Processing cassava into starch requires six steps: cleaning, crushing, filtering, purification, dehydration, and drying. The cassava starch processing equipment used includes dry screens, blade cleaning machines, centrifugal screens, fine residue screens, cyclone groups, and scrapers. Centrifuge, air dryer.
The cleaning process of cassava starch equipment will use dry screening and blade cleaning machines, which are divided into dry cleaning and water washing to remove impurities. The dry screen used in dry cleaning uses the friction and collision between raw materials and between raw materials and equipment to peel off large stones and gravel to achieve the effect of impurity removal; the blade cleaning machine used in water washing uses the principle of countercurrent washing, using the opposite direction of water and raw materials. The movement increases friction and washes away the sediment on the raw materials.
The purpose of crushing is to break the structural tissue of cassava and free the bound starch in the roots. Jinrui’s cassava starch equipment is equipped with a segmenting machine and a filing machine during the crushing stage. The “pre-crushing + filing” design improves the raw material crushing rate and greatly improves the degree of starch extraction.
Since the fiber cost in cassava starch is high, the cassava starch equipment configured by Jinrui adopts two-stage screening. The centrifugal screen and fine residue screen are designed with centrifugal sedimentation raw materials, using centrifugal difference to separate starch and fiber components, and the starch content of the residual starch obtained is less than 0.2%.
4. Purification. Purification is to separate and process the protein, small fibers, cell fluid and other components in the starch milk to improve the purity of the starch milk. The professional starch cyclone group used in the cassava starch purification equipment uses the different centrifugal forces of each component to separate and achieve the purification effect.
Starch milk cannot be dried directly in the air dryer and needs to be dehydrated. The common dehydration configuration of sweet potato starch equipment is a vacuum dehydrator. It uses a vacuum suction filtration design to slurry the starch emulsion on the filter cloth. The water will be removed through the filter cloth to obtain wet starch with a moisture content of about 40%, which meets the requirements of starch drying. condition.
Drying is to better preserve tapioca starch, and the air flow dryer uses heat transfer between objects to achieve the drying function. Hot air is introduced into the airflow dryer, and the starch will rise with the hot air. During the rising process, the hot air will take away the excess starch moisture, and then use the cyclone recovery device to collect the dry starch.
