Fufu is a popular staple food in West and Central Africa made out of cassava, plantains or yams. The improved production process is starts by
peeling of roots, washing, cutting into pieces and steeping in water to ferment for 3-4 days. The fermented mash is pounded or simply washed
over a fine sieve to remove fibre and the water expelled from the starch extract by pressing through muslin cloth to produce fufu.
The air drying system is widely used for powder drying, and the humidity is controlled between 14% and 20%. Mainly used for canna starch,
sweet potato starch, tapioca starch, potato starch, wheat starch, corn starch, pea starch and other starch production enterprises.

Advantages of airflow dryer
1.Fully considered each factor of turbulent flow, cyclone separating and heat exchange.
2.Parts contact with starch is made of stainless steel 304.
3.Energy saving, moisture of product stable.
4.The moisture of starch is very stable, and varied 12.5%-13.5% by automatic control which can control the moisture of starch by controlling
feeding quantity of steam and wet starch.
5.Less starch loss from wind exhausted.
6.The complete solved plan for a whole flash dryer system .

The working principle of airflow dryer
The cold air enters the radiator plate through the air filter, and the hot air flow after heating enters the dry air pipe. Meanwhile, the wet material
enters the hopper of the feeding unit from the wet starch inlet, and is transported into the hoist by the feeding winch.The hoist rotates at high
speed to drop the wet material into the dry duct, so that the wet material is suspended in the high speed hot air stream and heat is
exchanged.After the material is dried, it enters the cyclone separator with the airflow, and the separated dry material is discharged by wind
winding, and the finished product is screened and packed into the warehouse. And the separated exhaust gas, by the exhaust fan into the exhaust
gas duct, into the atmosphere.
