Wood drying equipment is specially designed and manufactured for the drying of sawdust, small wood chips and veneer. It is mainly composed of air heater, feeder, air drying pipe, cyclone separator and fan. We use the wood drying equipment to dry the wood, which is the process that the moisture in the wood is evaporated or evaporated from the wood. The specific methods and steps are as follows:
Let the wood adapt to the dry environment, set the heating rate of 2 ℃ per hour; During the heating process, due to the high initial moisture content of the wood, the moisture evaporated in the wood can ensure the simultaneous rise of dry and temperature; At the same time, turn on the electric auxiliary to maintain the heat shortage caused by humidification and heating.

1. Set the temperature of wood drying equipment at 60 ℃ and 70 ℃; After cooking, the water speed of the wood is relatively fast, and it is the early stage of wood free water discharge. The standard technology adjustment makes the wood temperature high inside and low outside. In this stage, more than 40% of the non pressure water can be quickly discharged, which takes 16 hours. The wood dried evenly and the cracking rate decreased. The traditional drying method of burning coal often causes the upper layer of wood to dry fast and the middle part to dry slowly because of too high temperature. The uneven drying will make the upper layer of wood blacken and affect the product quality. In addition, uniform temperature also greatly reduces the cracking rate of wood.

2. When the moisture content of wood falls below 20%, the drying speed will slow down. At this time, only the dry bulb temperature is increased to form a relatively dry relative humidity, forcing the moisture inside the wood to drain quickly. Labor costs are reduced. No workers are required to be on duty, and the operation is simple. After installation, they can start after simple training.
The original coal burning needs special personnel to see, there are labor costs to pay every day. When the moisture content of wood is below 15%, the moisture content in wood is very low, and the drying speed is slower than any previous stage. At this time, the dry bulb temperature is adjusted to 80 ℃.
The temperature can be adjusted. Different wood drying has different temperature requirements. It is difficult to control the temperature by traditional drying methods. But the air energy wood drying equipment can control the temperature and humidity, effectively reduce the damage to wood. When the moisture content of wood reaches 12%, it has reached or approached the requirement of moisture content. The moisture content in wood has not been eliminated, and the distribution of moisture content in wood is not very uniform, so the final balance treatment is needed.
The above is the wood drying equipment drying methods and steps, there are many methods of wood drying, because the density of wood is not the same, all need to choose the wood drying method according to their own needs.
