The drying time of dried noodles is an important condition to ensure the quality of dried noodles, and should be no less than 3 and a half hours. The drying time is short, it is easy to cause the noodles to "dry on the outside and damp inside" and shrink on the inside and outside, and even produce crisp noodles. If the drying time is too long, the production efficiency will be low. Drying equipment for dried noodles is classified according to the movement mode of the noodles during the drying process. There are fixed and mobile types; the mobile type is divided into two types: multi-row operation (tunnel type) and single-row operation (cableway type). The moisture conductivity of dried noodles is relatively poor. Therefore, the moisture and heat transfer inside the noodles just coming out of the drying room will not stop suddenly, but gradually weaken until the temperature of the outer layer of the noodles and the outside air are relatively balanced, the moisture will be stable, and the tissue shape will be fixed. This process is called slow-cooking of dried noodles in the process. The slow-down time should not be less than 12 hours.By Twsix noodle dryer, it can control the temperature and humidity exactly
