The working principle of straw dryer

ZHENGZHOU, China - May 26, 2022 - PRLog -- The straw dryer is the main equipment for the recycling of agricultural straw drying resources. After the wet straw is crushed, dried, pelletized, briqueted, packaged, or baled, it can be used as feed or fuel to increase its economic value.

The straw dryer is suitable for barley straw, oat straw, wheat straw, rye straw, rice straw, sorghum straw and corn straw, as well as potato vines, legume straws (including soybean straw, broad bean straw, pea straw, cowpea straw, lupin straw, etc.) Bean straw and peanut vines and other materials) drying. Zhengzhou Jiutian optimizes the drying process technology according to the characteristics, output size, application requirements, cost control and ease of operation of each straw.

Working principle:

The pulverized straw enters the inner layer of the rotary drum from the feeding device to realize downstream drying. One end enters the middle layer for counter-current drying, and is repeatedly raised in the middle layer, in a two-step forward and one-step backward mode; then the middle layer can fully absorb the heat emitted by the inner layer drum and the middle layer. At the same time, the drying time is prolonged, and the straw reaches the expected drying state here. The straw travels to the other end of the middle layer and falls into the outer layer, and travels in a rectangular multi-loop way in the outer drum. The straw that achieves the drying effect quickly travels and exits the drum under the action of hot air, and the wet straw that does not achieve the drying effect cannot travel quickly due to its own weight, and fully dry in this rectangular plate, thus completing the entire drying process. Subsequent processes such as granulation/briquetting, packing/bundling, etc. can be prepared.
