  Sawdust is an organic matter with a water content of about 40-50%. After drying, the water content is generally about 12%. The main water content is free water and biological water. Free water is easier to remove, while biological water is difficult to remove. The main methods for drying sawdust are natural air drying and mechanical drying.

  1. Natural air drying method

  Natural air drying is one of the traditional methods for drying sawdust. It has a simple process, does not require additional equipment and energy, and is low-cost. However, its drying speed is slow, is greatly affected by factors such as climate, season, and location, is not stable and is easily contaminated, and the quality of the sawdust after drying cannot be guaranteed.

  2. Mechanical drying method

  The mechanical drying method is to dry the sawdust through a professional sawdust dryer. It has a fast drying speed and high stability. The quality of the sawdust after drying can also be well guaranteed. Commonly used equipment includes rotary drum dryers, airflow dryers, etc. Among them, drum dryers are the most widely used in sawdust drying. Jiutian sawdust dryer adopts a new combined lifting device and a multi-layer sleeve structure to prevent the material from having wind tunnel phenomenon, so that the sawdust can fully exchange heat and dehydrate; and a coarse and fine particle separation device is added to greatly improve the heat utilization rate and also increase the output.

  In short, according to different needs and actual conditions, you can choose natural air drying or mechanical drying. For large-scale sawdust production companies, mechanical drying is more suitable.
