Increasing production is the top priority for straw pellet machine manufacturers. As is known to all, the disposal of crop straw after harvest is also a headache. In the past, it was all burned, causing great pollution to the environment. This is where the straw pellet machine came into being.
The emergence of straw pellet machines not only effectively alleviates the tight supply situation of biomass pellets, but also contributes to the healthy and stable development of the national economy. As long as the biomass is dried to a certain extent during the production of granules, the produced granules can be dried and stored for a long time. The impact of materials on the production of straw pellet machines is conducive to the production efficiency of high equipment and the forming rate of high equipment
Seven factors affecting the output of straw pellet machine:
1.Adding a small amount of oil (0.5% to 1%) to the oil is beneficial for reducing the wear of the components of the straw pellet machine and making the pellets pass through the die holes more easily, thereby increasing the output value of pelletizing. However, when the increase exceeds 2%, it will cause the particles to loosen and be difficult to form. Therefore, when increasing a high dose of oil, it is advisable to add 30% of the total amount at the mixer and 70% of the total amount at the straw pellet machine.
2. Appropriate crude fiber content (3% to 5%) is beneficial for the adhesion of the pellet material in the straw pellet machine, reduces the pulverization rate of the pellets, and increases the pelletizing output value. However, when the crude fiber content exceeds 10%, it will affect the hardness and forming rate of the pellets due to poor adhesion, increase mechanical wear, and reduce the pelletizing output value.
3. Moisture content of the material: If the moisture content of the material is too high, it will reduce the amount of steam added during pelletizing, affect the increase of pelletizing temperature, and then affect the output value and quality of the straw pellet machine's pellet feed. At the same time, if the moisture content of the material is too high, it will be difficult to temper and it is easy to cause the material to slip between the inner wall of the ring die and the pressure roller.
4. Protein materials have a high protein content. After being heated, the materials have great plasticity and increased viscosity, resulting in a high granulation output value. However, when non-protein nitrogen (such as urea, etc.) is high, the pelletizing output value of the straw pellet machine decreases.
5. Starchy grains have a high starch content and are easy to pelletize under high temperature and high moisture conditions, resulting in high output. At present, the moisture content of the straw pellet machine for conditioning should be between 16% and 18%. The quenching and tempering temperature should be above 80℃. Otherwise, the degree of starch gelatinization will be poor, resulting in brittle particles and even failure to form. If the grains have been matured before conditioning (such as dried corn), the granulation output will decrease. Therefore, when purchasing materials, it is better not to choose dried ones.
6. Heat-sensitive feeds such as lactose and whey powder increase in viscosity when heated, which can increase the output value. However, when the temperature exceeds 60℃, they are prone to coking, blocking the die holes and affecting the output value of the straw pellet machine. Therefore, when conditioning this type of feed, warm water can be used.
7. The mineral inorganic feed produced by the straw pellet machine has almost no adhesive force. Poor granulation function affects the output value of granulation. Therefore, when the inorganic content is high, a small amount of binder (such as molasses) is usually added to the material to improve the pelletizing function and increase the output value of the straw pellet machine.
