Cassava Starch Vibro Sifter

Cassava Starch Vibro Sifter uses vibration and a screen structure to separate impurities, coarse particles, and qualified cassava fines from cassava starch granules, thereby improving the purity and quality of cassava starch. Its mesh size typically ranges from 80 to 200 mesh, and the screen size can be adjusted to meet cassava starch production needs. A small-sized Cassava Starch Vibro Sifter has an hourly output of approximately 0.5-2 tons, while a medium-sized Cassava Starch Vibro Sifter can reach 2-5 tons.

Cassava starch is a highly viscous starch extracted from the tuberous root of the tropical shrub cassava. In the food industry, it is used to make pearls in bubble tea, taro balls, mochi, crystal shrimp dumpling wrappers, meatballs, fruit pie fillings, cake fillings, and thickening soups and sauces. In the industrial sector, cassava starch is also used in a variety of applications, including papermaking, textiles, adhesives, and biodegradable materials.

What are the benefits of using a Cassava Starch Vibro Sifter to screen cassava starch?

Cassava starch easily absorbs moisture and forms clumps, has a fine particle size, and requires high purity. Conventional screening equipment is prone to clogging and uneven screening. The Cassava Starch Vibro Sifter specifically addresses these issues. Its high-frequency vibration principle quickly breaks up starch clumps, preventing them from accumulating and deteriorating. It also precisely separates impurities and starch particles of varying sizes, meeting the diverse demands for cassava starch purity and particle size uniformity. Structurally, it features a dedicated anti-sticking screen and sealing device. The anti-sticking screen reduces starch adhesion and clogging, ensuring screening efficiency, while the sealing structure prevents dust from forming, minimizing raw material waste and preventing dust pollution.

What types of vibrating screens are available for the Cassava Starch Vibro Sifter?

In cassava starch processing, the Cassava Starch Vibro Sifter is a core device for ensuring product fineness and purity. Three main types are available: Linear vibrating screens offer high throughput and a sturdy structure. They are suitable for initial impurity removal and coarse screening of cassava starch raw materials, efficiently processing large volumes of initial slurry. Circular vibrating screens utilize three-dimensional elliptical vibrations to achieve high screening accuracy and outstanding efficiency. They are ideal for mid-stage grading of cassava starch, effectively separating starches of varying fineness and ensuring uniformity in the finished product. Ultrasonic vibrating screens are specifically designed for screening highly viscous and fine cassava starch. The high-frequency vibrations of an attached ultrasonic system completely eliminate the problem of cassava starch easily clogging the mesh, making them ideal for producing ultrafine refined starch with a mesh size of 150 or higher.

Choosing a Screen for the Cassava Starch Vibro Sifter

The varying fineness of cassava starch directly determines the screen selection for the Cassava Starch Vibro Sifter, as different applications require different starch fineness levels. For example, cassava starch used in general food processing (such as pastries and vermicelli) typically requires a fineness of 80-100 mesh. In this case, an 80-100 mesh nylon screen is needed to ensure starch fineness while preventing low screening efficiency. Cassava starch used in high-end cosmetic raw materials or pharmaceutical excipients requires a finer fineness of 120-150 mesh. Therefore, a 120-150 mesh high-precision stainless steel screen is used to ensure thorough impurity removal and starch purity. Cassava starch used in industrial adhesive production has relatively loose fineness requirements, and a 60-80 mesh screen can meet the requirements, filtering out large impurities while increasing screening speed.

Main Components of the Cassava Starch Vibro Sifter

The core structure of the Cassava Starch Vibro Sifter consists of a vibrating motor, screen frame, screen, shock absorber, and frame. The vibrating motor is the core power source, driving the screen frame through eccentric vibration, which directly affects screening efficiency and accuracy. The screen frame, which secures the screen mesh, is typically made of stainless steel, which is corrosion-resistant, easy to clean, and prevents starch contamination. The screen mesh material and mesh size are selected as needed: nylon mesh is suitable for general food grade, while stainless steel mesh is suitable for high-end or pharmaceutical grade. The shock absorber, typically a spring structure, is installed between the screen frame and the machine frame to reduce vibration impact on the frame, reduce operating noise, and extend equipment life. The frame is the supporting structure and requires sufficient stability to ensure that the equipment does not deflect during high-frequency vibration.

Cassava Starch Vibro Sifter Applications

The Cassava Starch Vibro Sifter is widely used throughout the entire cassava starch processing chain and in related applications. During primary processing, it removes impurities such as crude fiber and sediment from starch, paving the way for subsequent purification. During refined starch production, it can be graded and screened to produce finished products of varying fineness, meeting the needs of the food, cosmetics, and pharmaceutical industries. During the production of starch derivatives (such as starch sugar and modified starch), it can pre-treat raw starch to ensure purity and avoid compromising the efficiency of subsequent chemical reactions. Furthermore, some smaller devices are suitable for laboratory use, providing screening services for cassava starch R&D experiments.

The Cassava Starch Vibro Sifter is a core screening device in cassava starch production. Using a vibrating motor to drive the screen, it efficiently separates starch particles of varying particle sizes, significantly improving product purity and yield. Suitable for both primary processing and refining, this device meets the needs of diverse applications across the food, pharmaceutical, and industrial sectors. Featuring high screening accuracy, high throughput, energy efficiency, and a high degree of automation, it can be flexibly adapted to production lines of varying sizes, making it a key tool for optimizing starch quality and production processes.
