What is the primary processing of cassava?

The primary processing of cassava in multiple cassava processing lines is the cleaning section. After cassava tubers are harvested from farm field, they are attached with a lot of impurities like soil, stones, grass, etc. The first step is to remove these impurities. Main equipment that are used in the cleaning section include a dry sieve, a paddle washer, and a cassava peeler.

The working flow of the primary processing of cassava: Firstly cassava roots will be put into feeding hopper by wheel loader. At bottom of the hopper, there is vibrate device to prevent cassava blocking and ensure uniform feeding of raw cassava. And then cassava will drop down on the belt conveyor and be transported to dry sieve machine. After the dry sieve’s cleaning, cassava tubers will be conveyed to the paddle washer for washing, then will enter a cassava peeler for peeling.

The working flow of the primary processing of cassava

The dry sieve machine is necessary equipment for the primary processing of cassava, used to remove impurities that are attached on cassava roots surface. When it’s running, cassava roots will be pushed forward from inlet to outlet by inner screw. By friction effect between cassava and equipment, impurities will be removed and then drop down through the gap between steel bars. If cassava are attached with wet clay, spray water pipe could be installed at outlet of the machine. For clients who just wanna produce a single cassava product for animal feed use, then just one dry sieve machine is enough for primary processing of cassava. While if they would like to process the end product for human consumption, a paddle washing machine is needed.

Cassava cleaning machines

The paddle washer machine for the primary processing of cassava is employed to wash cassava roots after dry sieve cleaning. When cassava drop into water slot, inside paddle will propel cassava from inlet to outlet. The bottom plate of water slot is mesh screen, which can separate sand and cassava gradually during washing process. According to different capacity requirement, the paddle washer machine can be designed as single slot or multiple slot. If you are producing edible cassava flour or garri, given that the food safety, a cassava peeling machine is also required for the primary processing of cassava.

The cassava peeling machine for the primary processing of cassava plays a role in removing the two poisonous layers of cassava tubers. Made of stainless steel and designed with sand rollers, our peeling machine has better peeling effect than other kinds of peelers in the market. The sand roller is composed of sand paper and stainless steel roller. After long time use, you can just change sand paper to keep peeling effect, no need to change the complete roller, which can save running cost.

The above are equipment used for the primary processing of cassava. Apart from these machines, Henan Jinrui company can supply complete machinery for cassava products like garri, cassava flour and cassava starch. If you have such a plan to set up a cassava factory, feel free to contact us any time.
