Veneer Drying Speed-manufacture,factory,supplier from China

As the main equipment for drying wood, the veneer dryer's drying speed will directly affect the quality and efficiency of drying veneers. Therefore, we must fully understand the factors that affect the drying speed in order to make it better. play a role.One of the main factors that affects the drying speed of the veneer dryer is temperature. The increase in temperature can accelerate the evaporation of moisture on the surface of the wood, so the drying of the wood will also be accelerated.

Our veneer dryer purchased by Myanmar customers last year is being delivered,and customers will receive it soon.We have a professional R&D team that can design different models according to customer’s special requirement.Perfect after-sale service system can supply 24h online service,remote operation is available on request,regular customer visits,sufficient spare parts supply in time.If you have any needs,please feel free to contact us.

1. Operating system:The planed (rotary) veneer is fed from the feed port of the wind-jet roller type veneer dryer, and through the relative rotation of several pairs of upper and lower rollers inside the dryer, the planed and rotary-cut veneer is rotated in the predetermined direction. Front running, during the veneer traveling process, the hot air of 110-150 degrees Celsius is vertically sprayed to the upper and lower surfaces of the veneer at the wind speed of V=1.5M/S through the air nozzle installed between the two pairs of rollers.

The 40m 2 deck veneer dryer purchased by an Indonesian customer has now been installed and is being debugged.Due to the epidemic,we could not send someone to guide the installation.The customer successfully installed it in our video and chat communication instructions.Thank you very much for your support Our biomass burner,which can directly burn all kinds of waste wood,saves fuel efficiently; it adopts automatic control and frequency conversion control system,which can automatically adjust the transmission speed and To achieve the ideal drying effect,if you are interested in our machine,pleas

1. Hot air temperatureAs the hot air temperature increases, the moisture content gradient, pressure gradient, water vapor diffusion coefficient and moisture conductivity coefficient all increase, and the evaporation rate of moisture in the veneer increases.In the constant speed drying stage, the drying rate is almost linearly related to the dry bulb temperature or the dry-bulb and wet-bulb temperature difference; in the deceleration drying stage, the effect of the dry bulb temperature on the drying rate is greater than the dry-bulb and wet-bulb temperature difference.2.

After the on-site drying test, the shrinkage rate of the veneer before and after drying by Shine veneer dryer is 2-2.5 cm, and the moisture content can be dried to zero, or it can be dried to the moisture you need according to your requirements. It adopts automatic control and frequency conversion control system, which can automatically adjust the transmission speed and temperature according to different veneer thickness and moisture content, so as to achieve the ideal drying effect. Biomass burners can directly burn all kinds of waste wood, saving drying costs.

The 2 deck veneer dryer with biomass burner is currently in operation. It is used to dry rubber wood. It adopts full automatic control and frequency conversion control system. It can automatically adjust the transmission speed and temperature according to the thickness and moisture content of different veneers to achieve the ideal drying effect and accurately control the final moisture content. It avoids the phenomenon that a large number of veneers are over-dried or dried to meet the process requirements. The dried veneer is flat and wrinkle-free. We welcome you to visit the case site.

African veneer bosses often ask me, why is the veneer that is baked in a dryer so damp? To answer this question, there are two main reasons:1. Water absorption of wood itselfWood has a certain range of moisture content, which is adjusted with changes in ambient temperature and humidity. Even after drying, some moisture will still remain in the wood. If the humidity in the storage environment is high, the wood will absorb the surrounding moisture, causing the moisture content to rise, resulting in moisture return.2.

Birch veneer is prone to mildew and blue or red spots after drying. Keeping these two points in mind can help you easily solve the mold problem. First, dry it to about 4-5 moisture, which is equivalent to zero moisture. There will be no mildew problem for 2-3 years. Secondly, it is ideal to place the freshly peeled wet board for 3-5 days before drying. In summer, it needs to be dried after about three days of stacking. If the stacking time is too long, the inside of the board will heat up and spots are prone to appear.

After communicating with us to understand our veneer dryer ,the customer came to our factory for on-site inspection,and finally decided to buy our equipment.Customers have affirmed our veneer drying equipment,especially the heat source - biomass burner.We welcome customers to visit the factory.
