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

The core principle of straw pellet processing equipment (such as wood chip pellet machines) is to convert biomass feedstock into high-density pellet fuel through mechanical compression. The basic process involves three steps: feedstock pretreatment (crushing and grinding), mechanical compression, and finished product processing (cooling and packaging). For example, in a ring die pellet machine, a motor connected to a reducer via a coupling drives the ring die. The feedstock enters the compression zone under the influence of gravity, where compression rollers squeeze the material into the ring die holes. After the pellets are formed in the die, they are cut into pellets of fixed length by a cutter.

2. Characteristics of dried straw biomass pellet processing equipment

Pelletizing is the core process, and the equipment design revolves around "utilizing the natural bonding of lignin to ensure pellet density": (1) Ring pelletizer: thick-walled ring die + large-diameter pressure roller. The ring die is made of double-layer wear-resistant alloy steel (wall thickness 15-20mm, ordinary ring die wall thickness 8-12mm), with high die hole finish (Ra≤1.6μm), which can withstand the severe friction of coarse fibers and has a service life of 300-500 hours (ordinary ring die is only 150-200 hours); the pressure roller diameter is increased to 180-220mm (ordinary pressure roller is 120-150mm), with a larger contact area and more uniform extrusion force, avoiding local overload and ring die cracking. (2) Adhesive-free design, relying on frictional heat generation

The equipment precisely controls the gap between the roller and the ring die (0.1-0.3mm) and the rotation speed (200-300r/min), generating a high temperature of 60-90°C in the die hole, which is just enough to soften the lignin (lignin softening point is 50-80°C). This eliminates the need for artificial adhesives such as starch and resin, reducing costs and avoiding the generation of harmful gases (such as formaldehyde) during combustion.

3. Application scenarios of dried straw biomass pellet processing equipment

1. Biomass Energy Production

This is the equipment's primary application scenario, with the finished pellets primarily used as a clean fuel.

Industrial Boiler Fuel: This fuel is used to power boilers in textile mills, chemical plants, food processing plants, and other industries, replacing traditional coal and reducing carbon emissions while complying with environmental protection policies.

Residential Heating/Cooking: In rural areas of northern China or in areas with centralized heating, pellets are used as fuel for wall-mounted boilers and biomass stoves, offering cleaner combustion and higher thermal efficiency than loose coal.

Power Generation: This fuel provides standardized fuel for biomass power plants, featuring high pellet density and stable combustion, ensuring continuous and efficient operation of the generator sets.

2. Livestock Feed: Dry straw pellets are processed into feed tailored to specific regions and livestock needs.

Ruminant Feed: Corn stalks, wheat straw, and other materials can be crushed and pelletized to form a base feed for ruminants such as cattle and sheep. The pellet form facilitates storage and feeding, and nutrients can be added as needed. Feed processing plant supporting equipment: Large feed mills use it as raw material processing equipment to convert straw into feed raw material pellets, which are then mixed with other ingredients to make complete feed.

TONY Brand 80-100 TPH Dried Straw Line can process dried 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.

The core of this project is to address the supply-demand imbalance between the difficulty of processing straw and the high demand for clean fuel. Compared to other entrepreneurial projects, it offers the following advantages:

1.Raw material advantages:

Dry straw is widely available at extremely low cost, primarily from corn, wheat, and rice-producing areas. The purchase price is low, and in some areas, it is even available free (farmers need to process the straw and are willing to sell it at a low price). The raw material supply is stable and unaffected by international market fluctuations.

2.Market advantages:

Downstream demand is robust and continues to grow. On the one hand, the "coal-to-biomass" policy in rural northern China is driving demand for residential heating. On the other hand, industrial boilers (such as those in food and textile factories) need to replace coal to meet emission standards, making biomass pellets a preferred choice.

1.Environmentally friendly and recyclable:

The raw material is dry agricultural waste straw, avoiding air pollution caused by straw burning. No chemical additives are used during combustion (it relies on its own lignin for bonding), resulting in far lower sulfur dioxide and dust emissions than coal. The ash contains potassium, calcium, and other elements, allowing it to be directly returned to the field as organic fertilizer, completing the "raw material - energy - fertilizer" ecological cycle.

2.Convenient storage and transportation:

The density of loose dry straw is only 50-80 kg/m³, but after being pelletized, the density increases to 1100-1300 kg/m³, significantly reducing the volume and saving storage space. The pellets have a regular shape, are dust-free, and are not prone to scattering. They can be transported by ordinary trucks, reducing transportation costs by over 70% compared to bulk straw. They are also compatible with automated feeding equipment (such as boilers and biomass furnaces).

3.Strong economic efficiency and wide application:

The raw material cost is extremely low, and the unit heat cost is lower than that of natural gas, liquefied gas and other energy sources. It is very attractive for scenarios such as civil heating, industrial boilers (food factories, textile factories), and biomass power generation. The market demand is rigid and stable.
