Beyond Dried Cassava Chips: How Technology Enables Production of Premium Starch & Flour?

For many cassava processors, producing dried cassava chips has been a reliable, yet increasingly competitive, business with slim margins. To unlock higher value, forward-thinking producers are turning to more profitable products: premium cassava starch and high-quality cassava flour. While chips require a relatively simple process of cleaning, chipping, and drying, achieving the exceptional purity of starch or the fine consistency of flour demands advanced, purpose-built processing technology and a strategic upgrade of your production line.

In this article, Henan Jinrui explores how modern technological solutions enable this vital transition, focusing on the core processes that define success in the starch and flour markets.

Cassava starch processing equipment

Core Technology for Premium Starch Production

To produce high-quality cassava starch and move beyond dried chips, a modern processing line must master three core technological stages: efficient grating, multi-stage purification, and precision drying.

1. Efficient Grating: Maximizing Starch Liberation

The process begins with disrupting the cassava root's cellular structure to release the maximum amount of starch granules, which is the foundation for a high extraction rate. Advanced grating technology is crucial here. For instance, Henan Jinrui's processing line employs a two-stage grating system. This design ensures a thorough and fine breakdown of the roots, achieving a grating rate of over 98% and setting the stage for optimal starch recovery in the subsequent stages.

2. Multi-Stage Purification: Ensuring High Purity

This is the technological heart of producing premium cassava starch. Simple washing is insufficient; achieving high purity requires sophisticated separation. This is accomplished using a hydrocyclone station. Henan Jinrui's system often features an 18-stage hydrocyclone stations that integrates three key functions: purification, concentration, and refinement. It uses centrifugal force to progressively remove fine fibers, soluble proteins, and other impurities from the starch milk. This advanced purification process consistently yields starch with a high concentration, reliably reaching 22°Bé, which meets stringent national and industrial quality standards.

3. Precision Drying: Preserving Functional Quality

The final step is to dry the pure starch slurry without damaging its functional properties. Gentle yet efficient drying is key. Henan Jinrui utilizes a flash dryer (or pneumatic dryer) for this critical stage. This equipment rapidly dries the starch in a controlled hot air stream within seconds. This method not only ensures high production efficiency but also strictly controls the final moisture content to a stable 12-14%.

Cassava flour procesisng equipment

Core Technologies for High-Quality Cassava Flour Production

Moving your business from dried cassava chips to the high-quality cassava flour market demands technology focused on superior food safety and texture. The core of this upgrade lies in three precise stages: thorough peeling, fine milling, and gentle drying.

1. Thorough Peeling: Ensuring Hygiene & Color

The foundation of premium flour is impeccable raw material preparation. Efficient removal of all soil and outer skin is non-negotiable for food safety and achieving the desired product whiteness. Henan Jinrui's peeling machine is designed for this critical first step, achieving a peeling rate of up to 96%. An integrated water spray system continuously cleans the roots during operation, ensuring the purer, safer final flour production.

2. Fine Milling: Achieving the Perfect Consistency

To create flour suitable for modern baking and cooking, consistent and fine granulation is key. After drying, the cassava pieces are processed through a milling machine. Henan Jinrui's milling equipment is engineered to deliver a uniform and controllable particle size. This precise milling technology is crucial for producing the smooth, lump-free texture that defines high-quality cassava flour.

3. Gentle Drying: Preserving Natural Qualities

The premium cassava flour processing employs a more integrated drying approach to protect the root's intrinsic properties. Drying occurs after grating and dewatering, where controlled temperature management is vital. Henan Jinrui's flash dryer provides a rapid, uniform drying environment. This method efficiently reduces moisture to the optimal level while minimizing heat exposure. The result is flour that retains more of the cassava's natural flavor and nutritional profile.

Transitioning from producing dried cassava chips to manufacturing high-quality cassava starch and flour is essential for improving profitability. This transformation is built upon advanced processing technology. With over a decade of expertise, Henan Jinrui is your partner in this transformation.
