Two Drying Technology of Wood Shavings Dryer

also named as wood shavings dryer, is an agricultural machinery. It is used to dry those raw agricultural and forestry materials. If raw materials are high in water content, then the dried products discharged from wood chip dryer are almost all dry. Wood chip dryer has two drying ways: down-flow drying and counter-flow drying. Then, let’s discuss about one by one.
If wood chip dryer adopts the counter-flow drying technology, its temperature is the lowest when water content in raw materials is the highest. Similarly, its temperature is the highest when water content in raw materials is the lowest. When materials lie in the high-temperature stage, they are almost dry and some features are easy to change like activity and crystal structure.
What's worse, energy used for heat supply will increase in amount while decrease in thermal efficiency. For the down-flow drying technology, it can rightly avoid the above situations. Temperature changes of this technology can adapt to the drying technology that water content changes from higher degree to lower degree.
This technology is simpler than the counter-flow drying technology. What's more, drying efficiency and thermal efficiency are relatively high. According to the properties of raw materials, we equip the wood chip dryer with different but suitable lifting boards. They can ensure the heat exchange in wood chip dryer.
To improve the drying efficiency of wood shavings dryer, we should do measures to shorten the staying period of materials in dryer under the premise of effective drying period. Click website to get price!
