Straw will be produced after the crops are harvested. Straw recycling is used for many purposes such as papermaking raw materials, biomass fuel, livestock feed, artificial board, etc. It has good economic and environmental benefits. However, straw is difficult to preserve. Seasonal crop straws have a certain amount of water content. Long-term accumulation will affect their quality and market price. How to solve it?
Straw storage requires straw drying first, so a straw dryer is essential. The moisture content of the straw after drying is about 12%, which is convenient for storage and long cycle. Straw drying uses high-temperature drying, and there are different technical design schemes according to the specific straw processing technology. For straw biomass fuel, direct high-temperature drying is used to forcefully reduce the water content, and straw feed production requires straw palatability, therefore, it is necessary to clean the straw and maintain the taste.
How to deal with the straw, it first needs to be dried and upgraded by the dryer to facilitate storage and transportation. Then it is used for straw feed production, straw biomass pellet fuel production or straw papermaking and other process production with quality assurance. Each process already has a mature technical process, equipment market supply and a stable and expanding demand market system. The economic and environmental benefits of straw recycling are obvious.
