From Fresh Cassava to Cassava Flour: A Complete Dry Process

Turning fresh cassava into highquality flour is a straightforward process when you follow the right steps. The cassava flour dry process is one of the most common and costeffective ways to produce cassava flour, especially for small to mediumscale producers. The cassava flour dry process uses less water, requires lower investment, and delivers a clean, natural product. Henan Jinrui’s complete dry process solution covers six key stages: cleaning, peeling, slicing, drying, milling, and screening.

Washing is the first and essential step in the cassava flour dry process. Its main purpose is to remove dirt, sand, and surface impurities that would otherwise affect product purity and damage downstream equipment. Effective washing reduces microbial contamination and prepares the cassava for the next stages. This process typically uses a dry sieve to remove large debris, followed by a paddle washer that scrubs the roots with water, ensuring thorough cleaning.

Peeling is an indispensable step that significantly improves the color, taste, and safety of cassava flour. The peel contains natural toxins, so removing it enhances product quality and reduces health risks. A sand roller peeling machine is commonly used, achieving a peeling rate of up to 96% while minimizing raw material loss.

Slicing cuts peeled cassava into uniform thin pieces, increasing the surface area for faster moisture evaporation and ensuring even drying. Slice thickness must be controlled properly – too thin may cause over-drying, too thick may prolong drying time. In the dry method cassava flour production line, an adjustable cassava chips machine allows operators to control thickness based on their drying method and final product requirements. Henan Jinrui's cassava slicer can achieve an adjustable cassava chips thickness of 8-30mm to meet different production needs.Built with 304 stainless steel, this slicer offers high efficiency, low maintenance, and consistently uniform chips for optimal drying.

Drying removes moisture from cassava slices to prevent mold and enable milling. Cassava chips can be dried either by sun drying (traditional method) or with a cassava dryer (mechanical drying). In the cassava flour dry process, cassava dryer is often used for large-scale production, ensuring consistent moisture levels and preserving product quality.

Milling is a key stage in the dry method cassava flour production, where mechanical force reduces dried cassava slices into fine powder. The fineness of the flour determines its texture and application. A fine milling machine is commonly used for this step, where screen size can be adjusted to achieve different flour fineness levels, making it suitable for large-scale production due to its simple structure and high efficiency.

Screening is the final quality control step in the dry method cassava flour production, removing coarse particles and impurities to ensure the flour is fine, uniform, and ready for packaging. A sieving machine separates particles by size, and screens with different apertures can be selected for precise control. Modern screening equipment also includes dust removal devices, which help create a cleaner working environment.
