How many steps during cassava flour processing?

Cassava flour is a gluten-free, wheat flour alternative that’s made by grating and drying the fibrous cassava root (yuca) and non-allergenic. It’s gluten-free, grain-free and nut-free; low in calories, fat and sugar; and inexpensive, sustainable and easy to grow.

It's one of the most valuable sources of nutrition for more than 500 million people living in Africa, Asia and Latin America. Compared to many other crops, cassava requires a low amount of energy to produce and yields a high amount of edible crop per plant, making it one of the world’s most valuable stable crops. In addition, nearly every part of the plant can be used in some way. In future, there is a bright market for cassava flour processing.

This picture is mainly introduced the cassava flour processing line and the main machine

You can start your own cassava flour processing in simple steps: harvest the roots, peel and wash the roots, grate the roots, press and dry the roots, and mill and sift your flour.

Cassava flour processing introduction：

Step 1: Harvesting

Harvest matured cassava from the farm and load it to the high quality cassava flour (HQCF) processing shed immediately. If the quantity of cassava harvested can not be carried in the same day for logistic reasons do not detach the cassava from the stem and leaf until the vehicle to carry it is ready. That is to say, fermentation will not occur if the cassava is still attached to the leaf and stem even if it has been uprooted. But care must be taken not to bruise the cassava when uprooting it.

Cassava washing and peeling machine

Step 2: Washing and peeling cassava

Our cassava peeler could handling large capacity of cassava and well cleaning. This cassava peeler machine is with stable operation and easy maintenance etc. 1. peeling 2. washing 3. do not hurt the material 4. material to the next stage automatically.

Grinding machine

Step 3: Grinding

The tuber is grinded and become low broken percentage . That means 50% cassava flour is not separated and combined with fiber. In the rasping process, should add process water to dilute slurry. the potato slurry in the collection trough is pumped in to desanding cyclone. Don't make the cassava flour dissociate and make the cassava flour combine with fiber. So the special design of rasper is vital for flour fineness and freeness.

Step 4: Desanding

In the desanding process, sands and sawtooth etc coarse particle will be removed from cassava slurry. This unit is made of ceramic cyclongnetts, sands collection tank, automatic desanding valve and back flush device. back flush avoid cassava flour loss in desanding process. Desanded slurry is sent to dewatering unit.

We use filter presser to dewatering and detoxification process

Step 5: Dewatering

Because there is hydrocyanic acid toxic substance in cassava peels. In this unit, we use filter presser to dewatering and detoxification process.When slurry reaches to certain liquid position in slurry tank, start to dewater by filter presser. Then transport the material to cassava flour drying procedure by belt conveyor.

Drying machine

Step 6: Drying

Dewatered cassava flour cake contains high moisture to 45~50%, which can’t enter into flash dryer directly and will be mixed with dry flour and reduce the moisture to 38%, then transported to feeding port of flash dryer by conveyer belt, pass through feeder and enter into raiser. The heat source of flash dryer is steam heat exchanger. Wet cassava flour is heated by hot wind and water is steamed. After drying, cassava flour and air are separated in cyclone separator. At the bottom of cyclone separator, it is closed by air closer. after wet air leave cyclone separator , which is discharged in to atmosphere. Collected cassava flour is transported to vibration sieve unit; the coarse particulate matter is sieved out. The sieved cassava flour is transported to hopper for storing and cooling.

Automatic cassava flour packing machine

Step 7: Automatic packing machine

1. Automatic weighing and calculating

2. Large adjustable weighing scope from 5-50kg

3. Hand seal, Packing cassava flour in different bags.
