Wood chip dryer plays an important role in wood processing and biomass energy industry, and the correct purchase of wood chip dryer is vital to improve production efficiency and product quality. The following will introduce the key points to pay attention to when buying and selling wood chip dryer.

First, the choice of dryer type

1. air dry dryer or rotary dryer: air dry dryer is suitable for wood chips with high humidity, while rotary dryer is suitable for wood chips with relatively low humidity. 

2. Horizontal dryer or vertical dryer: Horizontal dryer covers a large area, but is suitable for mass production, while vertical dryer covers a small area and is suitable for small production.

Second, the choice of heat source of the dryer

1. electric heating or gas heating: electric heating dryer is simple to operate, but with higher energy consumption; gas heating dryer has lower energy consumption, but complicated installation and operation.

2. combustion drying or indirect drying: combustion dryer provides heat source by burning wood chips itself, while indirect dryer indirectly heats wood chips through heat exchanger. Choose the heat source method that suits your production.

Third, the energy efficiency assessment of the dryer

1. Drying efficiency: The drying efficiency of the dryer directly affects the production efficiency and energy consumption. Selecting dryers with high drying efficiency can improve production efficiency and save energy. 

2. Energy consumption assessment: understand the energy consumption index of the dryer, including energy consumption, thermal efficiency, etc. Select low energy consumption and high efficiency. Choosing a low energy consumption and high efficiency dryer can help reduce production costs.
