If there is no heat carrier in the soybean dregs dryer, the moisture contained in the dried materials cannot be carried out, so the drying of materials cannot be realized quickly and effectively. Therefore, it is very important to choose the right heat carrier for the dryer.
If the disposed material is not allowed to be contaminated,the required temperature is high, the gasifier can be used as heat carrier.This product is energy saving, environmental protection, high thermal efficiency, the generated gas can be cleaned and burned, so the efficiency greatly improved, and can reach the purpose of environmental protection. The gasifier can save at least 20% more energy than the combustion furnace, also greatly on artificial throttling. In general, the gasifier can be operated by a staff member, and it is unnecessary to continuously add coal. In addition, the gasifier can be stopped and used as long as 10 days without working, and can be continued to be used next time.
If the dried object is not allowed to be polluted, and is not allowed to be diluted by air, the heat should be passed through the drying machine rotating cylinder wall into, at this time, the surface heat exchangers, such as central pipes, pipes and sleeves, are installed in the carrier barrel to transfer heat through the metal wall.The heat carrier may be flue gas, water vapor or electric heating. In the dried materials, only through the clean gas, will take away the evaporated water.
There is also a direct heating method, that is, the heat from the metal wall to be dried materials, rather than relying on hot air and materials directly transfer way, such as external heating rotary drum dryer.
Choosing the heat carrier for the bean dregs dryer is not at will, It shall be determined according to the nature of the material itself, so as to create a good drying environment and achieve the desired drying effect.
