How to make straw pellets by straw pellet machine?

Clicks:

In recent years, many countries and regions have vigorously promoted the comprehensive utilization of straw machinery and straw fertilizer, raw material, feed, base material, and energy in accordance with local conditions. This wave of actions once again drove the biomass pellet industry, including straw pellet machines.

Straw pellets are granular products made by crushing, compressing, and molding crop straw. Straw pellets have the characteristics of high density, easy storage and transportation, and high combustion efficiency, and are widely used in feed, fuel, and organic fertilizer. What kind of straw pellet machine do you know? Common straw pelletizers include rice straw pellet machine, paddy straw pellet machine, wheat straw pellet machine, corn straw pellet machine, concord straw pellets machine, cotton stalk pellet mill, etc.

Types of straw pellets

Depending on their uses, straw pellets are mainly divided into the following categories:

  • Straw feed pellets:
    used for livestock feed, rich in cellulose and crude protein, suitable for ruminants. Straw feed pellets are mainly used as feed for ruminants (such as cattle and sheep). After straw is processed, cellulose and hemicellulose are easier to be digested and absorbed by animals, which can improve the utilization rate of feed.
  • Straw fuel pellets:
    used to replace traditional fuels such as coal and natural gas, with high calorific value and low pollution. Straw fuel pellets are a clean energy source that can replace traditional fuels such as coal and natural gas. It has high combustion efficiency and emits fewer pollutants, which meets environmental protection requirements.
  • Straw organic fertilizer pellets:
    used for fertilizing farmland, can improve soil structure and increase soil organic matter content. Straw organic fertilizer pellets can improve soil structure, increase soil organic matter content, and promote crop growth. After fermentation, straw can provide nutrients required by plants and is an environmentally friendly fertilizer.

Raw materials of straw pellets

The raw materials of straw pellets mainly come from crop straw. Common raw materials include:

  • Corn straw: the straw after corn harvest, rich in cellulose and hemicellulose.
  • Wheat straw: the straw after wheat harvest, suitable for processing into feed and fuel pellets.
  • Rice straw: the straw after rice harvest, often used for fuel pellets and organic fertilizer pellets.
  • Soybean straw: the straw after soybean harvest, suitable for processing into feed pellets.
  • Cotton straw: the straw after cotton harvest, suitable for processing into fuel pellets.

In addition, the straw of other crops such as rapeseed, sugarcane, peanuts, etc. can also be used as raw materials.

What's straw pellet machine?

The straw pellet making machine uses crop straw or sawdust as the main raw material, and is pressed into cylindrical pellets by the straw pellet machine. Depending on the quality of the raw materials, the compressed pellets can be used as biomass fuel or as feed for livestock and poultry. The RICHI straw pellet machine absorbs the essence of the pellet machine and is a new energy-saving product.

In the past, the feed was generally processed into powder and then fed, but there were defects such as inconvenient feeding, poor palatability, picky eating by livestock, and low utilization rate. With the advent and popularization of new straw pellet machinery for feed, powder feed can be conveniently processed into pellet feed. It can use lighting electricity as power to press straw pellets from the die hole under the squeeze of the pressing roller, and the length of the straw pellets can be easily adjusted. The structure is simple, the floor space is small, and the noise is low.

What's Straw Pellet Machine

How to make straw pellets by straw pellet machine?

The working principle of the straw pellet machine is to compact and squeeze raw materials such as straw, wood chips, rice husk, etc. out of the mold under the high temperature and high pressure environment of the pelletizing cavity through the extrusion and friction generated during the movement of the ring die and the pressing roller. Holes, and finally form a regular, denser fuel. Ring die and pressure roller are the core components of the straw pellet machine equipment. The ring die and material feeding are arranged horizontally relative to the whole straw pellet machine. The powder material of the horizontal straw pellet machine is fed vertically from the front end of the granulating cavity (with the help of the fan. Forced feeding), the ring die and the straw pelletizing unit are arranged vertically.

At present, the straw pellet machine products of various manufacturers have differences in the core work component structure, the technical route of the whole machine, and the design of product efficiency, and the reliability of similar straw pellet machine products has a large gap. The service life of the straw pellet machine ring die and the pressing roller is relatively short, and the frequency of maintenance and replacement is high, which is the main reason for the high cost of the straw pellet machine. It is recommended that when purchasing the ring die and pressure roller of the ring die straw pellet machine, you must choose a manufacturer with excellent technology and a certain scale.

Differences in the process and equipment for processing straw feed pellets, straw fuel pellets and straw organic fertilizer pellets

Although the processing procedures of the three types of straw pellets are similar and the processing equipment has some overlap in function, there are some differences in the specific process and specific configuration:

Straw Feed pellets:

Focus on the nutritional content of the raw materials, and usually need to add other feed raw materials (such as soybean meal, corn flour, etc.) to improve the nutritional value. The hardness and density of the pellets are required to be high during the processing to facilitate animal digestion. In the process of processing straw feed pellets, a mixer is required to add other feed raw materials, and the pellet machine needs to have a high compression capacity to ensure the hardness and density of the pellets.

Fuel straw pellets:

Focus on the calorific value and combustion efficiency of the raw materials, and usually require a low moisture content of the straw (below 10%). The density and combustion performance of the pellets are required to be high during the processing. In the process of processing straw fuel pellets, a dryer is required to reduce the moisture content of the straw, and the pellet machine needs to have a high compression capacity to ensure the density and combustion performance of the pellets.

fertilizer straw pellets:

Focus on the organic matter content and fermentation effect of the raw materials, and usually need to be fermented. The processing process has high requirements for the organic matter content and nutrient release rate of the pellets. In the process of processing straw fertilizer, fermentation equipment is required for fermentation treatment, and the pellet machine needs to have a high compression capacity to ensure the organic matter content and nutrient release rate of the pellets.

Comparison of the cost of processing straw feed pellets, straw fuel pellets and straw organic fertilizer pellets

The processing costs of the three types of straw pellets are different, mainly reflected in the following aspects:

Raw material cost: Feed pellets usually need to add other feed raw materials, so the raw material cost is higher; the raw material cost of fuel pellets and organic fertilizer pellets is relatively low. Equipment cost: The equipment cost of feed pellets and fuel pellets is relatively low, while organic fertilizer pellets require additional fermentation equipment, so the equipment cost is higher. Energy consumption cost: A lot of drying treatment is required during the processing of fuel pellets, so the energy consumption cost is high; the energy consumption cost of feed pellets and organic fertilizer pellets is relatively low.

Overall, the processing cost of straw feed pellets and straw fuel pellets is relatively low, while the processing cost of straw fertilizer pellets is high.
