How to ensure that cassava starch is always of optimal quality, while saving costs? The answer lies in the precise and efficient humidity control of the Hydronix sensor! The following article will analyze each stage of cassava starch production in detail. It will also introduce modern moisture control methods, helping manufacturers understand the importance of maintaining standard moisture levels throughout the process.
Moisture Control: Why Is It So Important?
You definitely don’t want your products to be attacked by mold or bacteria, right? Excessive moisture during cassava starch production can create ideal conditions for these harmful agents to grow, reducing product quality and affecting consumer health.
What’s the simple solution? Maintaining moisture at the optimal level will help the cassava starch retain its color, flavor, and long-term durability. More importantly, the product will be easier to preserve and meet the strict standards of international markets, opening up export opportunities without facing quality issues.
Cassava Starch Production Process at the Factory
a. Pre-processing Raw Materials
The production process begins with the purchase of fresh cassava roots, followed by screening and washing to remove dirt and unwanted impurities. The cassava that meets the standards will be peeled and finely crushed to increase surface area, facilitating the starch extraction process.
b. Grinding
After pre-processing, the cassava is ground and finely milled to maximize starch yield. This is a critical step because if the cassava is not ground finely enough, starch extraction efficiency will decrease. The fineness of the material also affects the moisture content in the starch, impacting moisture control in the subsequent stages.
c. Soaking and Residue Separation
After grinding, the cassava starch mixture is soaked in water to create a liquid solution, helping to remove impurities and obtain the purest starch. The residue separation stage can be done using two methods:
-
Sedimentation method: The soaked cassava solution is placed into a large sedimentation tank. Starch, being heavier, settles at the bottom, while lighter impurities float to the surface. The manufacturer can easily collect the starch from the bottom of the tank.
-
Centrifugal method: The starch mixture is placed in a high-speed centrifugal machine. The strong centrifugal force helps separate the starch from impurities more effectively, shortening the processing time compared to traditional sedimentation.
d. Drying and Sieving Starch
After sedimentation and cleaning, the cassava starch still contains a considerable amount of moisture, so it needs to be dried to ensure quality. After drying, the starch moisture must reach a standard level of below 13% (according to TCVN 9934:2013, ISO 1666:1996) to ensure product durability and prevent spoilage during storage.
e. Packaging
The dried cassava starch is packaged according to the weight suitable for customer needs. The entire packaging process is carried out in a sealed environment, ensuring hygiene and preventing moisture reabsorption, helping maintain product quality during storage and transportation.
Modern Methods for Controlling Cassava Starch Moisture
Moisture control in cassava starch production is essential to ensure consistency and product quality. Traditional methods of sampling and manual measurement often do not provide high accuracy, requiring multiple samples and failing to ensure consistency throughout the process.
Today, cassava starch factories can apply automated solutions for moisture monitoring. A prime example is the Hydro-Mix XT-FS sensor from Hydronix – an immersion sensor that can be installed under the conveyor belt to accurately measure moisture content in the entire batch of material after drying. Moisture data is directly transmitted to the monitoring screen, allowing manufacturers to evaluate quality and adjust in a timely manner.
Advantages of Hydro-Mix XT-FS
-
Direct measurement on the conveyor belt: Continuously monitors moisture throughout the entire batch, ensuring accurate, consistent results without the need for repeated sampling.
-
Food safety standards compliance: Designed to meet food hygiene regulations, ensuring that the cassava starch is not contaminated during production.
-
Easy installation and maintenance: Can be directly integrated under the conveyor belt, making it convenient for inspection and maintenance when necessary, reducing production downtime.
