Selection drying process of continuous or intermittent is a very important issue, because many conditions is limited by the equipment.
Continuous drying machine used for the following reasons:
1, if the process before and after it is continuous, select the continuous method;
2, the same material, and the same amount, the use of continuous method can improve thermal efficiency;
3, continuous can make evaporation of water do not appear higher water evaporation peak and is average of the ancillary equipment, so the peak evaporation is smaller than the intermittent and do not waste working hours;
4, continuous drying time is short, so even the process before and after it is also separately the continuous method is beneficial;
5, although it is suitable for Large processing, but the drying time of materials is particularly long, intermittent drying machine is often used;
Using of intermittent drying machine is for the following reasons:
1, the drying process before and after it can not be continuous, and only the drying process can be continuous, using continuous drying machine is do not fit;
2, the output is small and it need replace varieties frequently, the best use is intermittent drying machine;
3, intermittent drying machine is used when errors of water is not allowed;
4, when the material’s supply, remove, equipment transportation and other operation are difficult, using intermittent drying equipment is better;
5, because the structure of this kind of device is relatively simple, so it’s fault is less and it’s price is cheap;
6, when the drying time is long, the drying process can also carry out other operations, so it can improve the operating density.
