What are the drying requirements of Wood Chip Dryer?

Nowadays, wood drying requires both high quality and high efficiency,Wood Chip Dryer so everyone chooses wood drying equipment. Let's take a look at the drying requirements of wood drying equipment. Wood drying equipment drying stage:Wood Chip Dryer according to the process For the benchmark request operation,Wood Chip Dryer the temperature should be avoided during the insulation phase,Wood Chip Dryer and the temperature should be avoided during the benchmark phase adjustment; the preheating temperature must be determined according to different tree species and thicknesses. The initial preheating temperature does not exceed 45 ℃,Wood Chip Dryer and most of them are below 40 ℃. When it is hot,Wood Chip Dryer the wood must be allowed to penetrate into the dry stage, and steam can be sprayed if necessary;

Intermediate disposal: spray steam into the kiln to adjust the humidity of the air in the kiln. In the dry process,Wood Chip Dryer the speed of wood moisture change should be observed and recorded. The operator should enter the kiln to see if the wood surface cracks and deforms. If it occurs,Wood Chip Dryer it must be stopped and marked. According to the wood moisture drop and the wood surface Change the situation and inject steam into the kiln in time. The steam injection should be guaranteed for a long time,Wood Chip Dryer but it should not be too long. The intermediate disposal temperature is different from the request in this reference stage.Wood Chip Dryer The relative humidity is 5-8% higher than the equilibrium moisture content in this stage. The number of intermediate disposals can be stopped in time according to demand;

Balanced disposal of wood drying equipment:Wood Chip Dryer eliminate the difference in moisture content between different material piles in the kiln to ensure that all wood moisture content reaches the request when exiting the kiln. In the later period,Wood Chip Dryer it can be found that most probes have high moisture content, and a few have reached the request. In order to allow the wood in the kiln to pass the kiln,Wood Chip Dryer the balanced treatment must be stopped. The equilibrium treatment temperature is different from the final benchmark request; high humidity treatment:Wood Chip Dryer it is to eliminate the wood The thickness is uneven inside and outside.Wood Chip Dryer The high-humidity treatment temperature is equal to the final stage temperature of the reference,Wood Chip Dryer and the relative humidity is 4% higher than the final moisture content. The relative humidity of the equilibrium moisture content;Wood Chip Dryer Cooling out of the kiln: the temperature in the late drying period is higher. In order to avoid hot wood from bursting when exiting the kiln,Wood Chip Dryer The wood must be cooled before drying out of the kiln.
