straw pellet plant solution
Different uses require different straw pellet processing techniques. The following are several main straw pellet processing technologies currently used.
straw pellet plant for biofuel
The preparation method of straw pellet fuel is:
Use straw as raw material, after natural drying (moisture content ≤ 16%), use a pulverizer to crush it into powder (particle size ≤ 8 mm), then use a straw pellet machine to extrudate and then cool, screen, and pack or later recycling. The processing flow is: collection – drying – crushing – batching – dust removal – hot compression – forming – cooling – screening-bagging.
The conversion of straw into feed is an area of concern for many customers. Feeding straw directly will cause waste. If it is processed into straw pellet feed, it is easy to store and transport, which can improve economic benefits and facilitate commercialization.
straw pellet plant for feed
The straw pellet feed production line technology is a technology that kneads and crushes the straw into powder, and then uses pelleting equipment to press the straw into granular feed. The entire process includes coarse crushing, fine crushing, mixing, granulation, packaging and auxiliary systems.
Because straw fuel has high volatile content, less ash, less moisture, and is flammable, its combustion efficiency is as high as 95%. Under the same conditions, the thermal efficiency is increased by more than 7% compared with coal-fired, and the energy saving is about 10%.
straw pellet plant for organic fertilizer
It is mainly completed through composting fermentation or anaerobic fermentation, etc. Sometimes it requires precise formula design and mixing technology, which may involve granulation, coating and other processes.

how to make straw pellets? standard straw pellet production process
Except for the special processing method of straw organic fertilizer, the processing methods of straw fuel pellets and straw feed pellets can be summarized as the standard straw pellet processing technology: raw material preparation – raw material cleaning – raw material crushing – raw material drying – raw material mixing – straw pelleting – straw pellet cooling – straw pellet screening – straw pellet packaging.
These individual systems can be designed modularly. According to the needs, some processes are unnecessary, and the order between processes can also be adjusted according to the needs.
Raw material preparation
Your straw can be in any physical state (baled, long, crushed, with impurities, wet, dry, fermented, silage). Your raw material can be just straw, or you can add any other materials (agricultural and forestry waste, additives, etc.)
straw cleaning system (Optional)
In most cases, the raw materials of customers contain impurities, which requires the use of drum screens, iron removers and other equipment to screen out different types of impurities. The purpose of cleaning the raw materials is to ensure the quality of the pellets and to protect the equipment in the subsequent process.
straw crushing system (Optional)
Some straw is baled, some is very long, and some is crushed, which requires different crushers to process different straw raw materials. Bale breaker, shredder, straw crusher and other equipment are the most common.
straw mixing system (Optional)
In the process of straw pellet processing, some customers need to use a variety of raw materials. In order to ensure the uniformity of the pellets, these raw materials need to be mixed after crushing. Of course, the mixing section is also suitable for adding some additives to the raw materials.
straw drying system (Optional)
If the moisture content of the straw raw material is higher than 20%, a drying system is required. If there is a site or other conditions, customers can also use natural drying. If the moisture content of the straw is lower than 20%, there is no need to configure a drying system. Our drying system is not only for straw pellet processing, we can provide corresponding drying system equipment and equipment configuration for different raw materials.
straw pelleting system
We recommend different straw pellet machines for different types of straw pellet processing. Generally speaking, straw pellet machines can be divided into two categories: straw fuel pellet machines and straw feed pellet machines. Straw fuel pellet machines do not need to be equipped with a conditioner, while straw pellet machines used for processing feed do need to be equipped with a conditioner because the processing of feed pellets requires high temperature, maturation, and sterilization.
cooling & screening (Optional)
The temperature of the straw after pelleting is very high, and it needs to be cooled to room temperature to reduce the moisture content of the straw pellets for subsequent packaging and storage. In addition, during the processing of straw pellets, very few unqualified pellets and powder will be produced, so screening equipment is needed to screen out qualified straw pellets, and unqualified pellets and powder will be re-pelletized.
straw pellet bagging system (Optional)
The baling process is optional. Some customers process straw pellets for their own factories or farms, while others want to pack straw pellets into different specifications for easy sale. We can customize a complete pellet baling system, including filling, sewing, and stacking. We can also configure the baling system with conveying, dust removal, and other functions according to customer needs.

About Land planning and site selection for straw pellet plant
- Save land. Whether it is a new straw pellet plant or the renovation of an old straw pellet production line, land resources are a major investment.
- While trying to adopt new processes, new technologies, and new equipment, consider adding automated control systems, which will provide more resource preparation for the production, management, and later Internet marketing of the straw pellet production line.
- Environmental protection issues must be fully considered, and dust, odor, noise, earthquake resistance, logistics, lightning protection, fire protection, etc. in the straw pellet production line workshop must comply with relevant regulations and specifications. Therefore, when choosing a site, consider living areas away from people.
- Process design and equipment selection should cooperate with each other. Process design is an overall design closely related to civil engineering, power, water supply and drainage, etc. Different types of straw pellet production lines have different process designs. It is the selection of equipment. The principles of process design and equipment selection are: reducing the waste of personnel walking back and forth, reducing the waste of moving materials back and forth, reducing the waste of waiting, and reducing the waste of unqualified products. Make solid preparations for later lean production management.
- Straw pellet production line construction projects are usually proposed based on the long-term development plan of the industry or enterprise. Before making preparations for the straw pellet production line, the customer team must fully discuss but not limited to: the site selection, product line composition, production process, raw material description, equipment description, etc. of the new straw pellet plant.
- Policy orientation should also be one of the factors that customers consider, especially for complete compound straw pellet production lines. As the breeding area moves inward, forward-looking site selection needs to be considered in advance.
- After site selection, unified consideration should be given to whether a single-story factory building can be built, building density, green space ratio, building height, motor vehicle parking space configuration, non-motor vehicle parking space configuration, etc.
- Full consideration and discussion in advance will have a certain guiding role in the later graphic layout design and process design, and will avoid many detours.
How to process straw pellets? Detailed process description.
- If feed pellets containing only straw are processed, only one raw material is needed and no ingredients are required.
- During the processing of straw pellets, concentrates and other nutrients are often added to form a full-price feed, which not only improves the pelleting performance, but also complements nutrients and gives full play to the nutritional value of the feed.
- Usually, hot water is sprayed or steam is introduced to moisten the grass powder during granulation. The amount of water is generally controlled at 3-6% of the feed amount, so that the grass powder reaches a suitable moisture content for granulation of 14-16%.
- The grass powder should be crushed finer, or about 5% of oil or molasses can be added to the grass powder raw materials. The particle diameter is generally between 10-30mm.
- It can be determined according to the objects to be raised. The smaller the livestock and poultry, the smaller the required particles will be.
- The pellet density is preferably 1.2-1.3 g/cm³, and the pellet bulk density is between 550-600 kg/m³.
Straw pellets have the advantages of good palatability, large feed intake for livestock, short feeding time, and less waste. However, different equipment costs and final project operating expenses will also be different.
How to design a straw pellet plant?
The process design of the straw pellet production line is a relatively complex task. A good process design not only guarantees product quality, but also reduces investment and use costs. At the same time, the process design of the straw pellet production line also needs to be quite flexible and adaptable to meet the needs of producing various products.
- Use the product line description and raw material description in the early preparation stage to select process specifications and determine the process.
- Use the description of the straw pellet production process to calculate process parameters and select process equipment.
- Determine a good straw pellet production process, determine the power required for the process, and determine the dust removal, odor removal and noise reduction plan.
- Establish process operation procedures and determine program control methods with reference to ergonomics.
- Design and determination of information network.
Why use straw as raw material for biomass pellets?
Straw biomass pellets mainly use corn stalks, cotton stalks, wheat straws, tobacco stalks, etc.) as raw materials, and are extruded into rod-shaped biomass pellet fuels through the pressure of a biomass pellet press.
- It’s renewable energy
Straw is a green plant and a renewable energy source. Biomass fuel can reduce zero emission of CO, which is very beneficial to control climate warming. - It’s a low-pollution fuel
The pellet fuel made of straw as the main component is low-pollution. The oxygen content of straw fuel is 3-4 times larger than that of coal, with less heavy hydrocarbons, good combustion effect, and the blackness of smoke is lower than Ringelman level 1. - The economy is reasonable and the scope of application is wide
The cost of processing straw into pellet fuel is significantly lower than that of diesel and natural gas. The economic advantages of biomass pellet combustion boilers are very prominent.
Substituting fuel oil, gas, and electric heating boilers can save users a lot of operating costs. Compared with coal, although the price is similar, its superior environmental protection performance and renewability are unmatched by coal-fired boilers. - High combustion efficiency, saving energy
Due to the high volatile content of straw fuel, less ash, less moisture, flammability, mechanical, chemical, and smoke exhaust incomplete combustion heat loss is small, and the combustion efficiency is as high as 95%.
Under the same conditions, the thermal efficiency is increased by more than 7% compared with the coal-fired furnace, and the energy saving is about 10%.
