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

(1) Feed: The pre-treated straw raw materials are conveyed to the feed inlet of the pellet nachine and uniformly sent into the pellet nachine chamber by the feeder.

(2) High-pressure extrusion: The pressure rollers in the granulation chamber will tightly press the materials onto the ring or flat molds with mold holes (usually with diameters of 6-12mm), and the materials are squeezed into the mold holes under the action of huge pressure (usually 30-100 MPa).

(3) Cutting and shaping: After the materials are extruded from the mold holes, they form continuous cylindrical strips, which are then cut into particles of the set length by the high-speed rotating cutter, and finally cooled and transported through the cooling conveying system to complete the finished product.

2. Characteristics of  wet straw biomass pellet processing equipment

(1) Strong pre-treatment capability: Specifically addressing the "wet straw" problem

The pre-treatment system of the equipment has been specially designed to efficiently process wet straw with high moisture content and high fiber content. This is the most fundamental difference from ordinary dry material granulation equipment.

(2) Stable molding design: Ensuring particle quality and production efficiency

Due to the characteristics of wet straw being prone to loosening and difficult to bond, the equipment has made multiple optimizations in the molding process to ensure stable particle quality and reduced brittleness.

(3) Environmental protection and energy conservation: Meeting green production requirements

The equipment is designed to minimize pollution and energy consumption, aligning with current environmental protection policies and sustainable development concepts.

(4) High adaptability and flexibility: Meeting diverse needs

The equipment can be adjusted according to the type of raw materials and production scale, and is suitable for different production scenarios of users.

3. Application scenarios of  wet straw biomass pellet processing equipment

(1) Farm processing: Large farms (such as pig farms and chicken farms) can use the equipment to process wet straw. The processed pellets can be used as heating fuel for themselves, mixed with feed (special treatment is required), or used to produce organic fertilizer around the farm (the ash after burning the pellets can be used as organic fertilizer raw materials), thus achieving the "straw-energy-fertilizer" cycle.

(2) Environmental protection project support: In agricultural non-point source pollution control and straw comprehensive utilization demonstration projects, the equipment is used as a core processing tool to process wet straw in the project coverage area and convert it into clean pellets. As the project's "resource utilization results", it helps the project achieve environmental protection assessment goals and obtain policy subsidies.

TONY Brand 80-100 TPH Wet Straw Line can process wet straw and various biomass materials related to agricultural waste into biomass pellets. Straw processing into biomass pellets has a wide range of uses .As fuel: straw 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: Straw pellets processed by straw pellet machining can be used as feed for livestock. This method can make full use of crop straw, reduce feed costs, and also help solve the problem of straw disposal. These uses can not only effectively use agricultural waste, reduce environmental pollution, but also create economic benefits and promote sustainable agricultural development.

Operation and marketing of the project of processing wet straw into biomass pellets

1. Production operation: control cost and quality

The core of the production process is to balance "pellet quality" and "operating cost" to avoid losses due to improper operation.

(1) Cost control: The energy consumption of the drying process accounts for 40%-50% of the total energy consumption. It can be equipped with a biomass burner (using crushed materials or unqualified pellets as fuel) to reduce drying costs; in terms of labor, a medium-sized production line can be equipped with 3-5 people (responsible for raw material acceptance, equipment inspection, and finished product packaging) to reduce labor expenses.

(2) Quality control: Strictly control the moisture content of the straw after drying to 10%-15% (too high moisture content will cause the pellets to break easily, too low moisture content will cause high energy consumption), maintain the molding pressure at 30-100MPa, ensure that the pellet density is ≥1.1g/cm³ and the length is 5-15mm, which meets the industrial fuel procurement standards.

2. Marketing: Clearly define the profit outlet

Sales are the key to project profitability. Target customers must be locked in advance to avoid backlog of finished products. 

(1) Core customer types: Local industrial enterprises: such as food factories, building materials factories, and livestock farms, which use biomass pellets as a boiler fuel to replace coal and can sign long-term supply agreements (usually settled on a quarterly or annual basis). Biomass power plants/heating companies: These customers purchase in large quantities but have high requirements for pellet quality. They need to submit samples for inspection in advance to be included in the supplier list. Farmers/small users: They sell to surrounding farmers for home heating or cooking. They can adopt a "bag retail" model to increase local market penetration.

(2) Pricing strategy: Based on local coal and natural gas prices, the price of pellets is usually 80%-90% of coal, ensuring price advantages while reserving a 15%-20% gross profit margin.

The core advantage of straw biomass pellet feed lies in its ability to transform low-value straw into a highly effective feed for ruminants (cattle and sheep) through nutritional optimization, improved physical form, and ease of use. This simultaneously addresses the three core requirements of reduced breeding costs, stable feed quality, and improved breeding efficiency.

1. Nutritional Advantage: Good palatability and balanced nutrition increase livestock and poultry feed intake and growth efficiency.

This is the core value that distinguishes pellet feed from traditional loose straw, directly addressing the issues of straw being "unpalatable and nutritionally poor."

2. Physical and Storage Advantage: Easy to store and transport, reducing losses and costs on the farm side.

The pellet form fundamentally addresses the challenges of traditional straw feed, namely, difficult storage and expensive transportation, significantly reducing back-end costs for farms.

3. Usage Advantage: Convenient operation and strong controllability reduce labor and management costs.

The simplified use of pellet feed significantly reduces farm labor and management complexity. 4. Economic and Resource Advantages: Low cost and resource recycling meet the aquaculture industry's need for cost reduction.

From raw material costs to resource utilization, pellet feed offers significant economic advantages, meeting the current aquaculture industry's core need for cost reduction and efficiency improvement.
