Working Principle of Rotary Drum Sawdust Dryer

When the drum drying machine is working, the drum is in a rotating state. The wood chips and the hot air heated by the heat source enter from one end of the drum and exhaust from the other end of the drum. When the drum rotates, the lifter in the drum lifts the wood chips, and the wood chips can be fully mixed with the hot air. The hot airflow passes through the wood chips and takes away the moisture in the wood chips. There is a partition layer in the drum, which can disperse the material and fully contact the hot airflow. At the same time, the partition layer can increase the residence time of the material in the drum.

The capacity of the material entering the drum is about 5-20% of the drum capacity. After the wood chips are dried in the drum, they enter the cooler for cooling, and finally, the wood chips are discharged from the outlet of the cooler. The waste heat and some sundries in the materials are sucked out by the exhaust fan.

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
wood chip

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

  • The drum drying machine produced by our company has a sealed structure, which can reduce heat loss and improve thermal efficiency.
  • The drum dryer has a good drying effect. Because the wood chips are highly dispersed in the airflow, the entire surface area of the particles can be in contact with the hot air.
  • The drum dryer has a simple structure, a small footprint, and is easy to install and maintain.
  • Large processing capacity and high thermal efficiency. The thermal efficiency can reach 60%.

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.
