How to extract tapioca starch from cassava root? This article will give you a brief introduction.

In all potato production processes (potatoes, sweet potatoes, cassava, etc.), the method of starch extraction is physical separation. In short, this is the process of separating various contents immediately after the material is completely broken. Therefore, in the tapioca starch production line, the procedures are divided into washing, crushing, separation, concentration, dehydration and drying.

The first is the clean and broken parts. After harvesting cassava roots from the field, the cassava should first be cleaned and then sent for further production. The cassava tubers are sent to a dry sieve for dry cleaning to remove dirt attached to the surface, and then wet washed by a paddle washing machine to thoroughly clean them.

After the cassava is fully cleaned, it will be sent to the next process for crushing. The crushing process is divided into two steps: one is to cut the cassava into small pieces with a chopper, and the other is to crush the small pieces of cassava into cassava mash, and then the cassava starch is completely extracted and mixed with other cassava ingredients.

After the crushing section, the next step is the separation and concentration section. The tapioca syrup we get from the previous process contains starch, water, protein, fiber, cell fluid, etc. In this process, we need to separate them one by one and get pure starch milk. First use a centrifugal screen to separate solid fibers, and then use a fine fiber screen to separate fine fibers to ensure high cleanliness. Then root

According to the principle of centrifugal force, a hydrocyclone station is used to remove protein and cell fluid. At the same time, the starch slurry is refined and concentrated in a hydrocyclone. When the required density is reached, it is pumped into the dehydrator.

How to extract cassava starch from cassava root The final step is dehydration and drying. After receiving a certain density of starch slurry from the hydrocyclone, it will be dehydrated using a peeling centrifuge, and finally a wet starch with a moisture content of 38-40% is obtained. The wet starch is not ready for storage, so next we need to use a quick dryer to completely dry the starch to reduce the moisture contentTo 12-14% or according to customer requirements.
