Straw is an important byproduct of agricultural production. It is rich in organic matter and nutrients and can be used as fertilizer, feed, fuel and industrial raw materials. However, improper straw treatment, such as open-air burning, not only wastes resources, but also produces a large amount of harmful gases and particulate matter, seriously polluting the atmosphere and having a negative impact on the soil and ecosystem.
The moisture content of freshly harvested straw is high, which is not conducive to subsequent processing and transportation, and needs to be dried first. Straw dryer is an equipment used to quickly reduce the moisture content of straw, suitable for drying various high-humidity biomass raw materials.
The straw dryer is mainly composed of heating equipment, drum, induced draft fan and hot air circulation system, dust removal and exhaust gas treatment system, unloading and conveying system, etc. The straw enters the dryer through the feeder and is fully exposed to hot air in the drum to evaporate the moisture. The hot air drying reduces the moisture content of the straw to below 15%. The dried straw is sent to the storage or processing area by a belt conveyor. It can be further processed by equipment such as biomass pellet machine, biomass briquette machine, carbonization equipment, etc. according to needs.
Application of dried straw:
Agricultural field:
Return straw to the field: crush it and return it to the field to improve soil fertility.
Feed processing: make straw into high-quality forage to improve feed utilization.
Organic fertilizer production: crush straw and use it as organic fertilizer raw material.
Industrial field:
Biomass fuel production: press straw into pellet fuel for power generation or heating.
The straw dryer promotes the utilization of straw resources and promotes the sustainable development of agriculture. Jiutian is a professional straw dryer supplier, if you are interested in our straw dryer equipment, please feel free to contact us.
