A Comparison between Two Different DryersA wood pelletizing line contains many processes, an indispensable one of which is the drying process. It is known that the raw materials are still maintain relatively high moisture content, about 60%, after crushed, though the size basically met the requirements of pelletizing. Such high moisture certainly cannot be put directly into the pellet mills, because the pellets made out in such a way would not meet the national standard. At this time, a dryer will be helpful.
No matter it is biomass briquettes or wood pellet fuel that you are about to produce, the dryer plays an essential role in your technological process. There are mainly two kinds of dryers for the two different uses mentioned above – the dryers for biomass briquetting and the rotary drum dryers for wood pellet mills.
Both the two types of dryers above can precisely set the air temperature with fantastic thermostatic control mechanism, to ensure qualified moisture. Compared with dryers for biomass briquetting, the rotary drum dryers have more choice on fuel for heating, since rotary drum ones can use gas or oil.
If you are considering buying a dryer, GEMCO dryers will be your best choice without any doubt.
