Straw Pellet Production Line
Application: SBiofuel & feed production
Capacity:0.6-90T/H
The install period:7-90 Days
Raw materials:Crop waste
Straw pellet production line is a complete system that crushes, compresses and forms pellets of various crop straws, usually including cleaning, crushing, granulation, cooling, screening, packaging and other sections. Its basic principle is: through mechanical coercion, the raw materials are subjected to mechanical effects such as extrusion and friction, so that their own moisture content gradually decreases, becoming stable pellets without water or with extremely low moisture content. This production line is mainly used in the fields of feed, biomass fuel, etc., which can effectively utilize resources and reduce environmental pollution. In the future, straw pellet production line will have a wider application prospect and play an important role in the field of environmental protection and energy conservation.
Application of straw pellet production line
Straw pellet line can directly process crop waste such as corn straw, rice straw, cotton straw, soybean straw, flax straw, etc., into pellets, which are mainly used in the fields of feed, biomass fuel, etc. When processing these different types of straw pellets, the process of straw pellet production line is different.
- Feed:
After the straw pellet production line makes coarse raw materials such as straw into pellets, it can improve the nutritional content and taste of feed, improve the production performance of livestock, and reduce the cost of feed production.
- Biomass fuel:
The straw pellet processing line processes waste crops such as straw into pellets, which can be used to produce biomass pellet fuel, effectively utilize crop waste resources and reduce environmental pollution.
- Other applications:
In addition to feed and biomass pellet fuel, straw pellet machines have other application areas, such as organic fertilizer, pharmaceutical intermediates and other fields.
Straw pellets are widely used in daily life. Usually, straw pellets can be used as animal bedding, animal feed, and heating fuel for household and industrial use.
Process design of straw pellet production line
According to the different uses of straw pellets, straw pellet production lines are mainly divided into straw fuel pellet production lines and straw feed pellet production lines. The following is a detailed introduction to two different types of straw pellet processing technology:
01
Processing technology of straw fuel pellet production line
Straw solidification molding technology uses agricultural waste such as rice straw, wheat straw, corn straw as raw materials, and uses special equipment straw pellet machine to crush, compress and other processes to press into a solid biomass fuel that can be directly burned.
- Cut or crush the straw to be pressed into a rotary cutter and crusher, and control its length to less than 30mm.
- Send the crushed straw to the drum dryer through a conveyor. The moisture content is controlled within the range of 10-15%.
- After drying, the raw materials are piled and stored after unloading the silo, or stored in a silo.
- The material is sent to the feed port of the straw biomass pellet mill machine through the feeding conveyor. The machine rotates through the main shaft, driving the roller to rotate, and after the roller rotates, the material is forced to be squeezed out of the die hole in blocks and falls from the discharge port.
- Then the pellets are sent to the pellet cooler by a special conveyor.
- After the pellets are cooled, they are sent to the packaging scale or ton bagging machine for bagging.
02
Processing technology of straw feed pellet production line
Due to the similar composition of straw to wood, straw can be used to make grass pulp or converted into straw pellets. According to the particularity of straw, the granulation process of straw can be summarized as follows:
- Raw material preparation stage:
Straw usually has a high possibility of dust, which is affected by the harvesting method. Therefore, straw needs to be screened from contaminants such as dust and other foreign matter that may affect the quality of straw pellets, such as stones, metals, and those that may damage the pelletizer during the following procedures.
- Crushing stage:
Straw biomass is a tubular material with a diameter of 4-8mm and a wall thickness of about 0.3-0.6mm. With a tubular/tubular structure, straw can be easily processed and obtain the desired particle size. Usually, straw grinding includes cutting and crushing of straw.
- Drying stage:
Usually, straw is delivered in the form of air-dried bags with a moisture content of about 15%, which is suitable for the production of straw pellets. Therefore, the drying process of straw pellets is omitted. But if the moisture content of straw is large, the drying step is necessary.
- Conditioning:
Straw requires special conditioning to achieve the desired hardness. Straw conditioning includes the application of steam (and/or water) and the addition of binders or additives. Conditioning is required to achieve the necessary temperature and humidity to obtain ductility and melt lignin to act as a binder. Binders are required to enhance the hardness of the pellets and reduce wear during the pelletizing process.
- Granulation:
In the granulation process, it is necessary to consider the influence of factors such as material moisture, density, pellet size, fiber strength, natural adhesive, etc. on the granulation quality. Common problems in the process of straw pelletizing are clogging and breakage of pellet molds, overheating, high energy costs or poor pellet quality, and high maintenance rate of pelletizers. In order to avoid the above problems, a high-quality pelletizer is required.
- Cooling and screening:
The newly extruded straw pellets are hot and soft and need to be cooled to obtain the ideal hardness. At the same time, the screen on the cooler is used to screen out the pellets that do not meet the molding effect.
- Finished product packaging:
The cooled pellets need to be sent to the finished pellet bin by a professional skirt belt conveyor, and then unloaded from the finished pellet bin and packaged with a packaging scale.

FAQ
1.How to build a complete straw pellet production line?
- Are there any preferential policies for the external environment; subsidies for electricity taxes? Inquire with the local environmental protection department about the intensity of coal ban; attitude towards biomass straw pellet fuel; whether there are corresponding official documents?
- Investigate the quality, price and quantity of raw materials, and also consider the factors of long-term supply (i.e. long-term control). According to the raw materials, we can plan the configuration of the production line and analyze the cost.
- After determining the raw materials, we must determine the straw pellet plant. The factory building is generally close to the raw materials or convenient for transportation. It is best to have both.
- Transformer. The biomass pelletizing industry consumes a lot of electricity. After determining the production capacity, choose to purchase a transformer that matches the production capacity according to the equipment power provided by the equipment manufacturer.
- When purchasing equipment, you must first understand the product quality of the equipment manufacturer. It is often difficult to distinguish the quality of the product in the network environment.
You must go to the manufacturer for on-site inspection and don't be fooled by the low price. The straw pelletizer is a JASTEC invention patent and has now been upgraded to the 4th generation. RICHI Machinery's strong technical strength will escort you to make pellets.
