Precautions for the use of hf timber dryer
Modern dryers began to use fixed-bed dryers with intermittent operation. In the middle of the 19th century, the use of tunnel dryers marked the development of dryers from intermittent operation to continuous operation. The rotary drum dryer better realizes the agitation of the granular materials, and the drying capacity and strength are improved. Some industries have developed continuous operation dryers that meet the requirements of the industry, such as hf timber dryers in the textile and paper industries. So, what should be paid attention to when using hf timber dryer? Let's take a look at it.
Attention should be paid to the use of hf timber dryer:
1. The hf timber dryer is equipped with a spray device to make the wood achieve the effect of steaming. The moisture of the wood is discharged from the inside to the outside in stages, and the dried wood will not appear deformation, internal cracking, end cracking, etc.
2. The hot air recovery system can be added to recycle the discharged hot air, speed up the air flow in the drying room, speed up the drying time, and improve the utilization of heat energy.
3. Drying of hf timber dryer wood is a matter of speed, so the temperature should not be too fast, otherwise the wood will crack, and it is necessary to pay attention to the stacking of wood, pay attention to uniform heating, and also consider the wind The direction of flow allows hot air to circulate from the stacked wood.
4. Using hf timber dryer, it can be dried to any final moisture content required, and is not restricted by natural conditions; it has more mature drying theory and process technology, which can ensure the drying quality; compared with air drying, the drying cycle is short, and the production High efficiency, small footprint; less complex equipment, long service life, safe and reliable, and good economic effect.
