In the different section of cassava starch prodcution line, the cassava starch production equipment will have different effects, so here are nine sections in the whole prodcution line.
(1) Conveying / loading
The cassava is sent to the trough and pumped to the stone remover where the stone and other heavy objects are separated, the cassava starch production equipment is the primary cleanup role.

(2) Cleaning equipment
In order to achieve a better cleaning effect, the secondary cleaning machine of cassava starch production equipment is required. The washed cassava is then transported to the temporary hopper via a tilt belt conveyor.
(3) Unloading spiral
The specially designed discharge port is attached to the discharge conveying screw. The speed of the discharge screw is not adjustable, so the production capacity of the cassava starch production equipment can be fitted by this screw. The outlet of the conveying screw is attached to the honing machine.

(4) Rasping equipment
Since the rasping efficiency is critical to the overall yield of the system, the cassava starch production equipment is specifically designed to reach the highest efficiency. Europe advanced accessories are introduced by kaifeng sida Group to improve the starch extraction rate of the equipment.
(5) Sand removal equipment
The cassava starch emulsion from the rasping machine is conveyed by a screw pump to a sand removing cyclone to remove sand. The working principle of this cassava starch production equipment is specific gravity separation.
(6) Fiber extraction equipment
The starch emulsion from the sand removing unit is sent to the extraction unit, and the extraction unit is integrated, including three conical rotating centrifugal sieves, a fiber pump, and a defoaming pump. The fibers are washed and divided in a countercurrent manner by the cell fluid from the multistage cyclone in this 3-stage sieve. The separated fibers enter cassava starch production equipment dewatering screen for dehydration.
(7) Refinement equipment
The starch milk from the first stage centrifugal sieve enters a 16-stage concentrated cyclone washing unit, and the process water is pumped from the other end of the cyclone station to wash the starch in a countercurrent manner. The whole cyclone station can consist of three parts. First, the starch milk is dehydrated and concentrated by a focused cyclone station, and the concentrated starch milk enters the subsequent 13-stage washing unit, and the overflowed cell liquid enters the recycling cyclone station. Starch contained therein is recovered. The starch milk from the cyclone station is pumped into a stainless steel cassava starch production equipment.
(8) Starch dehydration equipment
The moisture content of the starch milk coming out from the cyclone station is too large to be directly dried. Therefore, the starch milk should be dehydrated first, so that the moisture content of the starch is about 40%. The working process of this cassava starch production equipment is:
the starch pump is pumped from the starch milk temporary storage tank into the vacuum dehydrator tank, and a water pipe is connected to the starch milk pipeline, and the starch milk is diluted to a certain concentration with the process water. The vacuum pump creates a negative pressure in the vacuum drum. When the starch emulsion is in contact with the vacuum drum of this cassava starch production equipment, the starch milk is sucked on the drum surface, the filtrate is sucked into the filtrate separation tank and pumped away from the filtrate, and the filter cake is scraped off by the scraper. The food-grade conveyor belt is used to transport the feed hopper of the intake air dryer.
(9)Starch drying equipment
The final cassava starch production equipment is flash dryer whose main function is to dry wet starch to a moisture content of 14%.
