Production process of fully automatic cassava starch processing equipment

The fully automatic cassava starch processing equipment is divided into six processes: cleaning process, crushing process, screening process, refining process, dehydration process, and drying process.
Mainly including dry screen, blade cleaning machine, segmenting machine, file grinder, centrifugal screen, fine sand screen, cyclone, scraper centrifuge, vacuum dehydrator, airflow dryer and other equipment.
Such a set of fully automatic cassava starch processing equipment can continuously produce cassava starch, and the produced cassava starch can be packaged and sold!

Process 1: Cleaning process
The equipment used in the cleaning process of the fully automatic cassava starch processing equipment is dry screen and blade cleaning machine.

The dry screen of the first-level cleaning equipment adopts a multi-threaded structure design to push the material forward to remove impurities such as soil, sand, small stones, weeds, etc. attached to the cassava raw materials. The material cleaning distance is long, the cleaning efficiency is high, there is no damage to the cassava skin, and the starch loss rate is low.

The paddle cleaning machine of the secondary cleaning equipment adopts the countercurrent washing principle. The water level difference between the material and the cleaning tank forms a reverse movement, which has a good cleaning effect and can effectively remove impurities such as mud and sand in the sweet potato raw materials.

Process 2: Crushing process
The equipment used in the crushing process of the fully automatic cassava starch processing equipment is a segmenter and a file grinder.

The segmenter of the primary crushing equipment pre-crushes the sweet potato raw materials at a high speed and breaks the sweet potatoes into sweet potato pieces. The blade of the Jinrui segmenter is made of food-grade 304 stainless steel, which is corrosion-resistant and has a long service life.

The file grinder of the secondary crushing equipment adopts a two-way filing method to further crush the sweet potato pieces. The material grinding coefficient crushing rate is high, the combined starch free rate is high, and the raw material crushing rate is high.

Process 3: Screening process
The equipment used in the screening process of the fully automatic cassava starch processing equipment is a centrifugal screen and a fine residue screen.

The first step of the screening process is to separate starch from potato residue. The centrifugal screen used is equipped with an automatically controlled forward and back flushing system. The crushed sweet potato starch slurry is screened by the gravity and low centrifugal force of the sweet potato starch slurry, so as to achieve the effect of starch and fiber separation.

The second step is to use a fine residue screen for re-filtration. Cassava has a relatively high fiber content, so it is necessary to use a fine residue screen again to filter the cassava starch slurry for a second time to remove the residual fiber impurities.

Process 4: Refining process
The equipment used in the refining process of the fully automatic cassava starch processing equipment is a cyclone.

This process generally uses an 18-stage cyclone group to remove fine fibers, proteins and cell fluids in the cassava starch milk. The whole set of cyclone groups integrates multiple functions such as concentration, recovery, washing and protein separation. The process is simple, the product quality is stable, and the cassava starch produced is of high purity and high starch whiteness.

Process 5: Dehydration process
The equipment used in the dehydration process of the fully automatic cassava starch processing equipment is a vacuum dehydrator.

The part of the vacuum dehydrator that contacts the cassava starch material is made of 304 stainless steel. After dehydration, the moisture content of the starch is less than 38%. It has a built-in spray water system, automatic control, and intermittent flushing to ensure that the filter is not blocked. The filter tank is equipped with an automatic reciprocating agitator to prevent starch deposition. At the same time, it realizes automatic unloading and reduces labor intensity.

Process 6: Drying process
The equipment used in the dehydration process of the fully automatic cassava starch processing equipment is an airflow dryer.

The air dryer adopts a negative pressure drying system and a dedicated material cooling system, with high heat exchange efficiency, which can achieve instant drying of sweet potato starch. The moisture content of the finished sweet potato starch after drying by the airflow dryer is uniform, and the loss of starch materials is effectively controlled.
