Jiutian starch slag dryer is based on the research and development for characteristics of raw material such as cassava residue, potato dregs, which can dry all kinds of potato residue below 10% in one time.
The raw material's moisture is about 80%, as for high moisture content, heavy viscosity, with the traditional drying process equipment, drying temperature is high, slag starch Gelatinization chemical reaction, dextrin clogging material particles pores, water evaporation does not come out, the surface of the particles turned yellowish black, "outside the coke within the soft", a serious impact on the sale of dry residue; drying temperature is low, the moisture cannot be drying below 15 % at all, dryer sticky wall, gelatinization, agglomeration, the drying equipment can not do normal production, this will lead to the impaired interest of the customers.
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 residue, tapioca slag, and other agricultural products produce starch production.
Application:Drying potato starch residues for by-product recovery.
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.
