| Why wood veneer should be dried in the plywood produciton ? |
| 1. Wet veneer has a very high moisture content (40%–100%+). It must be dried down to 8%–14%; otherwise, plywood cannot be made: |
| 2.Prevents Blistering/Delamination: Without drying, moisture turns into high-pressure steam during high-temperature plywood hot pressing, blowing the panels apart (commonly known as "blowing" or "popping"). |
| 3.ensures Bonding Strength: Excess moisture dilutes the glue, causing it to bleed through and weaken the bond. On the other hand, over-dried wood sucks up all the moisture from the glue, leaving it "dry" and non-sticky. |
| 4.Prevents Deformation: Removing water beforehand stops the final plywood from warping, twisting, or cracking due to later shrinkage or moisture absorption. |
| 5.Prevents Mold and Decay: The high-temperature drying process kills insect eggs and fungi, preventing mold and discoloration |
What are the Pain Points of traditional roller veneer Drying machine?
|
| 1.Uneven Moisture Content: Due to natural differences between sapwood/heartwood and root/top sections, the dried veneer often ends up "over-dried in some parts but still wet in others." |
| 2.Warping and Cracking: Because veneers are very thin, rapid evaporation causes them to warp, wave, or crack, making it difficult to align and glue them later. |
| 3.Extremely High Energy Consumption: Evaporating tons of water requires massive thermal energy. Drying costs account for 30%–40% of the total production cost, making it highly expensive. in China ,there is an data ,drying 1 cubic eucalyptus veneer cost is RMB130 ,equals $19 .this is very high cost in this high competition days . |
| 4.Heavy Reliance on Manual Labor: Sorting dry sheets from wet ones at the discharge end still largely depends on workers' manual touching and inspection. Working conditions are hot and dusty, making recruitment difficult and human error common. |
Now the most popular veneer drying machine come out !
| 4 advantages lead to the best sale performance |
| 1. High output and Capacity : Daily output of single unit: around 14 to 16 cubic meters Staff arrangement: Two workers can operate 3 to 4 dryers. Each machine supports double feeding and double discharging for uninterrupted cyclic production. |
| 2. Lower Power consumption: 1 pc machine main work power just 3kw (for hydraulic lifting during veneer loading and unloading), daily power consumption about 5 kWh. Lower Steam consumption: Approximately 0.23 tons per batch; 1 ton of steam can serve 3 to 4 machines at the same time. |
| 3. Supreme drying performance : The moisture content of veneers can be controlled at 0%–8% with a shrinkage rate of 2.5–3.0. The veneer features excellent toughness and resists cracking and warping. Its bonding strength is 20% higher than that of traditional press dryers, which reduces glue consumption |
4 Machine low price Compare the traditional roller veneer drying machine ,this type hot press veneer dryer price is very low .reduce the investor invesment largely . |
