dry grains, heat greenhouses, etc. In addition, biomass pellet fuel made from crop waste can also help farmers deal with agricultural waste such as straw, reducing environmental pollution. 

(4) Industrial production: Some industrial production processes require a large amount of heat energy, such as food processing, textiles and other industries. Biomass pellet fuel can be used as a source of heat energy for these industries, reducing dependence on traditional fossil fuels.

The project of processing wet straw into biomass pellets focuses on establishing a "raw material recovery - processing production - fuel sales" industrial chain by addressing the issue of difficult storage and high transportation costs of wet straw. By solving the problems of difficult storage and high transportation costs of wet straw, this project aims to achieve the dual goals of resource utilization and commercial profitability of agricultural waste.

This project direction has great prospects. It not only aligns with environmental protection policies but also can revitalize idle rural resources and clarify the core elements of the project, helping you to proceed with the implementation more securely.

Core advantages of the project: Why choose the processing of wet straw

The wet straw processing project is more competitive in terms of raw material acquisition and regional adaptability, which is its core appeal.

1. Easy raw material acquisition and low cost: Directly purchase wet straw that has just been harvested in the fields, without waiting for natural drying. Farmers do not need to bear the drying cost, and their willingness is higher. The purchase price of raw materials is usually 20%-30% lower than that of dry straw; at the same time, the factory can be set up nearby, reducing the distance of raw material transportation (the transportation cost of wet straw is high, and processing nearby can reduce transportation costs by more than 50%).

2. Strong policy adaptability: Directly solve the problem of pollution caused by straw burning, which belongs to the "straw utilization" project. It is easy to apply for equipment purchase subsidies, production subsidies or local special support funds, reducing the initial investment pressure.

3.Stable market demand: Processed pellet fuel can be sold to industrial boilers, biomass power plants, heating companies, etc. Especially in areas with strict environmental protection policies, there is a strong demand for clean fuel. The wet straw project can quickly respond to the local market and reduce the transportation cost of finished products.

Straw biomass pellet feed offers significant advantages in storage, nutrition, and usage.

1. Physical Properties: Easy to store and transport, minimizing waste.

It has a high density and is resistant to moisture absorption and mold, allowing for a storage period of 6-12 months. The pellets are uniform in shape, free of dust, and have a transport loss rate of less than 3%, making them suitable for bulk purchases by large-scale farms.

2. Nutritional Properties: Good palatability and a more balanced nutrition profile.

During processing, straw fibers are softened (to a particle size of 2-3mm) and tempered (by adding water, molasses, urea, or trace elements) to improve palatability. This increases cattle and sheep intake by 20%-30% compared to loose straw, reducing picky eating and waste.

Nutritional formulas can be customized to meet livestock needs. For example, soybean meal or bran can be added to increase protein content (from the original 3%-5% in straw to 8%-12%), or minerals can be added to meet the nutritional needs of different growth stages (such as calves and fattening cattle), addressing the nutritional monotony of loose straw. 

3. Usage Features: Convenient Operation and High Controllability

No pre-cutting or silage preparation is required; the pellets can be fed directly or with minimal soaking, reducing pre-processing steps on the farm. A single person can complete the feeding operation, reducing labor costs.

The pellet feed's consistent nutritional content per unit weight facilitates precise control of feeding amounts, avoiding growth variations in livestock and poultry caused by uneven nutrition in loose straw and improving breeding efficiency.
