The primary limitation of the recycling of fresh sweet potato residue is water, fresh sweet potato residue is easy to spoil and deteriorate, low utilization rate, and pollute the environment. Fresh sweet potato residue can be directly dehydrated and dried, or dried after fermentation. The fermented sweet potato residue after drying is also well maintained in nutrition and taste.
The fermented sweet potato residue dryer is also dried by high temperature using a three-cylinder dryer. The potato residue dryer has a small footprint, large processing capacity, strong drying capacity, and a more precise temperature control system to maintain the taste of fermented feed. And nutrients are well protected. The improved fermented sweet potato residue dryer further reduces the secondary pollution of the sweet potato residue in the drying process, and better improves taste of the dried potato residue.
The improved fermented sweet potato residue dryer is mainly embodied in the pre-purification system of the heating system and the introduction technology of the clean fuel. The current heating system of the rotary dryer uses clean energy such as natural gas, biogas and biomass fuel etc. and Steam drying can be used according to the resources of the customer, or electric drying can be used to further reduce the heating medium and the fermented feed. The secondary pollution of the fermented sweet potato residue during direct heat exchange promotes the improvement of the cleanliness and taste of the dried sweet potato potato residue.
