Starch residue is the residue of peas, broad beans, potatoes, sweet potatoes, and other raw materials to produce starch food. Due to the different raw materials, the nutritional content is also different. The water content of fresh powder residue is very high, up to 80%~90%. Because it contains soluble sugar, it is easy to cause lactic acid bacteria to ferment and have a sour taste. The longer the storage time, the greater the acidity, and it is easy to be contaminated by molds and spoilage bacteria and deteriorate, loss of feed value. Therefore, it needs to be dried when used as feed.
Jiutian potato dregs drying production line adopts "dehydration + drum drying + pulse air drying ", an effective solution to the traditional dryer which can not dry cassava, potato residue problems, drying material with the perfect color, good quality, production line of energy-saving and environmental protection, with safe and stable operation, which praised by many new and old customers.
Materials:Widely used for drying potato residue, sweet potato dregs, cassava pulp, tapioca slag, and other starch residue.
Application:Drying starchy processing residues for feed and industrial reuse.
Material Flow:
Material with 75–85% moisture is first partially dewatered to about 68%, then conveyed into the rotary dryer for downstream drying. Inside the drum, lifting plates and mixing blades continuously disperse and crush the material, ensuring full heat exchange with hot air. Moisture is reduced to about 35% and discharged by screw conveyor.
The semi-wet material is then crushed to below 1 mm and enters a pulse air drying system, where moisture is rapidly reduced to about 14% within 3–10 seconds. The dried powder is collected by a cyclone and pulse bag filter, completing the drying process. A drum cleaning device prevents material adhesion to the inner wall.
Air Flow:
Air heated by the hot blast stove to 600–850°C enters the dryer for heat exchange and moisture evaporation. After cooling to 55–85°C, exhaust gas is purified by cyclone and pulse dust collectors before meeting emission standards.

Intelligent control ensures uniform final moisture, bright color and stable quality, meeting feed raw material requirements without nutrient loss.
Built-in mixing and dispersing system improves heat exchange, increases drying capacity by 50%, and reduces fuel consumption by about 30%.
Sealed insulation design minimizes heat loss, with low failure rate, low maintenance cost and reliable long-term operation for feed plants.
Dried residue becomes fine, uniform powder and can be directly connected with crushing, mixing, pelletizing and packing systems for pellet feed production.
From solution design to equipment manufacturing and on-site installation and commissioning, Jiutian provide complete one-stop services. The equipment is exported to over 100 countries including UK, Russia, Malaysia, the Philippines, Italy, Israel, Indonesia, Malaysia, Ethiopia, Nigeria, Congo, South Africa, Pakistan, India, Egypt, etc. Looking forward to cooperating with you.
