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

The overall principle of dry sawdust processing equipment can be summarized as follows: First, the dry sawdust is pre-treated to meet the requirements for pelletizing (removing impurities and adjusting moisture content). Then, high-pressure extrusion and frictional heating in the pelletizing machine soften and bind the lignin in the sawdust, forming high-density pellets. Finally, post-processing ensures that the pellets are stable, uniform, and meet quality standards for shipment. This entire process uses no chemical additives; it relies solely on physical processes and the natural lignin in the wood for pellet formation. This ensures the environmental friendliness of the final product and the stability of the processing, making it the core technology supporting the resource utilization of dry sawdust.

2. Characteristics of dried sawdust biomass pellet processing equipment

(1)Outstanding Processing Efficiency: Equipped with a high-pressure compression system, it can compress loose sawdust into pellets with a density of 1.1-1.3 t/m³, achieving a high pelletizing rate.  A temperature control system prevents pellet cracking by regulating the processing temperature, improving the finished product quality and reducing energy consumption, thus meeting the requirements for efficient production.

(2)Stable Structure and Operation:  The modular design allows for flexible configuration of different components to suit various production capacities (from several hundred kg to several tons per hour).  Wear-resistant alloy materials are used for critical components (such as rollers and molds) to extend their lifespan.  Some models feature a PLC control system for automated operation, minimizing manual intervention.  A robust sealing design reduces the probability of malfunctions, and the equipment is easy to start and stop, suitable for both intermittent and continuous production.

(3)Environmental Protection and Safety: Most machines are equipped with dust collection systems (such as pulse jet dust collectors) to reduce dust pollution during processing. Some models also feature noise reduction design, complying with environmental standards.  Overload protection and emergency stop buttons ensure safe operation by automatically shutting down the machine in case of malfunctions.

3. Application scenarios of dried sawdust biomass pellet processing equipment

(1)Agriculture and Planting: Preparation of Organic Substrates/Fertilizers,In agriculture, forestry, and edible mushroom cultivation, processed sawdust can serve as a functional substrate, enhancing cultivation efficiency:

Edible Mushroom Cultivation: Dry sawdust can be processed into uniform granules (or pulverized and refined) and mixed with bran, gypsum, etc., to create a growth medium for large-scale cultivation of shiitake, black fungus, and oyster mushrooms. The porous structure of sawdust provides good aeration, beneficial for mycelial growth.

Organic Fertilizer Carrier: Dry sawdust granules can be mixed with animal manure, straw, etc., and fermented to produce organic compound fertilizers. Sawdust regulates the carbon-nitrogen ratio of the fertilizer, improving water retention and nutrient-holding capacity, suitable for fruit and vegetable cultivation and seedling nurseries.

Soil Conditioner: Processed, fine sawdust granules can be directly mixed into sandy or heavy clay soils to improve soil structure, increase aeration, and enhance organic matter content, particularly suitable for soil improvement in greenhouses and orchards.

(2)Pet Supplies and Packaging: Production of Functional Additives,With the growth of the pet industry and the demand for environmentally friendly packaging, processed sawdust products are expanding into various consumer applications:

Pet Bedding: Dry sawdust can be processed into dust-free, absorbent granules for use as bedding for cats (mixed with bentonite or used alone), hamsters, rabbits, and other small pets.  It is highly absorbent, easy to clean, and biodegradable.

Eco-friendly Packaging Filler: Sawdust can be processed into lightweight granules or chips to replace traditional foam or bubble wrap for cushioning electronic products and ceramics during transportation.  It is biodegradable, reducing plastic waste.

In terms of raw materials and production, they boast a broad and low-cost source. Relying on waste sawdust from wood processing plants and furniture factories, they eliminate the need for additional farmland or the consumption of high-quality resources, resulting in a low raw material price. Furthermore, the production process is chemical-free, relying solely on the sawdust's own fibers bonded together under high temperature and high pressure, preserving the product's natural properties. Furthermore, their uniform shape makes them easy to store and stack, reducing warehouse space and transport costs by 30%-50%.

In terms of performance, their high combustion efficiency and low pollution levels are their key advantages: Their combustion efficiency exceeds 85%, far exceeding that of traditional coal, enabling rapid heat release. Their ash content after combustion is only 2%-5%, and their sulfur content is less than 0.05%, significantly lower than that of coal. Pollutants such as sulfur dioxide and dust are minimal, meeting national environmental standards and offering a direct alternative to fossil fuels such as coal and natural gas.In terms of application and value, it has a wide range of applications, meeting the heating needs of industrial boilers and power plants, as well as household heating and agricultural greenhouse heating. It is compatible with most existing combustion equipment, eliminating the need for major retrofits. It also offers stable economic returns and can benefit from renewable energy subsidies, tax exemptions, and other policies, combining environmental benefits with economic value.
