When pelletizing, the moisture content of raw materials should be lowered from 25-30% to 10-15%. Dry raw materials are difficult to form, while over-high moisture will make the pellets lose and cause them to jam in the pellet machine. This can result in higher production costs, lower output capacity, and poor-quality wood pellets.
Choosing the Right Raw Materials for Your Pellet Plant
When choosing a raw material for your
pellet mill, you should consider factors such as price, availability, and target market. This will help you select the best product for your pellet plant and produce a high-quality pellet that meets market requirements.
The raw materials you choose will also influence the fuel properties of your pellets, including their burning characteristics and emissions. For example, hardwood pellets tend to have longer burn times and high heat output than softwood pellets. They can also smolder more easily and release a lot of smoke during the burning process.
Moisture is a key factor in the performance of your pellet plant. Higher moisture levels in your starting material can lead to various production challenges, including jamming the pellet mill, high drying costs, and reduced output capacity.
Reducing the water content of wood pellet raw materials is important to achieve high-quality pellets with high energy efficiency. Here are some ways to reduce water content during the pelletizing process:
The raw materials should be dried before pelletizing. This can be done by spreading them out in the sun, using a dryer, or using a dehumidifier. The recommended moisture content for wood pellets is around 10%. Raw materials should be stored in a dry place to avoid moisture absorption. If they are exposed to moisture, the water content will increase, and it will be harder to dry them. If the raw materials are too large, they will have a high water content. Grinding them into smaller pieces will increase the surface area, allowing the moisture to evaporate more quickly. Pre-conditioning can help reduce the water content of the raw materials. It involves adding steam or water to the raw materials to soften them and make them more pliable. Pelletizing at high temperatures can also help reduce the water content of the raw materials. This is because the heat causes the moisture to evaporate.
You can also purchase a dryer machine for your production facility to lower the moisture content of your raw materials. This can be an efficient way to improve the molding rate of your pellet mill and produce higher-quality pellets.
Using a pellet machine to make your own wood pellets is an inexpensive and eco-friendly alternative to purchasing them from the store. The pellets are made from sawdust or other raw materials that have been seasoned and dried to a low moisture content. These wood pellets are then extruded into a cylindrical shape, usually with broken ends. They are then cooled and hardened before being stored in a silo for future use or distribution to a customer.
