Every year, a large amount of sweet potatoes are processed into vermicelli, and the remaining sweet potato residue is mostly buried, which not only pollutes the environment but also wastes resources. In fact, sweet potato residue is rich in nutrients, but it is not easy to preserve. A sweet potato residue dryer can effectively solve this problem. So, what can dry red potato residue be used for?

  1. Feed:sweet potato residue has high nutritional value, with crude protein, crude fat, and crude fiber content all exceeding 20%. Therefore, sweet potato residue is often used to make feed for cows, sheep, pigs, and other animals.

  2. Organic fertilizers:sweet potato residue is rich in small molecule organic acids. It can increase soil acidity, improve soil fertility, and promote plant growth.

  3. Paper making:sweet potato residue can also be used in industrial fields such as papermaking, cosmetics, food, and medicine.

  4. Biomass fuel:after drying, it can also be made into pellets of biomass fuel.
