Sweet potato residue is the main by-product of sweet potato starch processing. It is extremely rich in protein, carbohydrates, unsaturated amino acids and other substances. In normal times, sweet potato residue can be used as feed for livestock, which can not only improve the appetite of pigs, cattle, sheep and other animals. , but also supplement the required nutrients.

The moisture content of fresh sweet potato residue is generally about 80%, and the moisture content is high, which is not conducive to storage, transportation or reprocessing. After being processed by the sweet potato residue feed equipment, the moisture content can be quickly controlled to about 12%, which meets the water content standard for sweet potato residue feed processing.

Commonly used sweet potato residue feed equipment configuration includes: sweet potato residue dehydrator, heat source equipment, conveyor, sweet potato residue dryer, dust collector, power distribution cabinet, etc. The configuration of the production line is flexible, and the equipment can be increased or decreased according to the actual production requirements of users. A variety of work plans of different specifications.

Sweet potato residue drying feed processing process

After the high-humidity sweet potato residue is processed by the dehydrator, it is directly and quantitatively transported to the tumble dryer by the conveyor. The other end of the layer enters the middle layer for countercurrent drying. The material is continuously and repeatedly raised in the middle layer, in a two-step forward and one-step backward manner. The material in the middle layer not only fully absorbs the heat emitted by the inner layer drum, but also absorbs the heat from the middle layer drum. At the same time, the drying time is prolonged, and the material reaches the expected drying state here. The material travels to the other end of the middle layer and falls into the outer layer. The material travels in a rectangular multi-loop way in the outer drum. The material that achieves the drying effect quickly travels and exits the drum under the action of hot air. The wet material that does not achieve the drying effect cannot be quickly due to its own weight. Moving forward, the material is fully dried in this rectangular copy board, thereby completing the drying purpose.
