Product Description

A sawdust drum dryer machine is a type of industrial drying equipment designed to remove moisture from sawdust or other biomass materials. It consists of a rotating drum, heat source, airflow system, and moisture removal mechanisms. The drum dryer is commonly used in industries such as biomass energy, wood processing, and agriculture to dry sawdust for various applications.

Working Principle of Rotary Drum Sawdust Dryer

  1. Feeding: Sawdust or biomass materials are fed into the drum dryer through a feeding mechanism. The drum rotates slowly, allowing the material to spread evenly across the drum’s surface.
  2. Heat Source: A heat source, such as a gas burner, biomass burner, or electric heater, provides the necessary heat energy for drying. The heat source is positioned either inside the drum or externally, depending on the dryer design.
  3. Drying Process: As the drum rotates, the sawdust inside comes into contact with the hot air or gases generated by the heat source. The high temperature and airflow cause the moisture in the sawdust to evaporate.
  4. Airflow System: The drum dryer has an airflow system that circulates the hot air or gases through the drum. This helps to evenly distribute the heat and carry away the moisture released from the sawdust.
  5. Moisture Removal: To remove the moisture from the drying process, the drum dryer is equipped with moisture removal mechanisms. These can include exhaust systems, cyclones, or filters that separate the moist air or steam from the drying chamber.
  6. Discharge: Once the sawdust has reached the desired moisture content, it is discharged from the drum dryer. This can be done through a discharge mechanism, chute, or conveyor system.

Features of Sawdust Dryer Machine

  • The quality of the wooden block hot press is superior, the surface of the wooden pier tray feet is smooth and flat, good waterproof (no cracking after soaking in water for 48 hours, no cracking under the wind and sun), and strong nailforce.
  • Moulds can be customized according to the specifications and sizes of customers’ requirements. The products made are exempt from inspection and fumigation, and the formaldehyde release (E2) are in line with national standards.
  • The internal bonding strength is up to 1.07mpa. The vertical screw holding force is 1590N, and the flat behavior is 1660N, which is the ideal material for making non-fumigating wooden pallet support (foot pier, frame leg). It is mainly used to replace the foot pier used on the solid wood pallet, which is free from fumigation and heat treatment.

Raw Material for Sawdust Drum Drying Machine

The sawdust drum drying machine can not only dry all kinds of sawdust, wood chips, and crushed waste wood, but also all kinds of materials containing wood fibers. For example, sawdust drum dryers are used to dry barley straw, oat straw, wheat straw, rye straw, rice straw, sorghum straw, and corn stalk, as well as potato vines, legume stalks, etc. Our company can optimize the drying process technology of the sawdust dryer according to the characteristics of each wood material, the size of the output, the application requirements, the cost control, and the convenience of operation.

Sawdust is very common in life, and a large amount of sawdust is produced in various wood processing plants. This sawdust can be processed into various products such as sawdust compressed board and molded pallets. These sawdusts are usually dried when they are recycled. The sawdust rotary drum drying machine is specially designed for drying all kinds of sawdust.

The drum dryer is specially designed for the drying of sawdust, small wood chips and wood residue. Sawdust dryer adopts high temperature and rapid drying process, equipped with biomass fuel hot air stove, high degree of automation, and good quality of dried products. The drying system is equipped with safe fire protection devices, hot air waste heat utilization and other devices. The entire drum drying machine has large output, low cost, and safe and reliable production.

Advantages of Sawdust Drum Drying Machine

  • Efficient Drying: The rotating drum and airflow system ensure efficient heat transfer and moisture removal, resulting in faster drying times.
  • Uniform Drying: The drum’s rotation and material agitation help achieve uniform drying, ensuring consistent moisture reduction throughout the sawdust.
  • Energy Efficiency: The design of the drum dryer allows for the recovery and reuse of heat, improving energy efficiency and reducing operating costs.
  • Versatility: Drum dryers can handle a wide range of biomass materials, including sawdust, wood chips, shavings, and agricultural residues.
  • Automation: Advanced drum dryer systems can be equipped with automation features, such as temperature and moisture sensors, to optimize drying parameters and ensure accurate control.

Application of Sawdust drying Machine

1.Suitable for processing large amounts of wood chips. Because the wood chip drum dryer has a large production capacity, it is not suitable for household small output and is suitable for some wood processing plants.

2. It is suitable for granular and massive sawdust and can handle wet and poorly fluid sawdust. Usually, sawdust has a lot of impurities and high humidity, and the effect of using a drum dryer is good.

3. Some other materials similar to wood chips have good drying effects, such as chicken manure, bagasse, and some granular chemical raw materials.

4. Generally, the sawdust dryer can be used in the wooden pallet block production line and the molded wood pallet production line. When producing wooden pallet block and sawdust pallets, the raw materials contain moisture and the sawdust needs to be dried.
